Ares V (CaLV) - status

Michael Bloxham · 2007-09-12 05:05:30

Thanks cIclops. Tell me, do you also happen to know the Trans-Mars mass of the latests Mars Rovers? I want to get an idea of the difference.

cIclops · 2007-09-12 05:17:16

Sure Tom, not from memory but from an Aug 2006 NASA document, the MSL flight system is given as 3.6 mT.

Michael Bloxham · 2007-09-12 05:20:47

53.2 tonne versus 3.6?

Hehe, thats almost ridiculous. I stand by my earlier comments ;-)

Thanks cIclops.

Future In Space Operations - 29 Sep 2007

The video animation shows a concept for an Ares V heavy-lift launch vehicle placing, in this case, an 8-meter monolithic telescope into an orbit around the second Sun-Earth libration point. The planned performance of the Ares V, one of the largest launch vehicles ever developed, will permit even larger deployed or assembled systems or launches of multiple telescopes of various kinds.

Finally, we include five papers published recently that consider aspects of future in-space operations to achieve multiple science goals during the extended period planned for lunar exploration

Ares V Launch Capability Enables Future Space Telescopes (PDF) - 26 Sep 2007

NASA’s Ares V cargo launch vehicle offers the potential to completely change the paradigm of future space science mission architectures. A major finding of the NASA Advanced Telescope and Observatory Capability Roadmap Study was that current launch vehicle mass and volume constraints severely limit future space science missions. And thus, that significant technology development is required to package increasingly larger collecting apertures into existing launch shrouds. The Ares V greatly relaxes these constraints. For example, while a Delta IV has the ability to launch approximate a 4.5 meter diameter payload with a mass of 13,000 kg to L2, the Ares V is projected to have the ability to launch an 8 to 12 meter diameter payload with a mass of 60,000 kg to L2 and 130,000 kg to Low Earth Orbit. This paper summarizes the Ares V payload launch capability and introduces how it might enable new classes of future space telescopes such as 6 to 8 meter class monolithic primary mirror observatories, 15 meter class segmented telescopes, 6 to 8 meter class x-ray telescopes or high-energy particle calorimeters.

And maybe "Brute Force" missions to orbit Mercury, instead of wasting all that time with multiple planetary encounters.

Latest specification - from Reference Payload Capabilities (PDF 2MB) - 1 Oct 2007

Note LEO payload is now 128.8 tons @ 222 kms (120 nmiles)

A good illustration of the enormous capacity of Ares V in both weight and volume!

Commodore · 2007-10-31 22:06:51

Just think about that. How much usable interior space would a Bigelow/Transhab module built to fit into a 12m shroud provide?

It would dwarf the ISS in one shot.

My research says that the one with the 12m shroud is too tall to fit through the VAB door. I think the height restriction is somewhere between 127 and 130 meters? Perhaps they are considering fitting the fairing cap post-VAB?

cIclops · 2007-11-15 07:21:30

Yep. Just under that graphic in the document it says the VAB doors are 122m high. Ares V will also sit on the mobile transporter!

gaetanomarano · 2007-11-16 09:22:38

about the measurement systems confusion... in the Ares-V specs NASA doesn't use "mT" for metric tons but "MT" that sounds as "MILLION TONS"...

Aerodynamics (LRC)
Integrated health management (AMES)
Liquid rocket systems and stage testing at sea level and altitude (SRC)
EDS orbital environment testing at Plum Brook (GRC)

Notes

o First test flight (Ares V-Y) shown in 2017

o ATP = Authorization To Proceed

Notes:

o EDS upper stage is now 10m diameter same as the core stage

o EDS has composite structure instead of Al-Li

o Extra "Loiter skirt" for EDS

o Slighter longer overall at 110m

All appears well for Ares. I definetely hope to hear more regarding the Ares I-X test as well as those smaller abort-launch tests preceeding it.

not so well for the Ares-5...

http://www.aviationweek.com/aw/generic/ … nnel=space

and the Ares 1-X test may show too much acceleration (in some points of the flight profile) to be NOT compatible with human flights (and not possible to solve due to the solid rockets' nature) that's why I've suggested to do the 1-X test NOW than lose a further year to know that it's a bad choice

From Ares V Overview (PDF 2MB) - 26 Feb 2008

Notes:

o TLI payload now 63.6 MT (down from 64.6)
o Payload shroud now 10m (up from 7.5m)
o Loiter reduced to 4 days from 14
o EDS propellant increased

(gaetanomarano, this is a pre phase A study concept, many more changes will happen as they optimize the vehicle for the requirements, which are also changing)

You're also the only person posting to that site which already lowers it's credentials there as your credentials here are already rock bottom space-spammer.

gaetanomarano · 2008-02-28 18:38:16

...space-spammer...

a space-spammer that always IS right...

just one example about the Ares-5

as reported by cIclops, the Loiter Time has been reduced from 14 to 4 days

that's possible since NASA has changed the order of launch from Ares-1 first to Ares-1 last to avoid the risk of a failures due to a "sum-of-delays":

http://www.ghostnasa.com/posts/016esaschanged.html

well, I've evidenced the problem TWO YEARS AGO in this article:

http://www.gaetanomarano.it/articles/004.html

and discussed in one of my first threads on the BAUT forum

then, maybe, the NASA engineers could have read my articles and posts since there was NO mention of this problem in the ESAS plan...

so, I hope that ALL "spammers" will write useful articles like me...

gaetanomarano - please, no more Texas sharpshooting, we all know the trick. For those of you who don't, this is done by shooting many times at a barn door, then drawing a target around a cluster of holes and telling everyone you are a sharpshooter.

gaetanomarano · 2008-02-29 03:00:06

Texas sharpshooting

according to the sitemeter log, my sharpshooter's website has received several hundreds visits from Texas... mainly from Houston...
