In connection with Germany's sanctions against Russia, Roscosmos Director General Dmitry Rogozin sent a letter to Anke Kaiser-Pitzal, chair of the board of the German Aerospace Center (DLR), about the termination of joint scientific experiments on the International Space Station.

"The announced termination of cooperation with the Russian Federation by the leadership of the Federal Republic of Germany in the field of higher education, scientific research and professional training is certainly causing irreparable damage to the existing long-standing cooperative ties and significantly hinders activities in the field of space exploration for peaceful purposes," Dmitry Rogozin said in the letter.

According to him, the unfriendly and destructive actions of DLR aimed at curtailing joint space projects, including the shutdown of the German eROSITA telescope at the Russian Spektr-RG space observatory, led to the disruption of a unique scientific program to build a map of the entire sky in the X-ray spectrum.

"In this connection, I consider it impossible for further cooperation between Roscosmos and the German Aerospace Center to implement joint space experiments on the International Space Station, including the experiments Uragan, Matryoshka-R, Vampir, and Ecoplasm," stated Dmitry Rogozin.

• The Uragan experiment is dedicated to development of ground-space system for monitoring and forecasting of natural and man-made disasters.
• The Matryoshka-R experiment examines the dynamics of the radiation situation along the ISS flight path and in its compartments and the accumulation of dose in an anthropomorphic phantom placed inside and outside the station.
• Vampir experiment implies crystals of CdZnTe solid solutions grown by moving solvent zone in a rotating magnetic field.
• The Ecoplasm experiment is designed for kinetic studies of fundamental classical processes in condensed matter using large three-dimensional complex plasma systems.

The Russian program of these experiments will be carried out in full without the participation of the German side. All released resources will be used to implement space experiments on the ISS in the interests of Russian organizations.
