Many consider the various rovers we’ve sent to Mars as the next best thing to sending a geologist to the Red Planet. Spirit, Opportunity and Curiosity have carried all the necessary equipment similar to what human geologists use on Earth, and are able to navigate the terrain, “see” the landscape with the various cameras, pick up rock and dust samples with scoops, and then analyze them with various onboard tools and equipment.
In addition to all those things, the new Mars 2020 Perseverance rover will add a “sense of hearing” to its robotic toolkit. The rover includes a pair of microphones to let us hear – for the first time – what Mars really sounds like.

Today is a milestone in NASA’s Perseverance mission to Mars. At 1:40 pm Pacific time today, the rover will have traveled 235.4 million km (146.3 million miles). That means the spacecraft is halfway to Mars and its rendezvous with Jezero Crater. The spacecraft isn’t traveling in a straight line, and the planets are moving, so it’s not equidistant to both planets.
“Although we’re halfway into the distance we need to travel to Mars, the rover is not halfway between the two worlds,” Kangas explained. “In straight-line distance, Earth is 26.6 million miles [42.7 million kilometers] behind Perseverance and Mars is 17.9 million miles [28.8 million kilometers] in front.”
But today’s still a good time to take another look at Jezero Crater, and why NASA chose it as the mission’s target.

When NASA’s new Perseverance Martian rover launches in a little over a month it will have a small robotic stow-away on board. Ingenuity is a small helicopter, with a fuselage about the size of a softball and two extending rotors that measure about 4 feet across. It was attached to the bottom of the rover’s chassis in April, and NASA recently released details about it’s technically challenging release process.
Before the team of NASA and Lockheed Martin engineers started designing the release mechanism though, they had to decide what Ingenuity’s mission would actually be. Ultimately, the helicopter will serve as the first powered experimental test flight on any extraterrestrial body. NASA is hoping it will be the first of many, leading to future helicopters on Mars that could allow mission scientists to peer into previously inaccessible places, such as craters and cliffs, from the air. If Ingenuity is successful, it could pave the way to many future air based scientific and scouting missions.

In 2018, NASA decided that the landing site for its Mars 2020 Perseverance rover would be the Jezero Crater. At the time, NASA said the Jezero Crater was one of the “oldest and most scientifically interesting landscapes Mars has to offer.” That assessment hasn’t changed; in fact it’s gotten stronger.
A new research paper says that the Jezero Crater was formed over time periods long enough to promote both habitability, and the preservation of evidence.

Flying low over the surface of Mars. Don’t tell me you haven’t dreamed about it, especially with some of the ‘Mars flyover’ videos that have been produced over the years using data from the orbital missions. And if all goes well – global pandemic not withstanding — a helicopter will be on its way to the Red Planet in just a few months.

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!

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.

NASA’s Mars 2020 Rover is heading to Mars soon to look for fossils. The ESA/Roscosmos ExoMars rover is heading to Mars in the same time-frame to carry out its own investigations into Martian habitability. To meet their mission objectives, the scientists working the missions will need to look at a lot of rocks and uncover and understand the clues those rocks hold.
To help those scientists prepare for the daunting task of analyzing and understanding Martian rocks from 160 million km (100 million miles) away, they’ve gone on a field trip to Australia to study stromatolites.

Back in November 2018, NASA announced that the Mars 2020 rover would land in the Jezero Crater. Jezero Crater is a geologically diverse area, with an alluvial fan of sediment deposited by an incoming river. That sediment may contain preserved ancient organic molecules, and the deposit is clearly visible in satellite images of the Crater.
But the crater holds something else that has scientists intrigued, something that doesn’t show up so clearly in visible light images: a “bathtub ring” of carbonates, which scientists think could hold fossils.

Work on the Mars 2020 Rover is heating up as the July/August 2020 launch date approaches. Mission engineers just attached the Mars Helicopter to the belly of the rover, where it will make the journey to Mars. Both the solar-powered helicopter and the Mars Helicopter Delivery System are now attached to the rover.
NASA’s Mars Helicopter will be the first aircraft to fly on another planet. The small rotor-craft only weighs 1.8 kg (4 lbs.) and is made of lightweight materials like carbon fiber and aluminum. It’s largely a technology demonstration mission, and is important to NASA. The overall mission for the Mars 2020 rover won’t depend on the helicopter, but NASA hopes to learn a lot about how to proceed with aircraft on future missions by putting the Mars helicopter through its paces on Mars.
