NASA data points to Mars underground water source at Arcadia Planitia site
Mars’s Arcadia Planitia may be hiding buried treasure. A new global map indicates that the region could be harboring a supply of water, mere inches below its surface.
Armed with fresh data from NASA’s Mars Reconnaissance Orbiter and the Mars Odyssey spacecraft, researchers identified a promising landing spot for future astronauts. The region is located in the planet’s Northern Hemisphere, and has an ample stash of water ice making it an ideal location for any potential human mission to Mars.
A new paper published in Geophysical Research Letters on Dec. 10 details a treasure maps of sorts, pointing to places where researchers believe water ice lurks as little as an inch (2.5 centimeters) below the surface.
Researchers are trying to narrow down the best places for astronauts to land and this discovery puts Arcadia Planitia near the top of the list. Data also shows that because this is a temperate region, basked in plenty of sunlight, it wouldn’t be difficult to uncover the watery bounty.
“You wouldn’t need a backhoe to dig up this ice. You could use a shovel,” lead author Sylvain Piqueux, who studies planetary surfaces at NASA’s Jet Propulsion Laboratory in California, said in a statement.
The Mars we see today is a barren, desert world, devoid of water deposits on its surface. That’s because any liquid water that might trickle on its surface evaporates very quickly. Mars’s once ample atmosphere, eroded over time, stripped away by solar particles, resulting in the thin atmosphere we see today.
As a result, any liquid water on the surface would evaporate immediately when exposed to the thin atmosphere.
That doesn’t mean that Mars is completely devoid of any water on its surface. There’s plenty of water trapped in ice caps at the Martian poles. However, this is a viable solution for human missions as the polar regions are too cold and dark to be viable options for landing. And NASA hopes that future human missions will be able to rely on what they call “in-situ resource utilization”, meaning relying on the resources in a given area.
The new map was created by combining data from two long-running Martian spacecraft: NASA’s Mars Reconnaissance Orbiter and Mars Odyssey. Each orbiter used onboard heat-sensitive instruments to detect the ice since buried ice changes the temperature of the surface. To corroborate their findings, the scientists cross-referenced their work with other data — like ice seen in radar instruments and Mars Odyssey’s gamma-ray spectrometer, a tool designed to spotting water ice deposits.
Water is a precious commodity and thanks to this new data, NASA is hoping that future missions can land near Arcadia Planitia and use its resources instead of having to travel to the poles and hauling water back.
The agency hopes that this map will also identify other promising areas. See it’s not just water that the map is locating, it’s also other valuable resources. When broken down into its components (hydrogen and oxygen), astronauts could not only get water to drink, but could also make rocket fuel, thus decreasing the load they would need to haul from Earth.

Elon Musk called it Epic: The full story of SpaceX’s Starship Flight 12
Starship V3 reached space, survived reentry, and proved it can fly with engines out.
After two scrubbed attempts, SpaceX launched Starship V3 on Friday, May 22 from the brand new Pad 2 at Starbase, Texas, completing the most technically complex test flight the program has attempted and moving the bar in ways that matter for everything from commercial satellites to the first human Moon landing since 1972.
The Super Heavy booster lost an engine early during ascent and several more failed during its boostback burn, sending the stage into an off-nominal descent that ended in a hard landing in the Gulf of Mexico. SpaceX had planned a soft splashdown rather than a tower catch on this first V3 flight, so losing the booster was expected to be acceptable within the test parameters.
Ship 39 told a different story. The Starship upper stage reached its planned sub-orbital trajectory despite losing one of its vacuum Raptor engines, with the remaining engines compensating for the loss and keeping the vehicle on course. The spacecraft then survived atmospheric reentry, completed its belly-flip maneuver, and made a controlled upright splashdown in the Indian Ocean west of Australia.

The payload test is where Flight 12 separated itself from every previous Starship mission. SpaceX deployed 22 objects including 20 Starlink simulator satellites sized like next-generation V3 Starlink units, plus two specially modified satellites equipped with cameras that scanned Starship’s heat shield from orbit and transmitted imagery back to operators.
The broader significance of what was tested on Friday goes well beyond one mission. Every future Starship deployment, whether it is a batch of operational Starlink V3 satellites, cargo bound for the Moon, or eventually crew headed to Mars, depends on SpaceX being able to inspect and certify the heat shield quickly between flights. The camera-equipped satellites deployed on Flight 12 are the first step toward making that inspection process automated and data-driven rather than manual and time-consuming. If SpaceX can scan the heat shield from orbit after every reentry and flag damaged or missing tiles before the vehicle even lands, it fundamentally changes the turnaround time between flights. For a program that needs to refuel Starship in orbit using ten or more tanker launches before a single Moon mission can depart, launch cadence is everything. Friday’s payload test can be seen as building the maintenance infrastructure for rapid reusability.
Elon Musk took to X, following the successful tests, and noting: “Congratulations @SpaceX team on an epic first Starship V3 launch and landing!” “You scored a goal for humanity.”
The stakes behind that goal are concrete. NASA has selected Starship as the Human Landing System for Artemis IV, targeting a crewed Moon landing in 2028, and SpaceX has yet to demonstrate a full orbital flight, in-orbit refueling, or docking with an Orion capsule. Flight 12 proved V3 can fly, survive reentry, and deploy payloads under engine-out conditions. That is the foundation everything else has to be built on, and with a SpaceX IPO targeting June 2026, the timing of that proof of concept could not have been more useful.
SpaceX has decided to stand down from what was supposed to be the first test launch of Starship’s v3 rocket tonight after a minor issue with a hydraulic pin delayed the flight once more.
The company scrubbed its first test flight of the upgraded Starship v3 on May 21 in the final minutes of the countdown. SpaceX CEO Elon Musk quickly took to social media platform X, explaining that a hydraulic pin on the launch tower’s “chopsticks” arm failed to retract properly.
Musk added that the company would fix the issue this evening. SpaceX will attempt another launch tomorrow night at 5:30 p.m. CT, 6:30 p.m. ET, and 3:30 p.m. PT.
The hydraulic pin holding the tower arm in place did not retract.
If that can be fixed tonight, there will be another launch attempt tomorrow at 5:30 CT. https://t.co/DJAdvDYQpH

