NASA’s Perseverance Mars rover is collecting samples that will be brought back to Earth
and studied for signs of past life. The current plan is for
Perseverance to deliver samples directly to a future lander and ascent
vehicle. But in case that can’t happen, the rover dropped 10 backup
samples in a location within Jezero Crater known as Three Forks. Small
helicopters similar to Ingenuity, which completed its 40th flight this month, could carry the samples back to the lander.
Closer to home, a comet has graced Earth’s skies. Comet 2022 E3 (ZTF)
will make its closest approach to Earth on February 1, and is currently
visible through binoculars or a telescope. Astrophotographers around
the world have captured images of the comet’s stunning green coma.
