Reusable Launch & Space Transport Information
Part 1 - General Info, US Projects, X Prize


Flight test on Nov. 13, 2006 of the Blue Origin Goddard prototype space vehicle.

A fully reusable launch system is the key to providing the low cost access to Space. Low cost access is in turn the key to extensive human exploration and large scale settlement of the solar system.

The Space Shuttle succeeded technically as a partially reusable launcher but failed miserably economically. It requires several thousand support personal and 2 months or more to rebuild a Shuttle for its next launch. Shuttle launch costs are roughly $20,000/kg, which is actually higher than most expendable launchers.

During the 1990s a number of RLV (Reusable Launch Vehicle) startup companies appeared due to the promise of a lucrative market for launching spacecraft for the low earth orbit communications constellations that were then in development. Unfortunately, the failures of Iridium, Globalstar, and the other constellations pulled the rug out from under these space transport companes and several disappeared or went into long-term limbo.

The failures of several NASA projects, such as the X-33 and X-34, also discouraged government investment in RLV technology. Bad design and poor management had more to do with these failure than technical challenges but they nevertheless convinced many in NASA and elsewhere that RLV technology was not at hand.

Currently (circa 2008), the most intense RLV development activity is taking place in the suborbital spaceflight area. These vehicles are primarily intended for space tourism but will also take over many of the scientific applications carried out by sounding rockets.

SpaceX hopes to proved that its Falcon rockets can be at least partially reusable. The first stage for the Falcon I and both stages of the Falcon 9 are designed to parachute into the ocean for recovery and reuse.

The resources about such RLV projects & technology present, past and future. The T sign indicates that a project has an entry in the RLV Table.

Also, included are in-space vehicles, which can be launched in different ways. For example, such a vehicle might be released in space from a shuttle or launched on top of an expendable. They might operate in space indefinitely or, in other cases, return to earth to be used again for crew transport.

See the New Launch Technologies section for resources related to new conventional expendable and partially reusable rocket vehicles. It also offers information and links dealing with non-rocket types of transport such as space elevators and laser launchers. See the Hypersonic Transport sections for resources related to scramjet vehicles.

Note: Many people complain that the term reusable launch vehicle is clumsy and archaic. We don't, after all, call airliners reusable takeoff vehicles! The RLV term helps to perpetuate the myth that every flight of a rocket powered vehicle is a lucky shot and that such craft will never attain the high reliability and lost cost operations of airliners.

However, in the next few years we will see robust and reliable rocket powered suborbital vehicles begin making daily flights, even multiple flights in a day. It will then seem rather silly to talk about countdowns and launches. They will simply takeoff when they are ready, just like any other flying vehicle.

There is not been put forward a generally accepted substitute term. The SpaceShipOne success argues for spaceship but it still isn't generally accepted. I'm gradually replacing the RLV terminology here with space transport. However, some other term, such as spaceliner, rocketship, etc , may eventually become the more popular choice.

See the RLV & Space Transport News section for the latest on the development of RLV and other space transportation technologies.

Suborbital RLV Projects
These companies/projects focus on sub-orbital launchers for commercial markets. Some of the teams participated in the X PRIZE, which was was won by the Scaled Composites SpaceShipOne. We indicate here which of the projects were also X-PRIZE participants.

This list includes some non-US projects. Other non-US suborbital projects are listed in RLV Part 2. SThe Table compae some of the sub-orbital vehicles in development. News and resources about some of the suborbital companies can be found at Suborbital Vehicle Companies - Commercial Space Wiki.
