NASA scientists journey to Nevada to check the Perseverance rover’s sensors and navigation know-how in preparation for its 2021 arrival on Mars
- A crew of NASA scientist traveled to Nevada to check the subsequent Mars rover
- As a substitute of bringing the total rover, they introduced simply its sensors and onboard instruments
- One other crew of 150 distant operators practiced issuing instructions and amassing samples to simulate how the actual rover shall be piloted on Mars
NASA scientists gathered in a dried lake mattress in western Nevada to conduct one final spherical of actual world testing earlier than the Perseverance rover departs for Mars this summer time.
As a substitute of transporting the precise rover to Nevada, a bunch of seven NASA scientists stood in for the car-sized car and took instructions from a separate crew of 150 NASA operators working remotely all world wide.
The distant crew entered instructions about the place to ship the simulated rover, and the seven-person crew in Nevada would bodily transfer, together with all of their sensor and assortment units, to the desired location.

A crew of NASA scientists traveled to western Nevada for one final main discipline take a look at of the Perseverance rover’s numerous sensor and assortment tools to permit the crew of distant operators an opportunity to difficulty instructions in a reside setting
The challenge, referred to as Rover Operations Actions for Science Crew Coaching (ROASTT), was designed much less as a take a look at for Perseverance’s techniques than to provide the crew working it an opportunity to see how controlling the rover in a reside scenario may go.
‘It is particularly essential for scientists who’re new to Mars rovers,’ the Jet Propulsion Laboratory’s Raymond Francis mentioned in an interview with the JPL website.
‘It is a crew effort, and everybody has to learn the way their roles match into the entire mission.’
The testing allowed the crew of distant operators to work via sensible issues like debates about the place to pilot the rover primarily based on footage from an onboard digicam, and the way to establish explicit rocks or different environmental particles for assortment given the restricted quantity of storage choices.
The workout routines additionally gave the crew the prospect to check among the rover’s extra technical tools, together with a conveyable X-ray gadget and a radar sensor able to taking readings from beneath the floor of the bottom.
When the Perseverance rover lands on Mars on February 18, 2021, it will likely be managed remotely by a crew of 150 NASA operators, all working remotely from everywhere in the world
Within the testing, the distant operators noticed the panorama and readings from the assorted Perseverance sensors and issued instructions to the crew of seven NASA scientists on the bottom about the place to go subsequent or what samples to select up
Whereas the crew did not carry alongside the total rover, they introduced a lot of its essential instruments, together with a conveyable X-ray sensor and a radar gadget able to taking readings from beneath the floor of the bottom,
‘The subsequent time we do that shall be on Mars,’ JPL’s Ken Williford, one of many mission’s deputy challenge scientists. ‘We have got to get the suitable samples. Let’s carry them again.’
The Perseverance rover is anticipated to launch someday between July 17 and August fifth, arriving at Mars’ Jezero Crater on February 18, 2021.
The mission is a part of NASA’s bigger Artemis program that may hopefully culminate with a human expedition to the purple planet someday within the 2030s.
NASA hopes the samples and analysis carried out by Perseverance will give scientists new perception into whether or not life there actually was microbial life on Mars up to now.
WHAT DO WE KNOW ABOUT NASA’S MARS 2020 ROVER?
Nasa’s Mars 2020 rover will seek for indicators of historic life on Mars in a bid to assist scientists higher perceive how life developed on our personal planet.
The machine will discover an historic river delta throughout the Jezero Crater, which was as soon as crammed with a 1,600-foot (500-meter) deep lake.
It’s believed that the area hosted microbial life some three.5 to three.9 billion years in the past.

The $2.5 billion (£1.95 billion) Mars 2020 is deliberate to launch in July 2020, and land in February 2021.
Mars 2020 is designed to land contained in the crater and acquire samples that may finally be returned to Earth for additional evaluation.
Nasa says a second mission might want to fly to the planet and return the samples, maybe by the later 2020s.
