NASA astronauts aboard the International Space Station prepared for a spacewalk scheduled for November 30. Thomas Marshburn and Kayla Barron, whose suits are pictured here in the airlock, will replace a communications antenna on the ISS.
Researchers found Galápagos giant tortoises evolved to quickly kill off cells damaged by stress or aging, which helps explain their extreme longevity. The researchers say treatments mimicking this ability could help fight cancer.
NASA delayed the launch of the James Webb Space Telescope to no earlier than December 22. The telescope will undergo additional testing after an accident NASA described as “a sudden, unplanned release of a clamp band.”
Researchers found organisms that eat monarch butterflies have genetic mutations similar to the ones that let monarchs eat poisonous milkweed. The researchers say it may be the first time the same poison-resistance mutation has been found in multiple steps of the food chain.
NASA found four confirmed and four potential planet-forming disks in the Flame Nebula, 1,400 light years from Earth. They also found radiation from nearby stars is breaking them apart, meaning they may never form planets.
A team of scientists discovered fossilized vertebrae from a two-million-year-old human relative. Combined with previous finds, they form a nearly complete hominid lower back, which suggests Australopithecus sediba was adapted to both walking and climbing.
NASA launched its Double Asteroid Redirection Test mission, which will impact the asteroid Dimorphos in late September or early October 2022. It’s the first mission ever to test the ability to redirect asteroids with spacecraft.
