A collaboration led by scientists at Nagoya University in Japan has investigated the nature of dark matter surrounding galaxies seen as they were 12 billion years ago, billions of years further back in time than ever before. Their findings, published in Physical Review Letters, offer the tantalizing possibility that the fundamental rules of cosmology may differ when examining the early history o Super-earth skimming habitable zone of red dwarf

A super-Earth planet has been found near the habitable zone of a red dwarf star only 37 light-years from the Earth. This is the first discovery by a new instrument on the Subaru Telescope and offers a chance to investigate the possibility of life on planets around nearby stars. With such a successful first result, we can expect that the Subaru Telescope will discover more, potentially even bette Northrop Grumman to lead Homeland Missile Defense Program for MDA

Northrop Grumman Corporation (NYSE: NOC) has been awarded an indefinite delivery, indefinite quantity contract with a maximum amount of $3,286,745,005 by the Missile Defense Agency (MDA) for the Ground-based Midcourse Defense (GMD) Weapon System (GWS) program.

For a long time, our view of Ceres was fuzzy, said Scott King, a geoscientist in the Virginia Tech College of Science. A dwarf planet and the largest body found in the asteroid belt - the region between Jupiter and Mars speckled with hundreds of thousands of asteroids - Ceres had no distinguishable surface features in existing telescopic observations from Earth.

For this 3-sol weekend plan, I worked as the Tactical Uplink Lead. This morning we came in to discover that the drive had stopped early due to high slip on the steep terrain, and our parking place was not a safe spot to unstow and use the arm. So we quickly switched gears and loaded up the plan with lots of remote science.

Every year, the Airbus Foundation delivers satellite imagery covering tens of thousands of square kilometres around the globe to support its partners involved in humanitarian aid and protecting the environment. As the number of requests continues to grow, the Foundation has significantly extended the range of products and services offered - including new types of imagery, photo interpretation an Utah's Great Salt Lake is disappearing

Utah's Great Salt Lake dropped to its lowest recorded water level last month as a megadrought persists across the US southwest, forcing the fast-growing city to curb its water use. From space, satellite images show how water levels have fallen from 1985 to 2022 - exposing large expanses of lakebed.
According to data from the US Geological Survey, the Great Salt Lake's surface water elevati NASA revises requirements for ISS private astronaut missions

100% bio-sourced thermoset composites tested for space
Tuesday, 02 August 2022 04:19 Write a comment
Combining high strength with low weight, corrosion-resistant and shapeable into almost any form, composite materials are a key ingredient of modern life: employed everywhere from aviation to civil engineering, sports equipment to dentistry – and also a vital element of space missions. But they have some less desirable aspects: produced from petroleum products, they are non-renewable in nature and also non-recyclable. So ESA is working with Côte D’Azur University on a new breed of space-quality composites made from wholly sustainable sources.

Proposal by research team could revolutionize space medicine, improve astronaut health

Often when researching the molecular and biological changes that happen in space, models such as rodents, worms, and yeast are used to study the effects and consequences of long-duration space flight as a way to understand how microgravity impacts humans in space. However, OHIO's Nate Szewczyk, Ph.D., and several other researchers from around the world have published a paper that proposes a program for the European Space Agency that could potentially revolutionize space medicine by routinely collecting biological samples from astronauts for use with cutting-edge technologies to understand the effects on their genes, mRNA, proteins, and metabolites (commonly referred to as "omics" technologies).
The paper, titled "Routine omics collection is a golden opportunity for European human research in space and analog environments," published in the journal Patterns, details how omics profiling is primed to transform space medicine and improve occupational healthcare for astronauts. The paper's authors anticipate that omics profiling will improve astronauts' health and mitigate spaceflight risks, which could increase mission success on more ambitious endeavors such as voyages to Mars. The group of researchers go on to highlight in the paper the collaborative steps that should be taken to design a standardized data resource that can be used for years to come as data and science evolves.
