How bad would SpaceX’s Starlink constellation with 42k+ satellites be in terms of space junk and affecting astronomical observations?

To put it simply: Every professional astronomical society has statements of varying levels of condemnation on Starlink. Nearly everyone I know that does ground-based astronomy (and even a couple of astrophotographers) think the statements aren’t strong enough and want the project stopped dead/large tax placed on these swarms.

Once fully implemented, there’s essentially a 100% chance of satellites turning up in long exposures and it will be tons of added work trying to remove them (and realistically, the output will drop drastically). Optically, it’s possible to get around them (but not in the current Starlink plan) with more work/resources than professional astronomers have, but those working in non-visible light wavelengths are not so lucky. Radio astronomy will be dead as a field, SETI project dead, infrared will be a mess, exoplanet-hunting dead, asteroid detection dead.

Basically, we will be forced to use space telescopes only… Of which there are very few and the competitiveness of proposals will be through the roof. Given the high priority of space-based telescopes, there aren’t many “exploratory” type niche projects that can be carried out on low-interest targets, so we’ll be really limited about what we’re allowed to study as well. Considering most of us already work on shoestring budgets, I expect to see many people leaving the field to go become “data scientists” for consulting firms.

Don’t believe the SpaceX press releases, real astronomers are horrified at what this means for our research.

Inside Tesla’s Cybertruck that will enter production in late 2022 (VIDEO)

Now entering a new class of strength, speed, and versatility—only possible with an all-electric design. The powerful drivetrain and low center of gravity provide extraordinary traction control and torque—enabling acceleration from 0-60 mph in as little as 2.9 seconds and up to 500 miles of range. With the ability to pull near-infinite mass and a towing capability of over 14,000 pounds, Cybertruck can perform in almost any extreme situation with ease.http://www.youtube.com/watch?v=y-CWAZ9T30w

From rugged to refined, Cybertruck is completely adaptable for your needs. Prepare for every experience with a versatile utilitarian design — including onboard power and compressed air.

 

Elon Musk Has Buried Tesla With A Single Tweet

Summary

On April 13, Tesla CEO Elon Musk tweeted an acknowledgement that Tesla had over-automated its production lines and underestimated the value of human workers in auto assembly.

This revelation was unsurprising to auto industry experts, who have been making that very observation for years.

Musk has been a champion of ever greater automation and the “productizing” of vehicle manufacturing facilities; the reversal of tone goes back on years of statements.

With the supposed increased efficiency and margin improvements from full automation no longer on the cards, Tesla’s future looks increasingly bleak.

Elon Musk, CEO of Tesla (TSLA), made a big admission on the afternoon of April 13th. Apparently channeling the Friday the 13th horror spirit, Musk announced via tweet that the electric car manufacturer had over-automated its production process:

“Excessive automation at Tesla was a mistake. To be precise, my mistake. Humans are underrated.”

The tweet was a follow-on from an interview with CBS that aired Friday morning in which Musk talked about gutting much of the overly complex Model 3 assembly line:

“We had this crazy, complex network of conveyor belts….And it was not working, so we got rid of that whole thing.”

This admission represents a major reversal of virtually everything Musk and his team at Tesla have been saying about the Model 3 production process. And it signals a death knell for the Tesla bull case that ought to send prudent investors running for the hills – or taking up a short position.

Let’s talk about the various consequences of Musk’s admission:

“Productizing” the Factory Proves a Daunting Task

Gallons of digital ink has already been spilled on the subject of the beleaguered ramp-up of Tesla’s first mass-market vehicle, so there is little point in recapitulating all the problems that have occurred – and continue to dog the process. All that need be said to provide context for this article is that the ramp has still failed to hit its end-of-March production rate target of 2500 Model 3s per week, and that Musk claims to still be sleeping on the factory floor in order to deal with the continued issues.
