The Israeli team SpaceIL will attempt to land the country's first moon lander, called Beresheet, on the Sea of Serenity on the moon and you can watch it live today, courtesy of a SpaceIL webcast. The webcast will begin at 2:45 p.m. EDT (1845 GMT), with Beresheet's landing expected for some time between 3 and 4 p.m. EDT (1900-2000 GMT).

Beresheet is a $100 million privately developed lander originally developed by SpaceIL to compete in the $30 million Google Lunar X Prize, an international contest that ended in 2018 with no winners. SpaceIL teamed up with Israel Aerospace Industries to continue the project, leading to today's landing attempt.

SpaceIL is controlling Beresheet from a control center in Yehud, Israel. The spaceraft launched in February on a SpaceX Falcon 9 rocket and has been steadily raising its orbit to reach the moon.

Last week, Beresheet successfully entered orbit around the moon.






NASA Twins Study Teleconference

NASA will hold a live teleconference at 2 p.m. EDT (1900 GMT) to unveil the latest discoveries from its Twins Study, a project that followed the world's only identical twin astronauts - Scott and Mark Kelly - during the space agency's Year in Space mission. During that mission, Scott Kelly spent nearly a full year on the International Space Station while his brother remained on Earth. Scientists followed both astronauts to compare how Scott's body changed from his twin's during spaceflight.

From NASA:


ASA will host a media teleconference at 2 p.m. EDT Thursday, April 11, to share the results of a study – embargoed by the journal Science until that time – evaluating identical twin astronauts Scott and Mark Kelly. A Reddit iAMA will follow the media teleconference at 4 p.m.

The briefing participants are:

The Twins Study is helping scientists better understand the impacts of spaceflight on the human body through the study of identical twins. The Twins Study research encompassed 10 separate investigators who coordinated and shared all data and analysis as one large, integrated research team. Retired astronaut Scott Kelly spent 340 days in low-Earth orbit aboard the International Space Station while retired astronaut Mark Kelly, his identical twin, remained on Earth. The twins’ genetic similarity provided scientists with a reduced number of variables and an ideal control group, both important to scientific investigation.

Good to know that 137 billion the US has given them has freed them up from just stirring shit up and slaughtering people to go to the moon.
 
I would watch if it was Israel going to the moon.

Their war crimes and robbery of neighboring
lands would end, there would be peace in the
region.
Trump could spend the Israel Welfare cash on
America and MAGA.

How hard was it to land?

A controlled landing on the lunar surface was the major challenge for the Israeli spacecraft.

The engine was British-built, developed by Nammo in Westcott, Buckinghamshire. It provided the power to get the spacecraft all the way to the Moon, but it also took Beresheet on its final descent.

The 1.5m-tall spacecraft had to rapidly reduce its speed, so a final firing of the engine in effect slammed on the brakes, hoping to take the spacecraft to a gentle stop.

Before the landing, Rob Westcott, senior propulsion engineer at Nammo, said "We've never used an engine in this kind of application before".

He said the big challenge would be "the fact that the engine is going to have to be switched on and get very hot, then switched off for a short period of time when all that heat is remaining in its thermal mass, and then fired up again, very accurately and very precisely such that it slows the craft down and lands very softly on the surface on the Moon."

That landing process took around 20 minutes. All of the controls for this were uploaded and performed autonomously with mission control watching on.

The 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.

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.

Beresheet spacecraft: 'Technical glitch' led to Moon crash

Preliminary data from the Beresheet spacecraft suggests a technical glitch in one of its components caused the lander to crash on the Moon.

The malfunction triggered a chain of events that eventually caused its main engine to switch off.

Despite a restart, this meant that the spacecraft was unable to slow down during the final stages of its descent.

The Israeli spacecraft was the first privately funded probe to attempt a soft landing on the Moon.

The engineering team at SpaceIL and Israel Aerospace Industries (IAI) said that the first technical issue occurred 14km above the lunar surface. This would have been moments after it sent a selfie of its descent.

The final telemetry reading from the spacecraft revealed that 150m above the lunar surface, the spacecraft was moving at about 500km/h (300mph). At this speed a crash landing was inevitable.

SpaceX nails triple booster landing after satellite delivery

Elon Musk's SpaceX Falcon Heavy launched from NASA’s Kennedy Space Center in Florida carrying a satellite into orbit for Saudi Arabian company Arabsat.

As well as having its first commercial payload, it was also the first time the three lower boosters of the rocket returned to Earth successfully.

The rocket is part of a growing number of launch services at SpaceX, which includes the Crew Dragon that docked onto the International Space Station in March.
 
It approached the Sea of Serenity and thought it saw the U.S.S Liberty.
