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.
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, 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.
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 impact our lives in many different ways, and some of these may surprise you.
Ten small satellites were launched from 11km above Earth’s surface.
The shift toward mega-constellations is a challenge for global space governance.
