NASA releases new details on next SLS rockets

NASA is fine-tuning its design for the new Space Launch System (SLS) that will send astronauts to the moon, asteroids and possibly Mars. Basically there will be three main types of rocket, the Block 1, Block 1A and Block 2. Block 1A and Block 2 will both have a crewed and a cargo variant, so that's a total of 5 models. The most important difference with what was announced last September is that the main core stage will now have four or five RS-25D/E Space Shuttle Main Engines (SSME) instead of three.

NASA's Next Manned Mission to an Asteroid

Now that the Space Launch System program is officially on its tracks, lets take a look at what NASA plans to do with the giant rocket. After the first couple of test flights (including a manned fly-by around the moon somewhere between 2017 and 2021), the first big objective is to send 4 astronauts to a 6 month trip to a Near Earth Object (NEO). The mission would be called 'Plymouth Rock'.

NASA Officially Announces the Space Launch System

Last Wednesday NASA officials publicly unveiled the Space Launch System, the new heavy lift rocket that will send astronauts beyond earth orbit, to asteroids, the moon and possibly some day to Mars. As I mentioned in an earlier post, the design has been known for a few months now, but for various political reasons, the project hadn't been officially announced yet.

The Saga of NASA's Heavy Lift Launcher

Last week, after years of studies and negotiations, NASA finally released a preliminary design for the new rocket that will replace the space shuttle. The new rocket will be a Shuttle-Derived Heavy Lift Vehicle, meaning that it will make maximum use of existing Space Shuttle components. Basically they will keep the Space Shuttle External tank and two Solid Rocket Boosters unchanged, remove the space shuttle, take the shuttle's three main engines and put them and the bottom of the External Tank, and put the cargo on top of the External Tank. This design is pretty much the solution proposed by the DIRECT team last year, called the Jupiter launch vehicle.
