Alien organisms could hitch a ride on our spacecraft and contaminate Earth, scientists warn | Space

The risk of invading alien organisms is low, but we’re increasing the chances. The growing demand for space exploration is increasing the chances of alien organisms invading Earth and of Earth-based organisms invading other planets, scientists have argued in a new paper. The researchers point to humanity’s record of moving species to new environments on […]

Space Launch Start-Up Just Used A Giant Centrifuge To Fling A Projectile Into The Upper Atmosphere

A U.S. space launch start-up has, for the first time, demonstrated a kinetic-based system that’s intended one day to put small spacecraft into orbit. The SpinLaunch concept, which feels ripped right from the classic age of science fiction, is based around a vacuum-sealed centrifuge that spins an unpowered projectile at several times the speed of […]

Flying Astronauts to Space Is Never Routine – The Atlantic

SpaceX’s first attempt to fly astronauts to space and back was, from start to finish, a success. The launch into orbit—seamless. The spacecraft’s arrival at the International Space Station—smoothly done. On return, the capsule, buffeted by billowy parachutes, coasted through the sky, toward the waters off the coast of Florida—a vision of a new era […]
