    RELEASE 19-063

    NASA Announces US Industry Partnerships to Advance Moon, Mars Technology


    As NASA prepares to land humans on the Moon by 2024 with the Artemis program, commercial companies are developing new technologies, working toward space ventures of their own, and looking to NASA for assistance. NASA has selected 10 U.S. companies for 19 partnerships to mature industry-developed space technologies and help maintain American leadership in space.

    NASA centers will partner with the companies, which range from small businesses with fewer than a dozen employees to large aerospace organizations, to provide expertise, facilities, hardware and software at no cost. The partnerships will advance the commercial space sector and help bring new capabilities to market that could benefit future NASA missions.

    LC-39A EIS; pad mods for Starship/Super Heavy

    Just Read the Instructions sets sail for the East Coast August 15.

    Wow....

    Chris B - NSF @NASASpaceflight

    "Draft Environmental Assessment for the SpaceX Starship and Super Heavy Launch Vehicle at Kennedy Space Center (KSC) - https://netspublic.grc.nasa.gov/main...X_Starship.pdf - heck of a long read, but as we reported http://(https://www.nasaspaceflight....nches-pad-39a/ ), Starship Pad 'off ramp' on 39A. "

    "SpaceX plans to launch the Starship/Super Heavy up to 24 times per year from LC-39A. A static fire test would be conducted on each stage prior to each launch."

    Looks like Super Heavy lands on an ASDS.

    Initial Starship landings at LZ-1

    Initial Super Heavy landings on ASDS.

    Initial vertical integration by mobile crane, with a permanent crane coming later.

    Launches from a ~30m elevated platform with a cooled flame diverter instead of a trench.

    Starship propellant mass has has grown from 1,100 metric tonnes to 1,500 metric tonnes (per EIS.)

    EIS PDF...

    2.1 Proposed Action

    A fully reusable rocket system consisting of two parts, Starship and Super Heavy booster, is being developed by SpaceX for crewed and uncrewed missions to take humans and cargo to Earth orbit and beyond, including to the Moon and Mars. SpaceX plans to launch thevStarship/Super Heavy up to 24 times per year from LC-39A. A static fire test would be conducted on each stage prior to each launch. The launch vehicle is comprised of two stages: Super Heavy and Starship. Super Heavy is the first stage (booster), and Starship (ship) is the second stage. The integrated vehicle would be 118 m in height with the ship being 55 m in length and 9 m in diameter. The top of the fully integrated rocket once installed on the launch mount would stand approximately 150 m above ground level (Figure 2-1). As mentioned, both stages would be reusable with any potential processing actions taking place at SpaceX facilities. The booster is expected to have minimal post flight refurbishment requirements; however, it may require periodic maintenance and upgrades. Unlike Falcon, there would be no separable fairings or parachutes in this reusable system. The booster would be powered by 31 Raptor engines and Starship would be powered by seven Raptor engines. The Raptor engine was recently developed and is currently in Texas undergoing tests.

    Starship/Super Heavy maximum lift-off mass is approximately 5,000 metric tons (MT), with a lift-off thrust of up to 62 meganewtons (MN) (13.9 million lbs). The booster would hold up to 3,500 MT of propellant and Starship would hold up to 1,500 MT of propellant. The propellant is composed of liquid oxygen (LOX) and liquid methane in a 3.6:1 mass ratio. Each Raptor engine would produce 1.7 to 2.0 MN (0.3 to 0.4 million lbs) of thrust. The 31 booster engines would cut off at an altitude of approximately 70 km and the two stages would separate. Shortly thereafter, at an altitude of approximately 80 km, the Starship engines would start up and burn to the desired orbit location. Additional operational details are provided below. All vehicle specifications, propellant, and mission data would be provided to NASA to ensure the Proposed Action meets NASA safety requirements.

    Something I was thinking about. I've often been a fan of wet stage concepts--and I wonder if Starship might be best used in this wise.

    Now, I understand the legs are to be crushable--that would seem to point towards a one-way mission--unless repairs can be made.

    I can see Starship landing in a crater--and the crater lined with mirrors to shine on Starship itself--as it once again becomes a water tower--which is how it is made after all. Lunar water goes inside the tankage and is heated for power.

    Smaller landers and such return crews, while starship hulls are left behind.

    In case re-entry problems occur--Starship can then still have a use.

