NASA hedges its bets on expensive Mars rock mission : NPR

MARY LOUISE KELLY, HOST:

A NASA rover on Mars has been amassing samples of rock and sealing them into metallic tubes. NASA needs to launch a robotic mission that will choose up these samples and would return them to Earth. That has been a problem. NPR’s Nell Greenfieldboyce has an replace.

NELL GREENFIELDBOYCE, BYLINE: Samples of rock have been introduced again from the moon, from asteroids however by no means from one other planet. So when NASA designed the Perseverance rover, they despatched alongside tubes fabricated from titanium. The rover has been busy filling them up with samples of rocks, filth, the Martian environment. NASA needs to convey 30 of those tubes again to Earth in order that their contents could be analyzed in a safe lab. The purpose is to be taught extra concerning the historical past of the pink planet, similar to whether or not it ever had life.

BILL NELSON: We wish to have the quickest, most cost-effective solution to get these 30 samples again.

GREENFIELDBOYCE: That is NASA administrator Invoice Nelson talking at a press briefing on Tuesday. He says the unique plan to get the rocks again was turning out to be sluggish and costly. Projected prices ballooned to $11 billion, with a return date as far off as 2040.

NELSON: This factor has gotten uncontrolled.

GREENFIELDBOYCE: So final 12 months prime officers pulled the plug and hit the reset button. NASA solicited concepts from business and outdoors consultants. And now Nelson says NASA will spend a while concurrently exploring two totally different mission choices. One will depend on tried-and-true applied sciences for attending to Mars which have been utilized in earlier missions, plus simplified parts of the unique plan. The opposite possibility will benefit from rising industrial capabilities. NASA will work on the engineering for each and finally choose one.

NELSON: The ultimate choice is prone to are available in 2026.

GREENFIELDBOYCE: Planetary scientists, who’ve lengthy been wanting to convey Mars rocks dwelling, paid shut consideration to his phrases. Jack Mustard is with Brown College.

JACK MUSTARD: I am heartened to listen to the administrator say, you recognize, I can see a path ahead. I imply, I believe that is the underside line, proper? They see a path ahead.

GREENFIELDBOYCE: That was in no way assured. This sense of aid was echoed by Vicky Hamilton, a planetary geologist with the Southwest Analysis Institute, though she had been hoping to listen to what the mission would appear to be.

VICKY HAMILTON: I’m dissatisfied slightly bit that we nonetheless do not know precisely what the structure shall be.

GREENFIELDBOYCE: Nonetheless, she says NASA actually hasn’t had a lot time to consider the varied proposals it acquired from business.

HAMILTON: So I can perceive that they wish to take slightly extra time to have a look at that.

GREENFIELDBOYCE: And he or she was comfortable to listen to that NASA needs to retrieve all 30 samples moderately than making do with a smaller choice. She says these rigorously assembled samples may reveal whether or not or not Mars was ever dwelling to historic life.

HAMILTON: We’ll the best place and amassing the best samples to do the perfect job we are able to at attempting to reply that query.

GREENFIELDBOYCE: The incoming Trump administration and Congress will weigh in on all this, plus the European House Company, NASA’s companion on this effort. In the meantime, China has been pursuing its personal undertaking to gather and return a Martian rock. Nelson referred to as it extra of a grab-and-go mission. Nell Greenfieldboyce, NPR Information.
