The first television broadcast satellite under SES's C-band lifted off from Cape Canaveral on Wednesday evening on a SpaceX rocket. SES, a video and data solutions company, said the satellite will free up the lower 300 MHz of C-band spectrum to ensure the company can provide video and data services to its customers while enabling wireless operators to quickly deploy 5G services across t

Just like us, robots can't see through walls. Sometimes they need a little help to get where they're going. Engineers at Rice University have developed a method that allows humans to help robots "see" their environments and carry out tasks. The strategy called Bayesian Learning IN the Dark - BLIND, for short - is a novel solution to the long-standing problem of motion planning for robots that wo

Cloaked in darkness and mystery, the creatures of the deep oceans exist in a world of unlikely profusion, surviving on scant food and under pressure that would crush human lungs. This extremely hostile environment, which will come under the spotlight at a major United Nations oceans summit in Lisbon this week, has caused its inhabitants to develop a prodigious array of alien characteristics

Astronauts lose decades' worth of bone mass in space that many do not recover even after a year back on Earth, researchers said Thursday, warning that it could be a "big concern" for future missions to Mars. Previous research has shown astronauts lose between one to two percent of bone density for every month spent in space, as the lack of gravity takes the pressure off their legs when it co

Reemphasizing a critical joint partnership in all-domain warfare, Air Force Chief of Staff Gen. CQ Brown, Jr. met with his fellow service chiefs from the Army, Navy, Marine Corps and Space Force June 24 to share advancements and discuss the way forward as the services work together to continue cultivating common ground on Joint All-Domain Command and Control. The meeting focused on the Def

"I'll miss the "ah ha" moments," said Col. Eric Felt, director of the Air Force Research Laboratory Space Vehicles Directorate, who will depart AFRL for an assignment at the Pentagon in July. Felt became the Space Vehicles director in July 2018 and has a dual-hatted role as commander of AFRL's Phillips Research Site, both located at Kirtland AFB. He will be taking on the job of the directo

A NASA aircraft will fly over the I-95 corridor from Washington to Baltimore and Hampton, Virginia, in support of an atmospheric campaign in the mid-Atlantic region between July 5 and 16, 2022. The four-engine turboprop P-3 aircraft, based at NASA's Wallops Flight Facility in Virginia, will fly five days during the 12-day period at altitudes from 1,000 to 10,000 feet. Each flight dur

Researchers have shown that a new mid-infrared spectrometer can precisely measure the ratios of different forms of water - known as isotopologues - in atmospheric water vapor through open air in a little over 15 minutes. Isotopologue ratios, which can be affected by land-based water evaporation and plant transpiration, are used to develop models of climate change and to understand how water is t

“After Euclid’s lifetime, it will just be floating in space. What if future beings found Euclid? How would they know anything about the humanity of the people?” – Tom Kitching, lead scientist of Euclid’s VIS instrument.

The team behind ESA’s Euclid mission has come together to create something special – a personal and collective galaxy-shaped fingerprint painting that has been attached to the spacecraft ready to launch into space. The collaborative nature of the artwork reflects the collaborative nature of the Euclid project overall; in both cases, people have come together to build something unique.

The Fingertip Galaxy was

The second of NASA's James Webb Space Telescope's four primary scientific instruments, known as the Mid-Infrared instrument (MIRI), has concluded its postlaunch preparations and is now ready for science.

The last MIRI mode to be checked off was its coronagraphic imaging capability, which uses two different styles of masks to intentionally block from hitting its sensors when attempting to make observations of the star's orbiting planets. These customized masks allow for scientists to directly detect and study around their host stars in a way that's never been done before.

Along with Webb's three other instruments, MIRI initially cooled off in the shade of Webb's tennis-court-size sunshield to about 90 Kelvin (minus 298 degrees Fahrenheit, or minus 183 degrees Celsius). To perform its intended science meant dropping to less than 7 Kelvin—just a few degrees above the lowest temperature matter can reach—by using an electrically powered cryocooler. These extreme operating temperatures allow for MIRI to deliver mid-infrared images and spectra with an unprecedented combination of sharpness and sensitivity.
