The plan to resume operations of the German eROSITA telescope aboard the Spektr-RG space observatory, in conjunction with the Roscosmos program, has been outlined by the agency’s leadership. Dmitry Rogozin, the head of Roscosmos, voiced the intent in a televised interview with the Russia-24 channel, signaling that a strategic restoration of scientific capabilities is on the agenda. He indicated that the necessary directives have already been issued to begin this effort, underscoring a commitment to continued collaboration between Russia and international partners for the advancement of space science.
Rogozin framed the decision as one grounded in scientific value, emphasizing the long-term benefits for astrophysical research and the broader goals of space exploration. The move is presented as part of a broader initiative to sustain and enhance Russian participation in high-profile space missions, while ensuring that critical instruments remain operational to contribute to global scientific knowledge.
In early March, Rashid Sunyaev, who serves as the scientific director of the Spektr-RG project, outlined conditions under which the eROSITA instrument might resume functionality. He stressed that the telescope would become active when geopolitical circumstances permit and when operational safety and international cooperation can be assured. This framing reflects a cautious yet persistent approach to maintaining scientific continuity in a complex international environment.
The Spektr-RG spacecraft itself represents a joint venture that has brought together Russian and German expertise. Developed by the Scientific Production Association named after VI. M. Lavochkina, which is part of Roscosmos, the observatory embodies cross-border collaboration in space science. Germany contributed significantly to the project under the Federal Space Program of the Russian Federation, aligned with directives from the Russian Academy of Sciences. The overall design aims to map high-energy X-ray emissions and provide insights into the structure of the cosmos, including the lifecycle of stars, the behavior of galaxy clusters, and the mechanisms of black holes.
Observers note that the eROSITA telescope has been a cornerstone of the Spektr-RG mission since its inception, offering unprecedented all-sky surveys in the X-ray band. Restoring its operation would enable continued data collection that complements other space-based observatories and ground-based facilities. The decision to reintroduce eROSITA into the mission timeline is framed as a strategic step to preserve scientific momentum and to ensure that crucial datasets remain available to researchers around the world.
