    I don't know if they really lost a lot of time with that. Integration tests also have to happen at one time or another.
    With sufficient thrust, water towers fly just fine.

    I like the two flat design--it makes it more modern--less tintin-like.

    Past and future both.

    I wonder if the folks at The Boring Company knew about the Terrajet of Zwicky,

    The Boca Chica Mk1 propulsion module was moved onto an open framework steel platform. Maybe to give clearance for finishing landing leg work and get better ventilation?

    New renders of #Starship and #Superheavy. Quite a sight.

    Think I've outdone myself here, especially on the inflight one.

    With a base cost of $1m for a 200kg payload, this is going to put big pressure on the small launcher outfits.

    SpaceX says rideshare missions will launch on time, even if partly empty

    MOUNTAIN VIEW, California — SpaceX plans to launch regular Falcon 9 rideshare missions starting in March and won’t delay launches for tardy customers, a company executive said Oct. 8.

    Tom Ochinero, vice president of commercial sales at SpaceX, said that the launch provider learned the importance of setting firm departure dates for rideshare missions by seeing the challenges customer Spaceflight had coordinating the 64 satellites that ultimately flew on the SSO-A mission SpaceX launched in December.
    >
    Ochinero, speaking at the Satellite Innovation 2019 conference here, said SpaceX won't stop mission timelines to fill empty space or wait for late smallsat operators.
    >
    SpaceX's first self-managed rideshare mission, a Falcon 9 mission to sun-synchronous orbit, is scheduled for March. After that, SpaceX intends to launch dedicated rideshare missions to sun-synchronous or polar orbits every quarter.

    SpaceX now has TWO vessels capable of recovering Crew Dragon; GO Searcher and GO Navigator.

    And in a rather ambiguous tweet Musk simply said "A Shortfall Of Gravitas." Will it still be a droneship? "Yes"

    Starship capable? We'll see.

    The "concept" is the development of docking connectors for the propellant transfer lines.

    https://www.floridatoday.com/story/t...ns/3957775002/

    If SpaceX wants its massive next-generation spacecraft to reach the moon and planets beyond, CEO Elon Musk says it'll need to be refueled in orbit around Earth - and NASA wants to know more.
    >
    To further the technology, NASA recently awarded SpaceX a $3 million contract to study the concepts, Administrator Jim Bridenstine said during a joint press conference with Musk on Friday.
    >
    "Starship is a really big vehicle," Bridenstine told FLORIDA TODAY on Thursday. "Being able to refuel it will be necessary to become a vehicle that can get to the moon."

    "SpaceX can use it for their reasons and we can use it for our reasons,"

    Ok, I have a possibly stupid question.

    I've gotten the impression that Starship is incapable of going beyond LEO, even as far as the moon, without refueling on orbit, a technology which does not currently exist and sounds fraught with peril. What's the point? What am I missing?

    Oh, something else that's bugging me: They show it launching from this tall platform. How the heck do they plan on lifting Starship all the way up there, on top of the SuperHeavy booster?

    I thought there were some limited scenarios where it could at least do a lunar orbit without refueling, but my understanding is that yes, it would need to do a refuel generally for beyond LEO. And yes, the technology needs to be developed, but they are working on it.

    Florida Today

    If SpaceX wants its massive next-generation spacecraft to reach the moon and planets beyond, CEO Elon Musk says it'll need to be refueled in orbit around Earth – and NASA wants to know more.

    Now in the prototype and early test flight phase, Starship is a stainless steel crewed craft that will launch atop a Super Heavy booster. But because of its size and potentially heavy payloads – like dozens or hundreds of astronauts – in the future, it will need to be refueled in orbit around Earth before it begins longer voyages.

    SpaceX, Musk said, is developing the technologies necessary to dock two Starships together in orbit – one without much in the way of crew or payloads – and transfer fuel to the one venturing beyond low-Earth orbit.

    It should be able to go direct to GEO (or at least a near-GEO GTO) with a payload comparable to current GEO sats. It can also manage a free return lunar trajectory. It's much less limited than the Shuttle was, even without refueling.

    As for refueling, NASA's been using it as an excuse to avoid doing stuff for ages now, just as they did with supersonic retropropulsion. There's no reason to think it'll be that difficult to work out, especially with the mass budgets Starship allows.

    Moving Starship would likely be done with the same commercial many-wheeled transport platform they're already moving the prototypes around with, stacking will be done with a moderately large crane.

