The
COMET-ORB
(expert
community
on
space
dynamics)
is
pleased
to
announce
that
a
seminar
on
small
bodies
(structure,
physical
parameters,
ephemerides,
and
more)
will
take
place
on
April
11th
2023.
This
one-day
seminar
will
give
the
opportunity
to
many
specialists
to
present
their
work
about
the
physical
aspects
of
small
bodies
(comets,
asteroids,
natural
satellites,
etc.),
and
also
on
some
space
mission
aspects
(instruments,
orbits,
etc…).
The
presentations
will
be

Mission analysis for future and in-flight interplanetary missions
ORB - Mécanique Orbitale
Europe
has
a
long
tradition
of
space
exploration.
It
ranges
from
the
vicinity
of
the
Earth
(Smart-1
around
the
Moon)
to
the
most
distant
landing
ever
performed
in
history
(Cassini/Huygens)
through
the
journey
to
a
comet
(Rosetta/Philae).
European
interplanetary
missions
cover
the
full
range
of
applications:
Sun,
planets,
satellites,
comets,
asteroids.
The
objective
of
this
seminar
is
to
perform
a
state-of-the-art
of
on-going
and
future
missions.

Improved management of maneuver uncertainties in LEO
ORB - Mécanique Orbitale
In
a
perfect
world,
covariances
would
not
exist.
In
a
slightly
less
perfect
but
still
wonderful
world,
they
would
be
tiny
ellipses.
But
in
our
world,
it's
pancakes,
or
bananas.
So
we
have
developed
new
recipes
to
be
able
to
cook
them
as
well
as
possible,
especially
when
we
add
the
mystery
ingredient:
manoeuvres.
Do
not
hesitate
to
join
us
for
this
tasty
seminar
which
will
combine
theory
and
practice,

On
October
15,
2020,
COMET-ORB
organized
a
seminar
on
the
latest
advances
in
atmospheric
modeling
for
space
mechanics
issues.
The
prediction
of
the
atmosphere
behavior
is
a
crucial
problem
for
the
calculation
of
satellite
trajectory,
so
COMET
ENV
and
OPS
have
joined
for
this
seminar
on
this
topic.
