The things you learn by going into space and visiting other celestial objects!

The dust on Mars is likely very toxic to human beings. It contains silica, gypsum, perchlorates and nanophase iron oxides, some at toxic levels, and they are are microscopic meaning they likely could migrate into an astronaut's blood stream. Plus the particles are very sharp and pointy so they could easily damage human lungs.

Did you know that how we experience time is not obvious?

In 1962, explorer Michel Siffre descended 130m underground. He had no #time cues with him.
He repeated the exercise several times with other people.

He discovered that with the absence of light, humans adjust to a 48h (instead of 24h) time cycle.

He had been inspired by #space travel & #astronauts confirmed his findings.

His last expedition covered New Year's Eve 2000, but he overslept by 4 days.
