NASA's ESCAPADE Mission Captures Earth and Moon Portraits

• NASA's ESCAPADE spacecraft successfully imaged Earth and the Moon on July 3, 2026, capturing both visible and thermal infrared data.
• The images serve as a vital calibration test for the spacecraft’s onboard cameras before its arrival at Mars in September 2027.
• The spacecraft are currently in a "loiter" orbit near Lagrange point 2, awaiting a gravity-assist flyby of Earth in November 2026.

Imaging Findings

• Visible Light: With only 8% of the faces illuminated by the Sun, both Earth and the Moon appear as thin crescents.
• Thermal Infrared: Earth’s shadowed hemisphere glows due to heat from its atmosphere and surface (minus 10 to minus 44 degrees Fahrenheit).
• Thermal Contrast: Lacking an atmosphere, the Moon’s far side appears significantly colder at minus 280 degrees Fahrenheit.

Mission Context

• Objective: The ESCAPADE mission, led by UC Berkeley’s Space Sciences Laboratory, aims to study solar wind interactions with the Martian environment to understand atmospheric loss.
• Technology: The Visible and Infrared Observation System cameras, provided by Northern Arizona University, will ultimately be used to detect Martian aurora and analyze surface thermal properties.
• Partners: The mission is supported by Rocket Lab (spacecraft manufacturer), NASA Goddard, Embry-Riddle Aeronautical University, Advanced Space, and Blue Origin.
