How Government Geologists Recreated the Moon in Flagstaff, Arizona

From July 1969 to December 1972 the astronauts of NASA’s Apollo missions explored the alien landscape of the lunar surface, flag-planting, kangaroo-hopping, shuffling, digging, and Grand Prix-roving across six sites on the Moon. In order to prepare for their off-world adventures though, they needed extensive practice here on Earth so they would be ready to execute the…

Watch Incredible Launch Pad Footage of the Apollo 11 Liftoff

The Saturn V line of heavy launch vehicles used for NASA’s Apollo program were still to this day the most powerful rockets successfully flown, and this video shows an intimate on-pad view of the ignition and liftoff of the Saturn V SA-506 that launched Apollo 11 to the Moon at 13:32 GMT on July 16, 1969….

NASA Releases Thousands of Hours of Apollo 11 Tapes

You’ve undoubtedly heard many times over the historic words uttered by Neil Armstrong when the Apollo 11 LM Eagle touched down in the Sea of Tranquility on July 20, 1969 and when he stepped off the ladder onto the Moon’s dusty, desolate surface later that same day, but the success of the Apollo 11 mission…

A Naked Titan Revealed by 13 Years of Cassini Data

Saturn’s largest moon Titan boasts the distinction of being the only moon in the solar system to have a thick atmosphere…so thick, in fact, that its surface is perpetually hidden from our view—but not from the view of the Cassini spacecraft’s infrared cameras! Cassini, now over ten months gone after its Sept. 2017 plunge into…

Surprise! Jupiter’s Poles are Literally Encircled by Cyclones

If you think that Saturn’s polar storm systems are amazing then you’re gonna love this: Jupiter has them too, and not just a single central storm over each of its poles either. NASA’s Juno mission has revealed that Jupiter has not only polar vortices but also a ring of enormous cyclones spinning in formation around…

THEMIS Takes Deimos’ Temperature

Can you feel the heat? NASA’s Mars Odyssey can see it! This is an image of Mars’ smaller moon Deimos, captured with Odyssey’s THEMIS (Thermal Emission Imaging System) instrument on Feb. 15, 2018. Part of the 7-mile-wide Moon was in shadow, but the sunlit surface area reached temperatures up to 200 K (that’s still pretty…

After 5,000 Sols We See the Face of Opportunity

It’s finally happened—after over 14 years on Mars (14!!!) NASA’s Opportunity rover has turned its arm-mounted camera around to take a look at itself, giving us the very first true “selfie” of the Mars Exploration Rover mission! Hello Opportunity!

This is Earth and the Moon from 40 Million Miles Away

That’s here; that’s home; that’s us—the two bright objects in this picture are Earth and the Moon, imaged by NASA’s OSIRIS-REx spacecraft on January 17, 2018 from a distance of 39.5 million miles (63.5 million km). This is about the distance between Earth and Mars at their closest points to each other (give or take…

It’s Been 32 Years Since We Last Explored Uranus

Voyager 2 may have been the second of NASA’s famous twin exploration spacecraft but it actually launched first, on August 20, 1977. Eight and a half years later it became the first (and, to date, last) spacecraft to visit Uranus, at 31,500 miles across the third largest planet in the Solar System. Voyager 2 made its closest…
