Starlink satellite drops out of orbit, fears of crashing into the UK

Posted by in categories: internet, space, surveillance

The UK Space Agency tweeted: “We are monitoring its re-entry together with @DefenceHQ, and there is no expectation the re-entry will cause any damage. Due to the varying input data, natural forces and associated observation error, there are always high levels of uncertainty when performing re-entry predictions on any satellite”.

“Today, a Starlink-1855 satellite re-entered the Earth’s atmosphere. There is a chance it will re-enter over the UK, and you might be able to spot the satellite as it burns up. Starlink has a fantastic track record or orchestrating safe and reliable re-entries. We do not expect the return of the satellite to cause any damage. Still the UK Space Agency and the Ministry of Defence continually monitor and assess the re-entries of satellite and debris and any risk to British territories through our joined Space Surveillance and Tracking capabilities”.

Largest virtual universe free for anyone to explore

Posted by in categories: alien life, computing, particle physics

Forget about online games that promise you a “whole world” to explore. An international team of researchers has generated an entire virtual universe, and made it freely available on the cloud to everyone.

Uchuu (meaning “outer space” in Japanese) is the largest and most realistic simulation of the to date. The Uchuu simulation consists of 2.1 trillion particles in a computational cube an unprecedented 9.63 billion light-years to a side. For comparison, that’s about three-quarters the distance between Earth and the most distant observed . Uchuu reveals the evolution of the universe on a level of both size and detail inconceivable until now.

SpaceX wins contract to launch weather satellite after ULA withdraws

Posted by in category: satellites

WASHINGTON — NASA has selected SpaceX to launch the last in a series of geostationary weather satellites that had previously been launched by United Launch Alliance.

NASA announced Sept. 10 that it awarded a contract to SpaceX for the Falcon Heavy launch of the Geostationary Operational Environmental Satellite (GOES) U spacecraft. The launch is scheduled for April 2024 from the Kennedy Space Center in Florida. The agency said the contract is valued at $152.5 million.

GOES-U is the fourth and final satellite in the GOES-R series of satellites, which monitor terrestrial and space weather from geostationary orbit. GOES-R launched in November 2016 and was renamed GOES-16, operating from the GOES East slot at 75 degrees west in GEO. GOES-S launched in March 2018 and became GOES-17, operating from the GOES West slot at 137 degrees west. GOES-T is scheduled to launch in January 2022 and will replace GOES-17 because of problems with that satellite’s main instrument, the Advanced Baseline Imager.

A spoonful of sugar opens a path to longer lasting lithium sulfur batteries

Posted by in categories: drones, energy, engineering, food, sustainability

Simply by adding sugar, researchers from the Monash Energy Institute have created a longer-lasting, lighter, more sustainable rival to the lithium-ion batteries that are essential for aviation, electric vehicles and submarines.

The Monash team, assisted by CSIRO, report in today’s edition of Nature Communications that using a glucose-based additive on the positive electrode they have managed to stabilize lithium-sulfur battery technology, long touted as the basis for the next generation of batteries.

“In less than a decade, this technology could lead to vehicles including electric busses and trucks that can travel from Melbourne to Sydney without recharging. It could also enable innovation in delivery and agricultural drones where light weight is paramount,” says lead author Professor Mainak Majumder, from the Department of Mechanical and Aerospace Engineering and Associate Director of the Monash Energy Institute.
