In another SpaceX milestone, billionaire Jared Isaacman and company crew trainer Sarah Gillis took turns floating just outside their Crew Dragon capsule early Thursday in the first privately-financed spacewalk in the history of space exploration.

Polaris Dawn crew gears up for Thursday spacewalk

September 12, 2024 William Harwood

Billionaire Jared Isaacman and SpaceX crew trainer Sarah Gillis prepared to open the forward hatch of their Polaris Dawn spacecraft early Thursday to take turns floating outside in the first non-government spacewalk in the history of space exploration. Depressurizing the spacecraft will begin around 2:23 a.m. EDT (0623 UTC) and a scaffold-like “Skywalker” assembly extending just above the hatch will be used for stability.

Starliner lands safely in New Mexico

Despite NASA’s concerns about earlier thruster problems and multiple helium leaks in the ship’s propulsion pressurization system, the Starliner had no trouble undocking and moving away from the station at 6:04 p.m. EDT and executing a critical 59-second deorbit braking maneuver at 11:17 p.m. to drop out of orbit.

NASA rules out bringing astronauts home on Boeing’s Starliner

After weeks of debate, NASA has ruled out bringing two astronauts back to Earth aboard Boeing’s Starliner capsule because of lingering concerns about multiple helium leaks and degraded thrusters, both critical to a successful re-entry, officials said Saturday.

SpaceX to launch privately-financed international crew of four around Earth’s poles

A blockchain entrepreneur, a cinematographer, a polar adventurer and a robotics researcher plan to fly around Earth’s poles aboard a SpaceX Crew Dragon capsule by end of year, becoming the first humans to observe the ice caps and extreme polar environments from orbit, SpaceX announced Monday.

NASA ‘getting more serious’ about backup plan to bring Starliner astronauts home if needed

August 7, 2024 William Harwood

As NASA debates the safety of Boeing’s Starliner spacecraft in the wake of multiple helium leaks and thruster issues, the agency is “getting more serious” about a backup plan to bring the ship’s two crew members back to Earth aboard a SpaceX Crew Dragon, officials said Wednesday.

Make-or-break tests on tap for Boeing’s Starliner capsule

Critical tests are on tap this weekend to confirm Boeing’s Starliner capsule can safety carry its two-person crew back to Earth despite unexpected helium leaks and degraded maneuvering thrusters, officials said Thursday.

NASA plans for space station’s demise with new SpaceX ‘Deorbit Vehicle’

July 18, 2024 William Harwood

The ISS Deorbit Vehicle, or DV, will be a custom-built, one-of-a-kind spacecraft needed to make sure the space station re-enters the atmosphere at the precise place and in the proper orientation to insure any wreckage that survives the 3,000-degree heat of re-entry will crash harmlessly into the sea.

Starliner crew confident spacecraft will bring them safely home

July 11, 2024 William Harwood

Helium leaks and thruster issues prompted NASA to extend their stay aboard the space station indefinitely — Wednesday marked their 35th day in orbit — while engineers carry out tests and analysis to better understand what caused the problems and to make sure the spacecraft can safely being Wilmore and Williams home.

Starliner landing now on indefinite hold for more tests, but NASA insists crew not ‘stranded’ in space

June 29, 2024 William Harwood

The problem for NASA and Boeing is that the Starliner’s service module, which houses the helium lines, thrusters and other critical systems, is discarded before re-entry and burns up in the atmosphere. Engineers will not be able to study the hardware after the fact and as a result, they want to collect as much data as possible before NASA astronauts Butch Wilmore and Sunita Williams head home.
