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…

Yes, We *Really* Went to the Moon in 1969

The Moon landings weren’t a hoax. Here’s proof.

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…

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…

OSIRIS-REx Sees the Moon Like We Can’t

On September 22 NASA’s OSIRIS-REx spacecraft made a “slingshot” gravity-assist pass by Earth in order to adjust the angle of its flight toward Bennu. Mission scientists took the opportunity to test out the spacecraft’s cameras with planned observations of Earth and the Moon, and I’m happy to report that everything worked out perfectly! Some of…

Our Moon Could Be Conveniently Full of Water

It’s been known for a while (especially since the 2009 LCROSS impact experiment) that there is water on the Moon. But so far the largest volume has been found as ice inside the shadowed walls of craters on the Moon’s south pole, likely originating from ancient comet impacts. Now, using data collected by India’s Chandrayaan-1 lunar…

This Day in Space History: One Small Step

Note: This is an updated article from 2012. “That’s one small step for a man… one giant leap for mankind.” I’m not sure what else need be said about the significance of what happened on this day in 1969 other than it was a shining moment in human history, and will be — should be…

How NASA’s Lunar Orbiter was Struck by a Meteoroid and Survived to Tell the Tale

On October 13, 2014, something rather…striking…happened to one of the cameras aboard NASA’s Lunar Reconnaissance Orbiter (LRO), which has been imaging the Moon from lunar orbit since 2008. The Lunar Reconnaissance Orbiter Camera (LROC), which normally produces beautifully clear images of the lunar surface, produced an image that was wild and jittery. From the sudden…

These Photos Taken from the Moon Show Lots and Lots of Stars

One of the favorite allegations by those who continue to be skeptical of the Apollo moon landings is that there are no stars visible in the photographs taken by the astronauts while they were “supposedly” on the Moon. Now while there’s a rather short but succinct list of why that’s the case (and feel free to review those…

Recent Analysis of Apollo Data Proves the Moon is Hollow

New analysis of data acquired by seismometers placed on the Moon’s surface in the early 1970s and laser measurements taken during recent lunar meteor impact events appears to support an ongoing, if unpopular, hypothesis that our Moon is in fact hollow.
