On January 14, 2005, a spacecraft about 9 feet wide, with a mass of about 700 pounds entered the atmosphere of Titan, Saturn’s largest moon. Over the next two and a half hours, the Huygens probe, as the spacecraft was known, would report data from its descent through the thick atmosphere of Titan to the orbiting Cassini spacecraft above, and back to Earth. It also returned an image and data from the surface.
WASHINGTON (NASA PR) — NASA has announced that our next destination in the solar system is the unique, richly organic world Titan. Advancing our search for the building blocks of life, the Dragonfly mission will fly multiple sorties to sample and examine sites around Saturn’s icy moon.
LAUREL, Md. (JHUAPL PR) — It sounds like science fiction: fly a robotic rotorcraft over the dunes of an alien moon. But NASA is giving a team led by the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, the opportunity to turn this idea into space exploration reality.
PARIS (NASA PR) — Data from NASA’s Cassini spacecraft has revealed what appear to be giant dust storms in equatorial regions of Saturn’s moon Titan. The discovery, described in a paper published on Sept. 24 in Nature Geoscience, makes Titan the third Solar System body, in addition to Earth and Mars, where dust storms have been observed.
The observation is helping scientists to better understand the fascinating and dynamic environment of Saturn’s largest moon.
LOS ANGELES (NASA PR) — JPL has won an Emmy Award for Outstanding Original Interactive Program for its coverage of the Cassini mission’s Grand Finale at Saturn. The award was presented Saturday, Sept. 8, at the Creative Arts Emmy Awards in Los Angeles by the Academy of Television Arts & Sciences.
PASADENA, Calif. (NASA/JPL/Caltech PR) — These six infrared images of Saturn’s moon Titan represent some of the clearest, most seamless-looking global views of the icy moon’s surface produced so far. The views were created using 13 years of data acquired by the Visual and Infrared Mapping Spectrometer (VIMS) instrument on board NASA’s Cassini spacecraft. The images are the result of a focused effort to smoothly combine data from the multitude of different observations VIMS made under a wide variety of lighting and viewing conditions over the course of Cassini’s mission.
PASADENA, Calif. (NASA PR) — New research from NASA’s Cassini spacecraft’s up-close Grand Finale orbits shows a surprisingly powerful and dynamic interaction of plasma waves moving from Saturn to its rings and its moon Enceladus. The observations show for the first time that the waves travel on magnetic field lines connecting Saturn directly to Enceladus. The field lines are like an electrical circuit between the two bodies, with energy flowing back and forth.
PARIS (ESA PR) — Data from the international Cassini spacecraft have revealed complex organic molecules originating from Saturn’s icy moon Enceladus, strengthening the idea that this ocean-world hosts conditions suitable for life.
Very little was known about Enceladus prior to 2005 – the year when Cassini first flew close. Since then, it has become a continuous source of surprises, with secrets still being revealed even now, after the mission end.
I realize it’s a bit late, but here’s a look back at the major developments in space in 2017.
I know that I’m probably forgetting something, or several somethings or someones. Fortunately, I have eagle-eyed readers who really seem to enjoy telling me just how much I’ve screwed up. Some of them a little too much….
So, have at it! Do your worst, eagle-eyed readers!
PASADENA, Calif. (NASA PR) — A thrilling epoch in the exploration of our solar system came to a close today, as NASA’s Cassini spacecraft made a fateful plunge into the atmosphere of Saturn, ending its 13-year tour of the ringed planet.
“This is the final chapter of an amazing mission, but it’s also a new beginning,” said Thomas Zurbuchen, associate administrator for NASA’s Science Mission Directorate at NASA Headquarters in Washington. “Cassini’s discovery of ocean worlds at Titan and Enceladus changed everything, shaking our views to the core about surprising places to search for potential life beyond Earth.”
NASA’s Cassini spacecraft is on final approach to Saturn, following confirmation by mission navigators that it is on course to dive into the planet’s atmosphere on Friday, Sept. 15.
Live mission commentary and video from JPL Mission Control will air on NASA Television and the agency’s website from 7 to 8:30 a.m. EDT (4 a.m. to 5:30 a.m. PDT) on Sept. 15. A post-mission news briefing from JPL is currently scheduled for 9:30 a.m. EDT (6:30 a.m. PDT), also on NASA TV.
A new NASA e-book, The Saturn System Through the Eyes of Cassini, showcasing compelling images and key science discoveries from the mission, is available for free download in multiple formats at:
PASADENA, Calif. (NASA PR) — NASA’s Cassini spacecraft is on final approach to Saturn, following confirmation by mission navigators that it is on course to dive into the planet’s atmosphere on Friday, Sept. 15.
Cassini is ending its 13-year tour of the Saturn system with an intentional plunge into the planet to ensure Saturn’s moons – in particular Enceladus, with its subsurface ocean and signs of hydrothermal activity – remain pristine for future exploration. The spacecraft’s fateful dive is the final beat in the mission’s Grand Finale, 22 weekly dives, which began in late April, through the gap between Saturn and its rings. No spacecraft has ever ventured so close to the planet before.
PASADENA, Calif. (NASA PR) — Few missions can match the achievements of NASA’s groundbreaking Voyager 1 and 2 spacecraft during their 40 years of exploration. Here’s a short list of their major accomplishments to date. (more…)
