Join the military, the Air Force, specifically. to get in the satellite program or become a top Military Officer, CIA, FBI or even the President of the United States, with a "clearance" and a "need-to-know" and then and only then can you get "real time" or specific time satellite imagery.
While Google doesn't have its own satellite, and is instead provided imagery from other satellites, the imagery is usually 1-3 years old, according to google. So how old images are just depends on when google collects the images. But it is not possible to see images in real time using google earth.
One can view Earth from satellite images on Flash Earth, Symi Visitor, Google Earth, and Twisted Sifter. There is even an application called Satellite Live, which allows users to see real-time video of what is going on anytime, anywhere around Earth.
Absolutely not. Can you comprehend the phenomenal amount of money it would cost to have a satellite pointed at every sector of the globe, streaming data in real-time?
Satellite imaging. If you superimpose a satellite image of the Earth at a specific point with a satellite image of air pressure, and then expand those two images forward in time, you can get a decent estimate of what the whether is and is going to be at that point.
Maps may be drawn to scale or not to show more or less detail as needed. Satellite images on the other hand are actual photographs of what the ground and landscape are at a particular time. Both have many uses and tools like Google Maps allow you to switch from a map/street view to a satellite view with a click of the mouse.
If you mean get a "real time" satellite view similar to Google Earth, no. Try getting a job at a "spy" agency, although they still experience delays of minutes to hours in satellite images (as far as I know). On the other hand, there are many, many live Web Cams around the world with real time views of city streets and the like. See the link (one of many such Web Cam aggregators) for more.
Real time imaging refers to using a procedure which allows images to be captured in real time. In other words, like a movie as opposed to a still photograph.
Light microscope
Go the the link below, which is the NASA site for the "J-Track" real-time satellite animation. It will show the up-to-the-minute positions of hundreds of satellites, including the Lacrosse satellite.
