Cost and schedule overruns continue to grow for NASA programs
Monday, 24 May 2021 10:27
WASHINGTON — NASA suffered increasing cost overruns on its major programs again in 2020, a problem a new report says will be exacerbated by the pandemic.
The annual report by the Government Accountability Office (GAO) on major NASA programs, published May 20, found that costs of those programs grew by more than $1 billion in 2020, the fifth year in a row overall costs increased.
NASA rocket mission studying escaping radio waves
Monday, 24 May 2021 10:17
A NASA rocket mission, launching May 26, 2021, will study radio waves that escape through the Earth's ionosphere impacting the environment surrounding GPS and geosynchronous satellites, such as those for weather monitoring and communications.
Launching from NASA's Wallops Flight Facility, a Terrier-Improved Malemute suborbital sounding rocket will carry the Vlf trans-Ionospheric Propagation Experiment Rocket, or VIPER. The mission is scheduled for 9:15 p.m., Wednesday, May 26. The launch window is 9:15 p.m. to midnight EDT and the backup days are May 27-28. The launch may be visible in the mid-Atlantic region.
VIPER is studying very low frequency radio, or VLF, waves that are produced by both natural (e.g. lightning) and artificial means. During the day these waves are trapped or absorbed by the Earth's ionosphere. At night, however, some of the waves escape through the ionosphere and accelerate electrons in the Van Allen Radiation Belt.
"At night, the lower layers of the ionosphere are much less dense, and more of the VLF can leak through, propagate along the Earth's magnetic field lines, and end up interacting with the high-energy electrons trapped in the Van Allen Radiation Belts," said Dr.

Air Force unveils exoskeleton to aid aerial ports in lifting
Monday, 24 May 2021 01:38
An exoskeleton, worn by U.S. Air Force aerial porters to assist in lifting objects with reduced strain, will make its debut at Travis Air Force Base, Calif., the branch announced on Wednesday.
The device, designed by Arizona State University and the Air Force Life Cycle Management and Air Mobility Command, will be used in an official capacity for the first time this week.

WASHINGTON — The U.S. Space Force next month will solicit industry bids for deep-space radar sensors that can track active satellites and debris in high orbits above 22,000 miles.
One or more contractors will be selected to develop prototype concepts for the Deep Space Advanced Radar Concept (DARC), a project started by the U.S.
China's first Mars rover starts exploring red planet
Saturday, 22 May 2021 23:07
China's first Mars rover, Zhurong, drove down from its landing platform to the Martian surface Saturday, leaving the country's first "footprints" on the red planet. Zhurong's first successful drive made China the second country after the United States to land and operate a rover on Mars.
