My analysis of the China Aerospace Science and Technology Corporation (CASC) launch manifest for the period of July 1 to August 10, 2026, results in a central prediction of 7.5 successful launches. This forecast is built by combining a bottom-up manifest analysis with a top-down historical rate extrapolation.
The bottom-up analysis identifies a cluster of four specific missions scheduled in the first ten days of July: Long March 4C (July 1), Long March 8A (July 2), Long March 6A (July 4), and the Long March 10B (July 10). Assuming these proceed successfully and CASC publishes the required ‘success’ (成功) announcements, they provide a firm baseline of 4.0. Beyond this initial cluster, the manifest for late July and early August is less publicly detailed but is expected to be filled by CASC’s newly announced ‘high-density’ mode for internet constellation deployments (Qianfan and SatNet LEO). Historical patterns in 2026 show that CASC often reveals specific launch dates only days in advance, and their June 2026 activity—with six announcements in 23 days—suggests a capacity for approximately 10.7 launches over a 41-day window if that peak rate is sustained.
However, several factors weight the forecast toward the lower 7-8 range rather than a pure 10+ extrapolation. First, the maiden flight of the Long March 10B (a critical human lunar program vehicle) carries higher technical and scheduling risk. A delay or anomaly on this flight could lead to a temporary launch stand-down for related vehicle families. Second, the July-August window coincides with the peak typhoon season in China, which historically causes weather-related slips at the Wenchang coastal launch site. Third, the resolution criteria are narrow, requiring the specific characters ‘成功’ to appear in official CASC channels; while this is standard practice, any mission where the announcement is delayed past the August 10 cutoff or fails to use that exact terminology will not count.
I weighted the manifest-driven ‘baseline’ scenario (4 scheduled + 3–4 additional constellation missions) most heavily. I assigned lower weights to a ‘high-density’ scenario where the June cadence continues unabated, and a ‘low-cadence’ scenario where maiden flight technical issues or severe weather cause significant schedule compression. This mixture results in an expected value near 7.5 with a concentration of probability between 6 and 10 launches.
The question asks how many distinct orbital launches will receive an official CASC/SpaceChina success post (with “成功” in the headline or first two paragraphs) between 2026-07-01 00:00:00 UTC and 2026-08-10 23:59:59 UTC. Forecasters agree the right resolution metric is CASC success announcements (not third‑party trackers) and that the best historical anchor is CASC’s own July 1–Aug 10 counts from 2020–2025, which ran 4–7 per year (mean ≈5.7, median ≈5.5). Current evidence — CHXLive/Next Spaceflight listing a dense early‑July cluster (likely Long March 4C on Jul 1, LM‑8 on Jul 2, LM‑6A on Jul 4) plus a riskier LM‑10B demo on Jul 10 and lower‑confidence Jul 17 LM‑7 and Jul 31 Jielong‑3 candidates — nudges forecasts modestly above the lower end but not dramatically above the historical mean. Important uncertainties are schedule slips/failures (especially for the LM‑10B demo), whether CASC will post for non‑Long‑March vehicles like Jielong‑3, and UTC cutoff timing for late announcements. Thus most teams place the mode around six CASC success posts, with most probability mass in roughly 4–8 announcements and smaller tails beyond that range.
Forecast: Probability distribution:
We are forecasting the count of CASC-published qualifying “成功” success announcements (headline or first two paragraphs) for distinct orbital launches, during 2026-07-01 to 2026-08-10 inclusive (41 days). Key signals from the analysts broadly agree:
Main uncertainty drivers that widen tails:
Synthesis: I place the median at ~10–11 launches, with most mass on ~8–14, and a modest open-upper tail for ≥16 outcomes.
A naive/amateur forecast would often (a) extrapolate from a slow early-2026 monthly average without incorporating the June 2026 acceleration, or (b) count only the currently listed public-schedule launches (which are often incomplete for China) and understate the total. My synthesis instead anchors on (1) observed recent cadence (June), (2) annual/base-rate consistency checks, and (3) realistic operational/scheduling uncertainty, while explicitly leaving some probability for both stand-down scenarios and a mid-teens surge. Confidence is moderate: the window is near-term, but launch scheduling volatility and the strict “成功” wording criterion keep meaningful uncertainty.
