Canada to launch satellites to reduce the risk of collisions in Earth's orbit

Scientists estimate that there are more than 20,000 satellites and debris in Earth's orbit. Some of these satellites

no longer work, and some debris is difficultto identify - these are thousands of spent rocket stages, which over time broke off and became smaller pieces. Collisions with them can lead to disastrous consequences.

Therefore, NorthStar Earth & Space fromMontreal said it will launch the first commercial satellite network in 2022 to reduce the threat of collisions between objects in space. Thales Alenia Space will build the first three satellites.

“People tend to forget that today wereally addicted to space travel. When you look at your smartphone, 40% of the applications that we have rely on data from space - this is the weather forecast, navigation, and sometimes the telephone itself. "

press release NorthStar Earth & Space

According to the European Space Agency(ESA), over the past 20 years, about 12 accidents due to space debris have occurred annually in low-earth orbit. While modern technology relies on ground-based telescopes to track potentially hazardous space debris and satellites, NorthStar will have satellites equipped with telescopes in orbit around the Earth, resulting in vastly improved accuracy.

Scientists added that ground-based telescopes are wrongare accurate and may not work due to adverse weather conditions. The NorthStar satellites are a good step towards getting more accurate information on how close satellites and space debris are to each other.

Formerly the International Space Station (ISS)dodged a collision with unknown space debris. Shortly before this, a source at the Mission Control Center in Moscow said that a dangerous approach of the ISS with an unrecognized space object was predicted, in connection with which a station evasion maneuver was planned.
