No... Listen to me now.
If you can't confirm my observations, you must have the coordinates wrong,
because there is definitely something up there.
For the tenth time, it is in Cassiopeia.
Declination 61 degrees, six minutes.
Right ascension two hours, 48 minutes.
That's impossible.
Yes, I'm sure.
Listen. Listen, I am not some crackpot phoning in a UFO here.
I am the cofounder of the Northern Susquenita County
Amateur Astronomical Society. I've been tracking this thing for three nights.
Whatever it is, it is very big, it is very close,
and I will not shut up about this until...
Never mind.
This image was generated from satellite observations made in the last few hours.
The asteroid has an irregular shape,
but we've calculated its length from end to end
to be approximately 137 kilometres.
I've seen this movie. It hits Paris.
It'll strike somewhere in the Arctic Circle. Probably Greenland or the Barents Sea.
Nobody knows this but us? How is that possible?
The asteroid was discovered by a civilian
who's since been "persuaded" to keep it quiet.
The reason no one else has detected it is that the object's path is highly atypical.
It's outside the plane of the solar system
occupied by the planets and the asteroid belt.
In fact, it's a fluke that anyone saw it at all. We got lucky.
I don't see how in any way this is lucky.
Well, seven or eight years ago, there'd be nothing we could do about it.
The Stargate opens other options for us.
A little help from our friends?
- Yes, sir. - Perhaps the Tok'ra could assist.
They've been on the run since the Goa'uld attacked their base at Revanna.
We've already sent a message asking for their help. There hasn't been any reply.
The Asgard owe us a favour.
We could contact them through the K'Tau.
The treaty with the Goa'uld means the Asgard cannot prevent natural disasters.
The Goa'uld tried to make the Tollans send a bomb through the iris.
- Screw the treaty. - Well, one of our allies will help.
I hope you're right.
Otherwise, in 11 days and 16 hours, all life on Earth will be wiped out.
I'm afraid the answer is no.
Come on, guys. Throw me a bone here.
The Protected Planets Treaty leaves no room for interpretation.
They tried to attack us.
It was the Tollans who attempted to send the explosive device through your iris.
By whose order?
The System Lords deny knowledge of this incident.
Of course they deny it.
The Treaty does allow for the arbitration of such disputes.
We would need to assemble a commission of inquiry,
consisting of equal numbers of Asgard and Goa'uld representatives.
We would also need corroborating testimony from the Tollans.
That's gonna be a problem,
as they've been wiped out by the Goa'uld.
That is unfortunate.
And I suppose, when Earth gets hit by that rock and we're all wiped out,
that's gonna be unfortunate too?
Very.
- And after that I kind of lost my temper. - What exactly does that mean?
Let's just say Jack made a reference to Freyr's mother.
We'll discuss his diplomatic shortcomings later.
Right now I'd like to know our options.
I say we nuke it ourselves.
We have sufficiently large-yield warheads to deflect it,
but we don't have a delivery system which can reach the asteroid in time.
The cargo ship I crashed on Revanna must still be there.
In how many pieces?
Our understanding of Goa'uld technology has improved. We might be able to fix it.
- How much time? - With the right team, two days.
I'll assign anyone you need, Major.
Assuming we can fix it, how long will it take to fly back to Earth?
Revanna's not exactly next door.
Even pushing the engines past 100%, it would take eight, nine days.
- Leaving little margin for error. - Then let's get started. Dismissed.
Colonel, I have every confidence in SG-1's abilities.
However, as a contingency plan, the president has ordered me
to begin Alpha team evacuations through the gate.
Major Davis will be arriving from the Pentagon to coordinate.
- Yes, sir. - If Major Carter cannot repair the ship,
you will report immediately to the Alpha site and assume command.
- General? - No debates on this one. That's an order.
Yeah.
- Good to go, sir. - Teal'c, show 'em the way.
This way.
- This, uh... big enough? - 1,200 naqahdah-enhanced megatons.
- That's a lot? - It's the most powerful warhead there is.
It's the equivalent of one billion tons of TNT.
That's a lot.
Hey! What are you doing?
I'm sorry, I can't do this. I can give you a list of some good engineers.
Come on, Spellman. I do this every day.
You don't understand what happens to your body when you go through it. I do.
