Post Launch Statement
Posted September 28, 2008
Wow, this is a great day for SpaceX and the culmination of an enormous amount of work by a great team. The data shows we achieved a super precise orbit insertion — middle of the bullseye — and then went on to coast and restart the second stage, which was icing on the cake.
I will have a more complete post launch statement tomorrow, as right now I'm in a bit of a daze and need to go celebrate :)

A. Launch of the Falcon 1 Flight 4 vehicle from Omelek Island, in the Kwajalein Atoll, 2,500 miles southwest of Hawaii.
Liftoff occurred Sunday 28 September 2008, at 4:15 PM (PDT), 23:15 (UTC).

B. The critical stage separation sequence began about 2 minutes and 37 seconds into flight with shutdown of the Merlin first stage engine, then separation of the first and second stages, followed by ignition of the Kestrel second stage engine.
C. A few seconds after second stage ignition, the fairing (nose cone) that covers the payload section separates from the vehicle and falls to Earth.
D. About nine and a half minutes after launch, the second stage engine shuts down, and the Falcon 1 becomes the first privately developed liquid fuel rocket to orbit the Earth.

SpaceX Falcon 1 Flight 4 | Mission Summary In Pictures
On September 28, 2008, SpaceX made history when its Falcon 1, designed and manufactured from the ground up by SpaceX, became the first privately-developed liquid fuel rocket to orbit the Earth.

Falcon 1 Flight 4 lifted off at 4:15 p.m. (PDT) / 23:15 (UTC) from the SpaceX launch site on Omelek Island at the U.S. Army Kwajalein Atoll (USAKA) in the Central Pacific, about 2,500 miles southwest of Hawaii. It achieved an elliptical orbit of 621 x 643 km, 9.3 degrees inclination, and carried into orbit a payload mass simulator of approximately 165 kg (364 lbs), designed and built by SpaceX specifically for this mission.
Expedited delivery - SpaceX purchased a C-17 flight from the USAF to fly the Falcon 1 Flight 4 vehicle from Los Angeles International Airport to the Kwajalein Atoll, on 3 Sep 2008.

The two halves of the fairing (nose cone) of the SpaceX Falcon 1 Flight 4 vehicle fall back towards Earth. As the vehicle now travels in the vacuum of space, it no longer requires the streamlining provided by the fairings.
The fairing halves fall gracefully back towards Earth, to burn up as they reenter the atmosphere.
The second stage Kestrel engine on the SpaceX Falcon 1 Flight 4 fires for nearly seven minutes. As the vehicle passes 100 km (62 miles) in altitude, it crosses the unofficial boundary of space.
Approximately nine and a half minutes after liftoff, the vehicle travels at 7.33 kilometers per second (16,400 miles per hour) — sufficient speed to remain in Earth orbit.

After travelling half way around the Earth, the Falcon 1 Flight 4 vehicle flies over the Atlantic Ocean on the night side of the Earth, and reignites the Kestrel second stage engine. Restarting the Kestrel engine raises and circularizes the orbit to an ellipse of 621 x 643 km, where it will remain for 10 years or longer.

Flight 4 of Falcon 1
Posted September 27, 2008
Falcon 1 is currently cleared for liftoff sometime between 4 p.m. and 9 p.m. (California time) tomorrow, Sunday September 28th. Of course, if we see anything that requires investigation, the launch will be postponed, but we?ll let you know as soon as we know. As with prior flights, you can access the webcast from the SpaceX site: www.spacex.com

Flight 4 of Falcon 1
Posted September 23, 2008
The static fire took place on Saturday [20 Sep 2008, CA time], as expected, and no major issues came up. However, after a detailed analysis of data, we decided to replace a component in the 2nd stage engine LOX supply line. There is a good chance we would be ok flying as is, but we are being extremely cautious.
This adds a few extra days to the schedule, so the updated launch window estimate is now Sept 28th through Oct 1st [CA time].

Flight 4 of Falcon 1
Posted September 19, 2008
As mentioned in my update last month, we do expect to conduct a launch countdown in late September — as scheduled.
Having said that, it is still possible that we encounter an issue that needs to be investigated, which would delay launch until the next available window in late October. If preparations go smoothly, we will conduct a static fire on Saturday and launch sometime between Tuesday and Thursday (California time).
The SpaceX team worked hard to make this launch window, but we also took the time to review data from Flight 3 in detail. In addition to us reviewing the data, we had several outside experts check the data and conclusions. No flight critical problems were found apart from the thrust transient issue.
Flight 5 production is well underway with an expected January completion date, Flight 6 parts are on order and Flight 7 production will begin early next year. We are now in steady state production of Falcon 1 at a rate of one vehicle every four months, which we will probably step up to one vehicle every two to three months in 2010.
