In three weeks, Spacex could demonstrate the first reusable rocket booster and pave the way to radically cheaper spaceflight

After sending cargo towards the International Space Station, the first stage of the Falcon 9 rocket will return nearly immediately after liftoff and return and fire its engines for the second time. 

 

The burn will allow the rocket to reenter the atmosphere in controlled flight, without breaking up and disintegrating on the way down as most booster rockets do. The launch was delayed to March 30th.

 
The machine will settle over the Atlantic Ocean off the coast of its Cape Canaveral launchpad, engines roaring, and four landing legs will unfold from the rocket’s sides. Hovering over ocean, the rocket will kick up a salt spray along with the flames and smoke. Finally, the engines will cut off and the rocket will drop the last few feet into the ocean for recovery by a waiting barge.
 
Future flights of the so-called F9R rocket will have it touching down on land. For now, a water landing ensures maximum safety in case the rocket goes off course.
 
After recovering the rocket from the water on Sunday, SpaceX engineers and technicians will study it to determine what it would take to refurbish such a rocket for reuse. SpaceX also has plans to recover and reuse the second stage rocket, but for now, it will recover only the first stage and its nine Merlin engines, which make up the bulk of the cost of the rocket.
 
Even without reusable rockets, SpaceX has already shaken up the $190-billion-a-year satellite launch market with radically lower launch costs than its competitors. The company advertises $55.6 million per Falcon 9 launch.
 
Its competitors are less forthcoming about how much they charge, but French rocket company Arianespace has indicated that it may ask for an increase in government subsidies to remain competitive with SpaceX.

Reusable fuel from Space X has been anticipated for some time as a "new trick" that would make a big difference in space explorations - we will soon see this in action ! Exciting Reply

Elon Musk is trying to revive space explorations with new ideas and concepts. Recently he told Congress: Space would be cheaper if the gov’t supported competition - no doubt, SpaceX is ready compete

Yes, Elon Musk testified before the U.S. Senate with harsh words about the artificially inflated cost of launching spacecraft. He is trying to remove such artificial obstacles - good move Reply

Elon Musk is very confident about his SpaceX capabilities and he sated: "We are unilaterally restoring America’s competitiveness in the global commercial space launch market as the only US company consistently winning head-to-head competitions for launch opportunities at the world-class level." A big claim! Reply
