Is There Life on Mars in Subglacial Lakes?

by

Venus may harbour life some 50km above its surface, we learned a couple of weeks ago. Now a new paper, published in Nature Astronomy, reveals that the best place for life on Mars might be more than a kilometre below its surface, where an entire network of subglacial lakes has been discovered. Mars was not always so cold and dry as it is now. There are abundant signs that water flowed across its surface in the distant past, but today you’d struggle to find even any crevices that you could call moist. There is nevertheless plenty of water on Mars … Read more

SPACE: Did Mars Steal Our Second Moon?

An asteroid trailing after Mars could actually be the stolen twin of our moon. The asteroid in question, called (101429) 1998 VF31, is part of a group of trojan asteroids sharing the orbit of Mars. Trojans are celestial bodies that fall into gravitationally balanced regions of space in the vicinity of other planets, located 60 degrees in front of and behind the planet. Most of the trojan asteroids we know about share Jupiter’s orbit, but other planets have them too, including Mars and Earth too. Full Story From Live Science

NASA Heads Back to mars

Mars - NASA

NASA’s newest Mars car will touch down on the Red Planet less than 100 days from now. The life-hunting Mars 2020 Perseverance rover, which launched on July 30, is scheduled to land inside the 28-mile-wide (45 kilometers) Jezero Crater on the afternoon of Feb. 18, 2021 — just 97 days from Friday (Nov. 13). The home stretch will be busy for the car-size robot’s handlers. “While we call the six-and-a-half-month trip from Earth to Mars ‘cruise, I assure you there is not much croquet going on at the lido deck,” mission project manager John McNamee, of NASA’s Jet Propulsion Laboratory … Read more

Musk Declares Mars a “Free Planet”

SpaceX will not recognise international law on Mars, according to the Terms of Service of its Starlink internet project. Elon Musk’s space company will instead reportedly adhere to a set of “self-governing principles” that will be defined at the time of Martian settlement. Musk revealed plans to create a self-sustaining city on Mars last week, though no timeframe is yet to be put in place for its development. Any future colony created by SpaceX would likely use constellations of Starlink satellites orbiting the planet to provide internet connection to people and machines on the surface.

SPACE: “Starman” Just Zipped Past Mars

by
Starman - SpaceX

Starman — the dummy riding a cherry-red Tesla Roadster through space — has made his closest approach ever to Mars. That electric convertible with its mannequin passenger bolted to the top of a Falcon Heavy rocket as a stunt during the SpaceX rocket’s first test launch Feb, 6, 2018. (It’s common for test launches to include heavy payloads, but they’re usually more boring than cherry-red sportscars.) Two years later, the Falcon Heavy upper stage and the vehicle at its tip are making their second trip around the sun. Jonathan McDowell, a Harvard astrophysicist who tracks space objects as a side … Read more

SPACE: SpaceX Could Launch Unmanned Mission to Mars in 2024

by
SpaceX Starship

SpaceX is almost ready to start building a permanent human settlement on Mars with its massive Starship rocket. The private spaceflight company is on track to launch its first uncrewed mission to Mars in as little as four years from now, SpaceX’s founder and CEO Elon Musk said Friday (Oct. 16) at the International Mars Society Convention. “I think we have a fighting chance of making that second Mars transfer window,” Musk said in a discussion with Mars Society founder Robert Zubrin. You can watch a replay of the talk here. That window Musk referred to is a launch opportunity … Read more

SpaceX to Test “Mars Colonizing Spaceship”

SpaceX Mars Spaceship - SpaceX

The next big leap for SpaceX’s Mars-colonizing Starship spacecraft appears to be right around the corner. Two full-size Starship prototypes, known as SN5 and SN6, recently performed 500-foot-high (150 meters) test hops at SpaceX’s South Texas facilities, near the village of Boca Chica. And the next vehicle in line is nearly ready to soar much higher, company founder and CEO Elon Musk said. “SN8 Starship with flaps & nosecone should be done in about a week. Then static fire, checkouts, static fire, fly to 60,000 ft [18,300 m] & back,” Musk said via Twitter on Saturday (Sept. 12). Full Story … Read more

Does Mars Have Hidden Underground Lakes?

by
Mars Lakes - NASA

Remnants of water once found on the surface of Mars may be hidden in a handful of small lakes below the Red Planet’s south pole, and more could exist, according to new research. For decades, researchers have suspected that water lurks below the polar icecaps of Mars, just as it does here on Earth. In 2018, scientists detected evidence for such a reservoir on the Red Planet — signs of a lake about 12 miles (19 kilometers) across and hidden below about a mile (1.5 km) of ice at the south pole of Mars. At the time, the researchers said … Read more

SPACE: An Icebound Mars?

Early Mars may not have been quite the warm, wet paradise scientists have hoped for — not if the valleys scarring its surface work the same way as their counterparts here on Earth do. That’s the conclusion of new research that tried to suss out what the Red Planet really looked like during its first billion years by analyzing more than 10,000 segments of valleys on Mars. In particular, the scientists were inspired by the look of Devon Island in the Canadian Arctic, which is dry and frigid. According to the new analysis, some Martian valleys may have been formed … Read more
