Hidden patterns in electric propulsion plasma beams could help ensure the success of long-term space missions. Go faster, farther, more efficiently.

That’s the goal driving spacecraft propulsion engineers like Chen Cui, a new assistant professor at the University of Virginia School of Engineering and Applied Science. Cui is exploring ways to improve electric propulsion thrusters — a key technology for future space missions.

“In order to ensure the technology remains viable for long-term missions, we need to optimize EP integration with spacecraft systems,” Cui said.

Working with his former adviser, University of Southern California professor Joseph Wang, Cui published findings last month in Plasma Sources Science and Tec...

A new study in published in Physical Review Letters analyzes the most complete set of galaxy clustering data to test the ΛCDM model, revealing discrepancies in the formation of cosmic structures in the universe, hinting at a new physics.

The ΛCDM model is the standard model of cosmology describing the universe’s evolution, expansion, and structure. It encompasses cold dark matter (CDM), normal matter and radiation, and the cosmological constant (Λ), which accounts for dark energy.

The model has been successful in explaining several cosmological observations, including the large-scale structure of the univer...

Fast radio bursts are brief and brilliant explosions of radio waves emitted by extremely compact objects such as neutron stars and possibly black holes. These fleeting fireworks last for just a thousandth of a second and can carry an enormous amount of energy—enough to briefly outshine entire galaxies.

Since the first fast radio burst (FRB) was discovered in 2007, astronomers have detected thousands of FRBs, whose locations range from within our own galaxy to as far as 8 b...

NASA’s upcoming Artemis II mission is slated to return astronauts to the moon no sooner than April 2026. Astronauts were last on the moon in 1972 during the Apollo 17 mission.

Artemis II will utilize NASA’s Space Launch System, which is an extremely powerful rocket that will enable human space exploration beyond Earth’s atmosphere. The crew of four will travel in an Orion spacecraft, which the agency launched around the moon and successfully returned during the Artemis I mission.

But before Artemis II, NASA will send two missions to scout the surface of the lunar south pole for resources that could sustain human space travel and e...