Forecast rationale (numeric):
— Iteration 1 — Across the forecasts, the reasoning converges on a moderate launch count driven by a mix of known early-July missions and CASC’s normal cadence, with uncertainty mainly coming from schedule slips and launch failures.
The collective reasoning points to a forecast built around known early-July launches plus a few additional missions later in the window, with the final count most likely landing in the high single digits or low double digits, but with a plausible lower outcome if several launches slip or fail.
— Iteration 2 — Across the forecasts, the main expectation is for mid-to-high single-digit successful CASC launch announcements during 1 July to 10 August 2026, with a central estimate around 8–9.
The collective reasoning points to a busy but uncertain launch period: historical cadence and near-term scheduling suggest roughly eight successful CASC announcements, while timing ambiguity and operational delays justify a broad plausible range.
— Iteration 3 — The forecasts converge on a mid-single-digit to low-single-digit-to-high-single-digit expectation, with a central estimate around 5–7 successful CASC launch announcements between 1 July and 10 August 2026.
Overall, the collective view is that CASC is likely to announce about six successful launches, with a plausible range centered roughly around 5 to 7.
Overview Forecasters project the number of successful CASC launches during the July 1 to August 10, 2026, window by weighing an exceptionally dense early-summer manifest against severe seasonal weather and technical risks.
Institutional Targets and a Front-Loaded Manifest Historically, CASC’s launch cadence dips during the summer months. However, the corporation is currently operating under immense pressure to meet an aggressive annual target of exceeding 70 orbital missions. This urgency is exacerbated by a launch backlog created by an early-2026 fleet stand-down following a January anomaly.
Consequently, the early July schedule is unusually front-loaded to support both catch-up operations and urgent mega-constellation deployments (such as Guowang and Qianfan). Key scheduled missions include a Long March 4C from Jiuquan, a Long March 6A from Taiyuan, a Long March 8A from Wenchang, the maiden flight of the Long March 10B, and the Chang’e-7 lunar mission. These are expected to be supplemented by routine unannounced military payloads and commercial sea launches.
Weather Constraints and Technical Risks Despite the high theoretical capacity, significant downward pressures frequently throttle China’s summer launch cadence. The most prominent constraint is seasonal weather. July and August align with the peak of the Pacific typhoon and East Asian monsoon seasons. Operations at the coastal Wenchang spaceport—which hosts several critical launches like the Long March 8A, 10B, and Chang’e-7—are highly susceptible to typhoon-induced scrubs, while the inland Xichang site faces heavy seasonal rains.
Furthermore, the Long March 10B is an experimental debut flight. Maiden launches carry an inherently high risk of technical delays or mid-flight anomalies. Should any mission fail, CASC historically grounds related launch vehicles for multi-week safety investigations, a scenario that would drastically curtail the total launch count for the window.
Announcement Protocols Regarding the specific resolution criteria, forecasters note that CASC strictly adheres to boilerplate public relations protocols. Any payload that successfully achieves orbit is practically guaranteed to be announced with the required “成功” (success) terminology across official state channels within hours of orbital insertion. The only notable administrative risk to the count is if a mission launches late in the evening on August 10, where the mandatory verification period could push the official press release past the strict UTC deadline.

The research compiles known scheduled CASC launches in the July 1–August 10, 2026 window (a July 1 Long March 4C from Jiuquan; a July 10–13 maiden Long March 10B test launch from Wenchang per NOTAMs; and a likely August Chang’e‑7 on Long March 5 from Wenchang) and combines those with historical and 2026-to-date launch rates to produce a quantitative estimate. Using CASC’s 2025 cadence (~73 launches, ≈1 launch every 5 days) and the faster 2026 pace to early June (~35 launches in ~5 months, ≈1 launch every 4.3 days), the researcher converts those base rates to the 41‑day target window to get ~8 launches (2025 cadence) to ~9.5 launches (2026 pace), yielding a central estimate of 8–10 successful CASC launches. The writeup also lists key drivers (mega‑constellation deployments, active Long March variants, multiple launch sites), notes operational risks (technical delays, weather, announcement timing), acknowledges strict resolution criteria that could reduce the count (announcements must be CASC official sources, use the Chinese characters “成功”, and be published within July 1–August 10), reports no relevant prediction‑market outcomes found, and gives a forecast range of a conservative lower bound of 6, a central 8–9, and an upper bound of 11–12 qualifying successful CASC launches.

