Tardigrades, often called water bears, are near-microscopic creatures that can range from 0.05 mm to 1.2 mm in length. They have eight legs with four to eight claws on each.
They can survive just about anywhere, including outer space, can withstand temperatures down to -200°C and up to 148.9°C, and have survived five mass extinctions over the course of around half a billion years.

Two old spacecraft just avoided catastrophically colliding in orbit
A defunct navigation satellite and an old rocket booster have narrowly avoided a collision. If they had hit each other, it would have created two orbiting clouds of hazardous shrapnel that could threaten other satellites

NASA is rushing to hold onto its first sample of asteroid dust before too much leaks into space: 'Time is of the essence'
NASA's Osiris-Rex spacecraft briefly landed on an asteroid called Bennu on Tuesday to collect samples of its rock. But now a valve on the probe's sample-collecting arm won't close, and the bits of asteroid it grabbed are floating away. The team is frantically…

Here's What It Actually Means if a COVID-19 Vaccine Passes Phase 3 Clinical Trials
There are currently at least six COVID-19 vaccines in phase 3 clinical trials – the final phase of testing. These trials all aim to compare the safety and effectiveness of the vaccines versus a placebo.
NASA will announce an exciting new discovery about the Moon from the Stratospheric Observatory for Infrared Astronomy (SOFIA) today at 16:00 UTC / 12:00 ET
This new discovery contributes to NASA’s efforts to learn about the Moon in support of deep space exploration.
As the world’s largest airborne observatory, SOFIA is a modified 747 that flies high in the atmosphere to provide its nearly 9-foot telescope with a clear view of the universe and objects in our solar system. Flying above 99% of the atmosphere’s obscuring water vapor, SOFIA observes in infrared wavelengths and can detect phenomena impossible to see with visible light.
