A tiny satellite bound for Mars just snapped a picture that makes the red planet look puny and insignificant
- NASA's InSight Mars lander launched on May 5 and will reach the red planet on November 26.
- But two small satellites, collectively called Mars Cube One, are also nearing the world.
- One of these backpack-size "CubeSat" spacecraft recently took a photo of Mars from 8 million miles away.
- Mars glows bright red-orange in the picture, but the world also looks incredibly small - and even conquerable.
Mars is a sizable planet about nine times the mass of our moon. The latest scientific research also suggests Mars, despite looking like a giant desert, may harbor enough subsurface water and warmth to support microbial life today.newly released image taken by a tiny satellite that's closing in on Mars.
The picture was taken from about 8 million miles away by one of two backpack-size CubeSats, collectively known as Mars Cube One, or MarCO.
The two satellites - MarCO-A and MarCO-B, nicknamed by their creators "EVE" and "Wall-E," respectively - launched on May 5. They hitched a ride with NASA's much-larger, car-size InSight lander, which is scheduled to land on Mars on November 26.
The MarCO satellites are officially the smallest spacecraft ever flown past the moon. They're also a crucial test for NASA to see how small it can shrink its spacecraft, and how far it can send them into the solar system.
Until then, MarCO's systems are being intermittently tested. On October 2, MarCO-B swung Mars into view during camera, rotation, and communications test and snapped the photo below.
"We've been waiting six months to get to Mars," Cody Colley, who manages the MarCO mission for NASA's Jet Propulsion Laboratory, said in a press release. "The cruise phase of the mission is always difficult, so you take all the small wins when they come. Finally seeing the planet is definitely a big win for the team."
The picture was taken from 8 million miles away - cosmically close, since the red planet is an average of 140 million miles from Earth.
Yet Mars still looks like an infinitesimal red dot in the image. (The objects on the periphery are parts of the spacecraft.)
Previously, the MarCO team honored Carl Sagan's "Pale Blue Dot" image by using MarCO-B to photograph Earth from 621,371 miles away. Earth looked similarly feeble in that image.
On the flipside, the image shows Mars is not an infinite plane like the rest of the universe.To someone like Elon Musk, who is trying to use his rocket company, SpaceX, to build a giant reusable spaceship capable of reaching the red planet, the picture might make Mars look that much more conquerable.
