For Americans:

Time Zones:
EST is UTC/GMT minus 5 hours.
CST is UTC/GMT minus 6 hours.
MST is UTC/GMT minus 7 hours.
PST is UTC/GMT minus 8 hours.


Which means:

4:03 AM EST / 1:03 AM PST - Lander separation
11:03 AM EST / 8:03 AM PST - Expected landing
12:00 Noon EST / 9:00 AM PST - Earliest possible images

(According to the Planetary Society timeline linked by catblack.)

A true Carl Sagan moment should the landing be nominal. Don't get to use nominal much.

Their site countdown gives about 29 minutes to separation.

Somehow I think I may not stay up for this one. Also, as I have no lucky JPL peanuts and this is an ESA joint, what's the good luck food? Toblerone? Wine? Wine-flavored Toblerone?

Just read that there was a failure to activate one of the gas thrusters that would dampen a bounce if the lander comes in too fast. But they decided to go for it anyway and rely on the ice screws and harpoon. Yes, harpoon.

At lunch with co-workers yesterday I was stunned at the ignorance. It would have been better if they were completely unaware, but worse, they were sort of aware.

"How do they catch up with it?"
"Won't it burn from the fire trail behind the comet?"
"I heard there's some top-secret military stuff on it."

These are grown-ups with college degrees working in a world-class IT department.

I understand not everyone is into space stuff, and I'm certainly ignorant about a lot of subjects, but some of their questions were third-grade level stuff or just total wackjob statements.

that's the problem with astro-nationalism (or Cosmo-nationalism). If this were a NASA mission there'd be more publicity in the US.

also, this is extremely great. in terms of increasingly knowledge this is probably more important than the Mars missions. you'd think Houston would be in on this given the great hopes of finding hydrocarbons on this icy rock.

Bleeding news from the livestream scientists/smartypants:

Telemetry from lander and probe are both good. Lander seems to be aligned properly from first photos and is currently rotating, which takes about 9 mins to complete the maneuver.

Less than 1 hour out, but with a decent window for actual vs proposed landing time.

There is a specific landing camera on board, ROLIS (Rosetta Lander Imaging System). The lander is using the Rosetta Spacecraft to transmit data to Earth (the entire lander masses 100kg, only 2.4kg is comm gear, including the antennas.)

I suspect the images are being sent live to Rosetta but stored there, what ESA wants right now is lander and spacecraft telemetry.

About 1 meter per second, 2.2 mph. There's not much gravity. This isn't landing on the Moon by any stretch, this is drift by and grab.

Interesting. I didn't realize Philae was so small. Only about 1 cubic meter.
posted by Thorzdad at 7:05 AM on November 12, 2014


Thorzdad, slowing down isn't the problem, bouncing off is. There is only 1/10,000 g. The thruster is to hold the lander down while the screws and harpoons do their work.
posted by indyz at 7:07 AM on November 12, 2014


How fast is it traveling?

She (the livestream host) gave an altitude distance in km a few moments ago. I don't recall the value but that divided by 45 mins could give a [very, very] rough idea of speed.

About 1 meter per second, 2.2 mph.

Per eriko's numbers this means, given a 45 min time to touchdown, a height of 2.7 km. Exciting.

All this Europe and ESA grandstanding is a bit annoying though. It's annoying when any country does it.

While I understand why they're doing it, I was hoping that they would make this all about the science and only about the science, and if you're going to give accolades, give it to the individual men and women who made this happen.

What grandstanding ?

I heard it in the livestream, but only from one speaker. He just made it clear, overly much perhaps depending on your point of view, that this was all about the European this, that, and the other. All thanks to Europe. It was slightly jarring I suppose, but doesn't seem to be the theme otherwise that I've seen.

There's a lot of post processing needed. They shoved out that very badly blown out shot of the lander, it was there to confirm the landing legs deployed, but I suspect that most of the mission team is just watching the telemetry and sweating a lot, and once they get current dark slides and such, they'll process and release the photos.

Spacecraft cameras tend to be run full bore, they're full of noise and artifacts that has to be compensated for. They do this for the extra sensitivity they can get out of them when you run them at the limits. Our digital camera uses sensors that run well away from that threshold, which gives much smoother pictures.

