What in your opinion is the single most difficult task presented thus far in the 22 SSM 2007 missions made available thus far.
I will nominate the TPAD capture of Solar Max during STS 41-C. It is one of only two elements where you must dock to an object without being able to look through the centerline to your target. STS-51A is the other, but its far easier to place the end of the "stinger" and you have a much larger target. In addition you have a tangentially moving target with Solar Max as the satellite spins.
Anyone think anything else is tougher?
Some nominations...
Berthing Destiny to Unity (STS-98)
Berthing SSRMS Pallet To Destiny (STS-100)
Dock Zarya To Unity (STS-88)
Capture LACROSS 1 Without Any Radar Rate And Range Guidance (STS-27)
Capture Atlantis At Odd RMS Angle (STS-401)
-
Finding the EVA trigger points in many of the EVA missions.
-
all those moving targets (or EVA triggers) have never given me as much head-ache as the moving the PMA on and off the Z1 Truss on STS-98.
IMHO, those two tasks are the most challenging of all..
-
I agree with Uri_ba: I was very lucky, and solved the situations in few minutes, but my impression was of extreme difficulty.
-
I have to say that STS-100 was pretty hard, and the second would be STS-103, the most difficult EVA I think on the game.
-
I should also have to agree with Uri, I just finished STS-98, and it took me a lonnng time to figure out how to maneuver the PMA
-

+1000% :-\ :(
-
For me, the hardest mission ever is STS27 :) And that will be more harder if they add the Tile inspection !
-
STS-98, Hands down. ::)
-
haaaa, yes, 98 ... I forgot that one ! You're right !
-
By far STS 1 - just kidding. ;D
I think STS 27 was pretty tough but STS 88 was my "problem child" mission that took me the longest to complete. I think i did 5 other missions before fully completing STS 88.
-
Uri, I'm just doing STS-98 now, moving the PMA2 was a nightmare, I think I would of clipped something when I was moving it. IMHO would be a lot easier with all of the RMS modes, hint, PL ;)
Also, did the Astronaut helmet camera's plus verbal commands help with postioning PMA2, as the cameras were blocked most of the time?
-
Here's a nice article about STS-98 and Marsha Ivins who relocated the PMA 2 and what technique she used to do it:
http://spaceflight.nasa.gov/shuttle/archives/sts-98/crew/intivins.html
They used the same technique (camera/mirror) on STS-130 now, when PMA 3 was relocated.

Sorry but I do not like that video. It is very disturbing in having the knowledge it could happen
-
This is highly illogic.
First, which forces would rip these parts of the shuttle (and let the ISS be intact to film from within)?
Second, all these ripped of parts flying in a constant distance to the station?

I just meant seeing the Shuttle like that. It could happen. Not likely but it makes me think of Columbia and Challenger
-
::) well, I hope that you never die in SSM2007 ... ;)
Of course we hope that it will never happen but it's a simple special effect, like in a lot of movie (Space cowboy etc...)
-
the hardest part of ssm is landing. I have still not landed at all in any of the missions. Completed the mission but can't land.

No, we do NOT plan any tragedies in SSM and we hope that life does not prepare some for us before the STS is retired.

I think it was a joke ;)
Way going off topic...
I had a very close call once when my wife threw a rather hefty psychology book, when she wanted me to take out the trash earlier in the day.
Going back on Topic:
On STS-98, I've redone the mission. Rather then doing a quick repositioning of the PMA, I did it slowly and cautiously, only making micro movements. First getting the PMA away from unity module along the long axis of the shuttle. Then spent a good 30min translating it upwards away from the shuttle, until the required height. Finally translating it towards the temporary storage location on the Truss. All this whilst keeping the PMA in the correct attitude. Overall, it took 3, maybe 4 hours, whilst the 'quick way' only took 45mins.
A lot of repect to the RMS operators, the training they must go through, just doing it correctly must take days. Then there is the training for when it goes wrong, which there must be weeks if not months.

If you have any flight sim experience, it is not much different. Really learn the HUD symbology and the SPEC 50 Horiz Sit display and how to interpret it in the commanders handbook. This also teaches you about energy management which is critical in a craft with no engines. Keep practising just the landing section of missions to gain experience. It's all about the practice! ;)
-
I agree practice, practice, and practice.

I used to be like that =p Then I took a month or two break from SSM (I had some bad withdrawals @_@) and when I came back, I got it on my first try >_> My land-crash ratio is getting much better <_<
-
Make a really good approach, then save the scenario about 5,000 Feet AGL. Then you can practice the landing over and over again much more quickly.

That's what I did...works well. My landing attempts are improving.
-
I agree with the others.
I think, STS-98 was the hardest I have completed.
-
As for landing I had a hard time the first 2 missions. (six attempts on the first and three on the second) After those I've nailed the landing on the other 2 that I've completed. A joystick really makes a difference. Once you have a successful landing, it will get much easier. You know what to expect on the turns and at what angle you should come in on. I only use roll and pitch and it works fine for me.
-
STS 98 (so far). I still haven't been able to grapple the PMA and move it back to Unity...... Got to take a break cause I'm not getting anything in the house done because of this sim! ;D

Hi. To me the most difficult task is on every ISS mission, is where I have to move the OBSS to the MPLM survey location. This problem occurred on STS-128 and 130, around half an orbit after docking. The end effector position never changes once I grapple to the OBSS, and the yellow arrow and the RMS attitude position seem to conflict. I tried moving the OBSS to the yellow position, and the attitude values don't match the ones on the message. When I ignored the arrow and I tried to use attitude P/Y/R for the attitude position the OBSS positions very far from the arrow, and this is what plagued me from finishing the mission successfully. I would want to see a video of that kind of operation, either real or on the sim, so that I can copy it and do it correctly.
