(DENN) - NEO 68430256 Identified on Impact Course

[HHAYD]

OOC: At the topic Lolwhut

IC: We propose sending Aerosmith accompanyed by Harrison Ford to activate a nuclear bomb at a precise point under the asteroid's surface which will split it in two and cause it to miss the Earth.

You are going to need lots of nuclear weapons, since the asteroid is very dense.

And worse, if done incorrectly, it could turn into a shotgun mess and destroy a huge chunk of this planet.

We have already suggested this, but it seems GA has different, more complicated plans.

You seem to miss that is has to have the same position relative to the asteroid at all times. An orbit will simply average out all the accelerations around the z axis, and no net deflection will occur. If we simply put a ship in orbit, it would pull it off course, however, the orbit would pull it back on course when the ship was back around the other side of the rock. This is because of a constant reaction force, the reactive centrifugal force, and with a constant orbit, the directional vectors would sum to zero. Placing the craft at a fixed point would avoid this, but would be very difficult, due to need to keep a steady velocity even when under the influence of several forces, and avoid falling into a rotational movement.

Our scientists have been working on the details and we are almost ready to launch the rocket, which will be a three stage main, then with a glide path to the asteroid, upon where it will enter a slow capture orbit, then fire the grapnel, anchoring itself to the rock, at which point the fourth stage, a long burn rocket imparting 5MN will ignite, and with a ten minute burn time, will pull the asteroid far enough off course to miss the earth.

We have also reached the mid point in the construction of our transit and force imparting craft. It is designed to replace the entire satellite launching module on one of our normal GEO launch rockets.

And for all you scientific people, an analysis of the gravitational vs the anchored thrust method.

Gravitational

Assume: 2000kg for the craft. 5 * 10 ^ 11 kg (500 million tonnes) for the rock. 2km for the Orbital distance.

Acceleration of the rock = Gm1 / r^2 = 2000 * 6.67*10^-11 / (2000^2) = 3.33500 × 10^-14 m/s^2. Which means that to induce even a velocity change of 1m/s, you would need to apply that force for 2.99850075 × 10^13 seconds. This is not including the need for the rocket to resist an acceleration over 10 ^9 times larger.

Rocket Tether

Assume: 5 * 10 ^ 11 kg (500 million tonnes) for the rock. 7.8 *10 ^ 6N thrust for the rocket.

Acceleration of the rock. F/m = a. 7.8 *10 ^ 6N / 5 * 10 ^ 11 kg = 1.56 × 10^ -5 m / s^2. An acceleration roughly 10 ^ 9 times greater than that of the gravitational attraction method.

For a one hundredth degree deflection, assuming a velocity of the asteroid of 15km/s only a 2.6m/s tangential velocity must be introduced which would take 1.94 days for the rocket anchor, and about 2.49 million years for the gravitational method.

OOC: Edit. MV, 14 days is nowhere near enough time. Look. A rock like that needs to be moved by about 200,000 km, end result, which for a say 0.01 degree deflection angle, and 15km/s speed requires it start 1,145,915,579 km away, or about 884 days notice.

Even a rather minor 9,000km delfection. (like 1.5 R(earth) and it means the rock would pass under GEO sats) with the time frame you gave us would mean that it would take ~7 days of thrust form the rocket, and then giving us 14 days for it to move in the new direction.

As A GM I am declaring this non cannon. People, feel free to ignore this if you feel like.

OOC: Eggheads always spoil the fun. What makes you think this couldnt happen IRL? Short notice? Maybe we should try to prolong the impact in order to find a solution.

OOC: A one thousand day detection is easy enough, 2000 days warning, heck, if it a sun orbiting asteroid, ~30 years is possible.

OOC: IRL, NASA would have detected an asteroid on collision path years, maybe decades before the impact.

Maelstrom Vortex, your RPed notice time is way too short. It takes days to prepare and launch a rocket, and then even more time to move the asteroid off collision path. I suggest you to extend the RP notice time up to 1000 or 2000 days.

OOC: Is it too short of awarning time? NASA COULD detect the asteroid...if it was looking in the right direction. The problem is there is a LOT of space out there to scan. this is perfectly plausible.

OOC: I definetly disagree. In case you don't know, NASA has had an asteroid detection program ongoing for more than a decade, maybe even twenty years since 1998, and the people working there say that they've only found 40%, and that a large asteroid could still hit us without warning. In fact, they say that there are a lot of asteroids that can be on a collision course with Earth right now, and they don't know about them. Don't believe me? Look it up.

