The craft is to remain on the ground during the Titan nights, which last about eight Earth days or 192 hours. [3] Activities during the night may include sample collection and analysis, seismological studies like diagnosing wave activity on the northern hydrocarbon seas, [ 45 ] meteorological monitoring, and local microscopic imaging using LED ...
Huygens (/ ˈ h ɔɪ ɡ ən z / HOY-gənz) was an atmospheric entry robotic space probe that landed successfully on Saturn's moon Titan in 2005. Built and operated by the European Space Agency (ESA), launched by NASA, it was part of the Cassini–Huygens mission and became the first spacecraft to land on Titan and the farthest landing from Earth a spacecraft has ever made.

Huygens was an atmospheric probe that touched down on Titan on January 14, 2005, [114] discovering that many of its surface features seem to have been formed by fluids at some point in the past. [115] Titan is the most distant body from Earth to have a space probe land on its surface. [116]
Together, the three spacecraft will fly behind Earth as it orbits the sun, about 50 million kilometers (31 million miles) from our planet. The agency expects the mission to last four years, with ...
The term "comparative planetology" was coined by George Gamow, who reasoned that to fully understand our own planet, we must study others. Poldervaart focused on the Moon, stating "An adequate picture of this original planet and its development to the present earth is of great significance, is in fact the ultimate goal of geology as the science leading to knowledge and understanding of earth's ...
The first successful flyby Venus probe was the American Mariner 2 spacecraft, which flew past Venus in 1962, coming within 35,000 km. A modified Ranger Moon probe, it established that Venus has practically no intrinsic magnetic field and measured the temperature of the planet's atmosphere to be approximately 500 °C (773 K; 932 °F). [19]
During each orbit, the space probe captured radar data while the spacecraft was closest to the surface, and then transmitted it back to Earth as it moved away from Venus. This maneuver required extensive use of the reaction wheels to rotate the spacecraft as it imaged the surface for 37-minutes and as it pointed toward Earth for two hours.
NASA's Cassini spacecraft, which explored Saturn and its icy moons, including the majestic Titan, ended its mission with a death plunge into the giant ringed planet in 2017.