Based on my research, there are at least 2-3 confirmed CASC launches scheduled during your target window:
July 1, 2026: Long March 4C rocket from Jiuquan Satellite Launch Center [16]
July 10-13, 2026: Long March 10B test launch (maiden flight) from Wenchang Commercial Launch Site - NOTAM notices indicate a launch window between July 10-13, 13:00-17:00 daily [9][37]
August 2026 (highly likely): Chang’e 7 lunar south pole mission on Long March 5 from Wenchang - the spacecraft arrived at the launch site in April 2026, with sources indicating launch “in the second half of 2026,” “no earlier than August,” and “likely in August” [16][39][40][41][42]

Your question has very specific criteria that may reduce the actual count:
These criteria mean that even if 8-10 CASC launches occur, some might not generate qualifying announcements, or announcements might be delayed beyond August 10.
No specific markets found for this exact question. I searched for prediction markets on Polymarket, Metaculus, and other platforms but found no active markets forecasting CASC launches for this specific July-August 2026 timeframe. The prediction market ecosystem is currently focused on other topics (politics, AI, economics) [25][26].
Upside risks (more launches):
Downside risks (fewer launches):
Based on historical base rates and known scheduled missions:
Most likely outcome: 8-10 successful CASC launches with qualifying success announcements between July 1 and August 10, 2026, though the strict announcement criteria may result in slightly fewer qualifying for resolution purposes.
I agree with the critic’s main correction: my initial forecast leaned too mechanically on annualized cadence. CASC’s official 2025 total of 73 launches does imply ~8.2 launches in a 41-day window, but launches are clumpy, and the visible July manifest is concentrated in the first 10 days rather than evenly spread. (english.spacechina.com)
I still think the critic may be slightly too bearish. The resolution wording is probably not a large haircut for normal CASC successes: recent official CASC launch articles put “成功” in the headline/first paragraph, including the Jan. 13, 2026 first CASC space launch. (spacechina.com) Also, the near-term manifest is genuinely strong: public trackers list CASC/Long March launches on July 1, July 2, July 4, and a Long March 10B demo around July 10, with Chang’e-7 shown later in August on at least one tracker. (spacelaunchlive.com)
That said, I am now discounting the Long March 10B more heavily. It is a maiden/demo flight, and current tracking notes that the July 10 assignment to the NOTAM window is uncertain. (spacelaunchnow.me) I now treat it as roughly 0.55–0.65 expected qualifying announcements, not a routine near-certain +1. I am also moving Chang’e-7 mostly into the right tail: official reporting says only “second half of 2026” and that the spacecraft is at Wenchang for pre-launch testing, which is consistent with August but not specifically before the Aug. 10 UTC cutoff. (english.news.cn)
My updated synthesis: 3 routine early-July launches are fairly likely to count; 10B is a discounted contributor; the hidden late-July/early-August manifest probably supplies 3–5 more but with high variance; and Chang’e-7 or extra constellation launches provide upside. Qianfan/SpaceSail deployment pressure remains a real reason not to go too low—recent reporting has the constellation reaching around 200 satellites after June Long March launches—but this may already be partly reflected in the July 2/4 cluster rather than additive to it. (english.songjiang.gov.cn)
So I move down from my original median/mean but not all the way to a clearly sub-8 center. My best distribution is now centered around 7–8, with meaningfully more mass on 5–6 and a still-live high tail around 10–12.

