NASA’s plans to bring astronauts Sunita Williams and Butch Wilmore back to Earth are getting closer. This progress follows the successful completion of a crucial test for Boeing’s Starliner spacecraft. The test, known as the docked hot fire, evaluated the spacecraft’s Reaction Control System (RCS) thrusters and its helium system.

In a press release, Starliner announced that this test was performed for the second time and provided key data for planning the spacecraft’s return. This week, Starliner will conduct two undock-to-landing simulation tests to further prepare for the astronauts’ return.
“A Flight Test Readiness Review is tentatively planned for late next week, and the data gathered today will be reviewed and included in return flight rationale. While a landing date has not yet been set, opportunities are available throughout August,” Boeing Starliner updated on the mission (via Mint).
Chloe Mehring, the flight director for Starliner, praised the collaboration between the Starliner and International Space Station (ISS) teams. “The integrated teams between Starliner and ISS worked extremely well together this week to finalise and safely execute the docked hot-fire sequence.”
During the test, astronauts Williams and Wilmore provided real-time feedback from the Starliner Calypso spacecraft. They are expected to participate in the upcoming undock-to-landing simulations.
Meanwhile, NASA faces challenges with increased traffic at the ISS due to delays and technical issues with SpaceX and Boeing. The agency is also managing an emergency situation involving astronaut sheltering due to debris and propulsion problems.
