It cost $196billion over 40 years, ended the lives of 14 astronauts and managed to make less than half the flights promised. We can still save them until the tech advances to then reintroduce these species  in other words, save them for another day, he said. But its failures were also large and tragic. The total price tag for the programme was more than twice the $90billion NASA originally calculated. They go down 80 to 100 meters underground and provide readymade shelter from the surface of the moon, which endures major temperature swings, as well as threats from meteorites and radiation.
We can save them until the tech advances to then introduce their typee.