If Philae isn't able to secure itself to the comet's surface, what with its cold thruster possibly not working, I have sad images of it bouncing off and sending a series of desperate final photos as it drifts inexorably away like a doomed astronaut in a bad sci-fi movie.

Space is HARD.

Which is why I find myself in awe as I sit in front of my computer this morning, with a live stream open in one tab, this thread open in another, discussing the fact that a small human made device is - right now - attempting to land on a comet. And I can follow, discuss, and interact with people around the world in real time about that event. The technology that goes into making this moment possible - Rosetta, Philae, the internet, the millions of computers and mobile devices people are following this from - is really something.

It's one of those moments that remind me that I am living in the future, that whatever all our collective failings are, humanity is also capable of moments of amazing achievement and audacity.

This is the best final resting place Philae could have. When you consider that the other options were "trapped and mute until the power runs out" or "tumbling forever through the vacuum of space with its instruments trying to work and failing" I think this is the happiest of endings. After 11 years, Philae is home.

The Rosetta mission is planned to run until December 2015, but if enough fuel remains in the spacecraft’s tanks, mission controllers may extend its life by six months and give the mother ship more high-risk tasks, such as flying through one of the gas and dust jets streaming from the comet. Philae has initial battery power to last 40 hours but will then switch to rechargeable ones replenished by sunlight.

The lander could continue working until March next year, when the electronics will become too warm to work properly. Even when Philae packs up, it may still cling on to the comet, perhaps for several 6.45-year-long laps around the sun, before enough material erodes from the comet’s surface for the lander to lose its grip.

Anyone know what this means?

First graph is temps on five sensors, though two of them are reporting off-scale low, and I suspect that CIVA, which is the infrared camera, is (probably) off-scale high. It's probable that what we're really seeing there is that those systems haven't been turned on yet, though I suspect the battery is a failed sensor. The plan is to run first on one battery alone, then recharge a second battery and run on that.

The bottom graph is electrical current at various places. I suspect the first two are bus current, the next two are solar panel current, and the last three are battery charge/discharge.The plan is to run first on one battery alone, then recharge a second battery and run on that. This goes well with the last three lines "PSSH (power sub system ????)_C(current)_SBat/PBbat(secondary/primary battery) and then CH(Charge) and DCH (Discharge).

Sure enough, we're seeing a discharge rate of about 1.5A currently on the primary battery, and .5A on the secondary battery. We're seeing almost no charging on the secondary. The HPC_IN and LPC_IN are showing some current, totaling about .8A, I'm assuming this would charge the secondary battery but right now is probably being shunted into a heater.

ESS is the electrical support system, the power controller, MSS was responsible for firing the harpoons and screwing in the legs, it's now monitoring internal body temp of the probe.

posted by T.D. Strange at 8:46 AM on November 12, 2014


Hmm.

Harpoons didn't fire after all, and they're not confident the thrusters fired. They're now really worried that they might have bounced, and they're considering trying to refire the harpoons. Escape velocity here is on the order of 1.1m/s, so a bounce is very possible, and if they retained half the velocity, it's going to come right back off.

Newest tweet states a very gentle touchdown, based on landing gear damping amount. If they landed slower than escape, it'll stay.

The most amazing thing to me is that we did this with pre-2004 technology. The iPad hadn't been invented (or at least released) yet, and smart phones were still kind of curiosity. It was a literally a different world for consumer technology back then, and given the lead time on a project like this I'm guessing there is very little tech on the comet from this century. I don't know how the pace of change in consumer tech relates in space exploration, but still. They did this with mostly "old" technology by todays standards.

If Philae isn't firmly anchored but is stable on the surface, most of the science can still happen, but two experiments, MUPUS and SD2, will be in danger. MUPUS (MUlti-PUrpose Sensors for Surface and Sub-Surface Science) require shoving a probe into the surface, and SD2 (Drill, Sample, and Distribution) requires drilling. If the lander isn't firmly anchored, they can't risk activating those, there's more than enough force to push the lander off the comet.

Honestly, if it landed and stays landed without being attached to the comet, that's actually more impressive than if it had been anchored. The landing velocity was juuuuuuuuuust right (hopefully!)

Yes, if the harpoons fire and don't hold, there would be more than enough force to push them back off. If the thruster was working, they could fire that to hold them down, then try the harpoons, but the fuel tank valve failed and won't open.

If they fire and grab, Philae would be pushed off the comet, but then could be reeled back in.

