Within the span of simply six days, NASA took two large steps towards placing boots on Mars.
The company’s Artemis 1 mission launched on Wednesday morning (Nov. 16), sending an uncrewed Orion capsule towards the moon atop an enormous Space Launch System (SLS) rocket.
NASA is relying on SLS and Orion to assist the company set up a lunar base by the tip of the 2020s — a key precedence of the Artemis program. And, if all goes in keeping with plan, the 2 autos may also allow much more formidable feats, serving to astronauts get to Mars by the late 2030s or early 2040s.

Final week, on Nov. 10, NASA examined {hardware} that might assist these crewed Mars missions land safely — an inflatable warmth defend known as LOFTID, which launched to Earth orbit with the JPSS-2 climate satellite after which got here barreling again to Earth. LOFTID survived its fiery return journey in nice form, suggesting that the tech has nice potential to assist land heavy {hardware} on Mars, group members mentioned.
“The demonstration was an enormous success,” Joe Del Corso, LOFTID undertaking supervisor at NASA’s Langley Analysis Heart in Virginia, mentioned throughout a press convention on Thursday (Nov. 17).
“We have now now the flexibility to each put heavy payloads into space and to carry them again down,” he added. “These two successes are large steps in enabling human entry and exploration. We will space, and we would like to have the ability to keep there.”
LOFTID (brief for “Low-Earth Orbit Flight Take a look at of an Inflatable Decelerator”) is an inflatable warmth defend designed to gradual a payload’s descent by a planetary environment through drag.
NASA deems this technique a promising one for its crewed Mars plans, which would require touchdown large payloads similar to habitat modules on the Purple Planet. Such gear may tip the scales at 20 tons or so — far too heavy for present Mars entry, descent and touchdown programs to deal with.Â
NASA’s 1-ton Curiosity and Perseverance Mars rovers, for instance, just about tapped out the rocket-powered sky crane technique that received them down safely by the Purple Planet’s skinny air, company officers have mentioned. (Parachutes had been a part of these rovers’ touchdowns as properly, as they might be with an inflatable warmth defend touchdown system.)
Final week’s launch offered an formidable check of this tech. LOFTID launched in a compact configuration with JPSS-2 aboard a United Launch Alliance Atlas V rocket. After deploying from the Atlas V’s Centaur higher stage, LOFTID expanded to its full diameter of about 20 ft (6 meters), positioned itself for Earth return and took the plunge.
Preliminary inspections, carried out after the warmth defend was pulled out of the Pacific Ocean close to Hawaii, advised that LOFTID handed the check with flying colours. And an additional week of analyses has solely strengthened that conclusion.
“The automobile appears to be like simply stunning. It appears to be like pristine, and I actually cannot say that sufficient,” Del Corso mentioned. “It was shocking to me how properly, how good, the automobile regarded.”
Scientists and engineers will proceed analyzing knowledge for an additional yr or so to get an entire understanding of the check flight, LOFTID group members mentioned.
The LOFTID undertaking, which price a total of $93 million over 5 years, is not the ultimate step in inflatable Mars warmth shields, nonetheless.
A construction about three or 4 instances wider than LOFTID would seemingly be required to get a giant payload like a habitat module down safely on the Purple Planet, undertaking group members mentioned. Scaling the tech up so dramatically poses quite a few challenges, which scientists and engineers can now begin assessing severely after LOFTID’s profitable flight.
“There’s fairly a bit of labor that must be achieved with that [scaling up]; there are facility issues with that that should be checked out,” Trudy Kortes, director of know-how demonstrations at NASA’s Area Expertise Mission Directorate, mentioned throughout Thursday’s briefing. Â
“However the roadmap will information us on that and our future investments in that,” she added. “We’re having a look at that now, and actually the short-term future for that. So yeah, that might be the subsequent step for this functionality.”
