I was just watching it live, cheering for SpaceIL, it's a pity that the landing was not successful.
I was part of the engineering team of the Japanese team Hakuto of the Google Lunar XPRIZE. I always wondered how it would feel to be in the control room at this time, but our launch deal fell through. I can understand what the SpaceIL engineers are going through right now.
Congratulations to all the SpaceIL team for reaching this far, your work has been impressive. Keep trying and you will make it!
Contrast with Elon Musk saying the next launch of the Falcon Heavy (today) has a 5-10% chance of failure. [1] This is after it has already successfully launched once.
I'm sure/I'd hope the actual engineers on the project wouldn't align to that tweet's wording by the marketing team (aka, they prob wouldn't be that cocky/have phrased it that way themselves).
This comment thread is both celebratory and hateful, truly disgusting from Hn.
Celebrating space mission failures for any reason is a terrible look.
This is a cultural difference, try to take a step back from your own preconceived cultural norms. What's considered confidence in Israel would qualify as hubris in American culture - there's much less value placed on being humble or soft-spoken in Israeli culture. I make no judgements about if this is better/worse but I certainly wouldn't dream of relishing in their failure even if I perceived them as "cocky".
I'll play the contrarian and suggest that a space race is the best kind of national pride. If you're okay with football (soccer) or Olympics pride, this is, in my mind, better still.
And ironaically, as you suggest, when one country wins, we in fact all win.
I would much rather we fight to push back the boundaries of space than to hurl actual bombs at each other.
This! While my sentiment may feel a bit Star Trekky/naive, our quest to get to the stars will only succeed if we, as a planet, pull together. If we dont, we'll be limited to this solar system. China, US, India, Israel, Russia (sorry for anyone else Im missing :-)), are all pioneers and we should celebrate their successes, and continued desire to push the envelope.
It’s time to retire the ignorant notion that nation-state space programs can be morally disentangled from the governments pursuing them in no small part for political ends. Their success is the regime’s success.
Indeed, and the Israeli project was a new experiment in low cost, volunteer rich space exploration. Its outcome and repetition _is_ significant to everyone. Indeed, nationalistic associations distract from rather than enhance a project.
And we have a few examples of internationalism already like the ISS. And presumably any Mars mission will have to be international. Which is another one of the reasons such projects is worth while.
Agree to disagree here. The whole "we're all one people thing" is a great idea and all (I'm a huge fan, would love for the U.N. to be something other than the personification of national relations and instead be a real governing body) but that's not how things work.
This is Israel's project. They had assistance from other organizations/countries, but they're not doing this to better North Korea in any real way and you shouldn't hold North Korean responsible for their failure.
> On the way down, the main engine cut out. The engine was successfully restarted, but then communications were cut off, and no more information was sent back.
Definitely a terrible time to have an engine failure :/
Based on the telemetry from the broadcast it seems that there was a failure at 13km that resulted in both telemetry and engine loss. When telemetry connection came back vertical speed has already doubled and it kept going up until spacecraft hit the ground. Engine was probably never restarted.
Edit1:
Telemetry came back at 10k. For the next minute and a half there was uncertainty about the main engine even though telemetry clearly showed vertical speed going up fast. More then a minute later, at 5k a reset request was made.
Edit2: A minute goes by and at about 500m controller asked if there is a confirmation to send rest to JPL, another, announced that engine is on. Crash happens at that moment. 149m, 134.3ms vertical.
When they said the engine had a problem the altitude was 678m and vertical velocity was 130.1m/s. After restart it was 149m at 134.3m/s. They never had a chance. Assuming those numbers were correct. A few minutes before they had lost the intertial measurement unit.
then communications were cut off, and no more information was sent back.
Have any of these moon landings been done at night where people have been able to watch it happening through a telescope? Or are things so small at the moon's distance that there'd be nothing to see?
There was mention there about IMU issues - losing track of where you're pointing, then trying to recover could mean you're pointing the wrong way (while still running the main engine ....)
Surprised by the sheer number of naysayers on the thread. What is wrong with you people?
7th country to get that far in space, 4th to attempt to land, those are enormous achievements for a country that's has 2/3rds the population of New York (city, not state) and doesn't have a hundred billion dollars to burn in a dick-measuring contest. They'll launch another one and land next time.
Article subtitle: "The failure of the landing highlighted the risks of a fast and cheap approach to space exploration."
I would say the opposite. Not specifically just in reference to this mission but in general. They now have a lot of experience and data to use going forward for "not much" expense. A lot of extremely expensive missions were lost because they didn't have the opportunity to iterate.
The history of rocketry really took off during WW-II, and was further refined by the military (generic, but pretty much the nations that have successfully landed on the moon), further developing and releasing to civilian government, and eventually private interests.
If I were to make a guess extrapolation to air-flight we're probably still roughly in the 1940s. Private space flight is making things more standard and long-run production instead of one-offs; but we aren't there yet and haven't found workhorse designs that are both reliable and cheap. Experiments like this will hopefully help us get there.
If at first, you fail, try and try again. This was sobering. I watched expecting the normal rush I get when watching live events of this nature but it was not to be.
Landings and take offs are always the hardest part of any aerospace event. You're much more likely to see system or mechanical failures when you first start everything up or try to stop moving on an uneven surface.
It seems Israel is doing just fine economically and technologically. So I don't get why US politicians still justify giving out O($billion) every year in foreign aid while there are ample opportunities to spend them in their own country.
Because if you just gave billions of dollars to Lockheed-Martin, Boeing, and Raytheon people would complain. So you give it to someone and make them buy from these guys.
I am not sure what connection that Buzz Aldrin had to the folks at SpaceIL but thought he had a pretty classy tweet tonight. Guess everyone in the space community pulls for each other.
I haven't been able to find what it would have done had it landed correctly.
(edit)
I guess it had a few scientific instruments and a "time-capsule" of sorts. Wikipedia editors are fast, they already have the crash on there.
The spacecraft carried a "time capsule" created by the Arch Mission Foundation, containing over 30 million pages of analog and digital data, including a full copy of the English-language Wikipedia, the Wearable Rosetta disc, the PanLex database, a Nano Bible (complete Bible in Hebrew), children's drawings, a children's book inspired by the space launch, memoirs of a Holocaust survivor, Israel's national anthem (Hatikvah), the Israeli flag, and a copy of the Israeli Declaration of Independence.[8][35][36][37][38]
Its scientific payload included a magnetometer supplied by the Israeli Weizmann Institute of Science to measure the local magnetic field, and a laser retroreflector array supplied by NASA's Goddard Space Flight Center to enable precise measurements of the Earth–Moon distance.[39][40]
---------------------
As an aside, the youtube video series on the original Apollo launch computer it pretty neat. (The core memory on those old machines was nuts..)
I don't understand how you even attempt to recover from failures that occur during a descent like this. Latency to the moon appears to be 1.3 seconds. How much time do you have to do anything?
Far from it. Both the USA and USSR have crashed multiple landers before successfully touching one down. And that doesn't even count intentional "impactor" missions that came before that.
This project wasn't started by the state or by any university. This was a, mostly, volunteer project that wanted to excite children about STEM and space and to educate the young generation. The Prime Minister was invited because it was cool, but it was a private endeavour.
So now you want to convince me that in 1969 they could man land on the moon and then come back to earth and in 2019 they still trying to nail down the tech ?
Do I detect a bit of condescension in NYT's tone? Do we need to remind the numerous failures US & USSR had before they got their space program off the ground? Also, they forgot India who did send a lunar orbiter and sent a probe on Moon's surface back in 2008.
