Skills that can aid humanity land heavy hardware on Mars will glean an in-dwelling take a look at early next week.
A United Commence Alliance (ULA) Atlas V rocket is scheduled to commence the Joint Polar Surveyor System-2 (JPSS-2) weather satellite from California’s Vandenberg Space Force Impolite early Tuesday morning (Nov. 1).
JPSS-2 — a U.S. National Oceanic and Atmospheric Administration craft that can aid researchers enhance weather forecasts and show screen the impacts of climate change, amongst diversified initiatives — is no longer the largest payload onboard the Atlas V. Moreover going up on Tuesday is the Low-Earth Orbit Flight Take a look at of an Inflatable Decelerator (LOFTID) craft, a technology demonstrator whose functions may perchance presumably lengthen beyond our home planet.

A brand unique glean of landing gear
LOFTID is an expandable aeroshell, a form of warmth protect that engineers are eyeing for missions to the Crimson Planet. The skinny Martian ambiance makes landing there tricky; incoming spacecraft uncover some toddle, but no longer simply about as primary as they if fact be told feel in Earth’s air.
So it takes more than parachutes to glean payloads down safely on Mars. NASA’s golf-cart-sized Spirit and Quite numerous rovers, as an instance, also employed bouncy air baggage that cushioned their tumble. And the agency developed a rocket-powered sky crane to land its Curiosity and Perseverance rovers, each and each of that are about the dimensions of an SUV and weigh roughly 1 ton (here on Earth, anyway; they’re lighter on Mars, where the outside gravity is precise 40% as solid as our planet’s).
These missions excellent primary maxed out the weight limits of the sky crane, nonetheless. New entry, descent and landing tech may perchance be desired to glean clear-heavy payloads — habitat modules for a future look at injurious, for occasion — safely down on Mars, NASA officers hang wired.
Expandable aeroshells are one which you may perchance imagine resolution. These saucer-love buildings are designed to compress tightly enough to commence aboard historical rockets. However they inflate severely upon arrival at their planetary destination, potentially providing enough atmospheric toddle to aid land objects intention more massive than Perseverance or Curiosity. (Decelerators are no longer the total resolution; parachutes would composed be share of the idea as effectively.)
The $93 million LOFTID mission started precise five years ago, but the classic idea goes intention aid.
“The customary belief if fact be told comes from the ’50s and ’60s,” Joe Del Corso, LOFTID mission manager at NASA’s Langley Look at Heart in Virginia, said at some stage in a press convention earlier this month. “Unfortunately, at some stage in that time, they did now not hang the supplies or buildings; they were no longer sufficiently advanced enough to if fact be told label the functionality.”
NASA has completed ground and atmospheric tests with expandable aeroshells, including a 2015 trial that carried one high into the skies above Hawaii aboard a broad balloon. (That take a look at did now not mosey based mostly totally on idea, nonetheless; the supersonic parachute attached to the aeroshell ripped apart at some stage in the descent.)
However LOFTID will lift the testing to a brand unique stage.
“Or no longer it’s miles the first low Earth orbit flight take a look at of this technology, and the largest-scale take a look at article to this point,” Trudy Kortes, director of technology demonstrations at NASA’s Space Skills Mission Directorate, said at some stage in the press convention.

The flight idea
LOFTID is packed tightly internal a fetch 7.4 toes substantial and 4.3 toes wide (2.3 by 1.3 meters). It sits below JPSS-2 on the Atlas V’s Centaur upper stage.
The Centaur will deploy JPSS-2 into a sun-synchronous polar orbit about 28 minutes after liftoff on Tuesday, then maneuver its intention onto a re-entry path. Seventy-five minutes into the flight, the Centaur will commence LOFTID, which is intriguing to head aid down to Earth.
The aeroshell will hang expanded to its plump width of 19.7 toes (6 m) by this point. LOFTID will barrel thru our ambiance, experiencing most temperatures spherical 2,600 levels Fahrenheit (1,400 levels Celsius) before deploying parachutes and splashing down softly in the Pacific Ocean shut to the Hawaiian islands.
Mission workers participants will pore over the concepts LOFTID gathers on the vogue down, the exercise of it to spherical out their working out of expandable aeroshells’ capabilities and ability. That ability is spirited, and it’s no longer at all times slight to Crimson Planet missions, Kortes said.
“This technology can after all enable unique missions for us to Mars [and] Venus; even the largest moon of Saturn, Titan, turns into a probability on chronicle of the dense ambiance there,” she said. “And it may perchance maybe maybe additionally be outdated for payload returns to Earth as effectively.”
ULA is especially in that return-to-Earth perspective. The commence firm is partnering with NASA on LOFTID, below an unfunded Space Act Agreement, because it wants to assess the that you may perchance imagine exercise of decelerators on missions of its future Vulcan Centaur rocket, the successor to the Atlas V.
ULA wants to reuse the Blue Starting place BE-4 engines that vitality Vulcan Centaur’s first stage, and expandable aeroshells love LOFTID most continuously is a correct technique to glean this precious hardware safely aid to Earth.
“All of the concepts we glean out of the LOFTID mission may perchance be outdated to aid correlate objects and uncover a substantial better working out of what the Vulcan reuse machine will face,” James Cusin, an operations engineer in ULA’s Developed Programs division, said in an announcement (opens in unique tab).
