A better style of spacesuite has been shown on TV through Star Trek - First Contact. Sometimes designer of real life uses should look more closely to Scifi technologies.

See yourself >

better helmet structure, and could use the Boeing electronic blind system through the glass to build an electronic face shield.

Those were dam nice costumes.

I suppose if we can pull off the Richard Simmons space suit, then those should be easy.

They recently found a large reservoir of frozen water on the moon. It could be melted via solar energy and turned into water to mix with concrete.

Yeah the trouble is there isn't water in the quanitys that there are on Earth. The water on the moon is better used for human comsumption.

Why make concrete when we can melt the various metals into solid  peices, or melt the silicates into huge hulks of solid, though dirty, glass.

It could be the cure for aids or it could be what wipes out the planet. It should be studied on the Moon or in a lab in orbit first.

It would be a sad twist of fate for us to finally find alien mircobial life, only to have it wipe us out.

If everyone else is going to launch from there, and put stuff in an  orbit ideal for that launch site, can we afford not to?

If other countires decide to build a space station in an equatorial orbit, then the US would simply not be able to contribute any launch services.  However, the US has enough power and influence that it could probably bully any group that it is part of into using a 28 degree orbit.

Probably, but for commercial purposes, the ESA and now Russia will be able to launch either bigger payloads for the same price, or the same payload for less.

I'm thinking it would be worth the billions in the long run to use the Vision as an excuse to build our pads on prime real estate, with the  the big launchers picking up the better part of the tab, and in return they can use our pads there to compete with the other two.

#931 Re: Interplanetary transportation » Magnetized-beam plasma propulsion - 90 day Mars round trip? » 2004-10-20 16:19:54

An interesting idea.

But what if the beam misses, and hits something else? Something important?

Whatever happens in the heavy lift department, the Russians seem convinced there going to have a pad in French Guiana.

http://en.rian.ru/rian/index.cfm?prd_id … o_alert=0] TEST LAUNCH OF NEW CARRIER SOYUZ 2 MIGHT BE POSTPONED - EXPERT

MOSCOW, October 20 (RIA Novosti) - The first test launch of the new Russian Soyuz 2-1A carrier rocket from the Plesetsk Space Center is highly likely to be postponed for several days because of ground systems failure, a competent source working on the launch program told RIA Novosti on Wednesday.

"According to preliminary data, the first launch of the new Soyuz, previously scheduled for October 29, will be postponed for several days, to November 2 - November 5," he said.

According to the source, postponement of the launch date is nothing extraordinary.

"It is always extremely difficult to prepare for the first launch, for it attracts much attention, and it's better to check everything once again than fail in the end," the source said.

Previously senior engineer with the Progress design bureau Valery Abrashkin told RIA Novosti that the first experimental task for the Soyuz 2-1A would be to orbit the Oblik Russian spacecraft.

"In fact, this satellite, with its service life expired because it was built many years ago and has since been not launched for financial reasons, is just a mock-up of payload," Abrashkin said.

However, according to the engineer, the Oblik will be equipped with all necessary testing devices.

"The spacecraft has modern vibration and temperature sensors to check the operation of the first- and second-stage modernized engines," the engineer said.

The first vehicle of the new Soyuz generation also has a large four-meter fairing that enables the rocket to take 300kg of additional payload.

"New Soyuzes will take to the outer space from the new launching pad our people will build at the Kourou space center in French Guiana. As soon as we have a record of several successful launches from our pads and enough statistical data, we will move the Soyuzes to the Guiana site," Abrashkin said.

If everyone else is going to launch from there, and put stuff in an  orbit ideal for that launch site, can we afford not to?

Russia must be getting desperate to ask a foot, gallon, slug measuring country.

Slugs?  ???

RUSSIA PROPOSES TO U.S. PARTICIPATION IN SUPERHEAVY BOOSTERS LAUNCH PROJECT

MOSCOW, October 18 (RIA Novosti) - During visit to Baikonur of NASA Deputy Administrator Frederick D.Gregory, the Russian side proposed the United States' participation in the unique project Spaceport (Kosmoport), which intends the launch of superheavy carrier rockets, Vyacheslav Davidenko, official spokesman for the Russian Space Agency, has told RIA Novosti on Monday.

