Weird. Coffee is great, isn't it? I still like William Mook's idea to
use suborbital rockets to launch coffee from remote growing areas, and
parachuting it down to groups of desperate coffee disaster refugees. If
there is one thing that can salvage the VSE ESAS wreck of America's
space program, it's coffee.

of their conditional laws of physics makes even those Xenon lamp
illuminated phony baloney Kodak moments seem like the only truth and
nothing but the truth.
Too bad Kodak corporate doesn't agree, nor do any honest scientist that
are without a NASA (aka MI6/NSA~CIA) barbed hook up their butt and a
thousand pound test lead attached.
Too bad that the regular laws of physics supports the independent
hard-science about our moon.

such as GW Bush.

Actually it was pizzas from space at first, though coffee would work
too.

Cunning use of two contra-rotating rings of aerodynamic fins around the
periphery of the JavaJavelin BallisticBrewer can be used during ascent
to drive gears that grind the beans; and the reentry heat can be used to
brew the coffee as it descends, if a copper heatsink heatshield is used-
so that every pot will arrive freshly brewed and piping hot where needed.
Using genetic engineering it should be possible it implant modified cow
milk glands into the JavaJavelin that will allow the device to
manufacture its own cream as it flies; these will be fed by a glucose
solution that will also be used to sweeten the finished product if
desired. :-)

Next- the use of hydrogen peroxide steam from the JavaJavelin's oxidizer
supply to create an oxygenated cappuccino specifically for the revival
of drowning victims! :-)

Here's more nonsense that's actually representing the very foundation
of our LLPOF NASA.
The Cold Equations

tomcat,
Of that 92% of rocket fuel to orbit is NOT even of what it takes for
going to the moon and back, as that's more like 96~98+% of the total
package, leaving 2~4% for everything else, and it seems as though we
still have nothing as of today that'll come close to that requirement
unless your 20,000 deg. F. capable spaceplane that's 100% composite
becomes real.
http://www.physorg.com/news6341.html
"It's not part of the %92 of GLOW that is fuel burned during ascent to
orbit. It can't even be residual fuel carried by making the take-off
tanks slightly oversized, since these big tanks would be impossible to
keep cold during orbital flight and reentry."
"The second and third stages of the Saturn V actually achieved a dry
mass fraction of about 10%. But these are not complete spacecraft, only
expendable stages without payload or recovery gear."
Face it "tomcat" and to all others that still believe in the tooth
fairy, we never went to the moon (at least not in person), as your very
own math and recent links to other stuff proves there simply wasn't a
sufficient fuel capacity for delivering nearly 50 tonnes to our moon
and of safely getting those folks back, much less alive and without so
much as one new white hair.
For Christ almighty on another stick sake, we didn't even have a viable
fly-by-rocket lander way back then, and guess what else; we still
haven't squat to work with.
Is being continually dumbfounded and is per chance "snookered" your
middle name?
Drastically cutting the inert/dry mass of the SMEs/SRBs is a good
start, and of two staging them SMEs is step No.2. Step three is the
LRn-->Rn-->ION thrusting that doesn't exist because of all the
dumbfounded and thus backward mindset individuals like yourself.

Disposable!? That's wasteful! The JavaJavelin's exterior is made of a
carbon and nitrogen-rich composite material designed to break down
under UV exposure over a period of weeks; as it breaks down, genetically
modified* coffee beans cast into its matrix sprout and generate a grove
of coffee trees that sprout up at the site of the landing.
Since the JavaJavelin is specifically intended for disaster relief, soon
all disaster-prone areas will have thick forests of coffee trees on
them. These will serve as windbreaks against cyclones and typhoons,
their roots will stabilize the ground against the destabilizing effects
of volcanic eruptions** and earthquakes, and the beans they produce will
serve as a source of income for these
far-too-often-blighted-by-catastrophe areas of the world.
In addition, these coffee forests will serve as a constant warning to
the unwary traveler that he stands on perilous ground, and had better be
prepared to die at any moment.
This will keep the riff-raff out.
* Why should the coffee beans be genetically modified? Because in the
future everything will be genetically modified- because it's fun to do.
In the future all animals will be genetically modified so that they have
their scientific names and maximum size visible on their bellies, as my
toy dinosaurs did.
This will be a boon to mankind! If one sees a strange animal, one need
only kill it and look at its underbelly to determine what it was and if
it was up to snuff in the size department.
** I need not point out the excellent fertility of volcanic soil for
growing coffee. So I won't.