My gut feeling (on very limited data) is that if they feel that they're not dealing with more than 1.1m/s velocity, they know they'll stay there. They'll run all the other science, then look at how to save the MUPUS/SD2 experiments -- possibly by firing the harpoons and hoping they can reel back in.

But this really depends on how stable the lander is. The lander gear compression (4cm) was such that they're pretty sure they're on a soft surface. It may be that that harpoons won't be able to grab anything.

If the ice screws are actually in the soil, that bodes well. Those are the primary anchors. The question is did they screw into soil, or just extend into space? You can tell by looking at the current on the drive motors, it will be significantly higher if they're drilling through material than it would be if the drill is just spinning in free space.

Another factor. The comet itself is heading towards perihelion in August 2013. As it gets closer to the sun, it'll become more active, that will make holding on harder. Perihelion is a long way out, though, 1.23AU, so we're not looking at a sun grazer by any means.

No doubt. But if they're not anchored, there's no guarantee that they'll get a sample if they try to drill, the drill just might push off them off the comet. So, yeah, they'll do everything they can to get that sample, but they're going to try to maximize the total science gathered, so they'll probably wait until those experiments have taken a good amount of data before risking it.

The Orion test launch should be fun to watch because it's going up on one of these beasts.

Yep. 7000kg more to LEO (200km@28°) than the Saturn IB. One reason I'm confident in this combo is NASA knows how to make capsules, and the Delta IV Heavy is a proven booster, with six successful launches. There was an early shutdown on the first one, which was a test flight without a commercial payload.

So, I'm confident that, if they can man-rate the Delta IV H, that this will be a workable booster for LEO work, even if SLS is cancelled or runs into problems. It certainly won't get you to the Moon or Mars directly, but you could do an Earth Orbit Rendezvous mission where you make three or four launches -- one of the unfueled spacecraft, one or two of a big tank of fuel and oxidizer, and one with the crew and supplies. Dock the spaceship to the fuel tank, get on board, and go. Three DIVH launches into LEO is 84000kg, four would be 112,000kg, which is comparable to the Saturn V (118,000kg)

Of course, it's easier to build everything down here and launch it all at once, but nobody currently has a 100,000kg to LEO booster.

As far as I can tell, Philae is having Exciting Space Adventures.

Phliae is shouting "Never tell me the odds!" at Mission Control while its top thruster goes out and it skews into a spin.

Philae is jamming down the button for the harpoons and nothing is happening.
"This landing is gonna get pretty interesting," Philae says.
"Define 'interesting'," Misison Control messages back.
Philae shrugs. "Oh god oh god we're all gonna die?" if offers, deadpan.
It switches the controls to manual.
"I am a leaf on the wind," it mutters. "Watch how I soar."

"Philae, Philae, are you there? Did you make it?"
A pause.
"Philae, Philae, come in! Please answer! Philae, please listen to me, *please*, goddammit, you dragged me back from the bottomless pit, you can't leave me here *alone* now, please ..."
A longer pause.

"Space," Philae is sending back while cheers erupt in the control room. "The final frontier. These are the voyages of the starship Philae. Its ten-year mission: to explore strange new worlds, to seek out new life and new civilizations, to boldly go where no one has gone before."

Philae is doing what we dream ourselves doing.

Earth's density is 5g/m3, for Kerbin to have the 9.8m/s2 that it does, it has to have a density of almost 58.5g/m3. Given that lead has a density of 11g/m3, and Uranium is about 19g/m3, we can see why we can't ever dent Kerbin itself, no matter how much explody we put in the rocket. One does wonder how those mountains over there near KSC are standing.

It is a game, after all. You only need 4.5km/sec of ΔV to reach orbit, rather than Earth's 10km/sec.

So live feed chap said it might have bounced slightly. Then possibly the regular loss and regain of radio signal and solar power was lander rotating (I think he means rotating sideways while keeping legs pointed at ground). Something to do with the flywheel stopping on landing may have caused this rotation when the lander bounced. Then the regular loss/regain of signal settled down, perhaps meaning the lander settled again. Hence his comment "Maybe today we didn't land just once, we landed twice". But he says this is all speculation ...

