In 2014, wookiemeister & mollwollfumble, with the help of billzilla, will be sending rockets into space. ;-)

The ESA GAIA spacecraft will map the 3-D Milky Way in visible wavelengths for the first time. This is the successor to Hipparcos, the first satellite to precisely determine the distances to nearby stars, GAIA is extraordinarily more powerful than Hipparcos. GAIA was launched 19 Dec 2014, it reached it Sun-Earth Lagrangian point orbit on 8 Jan 2014. It will complete testing and calibration in May 2014.
According to Wikipedia, GAIA has these goals:
Determine the position, distance, and annual proper motion of 1 billion stars with an accuracy of about 20 µas (microarcsecond) at 15 mag, and 200 µas at 20 mag.
Determine the positions of stars at a magnitude of V = 10 down to a precision of 7 millionths of an arcsecond (μas) (this is equivalent to measuring the diameter of a hair from 1000 km away); between 12 and 25 μas down to V = 15, and between 100 and 300 μas to V = 20, depending on the colour of the star.
About 20 million stars will be measured with a distance precision of 1% and about 200 million will be measured to better than 10%. Distances accurate to 10% will be achieved as far away as the Galactic Centre, 30,000 light-years away.
Measure the tangential speed of 40 million stars to a precision of better than 0.5 km/s.
Derive the atmospheric parameters (effective temperature, line-of-sight interstellar extinction, surface gravity, metallicity) for all stars observed, plus some more detailed chemical abundances for targets brighter than V = 15.
Measure the orbits and inclinations of a thousand extrasolar planets accurately, determining their true mass using astrometric planet detection methods.
Detect the bending of starlight by the Sun’s gravitational field, as predicted by Albert Einstein’s General Theory of Relativity, and therefore directly observe the structure of space-time.
Potential to discover Apohele asteroids with orbits that lie between Earth and the Sun, a region that is difficult for Earth-based telescopes to monitor since this region is only visible in the sky during or near the daytime.
Detect up to 500,000 quasars.
