Beresheet na orbicie Księżyca BY KRZYSZTOF KANAWKA ON 5 KWIETNIA 2019
(...) Czwartego kwietnia po godzinie 16:10 CEST nastąpił manewr wejścia lądownika Beresheet na orbitę księżycową. Manewr trwał sześć minut i przebiegł prawidłowo, dzięki czemu Beresheet zaczął okrążać Srebrny Glob po eliptycznej orbicie.

The mission was designed, built and launched for around $100 million, and almost all of the funding came from private donors and corporate investments.
“We’ve done it! First privately funded spacecraft in lunar orbit,” tweeted Yoav Landsman, Beresheet’s deputy mission director at SpaceIL. “Feels like the dawn of a new era of commercial space.”
Morris Kahn, a South African-born Israeli billionaire, contributed $40 million of his fortune to the project. Kahn, 89, was at Beresheet’s control center in Israel for Thursday’s critical maneuver.
“We’ve had support from all over the world,” Kahn said Thursday. “NASA has recognized what we’re doing, and the world has recognized what we’re doing, and what we’re doing is we’re pioneering something in space. We’re showing that a small country can actually do an amazing job.”
But more perils remain ahead for Beresheet. Its mission will culminate with a landing April 11 — next Thursday — in the Mare Serenitatis, or Sea of Serenity, region on the upper right part of the moon as viewed from Earth.
“After a challenging journey, we made tonight another Israeli record and became the seventh nation to orbit the moon,” said Nimrod Sheffer, CEO of Israel Aerospace Industries, Beresheet’s prime contractor. “Even before Beresheet was launched, it already was a national success story that shows our groundbreaking technological capabilities. Tonight, we again reach new heights. In the coming week, our talented engineering team will work 24/7 to bring us to an historic event on April 11.”
Beresheet was expected to enter an elliptical, or oval-shaped, orbit ranging between 310 miles (500 kilometers) and 6,200 miles (10,000 kilometers) above the moon’s surface. Several more engine firings during the next week will place Beresheet in a circular 124-mile-high (200-kilometer) orbit in preparation for landing. (...)
