six weeks after blastoff from the Florida Space Coast, Israel’s privately built Beresheet Moon
lander fired its braking thrusters and was successfully captured into lunar
orbit this morning, Thursday, April 4, setting the stage for a thrilling
touchdown on Earth’s nearest neighbor one week from now on April 11.

country to send a probe into lunar orbit- and for commercial space activities as
this tiny probe is the first privately funded mission to reach the Moon.

If the “Lunar Capture” maneuver had failed Beresheet would have gone into
a useless solar orbit and never enter orbit around the Moon and thus the
mission would have ended.

funded and built by Israeli nonprofit SpaceIL and Israel Aerospace Industries
(IAI). It marks Israel’s first lunar mission and also counts as being the
world’s first privately funded lunar mission.
If all continues to go well lunar touchdown is scheduled for April
11 at Mare Serenitatis (Sea of Serenity) on the Moon’s
northern hemisphere on the upper right side as seen from Earth.
To date Beresheet has now performed the lunar capture firing and seven prior thruster firings and traveled over
5.5 million km (3.4 million mi.) in its long looping orbits around Earth edging
closer to the Moon and has another million to go before the landing.
During its voyage to date it orbited Earth 12.5 times on ever expanding long
looping traverses: seven at an altitude of 70,000 km (nearly 44,000 miles), two at an
altitude of 131,000 km (nearly 814,000 miles), two at an altitude of 265,000 km
(nearly 165,000 miles) and 1.5 at 420,000 km (over 260,000 miles).
