Does the Hubble Space Telescope have thrusters?
Hubble does not travel to stars, planets or galaxies. It takes pictures of them as it whirls around Earth at about 17,000 mph. Hubble has no thrusters. To change angles, it uses Newton’s third law by spinning its wheels in the opposite direction.
What is the magnification power of the Hubble telescope?
The Hubble’s mirror is 96 inches in diameter. At full magnification of 96X60 = 5,760 power the closest it could image Mars is at Mars closest opposition every 15 years at distance of 34,600,000 miles is the distance of Mars divided by Hubble maximum power equals seeing Mars as though it were 6,007 miles away.
Why does the Hubble Telescope have a blanket around it?
The blankets do this by reflecting the sun’s energy during the daylight portion of Hubble’s orbit around the Earth, retaining just enough heat to keep the components from getting too cold during its night-time orbit, and protecting the telescope from radiation and orbital debris.
Can we see Earth from space with Hubble telescope?
February 28, 2014 If the Hubble Space Telescope (HST) could observe Earth from its orbit 570 kilometers (350 miles) above Earth’s surface, it would in theory be able to see objects as small as 0.3 meters (30 centimeters). But it’s not possible to turn the telescope in an Earth-observing direction.
What happened to the Hubble Space Telescope on STS 103?
Servicing mission 3A in December, 1999 replaced all six of the telescope’s aging gyroscopes, which accurately point the telescope at its target. STS-103 astronauts also replaced one of the telescope’s three fine guidance sensors and installed a new computer, all in time to redeploy Hubble into orbit on Christmas Day.
What technology advances were used to build the Hubble Space Telescope?
Among the many technological advances used in the telescope’s construction was the computer-based laser grinding system used by Perkin-Elmer to craft the observatory’s primary mirror. NASA originally planned to launch in 1983, but the program experienced a considerable delay.
