Go for GOCE

The ESA’s gravity spacecraft couldn’t get off the ground yesterday, but it’s a "go" for today:

Attempt One Issue:

“The doors on the launch service tower did not open,” noted ESA. ”Due to this anomaly, the tower was held in position and did not move back as required for a launch.”

I suspect some people around the St. Patrick’s Day parade in New York will be dealing with gravity issues today. More about GOCE:

Clarified by Isaac Newton in the 17th century, gravity is a fundamental force of nature. Everything that has mass is pulled by gravity. As Earth is not a perfect sphere and its interior has layers and zones of different density, gravity varies around the globe.
Gravity and its variation in space are fundamental for every dynamic process on Earth’s surface and in its interior. Improving our knowledge of how gravity affects the interaction between these processes has practical benefits in today’s changing world.

An accurate gravity map – the geoid – is also crucial for geodesy applications and for defining a sea surface height reference model with which to accurately survey ocean circulation patterns and sea-level changes.
