How LEO satellite technology can connect the unconnected
2022年2月18日 · Low-earth orbit (LEO) satellites can help connect the unconnected and bridge the digital divide. The race to deploy LEO satellite constellations is increasingly competitive and will require multi-stakeholder cooperation to deliver inclusive connectivity. The World Economic Forum’s EDISON Alliance is mobilizing a global movement of leaders ...
Where does space junk come from – and how do we clean it up?
2021年5月5日 · Some debris is created naturally from the impacts of micrometeoroids – dust-sized fragments of asteroids and comets. With limited lifetimes, operational satellites can become space debris. Satellites run out of maneuvering fuel, batteries wear out, solar panels degrade – causing an orbital debris feedback loop, in which the problem is ...
UN calls for space regulation as Earth's orbit gets more crowded ...
2023年9月4日 · The UN report notes that “the number of satellites launched into outer space has increased at an exponential rate from 210 in 2013 to 600 in 2019, to 1,200 in 2020, and to 2,470 in 2022.”. These recent launches are adding to the congestion in low-Earth orbit. The Union of Concerned Scientists (UCS) keeps a database of all satellites deployed.
Space junk: what it is and why cleaning it up matters
2021年5月20日 · Space junk can travel at 40,000km an hour and can destroy satellite communications. A new space mission is aiming to capture and remove space debris from orbit. In November 2021, the crew of the International Space Station were forced to take shelter onboard to avoid being struck by pieces of a broken satellite orbiting Earth. Just eight months ...
Why space debris is a growing problem | World Economic Forum
2023年6月13日 · Share: Space-related technologies have allowed people in remote areas to access the internet, and have powered numerous innovations. This and future progress is under threat because of orbital debris, human-made objects in orbit that no longer serve a useful function. These pieces of debris travel several times faster than a bullet; a collision ...
Global Risks Report 2022 - The World Economic Forum
2022年1月11日 · Once in orbit, and unless actively decommissioned, many of these satellites could remain in space for hundreds of years. 14 Smaller, low-cost satellites are also proliferating because of lower costs and fewer barriers to entry. 15 While the risk is still relatively low, an increase in the number of satellites also increases the opportunity for collisions, or, at the …
Environmental impact of space debris and how to solve it | World ...
2022年7月13日 · Over the past six decades, about 11,000 satellites have been launched, of which 7,000 remain in space. But that number could swell to the hundreds of thousands by the end of this decade as private companies like Elon Musk’s Starlink and Amazon join China and other nation states in building mega-constellations in Low Earth Orbit (LEO).
These are the top 10 emerging technologies of 2021
2021年11月16日 · With the recent advent of countless low-cost microsatellites in low earth orbit able to capture such data globally and download it to central facilities for processing, the IoT will enable unprecedented levels of global understanding—encompassing previously inaccessible developing regions devoid of traditional Internet infrastructure.
How Earth observation satellites aid climate change research
2024年5月16日 · By 2030, the Earth observation field is expected to contribute over $700 billion to the global economy and reduce annual greenhouse gases by 2Gt, according to a new World Economic Forum report. When ERS-2 came spiralling down to Earth in March, it wasn’t just another satellite burning up in the atmosphere.
