" ... A year after the introduction of this [Asteroid Retrieval] mission, the Administration still has not provided a detailed mission profile or budget proposal. The Consolidated Appropriations Act of 2014 required NASA to provide additional details about the mission concept before Congress would commit long-term resources to the effort."
"The President's budget again seeks to fund an Asteroid Retrieval Mission (ARM), a mission that experts and Congress have sharply criticized. Chairman Lamar Smith (R-Texas) highlighted testimony before the Committee by NASA Advisory Council Chairman, Dr. Steve Squyres, who said "I see no obvious connection between [ARM] and any of the technologies or capabilities that are required for Martian exploration."
"The Asteroid Redirect Mission (ARM) will enable NASA to test powerful Solar Electric Propulsion (SEP) and integrated human/robotic vehicle operations in deep-space trajectories. Like the invaluable ISS, this mission will provide NASA with critical knowledge, experience and technologies for future human exploration missions deeper into space."
"During her questions to General Bolden later in the hearing, Ms. Edwards emphasized the need for the Subcommittee to obtain a roadmap for a human mission to the surface of Mars accompanied by the analysis of the options for potential interim destinations."
