Now here is fun topic – space bubbles. Fun and with VERY complicated physics!

ESA: Things got heated on the International Space Station this week after the Multiscale Boiling experiment, known as Rubi, was successfully switched on.

ESA astronaut Luca Parmitano installed the shoe box-sized container studying the boiling process in the Fluid Science Laboratory of the Columbus module after its arrival on a Dragon cargo resupply mission in August.

The experiment is now in full swing and generated its first bubble under controlled conditions.

While the bubbles form, a number of measurements are taken. The temperature sensor in the left of this image measures bubble temperature while a high-speed camera records how the bubbles behave and an infrared camera tracks the temperature of the heated region.

Scientists will also observe and quantify the effect of external forces on the boiling process.

Rubi is equipped with an electrode to assess the effect of the electric field on the bubbles, as well as a small pump that, when activated, will get the liquid moving to evaluate flow on the boiling process.

Why space bubbles?

Scientists are investigating the boiling process in space mainly for two reasons.

Running this experiment ...
