ESA's Hipparcos space astrometry mission was a pioneering European project which pinpointed the positions of more than one hundred thousand stars with high precision, and more than one million stars with lesser precision. Launched in August 1989, Hipparcos successfully observed the celestial sphere for 3.5 years before operations ceased in ...
Hipparcos was a scientific satellite of the European Space Agency (ESA), launched in 1989 and operated until 1993. It was the first space experiment devoted to precision astrometry, the accurate measurement of the positions of celestial objects on the sky.
Hipparcos's instruments produced positional surveys of stars. Name: Hipparcos. Launched: August 1989. Status: Completed (1993) Objective: Pinpoint the stars, their motion and distance, this totally European mission mapped the heavens more accurately than ever before. Its work is being refined by ESA's Gaia mission. Mission:
Hipparcos was the first space mission for measuring the positions, distances, motions, brightness and colours of stars. It pinpointed more than 100 000 stars and produced the Hipparcos and Tycho Catalogues, published by ESA in 1997.
28. Mai 2015 · Hipparcos was the first space mission dedicated to measuring the positions, distances, motions, brightness and colors of stars. Learn about the mission objectives, results, legacy and challenges of this pioneering astrometry experiment.
Hipparcos was launched in 1989 and operated until 1993, collecting data on more than 100 000 stars with high precision. It achieved many scientific breakthroughs, such as confirming Einstein's theory of relativity and revealing the shape of the Milky Way.
