Falcon 9 Flight 1



--------------------------------------------------------------------------------

First Stage Engines

Engine testing for the inaugural Falcon 9 flight proceeds at a rapid pace with no major problems or concerns. Six of the nine first stage flight engines have completed acceptance testing and all nine flight engines are on schedule to complete acceptance testing by mid July.

Second Stage Engines

Our Merlin Vacuum engine (MVac), which powers the Falcon 9 second stage, entered development with a skirt temperature too hot for flight, but we have since tuned down the engine and brought the nozzle temperature within flight specifications. The MVac will complete development by month's end, with qualification testing to follow in July.

Launch Operations

A key objective of taking Falcon 9 vertical at the Cape earlier this year was to validate ground systems interfaces and operations with the vehicle in its final flight configuration, prior to executing the launch campaign.


First Falcon 9 vehicle at Cape Canaveral's Space Launch Complex 40, former launch site of the Titan IV rocket.



The successful operation allowed us to validate several key interfaces and operations including:

• Mechanical functionality of the erector and its physical fit with the vehicle
  
• Integration tooling interfaces and function
  
• Ground system control interfaces
  
• Environments testing
  
• Hydraulic systems testing
  
• Logistics, shipping and equipment handling
  
• Vehicle integration/mating operations (fairing, stages, erector)
  
• Vehicle lifting operations
  
• Launch mount operations

Since that time, our RP-1 system has become operational, the cryogenic liquid oxygen handling system is nearing completion, and we have completed construction of our horizontal vehicle integration hangar. The Transporter Erector is getting reassembled into flight configuration and will be back into system level testing in mid July.

Our 125,000 gallon liquid oxygen storage sphere (shown below) and supporting pumping station are nearing completion and will undergo cryo shock testing in early July. Next up for completion at the launch site will be auxiliary systems like TEA-TEB handling, spin start support systems, engine purge and launch pad water deluge systems, and helium chill systems.








Structures

In preparation for the inaugural Falcon 9 flight, our Structures team is hard at work with qualification of the Falcon 9 primary structures. The Falcon 9 first stage with interstage is currently loaded in the structural qualification stand at our Texas facility. Qualification testing is expected to be complete by month's end and we expect to have fully qualified first and second flight stages at SLC-40 by end of summer.

largest test stand, used last November for our successful nine engine mission duration test firing.



The Falcon 9 truss and skirt assembly is complete and loaded in the structural test stand at our headquarters in Hawthorne, California. System checks begin today and proceed into qualification loading later this week. The entire test series will take about 3 weeks to complete.



Pending installation of the transfer tube, our Falcon 9 Flight 1 first stage tank will be completed this week, travel to Texas for proof and leak testing, and then move on to integration. Second stage tank build progress continues with secondary structure installations, and the Falcon 9 fairing build continues as well, with final assembly to start in approximately three to four weeks.



Progress continues on the hardware for Flight 2 of Falcon 9, which will feature our first demonstration flight under the COTS program of the Dragon spacecraft. The friction stir weld process is nearly complete for the second stage tank and the Falcon 9 interstage is in final assembly. In addition, skirt panels are complete through the layup process and ready for assembly integration.



Avionics

Development of the avionics suite for Falcon 9 and Dragon is nearing completion, with key units in final qualification testing and others in production.

Units already in production include:

Remote Input/Output modules for Merlin engine control
10 Mbit/sec network switching nodes for Falcon 9 and Dragon
High-energy-density Lithium-polymer batteries


SpaceX-developed CUCU (COTS Ultra high frequency Communication Unit) radio transceiver undergoing testing in Avionics' EMI (electromagnetic interference) test chamber.



In addition, the COTS UHF Communications Unit (CUCU), a dual-redundant digital communications link for Dragon and the ISS, has passed qualification testing and four units are in production. CUCU units on Dragon and the ISS will provide radio communication between the two space vehicles during final approach and berthing of Dragon. The first CUCU production unit is scheduled to be transported by NASA to the ISS aboard the Space Shuttle in late 2009.

