Since the arrival of the Mars Global horizon. All of these quests were limited to our planet Surveyor a decade ago, orbiting scientific spacecraft and or using observations of the heavens from Earth bound surface rovers have been providing us with information tools until half a century ago when advances in rocketry about the surface and atmosphere of our neighboring freed us to explore beyond our "Blue dot" and to look planet in order to better understand its evolution and back at our own world in a whole different way.

Missions planned in the next environment and a hellish temperature and pressure decade with sophisticated remote sensing instruments, at its surface? Is our planet heading in that direction balloons, probes, and possible surface stations will hopefully shed more light on its evolution path.

are turning upside down our models of how planetary systems look like, showing significant differences from the simple orderly model of our own solar system. Within the next decade, we will be able to get "family portraits" of the neighboring few thousands FIGURE 8.7 Comet Temple 1 before and after Deep Im- planetary systems and statistical assessment of how 8.07a&b combined.eps pact.

Their mass, orbit, size, temperature, atmospheric composition and some temporal variation can be determined without resolving the planet beyond one pixel. Getting resolvable planet images might be a herculean endeavor, but it is not any more far fetched than having rovers on FIGURE 8.9 K epler will observe transits of exoplanets.

Images from the Hubble Telescope, Spitzer, Chandra and other space telescopes are now embedded in our textbooks, used by artists and advertisers, and are com mon front cover news. Over the next decade, the advent of the James Webb Space Telescope ( JWST)

tor the ocean temperature and currents, wind patterns under the cloud cover of hurricanes, changes of the ice cover at both poles, the dynamics of the ozone layer that protects life on Earth, the changes in the vegeta tion cover, among many other environmental elements. Within the next decade we will be able to measure the ocean salinity from space, map in three dimensions the emissions, circulation and absorption of carbon dioxide, the subtle tectonic motion of plates leading to assessment of high risk areas, monitor the changes in biomass and the full inventory of atmospheric gases, detect subtle changes in the surface water (with alti metric changes)
