Rocket Report: China leaps into rocket reuse; 19 people are currently in orbit

Welcome to Edition 7.11 of the Rocket Report! Outside of companies owned by American billionaires, the most imminent advancements in reusable rockets are coming from China's quasi-commercial launch industry. This industry is no longer nascent. After initially relying on solid-fueled rocket motors apparently derived from Chinese military missiles, China's privately funded launch firms are testing larger launchers, with varying degrees of success, and now performing hop tests reminiscent of SpaceX's Grasshopper and F9R Dev1 programs more than a decade ago.

Each report will include information on small-, medium-, and heavy-lift rockets as well as a quick look ahead at the next three launches on the calendar.

Landspace hops closer to a reusable rocket. Chinese private space startup Landspace has completed a 10-kilometer (33,000-foot) vertical takeoff and vertical landing test on its Zhuque-3 (ZQ-3) reusable rocket testbed, including a mid-flight engine reignition at near supersonic conditions, Aviation Week & Space Technology reports. The 18.3-meter (60-foot) vehicle took off from the Jiuquan launch base in northwestern China, ascended to 10,002 meters, and then made a vertical descent and achieved an on-target propulsive landing 3.2 kilometers (2 miles) from the launch pad. Notably, the rocket's methane-fueled variable-thrust engine intentionally shutdown in flight, then reignited for descent, as engines would operate on future full-scale booster flybacks. The test booster used grid fins and cold gas thrusters to control itself when its main engine was dormant, according to Landspace.

Faced with a tight deadline, NASA and Blue Origin agree to delay New Glenn debut

NASA and Blue Origin announced Friday that they have agreed to delay the launch of the ESCAPADE mission to Mars until at least the spring of 2025.

The decision to stand down from a launch attempt in mid-October was driven by a deadline to begin loading hypergolic propellant on the two small ESCAPADE (Escape and Plasma Acceleration and Dynamics Explorers) spacecraft. While it is theoretically possible to offload fuel from these vehicles for a future launch attempt, multiple sources told Ars that such an activity would incur significant risk to the spacecraft.

Forced to make a call on whether to fuel, NASA decided not to. Although the two spacecraft were otherwise ready for launch, it was not clear the New Glenn rocket would be similarly ready to go.
