Knew I recognized him.
Overall I'm really enjoying this series so far. It's not as cartoony as SG1/SGA became yet not as dark as BSG - the writers seem to have the mix just right at the moment.
I agree with the thoughts that Rush is just a socially awkward, slightly obsessed science geek rather than some sort of evil calculating villain! I think the fact that we're learning about the secondary characters as well, as opposed to them being one-dimensional disposable cutouts is another point in the show's favour.
Which brings me neatly to my last point.. good as it is so far, it IS just a TV show. I'm all for discussing the questions thrown up (that's what keeps viewers coming back after all), but there is a danger of over-analysing it and expecting too much - we're only 5 episodes in after all, and as someone else said, a certain suspension of disbelief is a requirement for this sort of show.
Just my 2c though... I'm glad Stargate is back anyway!

He also suggested the slingshot and orders the pilot to turn immediately and head to the planet. Mathboy doesnt come into it until they need the course calcs worked out. So Rush definitely saved them.

TOM!!!! Hi
Long time no see.
Tis correct on the mathboy helping out. It was Rush that came up with the idea. Eli, just started doing the math the moment rush suggested turning back to the planet. Working as a team and being on the same wavelength.
Called the Destiny being solar powered the moment they said they where heading to the star. But TBH, it just made a load of sense to have it recharged off the star. Lets face it, no power supply that works in the Ancient catalogue could hold up that long.
What I really want to know now is, are they at full power? How long will the charge last? Can they now get into exposed area's?
Also got to agree with the theory of a lot of damage on the right wing. Look at it on Sky HD today and it really looked like damage.0 -

Well, yeah.
When they (the writers) just pull stuff out of their arses and make it up as they go along...well that I can accept. When they instead, as they've shown with SG:U, try to employ real physics and 'real' situations, they could at least have the good grace to try and get it right!0 -

Can you explain to me how the slingshot maneuver as depicted in that episode couldn't have worked in your opinion?
The concept is based in fact (Apollo 13 used the moon to slingshot back to Earth I believe?) and since the shuttle has fairly substantial engines from what we have seen, I think it is entirely plausible. (My thinking comes from rudimentary calculations based off the orbit of the ISS by the way)
Edit: Just to say, I'm not saying you are wrong, in fact I'm assuming there is a factor I'm missing here. Possibly you feel the planet wouldn't actually increase the thrust of the shuttle very much?0 -

Understanding orbital mechanics is easier than explaining it, as so much of it is counter-intuitive to what we experience on Earth, but I'll try!
I'm working on the assumption that Destiny was performing its own flyby of the rocky planet. Both Destiny and the shuttle were inside the planet's hill sphere. The Hill sphere marks the invisible point in space in which the planet's gravity becomes paramount. Smaller objects within this invisible limit naturally fall into orbit around the bigger object. So, for however brief a time it actually was, they were satellites in orbit of the planet. Their movement was within the planet's frame of reference - that is, during their maneuvers around the planet, they were still moving with the planet on its orbit around its star.
Still with me? Think about the space shuttle - when it flies up to meet the ISS, the shuttle is moving and maneuvering through space, but both the space shuttle and the ISS are still moving with the Earth on its orbit around the sun.
Anyways, both Destiny and the shuttle were in orbit of the planet.
Still with me?
A gravitational assist does not work on the principal of picking up velocity by falling toward a planetary body, as the episode implied. As you fall out of the gravity well and away from the planetary body you very neatly lose all of the velocity you picked up in falling towards it. You instead pick up velocity based upon the planet's orbit around the parent star (see here). In the case of the shuttle, its only net change in velocity, relative to the planet and Destiny would have come from the craft firing its thrusters during the course of the maneuver.
And all of that is only the first reason why it would not have worked. The shuttle was already accelerating hard in one direction. Unlike on Earth, there is absolutely nothing to brake against - no air resistance, no friction with the ground. The shuttle would have had to turn around and spend a significant amount of time just slowing down so it could reverse course.
At best, you're talking real hours or even days just to slow down enough and turn around and then complete a slingshot around the planet, by which time Destiny would have been long gone.0 -

Given destiny was after flying through the sun and the planet was far enough away to be habitable for humans I doubt destiny was in it's orbit.Understanding orbital mechanics is easier than explaining it, as so much of it is counter-intuitive to what we experience on Earth, but I'll try!

