Re: Asteroids: treasures of the past and a threat to the future (Forwarded)

Britain was hit by lumps of ice on the 6 February 2006 at 12 noon. I was
out in the street in London when suddenly there were loud explosions all
round with flashes in the sky. One exploded directly above me. I looked up
to see an orange fireball (I thought thats the sun, dont look) then I moved
under a streetlamp and the light brightened up the street. A man across the
street I had spoken to about the explosions fell over and just faded away
leaving a pile of clothes. A young attractive woman wearing red walking
towards me must have stripped because of the heat and ran nude in front of
me, fell over and just faded away. I think she was screaming but I could
not hear anything because of the roar or the explosion. A dog walking in the
middle of the road just faded out.

One of the explosions hit me in the chest and knocked me down.

They went on 15 minutes, every 30 seconds and then stopped.

A few days later I was in my front room and a huge heavy explosion occured
that shook the ground and there was a flash in the sky, to the north and
then some particulate rain came down, like white flecks.

On thursday I went to East Grinstead feeling ill and I had a sun tanned
face. I went to hospital (oh they said did you cause that explosion at East
Grinstead?) but they sent me to an emergancy place 16 miles away by taxi
(£20) and there I collapsed. I had dioreha and felt ill. They said the
radiation burn was not to bad and I had some heart procedure done by a
famous heart surgeon who was visting that day. He said something about a
bullet in my heart. A heart valve and three stents or something. I was given
vitamins and after 6 hours I took a train from Tonbridge Wells to London,
and on the way some more explosions shook the train with huge flashes in the
sky.

I vaguely remember that a few days before I had found a hydrogen bomb in the
dining room of a house near me and I put the safety pin back in that the
bomber had left on the table, there were five more round London, and others
over the country the delivery men had left a list of their deliver addresses
on the table before they left. I think they were all 20 Megaton.

I heard stories of the British army collecting lorryloads of these bombs and
taking them for disposal.

I have heard that the Bullring in Birmingham had taken a ground burst and
that trains don't go to Birmingham any more and that roads to Birmingham are
blocked with piles of earth and rock and the huge crater there is a tourist
attraction.

I understand too that Coventry and Manchester are similar.

None of this makes any sense and basicly I don't believe any of it, it is
just plain silly my mind is playing tricks on me.

The fall on the 6 of Feb was predicted by a poster, the same poster
predicted a for more serious fall on the 8 August, this is an update on
previous calculations of the 15 August and the 16th August. All in 2006.

The august fall is predicted as a long chain the lumps of ice like a string
of beads a million miles long and will bombard the earth in a wide swathe
around the equator for about a fortnight.

I still dont believe any of it and the posters are believed to be getting
messages from flying saucers, like Maia, but in view of the accurate
pediction of the 6 Feb 12 gmt I am getting quite frightened.

I am not the predictor, I am just another person who is bit worried.

If you survive then you are a survivor otherwise you are not. Thats it.

I would have thought a radar station like fylingdales could pick up this
object and make an accurate prediction so evacuations could take place.

Sorry, I cannot vouch for what I said but I think its true.

Asteroids: treasures of the past and a threat to the future

If a large asteroid such as the recently identified 2004 VD17 -- about 500
m in diameter with a mass of nearly 1000 million tonnes -- collides with
the Earth it could spell disaster for much of our planet. As part of ESA's
Near-Earth Object deflecting mission Don Quijote, three teams of European
industries are now carrying out studies on how to prevent this.

ESA has been addressing the problem of how to prevent large Near-Earth
Objects (NEOs) from colliding with the Earth for some time. In 1996 the
Council of Europe called for the Agency to take action as part of a
"long-term global strategy for remedies against possible impacts".
Recommendations from other international organisations, including the UN
and the Organisation for Economic Cooperation and Development (OECD), soon
followed.

In response to these and other calls, ESA commissioned a number of threat
evaluation and mission studies through its General Studies Programme
(GSP). In July 2004 the preliminary phase was completed when a panel of
experts appointed by ESA recommended giving the Don Quijote
asteroid-deflecting mission concept maximum priority for implementation.