- We need you for this mission. - It defies the laws of physics.
Spellman, you're going.
It doesn't look so bad.
Our first priority is auxiliary power. Then it's hyperdrive and life support.
Right.
Is there a rest room?
My first priority.
Ah, they'll fix it up.
- I'm confident. - Me too.
As am I.
I looked again. I still can't find it.
- Did you check the guidance system? - Twice.
OK, I guess we'll have to assume that there isn't one on board.
- One what? - We're ready to attempt an engine start.
Yeah, fine. Assume there isn't one what?
Recall device.
The X-301? That was you guys?
You must admit it performed beautifully
until you and Teal'c were sent into... deep space.
Yeah!
Nice work.
- Carter. - Attempting engine start.
Carter?
That's got it, sir. We're good to go. I'll repair the remaining systems on the way.
Once you get to the Revanna gate, dial the Alpha site. They're expecting you.
I think I speak for about six billion people when I say "good luck".
You too.
- I'm gonna wanna talk to you guys. - Teal'c, try to take it easy on the engines.
Why?
I'm slightly concerned that if we push them too hard and they burn out
before we reach escape velocity,
we'll come crashing back to the planet.
- I'm confident. - Me too.
As am I.
I appreciate that, but if we don't hear from SG-1...
- We're getting a message, sir. It's SG-1. - You were saying?
The signal's being relayed through AF SATCOM. Audio only.
- Pipe it through, Sergeant. - Yes, sir.
Please respond.
SG-1. This is General Hammond. Please respond.
Sir, we've just dropped out of hyperspace.
We should reach the asteroid in a few minutes.
We're relieved to hear that, Major.
You sent engineers to the Alpha site ten days ago.
The ship's barely flying as it is, sir. We're lucky we made it this far.
Understood. Proceed with your mission.
Yes, sir.
All right. 39 minutes before impact, the asteroid will reach the fail-safe position.
After that point, it'll be too close to Earth for the explosion to deflect it.
That leaves us three and a half hours.
So we just drop off the bomb and... what?
Our scans show that the asteroid is pitted with impact craters and fissures.
We fly the ship into the deepest crater we can find at a right angle to its trajectory.
The crater should direct the explosive force of the bomb like a rocket nozzle.
When we're just above the surface, we bring down the MALP with the bomb.
Then we land, and two of us go EVA.
That would be you and me.
We walk the MALP down into a fissure at the bottom of the crater to focus the blast.
We set the timer and then we get out of there.
- Piece of cake. - There is one other thing.
We're about to pass through the Leonids: a cometary trail Earth crosses sometimes.
The shields should help protect the ship.
Anyone caught outside is gonna have to find cover, and fast.
What was that?
I'm having difficulty with the sub-light engines.
Yes, you are.
Sir?
- What is it? - An overload in the control systems.
- Backups? - We don't have any.
Sir, we just lost SG-1's signal.
SG-1, this is Hammond. Do you read me?
SG-1, please respond.
How's the head?
The sub-light engines have shut down.
Big asteroid problem here.
Try using manoeuvring thrusters to slow us down.
I am. It's not working.
Daniel is correct. Manoeuvring thrusters appear to be insufficient.
They're all we've got.
Sir! Deep-space tracking still has a fix on the ship,
but we show them approaching the asteroid way too fast.
- Any time now. - The thrusters are in full reverse, O'Neill.
- We're coming in faster than we should. - Yes.
Faster than we should with thrusters at maximum.
90 metres per second.
80. This rate of deceleration isn't gonna cut it. We're gonna hit.
- What happened? - We're inside a deep crater.
50 metres per second.
40.
30.
We stopped descending.
No, I understand. Thank you.
Sir?
We got a message from NASA. According to their calculations,
SG-1 has crashed into the asteroid at over 60 metres per second.
- Do they have confirmation? - No, sir.
It's an estimate based on the ship's last known position.
Any chance of survivors?
At that velocity, sir, it's...
it's very unlikely.
Sir.
If this is true, and the mission is down,
we're out of options.
It's time to call the president.
- The sub-light drive is down. - As are shields and communications.
It might be easier to list what is working.
- The bomb? - It's good to go, sir.
If it comes right down to it, we can detonate it right here.
- What's our position? - Personally, I'm against it.
We're about five metres above the surface at the bottom of the crater.
