did you guys see that comet getting blowed up?

We don't really have a thread cache for "outer space", do we?

― nickalicious (nickalicious), Tuesday, 5 July 2005 16:37 (nineteen years ago) link

So, um, does this mean we're at war with SPACE?

Yeah, I was kinda surprised they weren't worried that this massive collision might screw with the comet's normal orbit. I guess space is just bigger than us like that.

something that weighs 350 kilograms is not going to affect the orbit of a comet that is NINE MILES WIDE. I don't understand how anyone could think this is "dangerous" or "crazy" (or some sort of expression of American militarism) - its just boring old science.

You don't think aliens might see this as an act of aggression?

― Huk-L (Huk-L), Tuesday, 5 July 2005 16:46 (nineteen years ago) link

what if the comet is made of lint?

Well, we know the relative speed. If someone gives me the mass of the comet, we should be able to figure this out. This is not hard.

density of ice = 0.92 g/mL
volume of comet = 4/3 x pi x (4.5)^3

assuming comet spherical/not made of lint etc

The real problem the comet probe caused:

Do we know that space ice is just as dense?

The comet is banana shaped.

my calculation = it will land on swansea

― mark s (mark s), Tuesday, 5 July 2005 16:57 (nineteen years ago) link

we have no idea how dense space ice is
which bit of the banana is nine miles wide

my recalculation: baffin island

"The impact changed the magnetic properties of the comet, and this could have affected mobile telephony here on Earth. If your phone went down this morning, ask yourself Why? and then get in touch with us," says Mr Molokhov.

How can I get in touch with you when my phone is down?

HOW DARE YOU RUIN MY DREAMS WITH SCIENCE

― Ned Raggett (Ned), Tuesday, 5 July 2005 17:08 (nineteen years ago) link

Why didn't they try to land it gently? They landed on an asteroid a couple years back.

― andy --, Tuesday, 5 July 2005 17:21 (nineteen years ago) link

That was Armageddon, Andy. This is Deep Impact.

― Huk-L (Huk-L), Tuesday, 5 July 2005 17:26 (nineteen years ago) link

I think they wanted to see what kind of balls it had.

Well if the probe is so insignificant in relation to the comet's size, then NASA should quit trying to make news by bragging about how hard it hit! You look in the papers this morning and it's all "23,000 miles per hour" and "plume of ice scattering across the cosmos" and "DEEP IMPACT" and shit, like they really nailed that thing -- then some Russians backtalk and they're all "whatever, it was like a mosquito on a truck windshield."

NASA in clumsy PR SHOCKAH

― Shakey Mo Collier, Tuesday, 5 July 2005 19:14 (nineteen years ago) link

Yeah, you can't talk up big collisions you've created in outer space, it kinda worries people.

― nabisco (nabisco), Tuesday, 5 July 2005 19:15 (nineteen years ago) link

C'mon, guys, these are socially awkward scientists, they were probably blushing and kicking the ground while giving their press conference. They're so cute, give them a break!

we now have the technology to blow up the moon.

WE CAN AND WILL BLOW UP THE MOON.

"Now that we have succeeded at hitting a rock the size of Manhattan with a computer-guided probe, maybe we'll be left alone long enough to return to the research that really matters to us: pointing our space telescopes at Lindsay Lohan's tittays."

No, I think one of the purposes of this mission was to slam into the comet and expel plumes of comet-material and analyze those emissions (by observing the impact with a telescope).

Still, the explosion is large enough to tell us something about the composition of the comet, but not nearly large enough to affect its orbit.

So, like, we're just pulling our punches to see what we're up against.

― Huk-L (Huk-L), Tuesday, 5 July 2005 19:31 (nineteen years ago) link

Yes. Bruce Willis will be along any minute to help analyze the data and decide on the next course of action.

― MindInRewind (Barry Bruner), Tuesday, 5 July 2005 19:36 (nineteen years ago) link

That comet could have been populated by ice people!

― andy --, Tuesday, 5 July 2005 19:40 (nineteen years ago) link

they broadcast the impact live at Chabot Science Center's MegaDome, we tried to go but they sold out the room

a chunk will fall off and land either side of my house meaning i am in a detached property! yeah!
