With the 90 day report being a huge roundabout, inefficient way to reach Mars and the Mars Reference Design Mission, following the late-NASA tradition of "not the cheapest possible", SpaceX CEO Elon Musk wants to go to Mars, and build a permanent colony there. The ultimate objective: Make going...

I'm really surprised I haven't seen this yet... So Shuttle Fleet has a lot of very awesome features for the space shuttle, off the to of my head: 1. New, much more realistic SFX 2. Much better simulation of engine sounds 3. Abort and other calls to/from houston and the Shuttle. 4. GPC MFD -...

Whenever I try to enter ITEM 22 to start the countdown timer for the CRT to fire the OMS, the sim crashes. Orbiter.log said that an old function had been called on that no longer existed. So really, where can I get an updated version of Space Shuttle Ultra? It seems like it shouldn't be that...

Hello, Normally I'm working on one project or another to pass time, in this case, I've ran into a fairly interesting idea... So the Venture Star was a huge promise and a dream that ultimately failed. There are probably some folks around here that have more information on it than I do (which...

Hey, For a long time I've been wanting to be able to work calculations by hand for all the maneuvers conducted in orbiter, for it's own sake, but mostly to design realistic vehicles for Orbiter. I'm just getting into Calculus as a senior in high school, so lots of things are starting to open up...

This is a concept I've been on for maybe half a year now, it's a shuttle that works for all the Galilean moons, and with some simple field mods (reflective foil for sun protection, like the foil used on the Apollo landers) also works on Luna. An "Exo-Atmospheric Orbital Transportation Vehicle"...

So, I'm being a bit rash to post this so quickly after I came up with the idea, but It's really neat... The idea is to replace the 3 SSME's with Nuclear Thermal Rockets. The objective is that this new nuclear shuttle should be able to either go to the Moon or Mars. To facilitate the lower...

Okay, one thing I've never seen addressed is the process of creating a new infrastructure on an exo-solar planet. There's a huge amount of discussion on interstellar drive systems, tech, FTL, etc. etc, but I've never actually seen any ideas or proposals on how to create a whole new civilization...

There's a number of engineering concepts I'm going over for some science fiction and want to discuss a little. First is the Fusion Steam Engine. Essentially, it's Magnetically Confined Fusion. (I think I'll run with D-T fusion, since mission times are in days/weeks) It's for the engines on a an...

Here's a neat idea I came up with, I can't wait to see how it doesn't work :P Inspired by the fusion Bussard Ramjet concept... Here's a blueprint. A: Positively-charged parabolic structure. B: Negatively-charged parabolic structure. C: Positively-charged "tunnel". D: Slightly negatively charged...

If I understand correctly, I think the big advantage of an SSTO would be it's short turnaround time because no processing / attaching a second stage, etc. etc. But what if both stages had a "spaceplane" design? Stage 1 "Mothership": #1. Uses JP-1-fuelled turbofans to climb to their service...
