The now defunct Infrared Astronomical Telescope was one of the satellites involved in the near-collision.
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 ISS is a collaboration between the space agencies of Canada, Russia, Japan, Europe and the United States.
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.
Was the International Space Station the scene of space’s first crime?
NASA is reportedly investigating the first alleged crime in space. But criminal jurisdiction aboard the International Space Station is much more straightforward than it would be for space tourists.
The fifth episode of the To the moon and beyond podcast series explores where we will be travelling in 2069.
People do live outside Earth – on the International Space Station! But humans have had to find a way to make the conditions there more like what we’re used to at home.

The short answer is yes, but it’s really, really difficult.
Canada’s involvement - beyond the Canadarm 3 -in lunar exploration and development is crucial.
Compared to other governments' support of lunar business and technology, Canada needs to be more strategic and active in lunar exploration or we will be left behind.
Are space twin Scott and Earth twin Mark no longer identical?
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,
What makes more sense: Sending a human or a robot to Mars?
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?
The SpaceX Crew Dragon is docked to the International Space Station.
If SpaceX wants to take humans to the International Space Station and beyond it must pull off a safe landing of its Dragon capsule.

35 years ago Sally Ride became the first American woman in space. But rather than focus on her own extraordinary achievements, her passion became boosting the number of girls pursuing STEM. Another pioneering astronaut remembers her friend and colleague.
Small satellites are launched to Low Earth Orbit - and then eventually burn up.
So long as small satellites are in low Earth orbit – and most likely they will be – the Earth's "vacuum cleaner" will clean them up.
The first piece of the International Space Station was launched in 1998.
