So finally they pulled it through, SpaceX launched a rocket, it went to space, delivered its payload(which was 11 satellites), came back and then it landed, making history. The last time they tried it, it was in April but it exploded. So they made a few changes and tried it again only to taste success. It deployed 11 satellites into the target orbit before coming back to land successfully.
Elon Musk’s SpaceX has been trying to make the cost space missions and satellite launches considerably low. The major part in increasing any space mission’s cost was how a complete rocket has to be built for each and every launch missions. All rockets which travel into the orbit are either destroyed or lost after delivering its payload. So if SpaceX is able to continuously use the reusable rockets, this will bring down the cost of entire space missions.
Anyway although SpaceX has been trying to achieve this for the past one year, another company beat them to it by last November. Jeff Bezo’s private spaceflight company Blue origin had landed their rocket New Shepard post launch. But their version was considerably slower and doesn’t go into deep space unlike Falcon 9.
Here the video which shows the landing of Falcon 9.
And the path: There and back again.
According to Elon Musk, it costs $16 million to manufacture Falcon 9 and it needs $200,000 worth of fuel. So if they are able to routinely reuse rockets, it would change the whole space industry as its eliminating a major part of the costs associated with the launch, in this case its $16 million. Now needless to say, it will force other space agencies to explore reusable rockets to compete with SpaceX if they want future contracts.
