So far, their military structure has been amazingly bad. Ukraine has been really good at using modern tactics, which has been just important tot their success so far as having modern weapons. But Russia has also contributed to that by having horrible tactics, horrible logistics, and horrible leadership. A future…

Agree that Russia owes some serious reparations, but I’m also wary: Post-WWI reparations are often cited as a contributing factor to the rise of the Nazi party in pre-WWII Germany. I hope for better results in the future, but we may have to settle for having Ukraine be whole again without all the punitive measures…

This part of the rocket apparently uses a solid fuel, which should have been fully combusted by the time it came down. It is not the kind that uses any of the really toxic hypergolics, but any remnant could be slightly toxic to handle.

It’s simpler than that. She can try to buy it from Eric, at whatever price he demands. He might say no.

She had that option back in March, for much less than the auction price. Too late now. The gavel dropped, it’s sold.

Very carefully? I’ve been following Voyager’s operations (as reported in media) since the 90's so I’m familiar with the how we got here for the most part, and many of the magic tricks, close calls, and compromises in that time. And it still amazes me we can pick up that little 23-watt transmitter from so far away.…

To that end, SpaceX has also constructed a metal diverter beneath the OLM. This infrastructure (both the water deluge system and the giant metal plate)

My question is how they know it’s only “2 degrees” off if they are not getting data from it?

IIINNPUT!

Depends how good your simulations are, and how much delta-V you can dedicate to lowering the perigee into thicker atmosphere. The Apollo missions were consistently able to land within 3 miles of their target because they used a very specific reentry path, with a perigee well inside the atmosphere. Falcon 9 boosters…

Looks like you need to be in Iceland if you want to see it. It will be travelling from north to south for the Atlantic splash.

Edit: This satellite is in a polar orbit, and is planned to reenter over the north Atlantic, which does give it a few thousand miles (from north to south) of error range. It also means that nobody will see it reenter, unless maybe they are in Iceland.

In a word, Delta-V.

Because the oval of uncertainty is larger than any current battlefield? I’m actually surprised they chose the Atlantic. Usually these kinds of events are targeted to the south Pacific, multiple thousands of miles away from any inhabited land.

We still use radar, often combined with ADS-B data and transponder data, for tracking aircraft. Many small planes don’t have ADS-B, so ATC uses radar as their primary data source.

Water vapor in the troposphere can have a greenhouse effect, but this source says that water emitted from near-surface sources does not.

Water evaporation is one of the few ways to cool that doesn’t need toxic  refrigerants and is relatively power efficient.

It says they use non-potable water when possible. This typically means either grey water or recycled water.

Making it bigger wouldn’t help if the surface can be damaged as it was. So they are doing something completely different with the water jets and metal. 

They tried concrete underneath there, and it failed.
