Hayabusa Probe Lands on Asteroid After All
pin_gween writes "Reuters.UK is reporting the the Hayabusa space probe successfully landed on the asteroid Itokawa. JAXA officials are trying to determine whether to attempt another landing. The probe has had a series of glitches, and failed to drop a set of instruments upon landing."
Considering that they lost connection with it and how it still managed to land perhaps they should rename it the Zatoichi probe.

...apparently did not deploy its sampling tools, which was kind of the point of the mission. Still, it's a pretty major feat and the article says they might try again, to see if they can get their samples. And check out this great image of the asteroid with the probe's shadow.

Look, a TIE-fighter shadow! (which as everyone knows, is a short-range fighter.)
One line blog. I hear that they're called Twitters now.
Make sure it has the fire wheel equipped for Jacquio. And kill the tail first when you fight the statue.
Anyways....why did they send the probe up anyways
For the same reason we send robots into hazardous environments - it is too dangerous to justify sending humans.
We need to know how to land on asteroids. That skill might become valuable someday.

Just do what NASA does and ram that asteroid kamikaze style.
Ooo man the floppy drive is broken. No wait. The computer is just upside down.
You have to wonder just how autonomous this probe is, if the news that it successfully landed (and has subsequently taken off again) comes as a surprise to Mission Control.
With the number of setbacks the probe has had,I was honestly surprised to hear they made a relatively successful landing (minus the tool deployment). Considering the number of people out there claiming the first lunar landing never happened, I'm also surprised that there aren't more skeptics out there demanding more proof that the probe did land on the asteroid and that this isn't doctored data to help the Japanese space agency save face. I mean, hitting a fast moving target with a glitchy probe is an amazing feat. I guess this isn't a major space agency and this isn't a major project compared to NASA and the first manned lunar landing, so it's not going to attract the attention of the fringe...
It can be done in one, move the far A value in JAXA to the front to spell AJAX
If you don't vote, you don't matter, so don't waste your time telling me your opinion
(disclaimer: I know absolutely nothing about this topic)
Does anybody know whether we could use asteroids to transport probes around space?
Wouldn't an asteroid potential provide a fast and free transportation system? Wouldn't they provide rudmentary protection against space radaition somewhat?
If you ask me, NASA and other space agencies should be firing out probes like crazy. Small, inexpensive ones. Do lots of them. And make it so they can communicate with each other. Sort of like a mesh network in space: so one far away could communicate back via other ones.
We seem to spend a lot of time and money fussing about with silly low gravity science on ISS when we could be exploring the galaxy with probes. I've been very impressed with the Mars probes and would like to see more of that sort of thing.
We could just ask Bruce Willis.
I don't think we have to ask. I think he bolts himself in a rocket every night before he goes to sleeep.
"Rocky Rococo, at your cervix!"
I guess third time is not a charm, pretty good college try for their fledgeling space agency. I hope they do better on their ramp up to build a base on the moon by 2025. These kinds of problems on a mission like that could spell disaster. I wonder if anyone over there is thinking, "Maybe we should just stick with robots."
... what did you expect, something profound?
Of course it's dangerous! It's space! Vacuum, radiation, and all that. And yes, unmanned probes do a wonderful job scouting things out (look at the Voyager probes and the Mars rovers). But unless we're planning to colonize Mars with von Neumann robots and allow them to become an advanced civilization bent on destroying humanity (cue Battlestar Galactica theme [the old one]), Mankind is eventually going out there to face the hazards.
This is the same argument they made when the idea of going to the Moon came up. Jerome Wiesner, head of the Presidential Science Advisory Committee recomended to Kennedy that unmanned Moon probes would be more cost effective and just as useful in beating the Russians. But the Russian had been besting us in human spaceflight, not probes (it seems like every probe they tried to send to Mars crashed or missed the planet) and in the end, men went to the Moon, though the Surveyor and Ranger probes went there first to scope things out.
What it comes down to is that there are alway Nervous Nellies who look at the expense and/or danger factor involved in something and go "we shouldn't do that" while simultaneously hiding under their beds. The movement of Mankind to space is inevitable, just as Columbus, Magellan, Cook, the Wright Brothers, and Lindbergh leading us into new frontiers was in their time. You can't stop progress, and anyone who thinks we're going to sit here on our over-crowded, polution-tinged rock and let the robots have all the fun is kidding themselves.
Besides, I want a job as an asteroid rockhound.

