Slide8Slide9Information on Mercury:
Mercury is the closest planet to the
Sun.
Mercury's surface temperature can reach a scorching 840 o
F
(450
o
C) during the day but can
plummet to minus
275
o
F (minus
170
o
C) at night.Mercury is the smallest planet — it is only slightly larger than Earth's
Moon
.
Since
it has no significant atmosphere to stop impacts, the planet is pockmarked with craters
.

Slide10Information on Mercury:
Mercury’s year is 88 days and its day is
59 Earth-days. For every two orbits of the Sun, Mercury completes three rotations about its axis.
Mercury’s oval-shaped orbit is highly
elliptical.
If
one could stand on Mercury when it is nearest to the
Sun
,
the Sun
would appear more than three times as large as it does when viewed from Earth
.

Slide12Slide13Slide14BepiColombo Mission
BepiColombo will explore Mercury. Europe's space scientists have identified the mission as one of the most challenging long-term planetary projects, because Mercury's proximity to the Sun makes it difficult for a spacecraft to reach the planet and to survive in the harsh environment found there.

Slide15Mission Objectives:
BepiColombo
has been designed to provide the measurements necessary to study and understand the composition, geophysics, atmosphere, magnetosphere and history of Mercury. In particular, the mission has the following scientific objectives:
Investigate the origin and evolution of a planet close to the parent star
Study Mercury as a planet: its form, interior structure, geology, composition and craters
Examine Mercury's vestigial atmosphere (exosphere): its composition and dynamics
Probe
Mercury's magnetized envelope (magnetosphere): its structure and dynamics
Determine the origin of Mercury's magnetic field
Investigate polar deposits: their composition and origin
Perform a test of Einstein's theory of general relativity

Slide16Mission Name:
BepiColombo is named after Professor Giuseppe Colombo from the University of Padua, Italy, a mathematician and engineer of astonishing imagination. He was the first to see that an unsuspected resonance is responsible for Mercury's habit of rotating on its axis three times for every two revolutions it makes around the Sun.
He also suggested to NASA how to use a gravity-assist swing-by of Venus to place the Mariner 10 spacecraft in a solar orbit that would allow it to fly by Mercury three times in 1974-5.

Bepi
) Colombo, grandfather of the flyby
(1920 – 1994)

Slide18Spacecraft:
The BepiColombo mission is based on two spacecraft:The ESA-led Mercury Planetary Orbiter (
MPO) with an instrument suite of 11 experiments and instruments. It traces a lower-apocentre orbit and is designed to study the planet itself.The JAXA-led Mercury Magnetospheric Orbiter (
MMO) carrying a payload of five experiments and instruments. It follows a higher-apocentre orbit and investigates the planet's magnetic
field.
Upon arrival, they will separate and enter their own orbits around Mercury.
The Mercury Transfer Module (
MTM
) will carry the interplanetary propulsion system, with the two solar array wings. It will be jettisoned on arrival.

Slide20Information on Mercury:
Mercury is the closest planet to the
Sun. As such, it circles the Sun faster than all the other planets.
Because the planet is so close to the Sun
, Mercury's surface temperature can reach a scorching
840
o
F
(450
o
C).
However, since this world doesn't have a real atmosphere to entrap any heat, at night temperatures can plummet to minus
275
o
F (minus 170 o C), a temperature swing of more than 1,100 o F (600
o
C), the greatest in the solar
system.
Mercury
is the smallest planet — it is only slightly larger than Earth's
Moon
. Since it has no significant atmosphere to stop impacts, the planet is pockmarked with craters
.

Slide21Information on Mercury:
Mercury
is the second densest planet after Earth, with a huge metallic core about 75 percent of the planet's diameter.
Mercury’s year is 88 days and its day is 59
Earth-days. For
every two orbits of the Sun, Mercury completes three rotations about its
axis.
Mercury’s
oval-shaped orbit is highly elliptical, taking Mercury as close as 29 million miles (47 million km) and as far as 43 million miles (70 million km) from the
Sun
. If one could stand on Mercury when it is nearest to the
Sun
,
the Sun
would appear more than three times as large as it does when viewed from Earth
.
No atmosphere: Mercury possesses an exosphere containing 42 percent oxygen, 29 percent sodium, 22 percent hydrogen, 6 percent helium, 0.5 percent potassium, with possible trace amounts of argon, carbon dioxide, water, nitrogen, xenon, krypton and neon.
