Australia’s bushfire response relies on foreign satellites, which are not designed to assess our highly flammable eucalypt-clad landscapes.
The International Space Station is a great example of how space has, for the most part, been a peaceful and collaborative international arena.

Activities in space today are far more numerous and complicated compared to 1967, before humans had landed on the moon or Elon Musk had been born. Two experts explain the need for better laws to keep space peaceful.
Space debris produced by anti-satellite weapons can have dangerous consequences.

A Russian satellite has been destroyed in a missile strike, creating a vast amount of debris that joins the tens of thousands of pieces already in orbit around the Earth.
If a satellite is destroyed, the debris fans out in orbit and poses serious threats to other satellites or crewed spacecraft.

Russia destroyed one of its old satellites during a successful test of an anti-satellite weapon. A space security expert explains what this weapon was and the dangers of the expanding debris field.
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.
