Space probe shows comet sense

Deep Space 1 reveals Borrelly's dark secrets.

TOM CLARKE
Nature Science Update
December 14, 2001

A state-of-the-art space probe has shed new light on what may be the darkest
object in the Solar System.

The potato-shaped comet Borrelly, although less showy than its better-known
cousin Halley, is turning out to be something of an enigma, researchers told
this week's meeting of the American Geophysical Union in San Francisco.

Bad behaviour

As if Borrelly's blackness wasn't enough, other DS-1 data suggest that it is
also behaving very strangely for a comet.

The Sun's heat boils off ice, other chemicals and dust trapped in comets. On
bodies such as Halley, these emissions occur evenly. But jets of material
spew out from patches in Borrelly's narrow middle section. "They look just
like nozzles," says Laurence Soderblom of the US Geological Survey in
Flagstaff, Arizona.

http://www.estec.esadot nl/conferences/hvis2003/index.html

                                  HVIS 2003

 Hosted by the European Space Agency's Research & Technology Centre (ESTEC)

                               7-10 April 2003
                          Grand Hotel Huis ter Duin
                         Noordwijk, The Netherlands

The Hypervelocity Impact Symposium is a regular event that is dedicated to
enabling and promoting an understanding of the basic physics of high
velocity impact and related technical areas. This international event
provides a forum for researchers to share and exchange a wealth of knowledge
through oral and poster presentations and technical exhibits.

HVIS 2003 will be the eighth symposium in a series. It will be hosted by
ESTEC and held in Noordwijk, The Netherlands. The dates of the conference
coincide with the tourist season in the bulb district and Noordwijk is
located in this district.

The technical sessions will be held at the Grand Hotel Huis ter Duin,
Noordwijk during April 7-10, 2003.

All papers presented at the Symposium will be published in a refereed volume
of the International Journal of Impact Engineering.

Symposium topics

   * Hypervelocity phenomenology studies
   * High-velocity launchers and diagnostics
   * Spacecraft meteoroid and debris shielding and failure analysis
   * Material behaviour under high velocity impacts
   * Fracture and fragmentation
   * High velocity penetration mechanics and target response
   * Analytical and numerical simulation techniques
   * Asteroid impact and planetary defence technology
   * Penetration mechanics of shaped charges and explosively formed
     penetrators
   * Planetary impacts

Call for papers

Abstract of proposed papers are solicited from those actively interested and
involved in hypervelocity impact. The preferred method of submitting
abstracts is using the form on this web site.

If it is not possible to submit your abstract through the web site, it may
be submitted by e-mail as an attachment or by mailing a printed copy, along
with a diskette copy to the following address:

HVIS 2003
ESTEC Conference Bureau
Postbus 299
NL-2200 AG Noordwijk
The Netherlands
Tel: +31-71-565-5005
Fax: +31-71-565-5658
E-mail: confburo@esa.int

Abstract must be received no later than May 15, 2002

Authors will be notified in June 2002 of the review decision for their
proposed paper. An author's packet will be mailed to authors whose abstracts
are accepted.

Acceptance of an abstract indicates preliminary acceptance of a paper for
publication in the International Journal of Impact Engineering, subject to a
technical peer review with final recommendation on the basis of such review.

Abstract Guidelines

   * Abstracts should be at least 500 words plus figures and references.

   * The official language is English.

   * Abstracts must be cleared for public release with unlimited
     distribution. An abstract booklet of accepted papers will be
     distributed at the symposium.

   * Include name, address, affiliation, phone number, fax number and e-mail
     address of the primary author.

   * Indicate author's preference for oral or poster presentation

   * Indicate appropriate topic.

Commercial Exhibits

Commercial Exhibits will be on display during the entire symposium giving
attendees ample opportunity to meet with company representatives. Companies
interested in exhibiting should contact the ESTEC Conference Bureau, P.O.Box
299, 2200 AG Noordwijk, NL. Tel.. +31 71 5655005, Fax: +31 71 5655658,
