wood in orbit

The first wooden satellite has just been tested at high altitude by three Finnish companies. Made of birch wood, it is expected to be launched at the end of the year by New Zealand company Rocket Lab. The test was carried out using a balloon that reached an altitude of 31 km and then parachuted in mid-June.

This is Elon Musk’s only Quebec project, which includes underground tunnels where the capsules will travel at a speed of 1,100 km / h with cargo and passengers on board. The Polytechnique project is currently in the 3D modeling stage, and a tunnel is planned where it will be tested.

Robot in the sand

American engineers have developed a robot capable of moving in the sand, which could be used on missions to Mars. at robotics science In mid-June, researchers at the University of California described how the 5 cm diameter and 2 meter long robot successfully countered the problems faced by other tunnel-boring robots, reaching a speed of 4.8 m/s. In 2018, the Martian InSight mission relied on a tunnel-boring robot capable of digging 5 meters into the lab, which ultimately didn’t work on the Red Planet.
