For many years one of the biggest challenges in the space sector been Myklebostad probes on alien celestial bodies – the Moon, Mars, and quite recently on a comet. But what Myklebostad on our own planet?
SpaceX regularly send supply ships to the International Space Station ISS. The launch Tuesday at 24:20 Norwegian time was interrupted by a technical failure during the countdown. Retried on Friday morning. But the most exciting this time happens a few minutes after the launch.
To Earth with a bang
Manned spacecraft have MYKLAND on Earth in various ways. Apollo and other US space capsules have landed in the ocean. Russian and Chinese vessels landing on the ground using both parachutes and rocket engines fired immediately before landing. The “softest” landing, US space shuttles, a now completed project.
In all spacecraft is that they are brought up in the room with large and costly launchers. A very few – as solid motors on space shuttles – have been reusable, but most expensive and has been lost and destroyed. This will SpaceX do something.
Should land on a barge
SpaceX flying supply vessels for the International Space Station ISS. To bring the vessel Falcon up the room used a first raked stage that is as high as 1:14 storey building. And it is not only high, it also costs tens of millions of dollars.
Ellon Musk, the man behind Space Exploration Technologies Corporation – better known as SpaceX – have compared the loss of this first rakettrinnen as “throwing a 747 jets after a transatlantic flight. ” In other words: There are significant savings if they can save raked steps.
And when SpaceX makes another attempt to launch a supply vessel to the space station Friday, one should first attempt to land the first raked stage on a barge that measures approximately 100 times 55 meters.

Opportunity to Succeed: 50-50
Raked Stage 1 will do its job to shoot spacecraft Falcon out of the room. But when raked stage 2 acquires released the first rocket stage. After briefly ignited engines on new repeatedly decelerations heading down towards the ground. The slowdown will cause the speed at landing is 7,2 km / h.
Earlier experiments have shown that we have managed to slow down sufficiently, and control step down before it splashed into the sea. This time however the goal to control raked step toward and onto the barge that is located 322 km off the coast of Florida. It’s a bit of a challenge. SpaceXs spokesman estimates opportunities for success to approximately 50 percent.