An open letter:

Hey Matt,

Hi. I’m Tim. I do some science. Some is good. Today, I managed to screw up one calculation, but I compensated by writing a paragraph for a paper that I think makes a nice compelling argument for some thing that may interest a few of my colleagues. This does not amount to much, since you contributed to landing a robot on a comet. But in terms of scientific achievement, I still come up way ahead today; and so do many, many other scientists over the world.

Want to know why? How is that possible? Simple. We managed not to alienate and objectify our female colleagues today.

I know, that’s crazy, right? Want to know how? We woke up this morning, and thought, Hey, perhaps I should dress like an asshole today. Then we realized that it would be ridiculous, and that no one in their right mind would do so.

One of my absolute favorite shirts is a vintage Hawaiian shirt, dark blue, whose pattern has a fair amount of women in oh so vintage swimsuits. I'm not sure most people would look at it an think it was even semi-egregiously objectifying women. Maybe what most people think is besides the point, but I think the controversy over scantily clad women on shirts mirrors the kind of ethical dilemmas created in art vs pornography arguments.

Casting it as a discussion of women on shirts, and not as a discussion of images of scantily clad women in the workplace, on the day when the entire world is looking at your workplace, is an act of either the blithest ignorance of the effect one's actions have on other people, or the most unconvincing feigned ingenuousness I've come across in a long time.

I'll clarify what I mean by "effect one's actions have on other people". I entered school in the sciences at the tail end of the time when women were being pushed out of the field just for being women, sometimes with a bare statement like "we don't want any more women here". It seems that talk like that is going away (I hope), but there are still lots of ways people can make women feel unwelcome in the sciences. In light of the past we're trying to shake off I think we should not create environments like that. His shirt is going to be off-putting to many women - some men too, and of course some women will conversely think it's cool - but I think the vast majority will find it unpleasant, so what's the point of offending that many people?

That's a might bit harsh.

"It is magnetic field data from Philae’s ROMAP instrument that revealed the three ‘landings’. The first was almost exactly on the expected arrival time of 15:33 GMT. Philae then rebounded by hundreds of metres. In the weak gravity of the comet this bounce took about 2 hours. It touched the surface again at 17:26 GMT and bounced again before coming to rest at 17:33."

Philae has ended up 1km away from the planned landing site after bouncing and may also have damaged the solar panels.
The new location gives it only 90 minutes of sunlight every 12 hours and there is currently 50ish hours of backup battery power.

Eight out of ten instruments reporting.

Alpha Proton X-ray Spectrometer and a bit of the Multi-Purpose Sensors for Surface and Sub-Surface Science (MUPUS) are not currently running due to power requirements and because they require movement, which might destabilise Philae.

Here's a version of the panorama with Philae sketched in to show its orientation.

It's a shame the landing didn't go smoothly, it was such a beautiful approach. But now there's some exciting problem-solving going on. Already some question about whether it's possible to flex the landing gear to make the thing hop. And concern about whether it's safe to deploy the sensor modules that require mechanical actuation.

As Karen James said, "So while we were all celebrating the comet landing, Philae was in the middle of a 2hour "bounce"? Looks like xkcd has a little more work to do."

Watching the rerun of this morning's webcast. Ulamec, the head of the Philae lander team, estimates that the first "bounce" lasted for two hours, during which Philae got approx. 1 km in height and ended up 1 km away, though they're not quite sure exactly where they've ended up.

They flashed an image showing the initial landing site (red square), and where they think they ended up (blue diamond). (That's a screen cap of a web video, so pardon the quality.) Ulamec pointed out the cliff in the blue diamond area as the place they might have ended up.

> "Someone clarify for me -- can we still Do Science even if Philae is on its side? Is there significant risk to the little guy because of how it's oriented at this point?"

My understanding:

1) Yes. It's doing Science and it's still alive!

However, there are a couple of problems --

2) It's in an area that doesn't get a lot of sunlight, possibly next to a cliff wall. Since it's designed to mostly run on solar power after the first couple of days, that's problematic unless it's moved. I don't think it's clear yet whether that would be a mission-ending-earlier-than-desired problem, something that means they can't do a couple of the most energy-intensive experiments, or somewhere in between.

But Philae is designed so that it can move a little if need be, in little hops. Unfortunately --

3) It's on its side, and unsecured. That means it's not yet clear if moving Philae still even possible, and if it is, whether doing so might accidentally push Philae right off the comet by accident. There's a similar risk to running some of the experiments that involve moving parts.

