Hubble's orbit above the Earth's distorting atmosphere allows astronomers to make the very high resolution observations that are essential to open new windows onto planets , stars and galaxies. Hubble was designed as a high standard flagship mission and has paved the way for other space-based observatories. Notably it can access the otherwise invisible ultraviolet part of the spectrum, and also has access to areas of the infrared not visible from the ground. The Hubble Space Telescope is named after Edwin Powell Hubble who was one of the great pioneers of modern astronomy.
Design: At the heart of Hubble are a 2. Hubble is equipped with cameras, spectrographs and fine guidance sensors.
The observatory was designed to be serviced in space, allowing outdated instruments to be replaced. The telescope was placed into a low-Earth orbit by the Space Shuttle and uses modular components so that it can be recovered on subsequent Shuttle Servicing missions and faulty or outdated parts more easily replaced before being re-released into orbit.
Power: Power for the computers and scientific instruments onboard is provided by two 2. Solar panels are those devices which are used to absorb the sun's rays and convert them into electricity or heat. Description: A solar panel is actually a collection of solar or photovoltaic cells, which can be used to generate electricity through photovoltaic effect. These cells are arranged in a grid-like pattern on the surface of solar panels. Thus, it may also be described as a set of. An aurora is a natural phenomenon which is characterised by a display of a natural-coloured green, red, yellow or white light in the sky.
It is predomi. ISRO was formed in with a vision to develop and harness space technology in national development, while pursuing planetary exploration and space science research. A Lagrangian point is a position or location in space where the combined gravitational forces of two large bodies is equal to the centrifugal force that is felt by a third body which is relatively smaller.
The two large bodies here may be the Earth and Sun or the Earth and Moon. Description: A lagrangian point is also known as a Lagrange point, Liberation point, or L-point. These points are loc.

The homosphere is the lower segment of the two-part division of atmosphere and further consists of three regions namely troposphere, stratosphere and mesosphere.
Strangely, soon after its launch, Hubble was not sending back to Earth the types of images that should have come from such a powerful telescope. The mirrors on Hubble, 2. Scientists discovered, however, that one of the mirrors known as the primary mirror had been ground too flat on one edge.
Scientists had to fix this problem somehow, so they decided to fit Hubble with a corrective lens, kind of like a pair of glasses. So, during a special shuttle mission, the astronauts took the corrective lens up to space with them, and they fitted it on Hubble. Currently, Hubble is sending spectactular images of distant galaxies and stellar phenomena that have never been seen before.
To make it able to do this, Hubble has many more instruments aboard than just its mirrors.
