SpaceX\u2019s Dragon spacecraft is continuing to make solid progress during the early years of its incremental roadmap, a path that has a firm focus on sending humans to Mars. With successful Commercial Cargo missions already under its belt, Dragon is already targeting the role of transporting NASA crews to the International Space Station (ISS).<\/p>\n<\/p>\n

Rise of the Dragon:<\/p>\n

Even before the three Shuttle orbiters had completed their final missions, NASA managers were already planning the handover of keys to Low Earth Orbit (LEO) to commercial companies, in turn allowing the Agency to refocus on Beyond Earth Orbit (BEO) exploration.<\/p>\n

SpaceX have already proven themselves to be the shining light of the commercial effort, fighting back from early issues with their initial launch vehicle, the Falcon 1, through to the successes that have resulted in three Dragon spacecraft berthing with the ISS.<\/p>\n

\"DragonThe next Dragon mission, the third under SpaceX\u2019s Commercial Ressuply Services (CRS) contract with NASA, will also aim to complete another milestone, as the CRS-3 (SpX-3) Dragon looks forward to a ride on the next version of the Falcon 9 launch vehicle.<\/p>\n

Falcon 9 v1.1 is at the center of two major milestones in SpaceX\u2019s future ambitions. The first involves the increased power of the new Merlin 1D engines, arranged in an \u201coctagonal\u201d pattern on a longer first stage.<\/p>\n

A single Second Stage Merlin VacD engine will be responsible for the final push to orbit. Also, 27 of these engines will power the three cores on the Falcon Heavy, set to debut next year.<\/p>\n

\"SpaceXFollowing the successful conclusion of development firings at SpaceX\u2019s Rocket Development and Test Facility in McGregor, Texas \u2013 the Merlin 1Ds are currently undergoing validation testing \u2013 with a test firing conducted on Thursday.<\/p>\n

Thanks to the new Falcon 9\u2019s increase in capability, SpaceX note future Dragon spacecraft \u2013 while always packed to the brim \u2013 riding with the upgraded Falcon will be able to carry a greater mass to the ISS, if NASA manifests denser cargo for Dragon, or heavy items for the trunk.<\/p>\n

\u201cDragon is volume-limited, meaning we always launch Dragon with its volume capacity filled,\u201d noted SpaceX spokesperson Christina Ra to NASASpaceFlight.com. \u201cThe original Falcon 9 was able to deliver 10,454 kg to LEO, while the upgraded Falcon 9 can deliver 13,150 kg.\u201d<\/p>\n

The future aim of the new Falcon 9 is more obvious when using the vehicle\u2019s other name, the Falcon 9-R \u2013 with \u201cR\u201d standing for \u201cReusable\u201d.<\/p>\n

Although the new Falcon 9 will be tasked with a number of satellite launches, ahead of launching the CRS-3 Dragon to the ISS, the rocket will eventually sprout legs.<\/p>\n

\"FalconRevealed to the public, via a speech to the National Press Club by SpaceX CEO and Founder Elon Musk in 2012, the aim is to create a fully-reusable launch system that results in both the First and Second Stages returning to Earth, allowing them to be refurbished for another launch.<\/p>\n

Testing has already begun, with the Grasshopper system currently testing hardware elements, propulsive landing and the landing legs structure, at the McGregor facility, with numerous incremental successes already achieved.<\/p>\n

The Dragon spacecraft has always been designed to return to Earth, providing NASA with much-needed downmass capability from the ISS.<\/p>\n

However, while every Dragon launched thus far has successfully returned home, the current method of parachute landing into the Pacific Ocean will eventually be replaced by propulsive landings on terra firma.<\/p>\n

\"HeadingWith future Dragon spacecraft sporting a series of eight SuperDraco liquid engines \u2013 built into the side walls of the capsule \u2013 these thrusters will provide an initial Launch Abort System (LAS) capability, by producing up to 120,000 pounds of axial thrust to drive the Dragon away from a failing launch vehicle.<\/p>\n

Because the system is integrated with the Dragon \u2013 as opposed to a Tower system that normally requires jettison shortly after first stage flight \u2013 the spacecraft can technically abort within much longer periods.<\/p>\n

However, the big advantage \u2013 per SpaceX\u2019s ambitions \u2013 is the use of the engines during the end portion of the mission, allowing Dragon to land propulsively. Once this capability is online, in tandem with the return of the First and Second stages, SpaceX will be in the position of returning all of the launch system hardware to the ground for reuse.<\/p>\n

\"DragonPropulsive landing of the Dragon will be one of the key technologies used when SpaceX begin to fly crews on the spacecraft. However, the timing of the switch from water to ground landings will be negotiated between SpaceX and NASA.<\/p>\n

\u201cAs we\u2019ve noted in the past, future iterations of Dragon will have the ability to propulsively land. SpaceX certainly sees value in implementing a propulsive landing system prior to crew launches but timing for implementation will be something we discuss with NASA as they are the primary customer for both types of flights,\u201d added Ms. Ra.<\/p>\n

As part of their drive to fly humans on the Dragon, SpaceX are continuing to work through the milestones of their Commercial Crew Integrated Capability (CCiCap) contract with NASA.<\/p>\n

\"CrewedThe company recently completed the fifth and sixth milestones for SpaceX, and remain on target to complete all 14 of its CCiCap milestones by mid-2014.<\/p>\n

The latest milestones involved the presentation of SpaceX\u2019s human certification plan, outlining testing, demonstrations, analyses, inspections, verifications and training events. This was followed by a review of the upcoming pad abort test, which is currently targeted for later this year or early next year from Cape Canaveral Air Force Station\u2019s Space Launch Complex 40 in Florida.<\/p>\n

\u201cThe beauty of having the pad abort test review was it allowed both NASA and SpaceX to start coalescing toward an understanding of what will be tested and how we\u2019ll measure success,\u201d noted Ed Mango, NASA\u2019s CCP manager. \u201cWe\u2019re really looking forward to seeing SpaceX\u2019s pad abort system take off from along Florida\u2019s Space Coast.\u201d<\/p>\n