So, basically, they're most likely right now trying to figure out how long Philae is likely to last as is, how high-risk it is to try moving it around or doing certain experiments, and if there is some risk, how long to wait to let other experiments run before they try it, if they try it at all.

Nonetheless, even with just the information already obtained, this was a triumph.

I'm not sure to what extent this applies during the current phase (and might be more about photos from Rosetta than from the lander), but this article suggests that the team in charge of the optics equipment has been particularly stingy with releasing photos, as is apparently their prerogative as the primary source of funding for that equipment? The article suggests we'll have access to a lot more types of pictures six or so months from now.

I'm sure the scientists and engineers would have loved to have stuck some RTGs on Philae, among other things, but there were probably design and cost considerations. The funny part is that it does have batteries, which would be charged by solar light, but Philae had to go bouncing all over the place and not anchor itself, so there's a little difficulty with things right now.

One solution is to send another spacecraft to another comet, using all the nifty information we learned from this mission. :)

There's a lot of battery capacity on Philae and the primary science mission was designed to operate solely on battery power. Which is what's happening now, from what I've read. ESA has been very careful to talk about this mission as a big success, with most of the science goals achieved. Unfortunately because the primary press story was the crazy landing technology and that part failed, it looks like a failure. It's not and I hope once some of the science gets released folks will switch to appreciating how much as accomplished and how resilient the lander has turned out to be.

I'm thrilled by the continued discussion about trying to move the lander with the flywheel or landing gear struts. You're in a low gravity environment, why not try? Sounds like they're concerned there won't be enough power to do anything though, and also wanting to get all the primary science done first before risking anything.

Meanwhile, in the ongoing struggle for women to be treated like human beings.. Emily Lakdawalla, the Planetary Society reporter whose tweets I like so much, has some depressing tweets about being afraid to do some online videos because of all the "vile comments" they might attract.

Philae: The Biggest Jump Ever

So, Philae bounced twice before coming to a halt. 'Bounce' does not quite describe it correctly. Philae did by far the biggest #jump ever. The f*cking tallest, longest, slowest JUMP ever done by a human made object (including humans). Without using thrusters, just by pushing off from a rock. That's something for the Guiness Book of Records.

And Philae was lucky as hell. It jumped about 1 km high and 1 km wide on a rock barely 2 km large. Had it jumped only a little bit more, then it would have missed this side of the comet and probably crashed head first into some other part. Philae jumped off very slowly at about 1/5 walking speed. Had it been twice as fast, then it would have left the comet entirely and it would be lost in space by now.

I don't really have time to properly figure it out, but if Philae masses 97.9 kg and impacted at a speed of 1 metre per second and the comet masses 1e13 kg, how much deflection did that cause?

Like, I know it's going to be micro-micro-micrometers (or quadrillionths of an arc second or whatever) but it's got a long long way to go. might it add up?
Does this count as the first deflection of an asteroid ever achieved or is it such an incredibly tiny amount that it'll make no difference in the lifetime of the universe.

Not an asteroid, a comet, and not the first; that would have been Deep Impact's 820 pound "bullet" which slammed into comet Tempel 1 at orbital velocity.

'Bounce' does not quite describe it correctly.

This seems like someone who doesn't understand the difference between a bounce and a jump, and just thinks a jump is bigger than a bounce.

Coincidentally(?), Berkshire Hathaway is purchasing Duracell. I wonder if there is some social media manipulation going on.

Wouldn't that make Duracell more expensive for them to purchase?

I don't know. They parked an orbiter around a tiny and fast object that's poorly understood, discovered that it had really strange geometry, and still managed to get a lander on it, all involving butterfly-scale gravitational forces. I suspect that perfect missions are a minority, even when we're going to well-studied and familiar places.

They've just got signal from Philae, so the battery lasted long enough for this (possibly) last communication ... I think this means they might try and move it by hopping ...

There's drilling too!

Rotation seems to have been a success. Not sure if that gets Philae into more sunlight.
posted by PenDevil at 3:09 PM on November 14, 2014


Rotation after landing, AND drilling? This is some serious Kerbal shit going on.

Many probes have little LEGO figures attached, I hope in the future the Shapeways Jeb will also come as standard-issue for spacecraft.

If you couldn't handle Up or Wall-E, I would suggest that you not follow Philae's twitter account. Really.

