Gigantic helium balloon to launch space telescope

to read

It weighs as much as a car, and will be launched to the edge of space by a helium balloon the size of a football stadium. Professor Richard Massey from our Centre for Advanced Instrumentation collaborated with NASA, the Canadian Space Agency and Toronto and Princeton universities.


The science goal for SuperBIT’s 2022 flight is to obtain high-resolution images to measure the properties of dark matter. Although dark matter is invisible, astronomers map it by the way it bends rays of light, a technique known as gravitational lensing.

Space telescope

SuperBIT will take image of the sky at night, then use solar panels to recharge its batteries during the day.

A test flight of the telescope in 2019 demonstrated extraordinary pointing stability, sufficient to thread a needle 1km away. This stability is needed to take images as sharp as those from Hubble Space Telescope.


Balloons, not rockets?

SuperBIT will be carried by an experimental balloon from NASA, which can retain helium for months, and circumnavigate the Earth.

Compared to rockets, balloons are a cheap and environmentally friendly way to reach space. They also make it possible to develop the telescope technology over several test flights.

Measuring dark matter

The science goal for SuperBIT’s 2022 flight is to obtain high-resolution images to measure the properties of dark matter. Although dark matter is invisible, astronomers map it by the way it bends rays of light, a technique known as gravitational lensing.

SuperBIT will test whether dark matter slows down during collisions. The collisions are the occasional, natural mergers between galaxies - all of which are surrounded by vast clouds of dark matter.
