Space Probes and Satellites
Transcript of Space Probes and Satellites
What is a space probe?
A space probe is any
craft which is sent into space to do
. We will look at 3 basic types:
Sputnik 1 was the first probe to go into space.
It was launched on Oct. 4, 1957, by the former Soviet Union. It was about the size of a beach ball. It sent signals back to Earth for about
and orbited for
until it fell back to Earth and burned as it re-entered the atmpsphere.
Fortunately, space probes have really advanced over the years.
One of the most famous space probes is Voyager 1. It has traveled further in space than any human-made object. It launched into space in 1977. Voyager 1 flew past Jupiter and Saturn and then headed for the edge of our solar system. It has traveled over 11 billion miles. It will leave our solar system this year. (2016)
Curiosity (arrived August 2012, still active)
Opportunity (arrived January 2004, still active)
Spirit (arrived January 2004, last transmission March 2010)
Mars Pathfinder (arrived July 1997, last transmission Sept 1997)
Voyager 1 is a "flyby" space probe
The Magellan spacecraft was launched in early 1989 via the Space Shuttle Atlantis. It is an orbiter. In only four years, Magellan mapped 98% the surface of Venus. After many experiments and a lot of data collected, Magellan wasintentionally flown to its destruction in Venus's atmosphere in October 1994, all the while carrying out additional experiments. Magellan was a very successful orbiter.
Any craft that we launch into space that sends back information is a space probe. If it orbits a planet or moon it is also a satellite.
Some satellites are natural like our moon. It orbits Earth. This make the moon a satellite. However, it does not send us information.
All manmade satellites send information back to Earth. This makes them all space probes. Since they also orbit, they are space probes that are satellites.
If the manmade space probe doesn't orbit something then it is simply a space probe. It can either fly by planets, moons or other celestial bodies and take pictures or even land there.
