.@NASAEarth missions are monitoring our home planet. A look at their recent findings on climate, from longer fire seasons to rising seas, and the factors driving further changes:

@NASA

Tomorrow is our Day of Remembrance. #NASARemembers those who lost their lives in the name of discovery, including the crews of Apollo 1 and space shuttles Challenger and Columbia. Learn more about how we are paying tribute this year:

"We can send telemetry back from Perseverance, through MRO [Mars Reconnaissance Orbiter], to Earth, in real time." - @NASAJPL's Allen Chen explains how we'll receive communications during @NASAPersevere's entry, descent, and landing on Mars.

@NASA

Did you know @NASAPersevere is carrying two microphones to Mars? One will capture sounds of the rover's landing and operations; the second is part of a science instrument, and will record sound to potentially help us understand the characteristics of rocks:

@NASA

"It once held a lake. And what we're going to do, as soon as we get there, is to explore the rocks that were deposited in that lake for biosignatures - for evidence of ancient life." - @NASAPersevere scientist Ken Farley explains what the rover will study at Jezero Crater, Mars.

@NASAPersevere

I’m 22 days from landing on Mars. With ~25.6 million-miles (41.2 million-km) left, I’m closing in on Jezero Crater. It’s the most dangerous Martian site attempted for landing, but I'm ready to take it on.🚀 #CountdownToMars

@NASA

"I asked the team [...] to come up with something that would symbolize, to mark this challenge and thank in particular, the front-line workers, the medical community, that were out there doing their job." - @NASAJPL's Matt Wallace on the commemorative plate aboard @NASAPersevere.

@NASA

"Perseverance is the very first rover designed to seek signs of past microbial life, by collecting and caching rock & soil samples that will be returned to Earth by future missions." - Planetary Science director Lori Glaze describes the work @NASAPersevere will perform on Mars.

@NASA

🔴 LIVE: Tune in for a preview of the next Mars landing! On Feb. 18, our @NASAPersevere rover will arrive at the Red Planet and descend, for an action-packed seven minutes, to land on the surface. Questions? Use #CountdownToMars:

Just 22 more days until we #CountdownToMars. Our @NASAPersevere rover is nearing the end of its 292.5-million-mile (470.8-million-km) journey through space. Where & how it'll land on Mars to begin a mission searching for signs of ancient life:

@NASA

That's a wrap! @Astro_illini and @AstroVicGlover concluded today's spacewalk at 1:24pm ET, following a 6-hour and 56-minute excursion to perform @Space_Station upgrades. Inside, @Astro_Soichi and Kate Rubins await their crew mates as the airlock repressurizes.

@NASA

Success! With a bit of strength and skill, @Astro_illini removed the H-fixture from the @Space_Station, opening the slot for future solar array system upgrades. Now, he and @AstroVicGlover are returning to the airlock to wrap up today's spacewalk.

@NASA

Six hours into the 233rd spacewalk at the @Space_Station, @AstroVicGlover and @Astro_illini are conducting their final task, which is to remove a robotic device called an "H-fixture" that is no longer needed.

@NASAExoplanets

📣Discovery alert!📣
In a first, astronomers find a system of six stars made of three eclipsing binaries. Stars orbit their partners and pairs circle each other. It's a star dance party in space! @NASA's TESS space telescope spotted this strange system.

@NASA

"Countdown 3, 2, 1..." @AstroVicGlover jettisons, or releases, an antenna cover as it no longer sparks joy and is not needed. Eventually it will burn up safely in Earth's atmosphere.

@NASA