Yes, it would have. Distance from the sun is moot.
Actually...considering how quickly it crossed the planetary system (hours?), Destiny would have to be travelling at a measurable percentage of the speed of light (0.5-1% (15,000-30,000km/s)). Destiny would have skipped away and gone on its merry way. Velocity affects gravitation. A big, heavy spaceship flying by the planet at the speed of light would have a measurable effect on the planet's orbit, but that is a discussion for another day.
Alright, Destiny might not have been in orbit of the body - consider it skipping by. The shuttle itself was in orbit of the planet. The slingshot would not have done a thing.0 -

I have to laugh at some of these things. Not in a bad way. Just in a funny way.
Some people actually criticised the episode for the fact that at no point did they think the ship would be destroyed! :eek: I should probably put this in a spoiler tag for you guys but here goes............. If the ship is destroyed then the show is over. And thats not gonna happen in the 5th episode. Agree?
There's also a few people wanting Weapons and Aliens and Stargate travel and Ancient technology to be found. SLOW DOWN. There's plenty of time. We've had enough of that in Atlantis surely. I could go a whole season without seeing an alien. Infact I'd love it.
Debating the authenticity of a sling shot maneouver in a sci-fi series involving two imaginary space ships is mental. I like the debate on whether or not its possible with a NASA shuttle but discussing whether or not Destiny's shuttle could do it is like saying "Which weapon could cut through human flesh faster.... A samuri sword or a light-saber!" It doesn't matter cause the light-saber isn't real.
I'm not having a go at anyone, it just makes me smile reading that stuff cause I know I do the same thing sometimes. I've had hours of conversations about Marty McFly's time travelling in BACK TO THE FUTURE.
I'm really enjoying SGU. Takes my mind off real life. Loving the soundtrack too but not a patch on BSG's.0 -

all that stuff
Aw, thanks for ruining it for meAlmightyCushion wrote: »Given destiny was after flying through the sun and the planet was far enough away to be habitable for humans I doubt destiny was in it's orbit.
They could see Destiny from the shuttle, so it was fairly close.Actually...considering how quickly it crossed the planetary system (hours?), Destiny would have to be travelling at a measurable percentage of the speed of light (0.5-1% (15,000-30,000km/s)).
That's something that most Sci-fi shows skip over, the fact that at sub-light speeds you'd get pretty much nowhere, slowly. BSG and Firefly both payed heed to it, everything else just seems to assume you can get from Saturn to Earth in a few minutes.
You really do have to suspend all disbelief when watching a show about traveling to other planets, especially when the natives all speak modern English.0 -

Thats the spirit. More of this positivity is needed. YAY.
Just a quick question...... Does anyone have a theory on why Blonde doctor wanted to quit her job? Does she have feelings for Colonel Young? I got that impression.
It does seem that way although the cynic inside me says it was with someone from theLucian Alliance and she like knew the attack was going to like happen and wanted off the base and now shes like mega pissed that shes like stuck on a ship on the like far side of the universe when she was like supposed to have like received a huge bounty for outing the like secret location of the Icarus base but then again I really should have like punctuated and thought about this like spoiler alot more clearly than it is currently written eitherway you get the point, likethe optimistic me has me hoping that it'sLt Boobs

You may be right. LtB does seem a bit ballsy. If ya get me. But LTB wasnt she riding yer limeboy in the first ep? Bisexuals!!!
As for the former no I doubt anybody knew about an attack on Icarus. It caught everyone unawares. We arent even 100% on whether it was the LA or not. Could have been a splinter Jaffa element or a leftover minor gou'ald for all we ****ing know.0 -
Not too much to add to the thread but have to say i'm really enjoying the show more as the ep's go on.
It was easy to know the ship wouldn't be destroyed, but for a couple of minutes i did think the people on the shuttle might be lost, most of the main characters weren't on it, and they could probably show up at a later stage. But the show has the edgy feel, a main character could be killed off just to keep that feel.
9/10
OH and i seen this on another forum, worth posting again:D;

Answers here : Louis accidently let it slip and supposedly it should have cut out of the interview:D (Doubt that's true though)Guess the obvious thing was the right thing 0
