Heating and cooling space habitats isn’t easy – one engineering team is developing a lighter, more efficient solution

China, India and the U.S. have all achieved landing on the Moon in the 2020s. Once there, their eventual goal is to set up a base. But a successful base – along with the spacecraft that will carry people to it – must be habitable for humans. And a big part of creating a habitable base is making sure the heating and cooling systems work. That’s especially true because the ambient temperature of potential places for a base can vary widely. Lunar equatorial temperatures can range from minus 208 to 250 degrees Farenheit (minus 130 to 120…

Nuclear ‘pasta’ cooked up by dead stars could unravel the secrets of stellar afterlife

Imagine cooking pasta at a temperature of over a trillion degrees. But this isn’t just any ordinary Sunday-night dish; it’s the “nuclear pasta” found inside neutron stars. Researchers have just revealed that these strange nuclear shapes penetrate far deeper into the cores of neutron stars than we ever thought possible, and that this can radically alter the properties of those dead stars. Neutron stars are the very definition of extreme. The leftover cores of some of the most massive stars in the universe, they usually cram a few suns’ worth…

After NASA’s epic OSIRIS-REx capsule landing success, spacecraft heads to asteroid Apophis on new mission

The NASA probe that delivered precious samples of the space rock Bennu to Earth is now on an extended voyage to study an infamous near Earth asteroid. OSIRIS-REx completed NASA’s first asteroid sample return mission on Sunday (Sept. 24), when its reentry capsule landed in the western Utah desert. But now the main spacecraft has embarked on a side quest: to scope out and get up close with Apophis, an asteroid previously thought to potentially pose a threat to Earth. The spacecraft used its return to Earth to fling itself…

SpaceX to launch 21 Starlink satellites from California early on Sept. 25

A SpaceX Falcon 9 rocket will launch from California early Monday morning (Sept. 25), carrying 21 Starlink satellites to orbit. The Falcon 9 is scheduled to lift off from Vandenberg Space Force Base in Florida Monday at 3:23 a.m. EDT (0723 GMT; 12:23 a.m. local California time).  You can watch it live via SpaceX‘s account on X (formerly Twitter); coverage will start about five minutes before liftoff.

NASA’s OSIRIS-REx spacecraft releases asteroid sample capsule toward Earth in flyby, heads to Apophis

The first asteroid samples ever collected by NASA are closing in on Earth for a historic landing in the Utah desert today (Sept. 24).  NASA’s OSIRIS-REx spacecraft, which collected samples of asteroid Bennu in 2020, released a capsule carrying that precious cargo at 6:42 a.m. EDT (1042 GMT) on a course to land on Earth. The spacecraft was 63,000 miles (101,388 kilometers) from Earth, about one-third the distance to the moon, when it released the sample capsule, with OSIRIS-REx itself flying past our planet to a new destination, NASA officials…

Spending time in space can harm the human body — but scientists are working to mitigate these risks before sending people to Mars

When 17 people were in orbit around the Earth all at the same time on May 30, 2023, it set a record. With NASA and other federal space agencies planning more manned missions and commercial companies bringing people to space, opportunities for human space travel are rapidly expanding. However, traveling to space poses risks to the human body. Since NASA wants to send a manned mission to Mars in the 2030s, scientists need to find solutions for these hazards sooner rather than later. As a kinesiologist who works with astronauts, I’ve spent years studying the…
