-- Test of General Relativity ?! --

"Scientists sent radio signals to the lander on Mars, and instructed the lander to send back signals. Scientists then found that the time signals needed to make a round trip match the prediction of Gravitational Time Dilation."

Well, time dilation due to (rather feeble) gravity field of Mars will be many orders of magnitude smaller than delay due to uncertainty of Earth-Mars distance, delays in electronics which processes received signal and sends echo back, and even slight variations of signal propagation thru the solar wind.

If I am wrong, I would like to read about this experiment. Any URLs?

--168.169.63.253 13:30, 26 May 2006 (UTC)do you know anything about vikings? I am doing a project for social studies.

Did the Viking use a digital camera? Sorry if this sounds like an obvious question but it just occured to me that the photos would have to have been transmitted electronically, meaning the photos could never have been film, right? The picture at the top of the article (with the rock left of centre) is of amazing quality for a digital camera of 1975. I never even knew they had them back then! --Matt0401 11:49, 27 September 2006 (UTC)

• The Viking cameras were digital, yes, and worked kind of like a scanner, so that the image was created by sweeping a vertical line of sensors from left to right to create a panorama. This put very simple, of course. The original data is of very high quality. Ricnun 22:16, 27 September 2006 (UTC)
