    Israel's private moon mission - Beresheet

    The Israeli Shavit rocket produces less thrust than a Thiokol Shuttle booster. Can they really land a
    dishwasher-size
    object on the Moon cheaply?

    thread title changed from "Israelis to land on the Moon on the cheap?"

    No; the article says so.
    Israel, which has experience in sending spy satellites to the lower orbit, does not have capabilities to launch into space, although the Israeli Space Agency is looking to develop a civilian space programme.

    This is an independent Israeli team entered in the Google Lunar X-Prize competition; if they fly it will be on a US/Russian/European rocket.

    They are still aiming for the moon with SpaceX's help.

    https://www.i24news.tv/en/news/israe...ft-on-the-moon

    Israel announced on Tuesday that it will launch its first lunar mission in December, with the hopes of becoming the fourth country to land a spacecraft on the moon in February 2019.

    Israeli space exploration firm SpaceIL, together with Israel Aerospace Industries (IAI), will launch a spacecraft into orbit via a SpaceX rocket in December, which they intend to land on the moon in February 2019.

    Israeli 2019 Moon landing

    Israeli spaceship scheduled to land on the moon next year

    "Unlike other spacecrafts, which took several days to reach the moon, SpaceIL's spacecraft will take longer. The launcher will release the spacecraft at the height of 60,000 kilometers, and to save fuel, it will enter an elliptical orbit around the Earth until it reaches the moon."

    Has this method of getting to the Moon been used before? How long will it take?

    "Israel's maiden moon launch delayed to 2019"

    https://www.ynetnews.com/articles/0,...368052,00.html

    SpaceX, whose rockets are set to carry the Israeli unmanned probe into space, informs SpaceIL of 'a delay of a number of weeks,' leading to the postponement of the Israeli launch; work on Israeli craft proceeding successfully, says SpaceIL.

    Has hummus been to the moon yet?
    This could prove to be quite a culinary coup for whoever does it.

    Israel's private moon mission - Beresheet

    Historic moon lander mission, and the 1st privately developed craft, has been sent on its journey to the moon by Space X.

    http://www.planetary.org/blogs/jason...-launched.html

    SpaceIL's Beresheet spacecraft is on its way to the Moon following a successful launch atop a SpaceX Falcon 9 rocket from Florida. Liftoff occurred as scheduled on 22 February at 01:45 UTC (21 February 20:45 EST). You can watch a replay of SpaceX's launch broadcast here.
    More information on Beresheet.

    http://www.planetary.org/blogs/jason...to-expect.html

    Launch day is almost here for Beresheet, a small lunar lander built by Israeli non-profit SpaceIL. Liftoff is currently set for 22 February at 01:45 UTC (21 February 20:45 EST), atop a SpaceX Falcon 9 rocket from Cape Canaveral, Florida.

    If all goes well, Beresheet will push free from the Falcon 9 about a half an hour after launch, kicking off a 40-day journey to lunar orbit followed by another week before it actually lands. Thanks to some extremely helpful email exchanges with Yoav Landsman, a SpaceIL senior systems engineer, I was able to put together this handy guide detailing Beresheet's entire mission. Let's get started!

    SpaceIL Beresheet lunar lander (Israel)

    A SpaceX Falcon 9 rocket lit up the night skies over Florida's Space Coast on the evening of Thursday, February 21st. It carried a group of payloads into space, including the first privately funded lunar lander: the Beresheet mission from Israeli company SpaceIL. Liftoff occurred at just after 8:45 p.m. EST (1:45 UT). The Falcon 9 stage one booster that launched the missions also successfully landed on the offshore OCISLY (Of Course I Still Love You) drone ship about eight minutes after liftoff.

    Originally nicknamed Sparrow, Beresheet (Hebrew for the phrase from the Book of Genesis, in the beginning) weighs in at 1283 pounds (582 kilograms), including about 882 pounds (400 kilograms) of propellant. The lander is 5 feet (1.5 meters) high by 6 feet (2 meters) wide. It shares the rocket's nose fairing with Indonesia's Nusantara Satu communications satellite and the U.S. Air Force Research Laboratory's S5 space situational awareness satellite. Both of the satellites are headed towards geostationary orbit.

    A Long Journey Ahead

    The lander's trip to the launch pad was a long one, and it still has a ways to go geostationary orbit will only get the lander a tenth of the way to the Moon. Its journey will take about seven weeks, as the lander slowly raises its orbit for capture by the Moon in early May 2019.

    If successful, Israel will become the fourth nation behind the United States, Russia, and China to make a soft landing on the Moon. India and Japan have also fielded orbiters around the Moon. Tracking stations worldwide will now monitor Beresheet, as SpaceIL controls the mission from company headquarters in Tel Aviv. The mission team will be scouting out the 9.3-mile (15-kilometer) landing ellipse in the Mare Serenitatis (Sea of Serenity) in preparation for landing.

    Is this the same mission mentioned in this thread? It's the same company, that much I could quickly find.

    "SpaceIL lunar lander makes first post-launch maneuvers"

    SpaceIL lunar lander makes first post-launch maneuvers

    As an Israeli-built lunar lander makes its first post-launch maneuvers, a Japanese company announced new partnerships in its plans to mount missions to the moon.

    SpaceIL announced Feb. 24 that its Beresheet lander performed its first maneuver since being placed into a supersynchronous transfer orbit by a Falcon 9 Feb. 21. The 30-second burn of the spacecraft’s main thruster increased the perigee of its orbit around the Earth to 600 kilometers.

    "Israeli lunar lander's maneuver nixed following glitch"

    http://www.israelnationalnews.com/News/News.aspx/259594

    Israel’s Beresheet spacecraft, an unmanned vehicle slated to land on the moon, missed a scheduled maneuver Monday night, after the spacecraft’s computer system suffered an apparent glitch, resetting itself unexpectedly.

    In a statement Tuesday morning, SpaceIL and Israel Aerospace Industries (IAI) engineers said they were investigating the malfunction, but said that other than a known problem with the navigation system’s star tracker, the Beresheet’s systems were all functioning properly.

    It's gotten further than most of the U.S. Pioneer lunar spacecraft, can't complain.
    There is something fascinating about science. One gets such wholesale returns of conjecture out of such a trifling investment of fact.

    Well which was it the first burn was executed and the second aborted or was the first post in error?

    Sounds like the second maneuver was aborted. The first took place on Feb 24, the missed maneuver was Feb 25.

    The missed burn was intended to raise the apogee of Beresheetís orbit to 73,000 miles from Earth. Having missed this window, the team will need to adjust its plans for the rocket. The original plan called for five burns, with a sixth engine firing to swing the probe into lunar orbit, before braking for landing. It isnít clear yet what caused the computer to reset just before burn or whether the issue can be solved. Presumably it can.

    That is correct. India's MOM also had a glitch on one of its burn, but subsequent burns went okay, and it reached Mars.

    It seems as though the Israelis have now corrected the computer shut-down fault.

    Is there anything novel about the Israeli method of lunar capture, or has it been used before?

    Similar to SMART-1, I believe.

    Beresheet takes a selfie with earth as background.

    https://en.globes.co.il/en/article-i...ace-1001276761

    Israel's Space IL lunar spacecraft Beresheet has taken a selfie in outer space, 37,600 kilometers from Earth, using a special selfie camera with which it will snap itself after landing on the moon on April 11. The selfie, which will be taken next month will prove that Israel has become the fourth country to land on the Moon after the US, Russia and China.
