The Gran Telescopio Canarias (GTC) is located on the Canary Islands, Spain.

The GTC has a primary mirror diameter of 10.4 meters, making it one of the largest optical telescopes in the world.

The GTC was first operational in 2007, although it was not fully completed until 2010.

The GTC is used for a wide range of astronomical observations, including studying exoplanets, observing distant galaxies, and searching for dark matter.

The GTC project is a collaboration between Spain, Mexico, and the United States.

CanariCam is the instrument used for adaptive optics on the GTC.

OSIRIS is the instrument used for infrared observations on the GTC.

HARPS-N is the instrument used for high-resolution spectroscopy on the GTC.

GTCAM is the instrument used for imaging and multi-object spectroscopy on the GTC.

The approximate cost of the GTC project was 400 million euros.

Observing the surface of Mars is not a scientific goal of the GTC.

The GTC is located at the Roque de los Muchachos Observatory on the Canary Islands, Spain.

The National Astronomical Observatory of Japan is not a partner institution in the GTC project.

HD 80606 b was the first exoplanet discovered using the GTC.

The detection of gravitational waves was not a major scientific discovery made using the GTC.
