NASA's ECOSTRESS detects 'heat islands' in extreme Indian heat wave
Monday, 23 May 2022 09:13A relentless heat wave has blanketed India and Pakistan since mid-March, causing dozens of deaths, fires, increased air pollution, and reduced crop yields. Weather forecasts show no prospect of relief any time soon. NASA's Ecosystem Spaceborne Thermal Radiometer Experiment on Space Station instrument (ECOSTRESS) has been measuring these temperatures from space, at the highest spatial resolution
Self-cleaning spacecraft surfaces to combat microbes
Monday, 23 May 2022 06:09Astronauts live and work in orbit along with teaming populations of microorganisms, which could present a serious threat to health – and even the structural integrity of spacecraft. To help combat such invisible stowaways, an ESA-led project is developing microbe-killing coatings suitable for use within spacecraft cabins.

Military looking for new ways to acquire and use commercial satellite data
Monday, 23 May 2022 04:01Space Systems Command is trying to figure out how to exploit traditional and new types of commercial space data
The post Military looking for new ways to acquire and use commercial satellite data appeared first on SpaceNews.
Starliner launches to remain on Atlas 5
Sunday, 22 May 2022 22:21WASHINGTON — Boeing and United Launch Alliance say they remain committed to launching future CST-100 Starliner commercial crew missions on Atlas 5 rockets even after that vehicle is effectively retired for other missions.
Artemis I Moon Rocket to Return to Launch Pad 39B in Early June
Sunday, 22 May 2022 10:02The Space Launch System (SLS) rocket and Orion spacecraft are slated to return to launch pad 39B at NASA's Kennedy Space Center in Florida in early June for the next wet dress rehearsal attempt. Engineers successfully completed work on a number of items observed during the previous wet dress rehearsal test. This includes addressing the liquid hydrogen system leak at the tail service mast u
Sampling Strategy for the Delta Front Campaign
Sunday, 22 May 2022 10:02The past few weeks have been exciting ones for Perseverance's science team. At the "Enchanted Lake" site, we took our first look at what appear to be some of the bottommost sedimentary layers that make up the Jezero crater delta. Since then, we've re-traced our steps back towards "Three Forks" and have begun the ascent of the delta near "Hawksbill Gap." It's along this Hawksbill Gap route
China's Zhurong rover switches to dormant mode in severe Martian dust storm
Sunday, 22 May 2022 10:02Mars rover Zhurong has been switched to dormant mode while waiting out a dust storm on the surface of the planet, the China National Space Administration said on Friday. The latest images taken by cameras onboard China's Tianwen-1 Mars orbiter show a dust storm passing over the patrol area of Zhurong. Scientists compared them with photos taken in the last two months and analyzed recent pow
Airbus to further develop LISA gravitational wave observatory mission
Sunday, 22 May 2022 10:02Airbus has been awarded a contract from the European Space Agency (ESA) to further develop the implementation of LISA (Laser Interferometer Space Antenna), one of the most ambitious science missions ESA has planned to date. With Phase B1 now underway, the detailed mission design and final technology development activities for the gravitational wave observatory are due to be completed by 2024, wi
Hubble Reaches New Milestone in Mystery of Universe's Expansion Rate
Sunday, 22 May 2022 10:02Completing a nearly 30-year marathon, NASA's Hubble Space Telescope has calibrated more than 40 "milepost markers" of space and time to help scientists precisely measure the expansion rate of the universe - a quest with a plot twist. Pursuit of the universe's expansion rate began in the 1920s with measurements by astronomers Edwin P. Hubble and Georges Lemaitre. In 1998, this led to the di
Unraveling a perplexing explosive process that occurs throughout the universe
Sunday, 22 May 2022 10:02Mysterious fast radio bursts release as much energy in one second as the Sun pours out in a year and are among the most puzzling phenomena in the universe. Now researchers at Princeton University, the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) and the SLAC National Accelerator Laboratory have simulated and proposed a cost-effective experiment to produce and obse
New calculations of Solar spectrum resolve decade-long controversy about the Sun's chemical composition
Sunday, 22 May 2022 10:02Astronomers have resolved the decade-long solar abundance crisis: the conflict between the internal structure of the Sun as determined from solar oscillations (helioseismology) and the structure derived from the fundamental theory of stellar evolution, which in turn relies on measurements of the present-day Sun's chemical composition. New calculations of the physics of the Sun's atmosphere yield
Ghostly 'mirror world' might be cause of cosmic controversy
Sunday, 22 May 2022 10:02New research suggests an unseen 'mirror world' of particles that interacts with our world only via gravity that might be the key to solving a major puzzle in cosmology today - the Hubble constant problem. The Hubble constant is the rate of expansion of the universe today. Predictions for this rate - from cosmology's standard model - are significantly slower than the rate found by our most
NASA's HyTEC to Help Jets Burn Less Fuel
Sunday, 22 May 2022 10:02Cleveland OH (SPX) May 20, 2022 What if we told you we could reimagine the way a jet engine works to generate the same amount of power using less fuel? Our aeronautical innovators are designing a new jet engine that, compared to current engines, will produce the same thrust and even look the same on the outside, but is more fuel-efficient. HyTEC, or Hybrid Thermally Efficient Core,
The missing piece to faster, cheaper and more accurate 3D mapping
Sunday, 22 May 2022 10:02Three-dimensional (3D) mapping is a very useful tool, such as for monitoring construction sites, tracking the effects of climate change on ecosystems and verifying the safety of roads and bridges. However, the technology currently used to automate the mapping process is limited, making it a long and costly endeavor. "Switzerland is currently mapping its entire landscape using airborne lase
