Other Drag-Free Missions

The Websites Linked On This Page Seem to Be Either In an Early Planning Stage Or Are Competing With Other Mission Proposals

  1. The GOCE Mission

  2. MICROSCOPE (Equivalence Principle Test)

  3. The "Galileo Galilei" (GG) Mission to Test the Equivalence Principle Also see the Phase A Study: Chapter 2

  4. The ONERA MICROSCOPE Mission (See also MICROSCOPE Performance Summary)

  5. The SMEX Phase A Study (This is the latest version of STEP)

  6. SEE Project for Testing Gravity in Space: Current Status and New Estimates (Measure: G to 10^-7, Equivalence Principle, and Inverse Square Law)

  7. GPS Precision Enhancement Using Drag-Free Technology

  8. GRACE: Gravity Recovery and Climate Experiment. GRACE is not a Drag-Free mission per se, but it is included here because it works on similar principles and because it's purpose is to study the earth's gravity field. Furthermore, it has been successfully launched is presently taking data.