Now it is time for industry to put forward their best design solutions for
the mission. Following an invitation to tender and the subsequent
evaluation process, three industrial teams have been awarded a contract to
carry out the mission phase-A studies:

* a team with Alcatel Alenia Space as prime contractor includes
subcontractors and consultants from across Europe and Canada; Alcatel
Alenia Space developed the Huygens Titan probe and is currently working on
the ExoMars mission

* a consortium led by EADS Astrium, which includes Deimos Space from Spain
and consultants from several European countries, brings their experience
of working on the design of many successful ESA interplanetary missions
such as Rosetta, Mars and Venus Express

* a team led by QinetiQ (UK), which includes companies and partners in
Sweden and Belgium, draws on their expertise in mini and micro satellites
including ESA's SMART-1 and Proba projects

This month the three teams began work and a critical milestone will take
place in October when the studies will be reviewed by ESA with the support
of an international panel of experts. The results of this phase will be
available next year.

No reason for panic -- yet

The risk is still small however, and may decrease even further when new
observations are carried out. Still, if this or any other similar-sized
object, such as 99942 Apophis, an asteroid that will come close enough to
the Earth in 2029 to be visible to the naked eye, collided with our planet
the energy released could be equivalent to a significant fraction of the
world's nuclear arsenal, resulting in devastation across national borders.

Luckily, impacts with very large asteroids are uncommon, although impacts
with smaller asteroids are less unlikely and remote in time. In 1908 an
asteroid that exploded over Siberia devastated an unpopulated forest area
of more than 2000 km2; had it arrived just a few hours later, Saint
Petersburg or London could have been hit instead.

Fossils of the Solar System

Asteroids are a part of our planet's history. As anyone visiting the
Barringer Meteor Crater in Arizona, USA or aiming a small telescope at the
Moon can tell, there is plenty of evidence that the Earth and its cosmic
neighbourhood passed through a period of heavy asteroid bombardment. On
the Earth alone the remains of more than 160 impacts have been identified,
some as notorious as the Chicxulub crater located in Mexico's Yucatan
peninsula, believed to be a trace of the asteroid that caused the
extinction of the dinosaurs 65 million years ago.

Collisions have shaped the history of our Solar System. Because asteroids
and comets are remnants of the turbulent period in which the planets were
formed, they are in fact similar to 'time capsules' and carry a pristine
record of those early days. By studying these objects it is possible to
learn more about the evolution of our Solar System as well as 'hints'
about the origins of life on Earth.

Comet 67P/Churyumov-Gerasimenko is one of these primitive building blocks
and will be visited by ESA's Rosetta spacecraft in 2014, as a part of a
very ambitious mission -- the first ever to land on a comet. Rosetta will
also visit two main belt asteroids (Steins and Lutetia) on its way to
comet 67P/Churyumov-Gerasimenko. The mission will help us to understand if
life on Earth began with the help of materials such as water and organisms
brought to our planet by 'comet seeding'.

ESA's Science programme is already looking at future challenges, and its
Cosmic Vision 2015-2025 plan has identified an asteroid surface sample
return as one of the key developments needed to further our understanding
of the history and composition of our Solar System.

Work still in progress

Asteroids and comets are fascinating objects that can give or take life on
a planetary scale. Experts around the world are putting all their energy
and enthusiasm into deciphering the mysteries they carry within them.

With an early launch provisionally scheduled for 2011, Don Quijote will
serve as a 'technological scout' not only to mitigate the chance of the
Earth being hit by a large NEO but also for the ambitious journeys to
explore our solar system that ESA will continue to embark upon. The
studies now being carried out by European industry will bring the Don
Quijote test mission one step nearer.

Note for editors

Don Quijote is a NEO deflection test mission based entirely on
conventional spacecraft technologies. It would comprise two spacecraft --
one of them (Hidalgo) impacting an asteroid at a very high relative speed
while a second one (Sancho) would arrive earlier at the same asteroid and
remain in its vicinity before and after the impact to measure the
variation on the asteroid's orbital parameters, as well as to study the
object. Secondary mission goals have also been defined, which would
involve the deployment of an autonomous surface package and several other
experiments and measurements.
