Thousands of the satellites orbiting Earth are small – like this cubical satellite seen here being released from the International Space Station.
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.
For centuries, sailors have told tales of milky seas – huge swaths of ocean glowing on dark nights, seen in blue in this false–color satellite image.

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.
Satellite images are critical for security, communication, agriculture and other essential services.

New research suggests that an effective way to locate and track large concentrations of microplastics in the ocean could be from high in the sky.
Megaconstellations threaten to affect the quality of stargazing.
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.

Earth observation satellites can measure millimetre changes in sea level and track deforestation in near-real time.
It’s unlikely falling space junk will destroy property or kill a person.

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, part of which will plummet back to Earth in the coming weeks.
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.
Modern computing allows to spot isolated trees and shrubs in semi-arid areas, facilitating research on the evolution of vegetation cover.
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 affect your life every day.
Satellites impact our lives in many different ways, and some of these may surprise you.

The shift toward mega-constellations is a challenge for global space governance.
A shooting star during the Perseid meteor shower. Soon, thousands of satellites will crowd the night sky.
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.
