In the past decade, the number of satellites in orbit has skyrocketed thanks to tiny electronics and cheap launches. The crowded night sky is posing problems for astronomers and astronauts.
When conditions are just right in some parts of the Indian Ocean, a type of bacteria will multiply and start to glow. Satellites are helping scientists study these milky seas for the first time.
The Binar-1 mission is the first in a series that will hopefully culminate in a mission to the Moon, with satellites developed using know-how gained from designing tough instruments for the WA outback.
As thousands of new satellites enter Low Earth Orbit, it’s important to consider their potential impact, including possible environmental damage in addition to hindering the work of astronomers.
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.
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.
