As the global climate continues to change and extreme weather events increasingly threaten regions all over the world, accurate weather forecasting is becoming more important than ever.
In a new study published in Scientific Reports, a research team led by Institute of Industrial Science, The University of Tokyo reports that weather forecast accuracy can be improved by several percentage p Rapid increase in global light pollution

Global light pollution has increased by at least 49% over 25 years, new research shows.
This figure only includes light visible via satellites, and scientists estimate the true increase may be significantly higher - up to 270% globally, and 400% in some regions.
The study, led by the University of Exeter, examined light emissions from 1992 to 2017.

The SpaceX mission Inspiration4 - the first all-private orbital spaceflight - lifted off from Florida on Wednesday night, carrying four civilians led by philanthropist and pilot Jared Isaacman.
The Falcon 9 rocket carried the Crew Dragon capsule into a mostly clear night sky as planned at 8:02 p.m. EDT from Launch Complex 39A at Kennedy Space Center.

Three Chinese astronauts have completed the country's longest crewed mission and started their journey home on Thursday after 90 days at the Tiangong space station conducting spacewalks and scientific experiments.
"The Shenzhou-12 manned spacecraft has successfully separated from the space station's core module," state broadcaster CCTV said Thursday.

Drowsy driving accounts for a large proportion of car crashes, according to the National Highway Traffic Safety Administration. So, you might think self-driving cars would fix that. After all, computers just don't get sleepy.
But today's vehicles are only partially automated, requiring the human driver to stay alert, monitor the road, and take over at a moment's notice. A new study conduct A gem of a lab will bring the world of quantum physics into the light

Transporting a single brick to Mars can cost more than a million British pounds - making the future construction of a Martian colony seem prohibitively expensive. Scientists at The University of Manchester have now developed a way to potentially overcome this problem, by creating a concrete-like material made of extra-terrestrial dust along with the blood, sweat and tears of astronauts.

A SpaceX Falcon 9 rocket carrying four space tourists blasted off Wednesday night from the Kennedy Space Center in Florida for the first mission to orbit the globe with an all-civilian crew.
A huge fireball illuminated the sky as the rocket's nine engines began to pull away from Earth at 8:02 pm (0002 GMT Thursday).

The explosion of wireless applications enabled by advanced radio technologies has placed access to a key natural resource, the radio frequency spectrum, at a premium.
In the United States and around the world, radio frequencies are allocated to a variety of services such as mobile broadband, broadcasting and navigation (GPS) that are now mainstream and widely used.

ESA astronaut Thomas Pesquet takes you on a tour of the International Space Station like no other. Filmed with a 360 camera, the Space Station 360 series lets you explore for yourself alongside Thomas’s explanation – episode four is NASA’s Quest airlock.
The Quest airlock is the Station’s smallest module, but it is vital for going on spacewalks. This is where the astronauts suit up into their spacesuits, prepare for the spacewalk and enter the airlock to go outside for maintenance, installing new equipment or science experiments.

Europe's Spaceport in French Guiana is performing the first combined test in preparation for the inaugural flight of Ariane 6, Europe's new generation launch vehicle.
This test confirms the operations and electrical and mechanical equipment required for integration of the upper part of the launch vehicle. The procedures are carried out in conditions representative of a launch campaign. A major step of this test involves the closure of the Ariane 6 fairing around the payload.
Preparations started in May 2021 with a de-risking campaign of the mechanical operations.
The fairing, built by Ruag Space in Switzerland, stands 20 m high and 5.4 m in diameter. It protects payloads from the thermal, acoustic and aerodynamic stresses on the ascent to space.
This combined test was performed using a new integration dock, composed of a large white frame, with two mobile platforms adjustable to any level and accessible by fixed stairs and platforms, developed by the French space agency, CNES.
The assembly building has two halls: one for integration of the fairing and another where the payload is stowed in the fairing.

Verifying that a satellite will resist the sheer noise of the rocket launching it into orbit is a very important test that every mission must successfully pass.
“Typically satellites are tested inside purpose-built reverberant chambers, such as ESTEC’s own Large European Acoustic Facility sometimes described as the largest and most powerful sound system in Europe,” explains ESA test facility expert Steffen Scharfenberg, overseeing the test campaign together with ESA mechanical engineer Ivan Ngan. A very powerful noise generation system produces a uniform noise field thanks to the reverberation on the thick concrete walls of the chamber.
