Video: Ariane 6 passes tests in preparation for first flight
Friday, 05 April 2024 15:51Europe's next rocket, Ariane 6, passed all its qualification tests in preparation for its first flight, and the full-scale test model has been removed from the launch pad to make way for the real rocket that will ascend to space.
The test model at Europe's Spaceport in Kourou, French Guiana, stood 62 m high. It is exactly the same as the "production model" Ariane 6 rockets that will soon be launched, except that its boosters do not need to be tested as part of the complete rocket, so the boosters are not fueled.
Teams preparing Ariane 6 for its inaugural flight successfully completed for the first time a launcher preparation and countdown sequence, on 18 July. Representatives of ESA, Ariane 6 prime contractor ArianeGroup and launch base prime contractor and test conductor CNES completed important objectives for system qualification and performed a series of actions fully representative of a launch chronology.
The launch simulation included the removal of the mobile gantry, the chill-down of ground and launcher fluidic systems, the filling of the upper and core stage tanks with liquid hydrogen (–253°C) and liquid oxygen (–183°C), and at the end of the test, the successful completion of a launch chronology up to the ignition of the Vulcain 2.1 engine thrust chamber by the ground system.

First ‘glory’ on hellish distant world?
Friday, 05 April 2024 07:00
For the first time, potential signs of the rainbow-like ‘glory effect’ have been detected on a planet outside our Solar System. Glory are colourful concentric rings of light that occur only under peculiar conditions.
Data from ESA’s sensitive Characterising ExOplanet Satellite, Cheops, along with several other ESA and NASA missions, suggest this delicate phenomenon is beaming straight at Earth from the hellish atmosphere of ultra-hot gas giant WASP-76b, 637 light-years away.
Seen often on Earth, the effect has only been found once on another planet, Venus. If confirmed, this first extrasolar glory will reveal

Friday, 05 April 2024 06:36Total solar eclipse forecast: Will your city have clear skies Monday?
Thursday, 04 April 2024 20:20Some who hope to witness Monday's total solar eclipse may see the sun obscured by clouds instead of by the moon.
There's still plenty of time for forecasts to change, but meteorologists predict that eclipse day storms could blanket parts of the path, which stretches from Mexico and Texas through Maine and parts of Canada.
If clouds don't get in the way, viewers in the path wearing eclipse glasses will see the moon begin to slowly cover the sun until it is completely blocked, a period of darkness called "totality" during which temperatures drop and the sun's corona will be visible.
What's the forecast along the eclipse's path?
Clouds are expected in much of the eclipse's path Monday thanks to storms that are moving across the central U.S.
