An orange pouch and a yellow cable are paving the way for missions to the moon. By monitoring space radiation and enabling faster communications, the Dosis-3D experiment and the Columbus Ka-band or ColKa terminal, respectively, are providing the insights needed to enable safer missions father out in space.

Orange Dosis-3D pouches are everywhere in the Columbus laboratory on the International Space Station. A series of active and passive dosimeters, they measure space radiation inside the module as well as how it penetrates the Space Station's walls.

Radiation levels in space are up to 15 times higher than on Earth. As soon as humans leave the protective shield that is Earth's atmosphere, space radiation becomes a serious concern.

The Columbus module is monitored by 11 passive dosimeters. The dosimeters are about the size of a pack of playing cards and attach to the walls of Columbus with Velcro. The detectors record how much radiation has been absorbed in total during the period they are in space.

This experiment has been monitoring radiation levels for a number of years and after each six-month crew rotation, the detectors are replaced to record changes in radiation.

The weathering of silicate rocks plays an important role to keep the climate on Earth clement. Scientists led by the University of Bern and the Swiss national center of competence in research (NCCR) PlanetS, investigated the general principles of this process. Their results could influence how we interpret the signals from distant worlds—including such that may hint towards life.

The conditions on Earth are ideal for life. Most places on our planet are neither too hot nor too cold and offer liquid water. These and other requirements for life, however, delicately depend on the right composition of the atmosphere.
