On July 26, 2014, from 10:57 a.m. to 11:42 a.m. EDT, the moon crossed between NASA’s Solar Dynamics Observatory (SDO) and the sun, a phenomenon called a lunar transit. A lunar transit happens approximately twice a year, causing a partial solar eclipse that can only be seen from SDO’s point of view. Images of the eclipse show a crisp lunar horizon, because the moon has no atmosphere that would distort light. This image shows the blended result of two SDO wavelengths - one in 304 wavelength and another in 171 wavelength.Image Credit: NASA/SDO

ICO G1 antenna deployment, April 26th 2008. ICO G1 (now Echostar G1) is a communications satellite dedicated to mobile satellite phone service, and was a rare commercial payload on an Atlas 5 rocket (nearly all Atlas 5s are used for NASA or military spacecraft.)
Ranger VII: Lunar surface impact movie, July 31st 1964. The Ranger VII probe was the first fully successful US moon probe, and the first moon probe of any country to send back close up images of the lunar surface. It was launched July 28th 1964, 50 years ago today.

Curiosity: View across Gale Crater, sol 696 (July 22nd, 2014). The hills in the background are actually the rim of the crater, and the rover’s busy driving across the crater floor toward the mountain at the crater’s center.
