NASA Perseverance Rover Captures 152-image Mosaic of Belva Crater

NASA’s Perseverance Mars rover recently captured a series of 152 images while investigating the Belva Crater which NASA has stitched into a dramatic and striking mosaic.

The Belva Crater is a large impact crater within the much larger Jezero Crater. The Belva Crater interests scientists because it delivers a view of vertical cuts of rocks and sediment on Mars.

“Mars rover missions usually end up exploring bedrock in small, flat exposures in the immediate workspace of the rover. That’s why our science team was so keen to image and study Belva. Impact craters can offer grand views and vertical cuts that provide important clues to the origin of these rocks with a perspective and at a scale that we don’t usually experience,” explains Katie Stack Morgan, deputy project scientist of Perseverance at NASA’s Jet Propulsion Laboratory in California.

“This view of the interior of Belva Crater was generated using data collected by the Mastcam-Z instrument aboard NASA’s Perseverance Mars rover on April 22, 2023, the 772nd Martian day, or sol, of the mission. When the 152 individual images that make up this mosaic were taken, the rover was parked at the west side of the crater’s rim, on a light-toned rocky outcrop the science team is calling ‘Echo Creek,'” NASA explains.

NASA compares the vertical cut offered by Belva Crater to highway “roadcuts” on Earth. Geology students often look at areas where construction crews have sliced vertically through rock to build roads, as these cuts allow a view of rock layers and other geological features that can’t be viewed from the surface. Belva Crater offers a similar view of Mars.

Perseverance, which landed on Mars in early 2021, has been actively investigating Jezero Crater, searching for information about ancient Mars and evidence that Mars could have supported life. Perseverance is exploring Mars in tandem with the Ingenuity Mars helicopter, which recently captured an incredible aerial photo of Mars, including a photobomb by Perseverance.

As explained by NDTV, the new photos of Mars’ Belva Crater were captured by Perseverance’s Mastcam-Z instrument.

SciNews on YouTube compiled Perseverance’s new images into the video seen below.

Belva Crater is about 0.9 kilometers wide (0.6 miles) and is one of many known craters on Mars. Only about a thousand craters are named, but there are hundreds of thousands of craters on the Martian surface that are larger than a kilometer (0.62 miles).

NASA explains that a rocky outcrop called “Echo Creek” shows signs of being a Martian sandbar.

“These ‘dipping beds’ could indicate the presence of a large Martian sandbar, made of sediment, that billions of years ago was deposited by a river channel flowing into the lake that Jezero Crater once held,” NASA writes.

The large boulders in the foreground of the mosaic image are “either chunks of bedrock exposed by the meteorite impact,” or they might have been “transported into the crater by the river system.” Ongoing investigations aim to settle the debate.

Concerning ancient rivers on Mars, Perseverance also recently captured stunning photos of bands of rocks that some scientists think may have been formed by a “very fast, deep river.” The evidence is the first of its kind on Mars, and scientists have named the location where the mosaic was captured “Skrinkle Haven.”

This is an enhanced color view of the mosaic, which is comprised of 203 individual image images. This image offers the “clearest example of these curved rock layers.”

An anaglyph, or 3D version, of the mosaic will also help.

“An anaglyph can help us visualize the geologic relationships between the crater wall outcrops. But it also provides an opportunity to simply enjoy an awesome view. When I look at this mosaic through red-blue 3D glasses, I’m transported to the western rim of Belva, and I wonder what future astronauts would be thinking if they were to stand where Perseverance once stood when it took this shot,” Stack says.

This image, called an anaglyph, can be viewed with red-blue 3D glasses.

Perseverance will continue investigating the area around Jezero Crater as part of its astrobiology mission. “The rover will characterize the planet’s geology and past climate, pave the way for human exploration of the Red Planet, and be the first mission to collect and cache Martian rock and regolith,” NASA says of the Perseverance mission.
