Are the Orion plans finalized yet, or is it still a work in progress?  Also, are there plans to record the construction of Orion with video?

It hasn't reached PDR yet

Will LIDS support SSPTS since it seems that Orion will not need it owing to the fact that it has its own solar panels?  And if not, will SSPTS need to be removed post-shuttle for the LIDS-APAS adapter or at the very least some parts on PMA?

LIDS will contain umbilicals which will be capable of passing TBD watts of power.  But, it's my understanding that those requirements are being driven by the lunar mission, not by station.

Has there been anything released further by NASA or Lockheed Martin on the interior design of Orion?  I'm interested in the the crew seating layout, storage lockers location, etc.

Right now it looks like there are 2 parallel but different systems.  One is the LPTU (lunar or lander power transfer unit) and the SPTU (station power transfer unit).  They want the SPTU because a study said that the panels would not always be able to get enough sunlight to keep the batteries in orion charged up for an emergency departure.

Will there be a MSS for Ares similer to the Saturn/ Apollo MSS?

They are trying to avoid having one by having the hypers loaded on the spacecraft before stacking and rolling out only a week before launch.  Also the LUT will have access where needed

Thanks for the answer.  I have another that is related to LIDS.  Can a craft using LIDS be docked using a robotic device (ala SSRMS)?  I know APAS cannot, however with the need for less force to engage I am not sure for LIDS.

Probably yes, IMO.

The LIDS will have that plate actuated in 6 degrees of freedom - that is translation left, right and forward; plus rotation roll, pitch and yaw -for a smooth, low impact with the target's plate. All this followed by catchers engaged by electro-magnets.

So LIDS should easily work in a SSRMS-type slow berthing - but this would be a waste of talent, no ?

This document:

http://www.nasa.gov/pdf/258193main_06_Section_4.pdf

at page 29 :

SSP Asset or Facility : T-38s
Description: These aircraft are for astronaut transport between NASA facilities and for training purposes.
Disposition: This property has not been identified for use by new programs.


What aircraft shall replace, if any, the iconic T-38 ?

NASA will keep the T-38's.  They were there before the shuttle.  CxP will pick them up

Will Orion capsule have touchscreen or usual screen with usual buttons?

There is a thread on the Orion cockpit

I'll join in to this with a quick question -- it may already have been discussed but if so, I've missed it.

Based on the latest rendering's I've seen, Orion's SM has got thrusters for pitch and yaw and forward translation (or, I suppose, pitch/yaw backup).  But I can't see anything for roll control.  Am I just missing something or is there cleverness at work?

Cleverness.  It has 6 degrees of motion  (including up and down side to side and fore and aft).  There is a thread explaining it.  I try to find it;.

Ok, here is a diagram of the SM, I couldn't find the thread, so I recreated it.

I eliminated the redundant thrusters and only had a single fore and aft on each cluster.   The clusters are located 45 degrees off the planes of  each major axis.  There are two more clusters mirrored on the other side, which I will refer to the "other side of the page"

I will list the 6 degrees of freedom and the associated thrusters that are need to produce a movement or rotation.

pitch down - 2 & 4 and 1 &3 on the other side of the page

yaw right - 2 & 3 and  1 & 4 on the other side of the page

roll right - 1 & 2 and  1 & 2 on the other side of the page

Forward translation - 1 & 4 and  1 & 4 on the other side of the page

right translation - 1 & 2 and  3 & 4 on the other side of the page

down  translation - 1 & 2 and  3 & 4

Mentally, I can only get these to work if the other side of the page is rotated 180 about the fore-aft "90" line (which places the bottom 1-2 on the starboard side and bottom 3-4 port) rather than mirroring (which places bottom 1-2 on the port side and bottom 3-4 starboard).

Well, all except this one. Did you mean "2 & 4"? I don't see how two forward-facing thrusters and two aft-facing thrusters can produce a net forward translation.

I think I'm going to have to build myself a demo Orion out of Lego and try to figure this out...
