ESO has committed about 20 percent of the cost of the instrument, which is about four million euros, and now requires the commitment of countries in favor of the project and its operation, which are Switzerland, Portugal, Italy and Spain.
funding from those four countries is that Espresso is an initiative of the Geneva Observatory, the National Institute of Astrophysics in Italy, the Port Centre for Astronomy and Astrophysics Institute of Canarias (IAC).
And is that the measurement of velocities of stars is by far, the most successful method to detect planets around other stars. Rafael Rebolo said today it is easy to detect gas giant planets, larger and more massive than the rocky, and recalled that there are several known possible rocky planets around stars that are smaller. According to Rafael Rebolo
with Espresso would be possible to detect planets of a similar size to Earth and sufficiently distant from its star, so that the surface temperatures would be more similar to Earth.
Spain therefore has an interest in the project to go forward, but another thing is how difficult it is to get funding in times of economic crisis like the present.
