Here is a press statement from Alcatel:

"The Huygens space probe has arrived on Titan. The probe was built by prime contractor Alcatel Space, a subsidiary of Alcatel, leading a consortium of 40 companies and laboratories. Alcatel Space is the first European company to have met the challenge of constructing a spacecraft designed to resist such draconian conditions. This is the first time that a man-made object has landed on the moon of a planet so far away in our solar system. This is also the first time that an European probe has successfully landed on another part of the solar system.

"The interplanetary voyage of Cassini/Huygens took seven years, and made use of successive gravity boosts from Venus (twice), the Earth and Jupiter. Huygens had to stand up to temperatures of 212 deg F near Venus, and made a blind crossing of the asteroid belt between Mars and Jupiter, then the rings of Saturn. However, the technical challenge reached its zenith during the descent towards Titan, which lasted nearly three weeks after the separation from the Cassini mother-craft on December 25. Following aerodynamic braking in the upper atmosphere, then deployment of three parachutes to control the descent, the probe landed on the surface of Titan. Huygens is a veritable flying lab, featuring six advanced instruments to carry out all measurements expected by the scientific community.

"Meanwhile, Cassini is in orbit around Saturn for its own observation mission, while relaying data from Huygens back to Earth.

"The Cassini/Huygens programs was an unprecedented technical challenge, tackling aspects that had never before been studied:

- Major restrictions on mass and energy, given the distance to be traveled and the complex trajectory needed to reach Saturn via gravity boosts form Venus, Earth and Jupiter.

- Completely autonomous operation.

- High-precision Cassini/Huygens separation maneuvers.
Thermal shield adapted to an entry into Titan's atmosphere.

- Parachute deployment at supersonic speed.

- Sufficient robustness to stand up to unknown elements, especially atmospheric (furthermore, scientists have continuously changed their models since the knowledge of Titan was increased, which required an important effort to ensure successful entry).

"We are especially proud of this huge success by our customer ESA, in partnership with NASA and ASI," said Pascale Sourisse, Chairman and CEO of Alcatel Space. "Not only is it a world first in exploration of the universe, it also marks a major step forward in better understanding the origins of life. With the Huygens mission now accomplished, we want to reaffirm our unyielding commitment to carrying out the most demanding programs for interplanetary exploration and observation of the universe, alongside European scientists and space agencies. We hope that this mission will pave the way to other adventures that prove to be just as exciting, both scientifically and technologically."

1655 GMT (11:55 a.m. EST)

ESA says data is being received normally on the Channel B telemetry steam. However, the Channel A has a question mark surrounding it.

1658 GMT (11:58 a.m. EST)

The probe went through the entry phase, the parachute deployment was within 15 seconds of the planned time and onboard accelerometer data worked normally, officials are saying at the news conference. The playback of data continues.

1701 GMT (12:01 p.m. EST)

The temperature inside the probe was 25 degrees C as it was descending through 50 km altitude, the ongoing data review shows.

GioFX · 14-01-2005, 18:10

1706 GMT (12:06 p.m. EST)

Engineers says the Channel A and Channel B data paths from Huygens are redundant with the exception that Channel A is needed for the Doppler wind experiment with the Cassini orbiter. The Channel A telemetry stream isn't working as expected, but Channel B appears normal, ESA says.

.....ma sopratutto, sta sonda ha mandato qualche immagine?

GioFX · 14-01-2005, 18:27

ma li leggete mai i post?

e scusate, pensate poi che sia istantaneo ricostruire immagini partendo da un flusso di dati a bassissimo transfer rate?

1722 GMT (12:22 p.m. EST)

NASA's Cassini Saturn orbiter began downlinking science data from the European Space Agency's Huygens probe at 11:19 a.m. EST (1619 GMT), confirming the spacecraft not only survived its high-speed plunge into the atmosphere of Saturn's moon, Titan, but that its instruments worked to remotely explore one of the strangest worlds in the solar system.

parli della pappardella anglosassone che posti a tonnellate ogni volta che c'è un avvenimento di questo tipo!?

ps: il mio eng non che sia il massimo....mea culpa

The first picture from the descending Huygens probe showing the Titan surface has been revealed in mission control!

1956 GMT (2:56 p.m. EST)

The first image shows what appear to be drainage channels flowing to a possible shoreline, the camera's scientist says. The pictures are raw and unprocessed.

This is the first picture from Huygens released by ESA. It was taken at an altitude of 16 km as Huygens made its descent. Credit: ESA/NASA TV

... mah li non ha ancora attitanato ehm atterrato

cionci · 15-01-2005, 00:14

Ma non doveva essere liquida la superficie ? Sembra marte

bob_marley_23 · 15-01-2005, 11:28

ma è vero che la sonda atterrata nn è sopravvissuta + di 3 min?

cioè dovremo accontentarci di qualke fotarella e basta?....

25 ° celsius?
