Elon Musk offered SpaceX’s services to help NASA make its next-generation spacesuits, after a watchdog report on Tuesday said the agency’s current program is behind schedule and will cost more than $1 billion.“SpaceX could do it if need be,” Musk wrote in a tweet.Musk’s company has developed and made flight suits for astronauts who launch into orbit in SpaceX’s Crew Dragon spacecraft. The flight suits are primarily designed to protect the astronauts in case of a fire inside of the spacecraft, or if the cabin depressurizes. Building spacesuits would be a more complex and challenging endeavor, given the need to survive outside of a spacecraft in the harsh environment of space.NASA spokesperson Monica Witt, in a statement to CNBC on Musk’s offer, pointed to the agency’s request last month to companies in the space industry for feedback on “purchasing commercial spacesuits, hardware, and services.”Musk’s proposal came in response to a report by NASA’s inspector general – which is the investigative office which audits the agency for fraud and mismanagement – on the work being done to develop a new line of Extravehicular Mobility Units, which are informally called spacesuits.Astronauts on board the International Space Station use spacesuits “designed 45 years ago for the Space Shuttle” program, the report noted. The IG also highlighted that those spacesuits have been “refurbished and partially redesigned” over the past decades to continue working.The space agency has started three different spacesuit programs since 2007, the inspector general found, and has spent $420.1 million on development since then. Additionally, the report said NASA “plans to invest approximately $625.2 million more” on development, testing and qualification to complete a suit for a demonstration on the ISS and two suits for the crewed mission to the moon – for a total cost of “over $1 billion” through 2025.cnbc.com
