China's conducted 100s of hypersonic weapon tests
Monday, 01 November 2021 07:48Gen. Hyten's remarks come a week after a failed US hypersonic test and as tensions between the US and China over Taiwan, which the latter considers as an integral part of its territory, remain high, as well as recent reports of China allegedly conducting a successful test of a new potentially nuclear hypersonic missile in August. Following China's purported test of a hypersonic missile, th
Carbon nanotubes could help electronics withstand outer space's harsh conditions
Monday, 01 November 2021 07:48Space missions, such as NASA's Orion that will take astronauts to Mars, are pushing the limits of human exploration. But during their transit, spacecrafts encounter a continuous stream of damaging cosmic radiation, which can harm or even destroy onboard electronics. To extend future missions, researchers reporting in ACS Nano show that transistors and circuits with carbon nanotubes can be config
Satellite images show positive impact of conservation efforts for China's coastal wetlands
Monday, 01 November 2021 07:48Coastal wetlands support diverse and vital ecosystems central to coastal areas' biodiversity and economic vitality. However, coastal wetlands are threatened by sea level rise that can lead to flooding and land use changes that alter the way people can live or work in these areas. These impacts are large. Approximately 600 million people live less than 10 meters, approximately 6 miles, above sea
VR technology enables users to see individual cells in human body
Monday, 01 November 2021 07:48Researchers at Harvard Medical School in Boston have developed a free, open-access virtual reality program that allows anyone to interact with individual cells in the human body, they said Thursday. The tool, called singlecellVR, enables users to visualize single-cell assays in virtual reality, or VR, with no advanced technical skills required, the researchers said in an article publish
Smart material switches between heating and cooling in minutes
Monday, 01 November 2021 07:48As anyone who has ever parked a car in the sun on a hot summer day knows, glass windows are great at letting sunlight in but terrible at allowing heat out. Now, engineers at Duke University have developed smart window-like technology that, with the flip of a switch, can alternate between harvesting heat from sunlight and allowing an object to cool. The approach could be a boon for HVAC savings,
Astronomers discover massive galaxy 'shipyard' in the distant universe
Monday, 01 November 2021 07:48Even galaxies don't like to be alone. While astronomers have known for a while that galaxies tend to congregate in groups and clusters, the process of going from formation to friend groups has remained an open question in cosmology. In a paper published in the Astronomy and Astrophysics Journal, an international team of astronomers reports the discovery of a group of objects that appear to
Chinese hypersonic test like a "Sputnik moment': top US general
Monday, 01 November 2021 07:48The Pentagon's top general said Wednesday that China's recent test of an earth-circling hypersonic missile was akin to the Soviet Union's stunning launch of the world's first satellite, Sputnik, in 1957, which sparked the superpowers' space race. Mark Milley, chairman of the Joint Chiefs of Staff, confirmed for the first time the Chinese test of a nuclear-capable missile that would be very d
OpenET: A satellite-based water data resource
Monday, 01 November 2021 07:48OpenET uses publicly available data to provide satellite-based information on evapotranspiration (the "ET" in OpenET). The primary satellite dataset for OpenET is from the Landsat program, a partnership between NASA and the U.S. Geological Survey (USGS). The most recent satellite in the program, Landsat 9, successfully launched on Sept. 27, 2021. Evapotranspiration is the process through w
Satellites used to track methane leaks in climate fight
Monday, 01 November 2021 07:48A yellow streak representing high concentrations of methane, a dangerous greenhouse gas, is visible over southern Iraq on a map produced by Kayrros, a French firm that uses satellites to track leaks from fossil fuel facilities. The source of the immense leak discovered in 2019 was never officially confirmed - and it is only one of many. The satellite map shows blotches of colour splatte
ESA accelerates space-based climate action at COP26
Monday, 01 November 2021 07:00ESA is poised to showcase how satellite data underpins global efforts to avert climate catastrophe at pivotal international talks held in the UK.
New Chinese launch firm signs deal for reusable rocket engines
Sunday, 31 October 2021 20:05Rocket Pi of China has signed a deal with a liquid rocket engine maker for supply of engines to power its Darwin-1 reusable launch vehicle.
Falcon Heavy could launch three U.S. Space Force missions in 2022
Sunday, 31 October 2021 15:46USSF-67 is the third U.S. national security launch to be added to the Falcon Heavy’s crowded 2022 manifest.
Beresheet 2 to include two landers and an orbiter

Antarctic glacier named Glasgow to mark COP26
Sunday, 31 October 2021 12:30Nine fast-flowing glaciers in West Antarctica have been named after locations of important climate treaties, conferences and reports. One of the glaciers is now called Glasgow Glacier to mark the city hosting the COP26 climate change conference. All the glaciers are in the Getz region, which, using data from satellites, was found recently to have lost more than 300 gigatonnes of ice over the last 25 years.
