That's interesting. I think I need to sign on to one of these "Exoplanet Explorers citizen scientist project" next time, I will need to first log into website where this sort of thing is done. I suppose it doesn't happen very often, though I might be wrong...

Sometimes its useful to have pointed out fairly simple obstacles to landing on a moon like Europa. I think one of the plans involved using a helicopter to hover over the surface...
That would be great, DW. Have you got a good telescope?Originally Posted by Dreamwoven

Nah, I don't have a telescope at all. And our old croft is in deep forest, so no good view of the stars. I guess its not a good idea for me to be involved in a citizen science project...
Take a look at that link. Maybe there is something for you there.

Those are useful links! Zoouniverse is one I will try. Will let you know how I got on.
I abandoned the attempt to use zooniverse, there is another linking system there, academia instead of LinkedIn that I use. Its the apps that tripped me up. I didn't realise apps cost something to use! And since I had closed my PayPal account I wouldn't be able to pay the bill, so I abandoned my attempt to join academia.
I think you were right. I suppose there are free ups to but what everyone wants mostly is money. One can´t be too careful these days. Some things are offered as free and then they guide you to the taxes or the donation.

Awesome !
Watching the Super/Blue/Blood Moon eclipse... nearly 50% now in Northern California where I live. Clear skies and warm outside... also on the NASA cable channel and on youtube live at https://www.youtube.com/watch?v=wwMDvPCGeE0
We should see totality in my location.

Lucky you! Haven't seen a clear sky in all off January. Here it snowed all day today, we had about 3 inches of snow. Snows just about every day here...Piles of it along the roadside.

TITAN HAS 'SEA LEVEL' LIKE THE EARTH
NASA
Saturn's moon Titan is nearly a thousand million miles away from the Earth,
but a recently published paper based on data from NASA's Cassini spacecraft
reveals a new way in which Titan and our own planet are similar. Just as the
surfaces of oceans on the Earth lie at an average elevation that we call
'sea level', Titan's seas also lie at an average elevation. That is the
latest finding that shows remarkable similarities between the Earth and
Titan, the only other object that we know of in our Solar System that has
stable liquid on its surface. The twist at Titan is that its lakes and seas
are filled with hydrocarbons rather than with liquid water, and water ice
overlain by a layer of solid organic material serves as the bedrock
surrounding the lakes and seas. The new paper finds that Titan's seas
follow a constant elevation relative to Titan's gravitational pull -- just
like the Earth's oceans. Smaller lakes on Titan, it turns out, appear at
elevations several hundred feet, or metres, higher than Titan's sea level.
Lakes at high elevation are commonly found on Earth. The highest lake
navigable by large ships, Lake Titicaca, has a water volume of nearly 900
cubic kilometres and a surface that is over 3,800 metres above sea level.
The new study of Titan suggests that elevation is important, because Titan's
liquid bodies appear to be connected under the surface in something akin to
a terrestrial aquifer system. Hydrocarbons appear to be flowing underneath
Titan's surface in the way that water flows through underground porous rock
or gravel on Earth, so nearby lakes communicate with each other and share a
common liquid level.
Interesting paper DW. I wonder if thiese hydrocarbons funtion as noutishment for any species.

A curious story:
NASA confirms amateur astronomer has discovered a lost satellite
"Some 12 years since it was thought lost because of a systems failure, NASA’s Imager for Magnetopause-to-Aurora Global Exploration (IMAGE) has been discovered, still broadcasting, by an amateur astronomer. The find, which he reported in a blog post this week, presents the possibility that NASA could revive the mission, which once provided unparalleled views of Earth’s magnetosphere.
The astronomer, Scott Tilley, spends his free time following the radio signals from spy satellites. On this occasion, he was searching in high-Earth orbit for evidence of Zuma, a classified U.S. satellite that’s believed to have failed after launch. But rather than discovering Zuma, Tilley picked up a signal from a satellite labeled “2000-017A,” which he knew corresponded to NASA’s IMAGE satellite. Launched in 2000 and then left for dead in December 2005, the $150 million mission was back broadcasting. It just needed someone to listen."

Yes, it is interesting how space projects that we assumed were dead and finished suddenly spring back to life.