Depends on the details.
The structural fraction of a rocket sized to deliver a single cup of
coffee suborbitally would be on the order of the mass of a disposable
soda bottle, so its not wasteful by those standards. Given that its
likely to be ceramic-carbon-metal composite, it can easily be recycled.
THE HEAT IN A CUP OF COFFEE:
A cup of water (250 mL) is heated from 10C to 90C. 4.2 J is required to
raise the temperature of 1.0 gram of water by 1C. The density of water
is 1.0 g per mL. Thus, the internal energy increase is
dE = 4.184 J/(g C) * 250 g * 80 C
= 83680 J or 84 kJ
THE HEAT NEEDED TO MOVE THE COFFEE TO ITS CONSUMER
A foamed ceramic coffee cup, which doubles as a nose cone of a rocket,
atop sufficient hydrogen oxygen to loft it a maximum range. Moving
from coffee growing regions - say 15 degrees North latitude to coffee
consuming regions - say 45 degrees north latitude - we move things over
a range of 30 degrees of latitude. This is 1/12th the circumference of
the Earth, so its 3,300,000 m - So, this requires a delta vee of about
5721 m/sec. Assuming a structural fraction of 5% overall, and an
exhaust velocisty of 4500 m/sec - we can compute that the propellant
fraction must be 0.72 - leaving 0.28 for structure and payload,
subtracting 0.05 for structure, this leaves 0.23 for payload. So, a
250 gram cup of coffee would require a total vehicle of the following
type;
250 grams - payload (cup of coffee)
5 grams structure
782 grams propellant (hydrogen and oxygen)
Now, optimal exhaust velocity occurs at a Oxidizer Fuel ratio of 6:1 by
mass - the stochiometric ratio is 8:1 - so, the rocket is hydrogen
rich, and only 75% of the hydrogen is reacted with the oxygen
propellant - the rest lowers the average molecular weight of the
exhaust - increasing performance slightly. So we can compute that 3.94
MJ of energy is used to transport the coffee from its place or origin
to its place of consumption. This is 50x the energy of brewing the
coffee.
There are 572 ml of liquid oxygen on board and
and 1,862 ml of liquid hydrogen on board.
A total volume of 2,434 ml of propellant.
About the size of a two liter bottle.
If we use gelled LH2 (by mixing in small amounts of methane) we could
cut this volume in half. (the size of a ONE liter bottle)
NOTE ON ATMOSPHERIC BRAKING
Since the time of flight is on the same order as the coffee brewing
time, and since the energy of the vehicle is largely dissapated by
atmospheric heating during its travel through the atmosphere - the
coffee could be brewed in flight during atmospheric braking by
controlled leakage of the heat flux into the coffee carrying
compartment.
COST ESTIMATES - IN FULL SCALE PRODUCTION
The cost of LOX/LH is about 1.5x the cost of the energy to make these
compounds. This comes out to be around 6 MJ - about 1-2/3 kWh - which
at 5 cents per kWh would cost 8-1/3 cents - say 10 cents over all.
The ceramic materials fashioned into computer controls, actuators,
rocket body, rocket arrays, braking system, landing system and so forth
- might cost 2 cents per gram in quantity - and would cost another 10
cents.
The communications to order and target the cup of coffee would be
around 10 cents
The coffee itself, along with the labor and so forth would be another
20 cents.
A total cost of less than 50 cents.
Selling price - $1.50
Delivery time - 5 minutes after ordering +/-
Delivery locale - anywhere on Earth's surface
