Availability of Earth Materials. Current Administrator Michael Griffin revisited the Hubble servicing mission decision and rejected the robotic servicing mission option, calling the $1 billion plan too costly. It points to the potential of the space program Although the Hubble Space Telescope is not without its disadvantages, the fact of the matter is that it has been more successful than not. So far, astronomers have been able to correct Hubble images by layering multiple exposures. Space-based telescopes like Hubble get a much clearer view of the universe than most of their ground-based counterparts.

It points to the potential of the space program. Hubble has advantages over most telescopes when it comes to making detailed images of celestial objects like the Eagle Nebula. He has also revisited the idea of a Shuttle repair flight, and pending successful Shuttle operations in the near future, NASA is preparing to send a mission to Hubble before the Space Shuttle is retired by the end of the decade. Earths atmosphere changes and blocks some of the light that comes from space. This is not because such telescopes are materially closer to their objects of inquiry, but rather because the Earth's atmosphere can distort images so badly. The most recent servicing mission to the spacecraft, servicing mission 3B, came aboard STS-109 in March, 2002. OneWeb has more than 500 satellites in its own broadband constellation. Other NASA studies had also originally called for space telescopes, albeit using smaller mirrors that the 120-inch size proposed by the National Academy of Sciences. As it continued to return groundbreaking photos of the universe and help astronomers do valuable research, the Hubble Space Telescope's future would once again be thrown into uncertainty by a Space Shuttle tragedy. Wider wavelengths of the electromagnetic spectrum can be observed such as infrared, ultraviolet, x-rays and gamma rays.

What are the advantages and disadvantages of using a Space Telescope? There are many different types of space telescopes. Hubble orbits the Earth at a cruising speed of 17,000 miles per hour, and takes 15 minutes to rotate 90 degrees. Born in 1889, Hubble discovered that many objects previously thought to be clouds of dust and gas and classified as nebulae were actually galaxies beyond the Milky Way. It's much more efficient to build a bigger telescope on Earth for fewer dollars. It's in space!
