Hubble Space Telescope Advent Calendar 2008
As we head into the traditional western Holiday Season, I'd like to present this Hubble Space Telescope imagery Advent Calendar. Every day, for the next 25 days, a new photo will be revealed here from the amazing Hubble Space Telescope. As I take this chance to share these images of our amazing Universe with you, I wish for a Happy Holiday to all those who will celebrate, and for Peace on Earth to everyone. - Alan
Earth From Mars
This is the first image ever taken of Earth from the surface of a planet beyond the Moon. It was taken by the Mars Exploration Rover Spirit one hour before sunrise on the 63rd Martian day, or sol, of its mission. (March 8, 2004) The image is a mosaic of images taken by the rover's navigation camera showing a broad view of the sky, and an image taken by the rover's panoramic camera of Earth. The contrast in the panoramic camera image was increased two times to make Earth easier to see.The…
Earth from Mars – Climate Change: Vital Signs of the Planet
This photo from NASA’s Curiosity rover shows the Earth as seen from the surface of Mars, shining brighter than any star in the Martian night sky. Earth is the bright point of light a little left of the image’s center and our moon can be seen just below Earth. Curiosity, which landed on the red planet on August 6, 2013, is the largest and most advanced rover ever sent to Mars. It studies the geology of its surroundings and has found evidence of a past environment well-suited to support…
Europa's Hidden Ice Chemistry
NASA image release October 4, 2010 The icy surface of Europa is shown strewn with cracks, ridges and "chaotic terrain," where the surface has been disrupted and ice blocks have moved around. New laboratory experiments show that water ice and frozen sulfur dioxide react even at the frigid temperatures of Europa. Because the reaction occurs without the aid of radiation, it could take place throughout the moon's thick ice layer—an outcome that would revamp current thinking about the chemistry…
Gemini 9A splashdown, Gene Cernan and Thomas Stafford, June 6, 1966
WIKIPEDIA: Reentry: Gemini 9 splashes down at 9:00 A.M., June 6, 1966. The day of the EVA was also their last in space. On their 45th revolution of the Earth, the crewmen fired the retrofire rockets that slowed them down so that they would reenter. This time the computer worked perfectly, meaning they landed only 700 meters from the planned landing site and were close enough to see the prime recovery ship, USS Wasp. The splashdown happened closer to the recovery ship than any other manned…
NASA Spacecraft Photographs Venus as Seen from Saturn
Venus gleams over Saturn's enormous shoulder in two stunning new photos captured by NASA's Cassini spacecraft, which is orbiting the ringed planet.
Exactly Five Years Ago, the New Horizons Team Discovered 2014 MU69
The New Horizons spacecraft launched on January 19, 2006 – beginning its odyssey to Pluto and the Kuiper Belt. New Horizons now continues on its unparalleled journey of exploration with the close flyby of a Kuiper Belt object called 2014 MU69 – nicknamed Ultima Thule – on January 1, 2019.
