An Israeli non-profit affiliated with the local hi-tech and research communities is planning to launch a spacecraft to the moon as an educational endeavor.

By: Batya Jerenberg, World Israel News

The SpaceIL organization announced Tuesday that it will be sending a small, unmanned spacecraft to the moon in December, with an expected landing date of February 13, 2019.
It will be launched on a SpaceX missile from Cape Canaveral, Florida, which will release its history-making cargo 60,000 kilometers from the moon. The spaceship will go around the Earth in an ever-widening, elliptical orbit that will eventually enable it to cross paths with the moon.
At that point, it is supposed to fire its engines in order to slow down and get into a lunar orbit, eventually landing gently on the rocky surface.
“It’s a small, smart spaceship,” said SpaceIL CEO Dr. Ido Anteby. “It’s a meter and a half by two meters, and will weigh 600 kg. at takeoff. Most of its weight is fuel, and when it lands it will [only] weigh 180 kg. It will be in contact with ground stations all over the world; we’ll be in radio contact with it throughout its trip.”
Its first task will be to plant an Israeli flag on the surface and then take still pictures and video. It is expected that the “mission” will wrap up in a mere two days.
Established in 2010 by three Israeli engineers, the nonprofit organization started building the four-legged machine about two years later. They were attempting to win the $20 million Google Lunar X competition for a non-government to land an unmanned spacecraft on the moon, take pictures and video, and travel 500 meters on, above or below the surface. In the event, they reached the finals, but at the end there was no winner as none had met the requirements and deadline in time – but they decided to “go for it” anyway.

Fingers crossed all goes well, בהצלחה

Israel is about to launch its first attempt to land on the Moon.
The Beresheet robot is a privately funded venture that aims to land and hop across the lunar surface.
It's a challenging prospect. Only government space agencies from the US, Russia and China have previously managed soft touchdowns.
The 1.5m-high, 585kg Beresheet will begin its mission with a ride to Earth orbit on a SpaceX Falcon 9 rocket from Cape Canaveral in Florida.
Once ejected from this vehicle, the robot will then use its British-built engine to propel itself to the Moon. The journey will take over two months to complete.

About 58000km slant range at the time of plot. Fades about every 7 mins (see waterfall) due to craft rotation.

Interesting article, thanks, especially this "Engineers are only in contact with the spacecraft for about half an hour every four hours" . On 23rd feb it was losing lock and re-locking much of the time: Satellites Community - Beresheet Lunar Probe When I last listened, a couple of days ago, it was still rotating which must make it hard to keep lock. I couldn't find it yesterday despite the Space-track TLEs having been updated.

The above link causes all sorts of trouble on the iPad, cookie access page that covers the whole screen and cannot be removed, plus third party links.

I can't see that, I'm running Vivaldi on OSX with Ghostery & Ublock Origin. I can see loads of things have been blocked. Screen capture added

At about 122000km, probably not passing data. Still fading indicating spin rate of about 1 every 7 minutes.

At about 100000km. Frequency jump at stat of waterfall, 16kHz sidebands present, possibly in communication

Now in orbit around the Moon with landing scheduled for Thursday at around 19:30GMT

Plot shows it is still spinning. The Doppler change, when locked to a ground station, is twice the rate compared to the unlocked state.

Maybe the plan is just to screw itself down a couple of feet into the lunar regolith :D

Sad end
19:18:40ish IMU fault announced and LoS, then re-started but dog-leg in Doppler shows all's not well.
19:23:01 The End

@Analoguesat thanks. 1.2m dish 1dB NF LNA. Here's the braking manoeuvre:

Well I do not call it failure at all, the fact that such a tiny country, and a privately funded operation to boot managed to become the 7th country in the world to orbit the moon and the fourth to actually reach the moon. Look how many attempts spacex had before they got their system to work. It is a great shame it did not land and carry out the program of experiments however it will not be too long before the 2nd attempt is made
