JSCAT 18/Kacific1 Recovery Discussion and Updates Thread
Hello! It is I, u/RocketLover0119 back hosting the recovery thread for the JSCAT 18/Kacific1 mission. As of now, core B1056.3 has been safed to the droneship Of Course I Still Love You, fairing catch was narrowly missed this attempt.​B1056.3 on the deck of OCISLY following its third launch and landingAbout the mission" Boeing built the JCSAT-18/Kacific1 satellite, equipping it with two unique payloads. The JCSAT-18 satellite was built for SKY Perfect JSAT, one of the largest providers of multichannel pay TV broadcast services in Japan, which operates the largest satellite communications business in Asia. The JCSAT-18 satellite will provide Ku-band coverage and improve mobile and broadband services for SKY Perfect JSAT Corporation customers in the Asia-Pacific region, including the far eastern part of Russia. The satellite features technologies in the power subsystem to achieve highest efficiencies, and it also features command and data handling technologies to provide a more secure spacecraft. Boeing has built 13 satellites, including two high-throughput satellites, for SKY Perfect JSAT Corporation and its predecessors since the 1980s. Kacific1 is a next-generation geostationary satellite operating in the Ka-band frequency spectrum. Its 56 high-throughput spot beams will place capacity over selected regions in South East Asia and the Pacific Islands. Deployed to a geostationary orbital position above Asia Pacific, Kacific1 will transmit to stateof-the-art gateways, designed and built by Kratos. Kacific1 will connect previously unserved or under-served populations with affordable, high-speed broadband for healthcare, education, government services, businesses, and disaster relief. Its services will stimulate economic growth and provide greater access to the internet.

Future demand prediction for SpaceX, is it possible to push beyond 30 customer launches per year?
Total commercial launches this year has fallen down to 11 from last year's 20 launches (launches where SpaceX is not the customer)is it the limit of the market? in some interview the Ms Shotwell said that customers were not ready in time, so they are shifted to 2020 Sourcebut still the ceiling seems to be around 20 customer launches per year (starlink will be extra), can we expect this ceiling to expand in 2022-2025 at cost of ULA or Arianne, as their pre existing contracts get over.

SpaceX engineers were at the Cali Science Center in LA looking at the Endeavour shuttle
I was talking to Bill while standing underneath Endeavour at the California Science Center in LA this last week. Bill was a structural engineer on the shuttle program as well as the SSMEs. We had been geeking out about space stuff for a solid 2 hours and Bill was complaining about ULA "Throwing his engines into the ocean" when I asked about how reentry heating effected the gaps in the bottom of the shuttle where control surfaces and landing gear panels all met up. He got excited and he told me that not only had a large group of 20+ SpaceX engineers been there last week but that they had been almost exclusively looking at the spots where the control surfaces joined the rest of the structure on the shuttle. I mentioned to Bill that they probably were cheating off his homework for the starship's control surfaces and his face lit up like it finally clicked as to why they took so many photos of the seams.Sorry for formatting I'm on my phone figured this group would enjoy this information more than most. If you have the chance go to the science center and talk to the retired engineers that are floating around. They absolutely love talking to people about their baby.
