The Dragon

dragon concerned is a cargo ship built by the SpaceX company. Yesterday, we spit fire and replace Cape Canaveral, Florida, bound to the International Space Station. Firstly, scheduled for 26 April, the ejection was delayed a few times for all sorts of reasons, including mechanical bias affecting the station's power system. The re-delivery of the Space Station by cargo vessels is essential and sensitive operations that are subject to much planning.

After doing several times around the Earth, the ship dragon synchronize its orbit with some International Space Station. Tomorrow, about 7 am, it should be about 500 meters from the station, flying on its side at 28,000 km / h, like it. That's when David Saint-Jacques will try to catch the ship with the famous Canadian Army. Quebec astronaut took part in a cargo ship caught two weeks ago with American colleague Anne McClain, but this is the first time she will be directly responsible. He is assisted by his American colleague Nick Hague. "The scratch of a cargo ship is a time when the astronaut is responsible for his actions alone," David Saint-Jacques had already told him during a training session at NASA's Houston facility. The control center helps to get to the capsule. But at some point, you have to catch it and hold it. "

The robot

During all the movements, Canardam 2 will be the work instrument of David Saint-Jacques, the second version of the Canadian Branch. The robotic arm was originally designed to build the International Space Station, but later realized that it could be used to hold cargo ships. Astronauts spend a lot of their training on the ground practicing these catches. Tomorrow, David Saint-Jacques will have to take care not to let the load ship fill with precious goods, ensuring that the station is not shattered, which could result in very serious consequences.

Tomato seeds

In addition to the various equipment and meals usually found in the supply ships, the capsule dragon this time will bring more unusual goods: 1.2 million tomato seeds. These are sent to the space as part of a project called Tomatosphere. After four weeks of pressure, the seeds will return to Earth on the same ship dragonthen it will be distributed to 20,000 classes in Canada and the United States. Students grow these “space” tomatoes alongside common tomatoes, without knowing which ones are. They then record their observations to describe the possible effects of space on the seeds. The issues surrounding growing plants in space are essential for future long-term journeys, such as those designed for Mars, when it is impossible to bring all the food. necessary on the board. Plants growing would feed astronauts in oxygen production and eliminate CO2.
