- Lane, on 10/11/2007, -1/+15Sigh, I was hoping for a ThunderBirdish NASA super plane.
- Aesculapius, on 10/11/2007, -1/+12I am just disappointed by the lack of will to move to the next step of rocket development.
There is only so much energy density to be had from chemical rockets. We really need to be figuring out a way to utilize nuclear based propulsion safely. - KhanneaSuntzu, on 10/11/2007, -1/+12I'll fall on my knees and free provide oral sex on anyone who develops and manages a cost-viable launch system. I'd go as far as claim that the future of humanity depends on it.

- nyx210, on 10/11/2007, -1/+6I'd like to get that in writing, please.
- patm1987, on 10/11/2007, -0/+5Here's my trebuchet, where do you want to meet?
- jjb123, on 10/11/2007, -0/+4I am disappointed too, I wish more people were geeks or that we could get some geeks into the government.
- IamMikeMusic, on 10/11/2007, -0/+4Saturn V was the greatest rocket in history. No contest.
- inactive, on 10/11/2007, -0/+4First Manned Mission to Mars: Brought to you by Apple Inc.. This is an astronaut watching his videos on YouTube. This is him making a call, on his iPhone.
- anagoge, on 10/11/2007, -0/+3'scuse me?
- rheaume, on 10/11/2007, -2/+5He's a tard, worse than a republican, at least a right winger is willing to keep NASA, Education and others in the loop, RP just wants to nuke it all... for what? GIANT ***** TAX BREAKS. So I guess he's even more greedy than the average republican
- theNthDoctor, on 10/11/2007, -1/+4This is just more bla-bla-bla from the space program. IMO until rockets are laughed at and called quaint, it's all a waste of time. NASA should utterly scrap its mission timelines and devote 100% of it's efforts and funding on next generation propulsion.
- p51d007, on 10/11/2007, -0/+2As someone who went from diapers to computers with the space program, I for one will be GLAD when the shuttle is grounded for good! They put all their eggs in one basket with the shuttle, which was WAY behind schedule, WAY over budget and didn't deliver on its promises.
Rocket design was at its peak with the Saturn V program, and we just STOPPED. What a shame. - ljw5021, on 10/11/2007, -0/+1Buried, inaccurate. If you researched it, you'd know NASA already has a new prototype and design.
- starmanjones, on 10/11/2007, -0/+1i like the elevator myself. but we need rockets until we can harness dark energy or something. nuclear rockets are really not that dangerous. those cores can easily survive a catastrophic failure. when you consider the amount of crap the shuttle belches every launch... and huge payloads they can lift... the fact they can use about anything as fuel. i think rockets might be one of the few applications where nuclear is cost effective and safe.
- 0crabby0, on 10/11/2007, -0/+1"But the Ares I rocket and the Orion module won't be ready for launch until 2014."
It won't even be ready then... - Wasyu, on 10/11/2007, -0/+1Congress will not allow them to retire the shuttle until something has flown first.
One thing I don't get is why even build ares I it's just another medium payload launch vehicle we have delta IV heavy now which can launch LEO Orion missions by 2009 to 2011 for a lot less cost the only shuttle derived vehicles nasa needs are Ares IV and V as SDVs only make sense if you are going to lift very heavy objects like parts to a mars mission or an all up lunar mission.
Delta IV and falcon's BFR can do lunar missions since they can scale to 50tons and 70 tons respectively which is all you need for that.
Actually you could even do a moon mission using only 25tons class vehicles but the logistics gets messy and cryogenic stages don't like waiting on orbit though you could use storable propellants instead but these have terrible ISP which would require also building a solar or nuclear electric ion tug for moving the LEM and bulk cargo to L1 or lunar orbit before you perform a mission.
You would have to turn ISS into a depot and buy a few bigelow BA330s and make a depot station in L1 as
well though some people view this as an advantage since you're building an infrastructure. - toxicityj, on 10/11/2007, -0/+12 shuttles have blown up in the history of the shuttle. and both of the problems were discovered and fixed. and they've done several shuttle launches since the last explosion. That's far from "now will be grounded" status.
