NASA’s Curiosity Rover Found A Strange Metallic Object on Mars
NASA’s Curiosity rover recently stumbled upon an unusually shiny object in Mars’ Gale Crater. While the discovery received some coverage, it came at a time when most attention was focused on the space agency’s successful touchdown of the InSight Lander. NASA says it believes the object may be a meteorite and that it plans to study it more closely, though Curiosity was unable to pick it up on its first attempt.
The object, which NASA named Little Colonsay after an island in Scotland, has a distinct sheen to it, even noticeable through a black and white image the agency posted on its website.
“The planning team thinks it might be a meteorite because it is so shiny,” Susanne Schwenzer, a member of the Curiosity team, wrote. “But looks can deceive, and proof will only come from the chemistry.”
Curiosity has discovered meteorites in the past, though every irregular or eye-catching find sparks excitement, especially considering the recent discovery of a 12-mile wide body of water beneath the planet’s surface — a breakthrough confirming that Mars, at some point in its past, contained vast oceans and potentially harbored life. This possibility excites those who believe we may find evidence of a lost civilization or even fossils beneath the planet’s dusty surface.
The latest discovery apparently occurred the same day the InSight Lander touched down, as NASA’s JPL website said Curiosity was greeted by the Mr. Rogers’ jingle “Please would you be my neighbor,” before it got to work studying Little Colonsay.
This is not the first time Curiosity has come across anomalous looking objects, as it once found a piece of plastic, which was later alleged to have originated as debris from its landing.
Other strange looking objects the rover uncovered have convinced people that NASA found animals or artificial remnants it then covered up or ignored. However, the space agency insists these to be the product of pareidolia – a trick our minds play on us to make objects appear recognizable – though still, some remain skeptical.
Back in August, a very distinctly shaped object was discovered by Curiosity igniting speculation of an alien artifact or that it was a piece of the rover which was starting to fall apart. NASA tried to quell the excitement saying it tested the object and found it was a rock.
In other instances, online sleuths have claimed that the rover imaged animals including a squirrel and a duck on the Martian surface. These claims however, should probably be taken with a grain of salt, but if you’re interested you can find them here and here.
Even if most of Curiosity’s discoveries are just rocks, there are in fact, some truly unexplained anomalies discovered while observing the red planet – check them out in this episode of Deep Space :

Scientists Now Say Interstellar Object May Have Been Alien Probe
Harvard scientists reexamined the bizarre, interstellar space object known as “Oumuamua,” which rocketed through our solar system late last year, resurrecting the possibility that it may be an alien probe. Academics and scientists were quick to write off the cigar-shaped object as a previously unknown type of bolide – a comet or asteroid – propelled in a highly unusual manner, but their observations are once again, being challenged.
Oumuamua, which means “a messenger sent to reach out in advance,” was first observed by Robert Weryk at the Pan-STARRS 1 telescope in Hawaii. He measured the object to be several hundred meters in length, or the size of a large sports stadium.
The size and shape of the object were calculated to be able to hold up to collisions with space dust and debris while maintaining enough momentum to travel the vast distance between stars, but recent examinations found a discrepancy in its mass-to-area ratio that doesn’t quite add up.
“Known solar system objects, like asteroids and comets, have mass-to-area ratios orders of magnitude larger than our estimate for ‘Oumuamua,” said Shmuel Bialy and Abraham Loeb of the Harvard Smithsonian Center for Astrophysics.
“If radiation pressure is the accelerating force, then ‘Oumuamua represents a new class of thin, interstellar material, either produced naturally, or of an artificial origin.”
They went on to speculate about the possibility of Oumuamua as a type of artificial satellite known as a lightsail, which is currently in development by the Breakthrough Initiative program founded by Yuri Milner and Stephen Hawking. Loeb is a member of the Breakthrough Starshot Initiative.
“The lightsail technology might be abundantly used for transportation of cargos between planets or between stars. In the former case, dynamical ejection from a planetary system could result in space debris of equipment that is not operational anymore and is floating at the characteristic speed of stars relative to each other in the Solar neighborhood. This would account for the various anomalies of ‘Oumuamua, such as the unusual geometry inferred from its lightcurve,” Bialy and Loeb said.
Oumuamua hurdled through our solar system at 58,000 mph when it was discovered on Oct. 19, 2017. The object was then propelled by the Sun’s gravity, causing it to blast off on a hyperbolic trajectory out of our solar system at a rate of 196,000 mph.
This exit speed was initially attributed to a combination of a gravity assist from the Sun and outgassing – the release of gasses from a comet as its surface heats. But scientists noticed that Oumuamua didn’t show the typical “coma,” or cloud of gas, one might expect from an outgassing comet, making its high escape velocity especially strange.
This led Loeb and Bialy to consider another potential for Oumuamua… a more exciting one.
“Alternatively, a more exotic scenario is that ‘Oumuamua may be a fully operational probe sent intentionally to Earth vicinity by an alien civilization,” the authors said.
Unfortunately it’s way too late for us to send a probe to Oumuamua or even to photograph it so that it could be studied properly, due to simply to its sheer speed and the distance it’s already travelled from Earth. Instead, Bialy and Loeb suggest we keep our eyes out for similar objects careening through our local celestial neighborhood.
