Titan Surface Probe: Cassini Flyby & Huygens Descent

In summary, the Cassini-Huygens mission successfully flew by Titan yesterday (10/27). The probe released a small probe, Huygens, with the intention of parachuting to the surface (possibly liquid) of the moon. Huygens' descent thru Titan's atmosphere is scheduled to occur in late December, around christmas. The article points out that this is the first attempt to land a probe on any moon besides Earth's.

here is an article posted yesterday (Friday)
http://www.rednova.com/news/display/?id=96361

what other articles do you have about this?

a flyby of Titan by the Cassini craft
releasing a small probe, Huygens,
intended to parachute to surface (possibly liquid)

Cassini will come within 1200 km of Titan
Huygens will be released during the flyby and will
take several weeks to approach the moon

Huygens descent thru Titan atmosphere is scheduled
to occur in late December, around christmas

the article points out that this is the first attempt to
land a probe on any moon besides earth's.
No probe has been landed on a Mars moon or on a Jovian moon.

have there been recent threads about Cassini, and in particular
about the Huygens probe? Anyone have links to other
current articles?

Here is a link to Nasa's Cassini-Huygens misision.

One or two months ago I had downloaded an interesting report from this web, but now I don't find it here. PF doesn't allow to attach this pdf archive because of its size.

And from ESA...

I found this quite helpful...

http://www.rssd.esa.int/SB-general/Projects/Huygens/Mission/Huygens.html

I believe Huygens' arrival at Titan will now be mid-January 2005 due to rescheduling of the mission. The reason for rescheduling is quite interesting in itself, I'll try to find links...

Cheers.

EDIT: this page gives a rough outline why it had to be rescheduled...

It is a relief to read that Cassini will store Huygens' data on a 'solid-state recorder.' I remember the problems the Galileo probe had with the tape recorder it used to store digital data.

Here's where I go to check on the status on the mission...

Successful flyby of Titan yesterday (closest ever)! :approve: Here's the CNN article...
http://www.cnn.com/2004/TECH/space/10/27/cassini.titan.ap/index.html

So far, they were unable to determine whether hydrocarbon oceans/lakes are present.

Looking forward to Huygens! :cool:

1. What is the purpose of the Titan Surface Probe mission?

The Titan Surface Probe mission, also known as the Cassini-Huygens mission, was designed to study Saturn and its largest moon, Titan. The main objective was to gather data and images of Titan's surface and atmosphere, providing insights into the moon's geology and potential for life.

2. How did the Cassini spacecraft reach Titan?

The Cassini spacecraft was launched in 1997 and began its journey to Saturn. It took seven years to reach the Saturn system, during which it made flybys of Venus, Earth, and Jupiter to gain gravitational assistance. Once in Saturn's orbit, Cassini used its engines to maneuver and position itself for flybys of Titan.

3. What is the Cassini flyby and Huygens descent process?

The Cassini flyby involved the spacecraft passing by Titan at a relatively close distance, capturing images and data with its various instruments. The Huygens probe, which was carried by Cassini, detached and descended through Titan's atmosphere, collecting data and images until it landed on the moon's surface.

4. What was discovered during the Titan Surface Probe mission?

The Cassini-Huygens mission revealed a wealth of information about Titan's surface and atmosphere. It discovered liquid methane lakes and seas, as well as evidence of a hydrological cycle on the moon. The data also showed that Titan has a thick, hazy atmosphere similar to early Earth, making it a potential location for extraterrestrial life.

5. How did the Titan Surface Probe mission end?

The Cassini spacecraft completed its mission in September 2017 by intentionally entering Saturn's atmosphere and burning up in a controlled manner. The Huygens probe, on the other hand, landed on Titan's surface and continued to send data for about 90 minutes before its batteries died. The mission provided valuable insights and data that will continue to be studied for years to come.
