Launch hold to clean the camera lens (wipe it dry).

It means that their weather GO comment earlier may have been bad as well as the Launch Director Go for Launch at T-40 seconds. |

Mission: Falcon Heavy, ViaSat 3 Americas
1) Background info: Source "A SpaceX Falcon Heavy rocket will launch the ViaSat 3 Americas broadband communications satellite. ViaSat 3 Americas is the first of at least three new-generation Boeing-built geostationary satellites for ViaSat. A small communications satellite named Arcturus will launch as a secondary payload for Astranis." 2) Launch window: 7:29 - 8:26 PM EDT (30 April 2023). 3) Launch site: LC-39A, Kennedy Space Center, Florida 4) Launch direction: Easterly 5) Webcast viewing options: a. SpaceX webcast (Starts about 15 minutes before liftoff) b. YouTube:  ViaSat-3 Americas Mission 6) Observation comments: Launch site sunset is at 7:56 PM. Civil twilight at 8:21 PM. Launch near the end of the launch window could result in jellyfish sightings. 7) Launch preparations: a. Boats heading out.  Gav Cornwell@SpaceOffshore. 21 April 2022. Departure! Doug is heading back to sea to recover the fairing halves from the Falcon Heavy ViaSat-3 mission. The ship departed previously but was later recalled back to Port Canaveral after the mission was delayed.  Gav Cornwell@SpaceOffshore. 25 April 2023. SpaceX recovery ship Doug is almost 1700km downrange (and still going) from LC-39A to recover the fairing halves for the upcoming Falcon Heavy ViaSat-3 mission. If successful, the recovered farings would hold the record for the furthest downrange distance. b. Satellites:  The ViaSat 3 Americas satellite inside Boeing’s factory in El Segundo, California.

Kind of ironic SpaceX lunching Viasat's latest sat since Starlink is going to put them out of business. The thought of Viasat going bankrupt makes me smile, I HATE them.

Quote HistoryOriginally Posted By fox2008: Why are they not planning on recovering the rockets for the Falcon Heavy launch? Probably because it’s a heavy payload going to a difficult to get to orbit. I admit that I don’t understand orbital dynamics as well as I should but the concept of geostationary orbit always gave me a headache. It’s kinda funny the way things have turned out with FH. It’s at its most useful when they use up the rocket, even with expending the rocket it’s still cheaper than its contemporaries. I should look up the price difference between a FH and Delta IV launch. |

Correct, they are going to a near-geosynchronous orbit, not a more common elliptical transfer orbit. They need all the propellant to do that. Look at the third set of second stage burns over four hours after launch. That is the one that ideally will circularize the orbit and remove most of the inclination. After they launch it and element sets show up I will post some numbers to show what happened. |

Thanks for that. I saw the flare up at landing but did not know why. Notice the venting of a gas just above the landing legs. It is directed downward and when it reaches the engine area is ignited. |

Makes sense.....but still sucks we don't get to see 2 boosters landing at the same time.

FH expendable shows $90-$150 million for 59,000 lbs to GTO. Delta IV heavy is $440 million for 29,500 lbs to GTO. |

The only thing that SpaceX hopes to recover is the payload fairings, which has become routine but this time it's a bit different. This mission will be the farthest out they have gone to fetch them.

Reportedly there are some changes to something on SLC-39A to change between Falcon Heavy and CRS/Dragon missions. It just reinforces the fact that 39A is a single point failure for ISS supply and manned flights. I believe that SLC-40 is going to be modified to handle those missions.
