ARTEMIS Mission to Earth's Moon

Goals: ARTEMIS stands for "Acceleration, Reconnection, Turbulence and Electrodynamics of the Moon's Interaction with the Sun." This mission is made up of two probes P1 and P2 which were originally members of the successful mission THEMIS in Earth orbit studying Earth's aurora, but were redirected to the Moon in an effort to save the two probes from losing power in Earth's shade. Through this new mission scientists look to learn more about the Earth-Moon Legrange points, the solar wind, the Moon's plasma wake and how the Earth's magnetotail and the Moon's own weak magnetism interact with the solar wind.

Accomplishments: Both probes have arrived at their initial destination: ARTEMIS-P1 is in about-Moon orbit (called an Earth-Moon libration orbit) at the L2 Lagrange point, and ARTEMIS-P2 is in about-Moon orbit at the L1 Lagrange point.

Fast Facts
ARTEMIS Facts ARTEMIS-P1 and P2 were originally two members of a quintet of identical Earth orbiting probes, called THEMIS (THEMIS' launch image right) studying Earth's aurora.

ARTEMIS is the first spacecraft to explore the Earth-Moon Lagrange points and is the first two-satellite mission to the Moon.

Findings by ARTEMIS may help to further research in clean renewable energy.
