Resources on Mars Could Support Human Explorers

In the coming decades, multiple space agencies and private companies plan to establish outposts on the Moon and Mars. These outposts will allow for long-duration stays, astrobiological research, and facilitate future Solar System exploration. However, having crews operating far from Earth for extended periods will also present some serious logistical challenges. Given the distances and costs involved, sending resupply missions will be both impractical and expensive. For this reason, relying on local resources to meet mission needs – aka. In-Situ Resource Utilization (ISRU) – is the name of the game.

The need for ISRU is especially important on Mars as resupply missions could take 6 to 9 months to get there. Luckily, Mars has abundant resources that can be harvested and used to provide everything from oxygen, propellant, water, soil for growing food, and building materials. In a recent study, a Freie Universität Berlin-led team evaluated the potential of harvesting resources from several previously identified deposits of hydrated minerals on the surface of Mars. They also presented estimates of how much water and minerals can be retrieved and how they may be used.

A Moon Base Will Need a Transport System

Through the Artemis Program, NASA will return astronauts to the lunar surface for the first time since Apollo 17 landed in 1972. Beyond this historic mission, scheduled for September 2026, NASA plans to establish the infrastructure that will enable annual missions to the Moon, eventually leading to a permanent human presence there. As we addressed in a previous article, this will lead to a huge demand for cargo delivery systems that meet the logistical, scientific, and technical requirements of crews engaged in exploration.

Beyond this capacity for delivering crews and cargo, there is also the need for transportation systems that will address logistical needs and assist in exploration efforts. These requirements were outlined in a 2024 Moon to Mars Architecture white paper titled “Lunar Mobility Drivers and Needs.” Picking up from the concurrently-released “Lunar Surface Cargo,” this whitepaper addresses the need for lunar infrastructure that will enable the movement of astronauts and payloads from landing sites to where they are needed the most. As usual, they identified a critical gap between the current capabilities and what is to be expected.

NASA's Skyrocketing Need for Cargo Deliveries to the Moon

NASA has big plans for the Moon. Through the Artemis Program, NASA plans to create a program of “sustained exploration and lunar development.” This will include the creation of the Lunar Gateway, an orbital habitat that will facilitate missions to and from the surface, and the Artemis Base Camp that will allow for extended stays. Through its Commercial Lunar Payload Services (CLPS) program, NASA has contracted with commercial partners like SpaceX and Blue Origin to deliver scientific experiments and crew to the lunar surface.

However, these efforts are expected to culminate in the creation of a permanent outpost and human presence on the Moon. This will require far more in the way of crew and payload services to ensure crews can be sustained in the long run. In a recent white paper, “Lunar Surface Cargo,” NASA researchers identified a significant gap between current cargo delivery capabilities and future demand. The paper indicates that this growing cargo demand can only be met by creating a “mixed cargo lander fleet.”

Astronauts are Practicing Lunar Operations in New Space Suits

Through the Artemis Program, NASA will send astronauts to the lunar surface for the first time since 1972. While the challenges remain the same, the equipment has evolved, including the rocket, spacecraft, human landing system (HLS), and space suits. In preparation for Artemis III (planned for September 2026), NASA recently conducted a test where astronauts donned the new space suits developed by Axiom Space and practiced interacting with the hardware that will take them to the Moon.

Starliner Finally Launches, Carrying Two Astronauts Into Orbit

After many delays and two scrubbed launch attempts, Boeing’s CST-100 Starliner successfully launched earlier today! The Crewed Flight Test (CFT) took off from Space Launch Complex-41 at Cape Canaveral Space Force Station, Florida, at 10:52 a.m. EDT (07:52 PDT) atop a ULA Atlas V rocket. For this mission, the capsule is carrying two NASA astronauts: Barry “Butch” Wilmore (commander) and Sunita “Suni” Williams (pilot). They are expected to reach the International Space Station (ISS) at 12:15 p.m. EDT (09:15 a.m. PDT) on Thursday, June 6th.

Back in December, NASA officials, space industry experts, members of the academic community, and science communicators descended on Washington, D.C., for the Achieving Mars Workshop X (AM X). This workshop is hosted by Explore Mars Inc., a non-profit organization dedicated to bringing leading experts from disparate fields together to contribute to creating the first crewed missions to Mars. On May 17th, the results of this year’s workshop were summarized in a report titled “The Tenth Community Workshop for Achievability and Sustainability of Human Exploration of Mars.”

Planetary Protection: Why study it? What can it teach us about finding life beyond Earth?

Universe Today has recently investigated a plethora of scientific disciplines, including impact craters, planetary surfaces, exoplanets, astrobiology, solar physics, comets, planetary atmospheres, planetary geophysics, cosmochemistry, meteorites, radio astronomy, extremophiles, organic chemistry, black holes, and cryovolcanism, while conveying their importance of how each of them continues to teach researchers and the public about our place in the vast universe.

Fall Into a Black Hole With this New NASA Simulation

No human being will ever encounter a black hole. But we can’t stop wondering what it would be like to fall into one of these massive, beguiling, physics-defying singularities.

NASA created a simulation to help us imagine what it would be like.

NASA Confirms that a Piece of its Battery Pack Smashed into a Florida Home

This is the pallet loaded with disused batteries that was jettisoned from the International Space Station with the station's robotic arm. HTV9 is the signature of the Japanese resupply craft that carried new batteries to the ISS. The same pallet used during delivery was used to discard the batteries. Image Credit: NASA

NASA is in the business of launching things into orbit. But what goes up must come down, and if whatever is coming down doesn’t burn up in the atmosphere, it will strike Earth somewhere.

Even Florida isn’t safe.

NASA and Boeing Release New Rendering of their X-66 Sustainable Experimental Airliner

Climate change is arguably the single greatest threat facing the world today. According to the Sixth Assessment Report (AR6) by the UN Intergovernmental Panel on Climate Change (IPCC), average global temperatures are set to increase between 1.5 and 2 °C (2.7 to 3.6 °F) by mid-century. To restrict global temperatures to an increase of 1.5 C and avoid the worst-case scenarios, the nations of the world need to achieve net zero emissions by then. Otherwise, things will get a lot worse before they get better, assuming they ever do.

This means transitioning to cleaner methods in terms of energy, transportation, and aviation. To meet our climate commitments, the aviation industry is developing technology to significantly reduce air travel’s carbon footprint. To help meet this goal, NASA and Boeing have come together to create the X-66 Sustainable Experimental Airliner, the first experimental plane specifically focused on helping the U.S. achieve net-zero aviation. Last week, NASA released a new rendering of the concept, giving the public an updated look at the future of air travel.
