Title text: Don't worry--you're less likely to die from a space launch than from a shark attack. The survival rate is pretty high for both!

When you get to space and meet a lightning shark, remember that the fatality rate is no higher than the heat death of the universe, and nobody has died of that!

A shark with a can opener would suffice.

I'm interested in the choice of the rocket design. We know that Randall is knowledgable about rockets, so it's probably not random. As far as I know, it doesn't match any of the existing human-rated model or any that is in active development.
Despite the three engines being drawn the same size, the perspective makes it look like a larger central core with 3 or 4 solid fuel boosters

At a first, not so close glance, it reminded me of a Soyuz. It’s definitely not one, though it could have liquid boosters like a Soyuz.

I was thinking it was a Falcon Heavy with man-rated Dragon (2?) atop, still slightly in the future.

But they don't use oblique/centre-hugging booster-top fairings (more seen in older Soviet stacks (ninjaed!)) and you're right that we're probably looking at a symmetry-3 booster set.

But it's a fairly common setup in any KSP-alike. (I've been playing about with such an Android rocket simulator today, by coincidence. Trying to build up a huge framework of docked rocket-cores in orbit. But the simpler nature of being 2D orbits is offset by the trickier control system, without the handiness of KSP's forward projection/intersection.)

Ground Control: Don't get upset Major Tom. I just thought you might be interested in this oddity.

If you're on Apollo 12, you can do both!

To me it looks quite like a Soyuz with the liquid boosters replaced by Proton fuel tanks... but then it is more "rocket doodle" than anything else! I say that having doodled a lot of rockets of various designs whilst bored.

you're less likely to die from a space launch than from a shark attack.


Cause, y'know, everything else about space travel aside from the launch is perfectly simple and safe.

Things like this are really very rare in any area as small as this spaceship, after all.
Oh, Willie McBride, it was all done in vain.

100% of spaceflight deaths to date have happened either during the launch phase or the entry/landing phase. Nobody has yet died in space “proper” (i.e. above the Karman line).

the reason this comic exists is because randall wanted to have a countdown from 20, just so he could sneak in "20..19.." in this, the year 2019.

How would a regular shark breath in space? There's no air 'n space!

Sharks don’t breathe air anyway. They breathe water. There is no liquid water in space.

They have to keep moving forward, as well. Or they undergo vertical re-entry.

Right, so died during something other than the launch.

There is a lot (as earth is in space).

If you have a bubble of water, the outside will freeze by evaporation and you get a sealed bubble (thus you need a sufficiently large bubble to begin with).

The human space suit are cooled by having a porous membrane between water and space, and the ice will clog the pores until the body heat will melt the ice.

Many (or most?) shark species don't need to keep swimming:
"While at rest, most sharks pump water over their gills to ensure a constant supply of oxygenated water. A small number of species have lost the ability to pump water through their gills and must swim without rest." (Wikipedia)
