Curiosity has found an intriguing shiny object on the surface of Mars

NASA’s Curiosity rover project is back in action after some issues with its computer — and has discovered an intriguing shiny object on the surface of Mars.

Curiosity’s ChemCam camera has been busy snapping images of the area around the rover, and the ChemCam will be looking next at four samples in particular. Two of them have been targeted before, but scientists want to go back and look at the objects in more detail. One of the re-targeted samples is “Little Colonsay,” a shiny object that the NASA team believes may be a meteorite. Curiosity has discovered meteorites on the surface of Mars before; in 2014 it found a shiny rock thought to be an iron meteorite, and in 2015 a nickel-iron meteorite was examined.

However, it’s hard to tell what the Little Colonsay object is just from images, so the rover will need to gather a sample for chemical analysis before a judgement can be made about whether it crashed into Mars from somewhere else in space. The ChemCam tool, as the name suggests, is more than just a camera. It also allows chemical analysis using instruments like a laser and a spectrograph which can give more information about the makeup of a sample.

The other three things Curiosity is targeting are a dark object called “Flanders Moss,” which scientists are unsure what to make of without chemistry information showing its composition, and two samples of grey bedrock called “Forres” and “Eildon.”

But Curiosity won’t site idle while its ChemCam works — the rover also needs to dump the sample it collected from the Highfield drill site by swinging its arm around and out of the way so that the sample is piled nearby. The instruments onboard the rover, including the ChemCam, can then analyze the pile more clearly. Other projects for the busy rover include environmental observations, like a crater rim extinction, using the Mast Camera or Mastcam to collect color images and video including optical depth measurement, and monitoring for dust devils.

Helicopter Ingenuity will be skimming over the surface of Mars today
NASA's Ingenuity helicopter.

Intrepid Mars helicopter Ingenuity is gearing up for its 13th flight today, Saturday, September 4, in what NASA engineers hope will be a "Lucky 13." The helicopter will be skimming lower to the ground than on recent flights, capturing the Martian surface from a lower altitude to help give a different view to the drivers for its companion, the rover Perseverance.

The flight is scheduled for 8:08 p.m. ET (5:08 p.m. PT) tonight, heading over the South Seítah region -- the same region it recently explored in its risky but successful 12th flight.

NASA’s Curiosity Mars Rover Finds A Changing Landscape

NASA has shared an incredible video touring of the surface of Mars, as captured by the Curiosity rover. The rover has been exploring the Gale Crater area since it landed in 2012, and the images it has taken show the dry, lifeless environment of the planet.

Perseverance rover has problems collecting its first Mars sample
This image taken by NASA’s Perseverance rover on Aug. 6, 2021, shows the hole drilled in a Martian rock in preparation for the rover’s first attempt to collect a sample.

NASA had aimed to collect its first sample of Martian rock using the Perseverance rover yesterday, Friday, August 6, but the sampling attempt didn't go as planned. The rover failed to collect a rock sample and seal it into a tube for future analysis on Earth, but NASA officials say they're confident that they can figure out what went wrong.

Collecting samples from Mars is a major part of Perseverance's mission. The idea is that the rover will drill into the rocks in the Jezero crater area, where it is exploring, and collect a variety of samples. Each sample will be sealed in an airtight container called a sample tube. Then planned future missions to Mars will collect these samples and return them to Earth for study.
