Climate emissions shrinking the stratosphere

A stark signal of the climate emergency and the planetary-scale influence that humanity now exerts
Humanity's enormous emissions of greenhouse gases are shrinking the stratosphere.
The thickness of the atmospheric layer has contracted by 400 metres since the 1980s, and will thin by about another kilometre by 2080.

Webb’s golden mirror wings open one last time on Earth

The world’s most powerful space science telescope has opened its primary mirror for the last time on Earth.

As part of the international James Webb Space Telescope’s final tests, the 6.5 meter (21 feet 4 inch) mirror was commanded to fully expand and lock itself into place, just like it would in space. The conclusion of this test represents the team’s final checkpoint in a long series of tests designed to ensure Webb’s 18 hexagonal mirrors are prepared for a long journey in space, and a life of profound discovery. After this, all of Webb’s many movable parts will have confirmed in testing that they can perform their intended operations after being exposed to the expected launch environment.

Making the testing conditions close to what Webb will experience in space helps to ensure the observatory is fully prepared for its science mission one million miles away from Earth.

Commands to unlatch and deploy the side panels of the mirror were relayed from Webb’s testing control room at Northrop Grumman, in Redondo Beach, California. The software instructions sent, and the mechanisms that operated are the same as those used in space. Special gravity offsetting equipment was attached to Webb to simulate the zero-gravity environment in which its complex mechanisms will operate. All of the final thermal blanketing and innovative shielding designed to protect its mirrors and instruments from interference were in place during testing.

Webb is an international partnership between NASA, ESA and CSA. The telescope will launch on an Ariane 5 from Europe's Spaceport in French Guiana.

So the Pluspora pod may be closing!?!? I've found a new home so I'm posting a new intro...

I'm not #newhere just from a new pod. I am currently one of the #CheckIn hosts and my interests are #dogs, #science, #science-fiction, #Canada. I'm also really into #tech and revisiting things I used to do as a youth...like maybe playing the recorder just because.

And now this...Canadian Cobra Chickens

Dieses Resultat sollten all jenen zu denken geben, die probieren, die Ansicht von anderen Menschen nur mit dem Hinweis auf Fakten zu ändern. (...) Echte Überzeugungsarbeit braucht mehr als nur die richtige Formel.

Lessons learnt from simulated strike








In an alternate reality playing out at this year’s international Planetary Defense Conference, a fictional asteroid crashes over Europe, 'destroying' a region about 100 km wide near the Czech Republic and German border. The scenario was imagined, but the people who took part are very real, and the lessons learnt will shape our ability to respond to dangerous asteroids for years to come.

Forest measuring satellite passes tests with flying colours








With challenges imposed by the Covid pandemic, engineers building and testing ESA’s Biomass satellite have had to come up with some clever working methods to keep on track whilst adhering to safety rules. The result is that the satellite structure is not only complete, but has also undergone a series of demanding tests to ensure it will withstand the rigours of liftoff – all bringing the launch of this extraordinary forest carbon mapping mission one step closer.

ESA to live tweet asteroid impact exercise








For almost a decade, world asteroid experts have been meeting every two years at the Planetary Defense Conference and pretending an asteroid impact is imminent. Why? To prepare for the unlikely – but plausible – scenario in which this comes true.

https://en.wikipedia.org/wiki/Proton-enhanced_nuclear_induction_spectroscopy
Proton-enhanced nuclear induction spectroscopy (PENIS), also called cross-polarisation (CP), is a nuclear magnetic resonance technique invented by Michael Gibby and Alexander Pines (who named it specifically for the inappropriate acronym) while they were graduate students in the lab of Professor John S. Waugh at the Massachusetts Institute of Technology.
