JILA physicists have measured Albert Einstein's theory of general relativity, or more specifically, the effect called time dilation, at the smallest scale ever, showing that two tiny atomic clocks, separated by just a millimeter or the width of a sharp pencil tip, tick at different rates.
The experiments, described in the Feb. 17 issue of Nature, suggest how to make atomic clocks 50 times NASA's IXPE sends first science image

In time for Valentine's Day, NASA's Imaging X-Ray Polarimetry Explorer which launched Dec. 9, 2021, has delivered its first imaging data since completing its month-long commissioning phase. All instruments are functioning well aboard the observatory, which is on a quest to study some of the most mysterious and extreme objects in the universe.
IXPE first focused its X-ray eyes on Cassiopeia Psyche, the iron giant of asteroids, may be less iron than researchers thought

The asteroid 16 Psyche, which NASA intends to visit with a spacecraft in 2026, may be less heavy metal and more hard rock than scientists have surmised, according to a new study by researchers from Brown and Purdue universities.
Psyche, which orbits the sun in the asteroid belt between Mars and Jupiter, is the largest of the M-type asteroids, which are composed chiefly of iron and nickel a Studying the next interstellar interloper with Webb

One of the most exciting findings in planetary science in recent years is the discovery of interstellar objects passing through our solar system. So far, astronomers have confirmed only two of these interlopers from other star systems - 1I/'Oumuamua in 2017 and 2I/Borisov in 2018 - but many, many more are thought to exist. Scientists have had only limited ability to study these objects once disc Quantum tech in space?

Operating quantum technology in challenging environments, such as space, has moved a significant step forward after physicists working at the University of Sussex have developed a monitoring and control system blueprint for quantum devices and experiments.
The system is presented in a peer reviewed paper published in Quantum Science and Technology. The paper details how the University's Qu Homegrown spacecraft is putting Perth on Space Race map

Perth researchers made history when they sent the first WA designed and built satellite into space last year.
The Binar-1 - named after the Noongar word for fireball - was developed by Curtin University's Space Science and Technology Centre.
The Binar Space Program team plan to deploy six more locally made satellites in the next 2 years.

Eutelsat Communications and Marlink, the Smart Network Company, have agreed to extend their Global Maritime Partnership, initially signed in 2019, to support expansion in Africa and the Middle East (Red Sea and the Gulf) and to integrate the Americas and Asia into the portfolio of Eutelsat satellite capacity used by Marlink.

An Earth science instrument selected by NASA several years ago to fly as a hosted payload on a commercial communications satellite may instead fly on a standalone spacecraft because of a lack of hosting opportunities.

James Webb telescope going through cooling process
Wednesday, 16 February 2022 16:05 Write a comment
Cooling things down in space is trickier than it might sound. But that is exactly the process the James Webb telescope is going through right now. Getting down to cryogenic temperature is imperative for its infrared imaging systems to work correctly. While the telescope has already started, it will be another few weeks before the process is complete and it's ready to start capturing its first groundbreaking infrared images of the universe.
That might seem like an exceptionally long time to cool something down, but it's all part of the difficulty of doing so in space. The first tricky point is getting out of the sun, which can heat equipment up to blistering temperatures if it is exposed to direct sunlight. Luckily, James Webb has a specially designed sun shield to keep it out of direct sunlight.
The rest of the telescope's instruments have been cooling since the sunshield was deployed several weeks ago.
