Is Europa Too Prickly To Land On?
astroengine writes "A deadly bed of icy javelins — known as penitentes — could be awaiting any spacecraft that tries to land on some parts of the ice-covered world Europa, say researchers who have carefully modeled the ice processes at work on parts of the Jovian moon to detect features beyond the current low resolution images. If the prediction of long vertical blades of ice is correct, it will not only help engineers design a lander to tame or avoid the sabers, but also help explain a couple of nagging mysteries about the strange moon. 'This is a game changer,' said planetary scientist Don Blankenship of the University of Texas in Austin. Blankenship has been involved in NASA's planning process for sending a reconnaissance spacecraft and eventually a lander to Europa."
What part of "Attempt no landing there" don't you people understand?

NASA first priority needs to be a gravity repulse engine.
The Kruger Dunning explains most post on
Haven't we been using explosives to clear the landing one of tall brush, inconvenient locals, and anything else for at least decades now?
Nothing says 'we come in peace' quite like blasting the site flat before touchdown!
.
I, for one, suggest a low altitude detonation of a low-yield thermo-nuclear device at any potential landing sites prior to the landing attempt.
This should glass over the LZ and let any locals know that papa's coming home and he's pissed.

as just mean spirited, bureaucratic and bad tempered. Why else would we have been warned against landing?
Please do not read this sig. Thank you.

I now expect at least Samzenpus (if not every Slashdot editor) to turn in their geek card, in addition to the submitter being banned from all further Slashdot submissions. How on earth (or in space) do you make a reference to landing (or not) on Europa and NOT put in a Clarke reference? What kind of geek are these people?
Just drop a M-121 bomb on the LZ to clear things out before landing.
Take that spacecommies!
America, FUCK YEAH!

... not completely unrelated and not exactly offtopic, but if we ever land there, I'd like the footage to resemble this: Europa Report.
I hope I didn't brain my damage.
From what I read, these ice formations only form at the equator. So....
Don't land at the equator. Problem solved..

I assume Europe is also hard to land on. That would explain why the aliens in Hollywood movies always land in New York or on the front lawn of the White House
And I don't want to tell them how to do their job, but has anyone considered making their space ship out of some sort of "metal"? And maybe put a thing on the bottom that shoots fire out of it?
I'm trying to teach myself to set people on fire with my mind... Is it hot in here?
I put ice javelins in my blender, add some fruit and there you go, a smoothie. So just mount some BlendTec blenders on the bottom of the spacecraft and see if it "will blend". Would be some nice advertisements.

You throw salt out, hover around a bit, then land. Problem solved. Also, if there is salt left over, use it for the margarita glasses - just be sure to bring fresh limes & decent tequila: obviously you won't need to bring the ice.

I'm not surprised Europa is a bit prickly at the moment.
Somehow the article neglected to mention the biggest risk of them all ... the local wildlife!

For your first idea, if only there was somewhere nearby that was made of combustible material that could be collected using some kind of scoop...
"Wait. Something's happening. It's opening up! My God, it's full of apricots!"
How about making the bottom of the craft an inverted cone? Then it can settle nicely in between the spikes.

Genetically modified or otherwise. Send seeds, grow teraforming. Obviously there's lots of radiation, but start with something that turns CO2 into C and O2.
Something kind of pretty so people will want it as a background.
Get ideas flowing about how to get it done!

I think the top of Spain is pretty flat. You could probably land there if you can get nestled under that French overhang.
Other than that, though, yeah, that's way too prickly. The next closest viable landing spot is over on that Brazilian ledge, and even then you'd need to make sure you get a firm perch so you don't slip off and fall to the Antarctic floor below.
My first thought after reading the headline was about the Java IDE, not the Jovian satellite.
Can't wait to see TV news showing Neil Patrick Harris stick a probe into the mouth of a brain bug.

Think Europa is prickly? Unless it's freshly shaven, how about Uranus? *badum tish* (gets his coat)

No-one ever said the Slashdot moderation system was just.
To everyone suggesting blasting the landing zone flat, have you considered what sort of scientific data we could recover from from a site that's been razed with Earth explosives? If this ice is enough to ruin a spacecraft, then anything capable of dealing with it on a scale needed for a safe landing is going to fling contaminating detritus for probably miles. So we could land, and... then what?
I thought it was already well-known that 2001 (the movie kind) was made so that the US Gov't could practice filming the Apollo landings.
Isn't that what pretty much all the following Kubrick films were trying to explain? Little Danny's Apollo sweater... The symbolism of Eyes Wide Shut...

Well, as the third or forth mention of the same joke in the first couple of minutes I think that Redundant was rather just.

Just saying...
Recent observations have brought to light the fact that a large part of the planet earth is covered by tall sabers of what appears to be carbon based material called trees. "This is a game changer" said some asshole who gets paid to think this shit up.
WTF!
What do I have to do to get a fvcking job making up useless shit.
There are three kinds of falsehood: the first is a 'fib,' the second is a downright lie, and the third is statistics.

No need for an actual nuke, any impactor would do the job.
Which, in a dirty solar system, means there are already fresh craters available.

Sounds like my second wife - no fucking point landing on her either.
And for the sake of a single minute he gets modded to +5 Funny and you get down to 0 Redundant.
I'd have modded the first one redundant, because there's no "-1, too obvious, don't waste my fucking time." Nobody gets a +1 funny from me unless I at least grin, and if I think of the joke before you tell me that joke, it ain't funny.
And BTW, everyone in this subthread is offtopic.
Free Martian Whores!
Now, everything you say is perfectly reasonable (except that the "-1, too obvious" doesn't count for me since I haven't read whatever stupid story they're all referencing anyway. Still off-topic though, though "Redundant" is unfair.).
It isn't offtopic, it's a reference to 2001 (or maybe 2010) where we are warned to stay away from Europa. If you saw the movie it's obvious, if not it's offtopic.
