Teams completed ground hot fire testing at White Sands and are working to evaluate the test data and inspect the test engine. The ongoing ground analysis is expected to continue throughout the week. Working with a reaction control system thruster built for a future Starliner spacecraft, ground teams fired the engine through similar inflight conditions the spacecraft experienced on the way to the space station. The ground tests also included stress-case firings, and replicated conditions Starliner’s thrusters will experience from undocking to deorbit burn, where the thrusters will fire to slow Starliner’s speed to bring it out of orbit for landing in the southwestern United States.

Integrated ground teams also are preparing for an in-depth Agency Flight Test Readiness Review, which will evaluate data related to the spacecraft’s propulsion system performance before its return to Earth. The date of the agency review has not yet been solidified.

The delayed spacewalk is only the latest in a string of setbacks around operations on the International Space Station in recent weeks.

This marks the second spacewalk in recent days that has been abruptly called off due to spacesuit issues.

In addition to the aborted Monday spacewalk, the federal agency has been aiming to carry out another on July 2 — before giving Boeing’s Starliner capsule the green light to undock from the orbiting laboratory and make its return home.

The Starliner spacecraft has been on its first crewed test flight to the space station. But the vehicle encountered several key issues during the first leg of its trip, including springing helium leaks and experiencing thruster outages, that have delayed its return.

NASA announced Friday that it will award contracts to seven companies, including SpaceX and Blue Origin, to study how to transport rock samples from Mars more cheaply back to Earth.

The space agency put out a call to industry in April to propose ideas on how to return the Mars rocks to Earth for less than $11 billion and before 2040, the cost and schedule for NASA's existing plan for Mars Sample Return (MSR). A NASA spokesperson told Ars the agency received 48 responses to the solicitation and selected seven companies to conduct more detailed studies.

Each company will receive up to $1.5 million for their 90-day studies. Five of the companies chosen by NASA are among the agency's roster of large contractors, and their inclusion in the study contracts is no surprise. Two other winners are smaller businesses.

T-7 hours until the first crewed launch of Starliner!

Launch thread with additional info has been posted over on [email protected]:

Starliner CFT Launch Thread! (First crewed flight of Boeing Starliner capsule)

I will be posting updates there. Come join us in that thread!

After concurring with each of the six recommendations in the inspector general's report, Koerner made the following comment:

"NASA is dedicated to continuous enhancement of our processes and procedures to ensure safety and address potential risks and deficiencies," she wrote. "However, the redundancy in the above recommendations does not help to ensure whether NASA’s programs are organized, managed, and implemented economically, effectively, and efficiently."

A careful reading of the second sentence reveals that Koerner feels that the inspector general's efforts are both redundant and unhelpful. This is not accidental language. Koerner's response was certainly reviewed by NASA's senior managers, who could have flagged and removed the text. And yet they went through with it.
