Methane detected at Mars’ Gale Crater (the centre picture).
For the first time, an instrument orbiting Mars and a rover on the surface have detected methane simultaneously – raising hopes for finding life on the red planet.
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?
Scientists conduct research in Hawai'i Volcanoes National Park to practice for Mars landings.
To prepare for future Mars missions, scientists collect samples and simulate communications conditions from volcano parks on Earth.
Artist’s depiction of a moon base with a view of Earth in the distance.
Scientists are figuring out how to reduce the cost of space travel – to and from the Moon and possibly to Mars. One approach is to mine the Moon for resources necessary for interplanetary travel.
Minutes after launching the Falcon Heavy rocket, SpaceX was livestreaming footage from the Tesla Roadster it released into space.
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.
Opportunity in Endurance Crater.
Rovers including 'Rosalind Franklin' will pick up where Opportunity left off – trying to answer the question of whether there is, or ever has been, life on Mars.

Naming features on other worlds is a trickier issue than you might think.
It’s core to life on Earth.
The Earth's core is cooling down, and one day it will be completely solid – when that happens, Earth might look a lot like Mars.
Artist’s impression of InSight after its scientific instruments have been deployed.
From turning on instruments to gathering the first data, the next few months will be busy for Mars scientists.
Signs of life on Mars? These are the tracks of NASA’s Curiosity rover exploring the Martian landscape.
Mars has long captured our imagination, from claims of canals to Martian attacks and now our latest NASA exploration to look inside the red planet.
If you went to Mars, you’d need to be able to survive an extremely punishing environment. This picture, taken by NASA’s Mars Exploration Rover Opportunity, gives you an idea.

I've worked with NASA’s Mars Exploration Rover Project for 16 years. If you got yourself a ticket to Mars, here's how I'd advise you to prepare. And by the way, any mistake could kill you.
Once people get there, Mars will be contaminated with Earth life.

NASA's InSight Mars lander touches down Nov. 26, part of a careful robotic approach to exploring the red planet. But human exploration of Mars will inevitably introduce Earth life. Are you OK with that?
Mars seen by the Viking orbiter.
There's enough dissolved oxygen in the salty lake below Mars' surface to support simple lifeforms such as sponges. Here's what that means for space exploration.
Enjoying the planets lined up in a row.
The five planets visible to the naked eye since ancient times are putting on a dazzling display this month, in a night-sky dance along with the Moon.
The south polar cap of Mars is hiding a subsurface lake, according to new research.
Studies from our own planet shed light on whether there could be life in a subglacial lake on Mars.
The moon is our closest neighbour and our best hope for building capacity to explore space.

Could Canadian technology play a part in the newly announced U.S. Space Force? A team at McMaster University has developed an instrument that could keep Space Force troops safe from radiation.
Earth experiences constant volcanic activity - here’s Indonesia’s Mount Anak Krakatau (Child of Krakatoa) photographed in July 2018.
Compared to Earth, more "oomph" is required to bring magma to the surface of Mars, and this is probably why we haven't seen any recent eruptions on the red planet.

Augmented reality technology could help recreate familiar sensory experiences from Earth.
Pie in the sky? Mars Ice Home concept.
Elon Musk may be disappointed by recent studies threatening his plans to go to Mars, but planetary scientists are breathing a sigh of relief.
