Title: Cassini Equinox Mission
Post by: Recusant on April 24, 2009, 03:29:17 PM
The rings of Saturn, showing the 'spokes' fairly clearly.

You can go here (http://saturn.jpl.nasa.gov/index.cfm) to view a lot of pretty cool stuff sent back by Cassini.  It's still out there working!

The remnants of the Infra-space contrails caused by the sub light engines of a Briperion heavy interdictor whilst performing a crash stop maneuver close to Saturns rings in 1982. :)

Cassini's mission is nearing its end, having produced a treasure trove of beautiful images and intriguing science. One of the latest discoveries is hydrogen in the plumes being expelled from Enceladus (http://www.vox.com/science-and-health/2017/4/13/15288648/nasa-announcement-ocean-worlds-live-stream) (one of the moons of Saturn).

Quote[NASA] has found the most compelling evidence yet that the ocean underneath the icy crust of Enceladus, Saturn's sixth-largest moon, could contain life. In the past, the Cassini spacecraft has observed jets of water containing organic chemicals (http://www.vox.com/2015/5/7/8565683/enceladus-water-curtains) streaming from Enceladus. This latest finding adds a key ingredient for life to the mix: hydrogen. The presence of hydrogen in the jets makes NASA scientists suspect there are geothermal geysers on Enceladus's ocean floor. Like the geothermal vents deep within Earth's oceans, these could be home to microbes that use the chemical energy of hydrogen and carbon dioxide to produce methane and energy for life. (Also today, NASA announced it has collected more (not-yet-conclusive) evidence that there are also water vapor plumes emanating from Europa, Jupiter's icy moon. )

Talk about thread necromancy!!!
There's me wondering who this new member karadan is with so many posts!

Karadan is surely a Brit. He talks funny and uses Brit words such as "whilst".  Not only do mad dogs and Englishmen go out in the mid day sun, the Englishmen appear to be compelled to add extra letters to simple words such as ...while. They also insist that the word for describing the particular hue of an object is colour. Observe the completely un necessary and wasteful use of the letter U in the British word for color. 

Aside from that homely observation, let us all raise our glasses to Cassini. ( any excuse to raise our glasses will suffice. Scotch whiskey anyone?)

QuoteKaradan is surely a Brit.

Well, karadan claims to be located in the UK.  Could be an immigrant without British nationality, Icarus, and some forrigners are taught less than up to date English. Indian English used to be very formal - but the Internet is probably changing that.

Whilst we are on the subject . . . what's wrong with correct English? There are more archaisms in American (some of which sre being re-imported after about 400 years, like "skillet".)

;)

Anyway, some fabuloso pictures there!

Later: "karadan" is a Turkish word meaning "overland".

Eyes on Cassini

Cassini crosses the gap between the innermost ring and Saturn on April 26th, 2017.

That was yesterday.  :tellmemore:

Now you can ride onboard the spacecraft throughout the entire mission (20 years) using "Eyes on Cassini" on your Mac or PC.

In this interactive visualization, you can ride along with the Cassini spacecraft at any time during the entire mission, a period of 20 years! For example, watch the arrival at Saturn on July 1st, 2004, or see Cassini launch the Huygens probe and follow it to Titan, the largest moon of Saturn.

I downloaded it, and have done a bit of exploring. It looks like there is a lot of intriguing stuff there. Thank you, Magdalena!  :)

I downloaded it as well.  :)
But for some reason, my computer is slow right now, so I'm gonna have to wait to do some exploring.  :(
Thank you for starting this thread.  :beer:

Cool! Thanks, Mags!

Downloading now...

JPL has tours - I should really take one some day.

Fascinating stuff Recusant.   A link from the video takes us here for more fascinating stuff....https://www.youtube.com/watch?v=9L471ct7YDo

Farewell to Cassini: it's set to auger into Saturn. As I post this, there are about 10½ hours left (https://saturn.jpl.nasa.gov/mission/saturn-tour/where-is-cassini-now/).

There's a live feed from NASA (https://www.youtube.com/watch?v=wwMDvPCGeE0) as well.

The final image from Cassini. It went into the atmosphere of Saturn somewhere in the area shown.

Was going to say, "Cool images" but I guess it got very hot in the last seconds!