(a) Time left until outcome is known: About 6 weeks. The announcement window closes at 2026-08-10 23:59:59 UTC, with final correction/retraction risk checked by 2026-08-12 03:59 UTC.
(b) Outside view: The best reference class is CASC/Long March/Smart Dragon successful orbital launches with same-day official “成功” announcements. CASC reported 73 launches in 2025—about 8.2 launches per 41 days—while 2026 year-to-date Long March records show roughly 30 Long March successes by June 23, plus Smart Dragon activity, implying about 7–8 CASC launches per 41 days at the current first-half pace. In the analogous July 1–August 10, 2025 window, there were about 6 CASC-family launches: 5 Long March launches plus a Smart Dragon 3 on August 8. (spacedaily.com)
(c) Inside view: The schedule as of June 30 is unusually front-loaded: Next Spaceflight lists CASC launches for July 1 Long March 4C, July 2 Long March 8A, July 4 Long March 6A, July 10 Long March 10B, a NET July Jielong 3, and NET August Chang’e 7 on Long March 5. That pushes above the 2025 same-window count, but some items are uncertain: Long March 10B is a debut/recovery-test mission, the Jielong date is only “NET July,” and Chang’e 7 being before August 10 UTC is far from assured. (nextspaceflight.com)
(d) Outcome if nothing changed: If only the currently visible near-term schedule plus a modest number of short-notice constellation/classified launches occur, I would expect 7–8 launches.
(e) Outcome if the current trend continued: June’s high cadence and the early-July cluster would imply closer to 9–10 launches, especially if Qianfan/Guowang deployments continue at short notice.
(f) Expectations of experts and markets: I found no specific market on this exact count. The broad expert/industry expectation is high Chinese launch tempo in 2026, with roughly 140 total Chinese orbital launches discussed in industry reporting, but that includes private/non-CASC providers and therefore overstates the direct reference class for this question. (marketlaunchintel.com)
(g) Unexpected low scenario: Several of the early-July launches slip; Long March 10B is delayed or fails to meet the “successful orbital launch” criterion; Chang’e 7 slips later in August; and CASC publishes fewer qualifying “成功” announcements than usual.
(h) Unexpected high scenario: All four early-July launches succeed and are announced, the July Jielong 3 flies, Chang’e 7 launches before August 10 UTC, and CASC inserts multiple additional short-notice Qianfan/Guowang or classified missions.
Rationale: I anchor on a base rate of roughly 7–8 CASC successful-launch announcements over 41 days: 2025’s annual CASC pace suggests about 8, while the same 2025 calendar window suggests closer to 6. The inside view moves me upward because there are already four dated CASC launches in the first 10 days of the window, plus likely short-notice constellation activity. I do not move all the way to 9–10 as the median because the schedule after July 10 is sparse and uncertain, Chang’e 7 may well occur after August 10, and debut/reusable-rocket tests have elevated delay/failure risk. My median is therefore 8 launches, with a mean just under 8 and a meaningful upper tail to 10–12 if the constellation cadence remains hot.

CASC’s launch infrastructure and national schedule create a concentrated July–early August window that routinely supports multiple Long March orbital missions.
Capacity constraints, pad allocation, and seasonal weather patterns are slow-moving limits on how many missions can be attempted and announced in short order.
Three calendared Long March attempts in the first four UTC days establish a practical lower bound of qualifying success announcements.
Constellation deployment pressure and a dense June launch tempo make additional short‑notice CASC missions plausible through early August.
The Long March 10B debut and a reported July 17 Wenchang slot are conditional pivots whose go/no‑go decisions materially shift the total.
Short‑notice insertions and coordination with commercial constellation customers can add one or more CASC success posts if manifest pressure accelerates launches.
Resolution sensitivity hinges on CASC’s own publication practices and the explicit use of the characters “成功” in its posts, which can exclude otherwise obvious successes.
Residual uncertainty is dominated by debut vehicle failure or delay risk, pad scheduling conflicts, and the separation of CASC versus non‑CASC operators for official announcements.
Forecast (median): 6.2072 successful CASC “成功” launch announcements from 1 July to 10 August 2026.
