The Mars Perseverance Rover will fly 300 million miles over almost seven months, but the seven minutes spent waiting to receive a radio signal confirming the rover has landed will seem like an eternity for scientists and researchers back on Earth.
That wait is dubbed the "seven minutes of terror" and Briony Horgan, Purdue University associate professor of planetary science, calls it the sc Extreme black holes have hair that can be combed

Black holes are considered amongst the most mysterious objects in the universe. Part of their intrigue arises from the fact that they are actually amongst the simplest solutions to Einstein's field equations of general relativity.
In fact, black holes can be fully characterized by only three physical quantities: their mass, spin and charge. Since they have no additional "hairy" attributes Metamaterial tiles boost sensitivity of large telescopes

A multi-institutional group of researchers has developed new metamaterial tiles that will help improve the sensitivity of telescopes being built at the preeminent Simons Observatory in Chile. The tiles have been incorporated into receivers that will be deployed at the observatory by 2022.
The Simons Observatory is the center of an ambitious effort to measure the cosmic microwave background UN and UK sign agreement to promote space sustainability

The agreement will help nations ensure that outer space remains safe and sustainable for future generations.
The increasing complexity of space missions, the emergence of large constellations of satellites and the increased risks of collision all affect the long-term sustainability of space activities. And there are currently approximately 170 million objects in orbit - mainly debris - whi Motiv Space Systems and JPL to develop robotic arm for extreme cold environments

Fire affects an estimated four million square kilometres of Earth’s land each year and is responsible for releasing aerosols and greenhouse gases to the atmosphere. Understanding the influence that this has on atmospheric chemistry and representing these emissions in future climate predictions is, however, complex and remains poorly understood. To improve the situation, a team of scientists working as part of ESA’s Climate Change Initiative is using satellite observations, such as from Copernicus Sentinel-3, to gain a global view of land burned by fire.
