NASA’s Perseverance rover has one final review to pass before launch to Mars

NASA’s Perseverance rover is almost certified as ready for its trip to Mars, launching on Thursday, July 30. This week, the rover passed its Flight Readiness Review. The next hurdle for the project is the final Launch Readiness Review which will take place on Monday, July 27.

The Launch Readiness Review will check whether all of the hardware is ready for the launch itself, giving final approval for the launch to go ahead. After this review concludes, NASA will hold a conference to announce its results.

Getting NASA’s Perseverance Mars Rover to the Launch Pad

This launch represents the best opportunity yet to discover evidence of ancient life on Mars and is the culmination of years of work including several difficult months during the pandemic.

To prepare the rover for its launch, it was previously stacked with the Ingenuity helicopter, in a process during which the helicopter was placed on top of the rover and both vehicles were tucked inside a shell along with a parachute to help slow their descent during the Mars landing. The vehicles will land with the assistance of a descent stage, using a system called skycrane which was first used for landing Curiosity, Perseverance’s sister rover.

The rover, helicopter, and decent stage were then transported across the country from California to Florida, where they were enclosed within the nose cone or fairing of the Atlas V rocket which will be used for the launch. With all these steps complete, the final review will certify that everything is safe and ready for launch.

“We’re pleased to be passing another milestone with the completion of the Flight Readiness Review,” Matt Wallace, deputy project manager for the mission at NASA’s Jet Propulsion Laboratory, said in a statement this week. “But we’ll keep our heads down through the final prelaunch activities and the opening of the launch window next week, until we’re certain this spacecraft is safely on its way. Mars is a tough customer, and we don’t take anything for granted.”

Perseverance rover collects its first sample from Jezero delta
This image shows the rocky outcrop the Perseverance science team calls Berea after the NASA Mars rover extracted a rock core and abraded a circular patch. The image was taken by the rover's Mastcam-Z instrument on March 30, 2023.

Things are heating up on Mars, as the Perseverance rover begins its new science campaign. In its previous science campaign, the NASA rover explored the floor of the Jezero crater, but now it has moved on to investigate an exciting location called the delta. As the site of an ancient river delta, this region is a great location to search for evidence of ancient life and to find rocks carried from far-off locations by the river that was there millions of years ago.

Perseverance collected its first sample of this science campaign last week, on Thursday, March 30. This is the 19th sample of rock and dust that the rover has collected so far, with 10 of those samples carefully left behind in a sample cache on the Martian surface. The latest sample was collected from a rock named "Berea" which is thought to be made up of deposits that were carried by the river.

NASA’s plucky Mars helicopter, Ingenuity, is about to embark on its 49th flight on the red planet.

The diminutive drone-like aircraft arrived on Mars with the Perseverance rover in February 2021.

Perseverance and Ingenuity play a game of tag across Mars
Perseverance looks towards the Delta on Sol 419, capturing this image with its Right Navigation Camera.

The Perseverance rover is currently trundling its way across Mars' Jezero Crater, on its way to explore an exciting location called the delta. It's the site of an ancient river delta, and scientists are looking forward to scouring this area for two particular reasons: firstly, because if there ever was life on Mars, then this is one of the most likely locations we could find evidence of it, and secondly, because it should be possible to find rocks from miles away that were carried to this location by the river long ago.

But it takes a long time for a little rover to travel across Mars' rocky surface, so Perseverance has been making slow progress as it makes the climb up the delta and toward the river deposits the scientists are so interested in. Now, though, the rover has a sidekick to help it, as the Ingenuity helicopter has arrived to join the rover and scout ahead to find the best path forward.
