SUMMARY

The Gravity Probe launch, a significant experiment for testing General Relativity (GR), is set to occur after nearly 40 years of preparation. The satellite is designed to observe effects predicted by GR that have never been documented before, potentially validating GR against alternative theories. The discussion highlights the precision required for the launch window, which is as narrow as one second, raising questions about the control systems in place to manage unforeseen atmospheric anomalies during the launch process.

PREREQUISITES
  • Understanding of General Relativity (GR)
  • Familiarity with satellite launch procedures
  • Knowledge of atmospheric science and its impact on aerospace operations
  • Experience with precision timing in engineering applications
NEXT STEPS
  • Research the technical specifications of the Gravity Probe satellite
  • Explore the control systems used in rocket launches
  • Study atmospheric anomalies and their effects on aerospace engineering
  • Investigate previous experiments testing General Relativity
USEFUL FOR

Aerospace engineers, physicists, and anyone interested in the practical applications of General Relativity and satellite technology will benefit from this discussion.

Gravity probe launching countdown :
For those who haven't heard yet...After almost 40 years ,one of the neatest experiments for testing GR will be finally conducted :
http://einstein.stanford.edu/
 
Physics news on Phys.org
Predictions from GR have been made, and the expected effects are within the capabilities of the satellite ... these effects have not been observed before, so it will be yet another test of GR (and any remaining alternatives which can match the results of experiments and observations done to date, within the limits of observational error*).

*does anyone know of any?
 
Well, what a disapointment today. Hopefully tomorrow. The thing that most fascinates me is the narrowness of the launch window. It seems a bit extraordinary that the boosters can be so controlled during the procedure that we can use windows on the order of 1 sec. Furthermore, what about unforseen atmospheric anomolies? How can a window be specified so narrowly in light of the potential for a strong unforseen wind? Would such an occurrence devastate the launch attempt, or are there some elaborate control systems that accommodate for this?
