ESA is embarking on the in-orbit demonstration of a new satellite navigation constellation operating much closer to our planet, utilising novel frequencies and capabilities, so the Agency is looking for European companies interested in taking part. Attend ESA’s LEO-PNT Industry Day on 7 March at ESA’s ESTEC technical centre in the Netherlands to find out more.

Emily Timko has the power to control the temperature, form wispy clouds, create ice crystals, and produce powerful gusts of wind. She has a lot in common with Queen Elsa from the movie "Frozen," but she's actually much cooler. Timko is an icing cloud calibration engineer at NASA's Glenn Research Center in Cleveland and works with a team of 14 other engineers and technicians to characterize

CACI International Inc (NYSE: CACI) signed a five-year cooperative research and development agreement (CRADA) with the U.S. Army Space and Missile Defense Technical Center (USASMDC-TC) to further the development of advanced payload technologies, space sensor applications, and resilient Positioning, Navigation and Timing (PNT). Previously, CACI announced a 2023 satellite launch to test a mu

A cloudy day can ruin a trip to the beach, a scenic picnic, and lots of other outdoor activities. But clouds in satellite imagery are also a big issue for remote sensing and land change scientists. When scientists want to study how land surface is changing, they often use composite images consisting of multiple satellite images of the same place to create a representative "snapshot"

Scientists and government agencies have been worried about the space junk surrounding Earth for decades. But humanity's starry ambitions are farther reaching than the space just around Earth. Ever since the 1960s with the launch of the Apollo program and the emergence of the space race between the U.S. and Soviet Union, people have been leaving trash around the Moon, too. Today, experts es

After a 27-hour delay due to poor weather at the launch site and unfavorable booster recovery, SpaceX launched a Falcon 9 rocket on Monday, February 6th, 2023, from Cape Canaveral on a mission to place the new Amazonas Nexus High-throughput Satellite (HTS) into its geostationary transfer orbit (GTO) and towards its geosynchronous equatorial orbit (GEO) position at 61+ West longitude. The

NASA's Atmospheric Waves Experiment (AWE) has successfully completed its critical space environment tests. Planned for launch to the International Space Station, AWE will study gravity waves in Earth's atmosphere to gain a deeper knowledge of the connections caused by climate systems throughout our atmosphere and between the atmosphere and space. From its unique vantage point on the Intern

Engineers at NASA's Goddard Space Flight Center in Greenbelt, Maryland, have finished testing the high-gain antenna for the Nancy Grace Roman Space Telescope. When it launches by May 2027, this NASA observatory will help unravel the secrets of dark energy and dark matter, search for and image exoplanets, and explore many topics in infrared astrophysics. Pictured above in a test chamber, th

An international team of researchers has uncovered what might be a critical step in the chemical evolution of molecules in cosmic "stellar nurseries." In these vast clouds of cold gas and dust in space, trillions of molecules swirl together over millions of years. The collapse of these interstellar clouds eventually gives rise to young stars and planets. Like human bodies, stellar nurserie

European astronomers using the James Webb Space Telescope have detected a previously unknown asteroid about the size of Rome's Colosseum in the main asteroid belt between Mars and Jupiter. The asteroid measuring between 300 and 650 feet (100 to 200 meters) in length is the smallest object observed to date using the telescope, the US space agency NASA said Monday. The European astronomers
