Update - main engine stopped working, probably a crash landing

A detailed update article on the crash event at this link

Five minutes before the expected landing the main engine stopped working for long seconds. And the connection with the spacecraft is also loose. A feeling that we did not land in the best way

The Bereshit spacecraft is approaching its destination in almost exact coordination with the route planned for it. This is the figure given about two hours before the planned landing, which is expected at 22:255, in an interview given by the project manager on behalf of the Aerospace Industry to the website Hadaan
The director of the Israel Space Agency, Avi Blasberger, was also interviewed by the site and said "we are all excited."
In response to the question of whether he is not afraid of disappointing the public in the event of a landing malfunction, Blasberger said: "Most of the mission has already been completed. We are the seventh country to reach the moon. The spacecraft was captured by the moon and is orbiting the moon. We hope that the landing will also be successful. So far it's going well, it will continue to go well."
It's not like the Blaumelech canal, one madman started digging and everyone joined in the success?
Blasberger: "In many cases we need crazy people, thanks to whom we can move forward, Elon Musk was also said to be crazy. At first it seemed crazy, little by little it was managed in a better way, and now it is a project for everything. As mentioned until now everything has gone well, we have passed most of the challenges, there is one more challenge left which I hope will also pass safely and Israel will be the fourth country to land on the moon. In any case, we are the seventh country that has already reached the moon.

Update from this morning: how do we know that the spacecraft landed on the moon, looking at it on the control screen?

The members of the SpaceIL and IAI engineering team worked tonight on the final calculations after last night's successful maneuver of the Beresheet spacecraft and continue to prepare the command files that will be sent to the spacecraft.

Yariv Bash, who jointly initiated the project with Kafir Demari and Jonathan Weintraub, published this morning the instructions for watching the launch. Courtesy of Prof. Yitzhak Ben Israel, Chairman of the Israel Space Agency.

"The spaceship will start performing the landing maneuver fully automatically about 15-20 minutes before touching the ground. The landing will not be controlled from the country with a rudder or joystick, but through a command file sent from the country and the spacecraft then performs everything by itself. From this moment on we can only cross our fingers, we don't even have enough fuel to cancel the landing."

"Hopefully, during the landing, we will get a picture or two of very low quality from the road, it depends a little on the communication with the spacecraft. Better quality photos - will be received only 10 minutes or even an hour after landing. Video - will probably be received only the next morning. Now for the critical part - the landing itself. The picture below is of the display screen we will all see this evening. (Maybe it will change a little, they are still working on it, after all it is an Israeli spaceship...)"

"The red square in the picture shows the communication status with the spacecraft. If there is communication the square will be green (green is good). Basically, how do we know if we landed safely? If this square stays green even after landing and doesn't turn red like in the attached picture. "

"How will we know we've landed? Do you see to his left the square of the height? It will slowly approach 0 height. At a height of about 5 meters above the ground we should reach 0 speed, then turn off the engines and fall for 2.5 seconds gently to the ground (the Moon's gravity is one sixth that of the Earth). You can see the speed in the two squares of the Velocity.
That is, if you see that the altitude has reached 0 or close, and a few more seconds have passed and the telemetry is green - you can breathe easy. In addition, the circle on the left side should be colored light blue (or green) as soon as the landing is completed."

In addition, on the right side you can see the condition of the 8 small engines, and the big engine in the center. While the engines are running, they are colored orange. It may flash due to momentary communication (telemetry) issues, so don't panic if that's what's happening 🙂

More options:

1. It is possible that the spaceship will land on its side because of a rock or a crater - not so bad! As long as we communicate with the spacecraft, we will be able to download the video and photos (we have 6 cameras) and we will get beautiful photos anyway.
If it lands so that the solar panels don't face the sun (on the side, let's say) - then there will probably only be pictures and we won't have enough time to download a video\ before the battery runs out.
2. If you land and the telemetry is red - don't panic - take a deep breath, and you can see how the amazing team of IAA and SpaceIL deal with it calmly and professionally.
It is possible that this is a communication problem of the ground stations or from the direction of the spacecraft. The teams have gone through all the possibilities, and we will try to overcome this as well. And anyway, we reached the moon 🙂

• The Bereshit spacecraft performed a final maneuver before landing
• "We have reached a parking orbit around the moon"
• At the beginning the spaceship descended and approached the moon
• The Beresheet spacecraft descended into a circular orbit at an altitude of 200 km above the surface of the moon; Land on Thursday evening
