The CubeSats, named MarCO-A and B, are an experiment to check the suitability of pint-size craft for exploration of the photo voltaic system; beforehand they’ve solely ever been deployed into orbit.
That modified on Could 5, when the Perception 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 digital camera connected to the chassis had an eye fixed on the method and took a picture to send back home and inform mission management that each one was nicely.
However as a bonus (although not accidentally — 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 model 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 a giant milestone. Each our CubeSats are wholesome and functioning correctly. We’re trying ahead to seeing them journey even farther.”
Up to now it’s solely excellent news and validation of the concept that low-cost CubeSats might probably be launched by the dozen to undertake minor science missions at a fraction of the price of one thing like Perception.
Don’t anticipate any extra snapshots from these guys, although. A JPL consultant advised me that the cameras have been actually solely included to verify the antenna deployed correctly. Actually any photos of Mars or different planets in all probability wouldn’t be value twice — these are utility cameras with fisheye lenses, not the particular devices that orbiters use to get these nice planetary photographs.
The MarCOs will go by Mars on the identical time that Perception is making its touchdown, and relying on how issues go, they could even have the ability to go on a bit of helpful data to mission management whereas it occurs. Tune in on November 26 for that!
