Methane is a potent greenhouse gas that can leak from oil and gas wells, pipelines and landfills. Satellites can spot the releases fast enough to get them fixed and help protect the climate.

Space exploration is not a waste of resources, but a source of technological and medical advances, a tool for climate monitoring and a source of educational inspiration for youth.
The sky is becoming more cluttered with satellites and space junk. This is affecting astronomical study, but will only have a minor effect — if any — on the viewing of the solar eclipse.
Existing models have over-estimated the role of north Africa as the primary source of global dust emissions for nearly 30 years.

Satellite photography of the Ukrainian city of Bakhmut shows block after block of destroyed buildings. Satellite radar provides a different view – a systematic look at the destruction of the whole city.
Russia isn’t likely to put nuclear missiles in space, but their reported anti-satellite weapon is just as alarming. An expert on nuclear strategy explains.
Telescopes have to contend with light pollution from satellites.

Despite what you may think, Australia has a long history of space activities. But this is the first time the Australian public has been asked its opinions on space.
As the number of satellites in orbit increase, so will the possibilities of space debris. There are currently 8,000 satellites in orbit, but hundreds of thousands more are being proposed.

Countries have submitted applications for hundreds of thousands of new satellites to be launched. The scale poses challenges for overcrowding orbit, with environmental and safety challenges.
Earth’s orbits are getting more and more crowded. To keep track of everything and avoid collisions and catastrophes, we need a new field: space domain awareness.