"Fred Gregory and a representative delegation of American scientists and businessmen inspected the versatile complex Stand-Start, designed for testing and launch of Energia carrier rockets under the programme for the reusable space system Energia-Buran. The first start was made on May 15, 1987", he said.

During the talk on the programme, the Stand-Start performances and its unique capability to launch superheavy boosters, the American side was proposed to participate in the Spaceport project, Davidenko said.

"Spaceport could breathe a new life into the facility and rid future participants in international cooperation of heavy investments to be made in a new space infrastructure. It is already in place here and only has to be adapted to new projects", he said.

In the future, Spaceport can provide an opportunity for launching superheavy carrier rockets for interplanetary missions and exploration of planets in the Solar System.

"It will be, certainly, the large-scale project of a manned mission to Mars, building of a space base on the Moon", Davidenko said.

"The American delegation discussed the proposals for a long time and chief delegate Fred Gregory has promised to continue cooperation with the Russian side after reporting to NASA chief Sean O'Keefe", Davidenko added.

To him, Russia is going to propose participation to other space powers, too.

I like the Energia platform, but I think if were going to all work together in this, then Kazahstan is not the best place to launch from. It's better to get the ESA to let us build a couple launch pads in there facility in the South Atlantic.

And I think that even if we do go with the Energia, be should still develope an alternetive in the event that something goes wrong, we don't end up stranding people somewhere.

Russia to Built New Orbital Platform
10/14/2004 15:20

Roskosmos chief Anatoly Perminov said at the International Space Congress in Vancouver that according to Russia's federal space program for 2006-2015, Russia is going to develop a new orbital basic platform available for cosmonauts.

Roskosmos cited Anatoly Perminov as saying that this platform will let continue and increase the researches currently conducted at the International Space Station. He adds, the new platform will combine the advantages of a manned complex and an unmanned space vehicle.

The Roskosmos chief said the new orbital platform "is particularly meant for development and tests of perspective interplanetary complexes and for testing the complex of new generation transport and hardware systems." The Roskosmos release reports that the complex will include a reusable system for orbiting freight and new braking mechanisms for freight delivery to the Earth and to planets.

Anatoly Perminov believes that assembly and launching of a manned complex to Moon and Mars must be done on the orbit. This in its turn requires creation of an assembly platform and an effective system to provide assembly operations with transport and hardware.

The Roskosmos chief reports Russian space research institutes and industrial companies have been working on the problem since 1960-70s. "Russia has a large scientific and technical reserve essential for such a global project," Anatoly Perminov says. For instance, various aspects of a Martian expedition are worked on now: organization of the expedition, flight routs, projects of an interplanetary complex, training and medical care of space crews, life-support systems and so on.

Russia is also experienced in organization of long manned flights. The Russian methods for selecting and training of cosmonauts, the effective medical care during space flights save health and efficiency of space crews.

However, Anatoly Perminov adds the interplanetary manned expedition demands joint efforts of countries with leading space technologies and great achievements. This is important for technical maintaining as well as for financial support of the project. The exact date of the project implementation depends upon several factors such as the scope on international cooperation, its technological, industrial and financial reserves, Anatoly Perminov concluded.

Throughs?

I think that there on the right track, though I hope that if there going to do it they'd compare notes with us. I also wonder were there going to get the money.

Also, is this the final nail in the ISS cofin? Were pulling out when its done, and I doubt the Russians will have the money to support that and build and support this.

#938 Re: Human missions » Funding space - How much do Americans pay for sneakers? » 2004-10-13 17:56:00

I wonder why NASA doesn't sell advertising?  There must be some law that prevents them from doing it.  Just think of what a Victoria's Secret add would look like as it blasted off from the Cape.

Hell, can you imagine how much the people at Trojan would pay to have there icon on a rocket?  big_smile

#939 Re: Human missions » Funding space - How much do Americans pay for sneakers? » 2004-10-13 16:56:28

Unfortunatly, if astronauts got sneaker contracts, it would be viewed as goverment brainwashing.  :bars2:

#940 Re: Science, Technology, and Astronomy » HOPE Mission to Callisto - Proposal for Manned Mission to Jupiter » 2004-10-12 19:40:50

Thats one of the targets for Jupiter Icy Moons orbiter isn't it?

