__3 things I've learned:__ - The first completely successful mission of a spy satellite came on Aug. 18, 1960, when an American CORONA reached orbit. - The best time is the first hour or two after sunset to site a satellite on a clear night. - Yuri Gagarin of the Soviet Union was the first human to orbit the Earth, on April 12, 1961.

__2 things I've found interesting:__ - The worlds first weather satellite was the TIROS (Television Infrared Observation Satellite) on April 1, 1960. - On Aug. 18, 1960 the first spy satellite CORONA took pictures from space and shot the role of film which would parachute down to earth for the military to retrieve.

__1 question i still have:__ - is there an amount to the number of satellites that can orbit our planet

__3 things I've learned:__ - On May 9, Japan launched the world's first probe 'Muses-C which is designed to bring back samples from the surface of an asteroid in four years. During this period the spacecraft will cover nearly 600 million kilometers -The Beagle 2 is the newest mission to Mars. Built by Atrium for the United Kingdom, Beagle 2 will be the first lander since NASA's two Viking probes in the 1970s to look for indications of past or present life and water. The rovers "Spirit" and "Opportunity", will act as robot geologists for Mars. - NASA launched the science probe into what is called a 'trailing Earth orbit' which means SIRTF.

__2 things I found interesting:__ - The total number of space flights that happened in 2003 were 49 of which three were manned and the others unmanned - China became the third nation in the world to independently send probes into space.

__1 question i still have:__ - What was the most resent space mission launch to date

__3 things I've learned:__ - Siris and XM radio are the only two companies that provide satellite radio. - AM and FM radio transmit radio waves in a type of electromagnetic radiation. - In the 1960's deejays and entrepreneurs were tired of AM radio and switched to FM giving listeners more music and less chatter.

__2 things I've found interesting:__ - The new satellite radio plays one song after another without any commercials. - Satellite radio has 60 channels of music and 40 channels of news and talk shows

__1 question I still have:__ - When can this new technology "HSS" be exposed to the public.

__3 things I've learned__: - It is said that cave men probubly used stones and twigs to navigate during prehistoric ages. - GPS satellites takes 12 hours to orbit the earth to point things out. - During WWII both sides in battle used ground-based radio-navigation systems to find their enemy in ship and air fights.

__2 things I've found interesting:__ - Without GPS system the miltary would have a hard time protecting us and miltary depends on it. - GPS sytems are divided into 3 sections: Space segments, User segments, Control segments.

__1 question I still have:__ -can it work under water?
