UVA Engineering assistant professor Chen Cui is finding the hidden patterns in electric propulsion plasma beams that could help ensure the success of long-term space missions.

University of Washington scientists recently discovered that the giant 'conveyer belt' currents that push star-forged material out of our galaxy and pull it back in can also transport carbon atoms. That means that a good deal of the carbon here on Earth, including the carbon in our bodies, likely left the galaxy at some point!

A NASA X-ray imager is heading to the Moon as part of NASA's Artemis campaign, where it will capture the first global images of the magnetic field that shields Earth from solar radiation.

The Lunar Environment Heliospheric X-ray Imager, or LEXI, instrument is one of 10 payloads aboard the next lunar delivery through NASA’s CLPS (Commercial Lunar Payload Services) initiative, set to launch from the agency's Kennedy Space Center in Florida no earlier than mid-January, with Firefly Aerospace’s Blue Ghost Lander. The instrument will support NASA’s goal to understand how our home planet responds to space weather, the conditions in space driven by the Sun.

In the solar system, Icy Worlds such as Europa and Enceladus hold great potential for extraterrestrial life and may provide humanity an answer, within this century, to the age-old question of life beyond Earth. Exo-AUV technology shows promise in life detection in the icy shell, at the ice-water interface and on the seafloor of Exo-ocean. Space agencies, including NASA and DLR, are enthusiastic about deploying Exo-AUVs to explore life in these regions. However, the where and how to find life, the technologies to be utilized and the goals to be achieved are crucial aspects for future Exo-AUV life detection missions on Icy Worlds. This study delves into a hypothetical mission of life detection on Europa, discussing science goals, detectable objects, potential regions and biogenic analysis for Icy Worlds. It proposes a life detection strategy for Icy Worlds based on Exo-AUVs, presents key contextual elements for Exo-AUV operations, outlines technological requirements for hull, payloads and autonomy, introduces the current state of Exo-AUV research and addresses existing challenges. This study also suggests a roadmap for conceptual development of Exo-AUV and a Concept of Operations for Multiple Exo-AUV System (ConOps for MEAS). This system aims to assist planetary scientists and astrobiologists in exploring Icy Worlds, identifying robust biosignatures and potentially discovering extant organisms, even prebiotic chemical systems.
