First CubeSats to travel the solar system snap ‘Pale Blue Dot’ homage

Posted on

The InSight launch earlier this month had a few stowaways: a pair of tiny CubeSats which can be already the farthest such tiny satellites have ever been from Earth — by a protracted shot. And one in every of them acquired an opportunity to snap a picture of their residence planet as an homage to the Voyager mission’s famous “Pale Blue Dot.” It’s hardly as wonderful a shot as the unique, but it surely’s nonetheless cool.

The CubeSats, named MarCO-A and B, are an experiment to take a look at the suitability of pint-size craft for exploration of the solar system; beforehand they've solely ever been deployed into orbit.

That modified on Could 5, when the InSight mission took off, with the MarCO twins detaching on an identical trajectory to the geology-focused Mars lander. It wasn’t lengthy earlier than they went farther than any CubeSat has gone earlier than.

A number of days after launch MarCO-A and B have been about 1,000,000 kilometers (621,371 miles) from Earth, and it was time to unfold its high-gain antenna. A fisheye camera connected to the chassis had a watch on the course of and took a picture to send back home to inform mission management that each one was properly.

However as a bonus (although not by chance — only a few accidents occur on missions like this), Earth and the moon have been in full view as MarCO-B took its antenna selfie. Right here’s an annotated version of the one above:

“Contemplate it our homage to Voyager,” mentioned JPL’s Andy Klesh in a news release. “CubeSats have by no means gone this far into house earlier than, so it’s an enormous milestone. Each our CubeSats are wholesome and functioning correctly. We’re trying ahead to seeing them travel even farther.”

Up to now it’s solely good news and validation of the concept that low-cost CubeSats may doubtlessly be launched by the dozen to undertake minor science missions at a fraction of the value of one thing like InSight.

Don’t count on any extra snapshots from these guys, although. A JPL consultant advised me the cameras have been actually solely included to ensure that the antenna deployed correctly. Actually any footage of Mars or different planets most likely wouldn’t be value twice — these are utility cameras with fisheye lenses, not the particular devices that orbiters use to get these nice planetary pictures.

The MarCOs will move by Mars at the similar time that InSight is making its touchdown, and relying on how issues go, they might even have the option to move on just a little helpful data to mission management whereas it occurs. Tune in on November 26 for that!
