The first privately funded mission on the Moon will try to land on the surface of the Moon today.
The Israeli spacecraft, Beresheet, will try to touch it before photographing and conducting experiments. now it has only been achieved by government governments from the former Soviet Union, the United States and China.
Mission cost about $ 1
Beresheet, which is Hebrew for the "beginning", is a joint project of SpaceIL, a privately funded Israeli nonprofit organization, and Israel Aerospace Industries.
Morris Cahn, founder of SpaceIL, told BBC News: "The landing will be extremely difficult."
"But we have good engineers, the spacecraft has responded well to our instructions for the past two months.
I'm pretty sure but a little nervous.
Why did Beresheet hit the moon for several weeks?
In cosmic terms, the Moon is a simple jump from Earth, and most missions take several days to get there.
But the Beresheet mission, launched February 22 from Cape Canaveral, Florida, took several weeks to its destination.
Her journey took a series of constantly expanding orbits around the Earth. April 4th to the orbit of the moon.
The average distance to the moon is 380,000 km. – Beresheet traveled more than 15 times for this distance.
And the main thing is that it has led to cost.
Instead of sitting alone on a rocket that would set her on an ideal trajectory to the moon, she exploded on the SpaceX Falcon 9 rocket along with the satellite and
The sharing of space rides greatly reduced the launch cost – but this meant that the spacecraft had to go on a much more complicated route.
How difficult is it to land?
Moon landing on the moon will be a major issue for Israeli spacecraft.
The key to his success will be the British engine developed by Nammo in Westcott, Buckinghamshire
. Beresheet on its final descent.
A spaceship of 1.5 m in height must quickly reduce its speed, so the final shooting of the engine actually crashes into the brakes, hoping that the ship gets into a light stop.
Rob Westcott, a senior engine engineer at Nammo, said: "We have never used an engine in this application."
"The big problem is the fact that the engine must be turned on and become very hot, then turned off for a short period the time when all that heat stays in its thermal mass, and then lights up again, very precisely and very accurately, so that it slows down the craft down and lands very much on the surface
The process should take about 20 minutes.
All controls for this purpose have been downloaded and will be run autonomously – the mission control will need to be monitored.
What will be
His first job is to use his high resolution cameras to make several photos – including selfie – and then send them back to Earth.
Then he begins to measure the magnetic field of the spot on which he landed, an area known as Mare Serenita
Monica Grady, a professor of planetary and space science at the Open University, said: "They will look very carefully at the landing site, which will help determine how the magnetic measurements of the moon fit into the geology and geography of the moon, which is really important to understand how the moon is formed.
Lander also carries a reflector from NASA, which helps scientists make accurate measurements of the distance between Earth and the Moon
Mission is not will last until Maybe it's only a few days on Earth.
The temperatures on the Moon are remarkable, and when the Sun rises, it is unlikely that the space vehicle will survive heat
How important is this mission?
For 60 years of exploration of space, only three countries have fallen to the moon.
The former Soviet Union reached its first landing with its spacecraft Luna 9 In 1966, NASA followed this, getting the first people to the Moon in 1969. Then the Chinese spacecraft Change-4 touched the farther side of the moon earlier this year.
If their landing works, Israel will be the fourth nation to join this elite club.
But this is a low price – and the fact that this mission is not funded by a large space agency – it does make this mission stand out.
Its cost of $ 100 million is a fraction of what is usually spent on a similar enterprise.
And Beresheet is not the only one in conducting inexpensive lunar studies.
Her origin is Google Lunar XPrize, an international call offering $ 20 million for the first privately designed spacecraft to land on the moon. [TheFoundationisaccountablefora$4500millionExcellencePartnership)andotherparticipatingCommitteeswillcontinuetheireffortstogrowuptotheMonth
