A private Israeli Moon mission

Beresheet (Hebrew: בראשית), which means "in the beginning," is a private mission to the Moon by Israeli non-profit SpaceIL. Built to win the now-defunct $20 million Google Lunar XPrize, Beresheet was meant to inspire more Israelis to pursue STEM careers.

In addition to providing high-resolution imagery from the surface, Beresheet will measure the magnetic field at its landing site in Mare Serenitatis, which has magnetic anomalies detected by Kaguya, Lunar Prospector, and Luna 21 mission. Understanding the Moon's magnetism teaches us about its history. While Earth has a global magnetic field caused by the continued churning of liquid metal near the core, the Moon does not. But 3.6 billion years ago, the Moon had a magnetic field just as strong as Earth's. 

When new-forming rocks solidify from their melted states, they lock in traces of the ambient magnetic field at the time. By looking at the ages of different regions and the strength of the magnetic field embedded in rocks, scientists can piece together the Moon’s history.

Landing site

Beresheet is targeting the northern part of Mare Serenitatis. The landing site roughly forms a triangle with previous lunar landers, with Beresheet at the top, Apollo 15's landing site in Mare Imbrium to the southwest, and the Soviet Union's Luna 21 lander and Lunokhod 2 rover to the southeast. 

Mare Serenitatis varies in brightness from a light-toned center to a darker outer edge. Initial lunar observations and crater mapping led scientists to believe the outer ring was younger, but on-the-ground observations by Apollo 17 showed the story was more complicated, with the ring varying in age. 

Orbital measurements of the Moon's magnetic field from Kaguya and Lunar Prospector showed magnetic fluctuations in the northern part of Mare Serenitatis, which guided selection of a regionally smooth landing site there. By studying the magnetic field of rocks in this area directly, scientists will be able to further piece together the story of the Moon's history.

Spacecraft instruments and tools

Imaging system: Beresheet's camera system consists of six color (RGB), 8-megapixel, Imperx Bobcat B3320C cameras with Ruda optics. They have 60-by-80-degree field of views and resolutions of 2488 by 3312 pixels. Five are positioned along the circumference of the spacecraft’s circular deck to create a full panorama after landing, and one “selfie” camera with a shorter focal length looks inward toward a plaque with the Israeli flag on the deck.
