NASA’s Mars 2020 rover will stay on Earth a little longer than expected

NASA is delaying the launch of its Mars-bound Perseverance rover by three days.

The space agency said on Thursday, June 11, that it has selected July 20 as the new launch date, scrubbing the original July 17 date. Assuming there are no further changes, the United Launch Alliance (ULA) rocket carrying the rover will lift off at 9:15 a.m. ET from Cape Canaveral in Florida.

NASA said it was prompted to delay the Mars mission because additional time was needed to carry out repairs on some ground system equipment. The space agency didn’t offer further details, but ULA president and CEO Tory Bruno, whose Atlas V rocket will transport Perseverance, later tweeted that the problem had involved a crane, adding that everything was now in order.

The mission’s launch window lasts until August 11, so the three-day delay is unlikely to cause any concern among the team.

News of the delay came via a tweet from the rover’s personal Twitter account:

The much-anticipated Mars 2020 mission will involve Perseverance exploring the Martian surface for signs of ancient life. The six-wheel machine, which has been thoroughly tested ahead of its Mars expedition, will also collect rock and soil samples for a possible return to Earth.

The Mars Helicopter will be joining Perseverance on its adventure and, assuming everything goes to plan, will become the first-ever aircraft to fly on another planet. The Mars Helicopter will help NASA to find potentially useful research sites on the Martian surface, and also gather data for mapping routes for future Mars rovers.

Space fans certainly have a lot to look forward to, but patience is required. Perseverance and the Mars Helicopter won’t reach the planet until February 2021.

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 eyes another flight record
Mars helicopter

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.

It’s been 2 years since the Perseverance rover landed on Mars
This image of the floor of Jezero Crater was taken by one of the Navcam imagers aboard NASA’s Perseverance Mars rover on Feb. 5, the 698th Martian day, or sol, of the mission.

Today marks the second anniversary since the rover Perseverance landed on the surface of Mars on February 18, 2021. The nail-biting descent and landing process was followed around the world, and was particularly memorable because of the spectacular video taken from both the rover and its descent stage showing the touchdown onto the red planet.

In the two Earth years since Perseverance arrived on Mars, it has collected samples of rock and built a sample depot, deployed the Mars helicopter Ingenuity, created oxygen from the carbon dioxide atmosphere, recorded the sounds of Mars for the first time, trundled along the floor of the Jezero crater and made its way toward the site of an ancient river delta, and taken some stunning images.
