On Dec. 12, 2023, NASA’s Perseverance rover reached a milestone — 1,000 Martian days, or sols, on Mars. To have a good time, NASA launched a 360-degree mosaic of the rover’s present location, in addition to a video walkthrough of the scene narrated by way of Perseverance undertaking scientist Ken Farley.The composite symbol contains 993 person photographs excited about Perseverance’s Mastcam-Z software remaining 12 months on Nov. 3, Nov. 4 and Nov. 6, and features a whopping 2.38 billion pixels. You could realize there is a large distinction in colour between the group’s symbol integrated on this article and the video — the picture displays the herbal colours on Mars as captured by way of the digicam, whilst the picture within the video has been adjusted to Earth-like lighting fixtures. In line with NASA, “the adjustment permits venture scientists to make use of their on a regular basis revel in to interpret the panorama.”That panorama is Jezero Crater, the place a river had flowed into an historic lake an estimated 3.5 billion years in the past. Along with learning the geology of the crater, scientists are in search of previous indicators of microbial lifestyles.

One bizarre rocky outcropping has piqued the hobby of the group, which suspects it will constitute the remnants of an outdated lava go with the flow. “Lab apparatus on Earth can appropriately measure when a volcanic rock used to be shaped, so if we will go back a pattern of this lava to Earth one day, we might know when and for a way lengthy water flowed into Jezero,” Farley says within the video.Prior to now, Perseverance studied the crater flooring ahead of operating its method during the sediments of the river delta. Subsequent, it is going to paintings its method “upstream” to the purpose the place the river carved a canyon within the crater rim. Then, Perseverance will climb its method up a herbal ramp to the rim itself. “One tempting goal are those light-colored rocks partway up the rim,” says Farley. “They will have interacted with scorching water in a hydrothermal atmosphere – every other thrilling position to seek for proof of previous lifestyles.”
