However, along with its first flight with the Dragon spacecraft as its passenger, this next Falcon 9 v1.1 will also be sporting landing legs, allowing for the next milestone in testing towards the rocket becoming fully reusable.<\/p>\n
The debut of the Falcon 9 v1.1 \u2013 carrying the CASSIOPE satellite \u2013 involved the first \u201cboost back\u201d test of the first stage, while sources note there was also a boost back test during the SES-8 mission, or at least the restart of the first stage post staging.<\/p>\n
It has not yet confirmed how much testing was involved on the most recent F9 v1.1 mission, which successfully lofted the Thaicom-6 satellite.<\/p>\n

According to a speech by Tom Mueller, Co-Founder and VP Propulsion for SpaceX \u2013 at the \u201cExploring the Next Frontier: The Commercialization of Space is Lifting Off\u201d event in Santa Barbara, California, on Wednesday night \u2013 the F9 first stage involved in the CASSIOPE launch crashed into the water during the return test.<\/p>\n(adsbygoogle = window.adsbygoogle || []).push({});<\/p>\n
The problem related to the stage spinning during its return, causing the fuel to centrifuge.<\/p>\n
According to Mr. Mueller, the baffles in the tanks were not designed for those stresses, causing debris to get into the engines, resulting in them shutting down prematurely.<\/p>\n

It has been long-rumored that the Falcon 9 involved with the CRS-3 mission may involve legs being added to its aft. SpaceX officials have so far been unable to answer questions, sent by NASASpaceFlight.com last month, specific to their reusability efforts.<\/p>\nHowever, thanks to questions put to Mr. Mueller by a NASASpaceflight.com L2 member in attendance at the Central Coast MIT Enterprise Forum event, the SpaceX Co-Founder \u2013 who provided permission for his comments to be reported \u2013 confirmed legs have been installed on the CRS-3 Falcon 9 v1.1.<\/p>\n
Mr. Mueller noted the aim is to conduct a soft landing \u2013 or soft touchdown \u2013 on water, after the first stage boosts back from its role in aiding Dragon\u2019s ascent uphill.<\/p>\n

The first images of the landing legs were revealed via photos taken by local residents \u2013 some of which were provided to L2 (along with newly added video) \u2013 at SpaceX\u2019s McGregor test facility in Texas last month, with the structures attached to the Grasshopper 2 test vehicle.<\/p>\nGrasshopper 2 is currently being put through its paces with static firings, ahead of what is understood to be one test flight in Texas, prior to the vehicle being shipped to Spaceport America in New Mexico, where it will be able to reach higher altitudes.<\/p>\n
For the CRS-3 Falcon 9, the legs will be stowed on the aft of the first stage during the ride uphill, prior to \u2013 at least by design \u2013 deploying via pneumatic cylinders driven by compressed helium once the stage is on the final part of its powered descent.<\/p>\n

SpaceX Chief Designer and CEO Elon Musk had already noted the design is a nested, telescoping piston using high pressure helium, given the requirement the system needs to be ultra light.<\/p>\nIt is unclear how many milestones the CRS-3 Falcon 9 will undertake, with Mr. Mueller adding their upcoming development program includes a test launch that will aim to go suborbital, prior to collect re-entry data.<\/p>\n
Mr. Mueller also provided additional details on SpaceX\u2019s plans for a launch vehicle that is aimed to enable missions to Mars, specifically noting their current developmental progress with the Raptor engine.<\/p>\n
That information is currently being evaluated for the purpose of a future article.<\/p>\n
