He was a NASA scientist for 33 years.
A report issued last month by a United States government auditor said Boeing and SpaceX are unlikely to be able to send astronauts to the ISS next year, resulting in a possible gap in the United States presence on the spacecraft.
Also, the organization will declare the crew tasks for the foremost post-certification operation and crew flight tests for both SpaceX and Boeing, in a press conference to be chaired over by Jim Bridenstine, the NASA Administrator.
"I'm incredibly proud of the progress our team has made, and it has been inspiring to watch them work through challenges quickly, while developing a brand new human-rated spacecraft that Boeing, NASA and the nation can be proud of", Mulholland added.
NASA will announce which astronauts will fly with Boeing and SpaceX at an event Friday at the agency's Johnson Space Center in Houston.
"NASA's Commercial Crew Program will return human spaceflight launches to USA soil, providing safe, reliable and cost-effective access to low-Earth orbit on systems that meet our safety and mission requirements", said the official blog.More news: DJ Khaled: 'Demi Lovato is going to be great'

"After the uncrewed flight tests, both companies will execute a flight test with crew prior to being certified by NASA for crew rotation missions". "We want to do some climate science, but we aren't going to do some of the insane stuff that the previous administration did", he said. The company said it has identified the root cause of that incident and will make both operational and technical changes to ensure the valves close properly in the future. DM-2, Crew Dragon's first manned demonstration flight, is still now scheduled for December 2018, as reported by the Inquisitr.
