Topic: NASA’s Gleen Research Center
Responding to an emergency like this – or a hurricane or search and rescue effort, to name a few – requires extensive collaboration among a host of groups that, right now, is coordinated manually under challenging conditions. This makes communication difficult. ![]() Illustration of an Unmanned Aircraft System, or drone, in front of a smoke-filled sky. A goal of the Scalable Traffic Management for Emergency Response Operations project, or STEReO, is to make emergency response efforts more targeted and adaptable, for instance by integrating drones into wildfire fighting.

NASA teams with University Hospitals to combat COVID-19
A team of researchers recently developed and tested two new approaches that could enable health care professionals to sanitize face masks on-site and safely reuse them. These approaches also may be useful to the aerospace community when traditional sterilization techniques might not be available. ![]() NASA teams with University Hospitals to create new ways to decontaminating personal protective equipment (PPE).

NASA uses SHIIVER tank to test keeping liquid fuel cool
But as the extreme environment of space warms a spacecraft, the fuels begin to evaporate or “boiloff.” “As energy from the Sun, Earth, and even the Moon enters the cryogenic propellant tanks, the liquid has to absorb that energy, which causes it to boiloff,” explains Wesley Johnson, cryogenic fluid management technical lead at NASA’s Glenn Research Center in Cleveland. ![]() SHIIVER is 13-foot diameter test tank built by NASA to evaluate technologies aimed at reducing the evaporation or “boiloff” losses in large cryogenic storage tanks for human exploration missions.

NASA selects U.S. Companies, Partnerships to help develop Moon, Mars Tech
NASA has selected 13 U.S. companies for 19 partnerships to mature industry-developed space technologies and help maintain American leadership in space. NASA centers will partner with the companies, which range from small businesses with fewer than a dozen employees to large aerospace organizations, to provide expertise, facilities, hardware and software at no cost. ![]() Illustration of a human landing system and crew on the lunar surface with Earth near the horizon.

NASA tests new high power electric systems for CubeSatsNASA Glenn Research Center
Completely designed and led by a team of 12 early career scientists and engineers at NASA’s Glenn Research Center in Cleveland, the Advanced Electrical Bus, or ALBus, will be the first CubeSat to demonstrate power management and distribution of a 100-watt electrical system. The CubeSat will also employ a custom-built SMA release mechanism and hinges to deploy solar arrays and conduct electricity. ![]() The ALBus CubeSat sits at NASA Glenn with its four solar array deployed. The solar arrays on this high-power CubeSat use a custom-designed shape memory alloy construction allowing for greater design flexibility.

NASA successfully tests lightweight, Aircraft Wings that fold during FlightWritten by Matt Kamlet
The recent flight series, which took place at NASA’s Armstrong Flight Research Center in California, was part of the Spanwise Adaptive Wing project, or SAW. This project aims to validate the use of a cutting-edge, lightweight material to be able to fold the outer portions of aircraft wings and their control surfaces to optimal angles in flight. SAW, which is a joint effort between Armstrong, NASA’s Glenn Research Center in Cleveland, or GRC, Langley Research Center in Virginia, Boeing Research & Technology in St. Louis and Seattle, and Area-I Inc. in Kennesaw, Georgia, may produce multiple in-flight benefits to aircraft in the future, both subsonic and supersonic. ![]() The subscale testbed PTERA flies over NASA Armstrong Flight Research Center in California with the outer portions of its wings folded 70 degrees upwards. The aircraft took off with its wings zero degrees deflection, keeping them level during takeoff. The wings were folded during the flight using a thermally-triggered shape memory alloy, developed at Glenn Research Center and integrated into an actuator at Boeing Research & Technology.

A Look Back at NASA’s efforts to send Astronauts into Deep Space from 2017NASA Headquarters
Construction Completed for Stand to Test SLS’s Largest Fuel Tank Major construction is complete on NASA’s structural test stand that will ensure SLS’s liquid hydrogen tank can withstand the extreme forces of launch and ascent. Together, the SLS liquid hydrogen and liquid oxygen tanks will feed 733,000 gallons (nearly 3 million liters) of super-cooled propellant to four RS-25 engines, producing a total of 2 million pounds of thrust at the base of the core stage. ![]() The 215-foot-tall structural test stand for NASA’s Space Launch System is seen Sunday, Sept. 24, 2017, at NASA’s Marshall Space Flight Center in Huntsville, Alabama.

NASA on QueSST for Low Noise Supersonic FlightWritten by Jimi Russell
Think about it. Commercial flight over land in a supersonic jet would mean less time in-flight; less time in a cramped seat next to your new, and probably unwanted, best friend; fewer tiny bags of peanuts; and more time at your destination. Couldn’t Concorde do that? Nope. Concorde, which last flew in 2003, utilized 1950s technology, was only supersonic over the ocean and was deemed too noisy to fly over people. ![]() A NASA Glenn technician prepares the QueSST experimental aircraft for testing in the 8’ x 6’ wind tunnel.
