At 6:20 am EST on Tuesday morning, Space Exploration Technologies (SpaceX) will launch its 5th payload resupply mission to the International Space Station in a coordinated effort with NASA.

Though, not at all like the past 4 missions, SpaceX will be doing something strange with the primary part of its Falcon 9 rocket: after its job is done, the organization will attempt to land the rocket vertically on a platform hovering in the Atlantic Ocean a couple of minutes later.

This would be an exceptional deed, and the organization says it just has a 50% possibility of victory. If it meets expectations, however, SpaceX could reuse the rocket on a future flight — part of a more extensive push towards reusability that could significantly drive down the expense of space travel.

What SpaceX is attempting to do

The organization will launch a Falcon 9 rocket from Cape Canaveral, Florida, so as to convey an uncrewed space capsule up to the International Space Station. The capsule will bring various types of freight to the ISS: food, life support supplies, and a few exploratory trials.

The rocket itself is comprised of two sections: a 138-foot-tall first stage, which burns for the initial couple of minutes of flight, lifting the rocket up to an elevation of around 50 miles before unraveling and falling back to Earth, and a smaller, 49-foot-tall second stage, which burns for an additional five minutes or thereabouts, shipping the shuttle into orbit before detaching and falling back down to earth too.

Typically, both of these stages — and the stages that make up other rockets on the whole — fall apart into pieces as they dive descending, ultimately plummeting in the sea and getting to be unusable. Yet on Tuesday, as the first stage falls back to earth, SpaceX will shoot its engine so as to settle and direct it for a controlled landing.

SpaceX made comparative endeavors to land its rockets as a major aspect of three past launches, and two times, it figured out how to get the rocket to gradually float and land upright in the sea, however then it fell over.

This time, its utilizing an independent uncrewed freight boat, positioned around 200 miles east of Jacksonville, Florida, as a landing stage.

As the rocket dives, steerable blades joined to its outside will help guide it and ease it off. As it nears the canal boat, a set of legs will unfold from the base of the rocket, and if all goes well, it’ll decelerate to a speed of around 4.5 miles/hour before softly landing on them, completely upright.

This is an exceptionally troublesome move for a couple of diverse reasons. For one, the rocket is essentially designed to launch a shuttle into space — which implies that it’ll be dubious to slow down and guide on the route down.

Furthermore, with its legs amplified, the rocket will be 70 feet wide, so landing it on the 300-foot wide hovering stage will oblige a high level of exactness. Lastly, the stage itself will be a moving target as it influences somewhat in the water.

SpaceX has contrasted this with “attempting to adjust an elastic broomstick on your hand amidst a wind storm,” and has made it clear that the endeavor may not work. However, if it does, the deed could be a transformative one for the fate of space travel.

Why SpaceX wants to reuse a rocket

One of the aspects that make space travel so lavish is the fact that a large portion of the supplies used to put payload or individuals in orbit is annihilated after each use. SpacexX CEO Elon Musk has notably compared this to discarding a new 747 after a sole flight to London.

From the earliest starting point, his organization has required to make spaceflight possible with reusable segments. Yet though that’s a tremendously ruthless ambition, if SpaceX can draw off this landing, it’ll be a first move towards attaining it.

The rocket’s external surfaces are intended to oppose erosion from seawater, and at first, SpaceX attempted to utilize parachutes to decelerate the stages as they go down. Though, they broke apart because of the pressure and heat created amid the plummet, so the organization moved to the present, powered landing approach in 2011.

If this first stage is effectively landed, it could be renovated and utilized for a future flight. The Dragon capsule it launches into orbit, meanwhile, is by now reusable, and the organization has intends to inevitably try landing and reusing the second rocket platform in a comparative manner too. If effective, this would imply that most of the Falcon 9’s gears could be utilized a few times.

This would diminish the expense of spaceflight in an immense manner. As of now, building another Falcon 9 rocket costs $54 million, however utilizing it to put a payload into space costs just about $200,000 worth of fuel. Making sense of an approach to reuse the rocket could make different varieties of missions — commercial satellite launches, joint efforts with NASA, and space tourism — less expensive by orders of scale, opening up various new potentials in spaceflight.
