We’ve arranged a #society on #science and #technology in which nobody understands anything about science and technology, and this combustible mixture of ignorance and power sooner or later is going to blow up in our faces. I mean, who is running the science and technology in a #democracy if the people don’t know anything about it ? https://www.openculture.com/2022/10/carl-sagan-issues-a-chilling-warning-to-america-in-his-last-interview-1996.html

This time the problem was with the rocket, not the spacecraft https://www.washingtonpost.com/technology/2024/05/07/boeing-starliner-launch-valve-delay/

#Starliner #ULA

The #AtlasV rocket carrying #Boeing's new #Starliner space capsule will be rolled back to its hangar to replace a pressure valve, postponing the long-awaited first crewed test flight of the spacecraft for at least 10 more days, #NASA said on Tuesday https://www.reuters.com/science/first-crewed-test-flight-boeing-starliner-capsule-targeted-may-17-2024-05-07/

#Starliner has been delayed ⏳ again - until at least May 21 - over an issue with the spacecraft's propulsion system 🙄 https://www.reuters.com/technology/space/boeing-starliners-crew-debut-delayed-again-over-spacecraft-issue-2024-05-14/

The flight, which was originally scheduled for May 6, is now set for no earlier than 📆 May 25 https://www.washingtonpost.com/technology/2024/05/17/boeing-starliner-launch-delay-may-25/

#NASA has cleared #Boeing and #ULA to proceed with a 📆 June 1 launch attempt of #Starliner on a crewed flight test to the #ISS. https://aviationweek.com/aerospace/commercial-space/starliner-crew-flight-test-cleared-june-1-launch

Any more delay ⏳ could require the #AtlasV rocket to stand down to replace time-limited elements of its flight termination system. That, in turn, could lead to more delay thanks to activity at #ISS https://payloadspace.com/boeing-found-yet-another-design-flaw-in-starliner/

The #CMEs travel at different speeds but are expected to arrive together at Earth by late Friday, 📆 May 10 or early Saturday, 📆 May 11. When fast-moving CMEs overtake slower CMEs in front of them, shock waves of their collision "do a good job sparking #geomagnetic storms when they strike Earth's magnetic field." https://www.forbes.com/sites/jamiecartereurope/2024/05/09/prepare-for-northern-lights-in-the-us-this-weekend-after-intense-solar-activity-say-scientists/

Soon we will be putting at least an Eiffel Tower’s worth of metallic ash a year directly into the #ionosphere. Highly conductive materials can create charging effects and act as a magnetic 🧲 shield https://www.theguardian.com/commentisfree/2024/apr/16/dead-satellite-space-earth-magnetic-field

@Eka_FOOF_A her rpoint is "Unlike meteorites ☄️, which are small and only contain trace amounts of aluminum, these wrecked spacecraft are huge and consist entirely of aluminum and other exotic, highly conductive materials. And highly conductive materials can create charging effects and act as a magnetic 🧲 shield" (NOT the "space dust that is very similar to plain earth dust")

The war in #Ukraine 🇺🇦 has left a deep impression on Europeans, and they have seen the value of secure #satellite 🛰️ Internet. The difficulty is in how to get there. The continent does not have a reusable rocket like #SpaceX's Falcon 9, nor the capacity to rapidly build hundreds of complex satellites. There is the challenge of coordinating such a complex endeavor across many different constituencies https://arstechnica.com/space/2024/05/europes-ambitious-satellite-internet-project-appears-to-be-running-into-trouble/

Launch costs have fallen 95% 📉 (with another massive reduction expected in the coming years) thanks to reuse, improved engineering, and increased volumes.
