See also Small Solar System body. So the reason I'm asking this is because, essentially, there are a lot of SSSBs all over the place. Obviously. <:I Some of you might also be aware of various mission concepts I have discussed on other threads. For a couple of months now, I've been working on...

So a while back I decided that the storyline for my fiction space agency (IPSA) was lacking some unmanned planetary science missions, so I started thinking up proposals. One of those resulted in VESPA (currently the Venus Environmental Surveyor Preliminary Assessment), an ambitious mission...

The Aquarius B1 is a two-staged launch vehicle designed to launch between 50-130 mT (metric tons/tonnes) to LEO, depending on the configuration used. This puts it squarely in the heavy/super-heavy class of launch vehicles. It is also the commercial and institutional workhorse of my fictional...

Was mulling over whether or not to make this thread, considering how previous ones went. As you can see, I have made the (possibly?) regrettable mistake of making a thread. Not on a rocket question, but a mission concept for sample return! From a asteroid and/or comet, no less, given the recent...

As in, calculating the dry mass of a 5m rocket stage, like Atlas V Phase 2. Previously, a technique for finding out the dry mass of the stage was to make my dry mass:fuel mass ratios similar to that of actual rocket stages. However, I noticed two potential problems with this: - to get a...

Facebook Twitter RocketHub Google + Space College Also known as the International Cometary Explorer (ICE) spacecraft, the International Sun/Earth Explorer 3 (ISEE-3) satellite, was launched August 12, 1978, by a Delta 2914. It was actually just one of three spacecraft ( there was a ISEE-1 and...

SpaceX planning propulsive Dragon landing tests... A equivalent NSF thread...

As we all have been hoping for, Space Exploration Technologies Corporation (SpaceX) of Hawthorne, California have posted two videos of the landing attempt of the SpaceX CRS-3 F9 v1.1 first stage on April 18 2014. Unfortunately, it's kind of degraded... Having spent quite a lot of time...

I've been calculating realistic data for a few rocket concepts I've been working for a while now. Only recently, a problem popped up… Out of the total volume that a typical rocket tank has, how much of it actually has usable fuel in it? How much is "ullage gas"? How much of that propellant is...

(Might work on this in the future...) In my fictional space program, the titular agency operates a man-made island as a launch site, known as tentatively as Ominke Atoll. Basically, I'm looking for a set of parameters for this island's proposed location. They are: 1) A location allowing for...

This article got me thinking... How profitable, and how feasible is it to construct "critical" rocket components from composite materials? Such components being payload fairings, interstages, or as the article focuses on, propellant tanks. Any application such components would/could be used...

My first thread... Planning on making a HLV addon (in the long term) to go with a fictional space program. I've actually already designed a model with the dimensions of said HLV, though I'm having some problems calculating the fuel and oxidizer tank lengths. The aforementioned HLV uses a...
