Nasa has unveiled its new class of astronaut candidates, who could fly to the space station and on future missions to the Moon.

They have gone through an interview process with several rounds, team exercises, a thorough medical check and aptitude tests.

The six men and four women were selected from a pool of about 12,000 applicants.

The candidates will now undergo two years of training before graduating.

"We've always had a frontier to expand and the frontier now is upwards, out into the cosmos," said Nasa's administrator Bill Nelson.

The group will participate in what's known as the basic Astronaut Candidate training programme, which is designed to develop the knowledge and skills they will require once they are selected for a flight.

The candidates are required to complete military water survival exercises, fly Nasa's T-38 training jets, and become scuba-qualified to prepare them for the spacewalk training - which takes place in a huge pool at Johnson Space Center in Houston.

Final selection as an astronaut is not guaranteed: they are required to complete the training to a satisfactory level.

Those who do graduate become eligible for flights to the space station and to the Moon - providing Nasa's Artemis programme is not delayed. They are unlikely to be assigned to missions straight away, however; they continue to hone their skills after becoming fully-fledged astronauts.

The new astronaut candidates are:

"Each of you has amazing backgrounds," Pam Melroy, a former Nasa astronaut and the agency'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."

Former US track cyclist Christina Birch offered advice for other budding astronauts. "If you do the little things well, they add up to something big," she explained - perhaps including being able to go into space.

The first astronauts belonging to Nasa's previous class - Kayla Barron and Raja Chari, who graduated in January 2020 - made their first flights into orbit last month. But for other successful candidates, the path to a flight assignment can take several years longer.

Some of the candidates will almost certainly be assigned to lunar missions under Nasa's Artemis programme

Back in the 1990s and 2000s, Nasa had only one way of getting into space - the shuttle. These candidates join the agency at a challenging and complex time, but also an exciting one.

Nasa astronaut Reid Wiseman said: "We are in the golden age of human spaceflight."

America remains a partner in the International Space Station (ISS), so candidates need to understand the systems aboard the orbiting outpost and demonstrate a working knowledge of Russian to communicate with cosmonauts.

Some could be assigned to fly on either of the two spacecraft Nasa has developed to fly to the ISS - SpaceX's Crew Dragon and Boeing's Starliner, once technical issues have been fixed on the latter. Other candidates will be selected for missions to the Moon under Nasa's Artemis programme.

These astronauts will need a deep understanding of Nasa's Orion spacecraft and any landers the agency plans to use to get to the lunar surface. The vehicle to be used for the first lunar landing since 1972 is likely to be based on Elon Musk's Starship craft, currently under development at a SpaceX facility in southern Texas.