    The full-stack launch pad will have an enormous vertical integration crane tower. It'll lift Super Heavy, then Starship, into launch position. Each will have a transporter. Passengers boards through a crew access arm similar to LC-39A's.

    -------

    Starship should be able to do a lunar free return trajectory without refuelling. This was shown in 2018 for the @dearMoon mission and not contradicted.

    A lunar landing with a relaunch back to Earth takes 1 refuelling in a high elliptical orbit. More refuelling gets you more return cargo.

    Mars with max payload and a fast Mars trajectory takes several refuellings, or an orbital depot that's been pre-filled.

    SpaceX already has the only flight-proven US spacecraft-2-spacecraft docking system; developed for Crew Dragon, and tested during DM-1.

    SpaceX and NASA are developing the detachable propellant tank fittings at the bottom of Starship. On Earth these will convey launch propellants from the Super Heavy booster to Starship.

    In orbit, a Starship Tanker and Crew/Cargo Starship will dock tail-to-tail, then an ullage burn will create a micro-G acceleration which will move the propellants into the Crew/Cargo Starship. Then they disconnect.

    Space News has a write-up about the expansion to 30,000 StarLink satellites.

    The first launch of operational satellites (the first was a test group) comes later this month or early November. More this year, then about 24 StarLink launches in 2020.

    https://spacenews.com/spacex-submits...nk-satellites/

    SpaceX submits paperwork for 30,000 more Starlink satellites

    WASHINGTON SpaceX has asked the International Telecommunication Union to arrange spectrum for 30,000 additional Starlink satellites.*

    SpaceX, which is already planning the worlds largest low-Earth-orbit broadband constellation by far, filed paperwork in recent weeks for up to 30,000 additional Starlink satellites on top of the 12,000 already approved by the U.S. Federal Communications Commission.
    >
    Here is SpaceXs full statement:

    "As demand escalates for fast, reliable internet around the world, especially for those where connectivity is non-existent, too expensive or unreliable, SpaceX is taking steps to responsibly scale Starlinks total network capacity and data density to meet the growth in users anticipated needs."

    I have read that NASA faced major political pressure when they tried to push in-space refueling experiments, because refueling could make certain rockets less important, which in turn would affect jobs in certain locations.

    One advantage for SpaceX is that they are dealing with methane, which should be less technically challenging than hydrogen, the focus of NASA’s previous work.

    Alabama makes Delta IV cores though. And my state would actually have made more money that way.

    I seem to remember a blurb from AV week talking about the need for dozens of depot flights
    http://www.spacesafetymagazine.com/s...t-fuel-depots/
    http://www.thespacereview.com/article/1447/1

    Shuttle-derived heavy lift simplified the way to the moon--and meant you didn't have to fly so many EELVs--which hurt the EELV lobby...and those guys are the one moaning about refueling now.

    That was hydrogen, mind you--which is quick to boil off.

    Starship uses less finicky Methalox, and it uses HLLVs both--so you can refuel right away--as oppposed to having EELV launched depots quietly outgassing LH2--leading to more EELV launches etc.

    The SD-HLLV folks weren't the bad guys. These are EELV hucksters trying to re-write history.

    Did I mention SpaceX and their contractors are working at break neck speed, often 3 shifts?

    Julia Bergeron @julia_bergeron (Teslarati)

    Starship facilities update! It appears the new landing pad is just about finished at 39A. The Phase One Starship pad should be added once the concrete cures. So, basically any day now we should see vertical progress. #Starship #39A
    |
    The new Robert's Road location is seeing some action as well. A mysterious bulkhead can be seen and the road leading in is being leveled. That will have to be ready for MK2 to be delivered as I suspect this will be where it will be prepped ahead of launch. #Starship

    SpaceX's Principal Mars Development Engineer Paul Wooster spoke at the Mars Society.

    One render he showed reveals a significant change to the cargo Starship.

    It now has two clamshell doors; the upper door swings up while the lower door flips out flat to become a large elevator platform which runs to the ground. This exposes 4 cargo decks. All of this is on the leeward side during re-entry..

    I wouldn't call this "a change to the cargo Starship"...it's a new concept for a Starship specialized for surface cargo. There's likely to be several types.

    The original Cargo vehicle had the same ~3x3 meter door as the Crew vehicle with different internal outfitting and a jib crane to lower the goods or crew in a basket. Clearly sub-optimal. This switch to a clamshell door & integrated elevator could only be a replacement for the original Cargo.

    Tanker and Chomper are different builds entirely.
