After several blog posts describing spaceplanes (like the sleek experimental British Skylon plane), it is time to write about one of the alternative proposals for reusable space-capable craft which are capable of both take-off and landing. In the old spaceman fantasies from the golden age of science fiction, human explorers flew their rockets to another world, dropped through the atmosphere and landed vertically. Their rocket set around while the astronauts had fantastical adventures. Then they rushed back aboard and blasted off!
The Grasshopper at a SpaceX facility in Texas
Last week (March 7th, 2013) an experimental rocket named Grasshopper flew a record 80 meters (263 feet) before landing perfectly on the launch pad where it started. Grasshopper was built by Space Exploration Technologies or SpaceX, the private space transport company founded by PayPal billionaire, Elon Musk (who–based on his name and his legacy–may be a James Bond villain or an alien philanthropist). SpaceX is the first privately funded company to successfully launch a spacecraft into orbit and recover it and the budding company has also been first past numerous other milestones in the commercialization of space. Instead of giving everything Roman names like NASA, SpaceX gives its crafts and components Arthurian names such as Merlin, Kestrel, and Draco (I’m going to pretend there was a grasshopper at least somewhere in T. H. White).
The grasshopper blasts off–or maybe lands?
The reusable first stage tests of Grasshopper are breaking new ground in the fields of guidance and stability (which are required to land a Grasshopper). If all continues to go well the company plans on supersonic tests later this year. As these become more glorious and more dangerous it is unclear if they will seek to have their current Texas facility made into an official spaceport or if they will move out to the blazing glory of White Sands with the Airforce, NASA, and Virgin Galactic. Whatever the case I salute them for flying a smokestack around the countryside and then landing it on a basketball court. Perhaps I was too hasty to dismiss the possibilities of commercial spaceflight!
