MarCO cubesats almost failed just before InSight landing

According to a report by one of its engineers, contact was lost with the two MarCo cubesats just prior to InSight’s landing on Mars, and was recovered just in time.

The team spent all day looking at the fault tree to fix the issue, Klesh recalled. “At 6:05 a.m. [California time] the next morning, MarCO-B shows up just on time,” apparently recovering automatically from an attitude-control issue, Klesh said. He proudly told mission managers at 6:30 a.m. that both cubesats were ready to go.

But then, “45 minutes later,” he said, “MarCO-A disappeared.”

At that point, it was too late to make any changes. JPL had already sent its last commands to InSight and MarCO through NASA’s Deep Space Network (DSN) of telescopes that communicate with spacecraft far out in the solar system. So the engineers could only watch and wait. “We didn’t know what was going to happen [during landing] in a few hours’ time,” Klesh said.

Luckily for the team, MarCO-A (and its twin) both popped into communications at 12:14 p.m. and succeeded in relaying data from the InSight touchdown, sending back valuable information about the dangerous entry, descent and landing phase to NASA engineers to plan for future missions.

They have traced the issue of MarCo-A’s disappearance to being blinded by the light from Mars, thus confusing its star tracker. That both spacecraft auto-recovered when contact with Earth was lost however is I think a fine testament to their design.

Pioneer cover

From the press release: From the moment he is handed a possibility of making the first alien contact, Saunders Maxwell decides he will do it, even if doing so takes him through hell and back.

 
Unfortunately, that is exactly where that journey takes him.

The vision that Zimmerman paints of vibrant human colonies on the Moon, Mars, the asteroids, and beyond, indomitably fighting the harsh lifeless environment of space to build new societies, captures perfectly the emerging space race we see today.

He also captures in Pioneer the heart of the human spirit, willing to push forward no matter the odds, no matter the cost. It is that spirit that will make the exploration of the heavens possible, forever, into the never-ending future.
