Spacesuits of the Future Will Be as Flexible as Spidermans
Apart from the flexibility factor, the BioSuit is also safe compared to a traditional spacesuit.
If a tiny meteorite
or other object were to accidentally puncture a traditional spacesuit, the astronaut must return to the space station or home base immediately, before...
Princeton geoscientist offers new evidence that meteorite did not wipe out dinosaurs
A Princeton University geoscientist who has stirred controversy with her studies challenging a popular theory that an asteroid wiped out the dinosaurs has compiled powerful new evidence asserting her position.
