CAPE CANAVERAL, 22 Feb 2019:
A SpaceX Falcon 9 rocket blasted off from Florida last night, carrying Israel’s first lunar lander on a mission that – if successful – will make the Jewish state only the fourth nation to achieve a controlled touchdown on the moon’s surface.
The unmanned robotic lander dubbed Beresheet – Hebrew for the biblical phrase “in the beginning” – soared into space from the Cape Canaveral Air Force Station at about 8:45pm EST (0145 GMT Friday) atop the 23-storey-tall rocket.
Beresheet, about the size of a dish-washing machine, was one of three sets of cargo carried aloft by the Falcon 9 – part of the private rocket fleet of billionaire entrepreneur Elon Musk’s California-based company SpaceX.
The rocket’s two other payloads were a telecommunications satellite for Indonesia and an experimental satellite for the US Air Force.
Beresheet was jettisoned into Earth orbit about 34 minutes after launch, followed 15 minutes later by the release of the two satellites, according to a SpaceX webcast of the event.
In addition to a textbook launch and payload deployments, SpaceX scored yet another success in its pioneering technology for recycling its own rockets.
Just minutes after blastoff, the Falcon 9’s nine-engine suborbital main-stage booster separated from the upper stage, flew back to Earth and landed safely on a drone ship floating in the Atlantic Ocean more than 300 miles (483km) off the Florida coast.
As seen from the launch site, the distant glow of the returning booster rocket was visible in the sky just as the moon appeared over the horizon. The spectacle drew cheers from mission control engineers.
The encouraging moment came on the eve of a key hurdle for SpaceX to clear in the company’s quest to help NASA revive its human spaceflight programme.
NASA is expected to later today decide whether to give its final go-ahead to SpaceX for a first, unmanned test flight on March 2 of a new capsule the company designed for carrying astronauts to and from the International Space Station.
Beresheet is slated to reach its destination on the near-side of the moon in mid-April following a two-month journey through 4 million miles (6.5 million km) of space.
A flight path directly from Earth to the moon would cover roughly 240,000 miles (386,242km), but Beresheet will follow a more circuitous route.
If all goes according to plan, the spacecraft’s gradually widening Earth orbit will eventually bring the probe within the moon’s gravitational pull, setting the stage for a series of additional manoeuvrers leading to an automated touchdown.
So far, only three other nations have carried out controlled “soft” landings on the moon – the US, the former Soviet Union and China.
Spacecraft from several countries, including India’s Moon Impact Probe, Japan’s SELENE orbiter and a European Space Agency orbital probe called SMART 1, have intentionally crashed on the lunar surface.
The US Apollo programme tallied six manned missions to the moon – the only ones yet achieved – between 1969 and 1972, with about a dozen more robotic landings combined by the Americans and Soviets. China made history in January with its Chang’e 4, the first to touch down on the dark side of the moon.
Beresheet would mark the first non-government lunar landing. The 1,290-pound (585kg) spacecraft was built by Israeli nonprofit space venture SpaceIL and state-owned defense contractor Israel Aerospace Industries with US$100 million furnished almost entirely by private donors.
Beresheet is designed to spend just two to three days using on-board instruments to photograph its landing site and measure the moon’s magnetic field. Data will be relayed via the US space agency NASA’s Deep Space Network to SpaceIL’s Israel-based ground station Yehud.
At the end of its brief mission, mission controllers plan to simply shut down the spacecraft, according to SpaceIL officials, leaving Beresheet as the latest piece of human hardware to litter the lunar landscape.
Separately, a Japanese space probe named after a falcon, Hayabusa 2, has touched down on an asteroid more than 300 million km (186 million miles) from Earth on a mission to seek clues about the origins of life, Japan’s space agency said today.
The spacecraft’s landing on the asteroid Ryugu, just 900m in diameter, came after an initial attempt in October was delayed because it was difficult to pick a landing spot on the asteroid’s rocky surface.
The Japan Aerospace Exploration Agency, or JAXA, said Hayabusa 2 fired a small projectile into the surface of Ryugu to collect particles scientists hope the spacecraft will bring back to Earth for analysis.
“We may have caused some worry due to the delay but we carried out our plan flawlessly over the past four months to bring it to a successful landing,” project manager Yuichi Tsuda told a news conference. “It landed in the best circumstances among the scenarios we envisioned.”
It is the second Japanese spacecraft to land on an asteroid after Hayabusa touched down on a near-Earth asteroid named Itokawa in 2005. It was the first to bring asteroid dust back to Earth, although not as much as hoped.
Asteroids are believed to have formed at the dawn of the solar system and scientists say Ryugu may contain organic matter that may have contributed to life on Earth.
JAXA’s plan is for Hayabusa 2 to lift off Ryugu and touch back down up to three times. It blasted off in December 2014 and is scheduled to return to Earth at the end of 2020.
