Mars Will NOT Be As Big As The Moon In The Night Sky

No, no, no…a thousand times NO: Mars will not become a “second Moon” in the sky on August 27. It won’t this year, it didn’t last year, and it didn’t in the past dozen years since this silly yet strangely perennial cyber-legend (yes I just used the prefix “cyber”) first started circulating on teh interwebz. I don’t know…

This is Our Best Photo of Neil Armstrong on the Moon

Everyone knows that Apollo 11 commander Neil A. Armstrong was the first human to set foot on the Moon (and if you didn’t know, that occurred on July 20, 1969 – yes, it really happened). It was a momentous, history-making event that many (like myself) consider one of the most impressive achievements of humankind. But oddly…

Pluto’s Ice Mountains Revealed in Stunning Detail

At 3 p.m. EDT today, July 15 2015, from the Johns Hopkins University’s Applied Physics Laboratory in Laurel, Maryland, the New Horizons team revealed to the world the first high-resolution image acquired of the surface of Pluto. This was obtained during the historic July 14 flyby with New Horizons’ “Ralph” camera, and it’s our very first close-up view of…

Here’s Our Best and Last Look at Pluto’s Moon-facing Side

Three days before New Horizons’ closest pass by Pluto and we already have the first final image of the mission: this is the last “best” view we will have of Pluto’s Charon-facing side, as the spacecraft will be acquiring its most detailed images of the planet’s opposite side on July 14. Pluto and its largest…

Infographic: Why Would We Mine the Moon?

Our Moon is more than just some pretty decoration for the night sky and a place to plant a few flags – it’s also a potential source of valuable raw materials that could someday be used for energy and engineering both on Earth and in space. If you saw the movie Moon (and if you haven’t…

Curiosity Gazes on Mars’ Moon Phobos

Do you love to look up at the Moon? Well so does NASA’s Curiosity rover! Feel free to correct me if I’m wrong (I have not confirmed this) but this appears to be an image of Phobos, the larger of Mars’ two small moons, imaged by Curiosity’s Mastcam on mission Sol 1002 (June 1, 2015)….

Cassini To Make Its Last Pass Of Hyperion

This coming Sunday, May 31, the Cassini spacecraft will perform its last close pass of Hyperion, Saturn’s curiously spongelike moon. At approximately 9:36 a.m. EDT (13:36 UTC) it will zip past Hyperion at a distance of about 21,000 miles (34,000 km) – which may sound like a lot but but it’s even closer (by 17,500 miles/28,160 km) than it was when the image…

This Was Rosetta’s View of Earth and the Moon in March 2005

ESA’s comet-chasing Rosetta mission is best known today for its two historic firsts of entering orbit around a comet and sending a lander onto the surface of said comet, in May and November of 2014 respectively. But Rosetta didn’t just go directly from its March 2, 2004 launch to comet 67P; it had to perform…

A Northern View of Saturn’s Stained Moon Iapetus

Here’s a raw image of Saturn’s moon Iapetus, looking down on its northern hemisphere from Cassini on March 31, 2015. The moon’s signature two-toned coloration is evident as its bright icy surface is partially coated by dark material, thought to have been ejected from distant neighbor Phoebe. Iapetus is 914 miles (1,471 km) in diameter, or…

Cassini Captures Narrow-Angle, Wide-Spectrum Views of Rhea

After spending a couple of years in an orbit riding high over the northern pole of Saturn Cassini has swung back down alongside the planet’s ringplane, in perfect alignment to once again capture views of the icy moons that reside there. The image above is a composite made from several narrow-angle camera images acquired by Cassini on…
