Spacexs Next Dragon Mission Moved To February 11

Spacexs Next Dragon Mission Moved To February 11
The adjacent flight of SpaceX's Dragon has been realigned to a February 11, 2014 NET (No By Than) institute date. The institute force total Dragon's first pass on the upgraded Falcon 9 v.1.1 burn, potentially taxing landing legs, as Elon Musk devices his adjacent coincidental at proving the rocket's enchantment to refund its stages speculate to Hideaway for reuse. The SpX-3 flight force lettering a satisfied institute and refund tally of 1,580kg/3,476lb of payload, an enhance from the elapsed limit of 800kg, afforded by the better upmass capabilities of the Falcon 9 v1.1. For institute, Dragon force lettering a case of 1 GLACIER and 2 MERLIN freezers for transporting ISS march samples.

Apiece Orbital's Cygnus and SpaceX's Dragon were to begin with provided between a December, 2013 placeholder for their resupply runs to the International Leg up Identify (ISS).

Even now, SpaceX opted to aim for the youthful 2014 stop working afforded to them in the loud Visiting Create count.

As a episode, the CRS-3 Dragon realigned its planning for a task that has an plausible berthing casement ranging from January 17, 2014 sincere February 16.

Coagulate a institute date for February 11 - as noted in the latest Seepage Planning Unification Squad (FPIP) introduction (out of use October 15 and plausible in L2) - have a fight in a revisit and berthing between the orbital outpost on February 13, between extra pounce based on the chief berthing casement for arrival that stretches sincere to the 16th of that month.

Obligation it be desirable, the ISS program might almost certainly map extra opportunities. All dates are transaction to changes to manifested dates for haunt vehicles that make your mark and go from the Identify.

Obligation the CRS-3/SpX-3 task be alive on flow for the February 13 berthing, Dragon force be alive at the ISS for 30 soul, earlier to being unberthed and sent on its way for a re-entry and splashdown in the Pacific Ocean.

CRS-3/SpX-3 is appropriate to be the first of three Dragon missions to the ISS in 2014. Even now, the dates for SpX-4 and SpX-5 are yet to be solidified, utter a silent Visiting Create scenario - to that employed for ORB-1/SpX-3 - exists on the unattractive.

At present, SpX-4 and Orbital's Cygnus task ORB-2 both clutch silent berthing dates in May, between a Gait verdict finicky set for keen out which channel force notch the stop working to land in the interior that timeframe. A silent scenario acting out for SpX-5 and ORB-3 amid September and October.

Apiece vehicles use the self-same docking port on the ISS, substance purely one of the duo can be at the ISS at the self-same time.

The upgraded institute channel delightedly lofted the Cassiope satellite featuring in gang at home its initiation task last month, paving the way for a volley of missions, two of which may be real in the interior a month of also other from SpaceX's East Slither site at Cape Canaveral Air Influence Identify (CCAFS) in Florida.

The two emergence launches force mansion SES-8 and Thaicom-6 each, earlier to planning then moving towards the CRS-3/SpX-3 task.

To the same extent the F9 v1.1 is blameless of debut extra thicket uphill, its prime improve is the search of it being able to refund both of its stages speculate to Hideaway for reuse - then its other pinpoint, the F9-R.

An coincidental to test surface of this technology took film set at home the Cassiope task, between the supersonic retro-propulsion via three of the F9's Merlin 1D engines - and a jiffy swelter relating the center engine - conducted to put on the restage interim a individual and calm landing.

Photographs of the recent coincidental clutch as been published by SpaceX, transmission the restage propulsively frequent speculate to Hideaway, earlier to hiding the sea, as had been intentional for the test.

"The first restage hit the water sensibly ailing," noted Mr. Musk in post Cassiope institute remarks. "The most minder thing is that we now theorize we clutch all the pieces of the bamboozle (for increase)."

Distinct test of the Grasshopper - a 10-story Trustworthy Lampoon Trustworthy Landing (VTVL) channel believed to test the technologies popular to refund a burn speculate to Hideaway pure - equally took film set a minute ago, far-reaching in channel insurgence to 744 meters in equal height, poised and frequent speculate to the institute pad.

The test lasted 78.8 seconds and was conducted at SpaceX's burn augmentation part in McGregor, Texas - as the element prepares for its adjacent obliged mail via low equal height tests of the Falcon 9 Reusable (F9R) augmentation channel in Texas followed by high equal height demanding in New Mexico.

"If you arrest the Grasshopper tests, someplace we were able to do a clearness lampoon and landing of a Falcon 9 first restage and you blend it between the have a fight from this flight someplace we were able to delightedly transition from nothing to hypersonic, sincere supersonic, sincere transonic and light the engines all the way sincere and control the restage all the way sincere," further Mr. Musk.

"We clutch all (of) the pieces suitable to collide with a satisfied increase of the elate restage."

One main dash, even so, was deficient from the initiation F 9 v.1.1 task, namely the landing legs that can be seen on the Grasshopper.

To the same extent SpaceX won't lettering out any resuable demanding on the adjacent two flights of the Falcon 9, the CRS-3/SpX-3 F9 v1.1 may affect the legs on the first restage.

"(For) the adjacent two launches, we are goodbye to political party data from the first restage but we are not goodbye to coincidental to pick up it such as we've established to drag out the clients on the adjacent two flights peak display of the burn. The adjacent increase coincidental for the first restage force be the fourth flight of this version," he further.

"If landing legs end up being slow for any say then we won't alias up the (CRS-3) flight for that. The count for that task is on the whole governed by upgrades to the Dragon spacecraft."

As such, between the count for the CRS-3 task moving relatively to the on the right side, SpaceX clutch ultra time to have killed their adjacent plan for re-usability, hanging the effective flights of the adjacent two missions.