Don't get me wrong, but for that time period, arn't there better targets for an outer solar system mission? Like say Europa, or Titan?

Edit: Now that I mustered the bandwith to download and read it, I see the point. But it still seems pointless to land on Callisto to run a sub on Europa. Theres tons of ice there which is the best radiation shield out there, which will be despirately needed in the Jupiter system. And given the amount of hardware were going to have to land on Europa anyway, contamination is inevitable.

Oh and is there supose to be videos in that PDF?

#941 Re: Human missions » Long duration Human space missions - Can we survive them? » 2004-10-12 16:18:11

Sorry, but group dynamics can be affected by certain human equations. We can artificaly expect everyone to be adults, or we can be realistic and consider the very real chance of problems resulting from certain combinations of crew members. It would be unwise to have blacks or jews if we were sending racists or neo-nazi's. You can see that, right?

Thats right. They have to either be all Yankees fans, or Red Soxs fans.  big_smile

#942 Re: Planetary transportation » Navigating on Mars » 2004-10-11 17:26:45

Whenever I talk about humans on mars it's only as far as the mars direct plan.  Others here want massive human populations on mars from the first landing.  So launching many GPS satellites for mars is not necessary in my opinion while others think it is a necessary first step.

I wouldn't assume massive populations, but I would assume coutinuous habitation, continous operations, and cycling of crews. It would help landers as well.

But thats why I'd imbed it into a series of multipurpose orbiters, the other data gathered more than justifies the cost, and the infrastructure will be there when were ready for it.

#943 Re: Planetary transportation » Nuclear Transportation? » 2004-10-11 16:47:40

Has anyone considered a blimp?

It can go places (or deposit people) were a rover can't go. The power required to move around would be considerably less, and could be augmented by putting solar panels on top.

#944 Re: Planetary transportation » Navigating on Mars » 2004-10-11 15:44:33

Considering that Mars is one third the size of Earth, I can't imagine we would need a constellation of 24 satillites to get the job done.

I'd suggest a smaller constellation of about 12 multipurpose GPS/Communications/Weather/Opical satillites.

#945 Re: Human missions » Long duration Human space missions - Can we survive them? » 2004-10-11 15:33:28

Anticarrot: you sure NASA would send a mixed crew the first time? I seriously doubt that...

Can you imagine the feminist uproar if they didn't?  big_smile

I guess that means we'll have to have the token black guy too. Wearing a red shirt.... big_smile

#947 Re: Human missions » Kerry's position on space *2* - ...continue discussion here (for now) » 2004-10-11 15:22:57

Who here really thinks that were anyweres near ready to start throwing large sums of money at this?

Were doing exactly what we should be doing, exploratory studies to figure out the best way before we throw money at it, and handing out technology grants to help towards that effort.

#948 Re: Human missions » Kerry's position on space *2* - ...continue discussion here (for now) » 2004-10-09 11:49:49

That said, yes the CEV will cost quite a bit if we do it right, but I think it can perform as advertised after we shake the bugs out. The technology is simply not that difficult, much of it will be on hand by then... heat shield, parachutes, docking guidence (DART demonstrator), escape motors (Lockheed's PADD), OMS engines (X-37 derived?), all that will be done before the CEV project even begins in earnest. I think it can perform the same function as the Apollo CSM and perhaps become an "American Progress" light cargo hauler too without costing more then $100-150M-ish per copy.

I really don't see the CEV as being that expensive if we keep our expectations reasonable. Its a quick, reusable people/light cargo hauler.  It doesn't need to be any more than a Command Modual II for 6-8 people. If we want a service modual, send up a permenent inflatable and dock with it. Anything else we want to use can dock with it too.

It appears that bone loss will soon be a thing of the past if all goes right. Article has lots of details into how fast and what percentage. Inaddition talks of what else are issues as seem with long duration flights in reduced to 0g levels.

Drug may keep astronauts' bones strong
Annual injection could allow prolonged space missions.

It's a start, but they lose muscle mass as well, which is just as important.

The only caveat is that during 1/3 of the year, crop yields will fall because of dust storms (during thick global dust storms, insolation drops considerably).
