Nuclear pulse jet.

Currently we have two nuclear applications.

The "slow burn" heats water to turn generator turbines. The "fast burn"
eliminates enemy cities.

Do you have more details on "Nuclar pulse jets"? It sounds interesting,
whatever it is.

The British Interplanetary Society proposed the use of a nuclear pulse jet.

Essentially it's a long tube with the clever bits on one end and a bloody
great big dish shaped lump of shielding at the other.

You toss a small nuclear device down the connecting tube and it goes bang at
the appropriate distance from the shield, the large sliding door closing
behind it slightly before.

The resultant kick propels the space craft.

I've seen things you people wouldn't believe.
Barbeques on fire by the chalets past the castle headland
I watched the gift shops glitter in the darkness off the Newborough gate
All these moments will be lost in time, like icecream on the beach
Time for tea.

That's not the criteria for whether the U.S. government "should"
undertake any activity. Read the Constitution.


So a Mars/Jupiter mission accomplishes?

A more perfect union?
Establishes justice?
Insures domestic tranquility?
Promotes the general welfare?

-or-

Secures the blessings of liberty to ourselves and our posterity?

It is the Orion then. An interesting thought. I would prefer a form of
propulsion that has low acceleration but over a very extended period of
time, like an ion drive engine. If you push long enough you can end up
going very fast.

Look at the powers of Congress in the Constutition. No mention of rocket
ships. The government has no business in the rocketship business except
as a means of defense (under the heading of an army and navy).

Read your Constitutional history and jurisprudence before you make such
absurd statements.

I did. There is nothing in the Constitution authorizing congress to fund
manned space flights.

You are quite incorrect.

How is congress authorized to fund manned space programs? Do tell us.

Here are the powers of Congress verbetim:

You misspelled "verbatim."

I told you to review Constitutional history and jurisprudence not just
quote Constitutional provisions out of context. I see you've not done
so. I suggest you start with Marbury v. Madison and then hit the
Commerce Clause. From there you should move to a review of the
governmental rules clause and finally end up with the "necessary and
proper" clause.

Let me know when you're done.
