UVic's minisatellite is due to launch in 2020 and investigate dark energy



Using a laser pen and a baseball-sized model ball, Bryce Edwards demonstrated how the 10-cm-wide minisatellite will diffuse the light and give astronomers a chance to better understand the origins and future of the universe. 19659002] This small satellite, called the CubeSat, can help astronomers explore the origins of the universe, according to Edwards.

Although so small, the CubeSat could minimize the problem of dark energy and uncertainties in astronomical measurements by a factor of up to 10. In orbit, a laser light emitted by the satellite will act as a sort of artificial star to better serve ground-based optical telescopes calibrate.

"We still do not know much about dark energy and that can help us measure that," said UVic astronomy student Ruth Digby, who explained the benefits of CubeSat on Friday.

It measures 1

0 cm x 10 cm x 10 cm and packs a lot of technology in a small space. The student project was conducted on Friday with the UVic Satellite Design Team, which presented the project at the UVic observatory in the Bob Wright Center.

The main function of the CubeSat is the light measurement. It will be launched by the International Space Station in 2020 and will have many implications for astronomy and can be used by observatories around the world.

"If you take a picture of a satellite from the ground, and one from the sky, then we can compare it and see how much light we get," Edwards said.

The CubeSate will orbit the world in about 90 minutes at about seven kilometers per second, for about two years. At that time, the small amount of atmosphere at the outer borders of the Earth will have generated enough friction to pull the small satellite back into the atmosphere where it will burn again on reentry.

CubeSat has been renamed by the new National Post-Secondary Student Space Initiative today called the Canadian CubeSat Project.

The team consists of more than 20 UVic engineering students working with UBC and SFU, such as the ORCAASat team (optical and radio calibration for atmospheric attenuation satellites). a total of about 50 people from different disciplines.
