So, the GFR Part II tasks are as follows:

1) SPDM OTCM picks up MFT (Multi Function Tool) from RRM
2) MFT picks up TVA (T-Valve Adapter) from RRM
3) TVA is used to remove and stow a T-valve on RRM
4) MFT places TVA back on RRM and picks up ACA (Ambient Cap Adapter)
5) ACA is used to remove and stow an ambient cap on RRM
6) MFT places ACA back on RRM and picks up PMA (Plug Manipulator Adapter)
7) PMA is used to manipulate plug beneath ambient cap
8 ) MFT places PMA back on RRM and picks up TCA (Tertiary Cap Adapter)
9) MFT (with TCA attached) is placed back into RRM by SPDM OTCM

GFR Part II complete. Next task: Refueling demo, scheduled for this summer.

Status Update

June 20, 2012
— By the end of their first day back on the job, RRM and Dextre had successfully used the Multifunction Tool to remove and stow a T-valve, the first of four main tasks on the docket for Part II of the Gas Fittings Removal Task. The Ambient Cap Adapter is now in place at the end of the Multifunction Tool, ready to complete the next round of operations on the International Space Station.

The RRM and Dextre duo made history in March when Dextre severed two extremely thin wires (the thickness of four sheets of paper) with only a few millimeters of clearance on the ambient cap — the most precise task performed by a robot in space to date. During the second day of RRM operations, Dextre will use the RRM Multifunction Tool with its corresponding Ambient Cap Adapter to remove and stow an ambient cap — a piece of hardware that would cover important fluid and gas lines on a real satellite. Mission operators will also use the Multifunction Tool to remove and manipulate a plug (located under the ambient cap) on the RRM module. Stay tuned for the next update!

Awesomeness. And you know the T-Valve was loose because the valve's top started to wobble, and then when the tool stopped rotating, the valve kept spinning.  :)

The only issue was that Dextre and the RRM weren't perfectly aligned, as you could see the camera on Dextre shift slightly (the view of the RRM translated at one position of the rotation task, and then back again).

Other than that, sweet!

Status Update

June 21, 2012
— At the end of this second day of operations, Dextre has shown the RRM Multifunction Tool's versatility in completing satellite-servicing tasks. During the last few hours, Dextre used the Multifunction Tool and the Ambient Cap Adapter to remove and stow an ambient cap — a piece of hardware that would cover important fluid and gas lines on a real satellite. The Multifunction Tool also picked up the Plug Manipulation Adapter, which it will use to remove and manipulate a plug located under the ambient cap on the RRM module.

The Multifunction Tool, or "MFT," was designed to be compact and multipurpose so that it can deliver smart and cost-effective servicing options in space. To date, Dextre and MFT have picked up three different adapters to remove and manipulate representative satellite hardware on the RRM module. Now that these activities have been successfully completed, the RRM team will use the last day of operations to manipulate a plug and prepare for the namesake Refueling task. Stay tuned for the next update!

From ISS On-Orbit Status Report for 21/06/12

RRM Update:
The first of three days of RRM (Robotic Refueling Mission) operations came to a successful conclusion last night with NASA & CSA (Canadian Space Agency) ground teams completing all scheduled satellite-servicing tasks using the NASA RRM module and the Canadian SPDM (Special Purpose Dexterous Manipulator) robot. Remotely controlled from the ground by mission operators at NASA JSC, SPDM “Dextre” used the RRM MFT (Multifunction Tool) to remove and stow a T-valve on the RRM module, the first of four main tasks scheduled for this set of operations.  The MFT, developed at NASA’s Goddard Space Flight Center (GSFC), is in position to demonstrate the next two satellite-servicing tasks on the RRM module: removing and stowing an ambient cap, and manipulating a plug located under the ambient cap. Today, NASA & CSA teams also successfully completed all scheduled satellite-servicing tasks, with SPDM using the RRM MFT and its connected ACA (Ambient Cap Adapter) to remove and stow an ambient cap on the RRM module. The module and Dextre are in position for their last current tasks, to manipulate a plug located under the ambient cap and begin preparations for the refueling demonstration in late summer 2012. RRM operations demonstrate the tools, technologies, and techniques needed to robotically repair and refuel satellites on orbit, especially those not designed to be serviced.

Status Update

June 22, 2012 — June RRM operations have successfully concluded, thanks to the excellent work of the teams at NASA's Goddard Space Flight Center, the Canadian Space Agency, and NASA's Johnson Space Center. RRM is now ready to practice and test the task of on-orbit refueling — a capability that would keep on-orbit satellites operating longer and more cost-efficiently in space.

During the last day of operations, Dextre and the Multifunction Tool used the Plug Manipulation Adapter to — you guess it — manipulate a plug that was located under the ambient cap on the RRM module. Next, Dextre and the Multifunction Tool picked up the Tertiary Cap Adapter, the last task assigned to the Multifunction Tool for this set of operations. Dextre safely stowed the Tool and the connected adapter so that when RRM operations begin again, the pair can remove a tertiary cap — an early step to demonstrating fluid transfer on the RRM module. Dextre also checked out the lights on the RRM Nozzle tools in preparation for the upcoming Refueling task. Prepared to make robotic history yet again, RRM and Dextre are tentatively scheduled to begin the highly anticipated Refueling demonstration later this summer. Until then, continue to check the SSCO website, Facebook and Twitter for more updates on the Robotic Refueling Mission and NASA's satellite servicing activities. Thanks for visiting!
