I kinda missed what she said. Cleaning solution got caught in the piping causing the failure on last starlink launch?

Launch was pretty quiet, must have been the wind muffling the sound waves.
I can usually hear it louder and longer.

Still cool to watch though.

Yep, born in 1960, posted this many times, Blessed\Cursed with total recall memory since at least age 2.5.
My Father and I closely followed the Space Program and 'Space Race'.
My interest in that and helping my Dad repair tv's and radios eventually led me to a great career in in heavy industrial electronics, robotics, automation and instrumentation and doing a lot of .gov\.mil work.

The fourth landing for a booster is very interesting, because they haven't yet successfully landed a booster for a fifth time.

They only have two Block 5 F9 Boosters that have 4 launches & landings now.
B1049 (last launched during F9-078 'Starlink 2') & B1051 (last launched today during F9-084 'Starlink 6').

The only "Point 5" booster was B1048.
That was the one they mentioned during today's launch, that crashed doing the landing on the last Starlink mission (F9-083 'Starlink 5').


Also, today's launch makes the F9 Rocket the most flown currently operational US rocket.

Sounds so weird, for those of us that grew up in the early space years and shuttle era (not counting SRB's).  Rockets and engines were an expendable inevitability.  But not now.

Looks like a lot of boats out to watch the rocket come back.  Do they have to maintain a hazard zone around OCISLY?

Here is an article on the return.

"Baring a new layer of reentry soot and looking scarcely worse for wear, booster B1051 is now one of six Falcon 9 boosters to successfully launch and land four or more times or more. Unfortunately, B1048 and B1056 were two of those six boosters before they were lost in landing failures, while B1046 and B1047 were intentionally expended on their fourth launches.

Now B1049 and B1051 are the last operational SpaceX boosters to have completed four launches. Due to a slowed booster production rate, SpaceX will likely have to rely heavily on both four-flight boosters and B1059 to achieve its ambitious 2020 Starlink launch manifest. Three new boosters should be available for their second launches by June, September, and December, give or take, and additional new boosters could debut between now and the end of the year. In other words, SpaceX will effectively be forced to push its existing fleet of Falcon 9 Block 5 boosters to their limits (~10 flights each) to end 2020 with Starlink in a strong position."

It sounds like they need a few more new boosters.

The next Starlink launch is planned for 3 June 2020, 9:25 PM EDT

8th Starlink launch but officially Starlink 7

"Additionally, Starlink-8 is scheduled to debut SpaceX’s first “VisorSat”, a Starlink satellite modified with a visor specifically designed to prevent sunlight from reflecting off of the shiny satellites and disrupting ground-based astronomy. If successful, all future Starlink satellites SpaceX manufactures will include the modification, hopefully mitigating or wholly eliminating Starlink’s impact on astronomy. "


During a surprise April 27th Astro2020 presentation, Elon Musk revealed a conceptual render of SpaceX’s new VisorSat design. (SpaceX)

"Starlink-8 is also expected to debut SpaceX’s potentially game-changing addition of rideshare slots for small satellites aboard a large portion of the company’s planned Starlink launches. Earth imaging company Planet is the first announced customer, with three ~125 kg (~300 lb) SkySat imaging satellites manifested on Starlink-8. Potentially costing Planet just $1 million apiece, the launch option could easily become industry-leading if SpaceX can regularly include several hundred kilograms of 3rd-party satellites on each of the 20+ Starlink missions it’s likely to launch annually."


A SkySat imaging satellite. (Planet/SSL)

"Finally, Next Spaceflight says that Falcon 9 booster B1049 has been assigned to support Starlink-8, meaning that the mission will be the second time ever that a Falcon 9 booster has attempted its fifth orbital-class launch. Starlink-8 will come two and a half months after improper refurbishment caused Falcon 9 booster B1048 to suffer an in-flight engine failure during its fifth launch. While the booster changed its flight program on the fly to ensure the Starlink-6 mission was successfully completed, B1048 did so at the cost of its landing propellant, ending the booster’s productive life with a violent crash somewhere on the surface of the Atlantic Ocean."

That many ride share opportunities a year at that price point is going to pull some customers away from Rocket Lab and other prospective upstart small sat launch providers.

This is why you are starting to see RL moving into more specialized orbits. IIRC they have missions planned to the moon and Venus.

Yep.  Seems like they're finding a niche in SSO and other specialized orbits.  They'll probably be fine while others are struggling.
