Meet NASA’s business area capsule contenders
Positive, the Dragon V2 is the newest (and biggest) spacecraft from SpaceX, nevertheless it’s not the one capsule which will in the future schlep astronauts to the Worldwide Area Station. In truth, Elon Musk’s agency is only one of three personal outfits at present competing in a NASA program for business launches with their very own automobiles. We have surveyed the area capsule panorama and have whipped up a primer on the longer term crafts which will wind up taking people to area.
The second-gen Dragon simply had its coming-out social gathering, however we’ll recap the highlights. As SpaceX’s workhorse, the unique Dragon has sat atop Falcon 9 rockets and carried cargo to the Worldwide Area Station, however it hasn’t been capable of safely transport people. Dragon V2 cures that, offering lodging for as much as seven passengers (or much less for extra cargo area). What’s extra, it is anticipated the capsule can be utilized as much as 10 occasions earlier than needing vital repairs.
Eight new SuperDraco engines are fitted into the car, permitting it to land on strong floor with the precision of helicopter, all with out utilizing a single parachute. In fact, in an emergency, the vessel can use its reserve chutes and drop itself into the ocean. A battery of checks continues to be within the playing cards for Dragon V2 earlier than it goes airborne, nevertheless it’s anticipated to fly with people aboard in 2016.

Boeing’s entry into the business crew and cargo program is the Crew Area Transportation-one hundred, or CST-one hundred for brief. Along with shuttling astronauts to the Worldwide Area Station, it is meant to hold people to personal area stations like these proposed by Bigelow Aerospace. When it is tasked with taxiing people, Boeing’s vessel can carry a crew as giant as seven.
For landings, the craft slows itself down with parachutes and touches down on terra firma. Within the case of an emergency, nevertheless, the car can take a dip within the sea.
The CST-one hundred is not fairly able to be tossed into the vacuum of area fairly but, however it’s making good progress. In February, the hardware that connects it to Atlas V rockets handed muster with NASA, and it is on monitor to hit the event milestones the area company is in search of in 2014.

The odd duck within the authorities’s business crew program is the Dream Chaser. Relatively than depend on a capsule design, Sierra Nevada Company’s constructed its astronaut taxi by choosing up the area shuttle’s mantle. Though it resembles NASA’s retired 184-foot lengthy workhorse, it measures up at simply 29.5 ft lengthy. Not solely does it appear to be a pint-sized shuttle, however it additionally features very similar to one.
The Dream Chaser makes use of a completely totally different type of managed descent from its competitors. By gliding down from low-Earth orbit, the contraption is ready to land at any airport runway fitted to business airliners. Whereas it builds on the shuttle’s strengths, it additionally inherits a few of its weaknesses. Sierra Nevada’s answer can deal with ferrying as much as seven people to area in low-earth orbit, however it’s not match for lengthy journeys to different planets.
In November of 2016, the pint-sized shuttle lookalike is scheduled to make it to orbit for the primary time. As if the similarities to NASA’s spaceplane weren’t sufficient already, it is set to make use of the exact same runway (for touchdown) as its a lot bigger doppelgänger.

OK, NASA’s subsequent-era area car, Orion, is not a business craft, nevertheless it’s definitely value mentioning. Though it was initially devised as a part of the now-canceled Constellation program that aimed to take astronauts to asteroids, Mars and the moon, the area company’s constructing a model of the craft — with the assistance of Lockheed Martin — that’ll grow to be its Swiss Military knife. Now dubbed the Orion Multi-Objective Crew Car (MPCV), it’s going to have the ability to make those self same journeys utilizing a brand new rocket setup referred to as the Area Launch System. What’s extra, it’s going to additionally have the ability to haul as much as six individuals to the Worldwide Area Station if the necessity arises.
Returning to Earth for Orion means deploying parachutes and splashing down within the ocean, very similar to the Apollo missions did. In an emergency, nevertheless, the vessel can safely set itself down on soil.
A little bit of legwork continues to be wanted earlier than Orion could make its method into orbit, however its first check flight is not far off. Come December 2014, it’s going to head three,600 miles away from our blue marble and land — if all goes nicely — in a single piece.
Although every of those business automobiles is progressing steadily, it will not be till 2016 that any of them are slung into orbit. Sarcastically, for as a lot as NASA’s demise is proclaimed, it’s going to launch Orion earlier than the CST-one hundred and Dream Chaser even get their first style of area’s vacuum. Regardless of which firm (or corporations) NASA finally faucets for future crew and cargo missions, area aficionados could have the personal area race as leisure.