So, is Philae dead? I'm confused.
posted by InsertNiftyNameHere at 4:08 PM on November 14, 2014


Resting. Pining. Preparing for the worst. But not dead yet. And if Philae does die, solar resuscitation is still possible, if that shady area just gets enough sun as the comet continues in its orbit.

(... and if Philae doesn't get too damn cold for too damn long.)

Oh, man. Ed Yong is really taking this badly. Laptop: "Your battery is low (10%)". TOO SOON, LAPTOP, SHUT UP.
posted by maudlin at 4:18 PM on November 14, 2014


The link's still up, but Philae is running on fumes. About half an hour left to LOS, but it's unlikely the battery will hold up.

However, they've just broken out the champagne in mission control...

Aw dang it. ESA pulled off an amazing feat, got some amazing pix and data that I look forward to seeing more of. I sure hope we get a signal back, but I guess we should hope for too much.

@elakdawalla: "The screens in the ESOC's main control center are going dark one by one. Lights out." I'm heading towards maudlin, and then I remember, holy shit I just saw a photo from the surface of a comet. I never would have expected that, and love having MeFi space exploration threads the share the excitement with. Thanks, everyone.

Love the surfaces. And I've been thinking that it's a new type, with so many more small spiky features. I guess they'd be due to lower gravity and the famous jets from near-sun heating. Someone could have predicted them, but now I've got an image of exactly what they look like.

The MUPUS twitter account is one of the best overall collections of what has been going on with Philae.

MUPUS is Philae's "MUlti PUrpose Sensor". It's measuring thermal and physical properties on the comet surface.

MUPUS result summaries are coming in now via the twitter feed--in fact, they are still in progress. VERY interesting:
Results (1) First off: some reported MUPUS results as found in media are wrong. They never asked us. @Philae2014 @ESA_Rosetta

Results (2) MUPUS TM worked fine throughout the whole timeline and sees a very cold steep wall in front of us @Philae2014

Results (3) TM sees clear diurnal temperature signal. Around local noon direct sunlight on that wall caused a steep temperature increase...

Results (4) ... and also steep temperature drop shortly after. Data indicate low thermal diffusivity and fluffy substance @Philae2014

Addressing the questions about that fluffy stuff: have to speculate. Best guess tiny mineral grains and organics fluffy like cigar ash

Results (5) The anchors still below Philae in shadow see the diurnal heat wave as well and at the same time as TM and the solar panels

Results (6) Penetrator was deployed to the commanded distance. Remember that device had not been switched on since 2002

Results (7) Temperature inside PEN dropped significantly compared to status before deployment.Might have hit a pile of stuff on the way out

Results (8) Another instrument saw better performance thereafter - we might have changed Philae's attitude

Results (9) Hammering started as intended in the lowest of 3 power settings (expecting a fluffy soft surface)

Results (10) The depth sensor shows some up and down but no progress. The control loop increased to power setting 2

Results (11) depth sensor still shows no progress. Control loop goes to power setting 3. Still no progress!

Results (12) This means that the stuff is really hard! A very interesting finding, not visible from orbit!

Results (13) We have a secret power setting 4. Nicknamed "desperate mode". Beyond the design specs. We activated it

About the 'desperate mode' The truly genius designer of the hammer, Jerzy Grygorczuk, always said "be careful with power mode 4. And...

Check the twitter feed for the rest of the story!
Video of MUPUS at work here, description of MUPUS in Emily Lakdawalla's blog post here, MUPUS details here.

This is going to re-write what we know about comets, IMHO. As near as I can tell, they found a whole lot of things quite different from what they were expecting.

Here is a Storify that has the whole sequence--it will be buried and hard to find on Twitter soon, I fear.

I'm pretty sure there is a story behind that shirt and why it was worn today.

A friend of his made that shirt and she is apparently pretty happy he wore it on the occasion.


Here's her comment on the shirt.

Can't tell if this was linked here already, but Emily Lakdawalla posted a story on her Tumblr about getting to be in the control room with the mission team, watching as Philae went to sleep, or as "the main bus voltage plunged", as the scientists say. It's a sweet story about a robot.

Not sure of the source, but here's a montage of images showing the lander's bouncy journey. Bad luck, or maybe it bounced into the cliff and stopped. Also quite a carom after the first bounce. (via burritojustice)
