The European Space Agency (ESA) launched the Gaia mission in 2013. The mission’s goal is to create the most accurate 3D map of the Milky Way by surveying 1% of the galaxy’s 100 billion stars. The mission is planned to operate for at least five years

The Gaia satellite is a space telescope located at the L2 Lagrange point. It measures the positions of billions of stars with unprecedented precision. The satellite maps the motions, luminosity, temperature, and composition of more than a thousand million stars

The Gaia mission is generating a vast amount of data, which it sends daily to one of three ground stations: 

• Cebreros in Spain 
• New Norcia in Australia 
• Malargüe in Argentina 

The mission is measuring the positions of all objects brighter than magnitude 15 to an accuracy of 24 microarcseconds. This is comparable to measuring the diameter of a human hair at a distance

What is the purpose of GAIA mission

What is Gaia? Gaia, the Global Astrometric Interferometer for Astrophysics, is a European Space Agency astronomical observatory mission. Its goal is to create the largest, most precise three-dimensional map of the Milky Way by surveying about 1% of the galaxy’s 100 billion stars.

Where is Gaia space craft now

The spacecraft currently operates in a Lissajous orbit around the Sun–Earth L₂Lagrangian point.

What type of space craft is Gaia

Gaia is a European space observatory whose goal is to chart a three-dimensional map of the Milky Way galaxy in order to reveal the composition, formation and evolution of the galaxy

How does Esa use Gaia mapping

Gaia is not just mapping star positions but velocities as well. Astronomers can use these to track a star’s orbital path, then rewind their motions to work out where stars originally came from. By doing this for stars across the Milky Way, it’s possible to reconstruct the history of our Galaxy’s growth

How many stars had Gaia found

Gaia catalogues nearly two thousand million stars, measuring each star’s position and motion 200 times more accurately than Hipparcos, and produces data for 20 000 times more stars than its predecessor. The Gaia mission was approved in 2000 as an ESA Cornerstone mission.

What is the full form of Gaia mission

Gaia, the Global Astrometric Interferometer for Astrophysics, is a European Space Agency astronomical observatory mission.
