Talk:Ares I/Lead

Overview: 1st paragraph

 * Ares I is the crew launch vehicle being developed by NASA as a component of Constellation Program.


 * The Ares name was chosen from the Greek deity Ares, who is identified with the Roman god Mars.


 * Ares I was originally known as the "Crew Launch Vehicle" or CLV.

Development: 2nd paragraph

 * Advanced Transportation System Studies & Exploration Systems Architecture Study


 * NASA selected the Ares designs for their anticipated overall safety, reliability and cost-effectiveness.


 * NASA completed the Ares I system requirements review in January 2007.

Role: 3rd paragraph

 * NASA plans to use Ares I to launch Orion, the spacecraft being designed for NASA human spaceflight missions after the Space Shuttle is retired in 2010.


 * Ares I is intended to complement the larger, unmanned Ares V, which is the cargo launch vehicle for Constellation.


 * Ares I has a payload capability in the 25 t class and is comparable to existing vehicles such as the Delta IV and the Atlas V.

Design: 4th paragraph

 * The first stage is a more powerful and reusable solid fuel rocket derived from the Space Shuttle Solid Rocket Booster (SRB).


 * Although its J-2X engine is derived from the engine used on the Saturn IB and Saturn V rockets, and the whole second stage is based on the internal structure of the Shuttle's External Tank, the upper stage itself is wholly new.


 * Igniter tests
 * I'm thinking that this whole section, in the article itself, should probably be worked into the "upper half" section... — V = I * R  (talk) 21:19, 18 August 2009 (UTC)

Proposed version
Ares I is the crew launch vehicle being developed by NASA as a component of Constellation Program. NASA plans to use Ares I to launch Orion, the spacecraft being designed for NASA human spaceflight missions after the Space Shuttle is retired in 2010. Ares I is intended to complement the larger, unmanned Ares V, which is the cargo launch vehicle for Constellation. NASA selected the Ares designs for their anticipated overall safety, reliability and cost-effectiveness.

The Ares name was chosen from the Greek deity Ares, who is identified with the Roman god Mars. Ares I was originally known as the "Crew Launch Vehicle" or CLV. The Ares I first stage is a more powerful and reusable solid fuel rocket derived from the Space Shuttle Solid Rocket Booster (SRB). Although its J-2X engine is derived from the engine used on the Saturn IB and Saturn V rockets, and the whole second stage is based on the internal structure of the Shuttle's External Tank, the upper stage itself is wholly new.
