The Surface of Mars Might Have Gotten an Acid Bath, Obscuring Evidence of Past Life

People have been speculating about the possibility of life on Mars for centuries. But it’s only since the 1970s and the Viking 1 and 2 missions that we have been able to search for it. After many decades, evidence has mounted that Mars may have once supported life (like the existence of flowing water and organic molecules), but evidence of present-day life has remained elusive.

Unfortunately, according to a recent study by an international team of scientists led by the Spanish Astrobiology Center (CSIC-INTA), it’s possible that the surface of Mars was bathed in acid and alkaline fluids that destroyed all evidence of past life. These findings could have serious implications for upcoming missions to Mars, which includes NASA’s Perseverance and the ESA’s Rosalind Franklin rover.

Curiosity Is Going To Spend Its Summer Driving Around a Dangerous Sandy Region on Mars

Do road trips actually require roads? Not if you’re NASA’s Curiosity rover, who is embarking on an extended 1 mile long road trip this summer up the side of Mount Sharp.

The rover will be moving between two “units” of Gale Crater, where it has been exploring since 2014. It’s wrapping up experiments in the “clay-bearing unit”, which resulted in the highest concentrations of clay found during the mission. It’s now moving to the “sulfate-bearing unit”, which is expected to contain an abundance of sulfates, such as gypsum and Epsom salts.

Curiosity Sees Earth and Venus in the Night Skies on Mars

Mars rover Curiosity covered in dust and a combined image it took of Earth and Venus both in the Martian night sky. — Curiosity, seen here covered in dust, took two separate images that have been combined into one showing Earth and Venus in the night sky of Mars.

Normally the images from NASA’s Curiosity rover, currently sitting near “Bloodstone Hill” on Mars, are of alien vistas and rock outcroppings that conspiracy theorists constantly try to anthropomorphize into UFOs. However, the rover is also excellently positioned to capture a unique perspective of an alien sky. And that is exactly what it did recently when it captured an image of both Venus and Earth in the same Martian night sky. The images were actually taken in two separate frames, though the two planets were visible in the sky at the same time.

Better Tires to Drive on Mars

A future rover on Mars may include shape-shifting capabilities. This innovative tech won’t quite be like the liquid-metal polymorphing robot from “Terminator 2,” but will solve a problem that have plagued previous rovers: wheel wear and tear.

NASA’s Glenn Research Center is now using shape memory alloys (SMA) to build better wheels for driving on Mars.

Wheels and Helicopter Attached to Perseverance Rover

This summer, NASA’s Perseverance rover will launch from Cape Canaveral Air Force Base in Florida. When it arrives on Mars (on February 18th, 2021), it will join the Curiosity rover and a host of other missions that are looking for evidence of past and present life on the Red Planet. At present, engineers at the Kennedy Space Center in Florida are conducting the final assembly of the rover in preparation for launch.

With less than 14 weeks to go before the mission’s launch period opens up, several important development milestones have been completed. This includes integrating the rover’s remaining components, like the rover’s six wheels and the small helicopter drone that will help explore the surface. These elements, and a slew of other final preparations, were integrated with the rover over the past few weeks.

Mars 2020’s New Name is… “Perseverance”

Sojourner, Spirit, Opportunity, Curiosity… For decades, NASA’s robotic rovers have explored the surface of Mars looking for clues about its past and subsequent evolution. With every success and discovery, their names became part of the public discourse, infiltrating our vocabulary the same way iconic figures like Armstrong, Einstein, and Hubble did. But what of the next rover that will be sent to explore Mars this summer?

NASA has serious plans for the Mars 2020 rover, the next installment in the Mars Exploration Program after its sister-rover Curiosity. But before this mission can launch and add its impressive capabilities to the hunt for life on Mars (past and present), it needed a proper name. Thanks to Alexander Mather (a grade 7 student from Burke, Virginia), it now has one. From this day forward, the Mars 2020 rover will be known as the Perseverance rover!

The Curiosity rover on Mars has captured the most detailed panoramic image ever taken of the Red Planet’s surface. The image is made from over 1,000 images, containing 1.8 billion pixels of the Martian landscape, with 2.43 GB of high-resolution planetary goodness.

“This is the first time during the mission we’ve dedicated our operations to a stereo 360-degree panorama,” said Curiosity Project Scientist Ashwin Vasavada.

Mars 2020 Will be The Third Time That NASA Has Tried to Send a Microphone to Mars

This summer, between mid-July and early August, the Mars 2020 rover will launch, reaching Mars by February of 2021. Once it touched down in the Jezero Crater, it will carry on in the footsteps of its predecessor – the Curiosity rover. This will include searching for evidence of Mars’ past habitability and the possible existence of life (past and present), as well as a sample-return mission.

To accomplish these tasks, the Mars 2020 rover will be relying on an advanced suite of instruments. One of these is the SuperCam, which includes a camera, a laser, and spectrometers and is mounted to the rover’s mast (or “head”). Once operational, this instrument will be used to study the chemistry and mineralogy of Martian rocks and (with any luck) find evidence of fossilized microbial life on Mars.

A Glitch Caused Curiosity to Freeze in Place. But It’s Better Now

Article updated at 3:40 pm CST, 1/24/20.

NASA’s Curiosity Mars rover experienced a technical glitch last week, causing it to temporarily lose its sense of direction and freeze in its tracks. But the talented rover repair team back on Earth enabled a fix, and Curiosity is now back in action.

For fans and enthusiasts of space exploration, the name Kevin Gill ought to be a familiar one. As a software engineer at NASA’s Jet Propulsion Laboratory who specializes in data visualization and analysis, he has a long history of bringing space exploration to life through imagery. Among his most recent offerings is a very interesting pic taken by the Curiosity rover early in its mission.
