 Halfway there! Only 146 million miles to go. Our @NASAPersevere rover is midway through its cruise to Mars. It's set to land in Jezero Crater on Feb. 18, 2021, to study the planet's geology & past climate and search for signs of ancient microbial life: https://t.co/h97c39AKPA https://t.co/bhlUIiWSWR

After capturing more than enough rocks & dust from asteroid Bennu to meet mission requirements, our @OSIRISREx spacecraft is expediting stowing the material in its Sample Return Capsule: https://t.co/qAyvAGBaCl

A team of @NASAGoddard scientists have discovered a rare carbon-based molecule in the thick atmosphere of Titan, Saturn's largest moon. 

This intriguing world is the destination of our forthcoming #Dragonfly mission: https://t.co/KE6p1mQVBn https://t.co/mBR8EgJyeD

LIVE: Our @SOFIATelescope has discovered water on the sunlit side of the Moon — but how much? How could it be used by future #Artemis astronauts? We’re using rovers, spacecraft, telescopes & more in pursuit of answers! Ask our experts anything on @Reddit: https://t.co/REHNvzLgjp https://t.co/ZZWJduCGER

RT @ISS_Research: Over the past 20 years, more than 3,000 experiments have been conducted on the @Space_Station. These studies have led to numerous discoveries and milestones in science and space.
