Martian Reminder of a Pioneering Flight.  Names related to the first solo nonstop flight across the Atlantic have been informally assigned to a crater NASA's Opportunity Mars rover is studying.

The science team leading NASA’s long-lived Opportunity rover mission is honoring the pioneering solo nonstop trans-Atlantic flight of aviator Charles Lindbergh by assigning key features of the Mars mountain top crater area the rover is now exploring with names related to the historic flight.

Opportunity is now studying an elongated crater called “Spirit of St. Louis” and an unparalleled rock spire within the crater called “Lindbergh Mound” which are [click to continue…]

A shadowed cliff on comet 67P/C-G imaged by Rosetta in Oct. 2014 (Credits: ESA/Rosetta/NAVCAM – CC BY-SA IGO 3.0)

The latest image to be revealed of comet 67P/Churyumov-Gerasimenko comes from October 27, 2014, before the Philae lander even departed for its surface. Above we get a view of a dramatically-shadowed cliff separating two regions on 67P, the high, smooth plateaus of Babi and the boulder-strewn, slumped valley of Aten. Both are located on the larger lobe of the comet, while parts of the Ma’at region on the smaller “head” lobe can be seen in the distance at upper left. (You can see a regional map of comet 67P here.)

The image scale is about 75 cm (2.4 feet) per pixel and the entire image spans 770 meters across – about half a mile. Based on that, the cliff is easily over 190 meters (630 feet) high!

What Are Extrasolar Planets?

For countless generations, human beings have looked out at the night sky and wondered if they were alone in the universe. With the discovery of other planets in our Solar System, the true extent of the Milky Way galaxy, and other galaxies beyond our own, this question has only deepened and become more profound.

Latest image released by NASA of the spatter of white spots in the 57-mile-wide crater on the dwarf planet Ceres. Scientists with the Dawn mission believe they're highly reflective material, likely ice. Credit: NASA/JPL-Caltech/UCLA/MPS/DLR/IDA

The latest views of Ceres’ enigmatic white spots are sharper and clearer, but it’s obvious that Dawn will have to descend much lower before we’ll see crucial details hidden in this overexposed splatter of white dots. Still, there are hints of interesting things going on here. [click to continue…]

Story updated with further details and photos

SpaceX Dragons seem to be flying nearly everywhere these days, coming and going at a record pace to the delight and relief of NASA, researchers and the space faring crews serving aboard the International Space Station (ISS). As one Dragon returned to Earth from space today, May 21, another Dragon prepares to soar soon to space.

The commercial SpaceX-6 cargo Dragon successfully splashed down in the Pacific Ocean at 12:42 p.m. EDT (1642 GMT) today, Thursday, about 155 miles southwest of Long Beach, California, some five hours after it was released from the grip of the stations robotic arm this morning at 7:04 a.m. EDT by the Expedition 43 crew as [click to continue…]

Moon Myths: Looking at Lunar Tall Tales

Turns out it’s all a big cosmic blame game.

Over the centuries, humans have attempted to link the phases of the Moon—especially the onset of the Full Moon—with terrestrial affairs. Heck, terms such as lunacy have even entered into the common lexicon, citing a supposed connection between insanity brought on by the Moon. And we’ve long heard anecdotal tales from police and late shift delivery room workers, who swear that everything, from crime rates to delivery room admissions increase around a Full Moon.

The X-37B, a reusable Air Force space plane launched today, May 20, from Cape Canaveral, Florida, on its fourth mission steeped in mystery as to its true goals for the U.S . military and was accompanied by ten tiny cubesat experiments for NASA and the NRO, including a solar sailing demonstration test for The Planetary Society.

The military space plan successfully blasted off for low Earth orbit atop a 20 story United Launch Alliance (ULA) Atlas V rocket on the clandestine Air Force Space Command 5 (AFSPC-5) satellite mission for the U.S. Air Force Rapid Capabilities Office at 11:05 a.m. EDT (1505 GMT) today, May 20, from Space Launch Complex-41 on Cape Canaveral Air Force Station, Florida.
