(JTA) — He’s spent eight years trying to land a spacecraft on the moon, but when Yonatan Winetraub stood on the launchpad this month at Florida’s Cape Canaveral, he was still in shock.
“I stood right next to the rocket, and it’s pretty big,” Winetraub said in a phone interview Wednesday. “In the video, you don’t see how big the rocket is and how powerful it is. But when you stand up close it’s pretty powerful.”
If Winetraub sounds like a kid marveling at the thought of space travel, that’s because he kind of is. He and two friends, all in their 30s, are on the verge of doing something extraordinary: They intend to make Israel the fourth country to land a spacecraft on the moon. Only the United States, the Soviet Union and China have done it.
Winetraub and his partners, Kfir Damari and Yariv Bash, aren’t doing it with billions of dollars from a superpower government. In 2011 they co-founded SpaceIL, an Israeli nonprofit that has a budget of $100 million — a pittance in the space biz. If their mission is successful, it would be the first time any private spacecraft landed on the moon, at lower cost and with a smaller craft than previous landings.
“Kfir, Yariv and myself sat in a bar in a suburb of Tel Aviv and thought, ‘Why not get to the moon?’” Winetraub said at a news conference Wednesday. “I always thought we’re going to get to the moon, but now it’s actually happening, and it’s quite incredible.”
SpaceIL’s squat, circular, three-legged craft is roughly the size of a compact car: 5 feet tall, 6 1/2 feet in diameter and weighing about 1,300 pounds, most of which is fuel. At 8:45 p.m. Eastern time Thursday, barring bad weather or unforeseen problems, the craft will launch into space from Florida hitched to one of Elon Musk’s SpaceX rockets. Winetraub called it the “Uber of space travel.”
More like UberPool, the car pool option: Whereas Apollo 11’s 1969 trip to the moon took three days, SpaceIL’s will take about two months. That’s because it’s riding shotgun on another rocket and cannot propel itself directly to the moon. Instead it has to use orbiting to align itself, only meeting up with the moon at the beginning of April.
About four minutes after launch, the SpaceIL craft, named Beresheet — Hebrew for “Genesis” — will separate from the rocket. It will send a first communication to SpaceIL’s ground control in the central Israeli town of Yehud and go into orbit around the Earth. Over the course of about a month-and-a-half it will hurtle through space at a maximum speed of more than 22,000 miles per hour. Its thrusters will push the craft in progressively wider and wider orbits around the Earth, and closer to the moon’s orbit.
Then it will enter one of the riskiest steps of the mission.
Once it gets near the moon, the craft must suddenly slow down enough to be pulled into orbit around the moon. If it goes too fast, it will pass right by, speeding directly into space. Then, after about a week of traveling around the moon, the craft will slow down again, dropping toward its landing spot on the Sea of Serenity. About 16 feet up, it will cut the engine entirely and free-fall to the moon’s surface, making a soft landing.

SpaceIL’s founders are confident that the mission will be successful. But Winetraub acknowledged that it’s fraught.
“There are many things that can go wrong and only one thing that can go right,” he said. “You really can’t test everything. The atmosphere is different on the moon, the gravity is different on the moon, so you have to have some simulations, some educated guesses about how it’s going to work.”
There were early hiccups. At the news conference, Winetraub wanted to show an inspiring video about the history of moon landings. Except the sound wouldn’t work. Then the sound came on, but the screen went blue.
“Can we have the sound?” Winetraub asked, chuckling. “The sound is more difficult than getting to the moon. We’ll give it one more try.”
To even reach this point was an unlikely journey for SpaceIL, whose story is a quintessential Israeli startup tale. It was founded to compete in Google’s Lunar XPrize, a contest to see who could build the first private spacecraft to reach the moon. The co-founders submitted their application right at the deadline, Dec. 31, 2010, and went through a few failed experiments before building the right craft.
The first model was the size of a Coke bottle. When that didn’t work, the team made the craft the size of a dishwasher. Now they’re up to a car.
“It is rocket science,” Winetraub said, explaining the difficulty. “If it doesn’t work the first time, that’s OK, but the second time around you expect it to work, so that was hard. We did it again and the design you now see on the launchpad is the third or fourth iteration.”
The XPrize shut down without a winner last year, but along the way SpaceIL received enough funding to keep going. It’s working in partnership with Israel Aerospace Industries, and its donors include the U.S. billionaire casino mogul Sheldon Adelson, South African-Israeli billionaire Morris Kahn and Canadian-Israeli real estate mogul Sylvan Adams.
The mission has also become a kind of cause celebre. Buzz Aldrin, who knows something about getting to the moon, tweeted his best wishes Wednesday. His Apollo 11 mission landed on the lunar surface nearly 50 years ago.
“If the #SpaceIL mission is successful this Thursday, Israel will become the fourth country to land an aircraft on the moon,” he wrote. “Good luck, Beresheet!”
The spacecraft will raise an Israeli flag once it reaches the moon. It will carry a time capsule with the entire Bible printed in microscopic text on a coin, along with hundreds of other documents compressed onto small discs: dictionaries, encyclopedias, and Jewish and Israeli texts like the Israeli national anthem and the traditional Jewish prayer for travelers.
The mission also will include scientific research. In partnership with NASA and The Weizmann Institute, an Israeli university, the craft will test the moon’s magnetic field in addition to taking photos and video. After two days the craft will be shut off and the mission will be complete.
But SpaceIL doesn’t think its work will end there. The organization also hopes to inspire Israeli kids to go into science and engineering by showing them that space exploration is achievable. Its educational programs have already reached a million children, whom SpaceIL engages by asking them to help solve certain problems the craft might face, like how to stabilize with fuel sloshing around inside. The craft’s time capsule also will include drawings from Israeli kids.
And SpaceIL is hoping to engage the Israeli public in the mission. There is even a Spotify playlist of Israeli songs appropriate for the launch featuring “Space Shuttles” by the Israeli singer Berry Sakharof.
“It’s the first Israeli spacecraft, but hopefully not the last,” Damari, another co-founder, said at the news conference.
When kids ask him if the craft will return, he says, “We tell them no, it stays there with the time capsule and all sorts of interesting things inside. It’s your job to reach the moon and bring it back.”
