ISS Crew Completes EVA

NASA Space Station Status Report 28 March 2005

"The residents of the International Space Station ventured outside today for a 4-hour, 30-minute spacewalk to install communications equipment on the exterior of the Zvezda Service Module and deploy a small satellite experiment."

NASA Space Station On-Orbit Status 26 March 2005

"In a late change to their schedule, Sharipov and Chiao today replaced the #1 pump panel (4SPN1) of the Service Module (SM)'s internal cooling loop 2 (KOV-2). The panel failed early yesterday morning, causing a switchover to pump panel #2. Rather than isolating the failed pump, the entire 4SPN1 panel was replaced, to mitigate any contingencies from the thermal loop during EVA-13."

NASA Space Station Status Report 25 March 2005

"Early today, a thermal control loop panel in Zvezda that provides cooling to the Pirs airlock failed, and its backup system was activated to provide the necessary cooling. There are two circulating pumps associated with each panel. Both pump panels are needed to provide adequate backup capability for the spacewalk. The crew will troubleshoot the pump panel early Saturday, and replace one or both of the pumps in the degraded panel."

"Elektron is currently off. After it shut down again on Thursday evening (4:55pm EST), the crew attempted to restart it on Friday (3/18) without success."

New machines could turn homes into small factories, University of Bath

"A revolutionary machine which can make everything from a cup to a clarinet quickly and cheaply could be in all our homes in the next few years. Research by engineers at the University of Bath could transform the manufacture of almost all everyday household objects by allowing people to produce them in their own homes at the cost of a few pounds. The new system is based upon rapid prototype machines, which are now used to produce plastic components for industry such as vehicle parts."

Editor's note: Now if only you could get this thing to work in microgravity.

Editor's update: A NASA Watch reader informed me that NASA has indeed been looking at how to do this in space. Check out this In Situ Fabrication and Repair page at NASA MSFC. Another reader informed me that LaRC is also working on this technology (see this page) Indeed, they have a portable system that will be flying on a C-9 microgravity aircraft in August. Cool stuff.

ISS CMG2 is Offline

Editor's note: ISS CMG 2 (Control Moment Gyroscope), one of three aboard the ISS, is off-line because a RPCM (Remote Power Controller Module) opened, thus removing power to the CMG. This is the same RPCM that was installed last year during an EVA to replace another RPCM which had failed, also taking CMG 2 offline.

NASA Space Station On-Orbit Status 16 March 2005

"Early this morning, the external Remote Power Controller switch #17 (RPC-17) tripped open, shutting down CMG-2 (control moment gyroscope #2). Automatic software reconfigured the steering law for the two remaining gyros, CMG-3 & CMG-4. Assessment of the anomaly is underway. [After a similar "Failed Open" trip of RPC-17 on 4/21/2004, CMG-3 & CMG-4 performed nominally for two months, with the Russian ACS (attitude control system) thrusters ready to take over at any moment, until the power switch was replaced on 6/30/04 by Padalka and Fincke on EVA-9B.]"

Editor's note: Look closely at this image. In the right hand corner is a calendar (in Russian) which features a speed boat. Hmmm ... has the Texas Gulf coast lifestyle rubbed off on Salizhan - and the folks back home?

The Iran Nonproliferation Act and the International Space Station: Issues and Options, Congressional Research Service

"According to current plans, the National Aeronautics and Space Administration (NASA) will become dependent on Russia for certain ISS crew-related services beginning in April 2006 for which NASA must pay. Thus, the INA could significantly affect U.S. utilization of ISS. This report outlines the history of INA, its effect on Russian and Iranian proliferation, its impact on the ISS program, and options for resolving associated issues."

Editor's note: The following chart shows the updated ISS Flight Program Launch graphic.

This chart addresses the launches to the ISS during the next 20 months per CR 9183 (Reference Assembly Sequence) 10 March 2005 and the OZ Working Launch dates as of 3 March 2005).