McGregor, TX (July 29, 2009) – Space Exploration Technologies (SpaceX) announces the successful completion of qualification testing for the Falcon 9 launch vehicle first stage tank and interstage. Testing took place at SpaceX's Texas Test Site, a 300 acre structural and propulsion testing facility, located just outside of Waco, Texas.

The first stage tank and interstage hardware were subjected to a proof test of 1.1 times the maximum expected operating pressure (MEOP), and a burst pressure proof test of 1.4 MEOP; qualifying both articles with a 1.4 factor of safety. The 1.4 factor of safety designation means that the first stage tank and the interstage can withstand 140 percent the maximum internal pressure expected during flight, and qualifies both pieces of hardware to meet human rating safety requirements, as defined by NASA. The first stage also passed this human rating milestone when subjected to structural bending tests.

The testing regimen included over 150 pressurization cycles, exceeding the number of required life cycles by more than 100. In addition, the first stage and interstage were subjected to stiffness tests, maximum dynamic pressure loading and main engine cutoff conditions; all at expected values, as well as ultimate loads.

"Falcon 9 continues to pass qualification testing in preparation for its first flight, scheduled for 2009," said Elon Musk, CEO and CTO of SpaceX. "All hardware was designed to be man-rated, and these tests confirm that SpaceX is one step closer to flying humans on the Falcon 9/Dragon system."

Falcon 9's first stage and interstage also passed ground wind qualification tests, critical for when the vehicle is vertical on the launch pad at Cape Canaveral Air Force Station in Florida. Both components were designed, built and tested by SpaceX.

SPACEX DELIVERS HARDWARE TO CAPE CANAVERAL IN PREPARATION FOR FLIGHT ABOARD STS-129 AND INTEGRATION WITH THE INTERNATIONAL SPACE STATION


Hawthorne, CA (September 1, 2009) – Space Exploration Technologies (SpaceX) announces delivery of the Commercial Orbital Transportation Services (COTS) Ultra High Frequency (UHF) Communication Unit to NASA's Kennedy Space Center in preparation for launch on Space Shuttle Atlantis, STS-129. The unit will be delivered by Atlantis to the International Space Station (ISS) and integrated in preparation for SpaceX's future flights to the orbiting laboratory.

Developed by SpaceX, in collaboration with NASA, the unit allows for communication between the ISS, SpaceX's Dragon spacecraft, and ground-based mission control. The system also allows the ISS crew to monitor an approaching or departing capsule. As part of NASA's COTS competition, SpaceX will conduct flights of the Falcon 9 launch vehicle and Dragon spacecraft, culminating in Dragon berthing with the ISS and then returning to Earth.

The unique public-private partnership created through the COTS program will allow SpaceX's Dragon to serve as a replacement for cargo transport to the ISS when the Space Shuttle retires. Upon completion of the COTS requirements, SpaceX will begin to fulfill the Commercial Resupply Services (CRS) contract, awarded by NASA in late 2008. The contract includes 12 cargo flights between 2010 and 2015 and represents a guaranteed minimum of 20,000 kg to be carried to the ISS. Dragon will deliver pressurized and unpressurized cargo to the ISS and return pressurized cargo back to Earth.

"SpaceX is pleased to have delivered the two-way communication system to the Cape in preparation for flight to the ISS," said Gwynne Shotwell, President, SpaceX. "The unit had to pass NASA's strict ISS safety standards and reviews, demonstrating our progress under the COTS program and laying the groundwork for future F9/Dragon flights to resupply cargo and possibly crew to the ISS when Shuttle retires."

Space Shuttle Atlantis is scheduled for launch no earlier than November 12, 2009, from Kennedy Space Center's Launch Pad 39A.

merci steph tu m'as devancé j'allais posté cette news

[Invité]

Petit passage qui m'avait échappé, la capsule Dragon a été conçue dès le départ avec le vol habité à l'esprit.
Toujours selon SpaceX la qualification pour transporter un équipage prendrait 3 ans à partir de la prise de décision. 18 mois seraient nécessaires pour développer la tour d'évacuation et 12 mois supplémentaires pour les essais d'évacuation. Le premier vol aurait donc lieu au bout de 2ans1/2 avec 6 mois de marge.

