ESA's Planck spacecraft on course for safe retirement

In preparation for its final switch-off on 23 October, mission controllers today fired Planck’s thrusters to empty its fuel tanks. The burn is one of the final steps to ensure that Planck ends its hugely successful mission in a permanently safe configuration.

Beyond Planck’s equations

All the objects around us emit thermal radiation. Usually, this radiation can be described very accurately using Planck’s law. If, however, the radiating object is smaller than the thermal wavelength, it behaves according to different rules and cannot emit the energy efficiently.
