Mission Euclid gibt neuartige Einblicke in Tiefen des Weltalls

Die Mission Euclid der Europäischen Weltraumorganisation ESA konnte heute eine große Menge neuer wissenschaftlicher Daten liefern. Die Deutsche Raumfahrtagentur im Deutschen Zentrum für Luft- und Raumfahrt (DLR) finanziert die sechsjährige Mission mit Mitteln des Bundesministeriums für Wirtschaft und Klimaschutz (BMWK) als größter Beitragszahler.

In our second blogpost we give an intro into the three #ESAEuclid instrument reference papers. They will also function as a reference for the next years: What can the #VIS and #NISP instruments do (and what can they not do), what was the design background and the underlying requirements? And how do we calibrate these data?

Here's our intro:

Another of our papers in the #ESAEuclid / @ec_euclid overview series of 5, supplementing the #NISP paper above, was already accepted last week:

Euclid. IV. The NISP Calibration Unit

The near-infrared calibration unit (NI-CU) on board Euclid's Near-Infrared Spectrometer and Photometer (NISP) is the first astronomical calibration lamp based on light-emitting diodes (LEDs) to be operated in space. Euclid is a mission in ESA's Cosmic Vision 2015-2025 framework, to explore the dark universe and provide a next-level characterisation of the nature of gravitation, dark matter, and dark energy. Calibrating photometric and spectrometric measurements of galaxies to better than 1.5% accuracy in a survey homogeneously mapping ~14000 deg^2 of extragalactic sky requires a very detailed characterisation of near-infrared (NIR) detector properties, as well their constant monitoring in flight. To cover two of the main contributions - relative pixel-to-pixel sensitivity and non-linearity characteristics - as well as support other calibration activities, NI-CU was designed to provide spatially approximately homogeneous (<12% variations) and temporally stable illumination (0.1%-0.2% over 1200s) over the NISP detector plane, with minimal power consumption and energy dissipation. NI-CU is covers the spectral range ~[900,1900] nm - at cryo-operating temperature - at 5 fixed independent wavelengths to capture wavelength-dependent behaviour of the detectors, with fluence over a dynamic range of >=100 from ~15 ph s^-1 pixel^-1 to >1500 ph s^-1 pixel^-1. For this functionality, NI-CU is based on LEDs. We describe the rationale behind the decision and design process, describe the challenges in sourcing the right LEDs, as well as the qualification process and lessons learned. We also provide a description of the completed NI-CU, its capabilities and performance as well as its limits. NI-CU has been integrated into NISP and the Euclid satellite, and since Euclid's launch in July 2023 has started supporting survey operations.

#Stunning #pictures released today by the #European #Space Agency of #galaxies and a globular cluster.

No, these #images are not from #JWST nor #HST, but from #ESA's newest mission: #Euclid.

These images are combining data from the 2 instruments onboard: VIS, and #NISP that was build at #LAM.

Enjoy ! 🤩

Another feature that you can see in #ESAEuclid's first images: What are these? Satellite streaks 🛰️? Asteroids ☄️? Superwoman (or Superman) 🦸🏽 ?

No, much smaller: these are traces by #CosmicRays ⚡, hitting #Euclid's #VIS and #NISP detectors directly, depositing energy and electric charges in their pixels.
