ESA’s ExoMars Prepares To Sample Lower Martian Atmosphere

Posted by in category: space

ExoMars will soon start aerobraking in Mars orbit in a years-long effort to sample Mars super-thin lower atmosphere in the ongoing search for trace gases indicative of life and active geology.

ESA’s ExoMars Trace Gas Orbiter is preparing to aerobrake into parts of the unexplored Martian lower atmosphere in search of methane, water vapor and other possible signatures of life on the Red Planet.

Grail satellite analysis indicates lava tubes on the moon could be up to 1000 to 5000 meters wide which would be ideal sites for massive moon colonies

Posted by in category: space

Slight variations in the moon’s gravitational tug have hinted that kilometers-wide caverns lurk beneath the lunar surface. Like the lava tubes of Hawaii and Iceland, these structures probably formed when underground rivers of molten rock ran dry, leaving behind a cylindrical channel. On Earth, such structures max out at around 30 meters across, but the gravitational data suggest that the moon’s tubes are vastly wider.

Other satellites had found the openings of large lunar lava tubes and caves.

  • The Lunar Reconnaissance Orbiter has now imaged over 200 pits that show the signature of being skylights into subsurface voids or caverns, ranging in diameter from about 16 feet (5 meters) to more than 2,950 feet (900 m), although some of these are likely to be post-flow features rather than volcanic skylights.

NASA’s Curiosity Rover Finds Boron Under Ancient Martian Lakebed

Posted by in category: space

NASA’s Mars Curiosity strikes again with the first ever discovery of boron at Gale Crater. This detection of Boron, a telltale chemical signature of evaporated liquid water, gives new impetus to the idea that Mars once had clement weather and habitable conditions.

AI Will Colonize the Galaxy by the 2050s, According to the “Father of Deep Learning”

Posted by in categories: robotics/AI, space

In Brief

  • Jürgen Schmidhuber asserts that, by 2050, there will be trillions of self-replicating robot factories on the asteroid belt.
  • In a few million years, robots will naturally explore the galaxy out of curiosity, setting their own goals without much human interaction.

John Glenn, first American to orbit the Earth, dies at 95

Posted by in categories: biotech/medical, military, space

John Glenn, who captured the nation’s attention in 1962 as the first American to orbit the Earth during a tense time when the United States sought supremacy over the Soviet Union in the space race, and who rocketed back into space 36 years later, becoming the oldest astronaut in history, died Dec. 8 at a hospital in Columbus, Ohio. Mr. Glenn, who in his post-NASA career served four terms as a U.S. senator from Ohio, was 95.

The death was confirmed by Hank Wilson, communications director at the John Glenn College of Public Affairs at Ohio State University. Mr. Glenn had a stroke after heart-valve replacement surgery in 2014, but the immediate cause was not announced.

Mr. Glenn was one of the seven original astronauts in NASA’s Mercury program, which was a conspicuous symbol of the country’s military and technological might at the height of the Cold War. He was not the first American in space — two of his fellow astronauts preceded him — but his three-orbit circumnavigation of the globe captured the imagination of his countrymen like few events before or since. Mr. Glenn was the last survivor of the Mercury Seven.

Vision of a Asteroid Belt Astronomical Telescope and hypertelescopes

Posted by in categories: physics, space

Physics Today has a speculative article that proposes that laser light be used to shape and polish an asteroid to high optical standards. This could create an Asteroid Belt Astronomical Telescope (ABAT).

The Asteroid Belt Astronomical Telescope (ABAT) focuses light from laser-polished asteroids onto dual imaging arrays above and below the solar system; other intense laser pulses maneuver the arrays to different locations, thus allowing ABAT to point at multiple celestial targets. Asteroid ablation residue corralled into a pair of Devil’s Footprints shields the focal regions from solar illumination. (Courtesy of Laura Kim.)
