mission. The experiment took place on March 27, 2012, producing white clouds to study fast-moving winds high in the thermosphere. The first rocket was launched at 4:58 am EDT, with following launches occurring at 80-second intervals. The star trails result from the extended exposure. [See our full story.]

Here, Meyer (left), also a pilot, and Ed Schneider humorously displayed "cheesehead" hats after showing off one of Dryden's now-retired SR-71 Blackbird aircraft at the Experimental Aircraft Association's convention in Oshkosh, Wisconsin in 1997.

to recent tidal interactions with another galaxy, however no other galaxies exist nearby. Although the galaxy’s spiral structure remains difficult to discern in this image, scientists showed that NGC 4980 has a disc-type bulge, and its rotating spiral structure extends to the center of the galaxy. Image released April 2, 2012.

Stereo Camera (HRSC) on ESA's Mars Express spacecraft provided the basis for the image. If any cave-like structures are associated with the pits, they could have harbored hypothesized microorganisms in the past. Image taken June 22, 2011.

the highest and driest observatory sites in the world. On the left shines the tail of the constellation of Scorpius, the Scorpion. Across the sky stretches the plane of the Milky Way. Elsewhere in this photo, one can see the constellation of Sagittarius, The Archer, looming over APEX’s dish. Also, Messier 7 (AKA Ptolemy’s Cluster), Messier 6 (the Butterfly Cluster), and the Lagoon Nebula all appear here. Image released April 16, 2012.

(from right to left in this image), exposing darker dust underneath the lighter surface material. Now, this follow-up image from February 2012 shows the smaller dark tracks have disappeared, and the larger ones are much less visible. A likely explanation suggests that atmospheric dust falls on the region, again covering the markings.

scientist Robert Manning. Caine rocketed to extraordinary levels of internet stardom when a documentary about his handmade arcade of packing boxes and tape ("Caine’s Arcade") went viral online. Caine's Arcade official Facebook page remarks: "Robert Manning used to make cardboard rockets when he was Caine's age, now he makes real ones." Manning is Flight System Chief Engineer for the NASA's Mars Pathfinder mission. The meeting took place January 23, 2012, before Caine's Arcade became a sensation, as Manning saw a rough cut of the film in November 2011, according to LA Weekly.

ALMA is complete, it will have 54 of the 12-meter-diameter dishes shown. Above the array, the arc of the Milky Way glistens while the moon bathes the scene in an eerie light. ESO Photo Ambassador Stéphane Guisard took the shot, released April 23, 2012. Click the picture to see a larger version of the astounding image.
