How can space debris to be disposed of quickly? What is space weather? On 9 May 2013 started at 6.00 clock CEST from Esrange Space Center in Kiruna, Sweden, REXUS-13 research rocket with four student experiments aboard to clarify these and other issues. The nurse rocket REXUS 14 was already m6 linebacker two days earlier, on 7 May lifted at 6.00 clock CEST. The double campaign, around 50 students from Germany, Sweden, Great Britain, Switzerland and Hungary participated in the with their self-designed and built experiments, is part of the student program REXUS / BEXUS of the German Aerospace Center (DLR) and the Swedish Space Agency SNSB.
The flight time of almost six meters long single-stage rocket of the type "Improved Orion" lasted from the ignition until the landing of the payload around ten minutes. They reached this heights of about 83 (REXUS 13) and 82 (REXUS 14) kilometers, so the edge of space. m6 linebacker
After the end of their lifetime satellite to be abandoned. As a space "garbage" They live then their existence in the universe and provide a collision hazard for active space vehicles constitutes Both teams Space Sailors m6 linebacker of the RWTH Aachen and Strathsat-R Strathclyde University (UK) have been thinking about how this space debris to be disposed of quickly can. Due to the deceleration by the "residual atmosphere" includes the discarded satellites back to Earth, where they burn up in the atmosphere. The process will take depends on the height of its orbit for many years. For their approach, the students have made the following circumstance to benefit: If the cross section of the satellite increases, it increases the braking effect, and the descent is faster. Therefore, the students test on REXUS on microsatellites - cubes with an edge length of ten centimeters - how to under space conditions different types of umbrellas or sails unfold from the satellite.
The students of CERESS teams Munich Technical University have analyzed and found that many of experiment functions are needed again and again the REXUS experiments of their predecessors. These include a regulated power supply, data storage, management and control of the experiment, real-time communication as well as a standard connection to the missile system and to the ground. In addition, often real-time images, acceleration data, temperature and pressure values are needed by the flight. The students therefore have a platform with these functions built, which is now being tested during m6 linebacker the flight and subsequent teams will allow a greater focus on the actual experiment.
With the SOLAR experiment, the students of the Technical University of Luleå, Sweden aim to improve the repair options on space missions. Your experiment will prove that no quality reducing gas pockets (cavities) are left in weightlessness in the solder joints when soldering is done at low pressure. m6 linebacker The students will analyze the solder joints after the return of the experiment m6 linebacker exactly under X-rays.
In a tank, the fuel collected on the bottom due to gravity, and enters therein via the tank outlet m6 linebacker and the fuel line to the engine. In microgravity, however, are formed in the liquid bubbles as soon as the tank is not completely filled. m6 linebacker These can then be put before the discharge and interrupt the fuel supply. Due to the surface tension of the fuel, however, it can be held in place by a lamellar m6 linebacker structure at the bottom of a tank, as in a sponge. The CAESAR team from the University of Applied Sciences Western Switzerland, has set four such "sponges" with radial fins on a centrifuge. They are filled with different amounts of liquid and rotated at four different, small accelerations. The students watch with cameras such as the fluids behave under these conditions between the slats. With the experimental data, the students want to check theoretical approaches and help to improve the structure of fuel tanks for space
MUSCAT The team from the Royal Institute of Technology (KTH), Sweden, is testing a new way of measuring. During the flight of four probes from the spherical missile released, that are equipped m6 linebacker with GPS. From the position data which are measured during the free fall, the temperatures in the atmosphere at several points may be determined at the same time in combination with different methods for calculating the fluid mechanics, the air resistance.
