Mad Rocket Scientist

Tell the nearest teacher or person in charge that you felt really sick and still feel bad, and you want medical attention. (From a on-school nurse if possible). If they can't help, ask your parents or a friend (depends on your situation) to drive you to a doctor if you continue feeling bad, or home, as long as there's someone to keep an eye on you and help you if you start to feel bad again. Don't feel like you have to be in school, your health is more important.

25_KSP.zip My first surviving KSP install. Has the saves and screenshots from previous installs 90_KSP.zip .90 install 1_0_5_KSP.zip 1.0.5 install 1_1_KSP.zip 1.1 install KSP_112.zip 1.1.2 install KSP_113.zip 1.1.3 install KSP_12.zip 1.2 install ksp-win64-1.3.1.zip 1.3.1 install KSP_RO 1.1.3 Realism Overhaul main install KSP_RO_TEST 1.1.3 Realism Overhaul secondary install with a much lighter mod load. Also meant for testing my own mod KSP_RP 1.2.2 install with mods for a role-play like challenge (the challenge ended up dying, as did the reboot) KSP_test 1.2.2 install for testing my own mods with a clean install KSP_1_4 1.4 main install KSP_1_4_1 1.4.1 main install KSP_1_4_4 1.4.4 main install KSP_1_4_5 1.4.5 main install, lightly modded (only 1.5 gb gamedata) KSP_1_4_5_modded 1.4.5 secondary install, heavily modded (3.25 gb gamedata) for a challenge And that's it. I haven't installed anything past 1.4.5.

That seems like it would be uncomfortable for the passengers, especially since they experience G's from two directions at 180 degrees apart. If you mounted the fins at 120 degrees apart, you could get close to that by only rolling 60 degrees, requiring much less extra TPS and reducing the discomfort. Instead of full g-load both eyeballs in and out, you have full g at 30 degrees to the side of eyeballs in. (Assuming the passengers are lying down in line with the ship)

Oh, I forgot the most powerful part of the poodle: You can mount it inline on 1.25m stacks without any drag penalty, so it is one of the best SSTO engines.

The Wolfhound is an upgrade in every way over the Poodle. It even edges out the NERVA in many cases. (See the plots further down in that thread)

This: And this:

https://i.redd.it/zg9lfqobgwm11.jpg During the 2018 announcement, they said that you could pull out 2 of those aft cargo pods at a time to upgrade a single of the outer SL raptors to Vac. I was suggesting removing all of them and adding a ring of 6 more SL raptors to the BFboosters.

That makes sense. I'm not sure whether to be relieved that that is the easier solution or concerned that it is. Right, so I'm essentially dealing with the translational and rotational forces separately. My calculus is too weak to even derive the velocity Verlet, so I'll probably do the same thing I did for that: look up how it is used in simulations and try to understand the formula and code itself, not the derivation. How should I deal with local rocket coordinate systems? The simulation takes in the center of mass of the entire vehicle, but the CoM's relative position within the rocket changes throughout the flight. I was thinking of defining the locations of all the parts relative to the arbitrary origin, then computing the relative position from that to the CoM, and moving the origin by that much every time step. So the CoM is globally simulated, then the origin is defined relative to the CoM, then all the parts are defined relative to the origin. But is that just over complicating things?

If I model the rocket engine as an object with a location relative to the rocket's origin, where does the CoT go? At the origin of the engine object? Or does it really matter? EDIT: How should I calculate the CoT from the position and rotation of multiple engines?

What if the BFS-boosters have all the cargo pods replaced with SL raptors?

Congrats on having a published NASA report! Is it called "The Effect of Constrained Cruise Altitudes on Fuel Usage, NOx Production, and Flight Time for Commercial Aircraft?" As far as I can tell, it's not available anywhere on the internet.

That doesn't sound counter-intuitive though. I like that idea. I would love to see BFR turn into one of those great very early shuttle concepts. Not because I think they would work better, but because they look great.

EDIT: The building that the Brick Store is buying appears to still have a furniture showroom and car shop in it. I wonder if they were bought out.

Time for a new desktop background: Re: Zubrin SFS That would be an amazing idea, but I'm inclined to think that the slight delay in getting humans to mars in developing the BFR is worth it. On the other hand, if BFR takes a lot longer than expected it may look better in retrospect. I do I like the idea of using BFR to launch a Mars Direct mission. EDIT: I feel bad about Zubrin being so overshadowed by SpaceX and Elon Musk too. He really was talking about all this stuff way before Musk.

That is a great launch video! Are you tracking the launch by hand?

You might enjoy the Foundation series by Isaac Asimov, if you haven't already read it.

I would have expected the peak to be during the 1.0 release (I miss the hypetrains) but that was in 2015. I can't believe I thought the comic sans thing was so hilarious back then.

Recovered != retropropulsive landing. It will probably just land with parachutes:

Typically, the rockets themselves are built more like a plane: conveniently sized, specialized, pieces are bolted or welded together. However, placing the payload on top of the rocket and inside the fairing (or sometimes even connecting the stages) is called "integration." This is what the lower half of the Atlas V 5-meter fairing and centaur upper stage being vertically (rocket points up, as compared to horizontal) integrated looks like: However, frequently the payload is "encapsulated" in the fairing in a clean room, then integrated with the rest of the rocket, to prevent contamination. This is the vertical integration of the NROL-52 payload encapsulated in the Atlas V 4-meter fairing:
