NASA/ESA revise plan to recover Perseverance core samples from Mars
NASA and ESA yesterday announced that the agencies have revised their plan to recover Perseverance core samples from Mars, dropping the launch of a rover to pick up the samples.
Instead, they have decided to use Perseverance to bring the samples to the return vehicle, which will also carry two small helicopters.
In 2030, if all goes as planned, the NASA lander will touch down near where Perseverance is working. The rover will drive over to the lander, and an ESA-built robot arm will extract the tubes one by one and place them inside a spherical container the size of a basketball. In early 2031, a rocket on the lander will loft the container into Mars orbit, where a return craft built by ESA will snare it, enclose it in several layers of shielding for safety, and then head for home. In 2033, a saucer-shaped descent pod will carry the samples down to the Utah desert.
If Perseverance gets into difficulties during its 9-year wait for company, controllers can instruct it to drop its cargo of sample tubes onto the ground, creating a second depot. If that happens, the helicopters come into play: they can fly up to 700 meters, land next to a sample tube—each weighs up to 150 grams—and, with wheels on the bottom their feet, roll over the tube and pick it up with a grabber. On returning to the lander, they will drop the tubes on the ground for the arm to pick up.
The change means that the rover the United Kingdom was planning to build will either be abandoned, or repurposed as a lunar rover.

Please consider supporting my work here at Behind the Black. Your support allows me the freedom and ability to analyze objectively the ongoing renaissance in space, as well as the cultural changes -- for good or ill -- that are happening across America. Fourteen years ago I wrote that SLS and Orion were a bad ideas, a waste of money, would be years behind schedule, and better replaced by commercial private enterprise. Only now does it appear that Washington might finally recognize this reality.
In 2020 when the world panicked over COVID I wrote that the panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Only in the past year have some of our so-called experts in the health field have begun to recognize these facts.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.

The rate things are going, I expect the samples will be someday be shown in a museum… on Mars, having never left the planet.
Why not just ask Elon to put them in his return baggage? Faster and cheaper.
Reminds me of when I was a kid I attended a presentation by a brand-new astronaut of the anticipated risks of the upcoming Apollo program. At the time the Surveyor program, designed to test the lunar surface for the humans to follow, was woefully behind schedule. This wise guy said the biggest danger he saw for the first lunar landing crews was being hit by a descending Surveyor lander! His boss, who was also there, was not amused.
True story, but I cannot actually recall the guy’s name!
This seems a bit insane to me. They didn’t have this planned out before they started planning the gathering of samples? “How are we going to get them back?” “Don’t worry about it; we’ll figure it out, later.” doesn’t seem like a very professional conversation.
2030 is both a long way away and very close. If it’s going to be on Mars in 2030, it will launch in 2028/9, which means the robot arm and helicopters need to be built by early 2027, so they can be tested and refined in 2027/28. “Early 2027” is less than five years away. Are these things even designed? Just slapping a robot arm and wheels onto the Ingenuity design seems a bit risky.
