Chances are small that space junk will destroy property or harm a person, and existing space law could deal with such an event. But current law doesn’t address the bigger problem of space pollution.
China’s Long March 5B rocket, after a successful blast-off in April to deliver a space station module, is now on track to crash-land somewhere with a latitude between New York and New Zealand.
Earth orbit is filling up with satellites and space junk. Technological fixes can only go so far to deal with the problem.
Advanced techniques allowed our research team to build an open database of billions of individual trees and challenge some common perceptions about vegetation in arid and semi-arid zones.
Satellites impact our lives in many different ways, and some of these may surprise you.
Ten small satellites were launched from 11km above Earth’s surface.
The shift toward mega-constellations is a challenge for global space governance.
SpaceX’s satellites will populate the night sky, affecting how we observe the stars. And this is just the beginning of private satellite mega-constellations.
Radio telescopes are incredibly sensitive to phone network interference.
Satellite technology and machine learning are helping track down illegal and environmentally damaging ‘dark fleets’ of fishing boats.
By 2025 Elon Musk wants to launch 12,000 satellites and corner the global Internet market. What will be lost is earth-based astronomy, the idea that space belongs to us all and the beauty of a starry sky.
The COVID-19 pandemic hasn’t just disrupted our lives. It has also challenged the way we forecast the weather.
SpaceX and other companies are rushing to put thousands of small, inexpensive satellites in orbit, but pressure to keep costs low and a lack of regulation leave those satellites vulnerable to hackers.
Two defunct satellites passed within metres of one another, prompting renewed focus on the dangers of space debris. But with many satellites treated as military secrets, how do we track the hazards?
Free space optical communication will allow the same connectivity in space we already have on Earth. And this will provide benefits across a number of sectors.
India may soon follow in the footsteps of Asian space giants China and India, after the National Institute of Aeronautics and Space (LAPAN) announced a plan to build a spaceport in Papua.
Are India and China engaged in a new space race? India’s increasingly ambitious space ventures, including its Chandrayaan-2 lunar mission, are evidence of the country’s interest in space exploration.
We have developed an online tool to help authorities identify which areas they should focus on for reducing forest fires and haze in order to maximize overall health benefits.
Climate change threatens the water supply of nations around the world. But it’s difficult to measure whether a region has sufficient water to satisfy the people who live there. Could satellites help?
