DemoFlight 2 Updates
MINOR UPDATE
All Falcon 1 parts have been shipped to the launch site to prepare for next flight. Our current schedule calls for a static fire in mid January and first flight countdown in late January. Given the many upgrades to Falcon 1, there may be many countdowns before launch occurs.
We recently completed our first major pre-launch milestone, the Flight Readiness Review (FRR). This confirmed that all Vehicle, Payload, Ground Support Equipment, and Personnel are ready for launch. Following the FRR, the Falcon 1 was rolled out to the pad and we completed our wet dress rehearsal, which is a full countdown that holds approximately one minute before T-0.
The upgrades to the vehicle, Kwajalein launch facilities and our launch procedures have proven quite effective, and we have had a relatively smooth launch campaign up to this point. A number of non-critical issues arose during the wet-dress and are being resolved, but we have seen nothing to date that should delay our launch schedule.
Going forward, a static fire is planned Thursday, January 18 (California time). We have a launch window on January 21 and 22 (California time) and are working with the range to secure a couple of additional days as contingency. Should we go beyond that, which is still a good possibility as we work with the upgraded vehicle, pad, and procedures, the next available launch window is mid February.
There will be a live webcast and a media call in line for the launch. Details will be provided shortly.

The static fire has moved to Friday (California time) and launch to Monday, January 22. We have not encountered any new issues — the shift in timing is primarily to provide for additional risk reduction activities on site, as we continue to operate with a healthy paranoia.
As stated in the prior update, there is a high likelihood that the dates will continue to change, given the broad array of vehicle robustness upgrades. This will remain true all the way up to the final few seconds of the countdown, as our new health verification software executes hundreds of systems checks between engine ignition at T-3 sec and liftoff at T-0, when the hold down clamps release the rocket for flight. This is a critical phase for verification, given that the vehicle will have undergone substantial state changes throughout the first stage and avionics system.

During our final check-outs prior to static fire, we uncovered an anomaly with the thrust vector control (TVC) pitch actuator on the second stage that will result in launch being pushed to February. Since this is not used during the static fire, we have decided to push forward with that test in order to acquire valuable data on engine ignition, pad acoustics, and the overall system response. The static fire is now planned to occur between Saturday and Tuesday (California time). This test will proceed very slowly and then only burns for about four seconds, so will not be webcast to avoid boring people silly. We will post a video afterwards.
Upon completion of the static fire, we will take the rocket back into the hangar to thoroughly investigate the TVC issue. With the range available to us only until January 23 (Kwaj needs to reconfigure for an incoming Minuteman mission), this means launch is now planned for mid-February. As I’ve mentioned previously, don’t hold your breath for this launch. Given the large number of robustness improvements and the fact that our vehicle/pad health verification system has increased from about 30 checks to almost 1000, shifts in the launch date are to be expected. Overall, the SpaceX team is quite happy with the smooth progress so far.

In an excess of caution, we decided not to proceed with the static fire this month. The vehicle is now back in the hangar, where the stages are being demated for careful inspection.
The static fire and launch window is now mid to late February, due to Kwaj having to configure for an incoming Minuteman and then reconfigure back to handling a Falcon launch. During this downtime, we will take the opportunity to go over every inch of the rocket with a microscope again.

ADDITIONAL FALCON 1 FLIGHTS IN 2007
After the upcoming demonstration flight, Falcon 1 is scheduled to launch a satellite for the US Navy Research Laboratory (funded by the Office of Force Transformation) in late summer and then a satellite for the Malaysian Space Agency late in the year. We are also building an additional Falcon 1 vehicle in the event that some promising customer discussions culminate in a fourth Falcon 1 launch this year.

We have recently been informed by the Kwajalein Army Range that they do not have sufficient resources to support our launch in mid to late Feb. Several range personnel critical to the launch safety process will be unavailable in that timeframe. The earliest launch window available from the Range now opens March 9.
