Addressing the challenges faced by the Euclid mission and its users
Euclid, launched in 2023, is a cosmology mission from the European Space Agency (ESA) space program that will conduct an unparalleled massive imaging and spectroscopic survey covering 1/3rd of the sky.
In this talk, I will start with a brief overview of the mission and its scientific objectives. I will then describe the challenges we are facing for the distribution of its scientific data to the members of the Euclid Consortium and, more generally, to the scientific community. In this context, I will present the Euclid Data Space (EDS) project, that brings together the ESA Euclid scientific archive and the ESA Datalabs scientific platform to respond to these challenges. | |

The Roman Space Telescope: Data Management Challenges & Solutions |
|
<
< |
The Nancy Grace Roman Space Telescope is on track for launch in late 2026. The wide-field instrument (WFI) is capable of surveying the sky in the near-infrared more than 1000 times faster than Hubble, with similar spatial resolution. Key science goals include conducting a census of exoplanets via gravitational microlensing and constraining cosmology via weak lensing, baryon acoustic oscillations and high-redshift supernovae. The same observations will be useful for a wide range of astrophysics. An additional 25% of the time in core 5-year mission will be allocated through peer review. Among the key data-management challenges are the high data volume, stringent calibration requirements, a distributed ground system, the need to produce high-level products, and the desire to offer the community computational resources with high-bandwidth access to the data products. | | Anastasia Laity (IPAC) - remote | |

SPHEREx and the VO at IRSA
<--StartFragment--> IRSA's goal in developing the SPHEREx archive is to use VO protocols and models as much as possible. While this has simplified some things, it's not without challenges - we'll discuss what went well and what's been a struggle.<--EndFragment--> |

The COSI gamma-ray telescope: Data management challenges
The Compton Spectrometer and Imager (COSI) is a NASA Small Explorer (SMEX) satellite mission scheduled for launch in 2027. COSI is a wide-field Compton telescope designed to survey the entire gamma-ray sky at 0.2-5 MeV with excellent energy resolution, providing powerful observations of sources with gamma-ray emission lines. In this presentation, we will present an overview of the COSI mission, an introduction to some of the major data challenges with a modern Compton telescope, and a discussion of the plan to align with data standards. |

For missions already launched
For mission in development/to be launched:
- Brief overview of mission
- What are the major data challenges that you foresee: data size, archive, users?
- Are you considering data standards and aligning with IVOA?
