Chinese Lunar Probe Lands Successfully

China's Chang'e 3 moon probe made its intended landing earlier today, setting down softly in the moon's Sinus Iridum, as reported by Reuters. From the article: "The Chang'e 3, a probe named after a lunar goddess in traditional Chinese mythology, is carrying the solar-powered Yutu, or Jade Rabbit buggy, which will dig and conduct geological surveys. ... China Central Television (CCTV) broadcast images of the probe's location on Saturday and a computer generated image of the probe on the surface of the moon on its website. The probe and the rover are expected to photograph each other tomorrow. ... The Bay of Rainbows was selected because it has yet to be studied, has ample sunlight and is convenient for remote communications with Earth, Xinhua said. The rover will be remotely controlled by Chinese control centers with support from a network of tracking and transmission stations around the world operated by the European Space Agency (ESA)."

    In case anyone cares, the first soft moon landing was on January 31, 1966 by the Soviet lander Lana-9. It still boggles my mind how they were able to achieve that without anything remotely resembling a modern computing device.

      Nitpick: the name is Luna-9.

      The first landing of any kind (a crash landing), was the Soviet Luna-2 in 1959. The U.S. then sent a series of crash-impact spacecraft in the early 1960s, the Ranger series, whose goal was to take photos during the final descent, along with testing out systems. Five of the nine Ranger missions successfully impacted the moon, and three of them managed to send back photos.

      Then as you note, Luna-9 was the first non-crash landing, in 1966.

      Curiously, in my youth in the 60's, we referred to Luna-9 as a "hard landing", and the first "soft landing" was Surveyor 1 three months later. Now, it's clear that the Luna 9 lander really was a soft landing (similar to the landings of the Mars Pathfinder and Spirit/Opportunity rovers) and we were just ragging on the Soviets.

      As an interesting addendum:

      Luna-9's pictures were sent back using one of the standard encodings used for wireless newspaper photography transmission. During the transmission, the Jodrell Bank radio telescope in the United Kingdom was listening in (well, wouldn't you?) and the astronomers there recognised the encoding, phoned someone at the Daily Express, and as a result the first pictures from the surface of the moon ever were printed in a British newspaper while the USSR was still wondering what to do with them.

      There is some speculation that the encoding scheme was picked deliberately to make sure this happened...

      Luna 9 did not have a computer. It was all careful launch timing and Newtonian mechanics to ensure it got where it needed to be and deployed what it needed to precisely when it needed to. The closest thing it had to a computer was a clock that made these things happen at precise intervals. From Wikipedia:

      The lander had a mass of 99 kilograms (220 lb). It used a landing bag to survive the impact speed of 22 kilometres per hour (14 mph).[2] It was a hermetically sealed container with radio equipment, a program timing device, heat control systems, scientific apparatus, power sources, and a television system.

      If the whole thing weighed 220 lbs., where would you even fit a meaningful 1966 computer? Never underestimate persistent human beings.

    There is a cool animated gif of the descent imager pictures of the landing, and a false color image of the surface.

    China has no debt? Really? China is no paragon of fiscal virtue, they're barreling down the road to financial ruin unless they do some significant restructuring.

    What about money? We have resources lying around the country already - both human and material. We have the ability to do it all over again, any time.

    What we lack, is backbone, initiative, the dream, the drive, the balls. Our leaders today are less than men, and there seem to be no real men to run the worthless bastards out of power.

    Money. Money is important, in it's own right, but money doesn't control our ability to aim high. That ability is only governed by our lack of courage.

    Not even the English can claim a continent, right?

    Anyone can claim any damned thing they like. If they are the only people around, they get to set the rules. If China puts a crew up there, with orders to confiscate the US flags already there, and replace them with Chinese flags, WTF are we going to do about it? Run to the United Nations, to whine and snivel?

    For guys my age (I turned 50 last week), the first Moon walk was a pivotal event. July of 1969... I was 6 years old, and my father was a squadron commander in the 318th Fighter Squadron flying F-102s, and I lived on Cherry Hill on the Air Force base in Anchorage Alaska. We all watched the first steps taken on the Moon, and as the son of an Air Force fighter pilot, there were high expectations for me. I remember when pilots where heros. Everyone expected even greater things from my generation.

    We totally let them down, at least in terms of space exploration. I blame politics, and to some extent NASA (though mostly because of politics). I also have my hopes pinned on commercial efforts like SpaceX. We were on the Moon in 1969, while people in China were still starving. I'm glad China has revived some of the dream, and I hope they do well. In the meantime, our generation gave birth to personal computers and cell phones, so it's not a total loss, but there never was another OMG moment like the Moon walk.

    Your leaders, sir, have been put there by voters.

    No, they've been put there by the people who get to choose who's on the ballot, mostly by throwing tons of money to ensure one of their kind of people wins. You can hardly blame the voters when they're given a choice between Tweedledum and Tweedledumber.
