    3 G's isn't all that much actually. Remember, the crew has lived under 1 G the entire mission, so there's none of this Zero G to 3 G issue.

    Two hours at 3 G's?

    I calculated that the delta V of the main Trans Pluto Injection burn to be around 350,000 m/s. Since the SSTV has over 20,000,000 m/s of delta V when fully fueled, this should not be a problem. Limited to 3 G's however will make this burn last a good long time.

    Thanks.

    Next stop Saturn!

    Congrats on that mission! Over a year is more dedication than I have.

    Yup, but I'm not actually flying the mission, I'm just using the SSTV as the spacecraft in a story I actually wrote down back in 1990. The Mission to Titan will be a new story that I will make up as I fly it 'in real time'. And then there's the mission to Pluto scheduled for SSTV-02's maiden voyage.

    Sheesh. You've been doing this real time? Major kudos, man.

    Yup. But the mission has gotten to the slow part as there are 10's of days between milestones and not all that much to report. The mission to Saturn/Titan will be a little more interesting and then there's the mission to Pluto.

    Sure will, but it may be a while as I've been spending quite a bit of time trying to finish up the Lunar Station where the SSTV's are built. I just finished mission 147 last night. I need about 750 missions I figure to complete it.

    Could you post a picture of SSTV-02 once it is completed ?

    Actually, you should imagine what the Lunar Station will look like when it is completed. Imagine something that is SO BIG that it will take something like 750-1000 XR5 missions from Brighton Beach to bring up all the components.

    Thanks for the compliment.

    Answer to the question

    The SSTV has 17 forward Hyperthrust Engines and 2 reverse Hyperthrust Engines on it and fully loaded has a delta V budget of around 20 Mm/s. These engines are part of the IMS 1.0 RC 6.

    It has enough delta V for a 100 day flight trip from LEO to Pluto orbit, so a 100 day flight to Jupiter is pretty easy. The main reason for going so 'slow' is this is the 'first' mission for the Hypertrust Engines and so 60 standard nuclear thermal engines were included in the design as a backup although using those it only has about 6km/s of delta V. It needed to arrive at Jupiter slowly enough so that the NTEs would have enough delta V to slow it into a highly elliptical Jupiter Orbit from which it could be 'rescued'. Once the Hypertrust Engines have been proven reliable, the NTEs will probably be removed from the SSTV along with all the truss structure they are attached to. This will improve the performance of the SSTV quite a bit.

    With all 17 engines burning, the SSTV can produce about 5 G's of thrust fully loaded. That's why they are only using 2 to 4 during normal orbit adjustment burns. There are pictures of the SSTV on this site, see the "Orbiter Pictures" thread about 5-6 pages (or more) before the last one.

    The Emergency Transport Vehicle is a stripped down SSTV with much less cargo capacity and is unmanned. With the fuel load on it, it can go from LEO to Jupiter orbit in 15 days easily. I think it has about 10,000 Mm of delta V although I don't have a screen capture to back that up.

    Here are some pictures of the SSTV docked with the ISS to give you some idea of its size relative to something most Orbiter pilots have seen.

    Jeeez.. what is the ETV powered by, an outsize Orion drive? That's an awfully short transfer to Jupiter.
