ESA's Integral gamma-ray gazer gasps its last.

After almost 23 years on the job, European Space Agency's (ESA) International Gamma-Ray Astrophysics Laboratory (Integral) is set to make its final observations.

🛰️🔭✨ Ce 28 février, après 2 886 orbites et 22 ans dans l'espace, d'observations, le télescope gamma #Integral de l'ESA a cessé de collecter des données scientifiques.
Integral a joué un rôle essentiel dans la compréhension des sursauts gamma, des ondes gravitationnelles, etc

[End of mission for #Integral] At the time of its launch (in 2002), it was the most advanced #gamma-ray observatory and the first space observatory capable of simultaneously viewing celestial objects in the gamma, X-ray and visible domains.

Integral has transformed our understanding of the high-energy #Universe. Its observations have made it possible to identify the sources of the so-called “long” and “short” gamma-ray bursts (#GRB) : the collapse of stars into supernovae, on the one hand, and the collisions of black holes and neutron stars, on the other.

IRAP's scientific and technical staff have contributed to the success of this mission: both in the realization of the #instruments and in the analysis of the observation data. On February 28, 2025, a long and beautiful page of our space adventure turns ...

[Fin de mission pour #Integral] Au moment de son lancement (en 2002), il était l' #observatoire de rayons #gamma le plus avancé et le premier observatoire spatial capable de voir simultanément des objets célestes dans les domaines gamma, X et visible.

Integral a transformé notre compréhension de l’ #Univers des hautes énergies. Ses observations ont notamment permis d'identifier les sources des #SursautsGamma qualifiés de "longs" et "courts" : l'effondrement d'étoiles en supernovae, d'une part, les collisions de trous noirs et d'étoiles à neutrons, d'autre part.

Les personnels scientifiques et techniques de l'IRAP ont contribué au succès de cette mission : tant à la réalisation des #instruments qu'à l'analyse des données d'observations. Ce 28 février 2025, une longue et belle page de notre aventure spatiale se tourne ...

Right, I thought it was not, that's why no luck.

I realize the components are not all off-the-shelf, but not every single piece is reinvented every time. Even the platform can be re-used, like between #XMM-Newton and #INTEGRAL.

Aperture doors exist in many X-ray satellites: #XMM-Newton, #Chandra. I suppose they are somehow different?

There is a whole systems engineering work to reduce the chance of issues like this.

ZenodoX-Ray Observation of Venus with the INTEGRAL TelescopeX-Ray observation of Venus using JEMX instrument on INTEGRAL telescope in the 18.04.22 to 24.04.22 window. Abstract: On April 22 and 24, 2022, Venus was observed with the JEM-X detector of the INTEGRAL space telescope. The observation performed yielded a discussed positive observation of the planet using three different modelling methods of the incoming flux of the source. All yielded a positive average flux at the 3σ level. No evidence of correlation between the solar and venusian flux variability was found. A very solar flare and CME direction locator was tested and its limits quickly found because of the limited FoV of the satellites contributing to these events’ coordinates in the HEK database. This report suggests that the solar system planets can be studied using the available INTEGRAL data gathered over the last 19 years.