    That's an even worse idea than repurposing propellant tanks as habitat structures. Starship is neither a water boiler nor a solar thermal receiver. It doesn't even particularly resemble these things, and certainly wouldn't perform well in their place.

    Reaching the moon requires multiple refueling operations in orbit using other Starships as tankers. Starship isn't going to the lunar surface until SpaceX has it flying, returning intact, and reflying with a short turnaround time. When you do have Starships landing on the moon, you will be able to construct far better solar thermal systems with components actually designed to be part of such systems shipped to the moon as Starship cargo. The best thing to do with the Starship will then be to send it back to bring another cargo load.

    Yes. The Super Heavy first stage is a separate build - and simpler.
    The first SH builds should begin soon after the Starships are stacked and moved to their staging areas.

    SpaceX decided to tackle the harder build first given the Starship can fly by itself, expediting tests.

    I'm surprised Howard Huges or somebody didn't try this before. Then too, Truax never had any money--any reach...Maybe if that first Snake River jump had worked...

    Wow....

    Look out SmallSat launchers....a small satellite bus service

    https://www.spacex.com/smallsat

    SMALLSAT RIDESHARE PROGRAM

    DEDICATED AFFORDABLE RIDESHARE TO SUN SYNCHRONOUS ORBIT


    DEDICATED ESPA CLASS MISSIONS AS LOW AS $2.25M

    SpaceX's SmallSat Rideshare Program will provide small satellite operators with regularly scheduled, dedicated Falcon 9 rideshare missions to SSO for ESPA class payloads for as low as $2.25M per mission, which includes up to 150 kg of payload mass.

    Unlike traditional rideshare opportunities, these missions will not be dependent on a primary. These missions will be pre-scheduled and will not be held up by delays with co-passengers.

    For payloads who run into development or production challenges leading up to launch, SpaceX will allow them to apply 100% of monies paid towards the cost of rebooking on a subsequent mission (rebooking fees may apply).

    Huge updates coming, but still embargoed. Aug 24's gonna be interesting...

    https://twitter.com/elonmusk/status/1158590084280549376

    Great progress by Starship Cape team. Started several months behind, but catching up fast. This will be a super fun race to orbit, moon & Mars!
    >
    Race to orbit by both teams, although a success by both in close proximity would be amazing & each would count as a win
    >
    Vandenberg is great for polar orbits. Will still play an important role long-term, but 80%+ will be eastward.

    I assume that, at the moment, they only attempt to catch 1 fairing half anyway? But it's the second time in a row they caught one, so they might be onto something there. If it would take 2 ships to catch 'em all, it becomes a viable option once they know the system works.

    They're catching one, splashing and retrieving one. The splashed one gets examined to see if it's water damaged, informing if they'll need to continue using Ms Tree. So far splashed fairings are looking pretty good.

    Fairing reuse will be tested on the numerous upcoming StarLink launches. At $6m a pair it could really lower costs.

    Given that they also need to send out a ship to get the splashed one out of the water anyway, what money would they gain with splashing-and-fishing versus net catching? Does the splashed one use a cheaper parachute or something? Once you have converted the ship, I don't see how using Ms Tree itself would be significantly more expensive than any regular ship (it's not a boat, mr Musk!)

    Leasing the ship is cheaper than a lost fairing, and the parachute guidance system differences are marginal since SpaceX builds most of their own electronics. When they say "vertically integrated" they really mean it.

    To fill in what Everyday Astronaut started,

    StarHopper 200m test flight.

    If successful, StarHopper's useful parts are removed and it becomes a trophy like Grasshopper.

    Starship Mk-1 goes to the pad, preparing for a 3-engined series of hops & jumps

    yes, but that still doesn't explain why they'd in the future potentially prefer to let them land in the water and drag them onto a ship, rather than in a dry net on the ship directly. I don't see any financial reason why they would NOT want to use Ms Tree if the net method works, even when the water damage from splash&catch retrievals would turn out to be minimal. the only thing I could see was that you'd potentially need two Ms Trees to catch both halves, while you could splash&catch both halves with only one ship.

    I don't think there's much left of Grasshopper, as it exploded quite convincingly.

    Grasshopper completed it's tests successfully, and now resides in an honored place at the McGregpr TX test center.

    It's successor, F9R Dev-1, had a mid-flight engine sensor fault and self destructed.
