First time posting to the forum, please forgive if I'm not doing this right. Also, apologies if this has been asked or addressed before. I did a search, but no joy.I used to occasionally read, and sometimes follow along with, the execute packages that NASA posted on the website for shuttle missions. I've never been able to find a source for the ones used specifically on the ISS. Is there anywhere online that I can find the ISS packages?ThanksGlenn
eriol - what are the chances of seeing those Word files on L2? I hear them mentioned occasionally, especially during the WPCs.
Does anyone knows where are the 5 Service Module Debris Panels that were scheduled to be installed on the small diameter segment (RO1) of Zvezda during the Russian EVA-30?
Quote from: CitabriaFlyer on 09/11/2011 02:55 pmHow would you deorbit the station with current assets?The original plan was to use a ATV for de-orbit. I haven't heard of a different plan even though ATV is probably going to stop after ATV-5.
How would you deorbit the station with current assets?
The ATV-3 the other day performed its first station re-boost, elevating it to an altitude of 250 miles. This altitude hoovers close to the station's highest elevation, according to Wikipedia, of 255 miles. Since this latest station re-boost was just the first of a series of planned re-boosts by the latest ATV, I was wondering if they were planning on using this ATV to take the station above 255 miles. If so, what is the ISS' highest planned altitude and when? What is the highest they can raise the station and still be accessible by Soyuz, HTV, ATV, Dragon, and Cygnus without sacrificing payload capacity?

I had to convert this one to miles.425 km = 264 milesThey're pushing it close! If Progress and Soyuz capsul are launched on a Soyuz 2 rocket, does the range and capacity go up?
Some ISS power/solar array questions!•Do the U.S. segment arrays now provide all the power, or are the Russian module ones still used?•How much power in watts does each U.S. and Russian solar array/wing generate?

SM array power output is unknown to me.
The RWS has components which are either external or internal to the rack. The external components, illustrated in Figure 8-6, are portable and include three video monitors, a Translational Hand Controller (THC) and a Rotational Hand Controller (RHC), a Display and Control (D&C) panel, a Portable Computer System (PCS), and an Artificial Vision Unit Cursor Control Device (AVU CCD). Unlike the external components, which are moved between the Lab and the Cupola, the internal components are fixed into the Lab racks. The internal components include an AVU and a Control Electronics Unit (CEU) which houses the RWS software.
I would like to clarify the capabilities of the different grapple fixtures used on USOS...I don't understand what is an EFGF.Also, I don't understand the usefulness of transmitting a video signal between SSRMS and its payload...
