How tall is the Hubble Space Telescope?
Launched from space shuttle Discovery on April 24, 1990, the Hubble Space Telescope orbits at an altitude of about 350 miles (560 kilometers). The telescope is 43.5 feet (13.2 meters) long, weighs 24,500 pounds (11,110 kilograms) and cost $2.5 billion.
Is the Hubble telescope the largest telescope?
Edwin Hubble, for whom the Hubble Telescope is named, used the largest telescope of his day in the 1920s at the Mt. Wilson Observatory near Pasadena, Calif., to discover galaxies beyond our own. Hubble, the observatory, is the first major optical telescope to be placed in space, the ultimate mountaintop.
What are the dimensions of Hubble?
Hubble is 43.5 feet long (13.2 m) and 14 feet wide (4.2 m) at the back, where the scientific instruments are housed. Weighing about 27,000 pounds (12,246 kg), the telescope is approximately the same size and weight as a school bus.
What is the Hubble Space Telescope made out of?
Instead of a solid core, Hubble’s primary mirror has a honeycomb core, reducing its weight from 8,000 pounds (3,636 kg) to 1,800 pounds (818 kg). Both mirrors are coated with thin layers of aluminum and magnesium fluoride.
Where is Voyager now?
Voyager 2 has been traveling through space since its launch in 1977, and is now more than 11.6 billion miles ( 18.8 billion km) from Earth.
How far away is Voyager 1 2020?
22.3 billion kilometers
Is NASA still in contact with Voyager 1?
Even though Voyager 1 and 2 are now 43 years old and farther from Earth than any other operating spacecraft in history, however, they’re not lost to us yet. The key is through NASA’s Deep Space Network: a collection of radio antennae designed to communicate with humanity’s most distant spacecraft.
How far away is Voyager now?
14 billion miles
Where is the farthest satellite in space?
At present the farthest space probe mankind has constructed and launched from Earth is Voyager 1, which was announced on December 5, 2011, to have reached the outer edge of the Solar system, and entered interstellar space on August 25, 2012.
What is the farthest man has traveled into space?
The record for the farthest distance that humans have traveled goes to the all-American crew of famous Apollo 13 who were 400,171 kilometers (248,655 miles) away from Earth on April 14, 1970. This record has stood untouched for over 50 years!
