Extreme velocities and temperatures makes the return flight to Earth the most perilous part of a space mission.
A new country launches a mission to Mars. A space expert explains what this means for the Middle East and the African continent.
Why are scientists trying to grow organs at the International Space Station? People live on Earth not in zero-gravity. A stem cell expert explains why it is useful to do these experiments in space.
How do people in a special airplane flight get to float like there is no gravity – just like astronauts? An aerospace engineer explains.
The distance between the ISS and Earth is the same as about 3,850 football fields. To bring the station down, rockets will lower it a bit, and then gravity will send it crashing the rest of the way.
About 770 Australian entities are already developing space-related infrastructure, most of which are privately owned.
To intercept the ISS, the capsule must match the station’s speed, altitude and inclination.
SpaceX's launch of astronauts to the International Space Station will make it the first private company to launch humans to space. The effort has ramifications for NASA and spaceflight in general.
Female astronauts may be better off avoiding combined hormonal contraceptive pills to control their periods in space, according to new research.
Two defunct satellites passed within metres of one another, prompting renewed focus on the dangers of space debris. But with many satellites treated as military secrets, how do we track the hazards?
The International Space Station is the biggest human made structure in space and the third brightest object in the sky. But the living conditions for the six astronauts on it are quite cramped.

Before sending humans to Mars or the moon, scientists need to understand what long-term space living does to the human body. Now results are coming in from the Kelly brothers in the TWINS Study,
As commercial spaceflight companies lower the cost of reaching space, nations can launch more missions. But while astronauts are great for whipping up enthusiasm, is a manned mission worth the cost?
If SpaceX wants to take humans to the International Space Station and beyond it must pull off a safe landing of its Dragon capsule.
SpaceX's advances in space technology have reduced barriers to space and changed the direction of American space policy, but it is not without its challenges.
A brief line in the State of the Union address hints at an exciting year for commercial spaceflight companies in the US. After an eight year lull, US rockets will again carry astronauts into space.
