Why was Ares V Cancelled?

Both rockets, deemed safer than the then-current Space Shuttle, would have employed technologies developed for the Apollo program, the Shuttle program, and the Delta IV EELV program. However, the Constellation program, including Ares V and Ares I was canceled in October 2010 by the NASA Authorization Act of 2010.

What happened to the Ares rocket?

canceled NASA rocket for project Constellation. Ares I was the crew launch vehicle that was being developed by NASA as part of the Constellation program. In September 2011, NASA detailed the Space Launch System as its new vehicle for human exploration beyond Earth’s orbit.

How many engines did Ares V have compared to SLS?

I see on Wikipedia that Ares V was to have had 5 Space Shuttle Main Engines compared to SLS’ 4, or 5-6 RS-68 engines which is what Delta IV uses. Is the fewer number of engines compensated for by extending the solid boosters for SLS? Is there any particular reason for the change in number of engines?

What is the difference between the SLS and SSMEs?

Main sustainer propulsion came from 5 SSMEs, while the upper stage was to use a single J-2X. A pair of 5-segment boosters would augment the stack. SLS is nearly identical, as it also features 8.4m core stage tankage to reuse shuttle tooling. In addition, the 5-segment boosters have been carried over.

How big was the Ares V rocket?

Ares V was, if it ever flew, to end up using the RS-68B, with even greater thrust and a newer ablative nozzle. The core also stretched to 71m in length, leading to a rocket capable of lifting 188t to LEO, 71t to TLI, standing 116m tall and weighing 3,705t on the pad.

How many boosters does the SLS have?

A pair of 5-segment boosters would augment the stack. SLS is nearly identical, as it also features 8.4m core stage tankage to reuse shuttle tooling. In addition, the 5-segment boosters have been carried over.
