So what are we to make of the highly ambitious, private Polaris spaceflight?

A white spacecraft, lightly toasted like a marshmallow and smelling of singed metal, fell out of the night sky early on Sunday morning and splashed down in the Gulf of Mexico not all that far from Key West.

The darkened waters there were carefully chosen from among dozens of potential landing spots near Florida. This is because the wind and seas were predicted to be especially calm and serene as the Crew Dragon spacecraft named Resilience floated down to the sea and bobbed gently, awaiting the arrival of a recovery ship.

Inside waited a crew of fourβ€”Commander Jared Isaacman, a billionaire who funded the mission and had just completed his second private spaceflight; SpaceX engineers Sarah Gillis and Anna Menon, who were the company's first employees to fly into orbit; and Pilot Kidd Poteet.

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.

As always, we welcome reader submissions. If you don't want to miss an issue, please subscribe using the box below (the form will not appear on AMP-enabled versions of the site). 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.

Polaris Dawn astronauts perform historic private spacewalk while wearing SpaceX-made suits

12 September 2024 at 23:11

A crew of four private astronauts made history in the early hours of Thursday when they opened the hatch of their SpaceX Dragon capsule and conducted the first commercial spacewalk.Β  The spacewalk, the riskiest part of the five-day Polaris Dawn mission, kicked off at 6:12 a.m. ET when oxygen started flowing into the astronauts’ spacesuits.
