#10YearsAgo today, the GRAIL mission ended as its twin spacecrafts, Ebb and Flow, deorbited to the lunar surface. The mission created a detailed gravitational map of the Moon, providing insight into its structure and composition.

I just want the Trappist-1 system,
7 planets shining bright,
From TRAPPIST-1b to TRAPPIST-1g,
Each one a cosmic sight.

I don't need any presents,
Just the wonder that you bring,
Your planets orbiting around,
The star that makes them sing.

I just want to explore you,
Discover all your secrets, too,
From rocky worlds to gas giants,
The mysteries you hold true.

Chorus:
All I want for Christmas is you,
Trappist-1, oh how true,
All I want for Christmas is you,
The beauty of your cosmic crew.



This week on #SpaceToGround, we celebrate the 50th anniversary of Apollo 17 as #Artemis I successfully splashes down and @NASA_Astronauts prepare for a spacewalk to install a solar array.

This is so cool. Interesting to learn how this hydrology formed

I have a set of those glasses I got from Xtravision, the Irish equivalent of Blockbuster, in the 90s. I'll have to dig them out to look at this.


50 years ago today, the #Apollo17 crew completed its time at the Moon and performed a Trans-Earth injection (TEI) burn to return home. #Apollo50th

ok it’s a bit higher res than my images. You have a slight advantage though.

Up ahead: “Three Forks.” The spot where I’ll drop a set of samples that the #MarsSampleReturn missions could bring back to Earth for closer study. This first set is full of diverse rocks that could help answer if life ever arose here.

She's beautiful. I wish I could see her with my own eyes one day.

I hate to say it, but it definitely looks like the rover might be flipping us off.


This #HubbleFriday view is pretty *stellar*! ⭐

Our #JunoMission is turning its gaze to Jupiter’s volcanic moon, Io.

Juno is expected to complete nine flybys of the Jovian moon, observing how volcanoes interact with Jupiter's aurorae and magnetosphere. go.nasa.gov/3FVXRR0

Oops! The caption on the link says, "JunoCam took this image of Jupiter’s northernmost cyclone (visible to the right along the bottom edge of image) on Sept. 29, 2022." So this isn't Io.

From the first time we saw a volcano on its horizon to these green swirls, Io is full of surprises!


Spectacular spirals 🌀

Two super-Earth exoplanets orbiting a red dwarf star may be "water worlds." They are 218 light-years away in the constellation Lyra, and are unlike any planet found in our solar system. go.nasa.gov/3FToWEu
#NASAExoplanets


Astronomers have long theorized that water worlds exist and @NASAHubble and Spitzer may have provided the best evidence yet. Kepler-138 d is bigger abound than Earth, but much less dense. Water, lots and lots of water, could explain why.

“Without a doubt the most interesting sample returned from the Moon!”

I double-majored in physics and human rights at the University of Connecticut. I wasn’t interested in pursuing physics after college until I took my first astrophysics class with my first woman physics professor. She inspired me to pursue a career in astrophysics. /jcr

In the exciting days after a GRB, I am triggering telescopes, turning their data into a beautiful image of the explosion, and measuring how bright the explosion was. In a typical day, I study our observations of past GRBs to better understand their causes and how they work. /jcr
#NASAUniverse


I use observations from some of the world’s largest optical telescopes to better understand the universe’s most energetic explosions: gamma-ray bursts (GRBs). We can't predict GRBs, and their optical counterparts can fade in hours, so trying to catch them is quite exciting! /jcr
