On this day in 1964 NASA’s Ranger 7 became the first US spacecraft to capture close-up images of the Moon’s surface. The first image, shown here, was 1,000 times clearer than anything ever previously seen. The spacecraft, launched on July 28, 1964, arrived at the Moon three days later and turned on its cameras 17 minutes…

One Year of Moon
Can’t see the video below? Click here. This awesome animation by the visualization folks at NASA’s Goddard Space Flight Center shows the phases and position of the Moon throughout 2011 – a full year of the Moon compressed into 2.5 minutes! What’s really interesting is how you can see the wobble of the Moon in…
iseefaces…on the Moon!
This mound – with craters positioned facelike on its top, including a central peak crater – is located along the edge of the Moon’s Eddington crater, an ancient lava-filled basin on the central western limb. Imaged by the Lunar Reconnaissance Orbiter in January, this 1.5km-wide mound may be the remnants of a volcano. Or it…
Look Inside a Lunar Crater
The crater shown above is located in the lunar highlands and is filled with and surrounded by boulders of all sizes and shapes. It is approximately 550 meters (1800 feet) wide yet is still considered a small crater, and could have been caused by either a direct impact by a meteorite or by an ejected…
Craters Young and Old
This image from NASA’s Lunar Reconnaissance Orbiter Camera (LROC) shows two similarly-sized craters in the Oceanus Procellarum (“Sea of Storms”) region of the Moon – a large mare on the Earth-facing side, on the northwestern edge. One crater is surrounded and covered by boulders and debris, denoting its young age compared to the smooth,…
A Peak Inside
Here’s a close-up look at the central peak of our moon’s Aitken Crater, part of an image captured by the Lunar Reconnaissance Orbiter on January 11, 2010. Taken at an angle, this view offers a nice sense of relief and perspective on a lunar feature not normally visible in direct-overhead shots. The Lunar Reconnaissance Orbiter has…
Where the Sun Don’t Shine
There are places surprisingly close by that are the coldest known spots in the entire solar system: on our Moon’s south pole lie deep craters that never receive direct sunlight, in fact have never seen the Sun, and within these craters lie pockets of ice that contain the same frozen material they’ve had since forming…
Like a Rolling Stone
A boulder leaves a bounding trail in the lunar dust Here’s a neat image for today: a detail of the central peak of Eratosthenes Crater, taken by the Lunar Reconnaissance Orbiter Camera (LROC), shows a trail a rolling boulder has left in the regolith (the fancy word for Moon dirt.) The boulder, located in the…
Rolling Stones
This closeup of a mapping image from the Lunar Reconnaissance Orbiter shows the rolling, bouncing trails left by lunar boulders as they travelled down the slopes of Tsiolkovskiy Crater’s central peak. These boulders, several meters across, lost their footing in the dusty lunar soil at some point and rolled downhill to where they lay now….
Making a Splash
A recent photo taken by the Lunar Reconnaissance Orbiter Camera (LROC) shows a young impact crater in amazing detail, its half-mile-wide interior littered with fused piles of melted rock and encircled by a spray of dark streamers – the “splash” of melted subsurface material from the impact. Boulders and smaller chunks of rock are scattered…
It’s a Small World
Another wonderful image from the Apollo Image Gallery, this scanned film image shows the ascent stage of the Eagle lander as photographed by Neil Armstrong, with the partially-lit Earth floating in the black lunar sky above. This is how our world looks from 239,000 miles away. Basically it would look 4 times larger than the…
A Leap for Mankind
“That’s one small step for [a] man, one giant leap for mankind.” After speaking these historic words at 10:56 EDT on July 20, 1969, marking the moment that humanity first placed a foot on a world other than its own, Apollo 11 commander Neil Armstrong began his work documenting the lunar surface before him. The…
