FULL STORY ======================================================================
 The Federal Aviation Administration (FAA) has approved SpaceXs Flight 7 of  Starship. The news came shortly after Ship 33 completed engine testing at  Masseys and rolled back into Mega Bay 2. SpaceX must now put the final 
touches on its vehicles before teams are ready. 
 
 
 Flight 7 Regulatory Side 
 On Dec. 17, the FAA released a statement for the approval of Flight 7 and a  minor license modification. This comes a bit earlier than expected and just  before the holidays. NSF has asked the @FAANews about the license 
notification for Flight 7 of Starship. That modification has been given:  pic.twitter.com/GRDeJkvA9i

The first part of the statement allows SpaceX to use the Flight 7 mission  profile multiple times. This refers to using a Block 2 Ship and Block 1  Booster on a suborbital trajectory. While the trajectory is the same as in 
the past six flights, the vehicle combination has changed due to Block 2 of  Ship. This could mean that SpaceX still intends to fly suborbital missions 
for a few more flights or at least has the option to do so without another  license modification. 
 The FAA also discusses how the agency continues to increase its licensing  duties efficiency to try to meet the demands of the commercial space 
industry. Considering the rapid turnarounds of the past few license  modifications and the timely return to flights for Falcon 9 throughout the  year, the FAA is undoubtedly making progress. 
 The licenses basic verbiage regarding the vehicle configuration for the  flight is: Using the Starship-Super Heavy vehicle. This has been the same  since Flight 5 and has only been changed once which was for Flight 4 where it  stated, Using Ship 29-Booster 11Starship-Super Heavy vehicle Configuration,  unless this license is modified to remove this term. This definition might  cover SpaceX at least through the end of Block 1 of Booster. 
Regarding Block 2 of the Ship, it was thought that due to the extended tanks  and many other changes, a significant modification might have been required  for Block 2 of the ship. However, it appears that the FAA has deemed the  current definition of the vehicle to cover the changes in design. Revisions

 The only changes to the license were the addition of Paragraph 12, which is  Highly Reliable Flight Safety System Tailoring, which then states: SpaceX 
must receive FAA signature on RCC-324-11 tailoring change request,  TR24-001-STARSHIP, prior to initiation of Flight 7. RCC-324-11 is for Global  Positioning and Inertial Measurements Range Safety Tracking System 
Commonality Standard. This means that before Flight 7, SpaceX must update its  document for Range Safety and Tracking. 
 This standard is used by many ranges across the United States, such as the  White Sands Missle Test Range and the 30th and 45th Space Wings, which are  located at Vandenburg Space Force Base and Cap Canaveral Space Force Station,  respectively. This is for standardizing range operations for Starship in Boca  Chica, Texas. 
 SpaceX operates Starship under Part 450 of Title 14 of the Federal Aviation  Regulations. Under Part 401.7 are the definitions of what constitutes a 
Mishap during any given launch under Part 450. Mishap Definitions (Credit:  Federal Aviation Regulations) 
 So far in the program, the FAA has allowed SpaceX to have specific failure  modes that would not trigger a mishap investigation, as things are still  experimental and are a work in progress. To date these were failure of the  thermal shield during high heating, failure of the flap system during high  dynamic pressure, and failure of the Raptor engine system during the Starship  landing burn. 
 For Flight 7 and beyond, the FAA has added two new failure mode exceptions:  first is the failure of the Raptor engine system during in-space 
demonstration burn, and second is the failure of Super Heavy systems during  post-booster catch vehicle safing. These additions allow SpaceX to try  different things with in space burns and with post-catch safing and not have  to have a mishap investigation if there were to be a failure. However, an  investigation will be required if any of these failure modes cause a safety  issue or injury. Booster 12 on the OLM after being Safed (Credit:

 Flight 7 Vehicles and Pad 
 With the regulatory part out of the way, SpaceX must now focus on vehicle  readiness. To that end, Ship 33 completed a couple of engine tests at 
Masseys. The first was a spin prime on Dec. 12. The reason for doing a spin  prime is that Ship 33 has upgraded engine plumbing from Block 1 ships, and  SpaceX needs to verify it before proceeding to a static fire test. On Dec 14,  Ship 33 did tank up as if it were to possibly static fire but either aborted  or SpaceX was performing another type of test. 
 On Dec. 15 and 16, SpaceX performed two static fires of Ship 33; the first  test was a full six-engine static fire, and the second was a single-engine  static fire testing the deorbit burn with some engine gimbaling added. Ship

 Once these tests were completed, Ship 33 was then rolled back to Mega Bay 2  for final flight preparations. So far, SpaceX has not stripped the side tiles  off Ship 33 like Ship 35, which is already being built with this modification  in mind; however, that should only take a week or two to complete. 
 Booster 14 has been back in Mega Bay 1 for over a week since completing its  engine testing and is not expected to require much work other than installing  its Hot Stage Ring, then rolled out and stacked in Mega Bay 1. Rollout to the  launch site for flight could possibly be just after the holidays. 
 Regarding the launch pad, SpaceX should have completed most of the  refurbishment work, but the legs still need to be repainted, among other  things. The new tanks that have been added over the past few weeks will 
likely not be anywhere near ready for Flight 7 as SpaceX still has to route  the cryogenic pipes and hook them into the Orbital Tank Farm. Pad A being  Refurbished For Flight 7 (Credit: BocaChicaGal for NSF) 
 Once rolled out and stacked, SpaceX will likely perform at least a tanking  test, if not a full Wet Dress Rehearsal, considering the changes on Ship 33,  with it being the first Block 2 ship to hook into the Orbital Tank Farm. 
 If everything lines up, SpaceX could hit a launch target around Jan. 11, the  latter cited as the target date for NASA to be in Perth, Australia, for a  Starship flight. This is a plane that NASA uses for imagining purposes, which  also means SpaceX might go for another late-day flight so pictures can be  taken in sunlight at the landing zone.
