1) Today at 08:34 Israeli time #Beresheet successfully carried out another maneuver around the #Moon. The engines operated for around 78 seconds, burning around 11.7 kg of fuel. Beresheet entered a circular orbit of 200 km above the Moon and will circle it once every two hours.

Beresheet lunar landing site revealed
03 Apr 2019

The selection criteria for the sel ected lunar landing site focused on ensuring a safe landing, searching for sites with relatively few craters, exposed rocks or steep slopes within the landing area that could jeopardize the touchdown.

​(Communicated by the Weizmann Institute of Science Spokesperson)

The main scientific instrument on board the Israeli Beresheet spacecraft, the SpaceIL Magnetometer (SILMAG), has now been successfully turned on in space and data returned to Earth. After its successful launch, Beresheet is circling Earth on its journey to the Moon. Prof. Oded Aharonson of the Weizmann Institute of Science is heading the team that is currently analyzing the SILMAG information to evaluate the health and accuracy of the instrument in space, as well as recording the magnetic signature of the spacecraft itself, which will then be subtracted fr om the measurements made on the Moon.

Measuring the magnetism of lunar rocks will enable researchers to address outstanding questions about the Moon: how it acquired its magnetic field, and when in its history this occurred.

Aharonson and his team of scientists, working with the SpaceIL engineers, have identified a landing site for the Beresheet lander. The selection criteria focused on ensuring a safe landing, searching for sites with relatively few craters, exposed rocks or steep slopes within the landing area that could jeopardize the touchdown. In addition, the scientists searched for a location on the Moon where the crust is magnetic, so as to allow the magnetometer on board the spacecraft to carry out its investigation.

The landing site was selected together with Prof. Jim Head of  Brown University​, a member of the SpaceIL team who worked with the NASA Apollo program on landing site selection, among other things. "On the basis of our experience with Apollo, the Serenitatis sites favor both landing safety and scientific reward," he said.  

The chosen site is located in the northeastern part of Mare Serenitatis, a few hundreds of km east of the Apollo 15 landing site and a similar distance northwest of the Apollo 17 site. Three optional landing sites (primary and two backups) were identified. The terrain in these locations is composed of material characteristic of ancient mare surfaces on which successful landings have been made (most recently Chang’E 3 and 4). "Lunar magnetism has been an enigma for decades. It is a privilege to be part of this mission that's taking one more step towards solving it," said Aharonson.

SpaceIL reports that its Beresheet lander just completed its final orbital maneuver before tomorrow’s landing, and is now in an elliptical orbit with a periapsis ion 15-17 km and apoapsis of 200 km.

We are ready for landing! Following today’s maneuver Beresheet is again in an elliptical orbit, with its perilune (the closest point to the Moon) only 15-17 km from the moon’s surface and its epilune (the farthest point from the Moon) at 200 km.

The maneuver was performed on the far side of the Moon with no real time communication. The spacecraft’s engines were activated for 32 seconds & consumed 5 kg of fuel. Having completed the maneuver, Beresheet will continue to orbit the Moon in an elliptical orbit every 2 hours.

Private Moon Lander with NASA Science Aboard May Soon Touch Down on Surface

Following a nearly two-month journey, the first private robotic spacecraft to attempt a Moon landing is on track to meet its goal on April 11, and NASA is a partner in SpaceIL’s Beresheet mission. The landing attempt comes on the heels of the agency’s own charge fr om the president to accelerate its plans to send astronauts to the surface of the Moon by 2024.

“NASA wants to conduct numerous science and technology demonstrations across the surface of the Moon, and we will do so with commercial and international partners,” said Steve Clarke, deputy associate administrator for Science Mission Directorate at NASA Headquarters in Washington. “Supporting SpaceIL and the Israel Space Agency (ISA) with this mission is a prime example of how we can do more, together. We’re hoping a successful landing here will set the tone for future lunar landers, including our series of upcoming commercial deliveries to the Moon.”

