Scientists from the European Space Agency have found a way to make oxygen out of moon dust in hopes to one day help astronauts use resources on the moon to make breathable air and even rocket fuel.

The Moon has a massive supply of oxygen — a valuable resource needed for future human missions. However, that supply is not in the atmosphere, but instead, contained within the dust on the lunar surface.

Stationed at the Materials and Electrical Components Laboratory of the European Space Research and Technology Centre (ESTEC), which is based in the Netherlands, scientists are looking for ways to facilitate living off-planet.

Last year, a group of European scientists proposed an idea on how to extract oxides from lunar regolith — a term used to describe the mixture of loose dust and dirt that covers solid rock. Now, they’ve taken that research one step further and built a prototype extractor to show how the technology would work.

If it works, it has huge implications for the future of deep space travel. Having a capability like this would provide people access to crucial resources that could facilitate the establishment of long-term bases on the moon and Mars.

“Having our own facility allows us to focus on oxygen production, measuring it with a mass spectrometer as it is extracted from the regolith simulant,” Beth Lomax, a chemist from the University of Glasgow in Scotland said in a news statement.

Thanks to samples brought back from the Moon’s surface, we know that the lunar regolith is teeming with oxygen (roughly 40–45% percent by weight). Unfortunately, that supply is not easily accessible.

Previous attempts to extract the oxygen from the regolith haven’t been that successful. But Lomax and her team, think they have what it takes. And it requires a bit of chemistry.

Using a technique called molten salt electrolysis, the regolith is first placed in a metal basket with molten Calcium chloride (an electrolyte) is added to it. The mixture is then heated to around 950 degrees Celsius. (It may sound hot but it’s still below the melting point of the regolith.)

Next, an electrical current is applied. This extracts the oxygen, so it can be easily removed.

The method was first developed by a UK company called Metalysis for commercial metal production. Lomax worked at the company while earning her PhD and recreated the process at ESTEC.

Her team says this method can extract up to 96 percent of the oxygen from the regolith; as an added bonus, the left over material is a mix of metal alloys.

The remnants can then be used for other projects, perhaps even as building materials fed into a 3D printer.

With ESA and NASA both planning on returning to the moon in the coming years, the team’s ultimate goal is to build a version that could operate on the moon.  That could happen sometime in the mid-2020s.

“We are working towards a sustained human presence on the Moon, and maybe one day, Mars,” explained Tommaso Ghidini, Head of the Structures, Mechanisms and Materials Division at the ESA.

This research could help make that goal possible.

SpaceX is opening up its internet service, Starlink, to those impacted by Hurricane Melissa, as it made landfall in Jamaica and the Bahamas as a Category 5 storm.

Hurricane Melissa is expected to reach wind speeds of over 165 MPH over the next few days as it extends out into the Atlantic Ocean by Thursday and Friday.

Citizens in Jamaica and the Bahamas have been preparing for the storm for the past week, getting necessary goods together and preparing for the massive storm to arrive. It finally did yesterday, and the first images and video of the storm are showing that it could destroy many parts of both countries.

Starlink is now being opened up for free until the end of November for those impacted by the storm in Jamaica and the Bahamas, SpaceX announced today:

It is a move similar to the one the company made last year as Hurricane Helene made its way through the United States, destroying homes and property across the East Coast. SpaceX offered free service for those impacted by the destruction caused by the storm.

The free Starlink service was available until the end of 2024.

Elon Musk’s companies have also made similar moves to help out those who are impacted by natural disasters. Tesla has offered Free Supercharging in the past, most notably during the California wildfires.

One major advantage of Starlink is that it is available for use in situations like this one, where power might be required to operate things like a modem and router.

Internet access is a crucial part of survival in these situations, especially as it can be the last leg some stand on to get in touch with emergency services or loved ones.

SpaceX has reached an incredible milestone with its Starlink program, officially surpassing 10,000 satellites launched into low Earth orbit since starting the program back in 2019.

Last Sunday, October 19, SpaceX launched its 131st and 132nd Falcon 9 missions of 2025, one from Cape Canaveral, Florida, and the other from Vandenberg, California.

The 10,000th Starlink satellite was aboard the launch from California, which was Starlink 11-19, and held 28 v2 mini optimized satellites.

The achievement was marked by a satellite tracker developed by Jonathan McDowell.

The first Starlink launch was all the way back on May 23, 2019, as SpaceX launched its first 60 satellites from Cape Canaveral using a Falcon 9 rocket.

Of the over 10,000 satellites in orbit, the tracker says 8,608 are operational, as some are intentionally de-orbited after becoming faulty and destroyed in the atmosphere.

SpaceX has truly done some really incredible things during its development of the Starlink program, including launch coverage in a global setting, bringing along millions of active subscribers that use the service for personal and business use, locking up commercial partnerships, and more.

Starlink currently operates in around 150 countries, territories, and markets and is available at least somewhere on all seven continents.

Additionally, Starlink has over 5 million subscribers worldwide, and 2.7 million have joined the program over the past year. It has revolutionized internet access on commercial aircraft as well, as several high-profile airlines like Qatar and United, among many others, have already installed Starlink on some of their planes to deliver more stable connectivity for passengers and crew.

SpaceX has the approval to launch 12,000 Starlink satellites from the FAA, but it plans to bring over 30,000 to its constellation, giving anyone the ability to have access to high-speed internet.

SpaceX aces its eleventh Starship test launch on Monday evening, marking the company’s second consecutive takeoff that crossed off each of the planned mission objectives.

It was also the final launch of the V2 Starship rocket. The twelfth test flight will feature the larger V3 Starship rocket, followed by V4, which will eventually make the first trip to Mars.

The launch was overwhelmingly successful. In its 12th test flight, SpaceX was able to achieve every major mission objective, including the second successful deployment of Starlink satellite simulators and the relight of a Raptor engine while in space. The latter achievement demonstrated “a critical capability for future deorbit burns,” the company said.

The ship officially launched at 6:23 p.m. local time in Starbase, Texas, with all 33 engines igniting and sending the Ship to space.

Stage separation occurred just over eight minutes later, and Super Heavy started its descent back to the Gulf of America, where it successfully splashed down. The first part of the launch was complete.

Starlink simulators were deployed about twenty-one minutes after launch, as the Pez dispenser sent the faux-satellites out to space without any issue:

Perhaps the most anticipated part of the launch was with Starship’s banking maneuver and subsequent splashdown in the Indian Ocean.

Prior to Starship 11’s launch and successful re-entry and splashdown, SpaceX had lost a few vehicles during this portion of the previous flights.

However, the company had made tremendous improvements and has now aced two consecutive launches. On Monday, its approach and splashdown were both overwhelmingly successful:

The re-entry phase of this particular Starship launch aimed to gather data on the performance of the heatshield, SpaceX said. The heatshield was intentionally stressed to its limits to determine how much it could withstand without failing.

SpaceX will now turn its focus to the next vehicles, including V3, which is larger, more capable, and will help the company gather even more information about its launches into space:

CEO Elon Musk has said the third-generation Starship rocket will be built and tested by the end of the year.
