The persistent rover explores the launch site for the first Mars launch mission

In addition to collecting the first samples from an ancient river delta on the Red Planet, the robotic rover has been exploring flat areas around the Jezero Crater that could serve as a landing site for the Mars sample return campaign.

This ambitious initiative, a joint project between NASA and the European Space Agency, will rely on multiple missions to bring the samples collected by Perseverance and return them to Earth over the next decade. These samples will be the first Martian samples returned to Earth.

“I am a geologist, meteorologist, photographer, etc. I can now add a ‘location explorer’ to the list. I have been looking for locations where a spacecraft returning from Mars can conduct operations – including the first launch pad on another planet ,” read a tweet from Rover’s Twitter account.

As Perseverance searches the site of an ancient lake that existed billions of years ago, it collects rocks and soil. This material is important because it could contain evidence of past microorganisms that would reveal whether life existed on Mars.

Scientists will have the opportunity to use some of the most advanced tools around the world to study these precious specimens.

The path of innovations

The campaign to return samples from Mars to Earth will begin in mid-2020, when a rocket is launched on a mission to Mars carrying a sample retrieval vehicle and a vehicle.

Once the probe reaches Mars, it will land near the Jezero Crater and launch the rover to retrieve samples from areas hidden by perseverance on Mars.

There is also the possibility that Perseverance itself may keep some samples on board and deliver them to the probe.

However, the fetcher isn’t the only spacecraft making its way onto the probe. It will also deliver the Mars Ascent Rover – the first rocket ever launched from the surface of Mars, with samples safely placed inside.

A separate mission will be launched from Earth in mid-2020, called the Earth Return Orbiter, to rendezvous with the Mars Ascent Rover.

Aboard the Earth Return Orbiter is a capture/containment and return system, which will collect a container of samples from the Mars Ascent Rover while both vehicles are in orbit around Mars.

After that, the Earth’s return probe will return to our world. Once the spacecraft approaches Earth, it will launch an Earth-entry vehicle containing cached samples, and that spacecraft will land on Earth in the early to mid-2030s.

The robotic components of the campaign are Currently being tested At the centers of NASA and the European Space Agency.

Finding Mars Pie

In order to land on and take off from Mars, a typical return mission needs a flat surface with a radius of 200 feet (60 meters) with no sand dunes, angled terrain, or boulders more than 7.5 inches (19 cm) in diameter to disturb the region. The flat, unobstructed terrain also makes it easy for the rover to fetch samples.

The persevering craft made a friend on Mars

“The Perseverance team pulled all the stops for us, because Mars sample return has unique needs when it comes to where we work,” Richard Cook, director of the Mars Sample Return Program at NASA’s Jet Propulsion Laboratory in Pasadena, California, said in a statement. .

“Basically, a boring landing spot is a good thing. The flatter and uninspiring the scenery, the better for us, because while there are plenty of things to do when we arrive to pick up samples, sightseeing isn’t one of them.”

NASA's Perseverance craft used one of its navigation cameras to capture this image of the flat terrain of Jezero Crater.  This is one potential location that NASA might consider for a Mars sample return rover.

The sample return team used the rover’s cameras to survey a flat area they call the “landing bar”. The long, flat area like the runway at an airport, previously seen in images taken by orbiters orbiting the planet. Perseverance is able to capture a better view of the earth.

“We’ve been looking at these sites since before the Perseverance landing, but images from orbit can tell you a lot,” said Al Chin, director of Mars Sample Return Systems and Integration Systems Engineering, in a statement.

“Now we have some close up and personal shots of the landing runway that suggests we were right on the money. The landing runway is likely to be our shortlist of potential landing sites and caches for (Mars sample return).”
