The NIRSpec instrument is the workhorse near-infrared spectrograph on board the James Webb Space Telescope and is provided by ESA.
NIRSpec will allow scientists to study objects embedded in shrouds of gas and dust, to find out more about how galaxies formed and evolved, and to characterise the atmospheres of exoplanet to determine if water is present.
The primary goal of NIRSpec is to enable large spectroscopic surveys of astronomical objects like stars or distant galaxies. This is made possible by its powerful multi-object spectroscopy mode, which will make use of use of roughly a quarter of a
Tiny probes could sail to outer planets with the help of low-power lasers
Wednesday, 23 February 2022 13:32 Write a comment
Space travel can be agonizingly slow: For example, the New Horizons probe took almost 10 years to reach Pluto. Traveling to Proxima Centauri b, the closest habitable planet to Earth, would require thousands of years with even the biggest rockets. Now, researchers calculate in ACS' Nano Letters that low-power lasers on Earth could launch and maneuver small probes equipped with silicon or boron nitride sails, propelling them to much faster speeds than rocket engines.

The satellite industry is set for unprecedented transformation, with the impact of cloud-based systems, the introduction of next-generation NGSO broadband constellations, and convergence towards a unified 5G network architecture. However, ground segments will also have to play a pivotal role to allow the industry to fully embrace and benefit from these changes.
While satellites have embark Monitoring Arctic permafrost with satellites, supercomputers, and deep learning
Wednesday, 23 February 2022 04:57 Write a comment
Permafrost - ground that has been permanently frozen for two or more years - makes up a large part of the Earth, around 15% of the Northern Hemisphere. Permafrost is important for our climate, containing large amounts of biomass stored as methane and carbon dioxide, making tundra soil a carbon sink. However, permafrost's innate characteristics and changing nature are not broadly understood.
