1.
Explain why there is no surface on Jupiter or Saturn.
As a gas giant, Jupiter doesn't have a true surface
2.
Compare and contrast Jupiter and Earth - size, mass, the atmosphere and the core size?
Jupiter is almost 11 times the size of Earth, and just under 318 times as
massive
3.
Jupiter is composed primarily of
hydrogen and helium
4.
Describe Jupiter’s magnetic field, its origin and the evidence for its existence.
generated by electrical currents in the planet's outer core, which is composed
of liquid metallic hydrogen.
5.
Saturn’s largest satellite is
Titan
6.
Inside the
Roche
limit, tidal forces from a planet will overcome the internal
gravity of a moon and pull it apart.
7.
What are the four Galilean satellites?
List in order, starting closest to Jupiter.
Io, Europa, Ganymede and Callisto
8.
Why is Titan of interest to astrobiologists?
its chemistry and liquid cycle remind us of what the early Earth could have
looked like before life arose
9.
Explain why we don’t see evidence of heavy cratering on Europa?
its surface is tectonically too active and therefore young
10. Enceladus
is the most reflective object in the Solar System.

11.
Saturn’s moon
Titan
has a thick atmosphere composed primarily of
Nitrogen
.
This moon was recently explored by the
ESA's Huygens
probe, part of the
Cassini orbiter
spacecraft.
12.
What could explain the moon Iapetus’s discolored appearance?
influx of dark material from an external source
13.
The large circular or oval spots seen in Jupiter’s clouds are circulating
Storms
that have
remained stable for centuries.
14.
Provide
a comparative analysis of Jupiter and Saturn. What are three similarities?
What are three differences?
both possess rings, both have traditional and irregular moons in their orbit,
and both planets are made of primary liquid hydrogen. Jupiter has a great big
red spot and brighter colored bands.
15.
Go to the current events and read the article “Why is our trip to Jupiter taking so
long?” Write 10 – 15 sentence summary about it.
The European Space Agency (ESA) has revealed that the spacecraft Juice,
launched five months post-launch, has covered 370 million kilometers, only
5% of its journey to Jupiter. The spacecraft's orbital energy is inherited from
Earth's 30 km/s orbit around the Sun. A straight line to Jupiter would require
immense fuel and a larger fuel reserve to decelerate and orbit it upon arrival.
Earth and Jupiter's orbits are constantly changing, with distances varying
between 968 million kilometers and 600 million kilometers. To maintain an
extended presence around Jupiter, the approach must be slower, and the

spacecraft's mass plays a pivotal role. Juice, weighing over 6,000 kg, is one of
the heaviest interplanetary probes to date, and its gravity-assist or flyby
maneuvers will position it for its grand rendezvous with the Jovian system in
July 2031. The journey will include 35 flybys of Jupiter's moons and end with
Juice entering the orbit of Ganymede, marking a historic first for humankind.
However, every maneuver must be precise, as slight miscalculations could lead
to probe loss or require extensive fuel. The mission's overarching goal is to
study the potentially life-harboring oceans beneath the icy surfaces of Europa,
Ganymede, and Callisto, providing insights into the formation of planets and
moons across the universe.
