Thank you! This is why I have a very mixed opinion of Louis Rossmann. His heart seems to be in the right place, but he provides extremely slanted view of reality.

I had a hell of a time trying to find a pill planner that didn't start on Sunday. I was ready to 3D print one when I found one that's circular.

It would increase operational costs. The satellite lifetime is limited by propellant capacity (especially at the low altitudes where Starlink operates). Mercury thrusters would be significantly less efficient than the krypton thrusters they

Starship's engines burn methane.

The torch would, most likely, be for emergency methane venting. They had previously used a torch for burning gaseous methane during de-tanking, but have since switched to a condenser to cool it back to a liquid. There would essentially be n

All of those would need to get approval by the Texas DOE.

The pretreatment plant is for extracting pure methane from natural gas. That is in the document.

What it ignores is that to perform the maximum number of launches permitted under this new license will consume around 1% of the methane this would produce. This equipment will be be used, at most, a few hours every month, but he's pro

His arguments don't make sense. This environmental study is being performed so that SpaceX can make five orbital launches per year from Boca Chica, but ESG Hound's numbers would be for more than ten per week. I've pointed thi

Not just complex specs. Some of them are proprietary.

There are already good solutions to this issue. In particular, simply placing the app package in a zip file, then checking to see if it's installed correctly when opened.

If there isn't a backup, it should at least notify the user of the error. But the OS would know about backups, since it has a built-in backup system. Also, I wouldn't be surprised if Apple adds a cloud-based backup for macOS once

That is little different from a flat-out lie.

The downloads page has links to snapshots of the source. Edit: Though I suppose the tools are only provided as binaries.

Not quite reversal since it doesn't negate the vertical motion, but yeah. Definitely the most significant of the three burns. Though it's not quite that simple. Based on the trajectory of last week's launch, they're actu

The third burn here is also a suicide burn. The first one is to change its path and the second is to prevent it from falling too fast.

Compare the amount of force it takes to crush an aluminum can from the sides vs. from the top and bottom. A rocket is the same basic shape and material.

There are a total of three burns: 1. Alter the path so the parabolic arc goes back to the launch site. 2. Braking burn during descent to minimize atmospheric stress. 3. Landing burn (AKA "suicide burn") to slow the vehicle enough

It would require significantly more fuel to get the stage to even the Gulf coast of Florida (much less the Atlantic coast) than it would take to return to Brownsville. Additionally, Brownsville launches will almost certainly be aimed betwee

Nor is it for Falcon 9. They're launching them as fast as they can build them, and have a significant payload backlog.

The component of the URL you check when avoiding phishing attack (the domain) is still displayed.

That's actually fairly old behavior. If you copy the full contents (which is selected by default) it includes the protocol.
