Israel's Beresheet spacecraft crashes on MoonWas watching the live feed, I think it is still looping. The comments are hilarious because people can't see the feed is looping BBC already reported the crash over an hour ago

One of the last photos taken by Beresheet of the moon's surface before it crashed[has that NASA Green Cheese color :P
QuoteThe first privately funded mission to the Moon has crashed on the lunar surface after the apparent failure of its main engine.
The Israeli spacecraft - called Beresheet - attempted a soft landing, but suffered technical problems on its descent to the Moon's surface.
The aim of the mission was to take pictures and conduct experiments.
Israel hoped to become the fourth country to land a spacecraft on the Moon.
Only government space agencies from the former Soviet Union, the US and China have made successful Moon landings.
"We didn't make it, but we definitely tried," said project originator and major backer Morris Kahn.
"I think that the achievement of getting to where we got is really tremendous, I think we can be proud," he said.
Prime Minister Benjamin Netanyahu, watching from the control room near Tel Aviv, said: "If at first you don't succeed, you try again."
After a seven-week journey to the Moon, the unmanned spacecraft approached a final orbit at 15km (9m) from the surface.
Tensions were high in the command centre as communications were lost before Opher Doron, the general manager of Israel Aerospace Indurstries' space division, announced there had been a failure in the spacecraft.
"We unfortunately have not managed to land successfully," he said.

Reactions from people watching outside the control room at Israel Aerospace Industries (IAI) site in YehudQuoteThe audience outside had been through a turbulent journey themselves as they watched the first part of the landing go to plan.
As Mr Doron announced that the engine had cut out, groans filled the room.
"We are resetting the spacecraft to try to enable the engine," he said.
The engine came on seconds later and the audience applauded, only for communication with the spacecraft to be lost shortly after. The mission was over.
The project has cost about $100m (£76m) and has paved the way for future low-cost lunar exploration.
Dr Kimberly Cartier, an astronomer and science news reporter, tweeted that she was "sad about how #Beresheet ended" but "proud of the entire @TeamSpaceIL".

ISA - ISRAEL SPACE AGENCY

After eight years of development, Beresheet spacecraft will be launched from Florida's Cape Canaveral on Friday, January 22, 2019 3:45AM IST. If successful, the 160-kilogram unmanned four-legged spacecraft will also be the smallest and cheapest spacecraft to land on the moon. Beresheet, is the creation of an Israeli nonprofit called SpaceIL, collaborating with IAI (Israel Aerospace Industries) and with contribution of ISA (Israel Space Agency) of the Department of Science and Technology.
Beresheet set to touch down in the Sea of Tranquility on April 11.

No updates yet still shows the scheduled launch

So I tune in to watch the Israeli spacecraft attempt to land on the moon knowing full well either they are going to fake it or they are going to crash.
They crashed. Why?
Well I wrote down the final numbers the spacecraft transmitted on TV which were:
at an altitude of 149 meters (450 ft.)
Its speed was 946 meters/second (2100 mph)
Fuel mass 76 kgs. (167 pounds) (28 gallons)
Now I am not a rocket scientist, but...you don't have to be a rocket scientist to figure out that you are not going to slow the spacecraft from 2100 mph to zero speed for landing with 28 Gallons of fuel.
The Israeli announced reason for the crash was 'main engine failure'.
So why did it fail?
It ran out of gas.
How could the Israelis have made such a gigantic error in their moon landing computations so as to run out of gas?
Probably because Israel hasn't figured out that the moon's gravity is 69.71% that of Earths and not the NASA/Newton derived figure of one sixth that of Earth's. So when they got to the moon they found their spacecraft orbiting the moon in one hour instead of two and when they started their descent they were using way more fuel to maintain their predicted descent profile.
And then again maybe they were going to fake the landing like the Chinese did but didn't want to suffer the ignominy the Chinese did so decided that a crash 'with honor' was the better option.
I would appreciate any comments about my figures and whether or not I have made any errors. There are certainly people on FB that are far more knowledgeable than me on orbital mechanics and fuel burn. Thanks.
So looks like the Saudi's are next :P
First Arab Muslim astronaut to lead Saudi space agency amid leadership reshuffle(https://www.abc.net.au/news/image/10670964-3x2-700x467.jpg)
PHOTO: Prince Sultan bin Salman, right, worked with NASA in the 1980s. (NASA: S85-32002)QuoteSaudi Arabia is to get its own space agency, as King Salman bin Abdulaziz Al Saud orders his 62-year-old son, Prince Sultan bin Salman, to lead the organisation.
Prince Salman was the first Arab and Muslim to travel into space in 1985, helping to deploy a satellite for the Arab Satellite Communications Organisation with NASA.
The announcement is part of the first major reshuffle of leadership positions after the controversy surrounding the killing of prominent Saudi journalist Jamal Khashoggi at the Saudi consulate in Istanbul in October.
Many — including the US Senate and CIA — point to Crown Prince Mohammed bin Salman as the person responsible for the assassination, though Riyadh has maintained that these accusations are unsubstantiated.
In the weeks since the killing, Germany has halted arms sales, while a coalition made up of France, Canada, Germany and the US have imposed targeted sanctions on the Saudi elite.
Saudi Arabia's embattled foreign minister, Adel al-Jubeir, who fronted global media after the scandal, has now been replaced by former finance minister Ibrahim al-Assaf.
Mr Assaf was detained briefly in the Crown Prince's anti-corruption crackdown last year but was released within weeks of his detention at Riyadh's Ritz-Carlton hotel last year.
He was cleared of wrongdoing and without making any payment to the state, as many others held in the crackdown had to do.
He is also a member of the board of national oil company Aramco.

Should be interesting because Saudi Clerics say the Sun revolves around Earth
QuoteSaudi Arabian cleric Sheikh Bandar al-Khaibari has claimed that the Earth is stationary and the sun rotates around it in a speech he gave to students at a university in the United Arab Emirates on Sunday. The claims have since been mocked by Twitter users and Cambridge University scientists alike. We take a look at video of the Muslim cleric's attempt to debunk the rotation theory
Muslim cleric says that the earth stands still and the sun goes around the sun.

Hey A51Watcher...
Can you make us a Moon landing film showing that Pegasus one landed on Farside? using Clementine color images should work.
Your grand voyage films are awesome maybe Paulie could help
Then we tell the world we made a successful landing :D
Why would you name your space probe Bearsh*t?
Don't they know bearsh*t is subject to gravity?
:) Howdy do! Your funny Irene.....LOL Good ones lol

Just in case you wanted to know....lol Bereshit.............
It's Hebrew for (In the beginning) along with other variation of the same meaning like (at the start ect...) However I like the name Bearshit better! lol After all it did fall like crap. lol ;D

lol. This is exactly what I was hoping to see when clicked on this thread,a John Lear comment and explanation...perfect!
Thanks John, I hope you see this from your friend Hoss58 [grin]