I treat this as a count of qualifying CASC success announcements, not merely launches. The good news is that CASC’s official launch-success posts very commonly use the literal characters “成功” in the headline or very early text, which matches the resolution rule closely. Recent examples include the June 23, 2026 Long March 7A post, the June 17, 2026 Long March 12 post, the June 16, 2026 Long March 3B post, and the August 9, 2025 Jielong-3 post. That makes me think the main uncertainty is how many successful CASC launches happen in the window, not whether qualifying wording will appear once they do. (spacechina.com)
For the same July 1-August 10 window, I count 4 qualifying CASC announcements in 2023 (July 9, July 23, July 27, August 3), 4 in 2024 (July 5, July 19, August 1, August 6), and 6 in 2025 (July 3, July 15, July 27, July 30, August 4, August 9). That gives a recent same-window base rate centered around 4-6, with a clear upward trend by 2025. (spacechina.com)
The broader annual backdrop is also rising, though not monotonically explosive: CASC says it completed 48 orbital launches in 2023, 51 in 2024, and 73 in 2025. That matters because the 2025 same-window count of 6 came during a much busier overall year than 2023-2024. (spacechina.com)
For 2026 specifically, CASC’s January 13 success post called that mission the 624th Long March flight, while the June 23 success post called that mission the 653rd. That implies 30 Long March launches from January 13 through June 23 inclusive. If I annualize that crudely, it is roughly a low-60s launch year and about 7.1 launches per 41-day span under a uniform-through-the-year assumption. But the historical July 1-August 10 window has run below the full-year average, so a pure pace extrapolation would likely overshoot. (spacechina.com)
I therefore adjust with two opposing considerations. On the bullish side, CASC’s current infrastructure and processes are clearly being tuned for higher cadence: the June 5, 2026 Long March 8 post says that vehicle has entered a “high-density launch mode”; the June 23, 2026 Long March 7A post says launch-site flow has been cut from 35 days to 19 days; and the June 17, 2026 Long March 12 post describes further optimization of rapid launch operations. These all argue that 2026 should sit above the older 2023-2024 window counts. (spacechina.com)
On the cautious side, publicly visible Chinese schedules are still uncertain. As of late June, an external launch tracker listed CASC missions on July 1 (Long March 4C), July 2 (Long March 8A), July 4 (Long March 6A), and July 10 (Long March 10B demo), plus a Jielong-3 mission NET July and Chang’e 7 NET August; the tracker also explicitly notes uncertainty for some payload identities and says the assignment of the July 10 Long March 10B window is uncertain. So I do not treat those as deterministic counts. (nextspaceflight.com)
My quantitative model combines: (a) six currently visible/probable opportunities with different probabilities of actually occurring, succeeding, and being announced in-window; plus (b) a Poisson remainder for additional launches that are plausible given CASC’s current cadence but not yet clearly dated on public trackers. This produces a mean just under 6.0 and a median of 6. In plain language: 5-7 looks like the heart of the distribution, 8-10 is very live if the early-July cluster mostly holds and another couple of constellation/commercial missions appear, while 0-3 would require multiple visible missions to slip out of the window. That is why my distribution is centered at 6, with meaningful right tail but not a double-digit central forecast. (spacechina.com)
I interpret the question as counting qualifying CASC official success announcements between July 1, 2026 and August 10, 2026, not all Chinese launches. In practice, recent CASC launch news tends to map very cleanly onto the resolution rule: the June 5, June 17, and June 23, 2026 launch articles each use 成功 in the headline and the lead paragraph, which is exactly the kind of post this market resolves on. (spacechina.com)
The broad cadence has been rising. CASC says it completed 51 orbital launches in 2024, consisting of 49 Long March launches and 2 Jielong-3 launches, and then 73 orbital launches in 2025, consisting of 69 Long March launches and 4 Jielong-3 launches. The official Long March launch record already lists launch numbers 624 through 652 from January 13 through June 23, 2026, which is 29 Long March launches by June 23. CASC/CALT launch releases also show three Jielong-3 orbital successes on February 12, March 23, and April 11, 2026, bringing the CASC year-to-date total to 32 by June 23. (m.spacechina.com)
