LOGAN, Utah — Spaceflight shipped its Sherpa-LTC2 orbital transfer vehicle (OTV) Aug. 10 to Cape Canaveral in Florida, where it will make a second attempt to debut the chemically powered space tug on a SpaceX launch.
The Space Force will take over control of the Wideband Global Satcom and Defense Satellite Communications System constellations of military satellites. The satellites were built and launched by the U.S. Air Force but the Army controlled the payloads.
In a new study, researchers studied two types of underwater snow found on Earth as an analog for understanding how Europa’s shell thickens from below. Frazil ice forms in supercooled water columns and floats upward to accrete onto the bottom of ice shelves, while congelation ice grows directly from under the ice shelf. Intriguingly, the researchers determined that ice formed by these processes retains just a fraction of the salt from the water from which it formed. Frazil ice retains just 0.1% of the ocean’s salinity and could be common on Europa, according to the study, suggesting that Europa’s ice shell could be orders of magnitude purer than previous estimates.
New evidence supports the idea that Earth’s continents were created in its distant past when massive meteorites struck the planet.
The Air Force said Starlink is ‘the only LEO satellite network provider that is currently being used in a contested environment: Ukraine’
WASHINGTON — The U.S. Air Force Special Operations Command awarded SpaceX a $1.9 million one-year contract to evaluate Starlink internet services in Europe and Africa starting this month.
SAN FRANCISCO – Telespazio intends to play a key role in the future in-orbit servicing market, providing customers seeking satellite relocation, refueling, repair or removal with the necessary space and ground-based capabilities.
SAN FRANCISCO – Orbion Space Technology will supply a propulsion system for a U.S. Space Force prototype weather satellite, under a contract with General Atomics Electromagnetic Systems (GA-EMS).
WASHINGTON — The British government announced a series of measures June 23, from regulations to funding active debris removal projects, intended to make the country a leader in space sustainability.
WASHINGTON — The two companies NASA selected earlier this month to develop spacesuits for the International Space Station and Artemis lunar missions were the only companies to bid on the project, according to agency procurement documents.
Solar cycle 25 kicked off last year. Forecasters thought it would be a mild one, but it’s turning out to be quite the opposite. From its onset, this solar cycle has been steadily outpacing predictions, producing more sunspots and spewing way more solar wind, flares and eruptions than the world’s leading experts predicted.
A new simulation of NASA’s Double Asteroid Redirection Test (DART) mission suggests that rather than leaving a crater behind, the DART impactor could severely deform the small asteroid it will collide with.
Among the first pictures coming in from the $10 billion James Webb Space Telescope will be “the deepest image of our universe that has ever been taken,” according to NASA administrator Bill Nelson.
You can help NASA scientists do cloudspotting on Mars for free using the Zooniverse platform. Sign up for the project here at Zooniverse (opens in new tab). The project, dubbed Cloudspotting on Mars, will invite people to look through 16 years of photos collected by NASA’s Mars Reconnaissance Orbiter (MRO), which has operated at the Red Planet since 2006.
TALLINN, Estonia — Chinese launch service provider Expace has secured $237 million in B round funding, following last week’s return to flight of its Kuaizhou-1A solid rocket.
