Neil Armstrong urges return to the Moon

US astronauts Neil Armstrong and "Buzz" Aldrin deploy the US flag on the Moon in 1969. Astronaut Neil Armstrong has urged a return to the Moon to train for missions to Mars as the United States contemplates the future of its space programme following the end of the shuttle era.

Neil Armstrong has urged a return to the Moon to train for missions to Mars as the United States contemplates the future of its space programme following the end of the shuttle era.

The first man to walk on the Moon is due to address the on new directions for in coming weeks.

He has previously criticised US President for being "poorly advised" on space matters and said it was "well known to all that the American space programme is in some chaos at the present time, some disarray".

"There are multiple opinions on which goals should be the most important and the most pressing," he told a function in Sydney late Wednesday.

The US shuttle programme came to an end last month with the Atlantis cruising home for a final time, 42 years after Armstrong became the first person to set foot on the Moon as part of the .

Critics have assailed NASA for lacking focus, with no next-generation mission to replace the programme.

Now 81, Armstrong said the agency had become a "shuttlecock" for the "war of words" between the executive, legislative and congressional arms of US government.

"It’s my belief given time and careful thought and reasoning we will eventually reach the right goal, I just hope we do it fairly quickly," he said.

The normally private and reserved space veteran said should be the next frontier for exploration but urged more missions to the Moon as the vital next step.

US aviator and former astronaut Neil Armstrong, the first man to walk on the Moon, is due to address the US Congress on new directions for NASA in coming weeks.

"I do favour going to Mars but I believe it is both too difficult and too expensive with the technology we have available at the current time," he said.

"I favour returning to the Moon. We made six landings there and explored areas as small as a city lot and perhaps as large as a small town. That leaves us some 14 million square miles that we have not explored."

Armstrong said working on the Moon would allow scientists to practise "a lot of the things that you need to do when you are going further out in the solar system" while maintaining relatively close contact with Mission Control.

Communication is the major problem for trips to Mars, he added, with the relay of a message between Earth and the Red Planet delayed by about 20 minutes, compared with 1.5 seconds between here and the .

"Before you get an answer to your question almost an hour’s gone by, so it’s hard for Mission Control to be involved in a meaningful way helping you with that situation," he said.

"That's going to make a very difficult challenge for the early Mars missions to solve these kinds of delay sort of problems.

"I do believe that we will solve them in time, we’ll contrive a way to do that safely but we can't do it right now."

Travel time is also a major concern, with the quickest journey of two months only possible when Mars is closest to Earth -- when it also happens to be spinning most rapidly, meaning massive amounts of fuel are required to land.

"The best time to go to Mars is when it’s on the opposite side of the Sun to you, as far away as it can get, and that takes the least fuel, but it also takes about seven months one way, which is packing a lot of sandwiches," he said.

"And by the time you get there Earth has moved and it's no longer in a proper position to come back, so you have to wait around for a couple of years until Earth gets in the right position."

Armstrong said Mars was a "worthy challenge" but it was expensive, time-consuming and carried substantial risks not faced in the lunar programme, predominantly to do with radiation.

100% agreed!

Moon first, in order to: train crew members, test technologies, gather as much info as possible on long term term exposure and protection to radiations, how to build a ground base, etc.
Mars then.

Thank you Mr Armstrong for your lucidity and winsdom.
IMHO of course.

Moon first, in order to: train crew members

While the Moon may be an ideal testbed to train it's also a rather expensive one 'just for training purposes'.

People were trained to go to the Moon (which has more of a difference to Earth gravity than Mars does) quite successfully here on Earth - so don't think that argument counts much.

[qI favour returning to the Moon. We made six landings there and explored areas as small as a city lot and perhaps as large as a small town. That leaves us some 14 million square miles that we have not explored
As a percentage of area we have explored more of the moon than the ocean bottom. Maybe go there first? It would also be a good (and much cheaper) testbed for self contained biospheres/habitats.

When we get that problem down then we can send a (very small) biosphere to Mars orbit.

Mr. Armstrong, you waited over 40 years since you landed on the moon before you could be bothered to do the slightest thing in terms of space flight advocacy! And then you relate the most basic of facts about how hard it is to go to Mars. Do you really expect us to take you seriously? Lots of other people have been working the problem, sir, we've all shown you respect, you ought to return the favor!

"The best time to go to Mars is when its on the opposite side of the Sun to you, as far away as it can get, . . . "

This is wrong: a Hohmann transfer is not the best time to go to Mars. The trip time is not just a function of the least "fuel" (propellant), but an optimization of many factors, including the number of sandwiches to be packed.

Moon is a natural space station, it will help greatly to launch decent space crafts in space and get rid of the earth gravity/atmosphere pull.
Assembling on the moon is the only way we will be able to launch a decent spaceship to Mars in our current technology situation.
I am certain of it, IMHO of course.

Helium-3 is not the only raw material on the moon. There are deposits of radioactive elements like uranium. Also, digging into a non-tectonic and mostly cold surface is great. The first colony on the moon has a military advantage because of abundant resources as well as a smaller gravity well to escape.

Buzz Aldrin and Neil Armstrong should have a debate before congress, since they were both the first moonwalkers and are on opposite sides of the issue.
