First, a NASA rover would land on Mars in a spot that when was doubtlessly liveable—later decided to be Jezero Crater. It might zip about, search for layered rocks of the type that you simply’d discover in lakes and riverbeds, extract cores of them, and cache them in sealed containers. Then a second NASA spacecraft would land on Mars, obtain the rover’s pattern tubes (in one in every of a number of other ways), and switch the samples to a rocket that may launch them into Martian orbit. A European-provided orbiter would catch that rocket like a baseball glove earlier than returning residence and dropping the rocks into Earth’s ambiance, the place they might be guided, through parachute, to eagerly awaiting scientists no later than the mid-2030s.

“Put merely, that is essentially the most scientifically cautious pattern assortment mission attainable, performed in one of the vital promising locations on Mars to search for indicators of previous life,” says Jonathan Lunine, the chief scientist at NASA’s Jet Propulsion Laboratory in California. “And, in fact, ought to proof of life be discovered within the sediments, that may be an historic discovery.”
It received off to an auspicious begin. On July 30, 2020, within the throes of the covid-19 pandemic, NASA’s Perseverance rover launched atop a rocket from Florida’s Cape Canaveral. The NASA administrator on the time, Jim Bridenstine, didn’t mince phrases: “We’re in extraordinary occasions proper now,” he instructed reporters, “but now we have the truth is persevered, and now we have protected this mission as a result of it’s so essential.”
However simply earlier that very same month, the mission to Mars had became a race. China was now prepping its personal pattern return spacecraft.
And that’s when issues for MSR began to unravel.

China was comparatively late to develop a aggressive house program, however as soon as it started doing so, it wasted no time. In 2003, it first despatched one in every of its astronauts into house, through its personal bespoke rocket; within the 20 years since, it has launched its personal house station and despatched a number of uncrewed spacecraft to the moon—first orbiters, then landers—as a part of its Chang’e Challenge, named after a lunar goddess.
However an actual turning level for China’s interplanetary ambitions got here in 2020, the identical yr as Perseverance’s launch to Mars.
That December, Chang’e-5 touched down within the moon’s Ocean of Storms, a realm of frozen lava 1,600 miles lengthy. It grabbed some 2-billion-year-old rocks, put them in a rocket, and blasted them into the firmament. The samples had been captured by a small orbiting spacecraft; crucially, the thought was not all that dissimilar from how MSR imagined catching its personal samples, baseball-glove model. China’s lunar haul was then dropped off again on Earth simply earlier than Christmas. It marked the primary time since 1976 that samples had been returned from the moon, and the mission was seamless.
