ITS Composite Tank Construction
I realize much of this conversation might be speculative, however, I was unable to find such speculation elsewhere. I am interested in the potential manufacturing process for the 12 meter composite cryotank. I have some high level background knowledge of carbon fiber layup, but am looking for some input from those with more experience.From what I understand, it appears that each section of the tank likely consists of prepreg tape placed on the surface of a mold. These can then be cured using an autoclave or oven process. My questions are as follows.What are the possible mold configurations?
Can one mold consist of an entire cylinder (ends open) which will create the walls of the vessel as one piece? If this method is used, could the mold be removed it were metallic, or does a metallic mold require two half circle cylinders which then need to be joined? If so, can a foam type mold be used to create this section in a single piece and drilled out - or is this an amateur technique only?It appears that photos of the tank have fasteners running along the hoop direction on each side of the tank equator. If each hemisphere is created as one or multiple pieces, then joined to together, how is this joining typically completed? If with fasteners, how is this achieved/what additional parts are required to bring them together? Can they simply force each half together, then overwrap with additional tape longitudinally to join them (thereby avoiding fasteners)?
Any thoughts would be much appreciated.

Spaceflight Manifest Shows 7 Dedicated F9 Launches Through 2020 In The Works - 4 SSO, 3 GTO
Learned a lot today from a talk from a Spaceflight mission manager at the IEEE Aerospace Conference. Apologies for the potato quality photo- SpaceX details transcribed below:SSO-A - Q4 2017, 575 x 575 km SSO, 10:30 planeSSO-B - Q4 2018, 500 x 500 km SSO, 10:30 planeGTO-1 - H2 2018, 200 x 35786 km, 27.5 deg inclinationGTO-2 - H2 2018, 200 x 60000 km, 27.5 deg inclinationSSO-C - H2 2019, 500 x 500 km SSO, 10:30 planeGTO-C - H1 2020, 200 x 35786 km, 27.5 deg inclination (and away went consistent mission naming)SSO-D - H2 2020, 500 x 500 km SSO, 10:30 planeIt's unclear if missions beyond SSO-A are officially under contract, though it's not unreasonable to believe that at least some of them are, given that 2-3 years is not a whole lot of lead time in rocket land. These missions are all "dedicated rideshare," meaning Spaceflight has bought (or intends to buy) the entire F9, and then sell off payload space to smaller spacecraft (SSO-A was quoted as carrying 90 satellites).In other manifest shuffling news, SpaceIL is not flying their lunar lander with SpaceX at the end of this year as planned, due to delays on their end - they're targeting a launch in 2019 (unclear if F9 or someone else). Speaking of delays, Spaceflight manager said that he expects Formosat-5 (an F9 launch which, until recently, was to carry a ring of secondary payloads for Spaceflight on a Sherpa carrier) to launch sometime in 2017, but that Spaceflight pulled out because they were fed up with delays and had some customers who'd been delayed over 2 years, and were concerned that Formosat-5 has a low priority in the launch queue and could slip to 2018. The Sherpa payloads were remanifested to a mixture of Indian PSLV launches (some as soon as this summer) and the nominally-in-December SSO-A.Final bonus new info from Sierra Nevada Corp, who had a speaker to talk about the Dream Chaser. In its cargo configuration (which won a CRS2 contract, and will be serving cargo missions alongside SpaceX starting around 2019), the Dream Chaser is launched inside of a fairing towing an extra pressurized cargo capsule. The capsule makes the entire Dream Chaser assembly too long to fit in a SpaceX fairing, but its wings fold, allowing it to fit cross-sectionally (indeed, she said a crew Dream Chaser could probably fly on an F9, as the crew version doesn't use a fairing or tow an extra cargo pod). The speaker said that Sierra Nevada talked to SpaceX about engineering a longer fairing (and was naturally met with "sure, if you pay for it") but expects to look at it more seriously in a couple of years.(And because someone will ask, "10:30 plane" refers to a special feature of sun-synchronous orbits (SSO), which are highly inclined and due to special gravitational effects cross the equator at the same local time every day. A 10:30 orbit will cross the equator at 10:30AM on one side and 10:30PM on the other. 10:30 is particularly useful for Earth imaging satellites, as the before-noon shadows help with image processing. SSO-A has a confirmed payload of at least 6 imaging satelites for Skybox/Terra Bella/Planet [all now the same thing] and for Planetary Resources asteroid Earth imaging prototype satellite, Arkyd-6.And now when someone asks we'll know you didn't read through :P)
