NASA Science, Cargo Launch on 33rd SpaceX Resupply Mission to Station

NASA News - 3 hours 23 min ago

Following a successful launch of NASA’s SpaceX 33rd commercial resupply mission, new scientific experiments and cargo for the agency are bound for the International Space Station.

The SpaceX Dragon spacecraft, carrying more than 5,000 pounds of supplies to the orbiting laboratory, lifted off at 2:45 a.m. EDT on Sunday, on the company’s Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida.

“Commercial resupply missions to the International Space Station deliver science that helps prove technologies for Artemis lunar missions and beyond,” said acting NASA Administrator Sean Duffy. “This flight will test 3D printing metal parts and bioprinting tissue in microgravity – technology that could give astronauts tools and medical support on future Moon and Mars missions.”


Live coverage of the spacecraft’s arrival will begin at 6 a.m., Monday, Aug. 25, on NASA+, Netflix, Amazon Prime, and more. Learn how to watch NASA content through a variety of platforms, including social media.

The spacecraft is scheduled to dock autonomously at approximately 7:30 a.m. to the forward port of the space station’s Harmony module.

In addition to food, supplies, and equipment for the crew, Dragon will deliver several experiments, including bone-forming stem cells for studying bone loss prevention and materials, to 3D print medical implants that could advance treatments for nerve damage on Earth. Dragon also will deliver bioprinted liver tissue to study blood vessel development in microgravity, as well as supplies to 3D print metal cubes in space.

These are just a sample of the hundreds of biology and biotechnology, physical sciences, Earth and space science investigations conducted aboard the orbiting laboratory. This research benefits people on Earth while laying the groundwork for other agency deep space missions. As part of NASA’s Artemis campaign, the agency will send astronauts to the Moon to prepare for future human exploration of Mars, inspiring the world through discovery in a new Golden Age of innovation and exploration.

During the mission, Dragon also will perform a reboost demonstration of station to maintain its current altitude. The hardware, located in the trunk of Dragon, contains an independent propellant system separate from the spacecraft to fuel two Draco engines using existing hardware and propellant system design. The boost kit will help sustain the orbiting lab’s altitude starting in September with a series of burns planned periodically throughout the fall of 2025. During NASA’s SpaceX 31st commercial resupply services mission on Nov. 8, 2024, the Dragon spacecraft performed its first demonstration of these capabilities.

The Dragon spacecraft is scheduled to remain at the space station until December, when it will depart the orbiting laboratory and return to Earth with research and cargo, splashing down off the coast of California.

Advancing Lunar Habitats with Thermoelectric Power Generation

Universe Today - Sat, 08/23/2025 - 11:29pm

How can thermoelectric generators (TEGs) help advance future lunar surface habitats? This is what a recent study published in Acta Astronautica hopes to address as a team of researchers from the Republic of Korea investigated a novel technique for improving power efficiency and reliability under the Moon’s harsh conditions. This study has the potential to help mission planners, engineers, and future astronauts develop technologies necessary for deep space human exploration to the Moon and beyond.

Halley-Like Comets Could Have Seeded Earth With Water

Universe Today - Sat, 08/23/2025 - 11:29pm

Comets are like the archeological sites of the solar system. They formed early on, and their composition helps us understand what the area around the early Sun was like, potentially even before any planets were formed. A new paper from researchers at a variety of US and European institutions used the Atacama Large Millimeter Array (ALMA) to capture detailed spatial spectral images of comet 12P/Pons-Brooks, which is very similar to the famous Halley’s comet, and might hold clues to where the water on the Earth came from.

The JWST has found another moon orbiting Uranus. It's the planet's 29th known moon, and it bears the uninspiring, temporary name S/2025 U1. It's too small and faint to be detected by the Hubble, or by Voyager 2, the only spacecraft to visit the ice giant.

Sensors Could Permanently Fly In The "Ignorosphere" Using Novel Propulsion Technique

Universe Today - Sat, 08/23/2025 - 11:29pm

Earth’s atmosphere is large, extending out to around 10,000 km from the surface of the planet. It’s so large, in fact, that scientists break it into five separate sections, and there’s one particular section that hasn’t got a whole lot of attention due to the difficulty in keeping any craft afloat there. Planes and balloons can visit the troposphere and stratosphere, the two sections closest to the ground, while satellites can sit in orbit in the thermosphere and exosphere, allowing for a platform for consistent observations. But the mesosphere, the section in the middle, is too close to have a stable orbit, but too sparse in air for traditional airplanes or balloons to work. As a result, we don’t have a lot of data on it, but it impacts climate and weather forecasting, so scientists have simply had to make a lot of assumptions about what it's like up there. But a new study from researchers at Harvard and the University of Chicago might have found a way to put stable sensing platforms into the mesosphere, using a novel flight mechanism known as photophoresis.

NASA Commanded Psyche To Turn Around And Capture Images Of Earth And The Moon

Universe Today - Sat, 08/23/2025 - 11:29pm

New images from NASA's Psyche spacecraft show that its cameras are working just fine. By pointing them at Earth and the Moon, NASA was able to test the spacecraft's cameras and science instruments. Since both bodies reflect light like Psyche, and since their spectra are familiar, it's a valuable opportunity to test and calibrate the instruments.

Roman's High-Latitude Time-Domain Survey Will Find Tens of Thousands of Supernovae

Universe Today - Sat, 08/23/2025 - 11:29pm

For thousands of years, humanity viewed the skies as unchanging, except for a few “wandering stars” (that we now know are planets). As we improved our ability to perceive the cosmos with light-gathering telescopes and electronic detectors, we realized that the universe is full of things that change in brightness, whether it be an exploding star or a matter-gulping black hole. NASA’s Nancy Grace Roman Space Telescope is poised to deliver an avalanche of such transients, including thousands of “standard candle” supernovae that allow us to measure the expansion history of the universe.

The hunt will be on shortly, to once again recover a clandestine mission in low Earth orbit. SpaceX is set to launch a Falcon-9 rocket from launch pad LC-39A at the Kennedy Space Center Thursday night August 21st, with the classified USSF-36 mission. The U.S. Space Force has announced that this is the eighth mission for its fleet of two Orbital Test Vehicles (OTV-8). This is the automated ‘mini-space shuttle’ about the size of a large SUV that launches like a rocket, and lands like a plane.

Sometimes inspiration can strike from the most unexpected places. It can result in a cross-pollination between ideas commonly used in one field but applied to a completely different one. That might have been the case with a recent paper on lightsail design from researchers at the University of Nottingham that used techniques typically used in video games to develop a new and improved structure of a lightsail.

Tidal Forces and Orbital Evolution of Habitable Zone Planets

Universe Today - Sat, 08/23/2025 - 11:29pm

How do tidal forces determine a planet’s orbital evolution, specifically planets in the habitable zone? This is what a recently submitted study hopes to address as an international team of researchers investigated how tidal forces far more powerful than experienced on Earth could influence orbital evolution of habitable zone planets with highly eccentric orbits around low-mass stars. This study has the potential to help researchers better understand the formation and evolution of exoplanets, specifically regarding where we could find life beyond Earth.