The countdown for Starship Flight 12 — featuring the taller and more capable V3 stack with Booster 19 and Ship 39 — had been progressing smoothly until the late-stage issue surfaced. The Mechazilla tower arm, designed to secure the vehicle on the pad and eventually catch returning boosters, could not complete its retraction sequence.
SpaceX teams immediately began troubleshooting the hydraulic system for an overnight repair.
Starship V3 introduces several significant upgrades over earlier versions. These include greater propellant capacity, more powerful Raptor 3 engines, larger grid fins, enhanced heat shielding, and an improved fuel transfer system.
We covered the changes that were announced just days ago by SpaceX:
SpaceX unveils sweeping Starship V3 upgrades ahead of May 19 launch
The changes are intended to increase payload performance, support higher flight rates, and advance the vehicle toward operational missions, including Starlink deployments, NASA Artemis lunar landings, and future crewed Mars flights. The debut flight from Starbase’s new Launch Pad 2 marked an important milestone in scaling up the fully reusable Starship system.
This stand-down highlights the intricate challenges of preparing the world’s most powerful rocket for flight. Despite extensive pre-launch checks, a single component in the ground support equipment can force a scrub.
The incident aligns with Starship’s proven iterative development approach. Previous test flights have encountered both successes and setbacks, each providing critical data that refines hardware and procedures. Some outlets may call some of these flights “failures,” when in reality, they are all opportunities for SpaceX to learn for the next attempt.
With V3, SpaceX aims to reduce ground-system dependencies and increase launch cadence to meet ambitious long-term goals.
SpaceX has revealed the date for the maiden voyage of Starship v3, its newest and most advanced version of the rocket yet.
Starship v3 represents a significant leap forward. At 124 meters tall when fully stacked, it stands taller than previous versions and boasts substantial upgrades.
The vehicle incorporates next-generation Raptor 3 engines, which deliver higher thrust, improved reliability, and simplified designs with fewer parts. Both the Super Heavy booster (Booster 19) and the Starship upper stage (Ship 39) feature these enhancements, along with structural improvements for greater payload capacity—exceeding 100 metric tons to low Earth orbit in reusable configuration.
SpaceX and its CEO Elon Musk have announced that the company aims to push the first launch of Starship v3 this Thursday. Musk included some clips of past Starship launches with the announcement.

There are a lot of improvements to Starship v3 from past builds. Key hardware changes include a more robust heat shield, upgraded avionics, and modifications optimized for orbital refueling, a critical technology for future missions to the Moon and Mars. This flight marks the first launch from Starbase’s second orbital pad, allowing parallel operations and accelerating the cadence of tests.
This will be the 12th Starship launch for SpaceX. Flight 12 objectives include a full ascent profile, hot-staging separation, in-space engine relights, and reentry testing. The booster is expected to perform a controlled splashdown in the Gulf of Mexico, while the ship will deploy 20 Starlink simulator satellites and a pair of modified Starlink V3 units before attempting reentry.
Success would validate V3’s design for operational use, paving the way for rapid reusability and higher flight rates.
The rapid evolution from V2 to V3 underscores SpaceX’s iterative approach. Previous flights demonstrated booster catches, ship landings, and heat shield advancements. V3 builds on these with nearly every component refined, supported by an expanding production line at Starbase that churns out vehicles at an unprecedented pace.
Starship V3 is here putting SpaceX closer to Mars than it has ever been
This launch comes amid growing momentum for SpaceX’s ambitious goals. Starship is central to NASA’s Artemis program for lunar landings and Elon Musk’s vision of making humanity multiplanetary. A successful V3 debut would boost confidence in achieving orbital refueling and crewed missions in the coming years.
As excitement builds, enthusiasts and engineers alike await liftoff. Weather and technical readiness will determine the exact timing, but the community is optimistic. Starship V3 is poised to push the boundaries of spaceflight once again, bringing reusable interplanetary transport closer to reality.
