Hubble’s planetary mission

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

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.