Article that proves they may not detect it until last minute: http://www.mcclatchydc.com/homepage/story/58025.html

More than 5,000 near Earth objects, including 789 potentially hazardous objects, have been identified so far. Johnson predicted that future surveys will find at least 66,000 near Earth objects and 18,000 potentially hazardous objects.

That's how many they've found between 1998 and 2006, only a fraction of what they expect to find.

First, the Shapiro committee is supposed to propose the best way to detect and analyze 90 percent of the so-called "near Earth objects'' orbiting between Mars and Venus that are wider than 460 feet by 2020.

Keep in mind that this has been going on since 1998...

A collision with one or more of these many objects littering the solar system is inevitable, Johnson said. "Once every hundred years there might be something to worry about, but it could happen tomorrow.''

For example, astronomers had only 24 hours' notice of a small asteroid that blew up over northern Africa on Oct. 7. A larger, more dangerous object presumably would be spotted years or decades ahead, giving humans time to change its course before it hit.

>>If a very large asteroid that we have not discovered yet were bound

to hit earth, would we know about it before it hit?<<

Scientists are actively in the process of cataloging the largest

asteroids. As a rule of thumb, the larger the asteroid, the easier it

is to spot as it nears Earth (and by astronomically 'near', it can

still be decades away from possible impact). So, for a very large

asteroid, the odds are quite good that would know about a possible

impact well in advamce -- enough time to devise a defensive strategy.

However, though the odds are good, they are not 100%. A very large

asteroid could, conceivably, sneak through our observation net.

OOC: Thank you. As I said, the problem is they can detect them--but ONLY if they're looking in the right direction.

OOC: Don't other CNRP nations have the asteroid watching program, or did the players never RP them?

If not, then I think this RP is realistic. I don't understand why some RPers can't deal with imaginary damages to their imaginary nations when other imaginary nations are affected or will be affected.

OOC: No, fe nations if any have RP'd looking out like that. They've RP'd space programs, but stated they were for exploration, not simple, massive observation operations.

A nuclear weapon of suitable size can vaporize quite a large segment of this object if detonated near enough. Something on the order of several Tens of Megatons. Any piece that is left unvaporized can be hit again. With the space elevator such a large weapon should be able to quickly get into space and onto the target.

And how do you know it is not going to turn into millions of radiation contaminated metal chunks that are likely to shred huge parts of this planet?

Keep in mind that even if they burn up in the atmosphere, the radiation will still be deposited into the atmosphere.

How much cosmic radiation hits the atmosphere anyway? Or in the Radiation belt around the earth? Or just in Space in general as background radiation?

Turn it into vaporized dust. Or wait for it to hit the planet and make some radiation seem like someone has a sunlamp on in the Sahara.

OOC: Right, so let's have someone arbitrarily come along and make something happen that will destroy 90% of your entire nation and you have no control whatsoever to do anything about it, and we'll see how you react. A rise in the sea level of five feet would swamp most of Florida. Now let's think about a tsunami wave 20-40 feet high. Everything would be gone. Everything I've put a lot of time and effort into. If we want to make this a long term thing, where people actually have a chance to prepare and do something about it, fine. But 14 days? F that.

[Maelstrom Vortex]

ooc: Tsk tsk. Our highest tech member has bailed out without even resorting to his magnificent rail guns. Phail. And there's plenty of possibility NASA would miss something coming at us from an odd trajectory. They do not have full global coverage yet on their tracking. They have blind spots. And finding NEO's an operational art they have yet to perfect.

ic: It is very possible that radioactive charged particles would not enter the atmosphere due to the ionosphere if they're small enough.

[Maelstrom Vortex]

Due to over tuning of our optics it seems an estimate of the objects actual distance from the earth was incorrect. After cross verification with other centers and other methods of range-finding it appears the object is actually 2 months out, not two weeks out.

With 60 days to move the asteroid, we are planning a ten engine craft with a 48 hour burn to move this rock. At that point it will be given a 0.1 degree course, change, which will cause it to miss the earth by 131,193 km, or around 20 of earths radius. We have finished construction of our rocket motors to move this craft, however, to enable longer burn times, we ask Rebel Army if we could place this craft in space with the space elevator so that we can have it accelerate to the asteroid, reaching it faster, with less fuel used.

The Interceptor craft will have ten 8 MN rockets, and enough fuel for 48 hours burn, which will ensure a 26m/s perpendicular velocity addition, which will ensure our success.

We are currently shipping the parts we need to left to space now, and will be traveling via the suez canal for the quickest route to the space elevator.
