Love seeing all my Mars (and Venus) friends at #COSPAR2022 and talking @MAVEN2Mars science. Seriously cannot wait for the next three years of extreme solar and dust conditions at Mars 🚀⚡️🌪 #PI_daily

Today we make a bittersweet goodbye. After years of exploring Mars, transforming our understanding of the Red Planet, @NASA's MAVEN leaves behind a remarkable legacy of discovery. Farewell, MAVEN! Thank you for everything. 🔴🛰️

LIVE: Leaders with NASA's Mars Atmosphere and Volatile Evolution (MAVEN) mission are providing an update on spacecraft operations and discussing the mission's accomplishments. youtu.be/4WALToxcMjo

A new milestone for humankind: The crew of Artemis II are now the farthest any human has ever travelled, reaching a maximum distance of 252,752 miles from Earth. This surpasses the previous record set by Apollo 13 in 1970 by about 4,102 miles.

NASA is building SR-1 Freedom, a nuclear electric propulsion spacecraft, launching to Mars in 2028.  We are proud to announce this during the 250th year of the United States, the mission’s name reflects the spirit of American innovation and exploration.  This mission will bring America’s nuclear power capabilities to space and deliver the Skyfall payload of Ingenuity class helicopters to explore the Red Planet.     Nuclear power and propulsion will be the key to undertaking crewed missions to Mars and exploring the outer solar system.     Space Reactor-1 (SR-1) Freedom will make the next giant leap and accomplish a key component of President Trump’s National Space Policy, bringing nuclear to space alongside @Energy.

Mars used to be warm, watery, and blanketed by a thick atmosphere. What happened? 🤔 NASA’s ESCAPADE mission just turned on its science instruments to find out. These twin spacecraft are helping prep for future human missions to the Red Planet. 🔴☀️ More: go.nasa.gov/4s5bKSm

Space is hard, and your mind wanders to of whether something in transit or launch has damaged something in one of the engines. Well yesterday we saw engine working perfectly on the Blue spacecraft 🚀🛰️. Gold follows next Monday.

After a successful launch on @blueorigin’s New Glenn rocket, our ESCAPADE mission has begun its journey - ultimately destined for Mars. The twin spacecraft will orbit the Red Planet, investigating how the solar wind stripped its atmosphere. go.nasa.gov/47PWiSZ

A huge thank you to the @blueorigin team for getting us mated, encapsulated, transported and stacked. Launch tomorrow, let's get these twins on their way to Mars!! @rookisaacman @RocketLab @SecDuffyNASA @ucbssl

This is great for NASA and I would love to see 10 x $100 million missions like this a year...accepting more risk but with the aim of getting to the science faster and at lower cost. Best of luck to the ESCAPADE, Berkley, Rocket Lab and Blue Origin teams.

We're all buttoned up and ready for our voyage. Mars or Bust!!

Go IMAP! Go Carruthers! Go SWFO-L1! All of at the MAVEN PSG are cheering you on at @LASPatCU! @MAVEN2Mars #PI_daily #launch #nasa

Well over $20B in taxpayer, paid for assets being thrown away for a savings that's literally pennies on those dollars. I'm all for shrinking waste and increasing efficiencies in our government, but this is neither. science.org/content/article/…

Where did all the water on Mars go? For the first time, NASA's MAVEN orbiter has directly observed a process called atmospheric sputtering, which could be described as “doing a cannonball in a pool.” MAVEN's lead scientist explains: go.nasa.gov/4mInt7y

We are no longer the only MAVEN in space! Asteroid 1997 CO23 = 2003 FX119 has been designated "MAVEN" in recognition for the mission's incredible observations of Siding Spring Comet's close encounter with Mars in 2014. Learn more about the MAVEN asteroid: minorplanetcenter.net/db_sea…

The MAVEN science meetings cover #Mars atmospheric science, space weather, aurora, and everything in between. This team is second to none and we can’t wait for more observations at Mars 🚀 #PI_daily

I am so exceptionally proud of our science, our mission and our team. Happy happy birthday MAVEN- it has been such an honor to lead. Here’s to many more! #PI_Daily @MAVEN2Mars

NASA's ESCAPADE (Escape and Plasma Acceleration and Dynamics Explorers) mission is now targeting a launch in 2025. ESCAPADE's two satellites will investigate how solar wind interacts with the magnetic environment of Mars. Learn more: go.nasa.gov/47gFt1j

What happened to Mars' water? 🤔 Learn more about the recent study of water loss at Mars using data from MAVEN and Hubble. ⬇️

In May, the strongest solar activity on Earth in two decades produced aurorae across the UK and other countries. But what does this uptick in solar activity mean for the rest of the solar system? Words by me @BBC_Future bbc.com/future/article/20240…
