I remember watching this CGI anime in space like appleseed style.

It's about astronauts traveling to mars and when they go back to earth terrorists attacked them. The captain of the astronauts was female and the rest of the crew are male, when they are near earth they stayed on this space station where her son is at but he is already older than her because of how long she traveled. Then they only managed to refuel and had to rush to leave again for mars because the terrorist were attacking. I remembered that was the twist because when the old guy said goodbye to the astronauts when they are leaving he said goodbye mom.