- IamMikeMusic, on 10/11/2007, -0/+1He makes it sound as though the private space groups will have their systems operational during the time between the space shuttle retirement and Ares I. It's not like NASA is going to retire their main vehicle before beginning design on the replacement.
- Wasyu, on 10/11/2007, -0/+1Actually nuclear rockets are not dangerous they were extensively tested during the 60s and 70s though high ISP most have radioactive exhaust so can only be used for upper stages.
A good use for a nuclear engine near term would be in the EDS since it would nearly double the payload ares V can send to the moon which would save nasa over 9 billion just on the moon base construction costs.
Also doing so will allow mars missions to be under taken concurrently nuclear isn't just a nice to have with manned Mars missions you need it it you don't go to mars since it cuts the mission time by half while sending twice the useful payload a similiar chemical only mission would send.
I favor axing the J2 development project and going with a nerva type engine for the EDS with a clustered RL60 stage for an interim stage if the nuclear stage runs into delays. - swordedge, on 10/11/2007, -0/+1There are plenty of non nuclear ideas that are less dangerous.
First, there is the nuke method where you build a space ship on a giant shield on really really good shocks. You toss a very small nuke behind it once every few seconds. This one is loonie
There is the space elevator. If you are willing to bankrupt the world trying to make a carbon nanotube cable 50K long, this is doable but loonie
Then there is the electromagnetic rail gun. Good for cargo. Use electricity to accelerate the cargo to escape velocity in five miles. if you rode it, we'd call you chunky soup as in 1000 G's of accel would leave little else
The one I favor, lasers. Pulsed at 250 or so times a second, 3 G accel out of atmosphere for a few tons every five minutes or so. Needs nuclear power stations to make go. - tbeseda, on 10/11/2007, -0/+1I know they thought about it. That was one of the original concepts. My dad is working on the project with Lockheed and his team was frustrated when they opted for an old-school capsule method.
- rheaume, on 10/11/2007, -0/+1Is the lander still made of foil?
- swordedge, on 10/11/2007, -0/+1Nasa has had many designs, nearly all canceled for stupid reasons. I will believe it when I see some hardware flying.
- drgruney, on 10/11/2007, -0/+1So I've got this plan... I'll get it constructed after you make good on your end of the deal.
- benlindelof, on 10/11/2007, -0/+1The space shuttle still is the World's Most Capable aircraft.
Good luck finding something as useful. - kestrel9, on 10/11/2007, -0/+0By objects, I did not mean craters and mountains. I meant buildings, bulldozers and things like that. If somebody builds it and pays at least part of the cost of sending it, then they own it.
- jtscira, on 10/11/2007, -2/+2The days where you can go from zero to putting a man on the moon in 20 years are gone. We should be ashamed of ourselves. Even our "new" aircraft look like the old airplanes with fancy electronics. The government bureaucracy and corporate greed has hampered true creativity. Good work !
Burt Rutan is god. - kestrel9, on 10/11/2007, -0/+0I like the idea of NASA dumping low Earth orbit altogether and concentrating on the moon. Private companies would own some of the objects on the moon, but the rockets should have a single owner -- NASA. NASA could give $1 billion to a company that wants to do something in low Earth orbit. It would be up to the company to figure out what it wants to do in low Earth orbit.
- Wasyu, on 10/11/2007, -0/+0Also it should be noted Soyuz has had two fatal accidents and two very close calls during it's history.
Soyuz wasn't completely safe until the late 70s with Soyuz T.
As for a savior for nasa I think COTS will be it's savior with most LEO missions being done by COTS spacecraft such as Spacex's Dragon, the RPK K1,the t/space CXV and planet space Silver dart etc.
Orion will mostly end up being used for deep space missions which is what it's intended for anyway.
Nasa might even decided to not build Ares I and just fly Ares IV or Jupiter which is really the only SDV booster they need .
