7, 2021.įor a long time – potentially millions of years – a river flowed into a lake that filled Jezero Crater. Toward the top we spotted boulders, some as large as 5 feet (1.5 meters) across.įrom the structure of these formations, our team has been able to reconstruct a geological story billions of years old, which we published in the journal Science on Oct. When the images got back to Earth, we saw tilted layers of sediments in the lower parts of the 260-foot-tall (80 meters) cliffs.

From those panoramic views, we selected specific spots to look at in more detail with the rover’s SuperCam, a telescopic camera. During the first few weeks of the mission, we used Mastcam–Z to survey the distant rocks. We are both on the team in charge of the Mastcam-Z instrument, a set of cameras with zoom lenses that would allow us to see a paper clip from the opposite side of a football field. Perseverance landed over a mile (roughly 2 kilometers) away from the cliffs at the front of the delta. This structure of boulders and sediment shows the geological history of the delta.

These images are helping the team decide how to navigate around obstacles on the way toward the rover’s eventual destination, a large delta in Jezero Crater. Ingenuity has now flown 13 times and has captured detailed photos of the ground to scout out the rough terrain ahead of Perseverance. The next flights tested the helicopter’s ability to move horizontally, and it covered longer distances each time, traveling as much as 2,050 feet (625 meters) in its farthest trip to date. This short hop showed that its long blades could generate enough lift to allow flight in Mars’ thin air. On April 19, 2021, the helicopter took its first flight, hovering 10 feet (3 meters) above the ground for 39 seconds before coming straight down. Ingenuity is solar powered, weighs 4 pounds (1.8 kg), and its main body is roughly the size of a grapefruit. The Ingenuity helicopter detached from the rover shortly after they landed on Mars and became the first craft to fly in the atmosphere of another planet. Perseverance may be a long way from Earth, but it has a sidekick. Ingenuity’s first flight, seen in this video, showed that the helicopter could fly on Mars. We found crystalline minerals that suggest the rocks formed in a basaltic lava flow, as well as salt minerals that could be evidence of ancient groundwater. At both sites, Perseverance used the SHERLOC and PIXL spectrometers on its arm to measure the composition of the rocks. NASA’s Mars Sample Return mission, which is currently in development, will pick up the sample tubes in the late 2020s and bring them home.īut scientists don’t have to wait that long to learn about the rocks. After collecting up to a few dozen more, it will drop the samples at a safe and easily accessible location on Mars’ surface. This time Perseverance successfully extracted and stored two core samples from the grayish, wind-polished rock. This suggested that the rocks were harder and therefore easier to take a sample of. Three weeks and 1,800 feet (550 meters) later, we came across some promising-looking rocks protruding up above the red surface. Ultimately, our team concluded that the rock itself was much softer than expected and it was completely pulverized during the act of drilling. Some of Mars’ atmosphere is trapped inside and will be useful to study, but it’s not what the team was hoping for.

However, the next day the rover sent photos of the inside of the tube, and we saw it was actually empty. After six days of assessing the bedrock – and finally drilling into it – we were thrilled to see a hole in the ground and get confirmation that the sample tube had sealed successfully. A future mission will then pick them up and bring them on a long, interplanetary journey back to Earth.įor Perserverance’s first drilling attempt in August, our team picked a nice flat rock that was easy to access with the drill. One of Perseverance’s primary objectives is to use its sample caching system to extract small rock cores – roughly the size of dry-erase markers – and seal them in special sample tubes. Perseverance has already cached two samples of Martian rocks after drilling cores out of a rock, the first of which is the hole seen here.
