That's a great link, thanks

The Mars Reconnaissance Orbiter has a massive data rate of 1Mb/sec in comparison!

Rosetta is chatting too at 104.86 kb/sec.

And Voyager 2 is still working away at 159b/sec. Voyager 1 was transmitting earlier today. NASA certainly got their money's worth with the Voyager probes!

That download progress bar must be so frustrating!

Especially when you see what they got yesterday, the scientists must be going mad waiting for the data to arrive.

Only 300 years until Voyager 1 arrives at the Oort Cloud

Despite all the marvels revealed by Cassini, Galileo, Mars Curiosity and New Horizons, etc., the Voyager 'Grand Tour' will always be, for me, one of mankind's very greatest scientific and technical achievements.

When I saw this headline I thought Buzz had gone a stage further than hitting the moon hoax nutters http://www.telegraph.co.uk/news/scie...theorists.html

Good old Buzz!

Talking of cool dudes I love the fact that Brian May has been so prominent at NASA recently.

Brian or Bubba Bieber - tough choice.

An interesting article from the National Geographic sums up the discovery.

What a terrible shame - two deaths at once.

He must be totally devastated.

bless him, he wrote a lovely post about them:
"I lost two very important women in my life yesterday. My sister Maddy & my first wife Joan - the mother of my three children. They both passed on opposite sides of the country within hours of each other. They were two classy respectable ladies who were both the family glue holding our clans together with love. I will miss them dearly. ‪#‎AldrinFamily‬"

The man has class - no doubt about that.

I wonder who's responsible for that ludicrous headline. Is the search for Earth-like exoplanets now so unremarkable now that they feel they have to 'sex up' the story by adding attention grabbing rubbish? Given that Kepler-452b is likely to be a 'super Earth' I'm surprised they didn't describe it as being 'on steroids'. *rolls eyes*

Interesting story though, despite the BBC journalism. Perhaps one day mankind might visit one of these worlds.

Buzz is a friend on facebook he posted that together with a photo 4 hours ago.

I doubt it - even in the far future.

The distances are simply far too vast - we are effectively alone in the universe no matter how many possible civilisations there could be in our own galaxy.

Even the Oort cloud is probably beyond us.

You're assuming that our technology could never improve so radically. Perhaps an understanding of dark matter and dark energy might provide some new approach to propulsion, or an artificial intelligence might solve the problems for us. If mankind is still around in another 1000 years its technology will be indistinguishable from magic. The hardest part will be not wiping ourselves out first.

But the speed of light is still the barrier - even if we approach it with probes in the far future the visible universe is just so impossibly massive

"They" could possibly visit us though, especially if they are far ahead of us in intelligence.

Okay, perhaps that particular planet is a very long way away, but there are closer ones. We'll definitely require near light speed propulsion, I'll grant you, which seems quite fanciful at the moment. As do space bending technologies. But until they were discovered or invented a lot of modern science and technology was unimaginable by most people.

Which do you think we'll solve first (if any); the hard problem of consciousness or mega propulsion technology?
