Some bittersweet news today as we get word that Israel’s Beresheet spacecraft unfortunately crashed shortly before touchdown on the Moon. According to telemetry received from the spacecraft right up until the final moments, the main engine failed to start during a critical braking burn which would have slowed the craft to the intended landing velocity. Despite attempts to restart the engine before impact with the surface, the craft hit the Moon too hard and is presumably destroyed. It’s likely that high resolution images from the Lunar Reconnaissance Orbiter will eventually be able to give us a better idea of the craft’s condition on the surface, but at this point the mission is now officially concluded.
It’s easy to see this as a failure. Originally conceived as an entry into the Google Lunar X Prize, the intended goal for the $100 million mission was to become the first privately funded spacecraft to not only touch down on the lunar surface, but navigate laterally through a series of powered “hops”. While the mission certainly fell short of those lofty goals, it’s important to remember that Beresheet did land on the Moon.
It didn’t make the intended soft landing, a feat accomplished thus far only by the United States, Russia, and China; but the fact of the matter is that a spacecraft from Israel is now resting on the lunar surface. Even though Beresheet didn’t survive the attempt, history must recognize Israel as the fourth country to put a lander on the surface of our nearest celestial neighbor.
It’s also very likely this won’t be the last time Israel reaches for the Moon. During the live broadcast of the mission, after it was clear Beresheet had been lost, Prime Minister Benjamin Netanyahu vowed his country would try again within the next two years. The lessons learned today will undoubtedly help refine their next mission, and with no competition from other nations in the foreseeable future, there’s still an excellent chance Israel will be able to secure their place in history as the fourth country to make a successful soft landing.
Of course you’ve got to get to the Moon before you can land on it, and in this respect, Beresheet was an unmitigated success. We previously covered the complex maneuvers required to put the craft into lunar orbit after riding to space as a secondary payload on the Falcon 9 rocket; a technique which we’ll likely see more of thanks to the NASA’s recent commitment to return to the Moon. Even if Beresheet never attempted to land on the surface, the fact that it was able to enter into a stable lunar orbit and deliver dramatic up-close images of the Moon’s surface will be a well deserved point of pride for Israel.
If there’s one thing to take away from the loss of Beresheet, it’s that travel among the stars is exceptionally difficult. Today we’re reminded that even the slightest miscalculation can quickly escalate into tragedy when we leave the relative safety of Earth’s atmosphere. In an era when a mega-rocket launching a sport’s car live on YouTube seems oddly common place, it can be easy to forget that humanity’s long path to space featured as many heartbreaking defeats as it does triumphant successes.
This won’t be the last time that hundreds of millions of dollars worth of high-tech equipment will be lost while pushing the absolute edge of the envelope, and that’s nothing to be upset over. Humans have an insatiable need to see what’s over the horizon and that means we must take on a certain level of risk. The alternative is stagnation, and in the long run that will cost us a lot more than a few crashed probes.