In addition to providing access to the agency’s Deep Space Network to aid in communication during the mission, NASA launched a navigation device on Beresheet, SpaceIL’s Moon lander, which will provide lunar surface location details that can be used by future landers for navigation. Beresheet is carrying a NASA instrument called a laser retroreflector array. Smaller than a computer mouse, it features eight mirrors made of quartz cube corners set in an aluminum frame. This configuration allows the device to reflect light coming fr om any direction back to its source.

NASA’s Lunar Reconnaissance Orbiter or LRO, will attempt to take scientific measurements of the SpaceIL lander as it lands on the Moon. LRO will try to use its own instrument called a laser altimeter, which measures altitude, to shoot laser pulses at Beresheet’s retroreflector and then measure how long it takes the light to bounce back.

By using this technique, engineers expect to be able to pinpoint Beresheet’s location within 4 inches (10 centimeters).

This simple technology, requiring neither power nor maintenance, may make it easier to navigate to locations on the Moon, asteroids, and other bodies. It could also be dropped from a spacecraft onto the surface of a celestial body wh ere the reflector could help scientists track the object’s spin rate or position in space.

“It’s a fixed marker you may return to it any time,” said David E. Smith, principal investigator of the Lunar Orbiter Laser Altimeter, or LOLA, on the LRO.

The ISA and SpaceIL will also share data with NASA from another instrument installed aboard the spacecraft. The data will be made publicly available through NASA’s Planetary Data System.

Beresheet launched Feb. 21 on SpaceX Falcon 9 rocket from Cape Canaveral Air Force Station in Florida. The spacecraft completed a maneuver April 4 called a lunar capture that placed it in an elliptical orbit around the Moon, setting the stage for its first landing attempt on April 11. Beresheet is targeting an area known as the Sea of Serenity (Mare Serenitatis in Latin), which is near wh ere NASA’s Apollo 17 astronauts landed in 1972.

The president’s direction from Space Policy Directive-1 galvanizes NASA’s return to the Moon and builds on progress on the Space Launch System rocket and Orion spacecraft, collaborations with U.S industry and international partners, and knowledge gained from current robotic assets at the Moon and Mars.

Израильский аппарат "Берешит" совершил последний маневр и готов к прилунению

Прилунение должно произойти вечером в четверг, отметили в компании SpaceIL

ТЕЛЬ-АВИВ, 11 апреля. /ТАСС/. Израильский космический аппарат "Берешит" совершил в среду вечером последний маневр для выхода на новую орбиту вокруг Луны и готов к предстоящему поздно вечером 11 апреля прилунению. Об этом сообщила в Twitter израильская компания SpaceIL, которая руководит миссией.

"Двигатели космического аппарата были активированы в течение 32 секунд и использовали 5 кг топлива. Завершив маневр, "Берешит" продолжит вращение вокруг Луны по эллиптической орбите, совершая оборот каждые ldf часа, - указали в SpaceIL. - Мы готовы к посадке!".

Прилунение "Берешит" должно произойти с 22:00 до 23:00 мск четверга. "Надеемся, что наше прилунение поможет человечеству сделать еще один шаг на пути к освоению космоса", - отметили ранее в SpaceIL.

Управление аэропортов Израиля включило в четверг в свое электронное расписание на 22:00 (время совпадает с московским) прилунение аппарата "Берешит".

"Космос, Луна. 11 апреля, 22:00. Не окончательно", - указано в онлайн-табло Управления аэропортов сразу после прибывающего в 21:55 рейса из Стамбула и перед прилетающим в 22:00 самолетом из Мадрида. Израильская SpaceIL

21 февраля компания SpaceX вывела "Берешит" на траекторию полета к Луне. На лунную орбиту с земной израильский аппарат перешел 5 апреля. До этого он облетел нашу планету 12 раз на высоте 70 тыс., 131 тыс., 265 тыс. и 410 тыс. км, проделав в общей сложности путь в 5,5 млн км.

On the left, the engine sub system. One center main engine surrounded by eight smaller engines. On the right is the critical altitude and laser display. If the laser turns on and the altitude measures below 50 nautical miles there’s a high probability of a successful landing
