Within the span of simply six days, NASA took two huge 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 response to plan, the 2 automobiles will even 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 protect 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, workforce members stated.
“The demonstration was an enormous success,” Joe Del Corso, LOFTID mission supervisor at NASA’s Langley Analysis Heart in Virginia, stated throughout a press convention on Thursday (Nov. 17).
“We now have now the flexibility to each put heavy payloads into space and to deliver them again down,” he added. “These two successes are enormous steps in enabling human entry and exploration. We will space, and we wish to have the ability to keep there.”
LOFTID (quick for “Low-Earth Orbit Flight Check of an Inflatable Decelerator”) is an inflatable warmth protect designed to gradual a payload’s descent by way of a planetary environment by way of drag.
NASA deems this technique a promising one for its crewed Mars plans, which would require touchdown huge payloads similar to habitat modules on the Pink Planet. Such gear might tip the scales at 20 tons or so — far too heavy for present Mars entry, descent and touchdown methods to deal with.
NASA’s 1-ton Curiosity and Perseverance Mars rovers, for instance, just about tapped out the rocket-powered sky crane methodology that acquired them down safely by way of the Pink Planet’s skinny air, company officers have stated. (Parachutes had been a part of these rovers’ touchdowns as nicely, as they might be with an inflatable warmth protect 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 toes (6 meters), positioned itself for Earth return and took the plunge.
Preliminary inspections, carried out after the warmth protect was pulled out of the Pacific Ocean close to Hawaii, urged 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 lovely. It appears to be like pristine, and I actually cannot say that sufficient,” Del Corso stated. “It was stunning to me how nicely, how good, the automobile seemed.”
Scientists and engineers will proceed analyzing information for one more yr or so to get a whole understanding of the check flight, LOFTID workforce members stated.
The LOFTID mission, which value 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 Pink Planet, mission workforce members stated. Scaling the tech up so dramatically poses plenty of challenges, which scientists and engineers can now begin assessing significantly after LOFTID’s profitable flight.
“There’s fairly a bit of labor that must be carried out with that [scaling up]; there are facility issues with that that must be checked out,” Trudy Kortes, director of expertise demonstrations at NASA’s House Know-how Mission Directorate, stated throughout Thursday’s briefing.
“However the roadmap will information us on that and our future investments in that,” she added. “We’re looking at that now, and actually the short-term future for that. So yeah, that might be the following step for this functionality.”
