    Constellation Space Program - Three Part Challenge



    Constellation Space Program - Three Part Challenge

    It's January 2008 and the first prototype of the Orion spacecraft has just been unpacked. This new spacecraft can carry up to 6 crew and is designed for missions to the ISS, lunar orbital and deep space missions. There is a team of engineers working on a new lifter family, called Ares, based on technology developed for the retiring Space Shuttle program. Another team is developing the Altair advanced lunar lander, while another group is off in the corner talking about landing on "the red planet".

    These three new spacecraft, all developed using technology from the Space Shuttle and Apollo space programs, make up the Constellation space program. Expectations are high for this revival of deep space exploration, and there is no sign on the horizon of any kind of global financial meltdown that might impinge upon the development of the Constellation space program, in any way, whatsoever.

    The Constellation space program is divided into three main mission profiles:
    1. Missions to the orbiting space station to replenish supplies and deliver crew
    2. Lunar orbital/landing missions
    3. Mars flyby/landing missions

    NEW: There is a new rules sub-set for anyone wishing to develop only the Mars/Duna spacecraft and carry out the "red planet" landing missions. See "Mars Direct Challenge" below. All previously submitted entries already qualify.




    This challenge puts you in charge of implementing the visions of the Constellation space program. You will need to develop a space launch system, a command module for at least 4 crew, and a new lander program. Once ready, you will then plan and execute a series of missions ranging from un-Kerballed ballistic tests to landings on the Mun and Duna. Three kinds of points are awarded: Design Points, Mission Points and Science Points.

    Design points are awarded based on design principles which resemble the Constellation hardware and for completion of various stages in the design process. Mission points are awarded for carrying out specific mission profile steps designed to push the limits of the Constellation space hardware, and your mission execution skills. Unless otherwise specified, all points only count once.

    As several of the Mission Points include rendezvous and docking with an orbiting space station, there is a 'persistent' file provided below which includes a simple space station in a 120 km orbit and features two of all three types of docking ports. If you choose to launch/use your own space station, it must be in an orbit with Pe/Ap both above 120km. It should also have at least 4 Kerbals on board.

    Challenge Rules:
    • Optional: New SAVE files with simple space station at 120km, 2 of each docking port and four Kerbals on board (KSP v 0.23.5):
      1. Save-game directory: https://www.dropbox.com/s/evmp0jbtbdsa597/CCR.zip
      2. Just the persistent file:https://www.dropbox.com/s/cx4jyo93r1...persistent.sfs

    • Stock or mod parts permitted.
    • Other than SAS, no flight assists. Fly it yourself without mods that aid in flight/landing.
    • Low orbit is considered to be minimum 75km x 75km.
    • Boilerplate test launches do not need to use an actual capsule but do need to have similar mass to a final capsule. For example, the boilerplate capsule/EDS should have the same amount of fuel that the the EDS and Orion service module carry, a probe core, and either re-enter or be able to de-orbit itself.
    • Un-Kerballed test launches should use the final, "announced" hardware and be robotically controlled to mission completion.
    • Once you develop your space hardware, post it on this this thread as an "announcement" from your space program. The hardware should remain unchanged throughout the challenge steps after your announcement.
    • You may announce hardware separately as they are developed, but you cannot claim points on a mission step unless you have already posted about the hardware used in that mission in another post. In other words, you can complete and earn points for each phase of the space program (R&D, low orbit, Mun, Duna) separately before the next phase is developed and "announced".
    • The leaderboard will be updated as posts are submitted, so feel free to announce hardware and post mission steps as they are completed. The intent is to treat each challenge entry like a developing space program and to encourage discussion as each space program makes steps forward.
    • For space station missions, the space station must be in a circular orbit of at least 120km.
    • Where "pressurized" is stated, this means any command pod and not the open-air command seat, although seats may be present in addition to the command pod(s).
    • Science points require at least one Science part, one communication part, and a probecore and remains powered.




    Challenge Summary:
    For a minimum of four crew, develop:
    • Space capsule with separate Command and Service modules which will jettison the Service module before re-entry (Orion)
    • Two-stage to orbit lifter for the crew capsule (Ares I)
    • Two-stage to orbit (first stage plus an EDS) for the Orion/Altair/Duna spacecraft (Ares V)
    • Munar lander (Altair) and Duna lander
    • Duna Surface Return Vehicle
    • Perform science in space, on Duna and on the Mun


    Using only the hardware developed above, perform:
    • Missions to an orbiting space station
    • Munar landing and return using EOR mission profile
    • Duna landing and return using separate Duna lander and Duna ascent vehicle (the lander stays on Duna as-is)

    Too much text. And predefined craft name...

    Can I have some common minded simple explanation?

    Hi Death Engineering

    sadly I don't have the time right now to do a full entry into your challenge (IB student...), but I find the constellation concepts really interesting
    I have created some replica craft from these, such as the Ares I and the Orion Spacecraft (with a crew of three only tho). I'm sort of sad that the Obama Administration killed Constellation, but at least there's still SLS (which I'm in the process of recreating in KSP as well). However, people have done some calculations and think that SLS is too expensive and will never actually fly
    So I guess we'll have to rely on SpaceX (or the Chinese...I live in China XD) for these things in the future.

    That said, I would still like to post my craft here, just to start up the challenge and to give others inspiration.

    So here's my Ares I:



    Sorry, there are no more screenshots as of now, but if you like, I'll fly it again and take screenshots of the whole flight, LES and landing of Orion, etc... (of course not it you don't want me to spam you challenge thread with non-entry posts )

    I can't find any more screenshots right now, sry. BTW, here's my SLS Prototype on the launchpad. This creature is also carrying my Orion spacecraft, a lander, and should be capable of doing single-launch and return trips to Mun, Minmus, Duna, Dres, Ike, Gilly(duh) and maybe Moho?:



    So if you'd like, I'll post pictures of the entire Ares I flight, just as an inspiration (uses ONLY SRBs on first stage! and the second stage is powered by an engine similar to the real-life J-2X) BTW, both my Ares I and my SLS use KW Rocketry parts (SLS also B9 panels cuz they're white and aesthetics count)

    Ikr...
    But be fair and considerate, since the OP probably spent several hours thinking it all through and writing that post

    The spacecraft are named in the challenge as they were in the real Constellation program for konsistency and klarity. For your own space program, call them whatever you want.

    What's the word on that persistence file, Death Engineering?

    Already did my first test of an idea for the Orion - not a proper boilerplate test, just a proof of concept of one of the features I considered when I first read about this challenge. As much as it pains me, I might have to join this one too...
    My first account was splashed in the Great Coffee Spill of 2013.

    Kerbin 1 Space Station

    The station in these files is on a nearly equatorial orbit at 120km. There are three Sr. docking ports and two of each of the smaller docking ports. There are also four Kerbals on board waiting for a replacement crew. Toggle the solar panels with action group "8".

    Using the "Kerbin 1" station is not a requirement. If you choose to use your own station, feel free as long as it is at least 120km minimum altitude.

    Just the persistent file: https://www.dropbox.com/s/cx4jyo93r1...persistent.sfs

    edit: This station has 62 parts with a 18t mass
