Big launch panel coming up at #WSBW, with executives from Arianespace, Blue Origin, ILS, MHI, SpaceX and ULA.
SpaceX’s Tom Ochinero: trying to get to a little over 60 launches this year, and 100 next year. Includes 6 Falcon Heavy launches in next 12 months.
Tiphaine Louradour, ILS: both the US and Russian governments could choose to end ILS if they chose, but we believe they recognize this venture has value. (But who will buy Proton launches these days?)
Stéphane Israël, Arianespace: we have a settlement with OneWeb for 6 cancelled Soyuz launches; look to work together on Gen 2.
Jarrett Jones, Blue Origin: last 12 months have been critical for New Glenn; “over the hump” on qualification and plans to get to first launch.
Iwao Igarashi, MHI: found good solution to turbine vibration problems in engine for H3, proved it was effective. First H3 launch now projected this fiscal year (ends March 31); will announce date after static-fire tests in November.
Mark Peller, ULA: making good progress on Vulcan, should get BE-4 flight engines in the “coming weeks” and then send it to the launch site. (Does not commit to a specific launch date for first Vulcan launch.)
Israël: like to end the Ariane 5 with the launch of JUICE in April 2023. Will discuss later this month plans on transition to Ariane 6 next year.
Peller: can reconfigure SLC-41 at the Cape between Atlas and Vulcan in a day or so, enables overlap over the next couple of years.
Louradour: we have Protons at the launch site, ready for payload integration. Hope for much broader reasons this situation will resolve and can engage with community again.
Israël: look for a role in Artemis with Ariane 6 launches of proposed European EL3 lunar cargo lander; hope to convince NASA and ESA to go beyond that.
Ochinero: Starship launch of GEO communications satellite, recently ordered, will not much different than what we traditionally do for such missions.
Jarrett: first New Glenn launch will be “as soon as we’re ready” but no specifics beyond some time next year.

Peller: have a plan to launch Vulcan before the end of the year, but depends on s/c readiness. Narrowing down on launch date soon.
Jarrett: still “super early” into New Shepard launch failure investigation. Not prepared to say it’s a problem with the BE-3 engine (which would have implications for New Glenn’s upper stage.)
That’s it for the panel.

In a #WSBW finance panel, Peter Cannito of Redwire Space says a drop in valuations of space companies “creates an opportunity for companies like ours” that has acquired such companies in the past.
Vaibhav Lohiya, Deutsche Bank Securities: consolidation for the sector is good; helps companies reduce and rationalize capital expenditures. Also growing interest in vertical integration to secure their supply chains. #WSBW
Lohiya, on rumors of an SES-Intelsat merger, notes it would make sense for rationalizing their fleets and reducing long-term capex. A challenge is that Intelsat is not considered “investment grade” given its recent Ch. 11 restructuring. #WSBW

Coming up on 10 minutes before the launch of Firefly’s second Alpha. Presumably launch preparations are going well, but few specific updates during this lengthy pre-launch webcast.
T-3 minutes.
Go for launch at T-2 minutes.

NASA’s Jim Free: requesting dates of Sept. 23 and 27 on the Eastern Range for next Artemis 1 launch attempts. Still working with the Eastern Range on a waiver for FTS battery retest. Proposed dates avoid DSN conflicts with DART impact on Sept. 26.
Mike Bolger, Exploration Ground Systems program manager, says work is underway to replace seals on two liquid hydrogen lines. Work could be done by the end of the day today if weather holds. That would support another tanking test Sept. 17.
Bolger says they don’t know yet if the inadvertent overpressurization during Saturday’s attempt damaged the seal. It did not exceed hardware specs, though.

Jim Free: will not in this launch period, which ends Tuesday. What happens in next two periods (late Sept/early Oct, and mid-late Oct) will depend on options the team comes up with by Monday or Tuesday.
Mike Sarafin: inadvertent overpressurization of hydrogen line during chilldown. Can’t rule out the quick-disconnect fitting saw some effects of that, but too early to tell.
Sarafin: ruled out doing a demate and remate at the pad. Looking at options to remove and replace the quick disconnect fitting at the pad or in the VAB.

One more Artemis 1 prelaunch briefing, starting shortly, with updates on launch preps.
Launch weather officer Melody Lovin says weather should trend better through the 2-hour launch window: 60% go at the start to 80% at the end.
For backup day Monday 70% go, but a little more uncertainty.
She adds there could be showers around the time taking starts, but difficult to predict. Any delays in tanking is not necessarily a minute-for-minute launch delay, says Jeremy Parsons, deputy manager of exploration ground systems.
