SUMMARY

A satellite designed to test Albert Einstein's predictions regarding the universe is set for launch, 45 years after its initial proposal. The satellite aims to measure two specific general relativity effects on gyroscopes: the geodetic effect, which results in an anomalous precession of approximately 6.6 arcseconds per year, and the Lense-Thirring effect, which predicts a precession of 0.042 arcseconds per year. This mission represents a significant advancement in experimental physics and our understanding of gravitational effects in space.

PREREQUISITES
  • Understanding of general relativity principles
  • Familiarity with gyroscopic motion and precession
  • Knowledge of satellite technology and space missions
  • Basic grasp of astronomical measurements and units
NEXT STEPS
  • Research the geodetic effect in general relativity
  • Explore the Lense-Thirring effect and its implications
  • Study the design and objectives of NASA's satellite missions
  • Investigate the historical context of Einstein's predictions
USEFUL FOR

Astronomers, physicists, aerospace engineers, and anyone interested in the experimental validation of general relativity and satellite technology.

A satellite designed to test two fundamental predictions made by Albert Einstein about the universe is ready for launch, 45 years after it was first proposed, NASA and Stanford University officials said Friday.

I was just about the post the same :)
So how large would they predict the deviation to be after two years?

Monique; there are two GR effects predicted upon the gyroscopes.
One is a geodetic effect (due to the 'curvature' of space-time) which amounts to an anomalous precession of about 6.6arcseconds per year.

The other is the Lense-Thirring (frame dragging) precessional prediction which comes to only 0.042 arcseconds/yr. :biggrin:
