Taking quantum into space
...missions around the globe include the UK-Singapore bilateral collaboration RALspace which will test out an entangled photon source. QEYSSat in Canada will onboard both a WCP source on their microsatellite in collaboration with UK researchers and SMEs...

Interstellar aspirations
... to keep the nanocraft centred in the beam and directed towards the target star within an arcsecond. Small photonic thrusters on the nanocraft would fire continuously to provide course corrections of up to an astronomical unit during its cruise phase...

All of the starlight ever produced calculated by scientists
...the answer seems somewhat unimpressive, the actual number of photons (particles of visible light) behind this dim-sounding ...light is because the Universe is almost incomprehensibly huge and the photons have a lot of room to spread out in. With the...

Quantum-enabled satellite passes key tests
... next big thing in communications, however its use in encryption has been limited to a few hundred kilometres, as the photon can be lost or degraded as it travels through optical fibre channels or terrestrial free space. One way to overcome this...

How to teach and learn about space
.... The second step, of course, was then to test out what his imagination told him on real life photons. Documentaries There's no way to ignore the many documentaries there are which make the science aspects more...

Nuclear Flashlamps in Space
...energetic light in ultraviolet, visible wavelengths, infrared, microwaves, and radio waves, each carried by successively lesser-energy photons. Also neutrons and other subatomic particles. The blast wave of radiation vaporises and ionizes the nuclear...
