Hubble has been good for
planetary science – and vice versa
• Hubble is capable of observing almost any moving target
in the Solar System, with a quick response to transient
events
• Best of both worlds: Hubble has a strong history of
supporting (and sometimes inspiring) planetary missions
• Hubble’s superb sensitivity and resolution are ideal for
studying small Solar System bodies or features
• Important planetary observations have happened at
critical points in the Hubble mission

Top Ten Hubble Telescope Excuses
10. The guy at Sears promised it would work fine.
9. Some kids on Earth must be fooling around with a garage door opener.
8. There's a little doohickey rubbing against the part that looks kind of like a cowboy hat.
7. See if you can think straight after 12 days of drinking Tang.
6. Bum with squeegee smeared lens at red light.
5. Blueprints drawn up by that "Hey Vern!” guy.
4. Those damn raccoons!
3. Shouldn't have used G.E. components.
2. Ran out of quarters.

1. Race of super-evolved galactic beings are screwing with us.
Solar System observations
helped fill the void until the first
HST Servicing Mission (SM1)
Despite bugs, breakdowns, and its
famous mirror flaw, Hubble still gives a
clear view of the cosmos - sometimes

They were later named Styx
and Kerberos – despite the
suggestion from Captain Kirk
and Spock

New Horizons could fly by
after Pluto

Will their
spaceship
come in?
Most Solar System objects
will be explored using only
Earth-based resources, until
those observations justify
new probes sent to explore
them in greater detail…

This graphic shows the location of water vapor detected over Europa's south pole that
provides the first strong evidence of water plumes erupting off Europa's surface.
Hubble didn't photograph plumes, but spectroscopically detected auroral emissions
from oxygen and hydrogen. The aurora is powered by Jupiter's magnetic field. The
image of Europa is derived from a global surface map generated from Voyager and
Galileo observations.

This is an artist's concept of a
plume of water vapor thought to
be ejected off of the frigid, icy
surface of the Jovian moon
Europa, located 500 million miles
from the Sun.
Hubble Space Telescope
spectroscopic measurements
lead scientists to calculate that
the plume rises to an altitude of
125 miles and then probably
rains frost back onto the moon's
surface. Previous findings
already point to a subsurface
ocean under Europa's icy crust.
