First spacewalk wrapping up, WF/PC2 out, WFC3 in.
Command and Data Handling Unit swapped out.
WF/PC2 removed
Live updates on NASA twitter
WFC3 was installed successfully and signaled it was alive.
SIC&DH is installed.
John is putting on the external attachment for grapples to grab, in case NASA decides to robotically deorbit HST in the future.
Almost done. Gone put on rapid open kits for the HST access doors so future spacwalks can get on with things.
Remarkably successful so far.
When they were installingSIC&DH I heard on NASA TV "This is easier than in the tank."
Always a good sign!
If WF/PC2 is "whiff-pick-two", is WFC3 "we-f*ck-three"?
