The Hubble telescope was built by the United States space agency NASA with contributions from the European Space Agency. The Space Telescope Science Institute (STScI) selects Hubble’s targets and processes the resulting data, while the Goddard Space Flight Center controls the spacecraft. Space telescopes were proposed as early as 1923. Hubble was funded in the 1970s, with a proposed launch in 1983, but the project was beset by technical delays, budget problems, and the Challenger disaster (1986). It was finally launched by Space Shuttle Discovery in 1990, but its main mirror had been ground incorrectly and created a spherical aberration, compromising the telescope’s capabilities. The optics were corrected to their intended quality by a servicing mission in 1993.
After a long and dangerous journey through the space between planets, the Cassini/Huygens Spacecraft reached Saturn on July 1, 2004. On December 25, 2004, the Huygens Probe was purposely liberated from the Cassini Orbiter. Huygens then began its historic descent through the dense blanket of golden-orange fog to at last lift the veil hiding Titan's long-hidden face.
If you have looked away from areas and subjects which are not right and satisfying in your intimate relationship, now is the time to look at it or it will blow up into your face. Ask yourself what it is you might have put under the rug? Maybe you want more commitment in your relationship? Maybe you need more autonomy? Whatever it is now is a good time to be honest and daring to go for your inner vision and dreams. If you don't communicate clearly your desires and needs, you can bet on the outcome of not getting it.
The discovery of a moon can lead to a treasure chest filled with valuable information about the dwarf-planet system. This is because, by measuring the moon's orbit, astronomers can then go on to calculate a mass for the system and gain an important insight into its evolution.
