Latest Huygens probe Stories
As the Cassini spacecraft reaches the halfway mark in its four-year tour of the Saturn system, discoveries made during the first half of the mission have scientists revved up to find out what's in store for the second act. Cassini has been orbiting Saturn since June 30, 2004, studying the planet, its rings and moons.
An international team of planetary scientists may have solved the mystery of why the atmosphere of Saturn's moon, Titan, is rich in methane.
Recent evidence from the Huygens Probe of the Cassini Mission suggests that Titan, the largest moon orbiting Saturn, is a world where rivers of liquid methane sculpt channels in continents of ice. Surface images even show gravel-sized pieces of water ice that resemble rounded stones lying in a dry riverbed on Earth.
Cassini/Huygens scientists have discovered exactly where on Saturn's largest moon, Titan, the European Space Agency's (ESA) Huygens probe landed last January. Knowing the landing location will allow them to directly compare data from Huygens with remote sensing data from NASA's Cassini orbiter.
By Paul Carrel PARIS (Reuters) - Saturn's moon Titan resembles Earth in many ways but is unlikely to support life, scientists said on Wednesday after almost a year of research into data from the space probe Huygens.
Strong turbulence in the upper atmosphere, a second ionospheric layer and possible lightning were among the surprises found by the Huygens Atmospheric Structure Instrument (HASI) during the descent to Titanâ€™s surface.
Saturn's planet-size moon Titan has dramatic weather, with freezing temperatures, carbon- and nitrogen-rich clouds and possibly lightning, scientists said Wednesday, describing a world that may have looked like Earth before life developed.
Chris McKay, a planetary scientist at NASA Ames Research Center, recently gave a public lecture, sponsored by the Planetary Society, about what scientists have learned about Titan from the Huygens probe. In this, the final part of a four-part series, McKay talks about the unsolved mystery of Titan's ice rocks.
Saturn's moon Titan is notable both because it is the largest moon in our solar system and because it is the only moon in the solar system with a significant atmosphere. Early this year, NASA's Cassini orbiter, currently orbiting Saturn, released the European Space Agency's Huygens probe, which descended through Titan's atmosphere and landed on the moon's surface. Recently, Chris McKay, a planetary research scientist at NASA Ames Research Center, gave a public lecture, sponsored by the...
In this, the second part in a four-part series, McKay talks about Titan's mysterious clouds, some of which are thought to appear only briefly every 15 years.
Cassini-Huygens Mission -- The Cassini unmanned space probe is intended to study Saturn and its moons. It was launched on October 15, 1997 and is estimated to enter Saturn's orbit on July 1, 2004. The mission is a joined NASA/ESA project. Cassini's principal objectives are to: -- determine the three-dimensional structure and dynamical behavior of the rings -- determine the composition of the satellite surfaces and the geological history of each object -- determine the nature and...
Saturn's moon Titan -- Titan is the planet Saturn's largest moon. It is larger than either of the planets Mercury or Pluto and is the second-largest moon in the solar system after Ganymede (it was originally thought to be slightly larger than Ganymede, but recent observations have shown that its thick atmosphere caused overestimation of its diameter). Titan was discovered on March 25, 1655 by the Dutch astronomer Christian Huygens, making it one of the first non-terrestrial moons to be...
