NASA is leading an effort, working with the Department of Energy (DOE), to advance space nuclear technologies. The government team has selected three reactor design concept proposals for a nuclear thermal propulsion system. The reactor is a critical component of a nuclear thermal engine, which would utilize high-assay low-enriched uranium fuel. The contracts, to be awarded through the DOE'

One of the biggest challenges facing the space sector is orbital congestion and space debris. There are currently around 3,000 working satellites in orbit, and an estimated 130 million other pieces of debris, including old satellites, spent rocket bodies and even tools dropped by astronauts. One collision could create thousands of small, fast-moving fragments, damaging the satellites that

Dr. Iair Arcavi, a Tel Aviv University researcher at the Raymond and Beverly Sackler Faculty of Exact Sciences, participated in a study that discovered a new type of stellar explosion - an electron-capture supernova. While they have been theorized for 40 years, real-world examples have been elusive. Such supernovas arise from the explosions of stars 8-9 times the mass of the sun. The discovery a

An international team of astronomers, including scientists from the Max Planck Institute for Astronomy, have become the first in the world to detect isotopes in the atmosphere of an exoplanet. It concerns different forms of carbon in the gaseous giant planet TYC 8998-760-1 b at a distance of 300 light-years in the constellation Musca (Fly). The weak signal was measured with ESO's Very Larg

A newly discovered visitor to the outer edges of our Solar System has been shown to be the largest known comet ever, thanks to the rapid response telescopes of Las Cumbres Observatory. The object, which is named Comet C/2014 UN271 Bernardinelli-Bernstein after its two discoverers, was first announced on Saturday, June 19th, 2021. C/2014 UN271 was found by reprocessing four years of data fr

NASA has identified the possible cause of the payload computer problem that suspended Hubble Space Telescope science operations on June 13. The telescope itself and science instruments remain healthy and in a safe configuration. The payload computer resides in the Science Instrument Command and Data Handling (SI C&DH) unit. It controls, coordinates, and monitors Hubble's science instrument

As the Parker Solar Probe ventures closer to the sun, we are learning new things about our home star. In a new study, physicists led by the University of Iowa report the first definitive measurements of the sun's electric field, and how the electric field interacts with the solar wind, the fast-flowing current of charged particles that can affect activities on Earth, from satellites to tel

LaserCube, Stellar Project's frst optical communication terminal for small satellites, has been launched into space onboard D-Orbit's ION Satellite Carrier in SpaceX's Falcon 9 Transporter-2 mission. Now, the company is ready to test the payload in orbit. Padua - Stellar Project space technology startup, launches LaserCube Maiden Flight. The payload hosted on D-Orbit's ION Carrier has lift

The European Space Agency (ESA), as part of its Ariane 6 Competitiveness Improvement Program, has chosen ArianeGroup to develop and build a complementary stage (kick-stage) for Ariane 6, called ASTRIS, which will enable Arianespace, operator of the new European launcher, to place with even greater efficiency a larger number of payloads in different orbits, or to inject satellites into geostation

On June 7, 2021, NASA's Juno spacecraft flew closer to Jupiter's ice-encrusted moon Ganymede than any spacecraft in more than two decades. Less than a day later, Juno made its 34th flyby of Jupiter, racing over its roiling atmosphere from pole to pole in less than three hours. Using the spacecraft's JunoCam imager, the mission team has put together this animation to provide a "starship captain"
