Once the tents are pitched we put on a star party with assistance from the National Preserve staff, leaders of the [...]

A visit to the Lunar Sample Laboratory Facility

My favorite sign at JPL is this Rover Xing sign.

It is not unusual to see [...]

Clarissa's catblog

Meow! I am Jane and Mojo’s cat, Clarissa. I’m a gorgeous (if I do say so myself) eight year-old Tortoiseshell Tabby cat. I asked Jane to take some pictures and video of me to share with all you cat lovers. I hope you like them!

I love my Science Diet Savory Chicken cat food
