Ares V Rocket Gets an Upgrade: It will be Bigger and Stronger for 2020 Moon Mission (Video)
Written by Ian O'Neill
NASA announced on Wednesday that the original Constellation project's principle rocket, the Ares V, will need to be designed to carry a larger payload for manned missions to the Moon by the year 2020. This means the original concept will need to have a length extension of 20 feet (6 metres) and will need to use six main engines at its base, rather than the current five. This upgrade will be capable of sending far more instrumentation into space, an extra 15,600 lb (7,000 kg, or the equivalent mass of a male African elephant)…
When the Shuttle is retired in 2010, there is going to be a five-year gap before the Constellation Program prepares its first Ares launch. There can therefore be little room for setbacks in the design phase of the Ares rocket system as there are already concerns for the US dependence on Russia to provide access to space between 2010 and 2015.
In a move to make the heavy-lift vehicle more robust (predicting an increased launch thrust requirement) to send four astronauts, a lunar lander plus supplies, NASA has announced the Ares V rocket will be "beefed up" to cater for our future needs to get man back to the Moon. This huge vehicle is now designed to carry payloads of over 156,600 lb (71,000 kg), some 15,600 lb (or 10%) more than the original concept. Ares V was originally designed to be approximately the same length as the original Saturn V lunar rocket (361 feet or 110 metres long), but to accommodate an extra booster engine and extra payload volume, Ares V will be 381 feet (116 metres) long. That's the height of a 38-story building. This increased capability will obviously be of huge benefit to the future lunar and Mars missions.
These design alterations were announced after a nine-month study to investigate whether NASA could succeed in its goal to be ready for a return mission to the Moon in 2020, and a manned mission to Mars afterwards. Constellation program manager Jeff Hanley is upbeat about the study's findings. "This extensive review proves we are ready for the next phase: taking these concepts and moving forward," he said.
The Constellation Program will use a two-step method for getting man and machine into space. The Ares V will launch heavy payloads, using its superior power, whilst the smaller Ares I will be used as a general low-mass/manned transit vehicle. For large missions, both Ares V and Ares I launch vehicles will be used, allowing astronauts to dock with their equipment in space before travelling to the Moon and beyond.
All I know is, whether Constellation is completed on time or not, I'll be at the launch to watch the awesome Ares V lift off from Cape Canaveral…

Why isn't NASA considering using the Ares V to launch both the Orion, the lander, and Earth Departure Stage?

Ugh…shouldn't have that "both" in there.

I will travel to America just to watch one of these launch. Awesome!

I'll meet you there! Seeing a Saturn V or the Shuttle launch must be the most incredible experiences I can imagine. I want to see Ares V's first launch. Something to tell the grandkids
Launch party I think, might start planning one now!
Cheers, Ian

I think they are trying to split off the missions by splitting the rockets.
They need a cheap and safe low earth orbit ferry.
So you have a tricked out capsule with solid rocket booster.
They need a heavy lift rocket for lobbing payloads.
So you also have an autonomous cargo ship.
Theres no need to travel with your cargo on the way up from the surface, so long as you can meet it in space. So it would safe cost on the payload rocket while not making the astronauts ride any more dangerous.
The last part is making it capable of a ground landing so you can save money on the recovery.

Larger is not necessarily better. Smaller is more economical, practical and safer. If a vehicle is lost, the negative impact on the project will be lessened. Too many "eggs in one basket" is risky!

I wonder if the 71000kg payload are to LEO or the Moon?
And what about the payload dimensions and volume?
Does anyone know?

Ian, Astrofiend -
I'll be there, as well.

ATTENTION: To the reader
To keep the two of the next alluded the more valued by the HUMANITY, it becomes of an question of cost effectivity considered so to continue to allow man's investigation of the outer reaches of SPACE.
Non-disputively; it is of an importance to find out about and to learn about the reaches of space and to do this it is of an importance to transfer into space the men, the women, the necessary equipment and the needed amount of the supplies transported into space…but the cost effectivity of this project must needs be considered so to make more profitable and valuable the directions of the space exploration and colonization.
Futuristically alluding; it is discoverable the means of the use of the FATHER GODDARD'S ROCKETRYS means of the transport of the physical pay-load transferred into space a primitive means and a costly thing: the FATHER GODDARD'S means of the rocketry used to transport of the physical payload directionally and distentially transferred into space; it is not, at all, a cost effective means to transport, into space, men and property transported, deep, into space; but rather the use of some other and of different means more cost effective is required, for use, to transfer payloads more cost effectively transferred, deep, into the reaches of space, and to this end it becomes necessary to make of an use of the interaction of the most elementary of the, other-wise, natural forces, controllably, interactional had, of nature itself, made of an use so then to make more cost-effective the instantaneous means of the physical pay-load transported deep and controllably transported into the reaches of outer space then accomplished of a more cost effective means, of an instantaneous means, and of the needed numbers of the PHYSICAL PAYLOADS transferred, instantaneously and controllably as transferred into the father-most reaches of space: to do this, it is required of an use of a new kind of the science and technology innovated what can be made of an more cost-effective means made of an use so to be allowed more profitablyi to do of it of an instaneous means.
That this to allude: it is possible to perform of an instantaneous means of it's elements made of an use what men must needs learn about to make of an use of the new kinds of the phenomenal and or physical "things" made of an use so to be allowed to accomplish of this accomplished of an intricacies of an use of the new kinds of the phenomenal, physical and or of an controllable means made of an use so to be allowed to do of it accomplishable of a different, of a more cost-effective and of an instantaneous means!

…must still be some good drugs up there in Madison…sounds like someone's nearly in space already!
June 27th, 2008 at 9:03 pm
Seriously, I sure hope I get to see one of these go up someday. I have always wished I could have watched a Saturn V launch in person, and this sounds even bigger/better!
June 29th, 2008 at 3:45 am
I hope that by launch time I have the funds to travel and see it launch. It is quite a sight. I've seen them launch small satalite rockets here in California and it's beautiful even from 400 miles away. It creates a nice blue trail as it leaves. Quite a sight.

"Constellation project's principle rocket, the Ares V"
Shouldn't that be princiPAL rather than princiPLE?
June 29th, 2008 at 7:58 pm
Apollo 17 was the only night launch of a Saturn V rocket. It was described by all who witnessed it as a second sun-rise. The Ares V will be larger; I hope someday to witness another night launch as spectacular as that.
June 29th, 2008 at 11:26 pm
I wonder if they're "sneaking" in the requirements upgrade to be able to more easily support a manned asteroid mission.
Quite a few friends in the space industry anticipate that the moon mission will be scrubbed in favor of going somewhere new with more direct applicability towards Mars.

Why in the age of Miniaturisation , carbon fibre - micro electronics , micro motors and machinery, kevlar , lightweight titanium and aluminum alloys etc and such do NASA need to make the rocket bigger !
They should be making everything smaller - even the astronauts should be smaller (serious) ! send people who weigh 45-75Kg instead of 90-120Kg when you add in the support equipment - oxygen, food ,maximum weight ratings it becomes very significant.
You can make a light weight moon rover vehicle , smaller lighter parts,Smaller but stronger capsules, design everything smaller and lighter with bigger safety margins , extra fuel , and ultimatly achieve more with less !.

They should have been taking off from a runway by now..
