NASA Awards Contract for Infrastructure, Applications, Communications

NASA has awarded the Kennedy Infrastructure, Applications and Communication (KIAC) contract to ASRC Federal Data Solutions, LLC of Beltsville, Maryland.

NASA Television to Air Launch of Next Communications Satellite

NASA is targeting 8:03 a.m. EDT Friday, Aug. 18, for the launch of its next Tracking and Data Relay Satellite (TDRS) mission atop a United Launch Alliance Atlas V rocket from Cape Canaveral Air Force Station in Florida. The launch, and related activities that begin Thursday, Aug. 17, will air live on NASA Television and the agency’s website.

Now you can levitate liquids and insects at home

Levitation techniques are no longer confined to the laboratory thanks to University of Bristol engineers who have developed an easier way for suspending matter in mid-air by developing a 3D-printed acoustic levitator.

Soft and spherical: Researchers study dynamics of drop impact

Within the study of fluid dynamics, the effect of curved, convex or compliant surfaces on the dynamics of impacting drops is still relatively unknown, despite its extreme relevance to modern-day applications, such as 3-D ink-jet printing and the delivery of pesticides on leaves. Researchers have now detailed these effects by investigating the impact of water droplets on spherical soft surfaces.

Relativistic self-focusing gives mid-IR driven electrons a boost

For the first time, scientists have observed the production of relativistic electrons driven by low-energy, ultrashort mid-infrared laser pulses.

Video: Dark matter hunt with LUX-ZEPLIN

Researchers at the Department of Energy's SLAC National Accelerator Laboratory are on a quest to solve one of physics' biggest mysteries: What exactly is dark matter – the invisible substance that accounts for 85 percent of all the matter in the universe but can't be seen even with our most advanced scientific instruments?

Atomically thin layers bring spintronics closer to applications

Scientists have created a graphene-based device, in which electron spins can be injected and detected with unprecedented efficiency. The result is a hundredfold increase of the spin signal, big enough to be used in real life applications, such as new spin transistors and spin-based logic.

ATLAS observes direct evidence of light-by-light scattering

Physicists from the ATLAS experiment at CERN have found the first direct evidence of high energy light-by-light scattering, a very rare process in which two photons – particles of light – interact and change direction. The result, published today in Nature Physics, confirms one of the oldest predictions of quantum electrodynamics (QED).

Total Eclipse: Solar Research Thrives in Darkness

Scientists study our turbulent star and its dynamic relationship with Earth.

NASA Signs Combined Data Services Agreement for Polar Satellite Program

NASA has procured combined data support services under an agreement with the Norwegian Space Centre in Oslo, Norway, for the Joint Polar Satellite System (JPSS) program and various cooperative international missions. This action is supported under an international agreement between the United States and Norway.
