I'm thinking about all the hair which cats shed all over the place, clogging air filters.

Using the mass driver to get rid of inconvenient rocks is bothering me a lot.
Wouldn't a spacegoing society rather frown on littering their freeways with dangerous junk?

And that's just "in general", like when then were digging the hole in the first place.
In the case of the improvised rocket, aren't they going to end up bombarding their target (their ship!) with rocks long before they get there, possibly doing major damage and certainly ruining any element of surprise?  I mean, at least  SOME of those kicks are going to need to be pretty much with the rocks aimed directly where they want to go, even accounting for orbital mechanics...

No, they're doing (I assume) a hohman transfer, so they'll not be shooting their rocks straight at the little moonlet.

Besides, space is big. This isn't so much like tossing out litter as like the dust kicked up by a car as it travels a road. The chances of a ship accidentally hitting something discarded by a mining device like this are astronomically small.

 and another thing...

Sandy, your screenshot is all well and good but I don't have the post link either. I think it's a permissions issue of some sort. I've run SMF in the past and it's possible to prevent people below a certain threshold of posts from creating topics. If you or whoever runs this forum could check the usergroup permissions for the "newbie" usergroup you might find the problem.

and one final thing...

They aren't strapped in. What happens when they flip this thing over? And how are they going to do it?

They don't have to shoot any rocks while they flip over. It's a change in angular momentum only. And we haven't seen anything to indicate that they have gyros to stabilise that.

So here is a way to rotate a large spaceship that isn't accelerating, when you have nothing better -- attach a rope aft. Go to the fore and kick the ship hard, pushing away from it while holding the rope. Climb down the rope and get back to the ship aft. When you push the front of the ship you start it rotating. When you pull its tail you rotate it some more. Angular momentum is preserved for the whole system, but your own angular momentum and the ship's angular momentum are different.

I actually like the "jetpack" solution that was mentioned. It's considerably easier to control the outcome.

And they used the jet packs, like I thought they would. Slight suspension of disbelief as I would figure they'll need to chase up some rocks that floated out during the flip. I'd have had the mass driver loaded for another shot so I could settle my remaining fuel back into the buckets right away.

I would wonder about the time elapsed. The slower you go, the longer it would take, but the more fuel you would have for maneuvering and course correction.  I believe they have several days of air left before the suits run out of power, but you would like to not arrive on the outside of your spacecraft gasping for air.

Terry, we got a couple that don't shed diddly (yeah, and a couple that will clog a dolphin's lungs), you don't want to know about a few long-hairs that old-age took care of (La Esposa and I tend to keep cats alive until they could vote if they had opposable thumbs, old enough to drink if they had wallets).  Filters is the key, and cleaning them every meow and then.  They take care of the rats that will follow us everywhere, even to Tellus Tertius.

My best bud Charlie we had to put down a couple weeks back.  Age 22.  A shit-load of cat-years caught up with him.  He was suffering and it hurt us.  Especially since he was the last of my late father-in-law's cats.  (Joe's other two cats died in their sleep, but Charlie was in pain).  La Esposa is still recovering.  As am I.

Yeah, I'm a cat person, not a dog person.  Dogs are willing slaves, cats are free individuals that occasionally get parasitic and know who to get stuff from.  Like other veterans.

Been a long time, but as I recall, the ""New Topic" option doesn't appear until you've  posted already in an existing thread.

ding..ding..ding!!

I think you're right about that.

That would explain why I have no New Topic option

AlpineBob on August 12, 2010, 07:49:20 am
But now I've posted and still have no New Topic option:

AlpineBob on August 12, 2010, 08:08:57 am
But here is the reason I went to the trouble of registering:

I would figure they'll need to chase up some rocks that floated out during the flip.

That was my thought as well.  Except for the chasing.
Open buckets at the end of a rotating line segment with minimal gravity = rocks gone.
And chasing them is not a good option.  Better to avoid the problem in the first place.
Perhaps the buckets are gimbaled, or they put covers on them?

I assumed some sort of cover, perhaps a lightweight mesh.  Does it matter?

Bob,

Our forum is set not to allow "Newbie" class members to create new forum topics. It's a provision to discourage spammers. Once you have posted five times in other topics, you will become a "Junior Member" and will be able to create new topics. Sorry for the inconvenience.

As we go along reading the hard skiffy stuff, there's a constant stream of thought experiments. If not for that, I might as well enjoy a romance novel or Hello Kitty.

We're willing to suspend belief for warp drives or hot green aliens, but it only goes so far.

And learning about those zero-g coffee cups was pretty interesting.

Azure Priest on August 19, 2010, 10:01:39 am
"We're going to MISS Dactyl" is the GOOD news?

Oh dear.  This does not bode well.

For the "bad" news, I'm thinking, "the bad guys saw us coming, and all the ships are gone, so we're back to square one."

Or... "I see them, and they're ready for us."

Or... "We can't jump because we used our jet packs to slow down already."

Or as the Blues Brothers like to say they're "really up shit creek without a paddle."

Between reading a page and finishing reading various discussions in the forum, I forgot to mention something that occurred to me when I read page 509: The tail on the three speech bubbles in the third panel seems to point to the wrong guy.