Seasonality matters. Using official records, CASC had about 22 launches by late June 2024 (21 Long March launches through June 29 plus the February 3 Jielong-3 mission) versus 51 for the full year, and about 29 by a comparable point in late June 2025 (28 Long March launches through June 20 plus the January 13 Jielong-3 mission) versus 73 for the full year. That means only roughly 40% to 43% of annual CASC launches were completed by late June in the last two years. If 2026 follows a similar shape, 32 launches by June 23 points to something in the mid-70s to around 80 launches for full-year 2026. A simple uniform-time translation of that annual pace would imply roughly 8 launches in a 41-day window, though real launch calendars are lumpy rather than uniform. This is an inference from the official records rather than an explicit official forecast. (spacechina.com)
The exact seasonal analogs are a little lower than that crude annualized baseline. In the July 1 to August 10 window, official records show 4 CASC launches in 2024 (July 5, July 19, August 1, and August 6) and 6 in 2025 (July 3, July 15, July 27, July 30, August 4, plus a Jielong-3 launch on August 9). So the recent same-window base rate is centered around 5, with 2025 already higher than 2024. (spacechina.com)
What pulls me upward from that 4-to-6 historical window is the currently visible early-July manifest and CASC’s demonstrated ability to sustain tighter turnarounds. Public launch trackers currently show three GO Long March missions on July 1, July 2, and July 4, plus a tentative Long March 10B demo on July 10. Separately, official CASC reporting says the Long March 8 entered high-density launch mode, and the Long March 7A processing flow has been reduced from 35 days to 19 days, both of which support a heavier campaign tempo than older same-window analogs. That makes a very low outcome hard to justify unless there are unusual slips or failures. (spacelaunchlive.com)
The main downward adjustments are schedule uncertainty and demo-flight risk. CALT’s own launch record shows a Long March 3B failure on January 17, 2026 before the family returned to success on June 16, so zero failure risk would be unrealistic. The July 10 Long March 10B demo is especially uncertain: the public schedule history shows repeated slips from April to May to June to late July before moving to July 10, and it is still a first test flight. So I do not want to sit right on the crude 8-launch seasonal baseline. My final view is a central estimate of about 7 launches, with most of the probability mass on 5 through 9, modest probability on 10 to 12, and only a thin tail above that. In the code, I model the window as four publicly listed missions with mission-specific success/slip probabilities, plus an additional-launch component represented by a mixture of Poisson rates to account for late-notice Chinese scheduling and uncertainty about how much of the rest of the window is already effectively booked but not public. (calt.spacechina.com)
I center the forecast at about 7.5 qualifying launches, with 7 and 8 as the most likely single outcomes.
My historical same-window baseline from CASC’s own site is 3 launches in the July 1-August 10 window in 2024 (July 5, July 19, August 6) and 5 launches in the same window in 2025 (July 3, July 15, July 27, July 30, August 4). CASC’s annual total also rose from 48 launches in 2023 to 51 in 2024 and then 73 in 2025, so the trend entering 2026 is clearly upward rather than flat. (spacechina.com)
Current 2026 cadence looks higher again. Official sequence numbers show Long March launch number 624 on January 13, 2026 and number 653 on June 23, 2026. The official CALT launch record snippet also shows a Long March 3B failure on January 17, 2026. From those official counts, I infer 30 Long March launches through June 23, of which 29 were successful; adding CASC-announced Jielong-3 orbital successes on February 12 and April 11 yields about 31 successful CASC orbital launches by June 23. That works out to roughly 31 launches in 162 days, or about 7.85 launches per 41-day window if the pace simply continues. This 31 figure is my inference from official launch numbers and official success/failure posts, not a directly published aggregate. (spacechina.com)
The recent operational tempo also supports a higher 2026 summer number. CASC had two successful Long March launches on March 13, then additional successful Long March launches on March 15, March 26, and March 27. Later, CASC posted successful orbital launches on May 31, June 1, June 5 twice, June 11, June 16, June 17, and June 23. CASC also said on March 11 that the Long March 8 series alone was planned for about 15 launches in 2026, and it has described Long March 8 as already being in high-density launch mode; CASC also said the Long March 7A processing flow had been shortened to 19 days. Taken together, that makes a result above the 2024 and 2025 same-window baselines plausible. (spacechina.com)
For the forward-looking part, external trackers already show CASC missions on July 1 UTC via Long March 4C, July 2 via Long March 8A, July 4 via Long March 6A, and around July 10 via a Long March 10B demo flight. Chang’e 7 is listed only as August 2026, so it is a live possibility but not clearly inside the August 10 cutoff. Because those public trackers show only a handful of near-term Chinese launches while CASC’s own recent cadence has been much denser, I treat the tracker manifest as a lower bound rather than a complete manifest; that lower-bound judgment is my inference. (nextspaceflight.com)
