    I'm taking a break from tilting my head back and forth like a confused dog to post about the strange happenings in Boca Chica, Texas. Which has gone from a place where the most exciting thing happening was soil settling under a large mound of dirt at the site of a future launch pad, to buzzing with activity. But lately the main attention grabber has been the large grey and silvery shiny thing that's being built.

    To outside observers this is roughly how the situation has progressed:
    -I guess they're building a water tower?
    -It looks like they're building a nose cone, but no way it's a rocket, no one builds rockets outside. Out of what appears to be steel of all things.
    -Stainless steel???
    -Ok I guess it's some kind of mockup test article, maybe to test how certain parts fit? Boy some of those panels look rough.
    -...now it has 3 engine bells on the bottom of it...double engine bells that look like the real thing.


    And as I was thinking about making this post Scott Manley put out a video and I think he covers it quite well.



    These are extra exciting times if you're a big fan of shiny silvery rocket ships from 1950's sci-fi!

    Maybe it'll be a dummy load for the BFR booster? You'd want something that simulated the loaded weight; (relatively) cheap steel could make up for it being hollow. Most dummy weights can be simple weights because they're under a fairing, so having real(ish) aerodynamics probably helps, too. If they get it all the way to the ship's orbit circularization it'll burn up coming back down. No sense in building heat shielding on a ship that will probably explode on the way up.

    I'd imagine getting real world data on how the new engines behave through various flight envelopes (probably low speed but who knows at this point) is the number one priority, followed closely by verifying the control software doesn't produce any strange results flying something as large as this hopper is going to be. Maybe that's why they went with three engines when one could have sufficed, triple the engines and you get more data back during the flight and when you take them apart to verify everything is performing within expectations.

    Plus, as Scott mentions in the video, playing with engine-out scenarios, different "landing" profiles (1 engine vs 3 at low throttle, etc)

    The Raptor is supposed to have an even larger throttle range than the Merlin, which is already world-class

    A little more information about the Starship Hopper currently being constructed in a tent in Boca Chica





    I think it being a stainless steel construction, etc. allows them to get away with building this low-altitude test article outside, which is actually kinda neat for the future of spaceflight - if they do intend for these vehicles to eventually be reentering the earth's atmosphere 100s of time, they'll have to get used to sitting outside in all sorts of weather! :surprised:

    I was wondering when there’ll be nice high resolution pictures from the fly-by of Ultima Thule and saw that the transfer speed is apparently 1-2 kb/s and it’ll take like 10 months or something for the whole data package.

    They did 2 failsafe picture downloads prior to closest approach and plan 3 "new york times" hype photo downlinks in the 2 days after. Those won't be the highest resolution pictures they'll eventually get get, but as you say, it's important to get them out fast to showcase the success of the mission. All the science data and better pictures will come over the next year.

    They'll need more than just stainless steel. It'll still need a coating and regular maintenance for the outer layer to prevent corrosion, as well as inspection of the joins between the skin and the primary structure. Stainless is only corrosion resistant, and the combination of heat, direct sunlight, and saltwater, care not for your resistance. I suspect that that's why NASA built maintenance buildings for their rockets. Protection from the elements as well as walkways that make inspection easier.

    Oh, definitely - and I suspect that if this test article sees any long-term use, it'll have an indoor home to retreat into for exactly those purposes :)

    I just think it's neat that they can slap together this shell of the vehicle outside in a tent, though building things in tents is hardly revolutionary for a company headed by Elon Musk >_>

    They wish they had 1-2kb/s - the transfer rate's about 500b/s on a good day.

    It's currently not a good day - the probe's right behind the sun right now, and has been for a few days. The downloads are supposed to resume as soon as a gigantic screaming radio source isn't parked right in the line of sight, which should be later this week.

    A few months ago, a few US publications seemed to speculate about the shuttering of Baikonur Comsodrome, with the operation of the civilian facility at Vostochnny Cosmodrome, and the closing of one of the launch facilities. That might still happen, and one of the launch sites--the famous "Gagarin's Start"--will go unused with the planned replacement of Soyuz-FG by Soyuz-2 (which can be launched from Vostochnny, Plesetsky, and the former French Guiana). However, Baikonur is still planning 19 launches in 2019 (more than double the slow year of 2018, with only 9), with the first Soyuz mission in March.

    In September, with Soyuz MS-14, the manned version of Soyuz 2.1 will be launched in preparation for the first passenger missions in this variant.

    Now that it's no longer blighted by the sun, apparently the New Horizons team have Done Something with the spacecraft, resulting in the downlink to Earth from it operating at 1.58kb/s instead of less than a third of that. So data coming in again and doing so much more 'quickly.'
