The re-entry module of the Foton-M2 spacecraft, which has been in low-Earth orbit for the last 16 days made a successful landing today in an uninhabited area 140 km south-east of the town of Kostanay in Kazakhstan, close to the Russian border at 09:37 Central European Time, 13:37 local time.
The unmanned Foton-M spacecraft, which was launched on 31 May from the Baikonur Cosmodrome in Kazakhstan, carried a European payload of 385 kg covering 39 experiments in fluid physics, biology, crystal growth, meteoritics, radiation dosimetry and exobiology.
All de-orbit to landing procedures went according to plan beginning with the jettison of the Foton-M2 battery module three hours prior to landing. At an altitude of about 300 kilometres, travelling at 7.8 km/s and 30 minutes prior to landing, the retro-rocket situated on the Foton service module was fired for 45 seconds slowing the spacecraft down to reduce its altitude. The Foton-M2 service module was hereafter separated from the re-entry module and, as planned, burnt up in Earth’s atmosphere.

Shape matters when light meets atom

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
