In January 2004, President George W. Bush introduced the imaginative and prescient for area Exploration (VSE), which prompt NASA to 'Extend human presence around the sunlight procedure, beginning with a human go back to the Moon via the yr 2020, in instruction for human exploration of Mars and different destinations,' between different pursuits. As stated within the VSE, major expertise improvement should be essential to accomplish the targets it articulates.NASA's Exploration expertise improvement application (ETDP) is designed to help, increase, and eventually give you the invaluable applied sciences to fulfill the pursuits of the VSE. This ebook, a evaluation of the ETDP, is extensively supportive of the reason and pursuits of the VSE, and reveals the ETDP is making growth in the direction of the said pursuits of expertise improvement. even if, the ETDP is working inside of major constraints which restrict its skill to effectively accomplish these pursuits - the nonetheless dynamic nature of the Constellation software specifications, the restrictions imposed through a constrained funds, the competitive time scale of early know-how deliverables, and the need to completely hire the NASA staff.

Sample text

An example of industry capability is Al-Li structures and welding. In addition, industry has demonstrated large friction stir weld-spun domes that are very close to the Ares I requirements. The alloy Ti Al Beta 21 S is currently being used by industry and is not being considered by NASA in the VSE program. The project group itself identified some existing manufacturing techniques not being used by NASA owing to licensing issues rather than technology development issues. It also appears that a lack of specific requirements in some cases has allowed in-house projects to float goals and produce simplistic measures of success.

32 A CONSTRAINED SPACE EXPLORATION TECHNOLOGY PROGRAM Alignment with the Vision for Space Exploration: Green Flag The benefit of this project to both lunar and Mars exploration is well aligned with the goals of the VSE. These technological advances, given the virtual guarantee that mission software will increase in complexity and requirements for reliability, will all be enabling for a Mars mission as well as the lunar mission. 12 AUTONOMOUS LANDING AND HAZARD AVOIDANCE TECHNOLOGY Objective The primary objective of the Autonomous Landing and Hazard Avoidance Technology (ALHAT) project is to develop and mature various hardware and software components that will aid lunar descent vehicles.

The technical approaches are solid, if somewhat limited. A good assessment has been made of what is required for the maturation of ISHM tech­nologies such that actual mission program insertion can occur. Effectiveness in Developing and Transitioning: Yellow Flag There was no clear visibility for the roadmap and risks associated with the ISHM effort to expand and enhance the limited scope of developments underway to include the addition of new systems and subsystems. This seems, in part, a result of what appears to the committee to be limited buy-in from the customer, despite significant performance parameters assigned to this project for risk reduction in Constellation.
