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:
“Postmodernism is, almost by definition, a transitional cusp of social, cultural, economic and ideological history when modernism’s high-minded principles and preoccupations have ceased to function, but before they have been replaced with a totally new system of values. It represents a moment of suspension before the batteries are recharged for the new millennium, an acknowledgment that preceding the future is a strange and hybrid interregnum that might be called the last gasp of the past.”
—Gilbert Adair, British author, critic. Sunday Times: Books (London, April 21, 1991)
