LARES succesfully launched in orbit: satellite and mission description
Antonio Paolozzi, Ignazio Ciufolini

TL;DR
The LARES satellite, launched in 2012, is a passive laser-ranged satellite designed to test Einstein's General Relativity by measuring tiny deviations in its orbit caused by relativistic effects.
Contribution
This paper presents the successful launch, design, and mission objectives of LARES, highlighting its role in testing fundamental physics with unprecedented precision.
Findings
LARES has the highest mean density among known solar system objects.
Preliminary data confirms the satellite's suitability for precise relativistic measurements.
The mission demonstrates effective collaboration between space agencies and universities.
Abstract
On February 13th 2012, the LARES satellite of the Italian Space Agency (ASI) was launched into orbit with the qualification flight of the new VEGA launcher of the European Space Agency (ESA). The payload was released very accurately in the nominal orbit. The name LARES means LAser RElativity Satellite and summarises the objective of the mission and some characteristics of the satellite. It is, in fact, a mission designed to test Einstein's General Relativity Theory (specifically 'frame dragging' and Lense-Thirring effect). The satellite is passive and covered with optical retroreflectors that send back laser pulses to the emitting ground station. This allows accurate positioning of the satellite, which is important for measuring the very small deviations from Galilei-Newton's laws. In 2008, ASI selected the prime industrial contractor for the LARES system with a heavy involvement of the…
