If SpaceX gets Starship to the same frequency and reliability as Falcon 9, the market for other launch providers is almost gone. 60 Starship launches a year would outclass all other launch providers combined by an order of magnitude, at a lower combined cost.

And you know what 2 dimensional means right? A truly 2 dimensional object would have zero thickness, zero volume and thus zero mass.

Yup. That was the one. The engine killed a few characters off after an accident during a test.

A test was done back in the day. Equivalent to a few tons of TNT.

Relatively short burn times. Thus only a small radioactive inventory of fission products.

Just uranium. Like, what is found naturally all over the place.

Texas. Basically, Dallas/Fort Worth and to the south.

I am an Eclipse Ambassador (education project) and have been working on planning for this since 2018. I have a number of sites all over Texas, planning for inclement weather. My primary site is near the centerline, with 4:15 of totality. It is family land, and will be available to our local astronomy club members (and a few professional astronomers coming to town). I will also be doing a live YT broadcast from there, with 4K/6K cameras streaming live and recording for later.

Secondary and tertiary sites are located south and west of me - Lampassas, Fredricksburg, Kerrville, Vanderpool. I have contacts with clubs in those areas, and I want to have reciprocal agreements - if it is cloudy here and clear there, we have places to go, and vice versa.

I have contacts with an eclipse-chasing group coming from Europe. They are wary of going to Mexico due to the drug violence, and without knowing anyone there they do not want to show up and find out they were scammed and have nowhere to go. So, Texas it is for them.

This is the site you want for planning:
