However, as with all \u201cVisiting Vehicles\u201d, even approaching the ISS requires numerous safety requirements to be passed, procedures which protect the $100 billion Station from undesirable incidents which could threaten both the ISS and it\u2019s crew.<\/p>\n
Highlighted as the main item of interest currently being worked by both NASA and SpaceX, engineers are evaluating a \u201cconcern\u201d relating to \u201cSecondary Payloads\u201d riding with the Falcon 9 into orbit.<\/p>\n
Ranging back to an an agreement to launch 18 ORBCOMM Generation 2 (OG2) satellites as early as the fourth quarter of 2010 through 2014, the delivery of the second-generation satellites into Low Earth Orbit (LEO) was set to be carried out on the Falcon 1e launch vehicle.<\/p>\n

The Falcon 1e sports upgraded propulsion, structures and avionics systems when compared to the Falcon 1 \u2013 in order to further improve reliability and mass-to-orbit capability.<\/p>\nRocket building kits

However, SpaceX \u2013 working to further maximize the cost-effectiveness of their COTS\/CRS missions \u2013 decided to included the additional payloads as passengers on the Falcon 9\u2019s second stage, allowing them to be deployed after the Dragon separates from the Falcon 9.<\/p>\n
It is currently understood that two ORBCOMM satellites will ride uphill with Falcon 9 during the C2\/C3 flight, which caused ISS managers some interest from the standpoint of a potential collision risk with the ISS. As such, NASA are using their experienced Monte Carlo analysis methods to clear this concern.<\/p>\n
\u201cSpaceX Second Stage Payloads Collision Risk: NASA is now receiving necessary data for orbital plane impacts, but it is still uncertain how the analysis will fallout,\u201d noted one MOD ISS presentation from August 10 (available on L2). \u201cGeneric policy has not yet been developed.\u201d<\/p>\n
SpaceX also acknowledged this ongoing work, citing they were working with NASA to resolve the potential risks associated with the secondary payloads.<\/p>\n

\u201cOver the last several months, SpaceX has been hard at work preparing for our next flight \u2013 a mission designed to demonstrate that a privately-developed space transportation system can deliver cargo to and from the International Space Station (ISS). NASA has given us a Nov. 30, 2011 launch date, which should be followed nine days later by Dragon berthing at the ISS,\u201d noted SpaceX.
\n
\n\u201cNASA has agreed in principle to allow SpaceX to combine all of the tests and demonstration activities that we originally proposed as two separate missions (COTS Demo 2 and COTS Demo 3) into a single mission. Furthermore, SpaceX plans to carry additional payloads aboard the Falcon 9\u2019s second stage which will deploy after Dragon separates and is well on its way to the ISS.<\/p>\n\u201cNASA will grant formal approval for the combined COTS missions pending resolution of any potential risks associated with these secondary payloads. Our team continues to work closely with NASA to resolve all questions and concerns.\u201d<\/p>\n
With safety reviews a standard for NASA, the procedures are already being lined up through their respective phases, with phase 3 expected to be completed early next year \u2013 likely relating to a green light for the opening CRS flight for the Dragon in 2012.<\/p>\n

\u201cSpaceX\/Dragon: Phase 3 part 1 safety review tentatively scheduled for end of September 2011. Starting to see easy phase 3 level hazard reports,\u201d added the MOD ISS Presentation. \u201cSome phase 2 level work pushed off to phase 3 (not unusual). Estimate phase 3 complete 2\/2012.\u201d<\/p>\n

Known also as Falcon 9\u2019s Flight 4, the CRS-1 flight hardware is already well into production, an in-house process which is undergoing a ramp up in the fabrication of the Falcon 9s \u2013 three of which will be required for the 2013 debut of the Falcon Heavy at USAF Vandenberg in California.<\/p>\n\u201cSignificant additional tooling and automation will be added to the factory, as we build towards the capability of producing a Falcon 9 first stage or Falcon Heavy side booster every week and an upper stage every two weeks. Depending on demand, Dragon production is planned for a rate of one every six to eight weeks.<\/p>\n
As SpaceX rightly note, the arrival of the C2\/C3 Dragon at the ISS this year \u2013 as much as the mission may slip into 2012 due to a tight schedule from the ISS side, per sources \u2013 will be a key milestone for commercial space flight, as the cargo Dragon docks and is ingressed by the crew of the ISS, marking a historic first.<\/p>\n
\u201cThis next mission represents a huge milestone not only for SpaceX, but also for NASA and the US space program. When the astronauts stationed on the ISS open the hatch and enter the Dragon spacecraft for the first time, it will mark the beginning of a new era in space travel,\u201d noted SpaceX.<\/p>\n
The most recent milestone for this potential combination demo mission was carried out at SLC-40 at Cape Canaveral in Florida, with a successful Wet Dress Rehearsal (WDR) carried out on the Falcon 9 Flight 3 vehicle.<\/p>\n
