Members of NASA’s Artemis program revealed just how challenging space exploration can be in the latest video released by the agency. According to the program’s team members, the risk of death is always present due to the harsh conditions of space.

For years, NASA has been planning for its latest spaceflight program dubbed as Artemis. As noted by the agency, the new program’s goals will be sending human expeditions to the Moon and Mars.

In a new video titled “Space is Hard,” team members of NASA’s Artemis program talked about how unforgiving space and space missions can be.

“It’s going to be hard,” one team member said. “There’s a good chance of death. Going in a little can through deep space, it’s a very harsh environment. We think you can come back, but nothing is certain.”

As noted by NASA, there’s always a high level of risk involved when it comes to carrying out activities in space. Due to its unforgiving conditions, one small mistake or minor issue in space could suddenly lead to a catastrophic failure that can threaten the lives of astronauts.

For the members of the Artemis program, these are the kinds of risks and challenges they will face as they lead NASA in its new exploration projects.

“There are all sorts of challenges we will face on deep space missions,” another team member stated. “Communication delays, radiation protection, isolation of the crew.”

“There’s never going to be zero risk,” veteran astronaut Ricky Arnold added. “When you’re breaking the bonds of gravity that’s just part of the deal.”

In preparation for these challenges, the new video released by NASA also showed the rigorous training and procedures astronauts had to go through in order for them to be mission-ready. Through these, the agency noted that it is confident that its Artemis team members are more than ready and prepared to handle the upcoming Mars and Moon missions.

As noted by NASA, the Artemis program will be kicked off with a new crewed expedition to the Moon sometime in 2024. The success of the mission would eventually lead to the first human spaceflight to Mars.
