SpaceX pays for service of ~14k terminals out of 25k and wartime service uses a lot more resources than regular business or residential grade. https://twitter.com/elonmusk/status/1582523481345835008

$4,500/month is a bit less than Starlink maritime at $5,000/month. I can't imagine it's cheap to provide the support needed for a warzone. There aren't any similar services with public numbers to compare this cost t

The beam hopping (TDM) part of the article is similar to satellite handover. There's a lag before a beam returns to a location or a new beam is over a location, and the beams can't overlap (nco=1).

Well Shotwell said on on March 22nd France and Poland donated, but the US didn't. Several days later on April 5th USAID announced a US government deal, so she was right at the time. The headline is extremely deceptive. Wapo is owned b

On the light pollution point, twilight is the worst time for satellite brightness, but as the satellites enter the Earth's shadow their brightness rapidly diminishes. Some estimates are 10%-30% data loss during twilight for Vera Rubin

The speeds Starlink will deliver are 2G speeds/device. They said 2-4Mbps/cell, and a cell is a wide area. I think it will have continuous coverage once the constellation reaches a certain size. AST SpaceMobile is planning 4g or 5g

A study was done on alumina in the atmosphere and 5,000 tons/yr doesn't seem dangerous. The study notes that because of the 3.8 g cm−3 density it falls quickly compared to other particles. The density is much higher than the chlor

And of course their MoD claiming in this attack "Aviation equipment at the airfield was not damaged" when satellite images show they've lost multiple aircraft. On the small scale, they've been caught moving the wreckage

It's deceptive to compare the two since the shuttle really is good almost exclusively for ISS missions, Hubble repair, etc (unique Canadarm capability) while F9 is the cheapest there is for Satellite launches at $2,720/kg. It isn&

Both those videos use wildly wrong numbers. There are no plans to use F9 for the entire constellation. SpaceX told the FCC they will use Starship (launch 200-400 sats at once) for the gen 2 constellation, which is 30k satellites. Thunderf00

Actually, it is. It's expected to launch around Q2 2022. The NEPA FAA PEA is going to be decided upon on February 28th then if they get the greenlight a launch attempt will happen a couple months after that. For commercial launches, th

Right now nobody claims it's making money. Musk himself said gen 1 is "financially weak". They have 600k+ preorders and geo satellite people are very happy with it, which is a couple million users mostly in the US just from t

The author says they don't mind rocket emissions. The problem is with the 250MW power plant that is allegedly being added to the PEA without many details and incorrect emission numbers. No mention of a gas pipeline even though that is
