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.
Russia’s testing of an anti-satellite weapon risked the life of astronauts on the International Space Station and could have astronomical impacts on Earth.
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.
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.
International space law doesn’t explicitly prohibit anti-satellite missile tests — which makes uproar over Russia’s actions all the more significant.
A close call for the International Space Station highlights the growing problem of space junk putting satellites at risk.
Satellite imagery can help to get data in fragile, crisis-affected situations.
New technologies can help reduce the cost of producing maps that warn where floods might happen.
The CUAVA-1 cubesat will monitor space weather and changes to Earth’s ionosphere that affect satellites and electronics.
Did we observe the most distant gamma ray burst yet seen, or was it something closer to home?
What did Mercury look like as BepiColombo swung by?
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.
An expert says Nigeria’s capacity to access space support for development and security will be affected if its satellite goes down.
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.
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.
New results show why and how water is disappearing from Mars atmosphere.
Earth observation satellites can measure millimetre changes in sea level and track deforestation in near-real time.