The resolution rule is about announcements, not merely launches, and it specifically requires the literal characters 成功 in the headline or first two paragraphs of an official CASC post. Recent CASC success posts fit that pattern directly, including the June 11 Long March 5 article, the June 17 Long March 12 article, and the February 12 Jielong-3 article, so I apply only a small discount from successful CASC launches to qualifying counted announcements. I also keep a small haircut for failure/correction risk, recognizing the January 17 Long March 3B failure. (spacechina.com)
Putting those pieces together, I land on a mean a bit above 7 and below 8, with most probability mass on 5-10 launches, a smaller but meaningful chance of only 3-4 if multiple missions slip rightward, and a thin upside tail if the visible early-July missions all fly and extra late-July or early-August constellation launches are added. That is why my code uses an overdispersed four-scenario mixture centered near 7.5 rather than a narrower single-rate Poisson. (spacechina.com)
I center this forecast on 7 successful CASC-announced orbital launches, with the coded distribution having a mean of about 7.04 launches. My reasoning starts from CASC’s rising base rate: the group said it carried out 48 space-launch missions in 2023, 50 in 2024, and 73 in 2025, so the current equilibrium is already much higher than a few years ago. CASC’s 2026 work conference also described 2026 as a year with many model tasks and high demands. (spacechina.com)
For current-year pace, the cleanest official signal is the Long March serial count. CASC said the final 2025 Long March launch on December 31, 2025 was the 623rd Long March mission, and the June 23, 2026 Long March 7A launch was the 653rd. That implies 30 Long March launches by June 23, 2026. On top of that, official CASC success posts show three Jielong-3 orbital launches on February 12, March 22, and April 11, so I can identify at least 33 CASC orbital launches from official reporting by June 23. Scaled mechanically to a 41-day window, that is about 7.78 launches. (spacechina.com)
The near-term cadence also looks genuinely fast rather than back-loaded accounting. The official CASC news list shows launch-success posts on June 5 (two separate launches), June 11, June 16, June 17, and June 23. CASC’s own articles say the Long March 8 team executed its June 5 mission only 18 days after the previous one, the Long March 7A launch-site flow has been shortened from 35 days to 19 days, and a June 26 CASC article says the new-generation medium-launch-vehicle lines have entered a second-half sprint phase. That argues against assuming a summer slowdown by default. (m.spacechina.com)
There is also visible launch demand right at the start of the resolution window. External trackers currently list a Long March 4C for July 1 UTC, a Long March 8A for July 2, a Long March 6A for July 4, and a tentative Long March 10B demo flight in July; Rocket Spotter currently shows July 10. I do not take those dates literally, but they matter because they show multiple CASC missions already close to flight. I also discount the absence of public schedule entries later in the window, because a recent Long March 12B mission flew with no advance public warning, so China trackers are clearly incomplete lower bounds rather than full manifests. (nextspaceflight.com)
The main reasons I am not even higher are timing and scope. First, some tracked missions are tentative and could slip out of the July 1-August 10 window; Chang’e 7 is only listed as NET August 2026, and one tracker uses an August 31 placeholder, so I give it only a small chance of counting in this market. Second, the resolution is narrower than “anything CASC mentions”: launches where CASC is only a component supplier are out of scope, and CASC’s own June 18 Lijian-1 article is an example of that kind of edge case because it describes CASC’s role as supplying solid motors rather than being the rocket manufacturer or launch-service prime. Third, the market counts successful official announcements inside the UTC window, so a launch that slips to late August 10 or whose announcement posts after 2026-08-10T23:59:59Z would miss. (nextspaceflight.com)
Balancing those effects, I put the center of mass at 7 launches. In words: 5-9 feels like the core range, 10+ needs the current dense cadence to persist with few slips, and 0-2 would require the public and official signals to be badly misleading. The attached code uses a three-scenario Poisson mixture (slower/expected/faster cadence) with mean about 7.04 to reflect both China’s stronger 2026 launch tempo and the real uncertainty around Chinese short-notice scheduling.
