Wait ‘til you see Intercourse, Pennsylvania.

I mean, it WAS a racecar.

Hacking around on the drums with some garage band, I think.

My favorite XKCD What If is the .9c baseball pitch. Of course, it has the relativistic kinetic energy of a small nuclear weapon.

First, the model rocket engine thing (black powder is about 80s Isp)

BTW, I MADE A MISTAKE! Not doing logarithms in Excel very often, I assumed LOG() was natural. LN() is natural. That changes my calculations to about 3,250 kg for 40k orbit change and 48,000 kg for the 220 m/s change for a 400km orbit change.

BTW, cheated on this one to do it quickly by using an online Hohmann orbit calculator. Hohmann transfer from 400km to 440KM is 22.56 m/s, or about 7,500kg of fuel assuming 421MT non-propellant mass (I’m assuming 420MT ISS and 1T orbital booster/tug). Not exactly a ridiculously large amount to launch to orbit.

OH, I HADN’T READ THE SPACE NEWS ARTICLE YET! They stated that they’re going to an 800 km orbit. They have already calculated out that this would require 220 m/s delta-V, which they claim is the same as re-entering it. Using an online Hohmann orbit calculator confirms this (I can longhand it out tonight if you’d…

What in?

I would also point out that the ISS is raised periodically already to account for orbital decay. This is done using a fraction of the propulsive power of a Progress cargo ship (just firing its engine for about 15 minutes). It doesn’t take a lot of Delta-V to overcome orbital decay. In fact, it’s quite a bit harder to…

Lessee, Michael Griffin has a BS in Physics from Johns Hopkins, a MSE in Aerospace Science from Catholic University of America, and a PhD in Aerospace Engineering from Maryland.

If you look at a rocket, fairly little of its losses are due to aerodynamic drag. Pretty much any rocket needs to generate some 9,000 M/S of delta-v or so to get to low Earth orbit. I’ve read that the Saturn V lost less than 50 M/S due to aerodynamic drag losses. Some rockets are higher, but not radically so.

Naah, you want these execs to go away peacefully, not fight for their lives. If it costs a few golden parachutes, so be it. I understand the desire for accountability, but let’s just get rid of them.

One of the possible benefits of buying Spirit back is that it increases the possibility that Pat Shanahan might become the CEO of Boeing. A lot of analysts believe that he might be one of the best candidates for the Herculean task of turning Boeing around.

Do you know how new it is? I live a couple miles from a Buc-ee’s, and there are several more in my metropolitan area, and I’ve never seen it that crazy. Is it new? If so, maybe there was still some novelty factor. I’ve certainly never seen bathroom lines, as mentioned in the article.

This only makes sense if this person’s only experience with Buc-ee’s coincided with the buses of the Allen, Texas, high school marching band (700-1,000, depending on whether it’s their halftime or competition show) stopping at the same Buc-ee’s at the same time.

Nice idea, but I have a hunch that there are enough Fox bodies leftover and aftermarket parts that you can do your own modern take on one (or maybe pay someone to help you/do it for you) for what it would cost for a continuation series.

While not road legal, Ferrari will sell you a track-day version of their comparable 499P, the 499P Modificata. But if you actually want to drive it, I think you’re limited to their specific track days in Italy.
