What are facts about the hubble telescope?

Answer 1

Hubble Space Telescope's Name:
NASA named the world's first space-based optical telescope after American astronomer Edwin P. Hubble (1889-1953). Dr. Hubble confirmed an "expanding" universe, which provided the foundation for the Big Bang theory.
Cool Fact:
Scientists believe our universe began with a "big bang" some 13.7 billion years ago. If all the events in the history of the universe until now were squeezed into 24 hours, Earth wouldn't form until late afternoon and humans would have existed for only 2 seconds.

Hubble Space Telescope's Mission:

• Launch: April 24, 1990 from space shuttle Discovery (STS-31)
• Deployment: April 25, 1990
• Mission Duration: Up to 20 years
• Servicing Mission 1: December 1993
• Servicing Mission 2: February 1997
• Servicing Mission 3A: December 1999
• Servicing Mission 3B: February 2002

Hubble Space Telescope's Size:

• Length: 43.5 ft (13.2 m)
• Weight: 24,500 lb (11,110 kg)
• Maximum Diameter: 14 ft (4.2 m)

Hubble is nearly the size of a large school bus-but it can fit inside a space shuttle cargo bay.

Cost at Launch:
$1.5 billion
Spaceflight Statistics:
The Hubble Space Telescope whirls around Earth at a speed of 5 miles per second. If cars moved that fast, a coast-to-coast trip across the continental United States would take only 10 minutes. Orbit: At an altitude of 307 nautical miles (569 km, or 353 miles), inclined 28.5 degrees to the equator (low-Earth orbit)
Who built the Hubble?
Lyman Spitzer Jr. was the one who came up with the idea of "a space telescope". NASA liked the idea and soon funding was coming in from the government and universities. In 1990 the Hubble was completed and launched into orbit.
