    Earthrise 2.0

    April 19th, 2012
    (updated May 3rd, 2023)

    On December 24, 1968, three Apollo astronauts circled the moon, becoming the first humans ever to do so. On their fourth orbit, Apollo 8 Commander Frank Borman interrupted the studies of the moon's cratered terrain to roll the spacecraft, bringing the three main windows around to face the direction of travel. All of a sudden, a bright sliver of light appeared from behind the lunar horizon. Within seconds, a sphere with dazzling white swirls and vivid shades of blue came into view. The astronauts quickly positioned the onboard cameras, first capturing a black-and-white image of Earth rising, and then snapping a color photo of the Blue Planet floating above the horizon. This breathtaking color image would later become known as the iconic Earthrise photograph. The visualization uses data collected by NASA's Terra satellite and Lunar Reconnaissance Orbiter to re-create this historic moment in space exploration. ||

    Earthrise

    April 19th, 2012
    (updated Nov. 14th, 2023)

    The famous color photograph known as Earthrise, as well as a black-and-white image taken a minute earlier, document the moment when Earth was seen for the first time by human eyes from behind the Moon. They were taken on December 24, 1968 by the crew of Apollo 8, the first humans to leave low Earth orbit.The sight of a small, intensely blue Earth rising above the barren, gray horizon of the Moon was one of the few things that NASA and the crew of Apollo 8 had not thoroughly planned and rehearsed beforehand. As historian Robert Poole noted, this lack of preparation meant that the sight of Earth came with the force of a revelation, not just for the astronauts but for everyone on the ground. We came all this way to explore the Moon, Apollo 8 astronaut Bill Anders said, and the most important thing is that we discovered the Earth.Using the latest elevation data from Lunar Reconnaissance Orbiter, this visualization attempts to recreate what the astronauts saw. The virtual camera of the rendering software is put in the position of the Apollo 8 spacecraft at the time of the photographs, as the spacecraft emerged from its fourth pass behind the Moon. It shows a two-minute interval centered on 16:39:06 UT (10:39 a.m. Houston time) on December 24, 1968. This is around the time of AOS (acquisition of signal), the moment when radio contact is re-established after being lost on the far side of the Moon.The position and motion of the spacecraft are based on a state vector, a set of (x, y, z) position and (vx, vy, vz) velocity values, published in NASA's Apollo 8 Mission Report about a year after the flight. The animator translated these values, given in Moon-centered inertial coordinates for Besselian year 1969.0, into a modern coordinate system, then calculated an orbit. The spacecraft was 110 km (68 miles, 60 nautical miles) above the surface of the Moon at 11.2°S 113.8°E when the Earthrise photograph was taken. ||
