Europe's Spaceport in French Guiana is carrying out combined tests to prepare for the arrival of Ariane 6, Europe's next generation heavy-lift launch vehicle.

The first Ariane 6 fairing has already arrived at the Spaceport from Europe. It is 20 m high and 5.4 m in diameter and is being integrated with a mockup payload to test equipment and procedures inside the assembly building.

Ruag Space in Emmen, Switzerland manufactures each entire large half-shell in one piece from carbon-fiber composite which is 'cured' in an industrial oven. This reduces cost and speeds up production. Fewer parts allow horizontal as well as vertical assembly of the closed fairing and the launch vehicle, which is particularly important for Ariane 6.

A blue metal scaffold on the right of the picture, called the 'strongback," encases the fairing. There is one for each half-shell to hold each steady and to maintain the shape of the fairing while it is being raised vertical, and during assembly.

The mockup payload stands on its payload adaptor—the black cone. This is the interface between the bottom of the payload and the rocket.

A mission to explore energy transport in space using a NASA suborbital sounding rocket launching May 8, 2021, from NASA's Wallops Flight Facility in Virginia may provide a brief light show for residents of the eastern United States and Bermuda.

The mission is scheduled for no earlier than 8:02 p.m. EDT with a 40-minute launch window, Saturday, May 8. Backup launch days run through May 16. The launch may be visible, weather permitting, in much of the eastern United States from the Atlantic coast to the Mississippi River.

A four-stage Black Brant XII rocket will be used for the mission that includes the release of barium vapor that will form two green-violet clouds that may be visible for about 30 seconds. The barium vapor is not harmful to the environment or public health

The mission, called the KiNETic-scale energy and momentum transport eXperiment, or KiNet-X, is designed to study a very fundamental problem in space plasmas, namely, how are energy and momentum transported between different regions of space that are magnetically connected?
