Exact adjustment of the date of the meeting with the moon. The engineering team of SpaceIL and the Aerospace Industry performed the maneuver during which the engines operated for about 72 seconds. The teams are now checking the results of the maneuver to know if another adjustment maneuver will be required before the "capture the moon" maneuver expected to be carried out this Thursday
On 1/4/2019 at 09:00, the Beresheet spacecraft successfully performed another maneuver whose goal is to precisely match the date of the meeting with the moon. The engineering team of SpaceIL and the Aerospace Industry performed the maneuver during which the engines operated for about 72 seconds. The crews are now reviewing the results of the maneuver to know if another adjustment maneuver will be required before the "capture the moon" maneuver.
On Thursday, 4/4/2019, Beresheet will perform the moon capture maneuver, one of the critical points in the entire journey. It's a complex maneuver that aims to be captured by the moon's gravity and start circling it towards landing.
The SpaceIL association and the Aerospace Industry are preparing for the "capture the moon" maneuver by practicing different scenarios, performing simulations and in-depth tests in the hybrid laboratory.
Also, yesterday (Sun., 31/3/2019) the Beresheet spacecraft passed near the Earth, it approached to an altitude of 1,700 km. During the climb, the engineering team managed to take a rare picture of the Earth from a distance of about 16 thousand km. In the picture you can see the Arabian Peninsula and Northeast Africa, and the rain clouds that hid Israel on that particularly stormy day.

Conan, it is true that the Americans lost a satellite because they did calculations in pounds instead of kilos
But here it is Israel. If she doesn't reach the moon, then at least she can be broadcast on all channels and say "I told you so"
Question: We all heard that right before her second maneuver, the computer was rebooted, which caused the maneuver to be postponed for about 24 hours - therefore if they rely on the original calculations of the parameters in the current engine operation - they will actually send the Genesis not to the moon, but bring her to the point where the moon was 24 hours ago Hours!
If so, before this maneuver of Genesis (on April 1.4.2019, XNUMX, which was also the last in its orbit around the Earth) - was the change in the position and trajectory of the spacecraft taken into account - and new calculations were made, such as the angle and duration of the engine activation - and indeed a different maneuver was performed from the original maneuver (which calculates time Rab before its launch)?
In my opinion, one should choose one of the following two options: 1) performing the maneuver with the new values after the recalculation of the Genesis trajectory following the delay in performing its second maneuver, or 2) correcting the trajectory of the Genesis by several short activations of the engine during the journey after this maneuver (which was conducted without the correction in the parameters and position due to the failure of her second maneuver) until the moment of the "capturing the moon" maneuver?
I believe and predict that the wristwatch will be the only ruler in our lives in the future in performing the tasks of opening and moving the car as well as turning the television on and off as well as opening and closing the house the apartment starting the car our doctor to check temperature and blood as well as all the sensations and pains in the body and he will also heal us the watch by giving medical advice I expect success for the wristwatch Phenomenal to manage our lives at every level. I am surprised that until now there are no agreements and connections between entrepreneurs on managing and developing the ultimate watch franchise because the revenues from this will be huge and enormous.