[Wakka]

Steph, ca veut dire au pire pas avant debut 2012 alors ?

[Invité]

3 ans à partir du moment où le contrat est attribué. A l'heure actuelle seule la NASA pourrait attribuer un tel contrat, et ce n'est pas prévu.

[Wakka]

ok merci

Et puis ce délai de 3 ans fait l'hypothèse que la Falcon 9 et la capsule Dragon "de base" fonctionnent.

[Pline]

Cela me parait bien optimiste. Jusqu'à présent SpaceX n'a jamais été très respectueux de ses engagements calendaires. Pas de raison que cela change, d'autant plus que l'exercice est beaucoup plus difficile que de construire un lanceur en utilisant des technologies qui remontent à 50 ans.

Plus généralement les chantres du libéralisme dans le domaine de la construction astronautique sont victimes de l'air du temps et devraient se pencher sur l'histoire des expériences de ce type. Pas de quoi pavoiser. Quand Boeing, constructeur de la Delta IV est placé en chevalier blanc face au projet Ares I , quelle est la part de lobbying insidieux ?

Question : Comment devions millionnaire dans l'industrie spatiale ?
Réponse : En étant milliardaire.

SPACEX HOSTS PRELIMINARY TRAINING FOR NASA ISS ASTRONAUTS IN PREPARATION FOR
DRAGON SPACECRAFT RENDEZVOUS AND STATION BERTHING

Hawthorne, CA – December 3, 2009 – Space Exploration Technologies (SpaceX) recently conducted its first Dragon spacecraft operations training for a group of NASA astronauts and personnel at its corporate headquarters in Hawthorne, CA. The October training focused on how the crew will interface with the Dragon spacecraft while it is approaching and berthed to the International Space Station (ISS). Three of the participating astronauts—Tracy Caldwell Dyson, Shannon Walker and Douglas Wheelock—will be on board the ISS when Dragon makes its first visit under the Commercial Orbital Transportation Services (COTS) program.

The astronauts were briefed on vehicle ingress and egress, habitability of the spacecraft, payload handling and commanding through SpaceX's Commercial Orbital Transportation Services (COTS) Ultra High Frequency (UHF) Communication Unit. The training was a key step in SpaceX's progress towards providing NASA an alternative for cargo transport to and from the ISS when the Space Shuttle retires.

“This was the first time the NASA astronauts who will interact with Dragon during its early missions were actually inside a Dragon flight vehicle” said Elon Musk, CEO and CTO, SpaceX. “SpaceX was honored to host the ISS crew for this preliminary training exercise, and we look forward to serving NASA further under the COTS program and CRS contracts.”

Also in attendance were NASA astronauts Marsha Ivins and Megan McArthur, as well as other key NASA personnel from the NASA Astronaut Office and Mission Operations Directorates.

Under the COTS program, SpaceX will execute three flights of the Dragon spacecraft. Dragon will pass in close proximity to, and berth with, the ISS as part of the second and third COTS missions, respectively. Upon completion of these demonstration flights, SpaceX will begin to fulfill the Commercial Resupply Services (CRS) contract for 12 cargo flights between 2010 and 2015 and represents a guaranteed minimum of 20,000 kg to be carried to the ISS.

Tu n'as pas mal lu : c'est tout à fait ça.
Les astronautes, dont certains seront dans l'ISS lorsque la capsule Dragon fera ses vols de qualification (si le planning est tenu bien évidemment), ont pris connaissance de l'engin. C'est très habituel. Ainsi pour l'ATV et le HTV, les astronautes sont aussi allé voir les engins, histoire de ne pas être surpris là-haut...

Imaginez ce qui pourrait se passer sans ce genre d'entraînement :
"Ha bon ? C'est là ce truc ? Et ce machin, si j'appuie dessus, ça fait quoi ? Oups ! Houston ! Houston !" :megalol:
