Exclusive: #SpaceX, #ULA to clinch multibillion-dollar #Pentagon launch contract

#ElonMusk's SpaceX & United Launch Alliance are expected to each win a #US #SpaceForce rocket launch contract on Friday worth billions of dollars over the next several years to send some of the Pentagon's most sensitive #satellites into #space, acc/to 2 people familiar w/the procurement decision.

Mastodon! I'm delivering a talk to a couple of grade 9 classes in a month on the use of space (mainly satellites, but probes to other planets, comets, etc., will be included).

How does your work benefit from satellites?

I'm thinking of a direct use of the data, as opposed to stuff like “internet access” or “my bank relies on satellites to transfer my grant money from one account to another” 😄

Anecdotes, rants, personal stories are all fair game 😊
(To the inevitable suggestion that I just Google this, yes, I can, and have, but I want the human element - I want to be able to say "someone I ‘know’ uses satellites for their job, and this is what they like about the tech”)

Hashtag suggestions are welcome.
(Also - question: Does Mastodon discriminate hashtags with different capitalization? Are #Astronomy and #astronomy functionally different? We *really* need some kind of ISO standard 😉)

"With over 34,000 large debris pieces in orbit and millions of smaller fragments, the threat of collisions and the #KesslerSyndrome looms large. International cooperation, stringent regulations, and technological solutions are proposed to address the crisis, emphasizing the need for a comprehensive global framework to ensure #SpaceSustainability for future generations."

🚀 The Center for Space Environmentalism (CSE) has launched!

🪐 CSE is a group of scholars and experts who inform and advocate for issues pertaining to the protection of the increasingly crowded space environment. It is intended in part to counter the prevailing narrative about the 'inevitable' commercial development and exploitation of outer space. We welcome dialog and interaction with anyone interested in these topics.

💪🏼 I am proud to participate in this effort with my colleagues @salvabara, @planet4589, @sundogplanets and others.

In the next few months, from its perch atop a mountain in Chile, the Vera C. Rubin Observatory will begin surveying the #cosmos with the largest camera ever built.

Every three nights, it will produce a map of the entire southern sky filled with #stars, #galaxies, #asteroids and @supernovae — and swarms of bright #satellites ruining some of the view.

Swarms of satellites are harming #astronomy.

Here’s how researchers are fighting back.

#ElonMusk’s #SpaceX Starship #Rocket Breaksup & Disrupts Florida #Airports

But sure yeah put this #SpecialK Presidential Adviser in charge of #AirTrafficControl for airplanes & sure, throw in space #satellites too.

Video showed the upper stage of the most powerful rocket ever built spinning out of control in #space, a repeat of an unsuccessful test flight in January that led to debris falling over the Caribbean.

From now on, American #satellites will see #russian #bombers carrying #missiles taking off, bound for #Ukrainian hospitals, critical power and transport infrastructure, and they will intentionally choose to sit on their hands rather than warn #Ukraine that it’s coming.

Immediate impacts from the total #US shutdown of intelligence sharing to Ukraine will be wide-ranging, and Russian air strikes targeting civilian infrastructure will likely become more effective.

#Musk’s business interests…have prompted concerns about #ConflictsOfInterest as he makes important decisions in DC.

Wed, #PublicInterest groups expressed concern that #HowardLutnick’s plans to change the #broadband program will benefit Musk.

“Fiber broadband is widely understood to be better than other internet options — like #Starlink’s #satellites — because it delivers significantly faster speeds,” said Drew Garner, dir of policy engagement for nonprofit Benton Inst for Broadband & Society.

#Congress created the '#Broadband #Equity, #Access & Deployment Program' in 2021 to extend broadband to the most remote areas of the nation. The #Commerce Dept came up w/standards & rules for states & territories applying for the funds—including the preference for fiber-optic broadband, to provide fast #internet speeds.

#Musk, #Trump’s adviser & #DOGE leader, is chief exec of #SpaceX, the rocket co that makes #Starlink. Starlink uses low-altitude #satellites to beam internet service to dishes…

Active #satellites 🛰️ must perform an increasing 📈 number of #collision avoidance manoeuvres to dodge out of the way of other satellites and fragments of #SpaceDebris. Another factor is the high level of solar ☀️ activity which can often cause increased atmospheric drag. If we extrapolate current trends into the future, catastrophic collision 💥 numbers could rise 📈 significantly esa.int/Space_Safety/Space_Deb

The layoffs also upend the agency's core function of #licensing commercial imagery #satellites. By Friday, companies seeking licenses or asking #regulatory questions by email were met with a response stating all those communications will be handled by #NOAA lawyers….

"This is a temporary arrangement to address continuity of operations as no senior personnel remain in the office due to ongoing reductions in force," the email read.

"These are like air traffic controllers for #space, they handle space traffic coordination to prevent collisions," one of the sources said, adding the #layoffs come at a bad time given the number of collision notices sent out. A collision notice is an alert that a satellite could collide w/another object in space.

"We are not talking a few dozen per year. We are talking tens of thousands," the source said. "It's like a game of chicken up there."
