YES2 given green light for launch

26.06.2007
After 5 years of design and development work and preparation of the flight model, the second Young Engineers Satellite (YES2) experiment has passed its Final Acceptance Review and been given the green light by ESA for launch in September.

Following four and a half months of assembly, integration and testing at ESTEC, the groundbreaking student experiment was shipped to TsSKB-Progress in Samara, Russia, on 7 May. After a month in storage, a series of final adjustments began on 12 June. Two days later, the experiment was installed for the first time on the exterior of the Foton-M3 spacecraft on which it will piggyback a ride into orbit.

In the coming weeks, YES2 will undergo a series of checks to ensure that all of its systems are functioning as intended in conjunction with Foton. These assessments will include communications tests to ensure that commands can be received via the Foton, electrical interface tests and combined functional tests with all the other Foton experiments.

“Although there were tight deadlines to meet, the students worked closely in conjunction with ESA and prime contractor Delta-Utec to bring the tethered re-entry capsule experiment to a state of readiness for launch,” said Roger Walker, Project Manager for YES2, from the ESA Education Office. “The experiment has completed an intensive verification campaign, involving vibration testing, thermal-vacuum and electromagnetic testing. The team has achieved a great deal to get this far, and the students have benefited tremendously from this practical experience with a real space project.”

One of the most challenging aspects of the mission is the deployment of the unique 30 km tether, which will be the longest ever deployed in space. Until recently, the flight tether was still on the premises of Delta-Utec in order to assess its physical properties and ensure that there will be no snags during deployment. The careful unwinding and winding of the tether alone takes a number of days to complete.

Following the completion of the Final Acceptance Review on 20 June and the YES2 - Foton interface and functional tests on 21 June, the experiment is scheduled to be detached from the main spacecraft and then shipped to Baikonur Cosmodrome in early July. YES2 will be reinstalled on the Foton at the end of July and final checks performed in readiness for the launch campaign during September.

Almost 500 students from most ESA Member States, together with the United States, Japan, Canada and Australia have worked on YES2. Although these were mainly involved in the preliminary design phase, some 60 students have participated in the latter stages of developing and building hardware and software.

Im Focus: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....

Im Focus: Chemical reactions in the light of ultrashort X-ray pulses from free-electron lasers

Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.

Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