The rings will be functional at that distance.
All right. Here goes.
Let's suit up.
- Carter, you all right? - I'm fine, sir.
You took a pretty good shot. Why don't you sit this one out?
- No, I'm fine. Really. - Teal'c and I can handle it.
Yes, sir.
No, sir. There's been no response on the radio.
If they crashed, there should have been visible evidence. We've found nothing.
Frankly, sir, if SG-1 survived and they manage to complete their mission,
then no one needs to know any of this ever happened.
If not, nothing anyone can do will make the slightest bit of difference.
Going public now would only serve to create panic.
Yes, sir. I know how you feel.
My place is here.
Thank you, Mr. President.
Depressurising airlock.
You'll experience very little gravity.
The asteroid's surface is mostly iron and your boots are magnetised,
so you shouldn't go spinning off into space.
That's very reassuring, Carter. Thank you very much.
Depressurisation complete. Opening outer door.
I'll drive.
What is it?
Our approach was a lot faster than it should have been, even on thrusters only.
I wanna check something.
We can proceed no further.
Then this'll do.
Weapon is armed.
Something's not right. The gravitational field is stronger than we thought.
So?
Gravity is determined by mass. Mass is determined by size and composition.
So?
So the core must be made of something a lot heavier than nickel and iron.
What was that?
We're passing through the Leonids sooner than I expected.
Colonel O'Neill, what's your position?
We're almost out of the cave.
Better stay where you are, sir. We're taking meteor hits.
Carter, any chance of getting those shields in play here?
We're working on it, sir. Stand by.
Daniel, try to reroute power from the hyperdrive.
Bypass systems are all blown.
Hull breach! We're venting atmosphere!
Carter.
Any progress on those shields?
Stand by, sir.
That's it.
And now there's two more.
Carter! Daniel! This is O'Neill. Please respond.
Carter!
It appears the meteor storm has subsided.
Go.
Carter! Carter! Daniel!
Report!
O'Neill, these readings indicate zero atmosphere within the ship.
Hull breach?
If that is the case, Carter and Daniel could not have survived.
Open it.
I got nothin', Teal'c.
The hull has been damaged in several places.
What are you considering, O'Neill?
They're in the escape pods.
I have identified the breached areas of the hull.
We can begin repairs immediately.
All right.
- General. - Doctor. Shouldn't you be offworld?
I'm leaving with the next group, sir. Your name isn't on the list, sir.
- That's correct. - May I ask why?
If that asteroid hits, the only chance for the survival of the human race
will rest with the Alpha site.
We limited their number because they'll have limited resources.
Everyone will have to contribute.
Your experience makes you more than qualified, sir.
I appreciate what you're trying to do, Doctor. But my decision is final.
Yes, sir.
- How you feelin'? - Not bad.
- That's great. Let's go. - Sir, I don't think we should leave just yet.
Somethin' to do with gravity.
It's too high. Higher than it should be.
I need to reconfigure the sensors to find what the core is made of.
- Oh, here we go! - I'm sorry, sir.
Oh, come on! We came, we saw, we planted the bomb.
We had a little fun with a meteor shower, we went home. It's a great story.
Isn't it?
I was right.
- This could be a problem. - Indeed.
I don't wanna hear it.
Sir, the asteroid's core is composed almost entirely of naqahdah.
Of course it is.
- It makes up 45 per cent of the mass. - Of course it does.
Naqahdah does not occur naturally.
Which is why I never even thought to look for it.
Sir, this must've been a Goa'uld setup.
To betray the Protected Planets Treaty with the Asgard is almost unthinkable.
What?
The Goa'uld set the asteroid on a collision course to look like a natural disaster.
They knew the only way we could stop it would be with a nuke.
So... what happens when that bomb goes off?
The explosion will be enhanced by the naqahdah, to the force of a small nova.
This close to Earth, it'd be enough to set the atmosphere on fire and boil the seas.
- OK. This was not in the movie. - If we deactivate the bomb,
and the asteroid passes the fail-safe point, there's no turning back. Are you sure?
Well, I... I can't be 100 percent...
We don't have a lot of choices here.
We're damned if we do and we're damned if we don't.
The asteroid itself may be sufficient evidence of a treaty violation.
Right. The Asgard can intervene.
