FAA has delay again evaluation of Starbase Permission to launch Orbital to May 31 2022...

My reaction on that news...
That’s because Space X made multiple changes to their application to the FAA.

SpaceX moved NROL-85 from the Cape to Vandenberg at no extra cost, in exchange for reusing booster

The National Reconnaissance Office’s NROL-85 mission launched April 17 by SpaceX was originally scheduled to fly from Cape Canaveral, Florida. But just 12 months before the launch, the NRO informed SpaceX it needed to send its payload to a different orbit so the launch had to be moved to the western range at Vandenberg Space Force Base, California.

“This was a challenge,” NROL-85 mission manager Maj. Jonathan Schirner said this week on the NRO’s “The Dish” podcast.

National security space launch missions are rarely, if ever, moved from coast to coast on such short notice, Schirner said. “It’s the first time we’ve done a range change at the 12 month mark in the NSSL timeframe.”

The NRO and SpaceX worked out a deal to move NROL-85 to the West Coast at no extra cost to the government and in exchange the NRO agreed to fly the mission on a reused first stage that had previously flown another NRO mission.

Under the agreement, SpaceX would launch NROL-87 in February at Vandenberg and reuse the boost for NROL-85 in April. Schirner said the deal also was possible because the Space Force’s Space Systems Command was able to examine the recovered booster and approve it for reuse in just two months, a much shorter than usual turnaround.

More details on the private Polaris Dawn mission.

The Polaris Dawn mission will likely target a peak altitude of about 870 miles (1,400 kilometers), higher than NASA’s Gemini 11 mission crewed by commander Pete Conrad and pilot Dick Gordon in 1966, which set the altitude record for an astronaut flight in Earth orbit at 853 miles (1,372 kilometers), according to NASA.

“There’s very little reason to go much higher than 1,400 kilometers,” Isaacman said. “You’re just dramatically increasing radiation (exposure), and you probably won’t learn a whole bunch more from it. We’re already anticpating getting a lot of really good data after just a couple of laps at a 1,400-kilometer orbit. I don’t expect to go much farther than that.”

Seems someone plan to have a lot of fun (firing thrusters to reach 1400km and then firing them back to descent to a much lower altitude for an EVA)!

They won’t alter the orbit for that just use the initial elliptical orbit. They’ll only lower it when they are getting ready to return.

@Flyaway : The exact quote does not leave much ambiguity ;) :

The Dragon capsule will fire Draco thrusters to lower its altitude before the spacewalk.

The spacecraft doesn’t have an airlock, so the spacewalk will require the entire capsule be depressurized in space. The crew members will float out of the hatch and remain tethered to the spaceship at an altitude of approximately 300 miles, or 500 kilometers, according to Polaris Program website.

112th recovery of First stage
I have strong feeling, that these recoveries soon became more frequent, then launches!
On serious note: nice to see, how stable are SpaceX' production process, they made launches conventional and predictable business. And keeping the strong amount on the further development of more advanced technologies. Hope, this combination helps to further improve space industry around the world.
