The space missions of the future will need to coordinate multiple satellites and spacecraft − and figure out how to refuel, repair and even replace them in orbit.
Academic rigour, journalistic flair

New techniques are helping forecasters spot potentially dangerous storms earlier than ever.
New US legislation could force Nasa to include enhanced cybersecurity for all its spacecraft.
As the number of satellites and rocket launches increases, so does the amount of discarded rockets and components. This space junk risks falling to Earth, as it did in Saskatchewan this spring.
Sabotaged space stations, falsified space probe data and faked alien contact are just a few of the scenarios a report on space cybersecurity outlines.
Cyberattacks are a growing threat to government and commercial spacecraft.
Satellite data shows the amount of food the residents of the tiny Pacific island have grown over time, pointing to a small but stable population.
Spacecraft exteriors that automatically heal from radiation damage would change the game − one material shows promise.
Burnt-up satellites could dump hundreds of tonnes of aluminium in the stratosphere every year. An atmospheric chemist explains what that might mean
Fears are growing that Russia may be trying to put a nuclear weapon into orbit.
Solar storms can play havoc with electrical grids, satellites and railway lines.
China’s Change'6 is going to explore the Moon’s far side and bring back precious lunar soil for scientists to study.
The amount of space junk will increase as we continue to launch objects into space, but there are ways to curb damage on the ground.
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 Starfish Prime test in 1962 showed how dangerous it would be to detonate a nuclear weapon in space.
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.
New research reveals our understanding of dust’s role in the environment is far from settled.
Powerful jets are launched from the most massive objects in our universe, but we don’t fully understand how. This measurement gets us a step closer to solving the mystery.
Without satellites, we wouldn’t have much of the Earth and climate data we have today. And Australia is a world leader in satellite data.
