Quantum algorithms exploit superposition and entanglement to perform tasks that can outstrip classical methods in specific domains. At the core lies the class BQP ...

How do you measure the pose—that is the 3-D rotation and 3-D translation—of a piece of space junk so that a grasping satellite can capture it in real time in order to successfully remove it from Earth ...

Space junk: a computer-generated image of objects in Earth orbit that are currently being tracked. Approximately 95% of the objects are orbital debris, rather than functioning satellites. (Courtesy: ...

Imagine the explosive disturbance caused by a jet going supersonic. A similar shock wave occurs when subatomic particles known as "solar wind" flow from the sun and strike the Earth's magnetic field.

Aldoria and Look Up Space, two French startups offering space surveillance services, are developing artificial intelligence (AI) algorithms to draw useful information from vast amounts of data. As low ...
