[Graham E. Lau]

Definitely is. Gary Trubl would be a good person to reach out to if you want to see if anything has come from the workshop since.

Hii, 

Is speed of Light direction ? I mean we have measured the speed of light in lap but can we measure in one way ??

[Graham E. Lau]

I'm not entirely sure what you mean, Amaan. The speed of light has dimensions of distance per unit of time and tells us about how fast light travels through space in a vacuum.

In the event that active life or fossil evidence is found on Mars it is likely to fall into one of three categories; Panspermia, new genesis, or back contamination from Earth. Do we have contingencies for each of these categories or identification protocols?
