How long would it take a D79-TC Pelican to take off from a city on Earth and fly by itself to Mars? I’m very curious about this and Halopedia didnt offer any answers
Speeds pretty hard to measure in space…but considering the distance would necessitate a 6-month trip by current standards…days most likely, possibly even a few weeks.
There’s inter-planetary shuttles for just that reason Im pretty sure.
In-atmo Im pretty sure their speeds about the same as a Spirit or Phantom, since that is one ungainly body shape and its literally being shoved through the sky by its engines…so, sub-sonic for sure, 600 ish miles an hour?

It’s gonna be faster than that, that would put it at about the cruising speed of a normal commercial airplane. I’d say at least a few thousand mph, since the most advanced fighter jets today can go up to 1500
I never heard of a dct 7 pelican are they in halowars orvthe books

You’ve never heard of the D79-TC Pelican? It’s the ship that made the Kessel Run in less than 12 parsecs.

The D79-TC Pelican is the Pelican model seen in Halo 4 and Halo 5.
Good question

Yeah, but they’re areodynamic and held aloft by their wings. The Pelican is, literally, a flying brick, running on nothing but its engines.
Then again…the F-4 Phantom wasn’t exactly the most gainly aircraft ever and it was supersonic capable…

The D79?
Waypoint’s Universe article on the Pelican actually has some details on it:
> Maximum Speed:
> 417-561mph (671-903km/h)
Now, I don’t know what the dash between the two sets of numbers are supposed to represent. Difference between the standard D79-TC and the G79H? Difference between the D79 and previous models of Pelicans?
Ditto that for the tonnage specification:
> Weight:
> 71.3-89.4 Tons (64.7-77 Tonnes)
Would be nice to have clarification on this matter…
As for the OT, well…
Let’s assume that the Earth is at aphelion and Mars is at perihelion, thus the distance between the two is about 54.6 million kilometers (54600000 km).
The D79 in question has to take off from the ground first… let’s put it on the flight deck of a Gerald Ford-class CVN (why not?). The flight deck of the Ford-class is about 37 meters above sea level (if my calculations are correct - subtract distance between flight deck and keel (78m) and the waterline and keel (41m)… if I’m interpreting those figures correctly).
The ‘edge of space’ is 100km up from the ground (known as the Karman Line). The thermosphere starts at the 85km point and continues until the 690km point. The exosphere goes up to 10000km.
So… add it all together, and that’s the distance the Pelican has to travel. Of course, in space there’s no real ‘top speed’ (outside of c), so the D79 can continue to accelerate freely (just remember that it has to decelerate from that speed near the end of the transit)… but for the purposes of this scenario, I’m going to keep the airframe at the listed speed.
Assuming the aphelion-perihelion distance is between both planetary surfaces, and thus I don’t have to factor in anything else: 60,465.12~ hours - 2519.38 days - 82.83 months - 6.90 years- yeah, nope, by the time it gets there it’s a tomb…
Assuming the aphelion-perihelion distance starts at the atmosphere of both planets: 9999.963km (distance from Ford flight deck to out of Earth atmosphere) + 54,600,000km (distance) + 590km (estimated height of Mars atmosphere, exosphere starts at 200km but has no significant boundary, just tapers away). Distance: 54,610,589.96km.
Time of travel: 60476.84 hours - 2519.87 days - 82.845 months - 6.90 years.
If I messed up with these calculations at any point, please let me know.
But, yeah, the standard Pelican variants ain’t doing interplanetary travel worth nuts. ONI’s Pelicans, however…
Pelicans wouldn’t work well. But a condor would be better.

I thought it was 14.
Well I’m going to explain this with the help of our friend physics,I don’t think a D79 can even leave earth, This pelican top speed is 671 km/h (417 mph) so this means that a pelican is slower than a commercial plane (990 km/h), to escape of earth gravitational attraction the object that is trying to go to space needs to reach a minimum velocity (escape velocity ) Escape velocity varies but in Earth you need to reach the velocity of…11. 186 km/s,or 40, 270 km/h so, I think this explains all, It’s impossible to a pelican and even for a fighter aircraft, this is why we use so powerful rockets nowadays, it’s the only way, But ok, let’s assume that our magic pelican is already in outer space,as I said it’s top speed is about 680 km/h also let;s suppose that Mars is closest to earth as possible (59000000 km) so doing simple math we can say that our little pelican would take 9.9 years to reach the red planet, so that’s it, I recommend you to get a faster vehicle if you want to get there fast ; ) Edit: (Sorry if my grammar isn’t the best,english isn’t my first language,actually I don’t know if you can even understand my post,let me know if I had any mistake)
We’ve seen in the trailers and cutscenes of a pelican taking off from earth to space. I believe it has a speed that can go over a modern rocket.

Only because of the slipspace drive, though.
Which is why I put in that caveat of ONI Pelicans in my other post (since at least two of them have slipspace drives, and it’s been four+ years since they’ve been augmented with such).

Your distance is slightly messed up. It’s not a 59,000,000 kilometer gulf at the aphelion-perihelion mark.

This. Pelicans have been continuously described and shown throughout the lore as being SSTO-capable.
> I believe it has a speed that can go over a modern rocket.
It should be capable of doing so, but with the stated stats…
…
Nothing ventured, right?
