Prior to the U.S. Senate Commerce, Science and Transportation Committee โs approval of a NASA authorization bill directing the agency to build a heavy-lift rocket and a crew capsule capable of reaching the international space station by 2016, NASA Administrator Charles Bolden and his deputy Lori Garver privately warned the billโs chief architects that NASA couldnโt finish the proposed rocket sooner than 2020, the Orlando Sentinel reported July 22.
The paper attributes its account to three sources present at recent meetings Bolden and Garver had with Sens. Bill Nelson (D-Fla.) and Kay Bailey Hutchison (R-Texas).
The Senate bill recommends giving NASA $11 billion over the next three years to get started on the new space vehicles.
โWhen asked about the conversation, Nelson spokesman Dan McLaughlin said the NASA officials were responding to lower dollar figures than what Congress ultimately approved. NASA spokesman Michael Cabbage said it โwould not be appropriate to discuss private conversations between NASA and members of Congress.โ
โBut requiring the rapid construction of a new spacecraft was critical in securing widespread political support โ even if the billโs supporters knew it would be an uphill climb for an agency with a reputation for busting budgets and deadlines.
โโGetting to this point required so much hard work and many trade-offsโ said Hutchison when the compromise was unveiled last week. The new launch system, she added, would โchallenge the best minds at NASA to develop a system on an aggressive schedule.โ
โUnder the compromise, NASA must build a rocket that could lift payloads of at least 70 tons, including astronauts, to the station, which orbits about 200 miles above Earth. It also must be designed so it could evolve into a bigger rocket with a lifting capacity of 130 tons or more that could eventually attempt missions beyond low Earth orbit, such as trips to nearby asteroids.
โAs an added requirement, NASA engineers must do all they can to incorporate pieces of both the shuttle, due to retire next year, and the now-defunct Constellation program. And in a nod to Utah legislators โ who represent the solid rocket motor company ATK โ the bill all but requires NASA to continue testing solid rocket motors, even if they are not guaranteed a place in the spacecraftโs final design.
โWith so many conditions, experts have raised doubts about the projectโs viability.โ
