Global Positioning System (GPS)?
I used to have Global Positioning System (GPS) installed in my rental car from Hertz during US trips.
What is GPS?
The Global Positioning System (GPS) is currently the only fully functional Global Navigation Satellite System (GNSS). More than two dozen GPS satellites are in medium Earth orbit, transmitting signals allowing GPS receivers to determine the receiver’s location, speed and direction.
Since the first experimental satellite was launched in 1978, GPS has become an indispensable aid to navigation around the world, and an important tool for map-making and land surveying. GPS also provides a precise time reference used in many applications including scientific study of earthquakes, and synchronization of telecommunications networks.
Developed by the United States Department of Defense, it is officially named NAVSTAR GPS (NAVigation Satellite Timing And Ranging Global Positioning System). The satellite constellation is managed by the United States Air Force 50th Space Wing. The cost of maintaining the system is approximately US$750 million per year,[1] including the replacement of aging satellites, and research and development. Despite this fact, GPS is free for civilian use as a public good.

Homesickness
I was away for around 3 weeks, I’m homesickness now.
I missed my wife, my son, my family, my house, my bed, my car(right hand drive) Malaysia food, and many many….. I fell sad when I saw my colleague went back home last week during I sent them to airport. I don’t think I like the foods here, “fried”, “grilled”, “BBQ”, “burger”, “ham” almost the same everyday.

NASA’s Johnson Space Center – Houston
This is a late coming blog entry which I visited NASA Space Center – Houston last week. It took me total of 3 hours drive from Austin to NASA’s Johnson Space Center Houston and back with another 3 hour drive(tired).
The entry ticket cost us $18.95 + $5.00 astronaut audio tour + $5.00 car parking but I think this is fare enough. I’m highly recommend who would like to know more about space, astronaut, rocket must go. Check Space Center web site for more information.
