Where can I Download Ares for Free?

The Exploration Systems Architecture Study concluded that the cost and safety of the Ares was superior to that of either of the Evolved Expendable Launch Vehicle (EELVs). 7 The cost estimates in the study were based on the assumption that new launch pads would be needed for human-rated EELVs. 7 The facilities for the current EELVs (LC-37 for Delta IV, LC-41 for Atlas V) are in place and could be modified, but this may not have been the most cost effective solution as LC-37 is a contractor owned and operated (COGO) facility and modifications for the Delta IV H were determined to be similar to those required for Ares I.

12 The ESAS launch safety estimates for the Ares were based on the Space Shuttle, despite the differences, and included only launches after the post-Challenger Space Shuttle redesign. 13 The estimate counted each Shuttle launch as two safe launches of the Ares booster. The safety of the Atlas V and Delta IV was estimated from the failure rates of all Delta II, Atlas-Centaur, and Titan launches since 1992, although they are not similar designs.

In May 2009 the previously withheld appendices to the 2006 ESAS study were leaked, revealing a number of apparent flaws in the study, which gave safety exemptions to the selected Ares I design while using a model which penalized the EELV-based designs. Ares I was the crew launch component of the Constellation program. Originally named the "Crew Launch Vehicle" or CLV, the Ares name was chosen from the Greek deity Ares.

3 Unlike the Space Shuttle, where both crew and cargo were launched simultaneously on the same rocket, the plans for Project Constellation outlined having two separate launch vehicles, the Ares I and the Ares V, for crew and cargo, respectively. Having two separate launch vehicles allows for more specialized designs for the crew and heavy cargo launch rockets. The Ares I rocket was specifically being designed to launch the Orion Multi-Purpose Crew Vehicle.

Orion was intended as a crew capsule, similar in design to the Apollo program capsule, to transport astronauts to the International Space Station, the Moon, and eventually Mars. Ares I might have also delivered some (limited) resources to orbit, including supplies for the International Space Station or subsequent delivery to the planned lunar base. NASA selected Alliant Techsystems, the builder of the Space Shuttle Solid Rocket Boosters, as the prime contractor for the Ares I first stage.

1617 NASA announced that Rocketdyne would be the main subcontractor for the J-2X rocket engine on July 16, 2007. 18 NASA selected Boeing to provide and install the avionics for the Ares I rocket on December 12, 2007. On August 28, 2007 NASA awarded the Ares I Upper Stage manufacturing contract to Boeing.

Boeing built the S-IC stage of the Saturn V rocket at Michoud Assembly Facility in the 1960s. The upper stage of Ares I was to have been built at the NASA Michoud Assembly Facility, the construction site used for the Space Shuttle's External Tank and the Saturn V's S-IC first stage. At approximately US$20–25 million per engine, the Rocketdyne-designed and produced J-2X would have cost less than half as much as the more complex Space Shuttle Main Engine (around $55 million).

22 Unlike the Space Shuttle Main Engine, which was designed to start on the ground, the J-2X was designed from inception to be started in both mid-air and in near-vacuum.

No matter where you find it, any XP download you come across online is likely illegal. The only guaranteed legal course of action when you need a copy of Windows XP is to actually buy a new copy of Windows XP. It's that simple.

It's important to note as well that even if you did download Windows XP, what you would get is an image of the Windows XP Setup CD. For example, you would probably download an ISO file like windows-xp-pro. Iso, or something like that.

You would then burn that ISO image to a CD that you would then use to install Windows XP.
