Ok at 6:30pm PDT NASA Tv will be covering the Orbit Insertion of Saturn.

At 6:11pm Cassini will turn its antenna towards Earth for the Insertion.

At 7:36pm PDT or therabouts, Cassini begins its burn to slow down to be captured into Saturns Orbit for 96 minutes.

At 9pm PDT Cassini should be in Orbit. Pictures of the Rings won't be due until July 1st about 6am.

Any news on how it went? I've been at work all evening.

All looks good from JPL's side. The burn started at 6:12pm PDT, for the insertion. We'll know by at least midnight PDT if everything went smoothly.

28 minutes ago JPL was excited that the first movement went well, and sometime soon we should know when Cassini is in orbit.

As of 11:14pm 6/30/04 Cassini successfuly entered Saturns gravity. For 95 minutes everything went well, and JPL's was estatic. Now for the ESA wait for Huygens Probe later this year. I'm sorry I can't give more info, but if you go to Nasa.gov/cassini they should have all the preleminary stuff for all you.

I'm giving a real short account of what happened.

July 1, 2004 first pictures have come in of Saturns Rings. Pretty detailed stuff, but nothing on press reports as of yet being this is 6:30am PDT here.

Pretty exciting and stuff.

Heres the picture.

September update

Keeping the torch lit for future readers...Cassini has found two new moons orbiting between Mimas and Enceladus.http://saturn.jpl.nasa.gov/cgi-bin/gs2.cgi?path=../multimedia/images/small-moons/images/PIA06105.jpg&type=image

What I find interesting is that Saturn has lightening storms around the rings at the equator. Some of the bolts extend far out into space which is unusual.


When Cassini entered the magnetic field of Saturn there were a series of pops but only sporatic intervolts, so I'm learning about Saturn as most are, so hopefully this will give a better understanding why this planet is much different in gravity than say Jupiter.


Both being Gas giants they would exhibit some similar behavior not all that much closer I think. Both are completely different just by atmosphere alone, besides Jupiter has the killer magneto sphere that could cause us humans some damage, if we were to travel close enough. I'd say huge sucking power, of course the Sun (Sol) is much more powerful of course.

Kind of quiet on the board lately.  Well I heard on the news that Cassini is making its closest approach to Titan today.  Does anyone know when the Huygens probe will be released?

Scratch the request, Huygens will be sent on Christmas Eve.

And Huygens will reach Titan a few weeks later, on January 14th, I think.

I think the idea is that it should land on Christmas day.

From what I remember from a documentary about the Huygens probe, it should fall through the atmosphere of Titan and rotate very slowly, taking pictures and using a spectrometer to find the main elements on the moon. It is expected that Titan would a very large water atmosphere, with huge glaciers.

The documentary, Horizon, also suggested that Titan has the ability to support life. It is thought that the liquid water could react with the atmosphere to make amino acids, unfortunately because Titan is so cold all water is ice. However, scientists have suggested that there could be water volcanoes on the surface of Titan, and that there is a lot of water under the surface of the moon. If this water could reach the surface via a volcano and react with the atmosphere, there is a chance that the creation of amino acids is possible.

I cannot remember what its atmosphere was. I thought it was hydrocarbons too, but I'm not sure, I'll try and find out.

ESA has a habit of doing big things on Christmas Day. Last year the Beagle 2 Mars probe was supposed to land on Christmas Day, but unfortunately we never knew what happened to it.

Anyway, it was a very informative program. ESA aren't exactly known for their wonderful explanations! :D

About 94% nitrogen and 6% methane.

Yes, a nitrogen and hydrocarbon atmosphere, they expected pools of liquid methane didn't they?

Huygens to plumb secrets of Saturn moon

By Michael Coren, CNN

(CNN) -- The Huygens probe will plunge through the orange clouds of Saturn's moon Titan Friday, offering scientists their first glimpse of the mysterious moon.

"It's going to be the most exotic place we've ever seen," said Candice Hansen, a scientist for the Cassini-Huygens mission. "We've never landed on the surface of an icy satellite. We know from our pictures that there are very different kinds of geological processes."

If all goes well, the saucer-shaped Huygens will enter the thick atmosphere of Titan Friday at about 5:13 a.m. (ET). The data should start trickling in about five hours later.
