K1SS, LLC. Orbital operations division.
Suite #27, 2920 Zoo Drive, San Diego, 92101 CA


Re: Mission #8

Dear Mr. Castor,

I'm happy to inform you that K1SS LLC. is able to undertake mission #8.

Our analysis of the mission shows that delta-v requirements for the tug are about 600m/s in total:

- circularization of 250km parking orbit: ~200m/s
- interception burn: ~140m/s
- velocity matching with OFSS: ~250m/s

Based on this, we believe that the smaller DM tug is a more fitting tool for this mission than the Smerch tug. Our analysis shows that use of Smerch tug, in addition to raising costs, is actually detrimental to the mission, as the heavy Smerch tug is very difficult to maneuver. For this reason, we request changing the mission hardware to use DM tug instead of Smerch tug.

Since the OFSS Consortium has already purchased the Smersh tug, we will cover the costs of purchasing the extra DM tug, if the OFSS Consortium agrees to sell us Smerch at a reduced price.

Sincerely,
Koko G. Orilla, Ph. D.
Division Manager

K1SS LLC. is an equal opportunity employer.

Artlav and Athena, I'm sorry for the delay but a few technical problems have cropped up. As soon as they are resolved, I'll put up the new package.

kamaz, thanks for taking up mission 8.

Thanks to jedidia, all the problems have been solved. I'm sorry to have to do this again, but:

Artlav, please confirm you will be available for the fourth mission :

Date of launch : 21 June (Saturday)
Date of mission completion : 27 June (Friday)

Athena, please confirm you will be acting backup.

We'll also need a backup for #10, I'll be in Norway from June 29 to July 26 and unable to fly during this time.

No problem, Astrosammy. Happy to back up.

Note: Artlav and Athena, the fourth mission has been released. Download the package from the first page.

Date of launch of fourth mission: June 22 (Sunday)
Date of completion of mission: June 27 (Friday)

Flight Notes:

In this mission, the XR2 will deliver the CMG to the station. In addition, the cargo bay also has extra scram and main fuel.

The XR2 is to rendezvous and dock with the APAS port of the station. The station must be integrated shortly afterwards. Do not attempt to enter the station, as lifesupport capabilities are not present. Using the battery power of the command module, open up the doors of the airdock to expose the inner dock.

The XR2 then has to undock, following which an EVA takes place. The prime objective of the EVA would be to grapple the CMG in the XR2 payload bay, and to attach it to the inner dock (of the airdock module).

The XR2 has to redock once again with the station. The airdock cover is closed once again. Now switch focus to the CMG vessel, set pitch=0; roll=0; yaw=0; and press 3 to activate attitude control. Wait for the station's attitude to stabilize.

Next, the station's orbit has to be corrected. For this, adjust the values of pitch, yaw and roll in the CMG till the XR2 is pointing in the right direction. After corrections:

Orbital altitude = 800 km (± 10 km)
Inclination = 64° (± 0.4°)


After all mission objectives are done, keep the XR2 docked to the station and post the final scenario. The XR2 landing scenario will be given to you once the fifth mission is complete.

If you have any doubts with the above mentioned steps, please don't hesitate to ask.

Hi there.
I ran into some time management issues, will be away from computers for a couple of days, and won't be able to finish the flight and the story until sunday at the earliest.

So, no need to wonder at the silence. All is going well. :)

Already finished the actual flight.
It's the write-up that takes time.
I'll post the final scenario now, to allow the next flight to go.

Tried to post two chapters in a row, but the forum clumped them into one post, making a mess.
I'll post the other one once someone else writes, or the time limit expires.

Then there should be a short reboost chapter, and i'll see about landing when it gets to it.

Concerning the flight:
-CMG ended up attached at a weird angle. Not sure if ti's supposed to be so.
-Getting to 800km x 800km within +-10km is not possible, since the nonspherical gravity skews it much more over the course.

Just to let you know Castor, you only have to make a scenario containing the station in orbit and the general date I'm supposed to launch on. I'll handle the M-II payload integration (and custom payload fairing), launch azimuth, and exact launch time.

In which case, I will post a general scenario here on this thread; and following payload integration, you will have to post a pre-launch scenario on this thread so that I can include it in the package.

Concerning the flight:
-CMG ended up attached at a weird angle. Not sure if ti's supposed to be so.
Yeah, it's a problem with the docking port placement, nothing to worry.


-Getting to 800km x 800km within +-10km is not possible, since the nonspherical gravity skews it much more over the course.
Try to keep the station in as reasonable an orbit as possible.

Alright.

Meanwhile, can someone post something in the write-up thread, so i could post the next chapter without it clumping up with the previous?

After vehicle integration, please post the launch scenario on this thread. If any config files have been added or modified, post that also.

P.S. The station's attitude is being maintained by the CMG. If there is a need to time warp more than 10x, turn off the CMG first (switch focus to the CMG and press 3).

Did a practice run (with non-spherical gravity turned on), starting with a scenario with these conditions:
-the ISS (with CMG) in a 800 x 800 km orbit
-the Tranzit in a 800 x 200 km orbit, planes already aligned with the ISS

I managed to rendezvous and dock with the station using 206 m/s of delta-v.

Sync orbits with non-spherical gravity isn't as bad as I thought it was going to be. All I needed were small corrections to the DTmin whenever I passed the intercept point.
I'm doing a practice run with the actual launch scenario, and now I'm having problems with the non-spherical gravity. Due to the constantly fluctuating orbits, the DTmin as well as the intercept point keep fluctuating drastically. In the Align Planes MFD, the Relative Inclination shifts an entire 0.1 degrees over time.

This is really annoying and I'm not sure how people manage to do it. Is there a better way? Do you really need constant corrections for the RInc?

Also, can you please tell me where I'm supposed to dock?

Due to the constantly fluctuating orbits, the DTmin as well as the intercept point keep fluctuating drastically.
Set a manual axis for the Sync Orbit to keep it cleaner, and work to get your orbit aligned as much as possible (push your periapsis around to match the target, etc, so your perturbations are similar to the OFSS).

It just gives a new level of respect for the calculations to do this stuff for real. So many runs up to the ISS look mundane and routine now (even for the little privateer companies), but it's far from that!
