Space debris: feel the burn
Write a comment
It might be counter-intuitive, but designing satellites to better fall apart is one of the key strategies to combat space debris. Developed by ESA’s Clean Space initiative, the approach is called ‘Design for Demise’ and involves making sure that derelict satellites will break up and burn up fully as they reenter the atmosphere.
Nanostructured device stops light in its tracks

Understanding how light waves oscillate in time as they interact with materials is essential to understanding light-driven energy transfer in materials, such as solar cells or plants. Due to the fantastically high speeds at which light waves oscillate, however, scientists have yet to develop a compact device with enough time resolution to directly capture them.
Now, a team led by MIT resea Scientists at NREL report new synapse-like phototransistor

Researchers at the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) developed a breakthrough in energy-efficient phototransistors. Such devices could eventually help computers process visual information more like the human brain and be used as sensors in things like self-driving vehicles.

The Skyborg leadership team conducted a two-hours and ten minute flight test April 29 of the Skyborg autonomy core system (ACS) aboard a Kratos UTAP-22 tactical unmanned vehicle at Tyndall AFB, Florida.
Termed Milestone 1 of the Autonomous Attritable Aircraft Experimentation (AAAx) campaign, the ACS performed a series of foundational behaviors necessary to characterize safe system operatio Perseverance rover captures sound of Ingenuity flying on Mars

NASA's Perseverance rover has for the first time captured the low-pitched whirring of the Ingenuity helicopter's blades as it flies through the rarefied Martian atmosphere.
The space agency on Friday released new footage shot by the six-wheeled robot of its rotorcraft companion making its fourth flight on April 30 - this time accompanied by an audio track.

A B-52 bomber conducted a successful test of the simulated hypersonic kill chain, using a hypersonic weapon to neutralize a target, the U.S. Air Force said.
The test was a "successful simulated hypersonic kill chain employment from sensor to shooter and back," during the Northern Edge 21 exercises in Alaska, an Air Force statement said on Thursday.

How much water sloshes around in Earth's lakes, rivers, and oceans? And how does that figure change over time? The upcoming Surface Water and Ocean Topography (SWOT) mission plans to find out. Targeting a late-2022 launch date, this SUV-size satellite will measure the height of Earth's water.

The 2020 National Defense Authorization Act (NDAA) called on the US Department of Defense to provide the US Congress with recommendations for a potential Space Force Reserve element. Presently, members of the National Guard are conducting space missions in seven US states and the territory of Guam.

Two space companies that are protesting NASA's $2.9 billion lunar contract award to SpaceX allege the deal would make future moon landings more risky, while the claims leave the timetable for a crewed mission in limbo.
The companies that are protesting the award, Jeff Bezos' Blue Origin and space tech firm Dynetics, have filed formal complaints with the Government Accountability Office, SpaceX to launch lunar mission paid with cryptocurrency Dogecoin

SpaceX will launch a satellite to the Moon next year funded entirely with the cryptocurrency Dogecoin, Canadian company Geometric Energy Corporation, which will lead the lunar mission, announced Sunday.
The satellite, dubbed DOGE-1, will be launched aboard a SpaceX Falcon 9 rocket in the first quarter of 2022, the Calgary-based company said in a statement.
The cubic satellite, weighing 88 pounds (40 kilograms), will aim to obtain "lunar-spatial intelligence from sensors and cameras on-board," according to the statement.
The "DOGE-1 Mission to the Moon" will be "the first-ever commercial lunar payload in history paid entirely with" Dogecoin, Geometric Energy Corporation said, without specifying how much the project cost.
"We're excited to launch DOGE-1 to the Moon!" Tom Ochinero, SpaceX vice president of commercial sales, said in the statement.
"This mission will demonstrate the application of cryptocurrency beyond Earth orbit and set the foundation for interplanetary commerce."
The announcement comes the day after SpaceX founder Elon Musk hosted the live sketch comedy show "Saturday Night Live" (SNL), during which he praised Dogecoin, originally created as a joke but legitimized through the eccentric tech entrepreneur's tweets.
