Starship Super Heavy breezes through wind tunnel testing at NASA Ames
A 1.2% scale model of the Super Heavy rocket that will launch the Starship human landing system to the Moon for future crewed Artemis missions was recently tested at NASA’s Ames Research Center’s transonic wind tunnel, providing valuable information on vehicle stability when re-entering Earth’s atmosphere.

NASA and its industry partners continue to make progress toward Artemis III and beyond, the first crewed lunar landing missions under the agency's Artemis campaign.

SpaceX, the commercial Human Landing System (HLS) provider for Artemis III and Artemis IV, recently tested a 1.2% scale model of the Super Heavy rocket, or booster, in the transonic Unitary Plan Wind Tunnel at NASA's Ames Research Center in California's Silicon Valley.

In 2025, NASA will launch its first mission to image the magnetic fingerprint of intense electrical currents that flow high in our atmosphere when auroras shimmer above Earth's poles.

The EZIE (Electrojet Zeeman Imaging Explorer) mission is designed to make groundbreaking measurements of the auroral electrojets, electrical currents about 60 miles (100 kilometers) above the ground in a layer of Earth's atmosphere called the ionosphere, which separates Earth from surrounding space.

The mission features a trio of CubeSats, or small satellites, with an orbit that goes pole to pole to map the electrojets. Mapping the electrojets can give scientists greater insight into the physics of Earth's magnetosphere and help create better models for predicting the effects of space weather phenomena such as and auroras in the and at Earth's surface.

Cosmic radiation is an obstacle to space travel...stop it with BNNT fibers!
Applications of BNNT-based functional fabrics / The BNNT-based composite fibers can be manufactured into fabrics of various shapes and sizes through weaving. The developed fabrics can be utilized in clothing to protect astronauts, crew members, soldiers, firefighters, health care workers, and power plant workers who are expected to be exposed to radiation.

Polaris Dawn project aims to prevent bone loss in space

Dartmouth researchers have a project aboard the Polaris Dawn mission they hope will help address two major health risks of space flight—the breakdown of astronauts' bones in zero-gravity conditions and the resulting danger of developing kidney stones.

When subjected to weightlessness, bones freed from the burden of supporting the human body leach calcium. The shedding of this critical element reduces bone density and, as the calcium enters the urine, heightens the chance of painful forming in the .

Through Polaris Dawn, which launched from Florida on Sept. 10, researchers at Dartmouth's Geisel School of Medicine and Thayer School of Engineering are testing a critical element of a handheld device the team is developing that would alert crew members to high levels of calcium in their urine during so they can take action.

As part of the Artemis lunar exploration campaign, NASA aims to deepen its understanding of the moon's surface and prepare for future Mars missions. The Artemis missions will target the lunar south pole, a region that holds scientific interest due to its permanently shadowed areas, which may contain water ice reserves vital for sustaining human exploration. This will be NASA's first crewed moon

European Space Agency (ESA) engineers are advancing the capabilities of autonomous Mars rovers, as demonstrated in recent trials conducted in a UK quarry. The ExoMars Rosalind Franklin rover, nicknamed "Codi," showcased its ability to locate and retrieve sample tubes using its robotic arm and sophisticated computer vision system. Codi drove to the sample locations with a remarkable accurac

Many imagine the solar system's edge is marked by Neptune, the furthest known planet. However, astrophysicist Susanne Pfalzner from Forschungszentrum Julich notes, "Several thousand celestial bodies are known to move beyond the orbit of Neptune." It is estimated that tens of thousands of objects larger than 100 kilometers exist in this region. "Surprisingly, many of these so-called trans-Neptuni

Using a Google AI tool, scientists have revealed how proteins in a heat-loving microbe respond to intense pressure, similar to conditions found in the planet's deepest ocean trenches. This research offers key insights into how life's building blocks may have evolved under early Earth conditions and opens new doors for future studies. The research, now published in 'PRX Life', highlights th

In a new study, astronomers report novel evidence regarding the limits of planet formation, finding that after a certain point, planets larger than Earth have difficulty forming near low-metallicity stars. Using the sun as a baseline, astronomers can measure when a star formed by determining its metallicity, or the level of heavy elements present within it. Metal-rich stars or nebulas form

The mystery of how supermassive black holes, which can be millions of times more massive than the sun and sit at the heart of most galaxies, came to exist is one of the great questions in astrophysics. Researchers from the Nevada Center for Astrophysics at UNLV (NCfA) have uncovered new evidence that the supermassive black hole at the center of the Milky Way, called Sagittarius A' (Sgr A')
