Prof Colin Pillinger announced in a press conference this morning that
the Beagle  2 team are hoping to receive offers of assistance from any
radio telescope capable  of receiving from Mars on a frequency of
401.56Mhz.

I ownder if the lack of any signal could be due to the landing site:
Take a look at this image from THEMIS which shows part of the target area.

I wonder which craft has the stongest cameras?
What will Mars Express see? Will it see Mars Polar Lander which was
lost years ago? Is it plan to find it?
Will it see Beagle 2 on the ground?

I predict with absolute confidence that next Thursday will set a new highest
temperature for the year.

When the Sun grows old, and becomes a red giant star, don't you think that
we will behold this beautiful sight from Earth?
I mean, surely the Sun is losing mass, and because of this the Earth will

Sir Isaac Newton, one of the founders of planetary science, was born on
December 25, 1642. So today is his birthday. That's as good an excuse
as any to celebrate!
Happy Newton's Birthday, everyone.

I just read this on BBC Online:

" Then there are the airbags. If anything goes wrong the engineers suspect
it will be them. They failed their first tests and had to be designed and

I have a few questions about the greenhouse effect
1.  What is the percentage of the atmosphere is water vapor?
2.  How potent a greenhouse gas is water vapor?
3.  How potent a greenhouse gas is CO2 and what percentage

I think I originally posted this question to the wrong group
forum...so I'll try again. Please....Im not a scientist (Im a
historian...but that is neither here nor there)...so please use
laymans terms if possible.

I have read that Earth underwent complete freezing of its oceans several
hundred million years ago - the sea ice at the equator was a mile thick, and
equatorial daytime temperatures were below -50 C.  This was due to the fact
that if ice forms below 35th latitude, enough sunlight is ...

Are there any good web sources to follow the Beagles progress?  I'm aware of
the Beagle home page, just wondering if there is any kind of real time feed
available.  I want to know if it succeeds or not as it's happening....

Is there any software in existence that I can use to show me the orbital
tracks/positions of the planets on any given date, preferably with some sort
of function to calculate when is best to perform an inter-orbit manoeuvre?
I'm in the planning stage of writing a sci-fi novel ...

Ken Tucker (who often posts here) has asked me to post the following
little BASIC program that he wrote with his son, Travis, some 15 years
ago. It was written in some old dialect of BASIC, with line numbers,
but works okay in QBasic, and probably others. What it does is to draw
