See Mars’s beautiful Jezero Crater from the air in flyover video

If you’re feeling in need of some travel to broaden your horizons but you don’t have the option to leave home right now, the European Space Agency (ESA) has something special to offer you: A virtual flight over the famous Jezero Crater on Mars.

Visit Jezero Crater on Mars in this flyover created using orbiter data

The video, created using computer simulations from data collected by ESA’s Mars Express and NASA’s Mars Reconnaissance Orbiter, begins in orbit and shows a soothing swoop down to Jezero’s location, before switching to a point of view slightly above the surface to show you the view of the crater from above. First you see a pan around the entire crater, then the video goes closer to show the features of the crater in more detail.

You’ll then see some of the most important features in the crater: a long, winding outlet channel where water once flowed out of the crater, then two inlet valleys called Neretva Vallis and Sava Vallis. The reason the outlet channel is so important is to do with how long water was present in this location.

To look for evidence of ancient life, we want to look in locations where liquid water was present. But when we do see evidence that there used to be water in an area, it’s hard to tell how long that lasted. Did the crater only fill with water once, or just very occasionally? Or was it regularly full of water, making it much more hospitable to potential emerging life? Most of the time, we can’t tell which of those is the case. But when it comes to Jezero, we know it must have been full of water for a pretty long time, because the water overflowed and carved out the outlet valley.

It’s pretty rare to have a crater with an outlet valley, and it makes Jezero a particularly good place to search for evidence of life if it ever existed on Mars.

The inlet valleys are exciting as well, as one of them meets the crater edge and then branches out to become a river delta. The NASA Perseverance rover is currently on its way to study this delta, where it should find layers of sediment from different times as well as potentially finding a wide variety of rocks, carried to this location by ancient rivers.

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.

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.

How Europe’s ExoMars rover plans to get to Mars without Russia
ESA’s Rosalind Franklin twin rover is back on its wheels and drilled down 1.7 metres into a martian-like ground in Italy – about 25 times deeper than any other rover has ever attempted on Mars. The test rover, known as Amalia, also collected samples for analysis under the watchful eye of European science teams.

Space missions get scuppered for all kinds of reasons, from engineering problems to budget issues. But the ExoMars mission, Europe and Russia's joint plan to send a rover to Mars, faced a complicated political and ethical issue when Russia invaded Ukraine last year. The European Space Agency (ESA) had been working with the Russian space agency Roscomos on the mission but this partnership was soon suspended over what ESA called the "human casualties and tragic consequences of the aggression towards Ukraine."

Without Roscosmos, the Rosalind Franklin rover was left without a launcher and it was not clear whether the rover would be able to launch at all. But loath to give up on the project, ESA decided it would build its own lander and get the rover to Mars hopefully by 2030. This week, ESA shared more information about the plans for the mission and how it is continuing with testing for the rover.
