In-situ resource utilization (ISRU) is commonly cited as being a critical step towards a sustainable human presence in space, especially on the Moon. Just how crucial it is, and how much its by-products will affect other uses of the Moon, is still up for debate. A new paper from Evangelia Gkaravela and Hao Chen of the Stevens Institute of Technology dives into those questions and comes up with a promising answer - ISRU is absolutely worth it, if we can control the waste products.

We step inside the TARDIS to rank every Doctor so far, from William Hartnell through to Ncuti Gatwa.

Oil industry opposition to a planned OSHA rule to limit heat deaths comes as oil and gas workers face increasingly dangerous conditions

NASA astronaut Nichole Ayers and Japan Aerospace Exploration Agency astronaut Takuya Onishi spoke with students from the International Space Station on May 20, 2025, in a behind-the-camera view.

British climbers recently reached the top of Mount Everest in record time. They inhaled xenon gas before the trip. But was that the decisive factor?

NASA's Perseverance rover has marked a milestone with a spectacular new selfie, and a surprise visitor.

Just because we can find ozone in the atmosphere of other planets doesn't mean there's life. Ozone is a sign of life on Earth, but its detection on Venus shows that it can also be produced abiotically. This indicates that there are different pathways for its creation, not only on Venus but also on other Venus-like exoplanets.

China's Tianwen 2 spacecraft launched on Tuesday (May 28), kicking off a bold mission to grab a sample of one of Earth's "quasi-moons" and then journey on to a mysterious comet.

What happens when you see something that just doesn’t make sense? Perhaps you rub your eyes and consider it an anomaly. But what if you see it in an experiment? Say, travelling electrons that make different patterns depending upon whether they were detected? Then, you might want to change your sense of reality. Now, if you can develop a theory for the observations, then maybe you can start a new field of science. It has happened. Quantum mechanics is the name given to this relatively new field and it’s the topic that Sean Carroll writes in his book, “The Biggest Ideas in the Universe – Quanta and Fields”. In his book, there’s much ado about particles, fields, groups and diagrams; all with the aim of enabling any reader to make sense of it.

Blue Origin's next suborbital flight is scheduled to launch on Saturday (May 31), carrying a diverse crew of educators, entrepreneurs and adventurers.

The Canon RF 35mm f/1.4L VCM is a longer wide-angle lens offering a versatile focal length for photography and video alongside a fast maximum aperture.

Since 1966 NASA’s Goddard Institute for Space Studies has been at the forefront of Earth and planetary science from its location in upper Manhattan. Now a Trump administration directive is ejecting its scientists to parts unknown

Using a newly developed adaptive optics system called Cona, scientists peered through Earth's turbulent air to reveal the sun's corona in astonishing clarity.

A celestial object some 15,000 light-years away is emitting bright flashes of radio and X-rays that scientists are struggling to explain

The failure of SpaceX’s ninth Starship launch has raised fresh concerns about the future of the rocket, but is there any alternative to Elon Musk’s approach to space?

Quantum computers that correct their own errors usually require hundreds of thousands of qubits. Start-up Nord Quantique claims it can dramatically decrease that number – but many challenges remain
