Rubin Observatory Legacy Survey of Space and Time (LSST)

Cerro Pachón ridge, north-central Chile

The goal of the Vera C. Rubin Observatory project is to conduct the 10-year Legacy Survey of Space and Time (LSST), which address four science areas and some of the most pressing questions about the structure and evolution of the universe and the objects in it:
• Understanding Dark Matter and Dark Energy
• Hazardous Asteroids and the Remote Solar System
• The Transient Optical Sky
• The Formation and Structure of the Milky Way

LSST will deliver a 500 petabyte set of images and data products (more than 20 terabytes of data must be processed and stored each night) thanks to its  8.4-meter Simonyi Survey Telescope and camera with more than three billion pixels of solid state detectors camera.

LSST will conduct a deep survey over an enormous area, by taking repeat images of every part of the sky every few nights in multiple bands, or segments of the electromagnetic spectrum, for ten years. 
The astronomical catalogs that will be produced, will enable more projects that will contribute to find answers in the four scientific areas mentioned above.

The scientific challenge

The scientific questions that the Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST) will address are profound:  What is the mysterious dark energy that is driving the acceleration of the cosmic expansion? What is dark matter, how is it distributed, and how do its properties affect the formation of stars, galaxies, and larger structures? How did the Milky Way form, and how has its present configuration been modified by mergers with smaller bodies over cosmic time? What is the nature of the outer regions of the solar system? Is it possible to make a complete inventory of smaller bodies in the solar system, especially the potentially hazardous asteroids that could someday impact the Earth? Are there new exotic and explosive phenomena in the universe that have not yet been discovered?

The Impact

One of ESCAPE main’s goal is to provide a flexible and expandable analysis environment for the astronomy and particle physics communities, which constitute an absolutely essential resource for the big data challenges of the next generation of ESFRIs.
The impact of LSST's partnership with ESCAPE is the more effective use and re-use of existing ESFRI data collections available through the EOSC, new and innovative analysis capabilities at large data rates and scales, and improved training for researchers in deploying their analyses at these scales.
