NASA Solar System

Join us as we explore the worlds of our solar system.

[NASA Artemis @NASAArtemis]

Ready for an Artemis update?

Tune in Friday, Oct. 23, at 2 p.m. ET (1800 UTC) to hear our latest progress and accelerated plans for Artemis lunar missions.

Track Psyche's position in real time as it journeys towards its target, which may be a partial core of a planetesimal, a building block of an early planet. https://t.co/H0tHkTPC7m

[NASA Solar System @NASASolarSystem]

Floor it!

NASA’s Psyche spacecraft has fired up its thrusters and is accelerating to the metal-rich asteroid of the same name. Learn more about Psyche’s solar-powered propulsion system, which uses electromagnetic fields to steadily deliver thrust: https://t.co/MifXRy1npL

@ISAS_JAXA_EN GOOD LUCK MMX!

[NASA Moon Base @NASAMoonBase]

The wheels are in motion for Moon Base!

From robotic rovers to lunar terrain vehicles, our latest update highlights progress on the mobility systems that will support early Moon Base development and Artemis exploration.

[NASA Artemis @NASAArtemis]

Two scientists. One unforgettable view of our planet.

What's it like to see the Artemis II Earthrise image through the eyes of a lunar scientist? How about an oceanographer? Jacob Richardson & Ivona Cetinic are here to tell us.

[NASA JPL @NASAJPL]

The Orionid meteor shower, created by tiny pieces of debris from Halley's Comet, peaks on the night of Oct. 21 - 22. Your best chance to see them comes a few hours before dawn, after the bright Moon sets. Find a dark location, give your eyes time to adjust, and look up.

Have a research idea that could advance NASA science? 🔬

NASA plans to release ROSES-27 by January 2027, with over 50 research opportunities spanning astrophysics, Earth science, planetary science, heliophysics, space biology and more.

[NASA Mars @NASAMars]

NASA is also providing MMX with communication and navigation support via NASA's Deep Space Network. The station in Madrid is receiving information from the spacecraft right now! https://t.co/JQ4AmP6uIx

[NASA Solar System @NASASolarSystem]

NASA has been studying Phobos and Deimos at Mars for decades.

See what we've discovered so far, and learn about the many mysteries that remain: https://t.co/dztPvFg3Pj

[NASA Mars @NASAMars]

Go MMX! 🚀

Ready for today's launch of @JAXA_En's mission to the moons of Mars? Liftoff is slated for 3:41 p.m. EDT.

[NASA Solar System @NASASolarSystem]

Explore Phobos and Deimos yourself with our real-time solar system simulator based on real NASA data: https://t.co/Axe3h4xogt

[NASA Solar System @NASASolarSystem]

@Z_is_key @NASAJPL Not in this case, but possibly in future updates.

[NASA Mars @NASAMars]

The MMX spacecraft carries two pieces of NASA hardware: The MEGANE instrument will be key to revealing the origin of Mars’s moons by measuring their elemental composition.

The P-Sampler demonstration will advance capabilities for surface material acquisition in low gravity. ½

Day meets night at the lunar terminator. 🌗

The @NASAArtemis II crew highlighted this shadowy frontier during their close encounter in April. Now it’s your turn to explore! No spaceship needed.

[NASA Space Alerts @NASASpaceAlerts]

It’s #SunDay! Here’s your space weather report for Oct. 9-15:
•3 M-class flares
•0 C-class flares
•19 coronal mass ejections
•1 geomagnetic storm

This video from NASA’s Solar Dynamics Observatory shows the week’s activity. After the Oct. 10 geomagnetic storm, which led to aurora sightings across northern Europe, Canada, and the northeastern United States, it was a relatively calm week on the Sun.

The Moon makes a special guest appearance in this week’s video beginning at about 0:36. Note the sharp outline of the Moon’s edge. That’s because the Moon has almost no atmosphere to scatter sunlight.

At about 2:30, we also see a calibration maneuver, which the spacecraft performs periodically to account for changes in its instruments’ optics over time.

[NASA Mars @NASAMars]

We've studied the moons of Mars from Earth, from orbit, and even in the sky as seen from the surface. (This view comes from the Curiosity rover.) Now, the @JAXA_en MMX mission will see them up close, and even bring a sample home. NASA will be assisting each step of the way. 1/2

Snapshots of Saturn 🪐

OTD in 1997, NASA’s Cassini spacecraft launched to explore the wonders of Saturn.

For more than a decade, Cassini studied the jewel of our Solar System, including its spectacular rings and icy moons. Take a look at some images captured along the way!

[NASA Solar System @NASASolarSystem]

Checking in with two deep space explorers. 🚀🛰️

Our Psyche mission to a metal-rich asteroid launched 3 years ago today, and tomorrow marks 2 years since Europa Clipper set sail for Jupiter's ocean moon Europa.

(The same rocket side boosters were used for both launches!) 1/3
