Three NASA Astronaut Candidates Have Maryland Ties
Of 10 people selected to train as NASA astronauts, one is from Potomac, one went to Johns Hopkins, and another went to the Naval Academy.

MARYLAND — Out of more than 12,000 applicants, NASA has chosen 10 astronaut candidates — and three of them have ties to Maryland.
Christopher Williams, a Potomac native; Andre Douglas, a Johns Hopkins graduate; and Jack Hathaway, a U.S. Naval Academy graduate, will complete two years of training before potentially having opportunity to go on space missions.
“Today we welcome 10 new explorers, 10 members of the Artemis generation, NASA’s 2021 astronaut candidate class,” said NASA Administrator Bill Nelson in a news release. “Alone, each candidate has ‘the right stuff,’ but together they represent the creed of our country: E pluribus unum – out of many, one.”

Some of the space missions after finishing training could include:
- research aboard the space station
- launching from American soil on spacecraft built by commercial companies
- deep space missions to destinations including the Moon on NASA’s Orion spacecraft and Space Launch System rocket
“Each of you has amazing backgrounds,” Pam Melroy, former NASA astronaut and NASA’s deputy administrator, told the candidates. “You bring diversity in so many forms to our astronaut corps and you stepped up to one of the highest and most exciting forms of public service.”
