Phoenix spacecraft humor

Now we know why the success rate of spacecraft to Mars has been so low.
According to the text associated with this image:

http://www.nasa.gov/mission_pages/ph..._full_001.html

the Phoenix has "octagonal solar panels" but in fact there appear to be
10 sides. Fortytwo possible explanations:

1) Mars is so far from Earth that space-time warping changes the way
edges are counted.

2) Eight in base eight is written 10, just as ten in base ten is written
as 10, so "octagonal" sometimes means "ten" such as during a full Phobos
moon.

8) The Martians are messing with our minds and attached two more panels
in the infamous 15-minute gap before they were deployed. Clever little
imps!
