INTEGRAL's science operations have been extended by the Science Programme Committee (SPC) up to end 2024. See https://sci.esa.int/web/director-desk/-/extended-life-for-esa-s-science-missions

Given the extension of science operations, ISOC is now starting to prepare the 21st Announcement of Opportunity for observing proposals to be executed in 2024 (AO-21). The milestones will be announced soon.

The next meeting of the INTEGRAL User Group (IUG) will take place on 10/11 May 2023 at ESTEC. The members of the IUG can be found under https://www.cosmos.esa.int/web/integral/teams-iug-members. Feel free to contact any of these colleagues with items you would like to be raised.

To increase the scientific return from its Space Science missions, the European Space Agency welcomes applications from scientists interested in pursuing research projects based on data publicly available in the ESA Space Science Archives. The ESA Archival Research Visitor Programme is open to scientists, at all career levels, affiliated with institutes in ESA Member States and Collaborating States. Early career scientists (within 10 years of the PhD) are particularly encouraged to apply. Applications by and for PhD students are also welcome.

COSI (Compton Spectrometer and Imager ) is a Small Explorer satellite mission sensitive in the 0.2 - 5 MeV range and was recently selected by NASA and scheduled to launch in 2027 (Tomsick et al. 2019). To aid the astrophysics community to become familiar with the COSI data analysis and scientific output, a series of challenges will be launched each year to encourage astrophysicists to analyse sets of data with increasingly more sophisticated tools and a larger range of astrophysical models and simulated sources. The first challenge, funded by NASA’s Astrophysics Research and Analysis (APRA), is already open, and is now publicly available here: https://github.com/cositools/cosi-data-challenge-1.