Also launching Orion even LEO missions on a launch vehicle with a 70 to 100ton payload would allow ISS Orions to carry canceled ISS parts up as it would make a fairly good space tug even better then the ESA's ATV.
Another note the heavy shuttle derived vehicles if flown enough would actually cost less per Kg then even Russian and Chinese rockets since even though an Ares V costs about 500 million per launch for a max payload LEO mission though could cost as little as 270 million and it does carry 138,000 Kg which works out to around $3623 to $1957 per Kg.
Only the Falcon 9,Quickreach and Nova are cheaper.
As for the ESA they really should fund skylon for a long term project and ARD plus the ATV for a near term transport system. - joxer, on 10/11/2007, -0/+0umm...great except who said NASA has the right to 'sell' parts of space or the moon? Sure you could use the premise of first person there gets it, but then Russia (or USSR countries) would 'own' space around Earth and NASA could only have the moon. Although, come to think of it USSR also went to Venus, Mars and the Moon first with probes, so does that count?
- Wasyu, on 10/11/2007, -0/+0I think reaction engines skylon would be a suitable replacement for the shuttle.
As for Orion it could do many of the shuttle's missions if they ditch ares I and only build Direct launcher or ares IV and V.
Using just an HLV with Orion would save money over having to keep infrastructure for two very different vehicles.
Also going strait to the HLV launcher actually would cut 2 to 3 years off the development time since you could use a four segment srbs and existing RS68s and HL10 engines at first vs trying to resurrect the J2 which really doesn't have very good performance anyway it's ISP is only 430sec vs 455 to 470 for RL10 or RL60s. - rheaume, on 10/11/2007, -1/+1Constellation program sounds horrible, using old tech, no real breakthrough... Seemed just like something to take our minds off Iraq at the time, barely worked and now the reality is upon us, this is a half-baked clod war era type plan and Im not really digging it.

elevator shoes
Turn any shoes into height increase elevator shoes. - Wasyu, on 10/11/2007, -0/+0Yah the saturn V was a great vehicle but it was expensive though they had a good replacement on the books called Rombus before the shuttle program came about it was to be fully reusable and lift over 300tons.
Bringing back the saturn V now wouldn't make good economic sense instead building a large TSTO RLV type craft with a lox Kerosene first stage and a cryogenic orbiter stage would make the most sense now.
One of the big mistakes in constellation is bringing back the old J2 when a cluster of three RL60s would be cheaper could fly sooner and allow the EDS to be either 12% lighter or have 12% more payload.
Plus having three engines is safer then one if you loose one you can still perform the mission. - IamMikeMusic, on 10/11/2007, -0/+0Define "cost-viable".
- IamMikeMusic, on 10/11/2007, -0/+0Trust me when I say that there is a small amount of old technology being used in Constellation. Just because the crew capsule physically resembles Apollo on the outside doesn't mean that it's old technology.
- KriiBerg, on 10/11/2007, -1/+1well actually the nasa is kinda in big trouble the shuttles are blowing and now will be grounded and this program does not seem as a saviour of nasa. the only way we will ever reach the mars is if the us government does away with nasa china does away with cnsa, and Europe loses ESA and Roskosmos and they all band together and form a world space control (i would enjoy something like "terra nutus"for the name) plus there has to be a large degree of private money involved in this, because as the article points out the funding for the space programs is dependant on government policy and private fund involvement means long lasting contracts that would bind the governments into a steady stream of funding for these programs ending the program dependency of the good will of baboons a.k.a. politicians
- swordedge, on 10/11/2007, -1/+1I take it you have no idea that there are many in congress that would like nothing better then to kill nasa all together. They consider space adventures a colossal waste of money while using their GPS to not get lost and taking notes with pens developed for zero G. Not to mention all those computer chips. Space was one of the main drivers for them back in the day.
- choisum, on 10/11/2007, -0/+0Sounds great. This will open up many opportunity to investors.
