With the arrival of Cosmic Girl in Cornwall, the UK is preparing for its first rocket launch.
Artificial intelligence can spot differences in images from before and after a storm over wide areas in almost real time. It showed Hurricane Ian’s vast damage in Florida.
In some African countries, astronomical research is quite developed.
In Western Australia, the first of a series of little satellites just burned up in the sky – exactly as planned.
The Double Asteroid Redirection Test successfully showed that it is possible to crash a spacecraft into a small asteroid. Whether the approach could save Earth from a future threat remains to be seen.
Satellite telemetry, tiny geolocation tags and passive acoustic recording are providing new insights into bird migration and vital data for conservation.
Private satellite companies have boomed in recent years, and many experts have wondered what role they would play in a conflict. They have proved to be invaluable to Ukraine in recent months.
Build a powerful enough laser, and you can shine it into space. Aim it well, and you can blind satellites.
The southern hemisphere is more likely to be hit by space debris than the northern one.
With decades of images and data from the same locations, these satellites can show changes over time, including deforestation, changes in waterways and how loss of trees corresponds to urban heat.
The Met Office issued its heatwave warning six days before the mercury peaked – potentially saving many lives.
Technologies being developed for growing food in space have contributed to advances in agriculture and crops on Earth.
Extreme heat waves are putting lives in danger, with some of the hottest urban neighborhoods 10 degrees hotter or more than their wealthier neighbors. Often, these are communities of color.
Current trends suggest that powerful nations are defining the rules of resource use in space and satellite access in ways that will make it hard for developing nations to ever catch up.
When Indigenous peoples lose their river flow to dams, satellite programs like Landsat – which is celebrating its 50th anniversary – can help them fight for their resources.
Anti-satellite weapons could fill Earth’s orbit with space junk and make it unusable for military and civilian purposes
Africa’s outer space programme can help the continent meet its other flagship goals.
Shrinking satellites are making it cheaper and more accessible to do science in space.
The future of Australia’s space efforts will hinge on coordination between defence, industry and universities.
