    The Principal Investigator for RISE is William Folkner of JPL, who led the 1997 investigation of Mars's core using the radio link between Earth and NASA's Mars Pathfinder. RISE uses the spacecraft's radio connection with Earth to assess perturbations of Mars's rotation axis to within 10 centimeters.

  3. Interplanetary Internet - Wikipedia

    en.wikipedia.org/wiki/Interplanetary_Internet

    Simplified Interplanetary Internet overview, Mars to Earth communication. The interplanetary Internet is a conceived computer network in space, consisting of a set of network nodes that can communicate with each other. [1] [2] These nodes are the planet's orbiters and landers, and the Earth ground stations.

    Direct teleoperation of a Mars rover is impractical, as the round trip communication time between Earth and Mars ranges from 8 to 42 minutes and the Deep Space Network system is only available a few times during each Martian day . [1] Therefore, a rover command team plans, then sends, a sol of operational commands to the rover at one time. [1]

    Fish-eye lens view of the interior of Cupola with shutters closed Berthing operations within Cupola. The International Space Station Cupola was first conceived in 1987 by Space Station Man-Systems Architectural Control Manager Gary Kitmacher as a workstation for operating the station's Canadarm2 robotic arm, maneuvering vehicles outside the station, and observing and supporting spacewalks.

  7. Mars cycler - Wikipedia

    en.wikipedia.org/wiki/Mars_cycler

    [6] [7] For each EarthMars cycler that is not a multiple of seven synodic periods, an outbound cycler intersects Mars on the way out from Earth while an inbound cycler intersects Mars on the way in to Earth. The only difference in these trajectories is the date in the synodic period in which the vehicle is launched from Earth.

  8. Cosmic distance ladder - Wikipedia

    en.wikipedia.org/wiki/Cosmic_distance_ladder

    The cosmic distance ladder (also known as the extragalactic distance scale) is the succession of methods by which astronomers determine the distances to celestial objects. A direct distance measurement of an astronomical object is possible only for those objects that are "close enough" (within about a thousand parsecs) to Earth. The techniques ...
