Hydrogen cars were heralded as an avenue towards universal green motoring, but progress has stalled in recent years.
Tracking CO2 emissions with satellites can help to support emission reduction efforts under the Paris Agreement.
After its fourth delay, the Artemis 1 launch is now scheduled for Nov. 16, 2022. NASA has a history of missing launch deadlines, but the private sector is slowly making launches more reliable.
Sophisticated equipment on the Perseverance rover is helping answer some of the many questions researchers have about Mars’ geology over time.
The technology of an advanced alien civilization is likely to produce many signs that could be detected across the vastness of space. Two astronomers explain the search for technosignatures.
If history is any indication, space exploration will need to contend with and prevent sexual harassment and assault during missions and training.
The Double Asteroid Redirection Test successfully showed that it is possible to crash a spacecraft into a small asteroid and change its orbit. This technique could save Earth from asteroids in the future.
Scientists have uncovered the long-term history of our receding moon. And it’s not from studying the moon itself, but from reading signals in ancient layers of rock on Earth.
In some African countries, astronomical research is quite developed.
As the potential for space travel increases, it is necessary to develop methods to protect astronauts from environmental stresses in space. Studying the DNA of baker’s yeast may provide some clues.
The Double Asteroid Redirection Test successfully showed that it is possible to crash a spacecraft into a small asteroid. Whether the approach could save Earth from a future threat remains to be seen.
Crashing the 1,340-pound DART probe into the small moonlet orbiting the asteroid Didymos should redirect its trajectory – and could be a model for how to save Earth in the future.
Newly discovered super-Earths add to the list of planets around other stars that offer the best chance of finding life. An astronomer explains what makes these super-Earths such excellent candidates.
Lunar mining and geopolitical squabbles are set to play key roles in humanity’s return to the Moon.
When the Orion Crew Capsule orbits the Moon there will be no one on board. But the mission will mark a key step in bringing humans back to Earth’s dusty sidekick.
The era of lunar resource use is quickly approaching. But with legal and practical issues still looming, nations are starting to think about sustainable ways to mine and protect the Moon.
An astrophysicist explains what wormholes are and how these theoretical space-time tunnels have popped up in the solutions to a set of decadesold equations.
A new publication clarifies how existing legal frameworks apply to space exploration and development. The McGill Manual also highlights the catastrophic implications of conflict in space.
Listening for events like black hole collisions is important in astronomy research – and the technology is only getting better.