- We have no way to tell them. - We do if you get that radio on line.
Teal'c, suit up.
OK, try it now.
Stargate Command, this is SG-1. Do you read? Over.
Nothing.
I don't know what else to do. The radio's working short-range,
but there's no way the signal can penetrate this much solid naqahdah.
Ah, crap!
The bomb has yet to be deactivated.
I can see that, Teal'c.
Perhaps the code is incorrect.
Yeah. Carter, come in.
- Go ahead. - Confirm the deactivation code for me.
03310310.
Yeah, that's it. Nothin'.
- Is there a problem, sir? - There was a cave-in.
Seems to have damaged the keypad. It's not accepting the code.
Other than that, everything's... fine.
- How much time is left exactly? - Under three minutes.
Sir, you're gonna have to open up the bomb and deactivate it manually.
First remove the casing around the timer. There should be two screws.
Yeah. I got 'em.
Got it.
Now find the wires leading from the timer to the detonator, and cut the red one.
Carter. They're all yellow.
- Say again. - There are five wires, all yellow.
- Maybe I should cut 'em all. - Sir, if you interrupt the wrong circuit,
it's the same as telling the bomb the timer has reached zero.
Yeah. I knew that.
I'm sorry, sir, but you're just gonna have to cut them randomly.
Yeah. I knew that too.
- How's it coming, sir? - I've cut three.
I've got two to go.
I'd like to take this opportunity to say...
this is a poorly designed bomb, and we should say something when we get back.
I agree, sir.
Sir?
We're still here.
20 seconds to fail-safe.
Still no word from SG-1?
No, sir.
Ten seconds.
Asteroid has passed fail-safe.
Very well. Major, Sergeant, take your positions with the last Alpha group.
That's an order, Sergeant.
Yes, sir.
General.
I haven't been relieved of this command, Major.
Yes, sir.
Good luck.
We get communications back yet?
Sorry, sir. The only way would be to pull the components
we used to fix the hyperdrive. It would take hours.
- What, then? - Well, we have a couple of options.
Number one, give up. Use what's left of the power to get to the nearest gateworld.
We might make it. Then we head to the Alpha site.
- Number two? - We take off and hope that our signal
can be picked up by the Asgard in time to inform them this was a Goa'uld attack.
- There's not enough time for that. - I know.
- Is... there a number three? - There's no three.
Maybe there is. Teal'c, you said naqahdah wasn't native to our solar system.
Which means the Goa'uld must've towed it by ship.
- A mothership. - Daniel, that's it.
- What's it? - We don't have a mothership.
- It only has to last a few seconds. - What only has to last a few seconds?
Choice three, sir. Expand our hyperspace field to encompass the entire asteroid.
We take it out of normal space long enough to avoid the collision with Earth.
- Is there a four? - I know it sounds far-fetched, and... it is.
- Ride an asteroid... through Earth? - Yes.
To the observer, it would disappear on one side and reappear on the other.
The problem is it'd take every ounce of power we've got.
The field would have to be expanded far beyond its usual envelope.
- It could cause the engines to explode. - Explode?
Even if we survived the engine overload, we couldn't take off again.
We'd have a couple of hours of life support, and that's it.
But you think this is... the best shot we have at stoppin' this rock?
Yes, sir. I think so.
Well, that's the plan, then.
I really need more time to make the calculations.
Well, Carter, now might be a good time.
Almost.
Now?
If I engage too soon, we'll reappear right inside the Earth.
Carter, I can see my house.
Engaging hyperdrive... now.
We're there.
The computer confirms we have emerged from hyperspace
on the other side of the planet.
Yep.
Plan three.
Works every time.
Yes, Mr. President.
Yes, sir.
From what NASA and SATCOM tell me, it looks like the asteroid just disappeared.
I don't know, sir, it may have been the Asgard.
But it's my opinion SG-1 had something to do with it.
So... two hours of life support, then what?
Hammond'll find us.
- I'm confident. - Me too.
As am I.
The sensors are picking up a vessel approaching.
- It appears to be another cargo ship. - Goa'uld?
I do not know. The ship is taking up position directly above us.
I'm Jalen, of the Tok'ra. We received your distress call. Can we render assistance?
Well, you know, it's not like we don't have everything totally under control here,
but...
Sure. Render away.
