In May 2010 NASA planned flight demonstrations of Ares V hardware along with Ares I hardware after the scheduled upcoming Ares I-X Prime test of the Ares I 5-segment SRB first stage. Several flights were listed as "Heavy Lift" test flights for testing the first stage of the Ares V simultaneously with the Ares I upper stage attached on top of the Ares V first stage. This would save both time and money in avoiding the gap between testing Ares I and Ares V hardware with current limited funding.

Design

The Ares V was intended as a heavy-launch vehicle to send large hardware and materials to the Moon, or to send supplies beyond Earth orbit to sustain human presence there. The Ares V was designed to be a three-stage rocket: the first and second stages, which burn together, were to utilize both solid and liquid propulsion with the upper stage providing the necessary propulsion to send the hardware and staples beyond low-Earth orbit and onto a trajectory to the Moon.

The EDS was to be used to steer the Altair lunar lander into its initial low-Earth "parking" orbit for later retrieval by the Orion spacecraft, and then would propel both the Altair and Orion to the Moon. The EDS could also have been used to haul large payloads into low-Earth orbit, along with placing large unmanned spacecraft onto trajectories beyond the Earth-Moon system.

The Ares V was designed to have a payload capacity of over 414,000 lb (188 metric tons) to Low Earth orbit

s, and the liquid-fueled upper stage from the Ares I, as described by NASA in January 2007. The Ares IV would be a combined 113 m (370.7 ft) tall and could be used to reach the Moon. Total payload capacity would be 41100 kg (90,610 lb) to 240 miles (386 km) for direct trans-lunar injection.

NASA was considered using Ares IV to evaluate high-speed "skip" reentry profiles of the Orion capsule in 2007. NASA had planned flight demonstrations of Ares I and Ares V hardware in "Heavy Lift" configurations from 2013. The "Heavy Lift" test flights were to test the first stage of the Ares V simultaneously with the Ares I upper stage attached on top to save both time and money. The later Heavy Lift test vehicle configurations are similar to the Ares IV vehicle.
