Combined tests start for Ariane 6 at Europe’s Spaceport

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 was performed using a new integration dock, composed of a large white frame, with two 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.

Rapid increase in global light pollution

Exeter UK (SPX) Sep 15, 2021
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 findings show differing r

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

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. But the increasing deman

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). Around 12 minutes later, the Dragon capsule separated from the rocket's

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. In

The novel design for a next-generation diamond sensor with capabilities that range from producing magnetic resonance imaging (MRI) of single molecules to detecting slight anomalies in the Earth's magnetic field to guide aircraft that lack access to global positioning systems (GPS) will be developed by a collaboration of scientists led by the U.S. Department of Energy's (DOE) Princeton Plasma Phy

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
