New tests evaluate mission readiness of astronauts upon landing
Thursday, 14 April 2022 03:54
Have you ever felt off-balance after being on amusement rides or gotten motion sickness on a boat? Astronauts feel something similar that can be more intense when they return to Earth from space.
Once they land, their whole body - including muscles, bones, inner ear, and organs - starts readjusting to Earth's gravity. Astronauts often report feeling dizzy, lightheaded, nauseated, and off-b Digging into drill data takes perseverance

Drilling is on hold while the rover focuses on driving, so the sampling team is off studying the data we have acquired so far. What kind of information do we get from the drill, and how do the rocks we have drilled so far compare to each other?
One of the first things we look at is how difficult it was for the drill to make progress through the rock. The rover has a rotary percussive drill Breaking news from the dawn of the universe

An international effort led by astrophysicists at the Niels Bohr Institute, University of Copenhagen, and the Technical University of Denmark, have identified a distant object with properties that lie in-between those of a galaxy and those of a so-called quasar. The object can be seen as the ancestor of a supermassive black hole, and it was born relatively soon after the Big Bang. Simulations ha Hubble sheds light on origins of supermassive black holes

Astronomers have identified a rapidly growing black hole in the early universe that is considered a crucial "missing link" between young star-forming galaxies and the first supermassive black holes. They used data from NASA's Hubble Space Telescope to make this discovery.

With help from a cryocooler, Webb's Mid-Infrared Instrument has dropped down to just a few degrees above the lowest temperature matter can reach and is ready for calibration.
The James Webb Space Telescope will see the first galaxies to form after the Big Bang, but to do that its instruments first need to get cold - really cold. On 7 April, Webb's Mid-Infrared Instrument (MIRI) - a joint d DLR research observatory to be named after Johannes Kepler

Johannes Kepler Observatory - this will be the name of the new research observatory of the German Aerospace Center (Deutsches Zentrum fur Luft- und Raumfahrt; DLR). Work is currently underway to put the facility into operation at the Empfingen Innovation Campus. The observatory is a core research facility for the DLR Institute of Technical Physics. In future, it will be used to determine the tra How to compete with robots

When it comes to the future of intelligent robots, the first question people ask is often: how many jobs will they make disappear? Whatever the answer, the second question is likely to be: how can I make sure that my job is not among them?
In a study just published in Science Robotics, a team of roboticists from EPFL and economists from the University of Lausanne offers answers to both que NASA's Fermi hunts for gravitational waves from monster black holes
Thursday, 14 April 2022 03:54
Our universe is a chaotic sea of ripples in space-time called gravitational waves. Astronomers think waves from orbiting pairs of supermassive black holes in distant galaxies are light-years long and have been trying to observe them for decades, and now they're one step closer thanks to NASA's Fermi Gamma-ray Space Telescope.

James Webb telescope's coldest instrument reaches operating temperature
Wednesday, 13 April 2022 19:53
NASA's James Webb Space Telescope will see the first galaxies to form after the Big Bang, but to do that, its instruments first need to get cold—really cold. On April 7, Webb's Mid-Infrared Instrument (MIRI)—a joint development by NASA and ESA (European Space Agency)—reached its final operating temperature below 7 kelvins (minus 447 degrees Fahrenheit, or minus 266 degrees Celsius).
