2005 April To April 30
sol 449-455, May 6, 2005: Testing on Earth Before Moving on Mars
Opportunity is imaging the plains and performing atmospheric science observations while waiting for engineers on Earth to give it the go-ahead to move. The team is diligently working to determine why Opportunity dug itself into a small dune, the best way to exit the dune, and what added precautions to use during future driving.
Sol summary:
Sols 449 to 455 (April 29 to May 5, 2005):
In JPL's In-situ Instrument Laboratory sandbox, engineers, scientists and even the project manager have been mixing sandy and powdery materials, digging holes and building dunes. A mixture was concocted to simulate properties of the soil underneath Opportunity, using sand, clay and diatomaceous earth (silica-rich powder composed mainly of microscopic plant shells, used in these tests for its texture, not its fossil origin). The team wants to have a full understanding of how Opportunity will respond before commanding it to back out of its current position.

Famous quotes containing the word april:
“In April 1917 the illusion of isolation was destroyed, America came to the end of innocence, and of the exuberant freedom of bachelor independence. That the responsibilities of world power have not made us happier is no surprise. To help ourselves manage them, we have replaced the illusion of isolation with a new illusion of omnipotence.”
—Barbara Tuchman (1912–1989)
