At last the probe is ready.
"NASA's Gravity Probe B spacecraft could begin testing Einstein's general theory of relativity as early as this week, according to mission
controllers at Stanford University.
The probe, said to be one of the most precise scientific instruments ever assembled, was initially scheduled to begin taking measurements within 45 to
60 days of its April 20 launch into Earth orbit. But mission controllers were forced to delay operations time and again after discovering minor
malfunctions in the spacecraft's microthrusters and observing unexpected behavior from its four gyroscopes."
More info about the probe can be found here: einstein.stanford.edu...
"To make measurements this small, Gravity Probe B engineers had to ensure that the spheres in each of the spacecraft's four gyroscopes would not
wobble enough to ruin the measurements. To do this, they designed and developed some of the most perfect spheres ever created by humans. Composed of
fused quartz, the objects the size of a Ping-Pong ball have no imperfections greater than 40 atomic layers in height. In other words, if the spheres
were the size of the Earth, there would be no hills or valleys taller or deeper than 12 feet."
I find this pretty interesting and am looking forward to seeing the results.
What do people here think? Is this experiment really enough to measure and/or prove Einstiens theory? Can we consider the results as hard fact or do
you think outside influences in space will effect the measurements?
