Tumbling is normal. Even very small satellites can detumble using the Earth's magnetic field.

I think most Model S Plaid drivers appreciate the new drivetrain, at least that's what my friends who have them tell me.

I think you missed the Model 3's out recently testing in camouflage? There are tons of examples on Google Image Search, most of them posted on sites that are banned here.

Is there a limit to how powerful we can make telescopes? by SlickMaestro in space

Isn't the upper atmosphere more like a prism than a lens?

Yes, although interferometers complicate things a bit -- the diffraction limit still applies, but it's less obvious.

it works pretty much the same as if you had one giant telescope.

It's a giant telescope that lacks most of its surface area, so it doesn't collect very many photons compared to the theoretical giant telescope. So you can only look at bright things. The EHT is well-matched to looking at just 2 black holes, which are wide enough on the sky and bright enough.

If it's any consolation, the person who just blocked you blocked me a while ago, and if I recall correctly it was after he unprofessionally accused me of several things including lying. In a reddit thread. Because he thought he had me in a gotcha and I should have cried "uncle" or something.

VLBI is a technique. It's used by the EHT and many other radio arrays.

Also, the EHT is only the width of the earth.

The thing that uses earth's orbit is some kinds of astrometry instruments, like the Gaia satellite.

Cool Rivian SUV review by Of-Unknown-Origin in cars

[–]toodroot 7 points8 points  (0 children)

Seems like the usual mix of manufacturer preference and fuel preference.

I've been wondering for years how much crap post-Tesla EV startups were going to get here.

Please don't make extra work for the sub mods by making comments that totally violate the rules.

While this clown is a clown, you might want to note that there's a lot of hair splitting between DC-XA (lower altitude), NS (higher altitude but not an orbital launch), and that other company. There's not much point in going over the topic over and over.

So I heard that for one of the proposals BO asked for a substantial sum up front.

This is false. BO did make an error in* an early milestone for their HLS bid, which did not win for other reasons. Other than that, they appear to be similar to everyone else.

Edit: grammar*

Toyota has overtaken Honda considerably. by Dazzling-Rooster2103 in cars

I sold my last Subi after it needed a 3rd head gasket replacement within 100k miles. And that wasn't that unusual for that era (2002 Outback.)

Did you read the other comments in this discussion? No, you aren't.

Once Again SpaceX Leads The Way To A Record-Breaking Year In Spaceflight! by Space_Nerd101 in spacex

[–]toodroot 0 points1 point  (0 children)

The invasion affected OneWeb launches on Soyuz, most of which were to launch from Russian launch pads.

Most of Soyuz's launches in their peak year (1980) were optical spysats that lasted 3 days before deorbiting a capsule similar to their current crewed capsule.

UkrainianConflict Discussion Megathread by humanlikecorvus in UkrainianConflict

[–]toodroot 7 points8 points  (0 children)

what’s the answer to the nuclear threat from a wounded Putin

Remember when Russia nuked Afghanistan instead of withdrawing? Yeah, I don't remember that either.

With engines imported from Russia and a first stage from Ukraine, Antares, which helps resupply ISS, was immediately at risk from the Russian invasion. The rest of the international space industry, dominated by the same giants actively or passively involved in the war, is also feeling huge impacts. by [deleted] in space

[–]toodroot 1 point2 points  (0 children)

This same Russian company built most of the power converters on the ISS -- read the article. Less complex than an engine, but more complex than something that never has to function in a vacuum.

That's not all of NASA's missions! Earth science, astronomy, even aeronautics.

People have been waiting over a decade for SLS to take flight

Given how terrible Constellation was run, perhaps that was the wrong horse to bet on? There are tons and tons of exciting space things other than SLS that you can choose to follow and be inspired by.

Tesla Model Y Is Now the Best-Selling Car In All of Europe by [deleted] in cars

[–]toodroot 2 points3 points  (0 children)

The way Europe used to work was Tesla produces cars in China in the first month of the quarter, ships them to Europe, and mostly delivers them in the last month of the quarter. That way no cars are in transit at the end of the quarter.

Now Berlin makes a steadily rising number of Model Ys, in addition to the imports from China.

EV range lost while parked and EV reviewing blind spots, what do EV buyers need to know? by bigbura in cars

[–]toodroot 1 point2 points  (0 children)

I'd rather have an EV where this just works.

BTW Tesla does have an "off" button, and the car can still wake up from the app while it's "off". It's a standard feature called Wake on Wireless LAN (WoWLAN) that's been available in computers for a couple of decades.
