  • Planet Compare - NASA Solar System Exploration
    NASA’s real-time science encyclopedia of deep space exploration Our scientists and far-ranging robots explore the wild frontiers of our solar system
  • Overview - VERITAS Tabs – NASA Solar System Exploration
    VERITAS will unlock the secrets of Venus’ surface and interior evolution by searching for evidence of past and present water, providing an inventory of current and recent volcanic and surface activity, and answering critical questions about the evolution of rocky planets

  • In Depth | Europa – NASA Solar System Exploration
    Surface Europa’s water-ice surface is crisscrossed by dark, reddish-brown cracks Based on the small number of observable craters, the surface of this moon appears to be no more than 40 to 90 million years old, which is youthful in geologic terms (the surface of Callisto, another of Jupiter’s moons, is estimated to be a few billion years old)
  • In Depth | Moons – NASA Solar System Exploration
    Of the terrestrial (rocky) planets of the inner solar system, neither Mercury nor Venus have any moons at all, Earth has one and Mars has its two small moons In the outer solar system, the gas giants Jupiter and Saturn and the ice giants Uranus and Neptune have dozens of moons
  • Energy Storage Technologies for Future Planetary Science Missions
    The Venus exploration mission concepts being considered for the next decade include: a) orbital missions, b) variable-altitude aerial platforms, and c) long-duration surface probes and landers Energy storage system needs for Venus missions once again depend on the type of mission (orbital surface aerial)
  • RPS 3D Viewer - NASA Solar System Exploration

  • In Depth | Sun – NASA Solar System Exploration
    Here, large bubbles of hot plasma (a soup of ionized atoms) move upward toward the photosphere, which is the layer we think of as the Sun's surface Surface The Sun doesn’t have a solid surface like Earth and the other rocky planets and moons The part of the Sun commonly called its surface is the photosphere
  • In Depth | Io – NASA Solar System Exploration
    Jupiter's rocky moon Io is the most volcanically active world in the solar system, with hundreds of volcanoes, some erupting lava fountains dozens of miles (or kilometers) high Io’s remarkable activity is the result of a tug-of-war between Jupiter's powerful gravity and smaller but precisely timed pulls from two neighboring moons that orbit farther from Jupiter – Europa and Ganymede Size
  • In Depth | 1P Halley – NASA Solar System Exploration
    The light of Halley was spread over an extended area, however, so its surface brightness was less than that of Venus During its 1986 appearance, Halley's nearest approach to Earth occurred on the outbound leg of the trip at a distance of 0 42 AU (39 million miles or 63 million kilometers)
