Telescope to be launched on giant stadium-sized balloon - Daily Mail

A telescope will be launched into the upper atmosphere strapped to a balloon the size of a stadium next year, and it will be able to take images that rival Hubble, scientists behind the project claim.

The telescope has a 0.5 metre diameter mirror and will be able to remain in the air for months at a time thanks to a new NASA superpressure balloon design.

Unlike the James Webb telescope, launching in November and working in infrared, SuperBIT will operate in similar frequencies of light to Hubble, leaving the scientists behind the project to tout it as a natural successor to the ageing observatory. .

The NASA Super Pressure Balloon is a sealed structure that is filled with a measured and specific amount of Helium lifting gas. .

The balloon rises after launch, and the Helium expands as the ambient atmospheric pressure goes down. .

The Super Pressure Balloon is designed to fly with a positive internal pressure at all times. .

The Superpressure Balloon-borne Imaging Telescope (or SuperBIT) has a 0.5 metre diameter mirror and is carried to 40km altitude by a helium balloon with a volume of 532,000 cubic metres, about the size of a football stadium.

This should enable a telescope to obtain images as sharp as those from the Hubble Space Telescope, explained the team.

'Apart perhaps from Galileo’s first use of a telescope for astronomy in 1609, Hubble has been the most important telescope in the history of astronomy

'The Hubble Space Telescope is definitely one of the most successful space missions ever. 

'Without the Hubble Space Telescope, it would be much more difficult for me to do my work in studying Jupiter’s northern and southern lights. 

Something only possible with Hubble every few years during the Space Shuttle era

In the longer term, the Hubble Space Telescope will not be repaired again when it inevitably fails - it was originally expected to last for a decade but thanks to extensive repairs and upgrades, it has been going 30 years

The Hubble telescope was launched on April 24, 1990, via the space shuttle Discovery from Kennedy Space Centre in Florida

The Hubble telescope is named after famed astronomer Edwin Hubble who was born in Missouri in 1889 (pictured)

The Hubble telescope is named after Edwin Hubble who was responsible for coming up with the Hubble constant and is one of the greatest astronomers of all-time
