Does someone have images of the transport car on ISS?

[willpittenger]

ISS's transport car broke a cable somehow. How did it happen? How will we prevent it from happening again? I think drawings would be easier to understand. <div class="Discussion_UserSignature"> <hr style="margin-top:0.5em;margin-bottom:0.5em" />Will Pittenger<hr style="margin-top:0.5em;margin-bottom:0.5em" />Add this user box to your Wikipedia User Page to show your support for the SDC forums: <div style="margin-left:1em">{{User:Will Pittenger/User Boxes/Space.com Account}}</div> </div>

The transport car is the Mobile Transporter (MT). There are two cables that go to it carrying power and data. The two cables provide redundancy. However, they only provide power/data to the MT itself and not the arm or payloads when fixed on the MT. Therefore, to provide power to that, the MT has to be at a worksite where it can lock down and connect with the power/data fixtures. Now, if you had the arm/payload on the MT and where translating between worksites, you would not want the cables to get caught on anything or unable to reel out/in because then your arm/payload would not have power. In a short order of time, it would freeze. So to prevent the MT from getting to a worksite in this case, cable cutters were installed on each one with a pyro cutting edge. If needed, you could cut the cable and get to the worksite. Unfortuantely, early this year one of the cutters, for reasons yet to be determined, cut the cable! Snick! At this point the cable cutters are deactivated and bypassed.

<b>Mission Highlights</b> <br /><br />The launch marked a milestone as Mission Specialist (MS) Jerry Ross became the first human to fly in space seven times, breaking his own and other astronauts' records of six space flights. His two spacewalks gave him a total of 58 hours and 18 minutes, surpassed only by Russian cosmonaut Anatoly Solovyev in human space flight history.<br /><br />Installation of the S0 truss was the primary objective and began with removal of the truss from Atlantis' payload bay. Mission Specialist Ellen Ochoa lifted it out with the station's robotic arm and maneuvered it onto a clamp at the top of the Destiny Lab. The truss contains navigational devices, computers, cooling and power systems needed to attach additional laboratories to the complex. Four spacewalks were required for the task. The truss will serve as a platform on which other trusses will be attached and additional solar arrays will be mounted to form a 356-foot-long space station.<br /><br />Between and during spacewalks, shuttle and ISS crew members transferred experiments and supplies between the shuttle and the station. They also transferred oxygen from the shuttle to one of four high-pressure gas tanks, used on the Quest Airlock to repressurize the module after spacewalks. Overall, 100 pounds of oxygen and 50 pounds of nitrogen were transferred.<br /><br />Initial tests of the movement of the Mobile Transporter were successful. ISS Flight Engineer Walz commanded the transporter, via a laptop computer, to move to a work site 17 feet down a rail spanning the 44-foot-length of the girder, then a second site and back to the first. Automatic latching did not occur due to minute lifting of the rail car but was accomplished by manual commands. Other transporter systems functioned perfectly.<br /><br />Tasks not accomplished on the mission were removal of the balky bolt from the backup cab

So where are the cables and cutters? <div class="Discussion_UserSignature"> <hr style="margin-top:0.5em;margin-bottom:0.5em" />Will Pittenger<hr style="margin-top:0.5em;margin-bottom:0.5em" />Add this user box to your Wikipedia User Page to show your support for the SDC forums: <div style="margin-left:1em">{{User:Will Pittenger/User Boxes/Space.com Account}}</div> </div>
