Default Time to Think ‘Horizontal’ for Future Space Launches

"Is firing a rocket from the ground straight up
into space the right way to do things?

It sure was in the 1950s and ‘60s and it
persists today. But it’s still expensive, fraught
with technical risk and dwindling into
obsolescence.

There could be an alternative on the horizon,
however, that incorporates the concepts of
railguns, scram jets and kinetic launching
into an innovative, reusable space launch
system for unmanned cargo."

Naw the sleds were being recycled by the poor. Even
though the occasional sled would hit and kill as the
primary form of twenty-third century retirement for the
underclasses.

For those too young to remember this TV series, here's a colorized
version of the spacecraft taking off from the launch rail and ditching
its booster sled: http://www.youtube.com/watch?v=sBZN3c7O9wc
The whole concept owes a lot to Sangar's Antipodal Bomber design from WWII.

Reusable boosters are smaller lighter and less costly - according to
Lockheed.

http://www.military.com/features/0,15240,220472,00.html

VTOVL is the way to go.

http://www.scribd.com/doc/30943696/ETDHLRLV

to launch significant payloads cheaply.

http://www.scribd.com/doc/35439593/S...-Satellite-GEO

We start with a small sub-scale version built around RL10 engine parts
making up an annular (circular) aerospike engine. This lifts 35
tonnes into LEO.

With this capability we build a telecommunications network that earns
significant money at the outset. We also use it to test on a small
scale, solar power satellite systems.

We then build the larger system outlined above, capable of lifting 700
tonnes into LEO. This supports deployment of the 10,000 MW power
satellite system described.

The smaller vehicle fleet is then used as a test bed for improved
performance. Suspending lithium particles coated with frozen methane
increases energy density and fuel density. Mixing fluorine with
oxygen increases energy and fuel density further.

Once the pump and injector and thrust chamber changes are made to
operate reliably, along with procedures to minimize adverse effects of
exhaust - the smaller system increases to 100 tonnes LEO capability
and when applied to the larger system, 2,000 tonnes to LEO are
possible.

This increases our capabilities - to 30,000 MW at Earth and over 1 TW
satellite pairs.

We then migrate to laser propelled rocket engines for further
improvements.

Do you really have to thread-jack at every opportunity to push your
napkin drawings? No rational person here is taking you seriously.

But since you're never going to be officially in charge of anything
that involves a cent of public loot, or even that of private investors
loot, and those you keep sucking up to as right here within these
Usenet/newsgroups have no honest intentions of ever doing anything
except being as topic/author stalking, naysay and obstructive as
possible, means that you're screwed as well as that of humanity simply
gets to do without anything Mook.

Too bad that you seem to think there are no serial bad guys, no nasty
cabals, cartels or special interest conspiracies, and no need of ever
revising history in order to reflect the actual truth(s) of what has
been holding us back. Instead, you just keep proving to us that the
past, present and future are simply as good as it's ever going to get,
because William Mook is just another silly flash in the pan that'll
never deliver any benefit to humanity unless you manage to outlive
most everyone else.

"A new scientific truth does not triumph by convincing its opponents
and making them see the light, but rather because its opponents
eventually die, and a new generation grows up that is familiar with
it." / Max Planck

Good luck with that longevity plan of yours.

My system uses an inflatable thermal protection system to slow below
sonic speeds and fold away wings when gliding below the speed of
sound. A tow plane flying down-range snags the booster as it is
gliding down-range with a tow line and tows it back to the launch
center. There the booster is released. The engine re-starts at a low
thrust setting, as the booster climbs into vertical position. It then
settles down tail first, like the old tail sitters from the 1950s - on
a mobile landing platform. The wings and thermal systems retract and
the booster is readied for another launch.
