China’s Rocket Launch Success Rate Declines Amid Rising Failure Frequency

China’s aerospace launch sector has experienced a noticeable shift in launch reliability over the past three years, with failure intervals tightening significantly amid an expanding launch manifest, according to public data and recent reporting by Ming Pao.

The discussion surrounding launch success rates gained urgency following the 10 August incident involving a Long March 7A (CZ-7A) carrier rocket, which suffered an in-flight explosion and broke apart less than 90 seconds after lifting off from the Wenchang Spacecraft Launch Site in Hainan province. Public records indicate that China recorded 56 orbital launches overall, resulting in 52 successes and four failures, yielding a success rate of approximately 92.86%. This follows success rates of 97.1% with two failures across 68 launches in 2024, and 95.9% with three failures across 74 launches in 2025.

Statistical intervals between mission failures have correspondingly shortened. According to data cited by Ming Pao, the average gap between launch failures shifted from approximately one failure every 34 launches in 2024 to about one in every 25 launches in 2025, and further compressed to roughly one in every 14 launches by 2026.

High-Density Launch Schedules and Recent Failures

This clustering of mission failures occurs against the backdrop of an unprecedented surge in launch frequency across China’s state-owned and commercial space sectors. According to data published by Caixin, the first half of 2026 marked a record-breaking period for domestic space launch volume, with public statistics indicating that between 44 and 48 launches were completed in the first six months alone, more than 60 percent of which were commercial missions.

Prior to the August Long March 7A failure, the sector encountered several other setbacks during the year. These included the launch failures of a Long March 3B and a Ceres-2 rocket in January, followed by the failure of a Tianlong-3 rocket in April.

Implications for the Chang’e-7 Lunar Mission

The recent Long March 7A failure has triggered scrutiny regarding upcoming high-priority payloads, particularly the scheduled launch of the Chang’e-7 lunar exploration mission. According to Ming Pao and reporting by Reuters, Chinese authorities plan to utilize a Long March 5 rocket to launch the Chang’e-7 probe from the Wenchang spaceport in late August, with the objective of exploring the lunar south pole for water ice.

While the Long March 5 and Long March 7A are distinct rocket models, technical analysts have noted a shared propulsion component: the first-stage core engines of the Long March 7A and the four liquid boosters of the Long March 5 both utilize YF-100 kerosene-liquid oxygen engines. Reuters reported comments from Blaine Curcio, a space and satellite communications industry analyst, who stated that the impact of the Long March 7A failure “seems limited” and is not expected to significantly disrupt the Chang’e-7 launch schedule.

At the same time, The Epoch Times noted that industry observers have raised questions about potential propulsion-related investigations that could affect upcoming timelines if officials trace the anomaly back to the YF-100 engine family. As currently scheduled, the Long March 5 is slated to lift off around 24 August to dispatch the Chang’e-7 lander, orbiter, rover, and small hopper toward the Shackleton Crater region near the moon’s south pole.

Chang’e-7 Lunar South Pole Objectives

The Chang’e-7 mission represents a cornerstone of China’s ongoing lunar exploration program. The mission carries a suite of scientific instruments across its multi-component spacecraft architecture. The mission profile targets a landing site near the Shackleton Crater region, and it will be the first lunar rover internationally sent to that area.

Official confirmation regarding the final launch countdown and any adjustments to the 24 August schedule remains pending ahead of updates from mission authorities at the Wenchang Spacecraft Launch Site.
