NASA’s #MissionToPsyche – on its way to explore a rare, metal-rich asteroid – is about to get a speed boost from Mars. 🚀🏁

On May 15, spacecraft will harness the Red Planet’s gravitational pull as a slingshot to increase its speed and adjust its trajectory. 1/2

We’re measuring the height of the ocean from space! 🌎

Data from the upcoming Sentinel-6B satellite will help improve weather forecasts and protect coastal communities. Here are 6 things to know about this new Earth satellite, set to launch Nov. 16: https://t.co/tDe4sazHZE

We have better maps of the Moon’s surface than we do of the bottom of the ocean.

But the SWOT satellite, designed to measure surface water and ocean topography, recently published one of the most detailed maps yet of the seafloor. https://t.co/Tr0YeUCB35

Planning ahead: In addition to its own science goals, @NASAPersevere is helping prepare for future human explorers.

These swatches attached to the rover will help scientists understand how spacesuit materials hold up to the harsh Martian environment. https://t.co/TwmgYVdgGl

During the roughly 24-hour period that Europa Clipper is using Mars' gravity to alter its path, there will be *6* active NASA spacecraft operating on or near the Red Planet – two rovers and four orbiters. https://t.co/I3YFoyKv6o

Thanks to everyone who has reached out to us with concern and support. If you’d like to contribute, this fund will be used by @Caltech & JPL to support our colleagues and their families greatly impacted by the devastating fires. https://t.co/PI0nP0dk8J

“There's still so much that we don’t know, and I actually think that’s kind of cool.”

As @EuropaClipper continues its journey to Jupiter’s icy moon, meet Sarah Elizabeth McCandless, an interplanetary navigator on the team. Hear how her love for exploration has shaped her career.

In case you missed it: Today, NASA's largest planetary spacecraft launched on a 5.5-year, 1.8-billion mile voyage to Jupiter's moon Europa.

Next up... Mars gravity assist in March 2025!

Here are some highlights from today's @EuropaClipper launch 🚀

X marks the spot 🌎

PREFIRE, @NASA's mission to study Earth's poles, has started sending back data!

Expanded vertically, this data from several orbits over Greenland shows how infrared heat emissions vary through the atmosphere: https://t.co/fM4WalN2TB

Was Mars home to microscopic life in the distant past?

An intriguing rock spotted by @NASAPersevere has qualities that fit the definition of a possible indicator of ancient life. But what did we find, and how will we know for sure? https://t.co/vMJScXhqYy

[NASA @NASA]

Our @NASAPersevere Mars rover has found an interesting rock that could be one of the best signs yet that ancient microbial life may have once existed on the Red Planet. However, we'll need to do more research to know for sure: https://t.co/tWpQD6Rcg6

Evidence for two more volcanic eruptions on Venus has been uncovered in @NASA Magellan data by an Italian team of researchers! 🛰️🌋

“The PREFIRE CubeSats may be small, but they’re going to close a big gap in our knowledge about Earth’s energy budget.” -Laurie Leshin, JPL Director

Congrats to @NASA's PREFIRE team on a successful launch! More on the launch and the mission: https://t.co/KV6HrgVOF9

[NASA JPL @NASAJPL]

It's almost launch time for @NASA's PREFIRE mission!

This mission will help us help improve climate predictions by measuring heat in the form of far-infrared radiation emitted from Earth's polar regions. #ReadyAimPREFIRE

Our universe is a wondrous place.

Take a moment. Pause. Look up. Wonder.

Happy #NationalSpaceDay ✨

Flight 72. That’s the final flight for our Ingenuity #MarsHelicopter.

Ingenuity and its team proved that powered, controlled flight on another world was possible. #ThanksIngenuity. You may rest, but your legacy will continue to soar: https://t.co/uEe2ZAw2ML

The sols won’t be the same without the #MarsHelicopter.

#ThanksIngenuity, for being my partner in exploration from the very beginning. https://t.co/mFAg7Lwxnp

[NASA JPL @NASAJPL]

Good news today: We've reestablished contact with the #MarsHelicopter after instructing @NASAPersevere to perform long-duration listening sessions for Ingenuity’s signal.

The team is reviewing the new data to better understand the unexpected comms dropout during Flight 72.