Today is June 30, 2026. I am forecasting qualifying CASC success announcements, not merely launches. In practice, that distinction is usually small, because recent CASC orbital launches have generally received same-day official success writeups on spacechina.com: for example on June 1 (Long March 12B), June 11 (Long March 5), June 16 (Long March 3B), June 17 (Long March 12), and June 23 (Long March 7A). That makes the resolution mostly a question of how many CASC-family orbital launches happen in the window and finish with an official success post using “成功.” (spacechina.com)
For a same-window base rate, I looked at CASC official pages for July 1-August 10 in prior years. I identified 4 qualifying official success posts in 2024 (July 5, July 19, August 1, August 6) and 5 in 2025 (July 3, July 15, July 27, July 30, August 4). That historical anchor argues against an extremely high number unless 2026 really is running on a meaningfully faster cadence than the last two years. (spacechina.com)
There is strong evidence that 2026 is indeed faster. CASC said it completed 50 successful launch tasks in 2024 and then 73 in 2025, a record high. On the Long March side alone, official mission numbering rose from the 624th launch on January 13, 2026 to the 653rd on June 23, 2026, which implies 30 Long March flights in 162 days, or about 7.6 Long March flights per 41-day window if sustained. CALT’s launch record also shows Jielong-3 successes on February 12 and April 11, so all-CASC task pace is a bit above the Long-March-only rate. (spacechina.com)
The near-term manifest also supports a nontrivial count. As of June 30, major launch trackers already list CASC missions on July 1 (Long March 4C), July 2 (Long March 8A), July 4 (Long March 6A), and July 10 (Long March 10B demo), plus Chang’e 7 as NET August 2026. Meanwhile, CASC has been compressing operations: the Long March 7A flow has been reduced from 35 days to 19 days; the Long March 12 team said it shortened launch-cycle work by 4 days; and a new Long March 8 vertical-test position lifts annual test/launch capacity for that family to 30. Those facts support a higher 2026 cadence than the 2024-2025 same-window base rates. (rocketlaunch.org)
Still, I do not want to overreact to the bullish signals. The downside risks are real: Chinese manifests are opaque, CASC sometimes launches on short notice, and some expected flights slip; maiden flights such as Long March 10B are especially delay-prone; and Chang’e 7 being “NET August” does not guarantee it lands before August 10 UTC. I also apply a small haircut for the possibility that a launch occurs but does not resolve as a qualifying CASC success announcement inside the window.
My quantitative compromise is a three-scenario mixture over qualifying-announcement counts: a low-cadence scenario centered at 4.5 (35%), a base scenario centered at 6.3 (45%), and a high-cadence scenario centered at 8.5 (20%). This gives an implied mean a little above 6 and keeps meaningful mass on 5-7 while still allowing 8-10 if the current cadence persists. I keep only small probability on 0-2 because four dated CASC launches are already on the calendar in the first ten days of the window, and only small probability above 10 because the window is only 41 days long. (rocketlaunch.org)
Bottom line: my median forecast is 6, my mean is about 6.1, and I think the most likely outcomes are 5, 6, or 7 qualifying CASC success announcements.
