ESA chooses three scientific missions for further study

ESA chooses three scientific missions for further study
ESA Portal - 2010 Feb 19
Dark energy, habitable planets around other stars, and the mysterious nature of our own Sun, have been chosen by ESA as candidates for two medium-class missions to be launched no earlier than 2017.

On Thursday 18 February, ESA’s Science Programme Committee (SPC) approved three missions to enter the so-called definition phase. This is the next step required before the final decision is taken as to which missions are implemented. The three proposals chosen to proceed are Euclid, PLAnetary Transits and Oscillations of stars (PLATO), and Solar Orbiter.

Euclid would address key questions relevant to fundamental physics and cosmology, namely the nature of the mysterious dark energy and dark matter. Astronomers are now convinced that these substances dominate ordinary matter. Euclid would map the distribution of galaxies to reveal the underlying ‘dark’ architecture of the Universe.

The PLATO mission would address one of the most timely and long-standing questions in science, namely the frequency of planets around other stars. This would include terrestrial planets in a star’s habitable zone, so-called Earth-analogues. In addition, PLATO would probe stellar interiors by detecting the gaseous waves rippling their surfaces.

Solar Orbiter would take the closest look at our Sun yet possible, approaching to just 62 solar radii. It would deliver images and data that include views of the Sun's polar regions and the solar far side when it is not visible from Earth.

ESA's Tough Choice: Dark Matter, Sun Close Flyby, Exoplanets (Pick Two)
Universe Today - 2010 Feb 20
Key questions relevant to fundamental physics and cosmology, namely the nature of the mysterious dark energy and dark matter (Euclid); the frequency of exoplanets around other stars, including Earth-analogs (PLATO); take the closest look at our Sun yet possible, approaching to just 62 solar radii (Solar Orbiter) … but only two! What would be your picks?

At least of the three, they get to choose two. They couldn't afford even one if they had to pay Carbon Credits.
