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.

Gravitational wave kicks monster black hole out of galactic core

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
