Astrophysics and Science

Universe Exploration

SATLANTIS aims to provide scientific satellites & optical payloads for astrophysics missions, as well as orbiting other celestial bodies apart from Earth, such as Mars or the Moon.

Space Observation Technology - Key features

Fine Guidance System: For a stable tracking on long exposure observations. 
Multiband & Spectroscopy from Ultraviolet to Near Infrared. 
Diffraction limited optics. 
High precision, robust and light-alloy quasi-athermal structure. Operation at cryogenic temperature for low thermal emission in infrared observations 
Simultaneous observations in various bands with dual channel configuration + dichroic/notch filters. 

Our Universe Exploration

iSIM cameras were initially born to observe the stars and, as payloads, on top of observing the Earth, SATLANTIS optical technology, onboard the satellites solutions can be applied to the Universe exploration, detecting light.

iSIM technology was originally designed for astrophysics

Support to SCIENCE

SATLANTIS’ collaborative approach to the scientific community and its technology result in an efficient support to the Astrophysics studies and to a practical application of the knowledge ➡ the NewSpace approach to science is a more flexible and cost effective way to help scientists advance in their research; yet creating synergy and complementarity between New & Traditional Space approach.

Astrophysics Mission


The “Analysis of Resolved Remnants of Accreted galaxies as a Key Instrument for Halo Surveys” (ARRAKIHS) is  European Space Agency (ESA) science programme mission will study dark matter in the Universe through an international consortium led by Spain.

Satlantis is the Instrument Prime, responsible for the design, assembly, integration, and qualification of the payload, in collaboration with a European international consortium.

The Payload is the brain of ARRAKIHS, an instrument composed of two visible cameras and two infrared cameras developed by SATLANTIS.

On November 2, 2022, ARRAKIHS has been selected as ESA’s next Fast mission (F-class) in ESA’s Science Programme. 

In May 2024 the Payload/Instrument Phase A (iPRR) was completed. 

Phase B consist of the approval of the Instrument Preliminary Design Review (iPDR),  for the first half of 2026.

The estimated launch is in 2030.
