NASA’s Perseverance rover is presently trundling throughout the floor of Mars, gathering specifically chosen samples of rock for return to Earth within the coming years by the bold Mars Pattern Return (MSR) mission.
Bringing the samples to Earth will enable scientists to research the supplies utilizing superior laboratory gear as they search to find if microbial life as soon as existed on the faraway planet.
NASA is working with the European Area Company (ESA) in a bid to launch the MSR mission towards the tip of this decade.
A part of the preparation work consists of testing the suitability of various capsule designs, one among which can carry the samples again to Earth within the last stage of the lengthy journey from Mars. The capsule should face up to excessive forces because it enters Earth’s environment, and with no parachute to sluggish its descent it’ll additionally need to be robust to smash into the bottom whereas conserving the samples intact.
“The aim of those assessments … is to know how a lot load the Mars samples will see once they influence the bottom at that top velocity,” stated NASA engineer James Corliss.
Within the video beneath, engineers are proven dropping one of many capsule designs from a tall construction on the Touchdown and Affect Analysis Facility at NASA’s Langley Analysis Heart in Virginia.
In one other check, the workforce dropped a capsule from a good increased altitude, launching it out of a helicopter over the Utah Check and Coaching Vary, which is the place mission planners are hoping to land the MSR capsule on the finish of the mission.

There’s nonetheless an enormous quantity of labor to be achieved earlier than the MSR mission will get underway. When it lastly launches, it’ll be a nail-biting time for NASA and ESA personnel as they wait to see if every stage of the retrieval effort goes in accordance with plan.
The mission from begin to end will most likely look one thing like this: First, a rocket launched from Earth will deploy a spacecraft to Mars. Because it approaches the purple planet, the spacecraft will launch a lander to the martian floor.
As soon as the lander is safely on the bottom, it’ll ship a rover to choose up the sealed samples of Mars rock left by Perseverance.
Subsequent, a small rocket will launch the gathered samples into Mars orbit, the place they are going to be transferred to a ready orbiter. The orbiter will then transport the samples to Earth, a journey that within the last stage will see the orbiter launch the capsule towards Utah.
Then it’s a case of retrieving the capsule, extracting the samples, and sending them to the lab, giving scientists their first shut take a look at an honest vary of Mars materials.
“Bringing Mars samples again to Earth will enable scientists internationally to look at the specimens utilizing subtle devices too giant and too complicated to ship to Mars, and can enable future generations to check them utilizing expertise not but accessible,” NASA stated earlier this yr. “Curating the samples on Earth will enable the science group to check new theories and fashions as they’re developed, a lot because the Apollo samples returned from the moon have achieved for many years.”
