NASA Solar System

Calling all early birds! 🐦 If you wake up before the Sun this weekend, you’ll be rewarded with a great view of the Moon, Mars, and Saturn.

A total solar eclipse will sweep over Greenland, Iceland and Spain on Aug. 12, 2026. The path of totality misses the U.S., so we're bringing it to you! NASA is heading into the path to study the Sun, and we'll broadcast it live. More details here: go.nasa.gov/4gg4L6w

New Horizons is healthy and cruising through the distant Kuiper Belt after the longest hibernation period of its mission yet. A recent beacon confirmed the spacecraft is operating normally more than 5.7 billion miles from Earth. 🚀🌌 go.nasa.gov/4eUqakx

The @NASAArtemis II astronauts have their Roman boarding passes, do you?! Just three days left to sign up to have your name sent on the Roman space telescope before it travels a million miles away! go.nasa.gov/RomanNames

NASA's Dragonfly mission has reached a major milestone. ✅ After years of design, fabrication, assembly, and testing, NASA’s Dragonfly is starting to look less like a collection of spacecraft parts and more like the rotorcraft that will fly across the surface of Saturn’s hazy moon Titan. go.nasa.gov/4y4Z8hM

Bring @NASA's largest annual hackathon to your city by becoming a Local Lead! 🚀 ✨ Organize a #SpaceApps Local Event ✨ Lead your community in Earth & space science ✨ Gain experience in event planning & community building Local Lead Forms close on July 28: bit.ly/3QP3MQd

Explore and track the current positions of many known near-Earth asteroids — along with our Psyche, Lucy, and OSIRIS-APEX asteroid missions: eyes.nasa.gov/apps/asteroids/

1,000 days in space! 🌌📷 As of today, our Psyche spacecraft has been traveling for a thousand days. Watch for more views of its recent Mars flyby soon! Next stop: the intriguing, metal-rich asteroid 16 Psyche.

Summer is here! ☀️ Ready to get outside? Build a solar oven, learn about clouds, or make a scale model of our solar system! 🪐 This week's NASA EXPRESS has fun activities to beat boredom & keep your STEM skills sharp! Read: conta.cc/4xYigxU

@haya2e_jaxa Congratulations!

Torifune flyby success!! Thank you for your support. Hayabusa2's journey continues onwards 🛰️

@ESA_Hera Go Hera!

Operating across 140 million km of space from ESOC's Interplanetary Control Room (left), ESA’s Hera mission team has upgraded the software running it - leaving the spacecraft ready to explore the distant Dimorphos and Didymos asteroids this autumn esa.int/Space_Safety/H…

NASA's Dragonfly will explore Titan – a moon with rivers, dunes, and thick atmosphere – unlike anywhere we've ever visited. Join us July 16 at 2pm ET for a behind-the-scenes look at the mission. Bring your questions & set a reminder here: youtube.com/live/nQeXWoPfU…

To explore farther into the universe, we also have to understand our home. 🌎 With more than 20 satellites, NASA tracks Earth’s land, ocean, ice, and atmosphere to help communities thrive. This unique view from space serves all life below. go.nasa.gov/4axfEgp

NASA's CAPSTONE completes its mission testing new technologies around the Moon. From being the first spacecraft to verify a unique lunar orbit for science and exploration missions to serving as a testbed for cutting edge communication and autonomous navigation tools, CAPSTONE advanced @NASA_Technology that will support a sustained human presence on the Moon.

What's Up for July? A predawn meetup between the Moon and planets, a returning comet, dark skies for the Milky Way, and Saturn's unusually thin rings.

Happy 250th, America! 🇺🇸 Red (Mars), white (Moon), and blue (Earth) brought to you by the solar system.

This view of an American flag on metal recovered from the site of the World Trade Center towers after their destruction was taken on Mars on Sept. 11, 2011. The aluminum component bearing the image of the flag served as the cable guard for a tool on the Opportunity rover. 4/6

High-flying flags! 🇺🇸🚀 As we mark America’s 250th, here are some of the banners that NASA spacecraft have carried on their journeys through the Solar System. NASA Mars exploration: Putting the red in "red, white, and blue" since 1976! This view comes from Viking 2. 1/6

The New Horizons spacecraft in November 2005, prior to its launch toward Pluto, the Kuiper Belt, and beyond. 3/6

Voyager 2, seen here before its launch in 1977. Only one American flag has flown farther from Earth than this one - the flag aboard Voyager 1. Both of the twin Voyager spacecraft are now traveling through interstellar space. 2/6
