Philae comet could be home to alien life, say top scientists

Astronomers say features of comet landed on by spacecraft in November, such as black crust and icy lakes, suggest living micro-organisms beneath surface.

​

The comet landed on by the spacecraft Philae could well be home to an abundance of alien microbial life, according to leading astronomers.

Features of the comet, named 67P/Churyumov-Gerasimenko, such as its organic-rich black crust, are most likely explained by the presence of living organisms beneath an icy surface, the scientists have said.

Rosetta, the European spacecraft orbiting the comet, is also said to have picked up strange clusters of organic material that resemble viral particles.

New Horizons Closest Approach to Pluto: 7:49:57 a.m. EDT, (11:49:57 UTC) July 14, 2015 Tuesday.
​

Because of a 9-hour lag in round-trip communications between Earth and probe the folks at JHUAPL won't know how successful they are until almost 5pm EDT Tuesday afternoon.

I don't know how your cable runs in Florida Loki, but here in PA the Science channel has been advertising the last few weeks for a special one hour show; "Direct from Pluto: The First Encounter" on Wednesday the 15th, at 10pm EDT.

As NASA's unmanned New Horizons spacecraft speeds closer to a historic July 14 Pluto flyby, it's continuing to multi-task, producing images of an icy world that's growing more fascinating and complex every day.

On July 11, 2015, New Horizons captured this image, which suggests some new features that are of keen interest to the Geology, Geophysics and Imaging (GGI) team now assembled at the Johns Hopkins University Applied Physics Lab in Laurel, Maryland. For the first time on Pluto, this view reveals linear features that may be cliffs, as well as a circular feature that could be an impact crater. Just starting to rotate into view on the left side of the image is the bright heart-shaped feature that will be seen in more detail during New Horizons' closest approach.

The New Horizons spacecraft is now approaching a milestone – only one million miles to Pluto – which will occur at 11:23 p.m. EDT tonight, Sunday, July 12. It's approaching Pluto after a more than nine-year, three-billion mile journey. At 7:49 AM EDT on Tuesday, July 14 the unmanned spacecraft will zip past Pluto at 30,800 miles per hour (49,600 kilometers per hour), with a suite of seven science instruments busily gathering data. The mission will complete the initial reconnaissance of the solar system with the first-ever look at the icy dwarf planet.

Follow the path of the spacecraft in coming days in real time with a visualization of the actual trajectory data, using NASA's online Eyes on Pluto.

Hi Anak,

I don't have anything but over the air free TV... So I go to the NASA sites for what's new...

Looks like the most interesting side of Pluto will not be the side they see on the close fly by...

We will not be back to Pluto, so hope they have no problems.

Loki

PS Thanks for the NASA TV link, I was planning on checking if they would have it...

Wished it wasn't just a fly by it would have been real good to have an orbiter for a while.

Mind you one has to wonder at the maths involved in getting that sort of thing happening eh

Uh Oh!

Unfortunately there are consequences for trying a Plutonian insertion:
1. You need a significantly larger craft carrying a powerful rocket and fuel to burn,
2. To slow the craft enough to be captured by Pluto (which has only 7% Earth's gravity), you need to spend 2 years slowing the craft down (assuming cruise speed of about 60,000kph)

In practical terms, that means the mission costs significantly more, and will take much longer than the 9.5 yrs. The really tricky thing about going into orbit around Plutor is the effect of Charon, Nix, Styx, Hydra and Kerberos on the craft. The mass of these, and their orbital paths, were not known well enough to predict the calculations required for the orbital insertion, and the gravitational influence on the craft.

Thanks Colin I had no idea the gravitational pull of Pluto was so little and given that I see what you mean by the time and fuel status and also the implications of those other bodies. In my ignorance though I knew Pluto is small had not even taken into account for the specs you have given me (and I am guessing a few others).
I still think it is a shame that it was declassified as a planet purely on technicalities https://en.wikipedia.org/wiki/Definition_of_planet as I think those large planets ie Jupiter being mainly gas are hardly what conjures up in this tiny mind of mine being known as a planet.