Robotic probes just run off a power supply. Now consider which is cheaper to launch.The World Wide Web is dying. Soon, we shall have only the Internet.
Over a distance of 3x10^11 m they land on an object only 548 m long. The corresponding opening angle is so small that my calculator cannot do the math.
Congratulations!
Storyline:
....
On Nov. 9, the Hayabusa moved within 70 meters of the Itokawa during a descending test that aimed to verify the guidance and navigation functions.
The cause of an anomaly that led to the cancellation of the rehearsal scheduled on Nov. 4 was clarified, thus we will carry out its landing at the "MUSES Sea" and sampling under the following schedule.
Captain: What happen ?
Mechanic: Somebody set up us the bomb.
Operator: We get signal.
Captain: What !
Operator: Main screen turn on.
Captain: It's you !!
CATS: How are you gentlemen !!
CATS: All your base are belong to us.
CATS: You are on the way to destruction.
Captain: What you say !!
CATS: You have no chance to survive make your time.
CATS: Ha Ha Ha Ha
Hayabusa Mission Control: Transmission ended...
$sys$Hayabusa
The first successful asteroid landing attempt was done on Eros by the NEAR spacecraft :
See Here.
The amazing thing is that NEAR was not even designed to land : they mission controllers did it because NEAR was running out of fuel and would be turned off anyway so they decided to chance it. They put it down (after a few bounces on the surface too) and turned it off. One day they might try to turn it on again.
The point is, that it is not impossible to do it. Indeed, the physics is pretty simple. There is no "hitting a fast moving target" problem : the probe is already in orbit and moving pretty slowly relative to the asteroid. The problem is systems engineering : all the problems that you see from the probe is not because some tools malfunctioned outright etc, it is poor integration of systems. Just look at the communications downlink blackout during the landing rehearsal that results in the loss of the MINERVA miniprobe. I mean, come on, you can PREDICT when those blackouts occur!
Finally, your rant about "Japanese cheating to save face" is just pure flamebait.

I wonder what CD-ROM they were listening to when they lost connection to the space probe?
Sony strikes again.....

Hmmm. It's going to have to hussle its metallic behind to make that deadline.
The last part just reminds me of the Monks' song "Skylab": ... something came down on me head. Look at the size of that. It looks like a bloody big tin can.

If I have in fact read more into it, I apologize, but these are things I feel passionate about. As a matter of fact, the greatest saying to come from the Apollo program was "If we can put a man on the Moon, why can't we... [put your favorite problem here]." And truth be told, there is no reason we can't cure cancer or AIDS, house the homeless, feed the hungry. And believe it or not, we can do these things. It requires the same level of dedication that the men and women of NASA brought to Apollo, along with putting aside profitability and nationalistic pride.
I feel mankind has to explore space, because ultimately there are resources we can tap there to improve life here. Imagine being able to ship heavy industrial manufacturing up to the Moon, reducing the amount of pollution and environmental damage. The Moon is just chock full of mineral resources waiting to be tapped, so we no longer have to lay waste to our planet to dig them out. The list goes on.
I want us to start thinking about this seriously now, before we're forced to in the future by some cataclysmic event. If it's an agenda, then I think it's an important one. As always, opinions will differ.

Hayabusa has dropped that plaque bearing the names of Steven Spielberg and Arthur C. Clarke, and if not, might there still a chance on the next approach?!?
It takes a signal from earth almost 17 minutes to reach the spacecraft. It takes the same time to get feedback. Also think about the spacecraft's and asteroid's speed. Just try to steer your car with a delay of half an hour. Now you have the right feeling, eh? I think ESA, JAXA, NASA, etc. are doing an amazing job.
If we want to continue growing, sooner or later we're going to *have* to move a lot of our industry off Earth. Your economic thoughts, I think, are based off of the startup efforts. Sure, it'd be expensive as hell, and take literally decades to start showing a profit, but once it did, it would have broken us out of our finite resources here on Earth.
That's the kind of goal, if you want to achieve it, you start planning as soon as you realize it will one day be necessary. Planning, building, *doing*.
