Well, admittedly so, but that was at the beginning of the decade.

I do remember the moon landing, though. Did something else of note happen in between? ;P

RE: "Did something else of note happen in between? ;P"

Well, actually, no; it was pretty quiet. Just some minor things like the assassinations of JFK, MLK, and RFK; the civil rights movement; the Vietnam war; the Mercury and Gemini programs and the rest of the Apollo program; the Cuban missile crisis, the "British invasion"; "long hot summers"; minskirts; the original Mustang, the peace movement; hippies; the rise of feminism. As I said, other than those, it was pretty quiet. (smile) Almost as quiet as the '50s. (smile)

The moment NASA bowed out of another moon landing, the gauntlet was thrown down. It is now only a matter of time before private enterprise fully steps up to the plate. The moon has a lot of potential for the human race. Ships can be built there that will not have to escape a large gravity well, space telescopes can be built there with no atmospehric interference and further manned exploration will be possible on a larger scale than now. The one major stumbling block we have now is that we have no viable power source yet to make thsi a reality. Oil and solid rocket fuel will no longer cut it and sending up seven people at a time is inefficient. Though we can build modernized spacecraft, rocket technology is laregely unchanged since the 1950s. We need nuclear fusion power if we are going to expand into space and hopefully General Fusion will be the company that leads us there. I see governments having a much smaller role regarding space because private enterprise is more dynamic and efficient.

It was more like the government, namely the Nixon Admin that bowed the USA out of the moon race after Apollo 17. NASA had plans for putting a 50 man lunar base, mars missions, and more. All of it was dropped from the budget proposals during the 1971-72 time period. Only the space shuttle which was part of NASA plans, was approved. The shuttle made sense at the time because the main obstacle to human spaceflight in 1972 is the same one that exists today. Cost of access to low orbit.

The private sector has to get the cost of getting to low orbit way down before any of the ideas your mentioning can become reality.

"The private sector[*] has to get the cost of getting to low orbit way down before any of the ideas your mentioning can become reality."

[* asterisk added] The private sector, or anybody else, has to...

As in, whether government does it, private enterprise does it, they do it together or they do it separately, the launch costs have to come down, down, way the %^!@ down if any of this stuff is to be done by anyone.

Right. Regardless of how they do it, the cost of access to low orbit has to come down if human spaceflight is to resemble the visions of "2001, A Space Odyssey" and become a viable commercial enterprise.

NEW FLYING TEA KETTLE COULD GET US TO MARS IN WEEKS - NOT MONTHS
NASA researchers and Boeing "are laying the groundwork for a propulsion system that uses powerful pulses of nuclear fusion created within hollow 2-inch-wide "pucks" of lithium deuteride... The plan is to "slapshot" them with plasma energy, fusing the lithium and hydrogen atoms and releasing enough force to ultimately propel a spacecraft ..."

Thanks for these links. I'll be interested to see what comes of the tea kettle. And of course every new tool for studying exoplanets is welcome.

RE: your link

I'm sorry to point this out, but the link that you've posted is to an article that's about a gravitational lens effect caused by a galactic cluster that's 10 billion light-years away. Here's the link I think you meant to post:

You're welcome, Sailor. Let's hope these revolutionary ideas don't die on the vine.

Thanks for the correction, Walter. I've corrected my above post. I have trouble getting to Universe Today sometimes, and I've also had trouble switching screens within it and getting the new URL to pop up.

ENTERTAINING IN ZERO GRAVITY
Don Pettit stayed on the ISS for six months. Some of his (hilarious) wisdom on how to entertain in zero-gravity is definitely worth your consideration. (Always clean the food sissors, that open the food pouches... Always put out new velcro tape to park packets of food... Break out the best food and drink you've been hoarding, like the artificially flavored, artificially colored, sugar-loaded, fruit-replica drinks.)

Enjoy!

OBSERVATION AND MEASUREMENT OF A 59 MILLION LIGHT YEAR LONG DARK MATTER FILAMENT
"Researchers have directly detected a slim bridge of dark matter joining two clusters of galaxies, using a technique that could eventually help astrophysicists to understand the structure of the Universe and identify what makes up the mysterious invisible substance known as dark matter."

Whoever wrote the article is obviously unaware of the 2008 detection of numerous filaments by the team led by Liping Fu of the Institute of Astrophysics in Paris using data from the 3.6-metre Canada France Hawaii Telescope (CFHT) in Hawaii.

What's with all the nasty comments on that article? Oh well, at least now I know it isn't just Americans who fall for the old "I'm COOL because I'm an AS$#&%@!!" idiocy. Then again, I've already found that Americans have no monopoly on most forms of idiocy, including blind nationalism. We're *capable* of all of them, but so is everybody else.

I read "by 2014" and "by 2020" and I'm like, "AAAHHHHGG!!! So... Slow..." But I realize that going into space and doing anything useful there isn't easy (or we'd all be doing it already), and better slow and steady than killing the whole industry (and killing a lot of people) by trying to prove how fast you can be.

So I wait. I will eat some more vegetables, and I'm glad I don't smoke.

Probably in part unhappy passengers of Virgin Rail, and in part unhappy UK taxpayers about how the Virgin Group avoid paying UK tax... Both aspects are relatively hot issues at present.

For a more important story about what has the potential to be a *real* spaceplane:

Skylon/SABRE looks like a viable technology; I've just signed the UK gov e-petition for it to get some funding.

A few months ago, I posted an article about how NASA was recruiting cooks to prepare and test meals for a six-month flight to Mars. Here's a follow-up article:

Hmn, what's this?

.....months ago.....NASA cooks.....six-month flight to Mars.....Marian menu.....

Should be worth looking into.

Yeah, that was pretty cool. Thanks. for linking. I have to wonder why they think you can't preserve meat products for three years? There's a little technology called "canning" which is pretty good for this sort of thing.

Sailor B,

I think the problems of food go something like this:
1) Cans take up a lot of space and are heavy, so not practical for a long trip. Most of the current space food is in thin packages with minimal weight and waste and freeze dried.
2) Most of the food is pre-prepared, and requires minimal heating or cooking (just add water). Power for microwaving or pressure cooking for boiling water might be an issue. Also, it takes a while to cook food, and I think the current thinking is that this takes away from all the other things astronauts need to perform (though maybe they SHOULD spend a lot of time cooking to avoid boredom).

So given that most food is pre-prepared and in thin packaging, I think the issue is pre-prepared food goes to mush after a few years.

Supposedly, once on Mars they can supplement their food with fresh stuff from hydroponics and can set up a kitchen for preparing meals. Of course, the trip back will then have really old food that came with them all the way from Earth, unless they can re-package stuff for the trip back.
