NEWS January 4, 2017 (source: NASA)

NASA has selected two missions that have the potential to open new windows on one of the earliest eras in the history of our solar system--a time less than 10 million years after the birth of our sun. The missions, known as Lucy and Psyche, were chosen from five finalists and will proceed to mission formulation, with the goal of launching in 2021 and 2023, respectively.

Psyche @ Metal World

In Formulation

Psyche will spend 20 months orbiting 16 Psyche in four different orbital periods.

New Frontier Program . Discovery Program . About ANNOUNCEMENT OF OPPORTUNITY 


When NASA Give an ANNOUNCEMENT OF OPPORTUNITY (AO)- example, for the DISCOVERY PROGRAM (or the New Frontiers Program) - number: NNH14ZDA014O
NASA issues this AO for the purpose of soliciting proposals for investigations to be implemented through its Discovery Program. All investigations proposed must support the goals and objectives of the Program, must be implemented by Principal Investigator (PI) led investigation teams and through the provision of complete spaceflight missions.
Proposed investigations are evaluated and selected through a two-step competitive process.
Step-1 is the solicitation, submission, evaluation, and selection of proposals prepared in response to this AO. As the outcome of Step-1, NASA intends to select multiple Step-1 proposals and issue awards (provide funding to NASA Centers and the Jet Propulsion Laboratory (JPL), award contracts to non-NASA institutions, or utilize other funding vehicles as applicable) to the selected proposers to conduct Phase A concept studies and submit Concept Study Reports to NASA.
Step-2 is the preparation, submission, evaluation, and continuation decision (downselection) of the Concept Study Reports. As the outcome of Step-2, NASA intends to continue one or more investigation(s) into the subsequent phases of mission development for flight and operations.
NASA recognizes and supports the benefits of having diverse and inclusive scientific, engineering, and technology communities and fully expects that such values will be reflected in the composition of all proposal teams as well as peer review panels (science, engineering, and technology), science definition teams, and mission and instrument teams.


Proposals selected are implemented in accordance with NASA mission management processes. These latter processes, defined by NASA Procedural Requirements (NPR) 7120.5E), the NASA Space Flight Program and the Project Management Requirements are Formulation, Approval, Implementation, and Evaluation.
So, in the NASA mission management processes, we have the Formulation divided in Phase A – Mission Concept and Requirements Definition and Technology Development; and Phase B – Preliminary Design and Technology Completion.
If Approved, that means we have the Confirmation process for transitioning into Implementationdivided into Phase C – Final Design and Fabrication; Phase D – System Assembly, Integration and Test, and Launch (extending through in-space checkout); Phase E – Operations and Sustainment; and Phase F – Closeout.
Evaluation is the ongoing independent review and assessment of the project’s status during both Formulation and Implementation as described in NPR 7120.5E, which may be found in the Program Library.
BUT, in the NPR7120.5E document, we have defined a Key Decision Point (KDP) that occurs before the project is approved to begin the next phase of development.
For missions selected, KDP-A is the selection of a Step-1 proposal for a Phase A concept study, KDP-B is the downselection of a mission to enter Phase B following evaluation of Concept Study Reports, KDP-C is the culmination of the Confirmation process, KDP-D is a transition that occurs after the Systems Integration Review, KDP-E is the handoff from development to operations, and KDP-F is the decision to terminate operations after completion of the mission. Scientific and other analyses, including data analysis and preliminary analysis of returned samples, may continue under project funding in Phase F. If the decision at downselection is to maintain the selected investigation in an extended Phase A, then a separate KDP-B will be required.


Any alteration of a mission that renders it unable to accomplish one or more of its baseline science objectives will be regarded as a descope of the investigation. NASA will review any such descoped set of achievable science objectives to ensure that the investigation remains at or above the Threshold Science Mission. A descope made necessary by the PI's inability to remain within budget or schedule, or failure at any time during formulation and implementation to maintain a level of science return at or above the Threshold Science Mission, can result in mission cancellation accompanied by appropriate contract action, which may involve termination.
During Phase A, each selected PI will conduct a concept study. The Phase A Concept Study Report must include a commitment by the PI for the PI-Managed Mission Cost, schedule, and scientific performance of the investigation. If, at any time, the cost, schedule, or scientific performance commitments made in the Phase A Concept Study Report appear to be in peril, the investigation will be subject to termination or cancellation.
During Phase B, each selected PI will work with NASA to develop top-level science and technical performance requirements. Each PI will also work with NASA to establish a set of performance metrics for project evaluation. These will include cost, schedule, and others, as appropriate.
Once an investigation has been confirmed for implementation, failure of the PI to maintain reasonable progress within committed schedule and cost, and/or failure to operate within other applicable constraints, may be cause for NASA to convene a termination review. The Associate Administrator (AA) for the Science Mission Directorate may also call for a termination review any time an excursion above the agreed upon mission cost in Phase C through Phase E occurs, or is projected to occur, by the PI, the implementing organization, or NASA.
The objective of such a review is to determine whether remedial actions, including changes in management structure and/or Key Management Team members, would better enable the project to operate within established cost, schedule, and/or technical constraints. If a termination review determines that no remedy is likely to improve matters, NASA may consider mission cancellation and/or contract termination. NASA may cancel a mission and/or terminate a contract notwithstanding any international or domestic partnerships established to enable the mission.

Discovery Program Goals and Objectives

The goal of NASA’s Discovery Program is to provide frequent flight opportunities for high quality, high value, focused, planetary science investigations that can be accomplished under a not-to-exceed cost cap.
By conducting a series of planetary science investigations, NASA will provide a mechanism by which pressing questions in planetary science may be addressed, permitting a steady improvement in our understanding of planetary systems and the processes that affect them. The frequent, steady nature of the investigations will ensure a continuing stream of fresh scientific data to the planetary science community, thus helping to maintain the excellence of the U.S. planetary science program and to inspire the next generation of investigators.
The Discovery Program strives to:
  • advance scientific knowledge and exploration of the elements of our Solar System;
  • add scientific data, maps, and other products to the Planetary Data System archive for all scientists to access;
  • announce scientific progress and results in the peer-reviewed literature, popular media, scholastic curricula, and materials that can be used to inspire and motivate students to pursue careers in science, technology, engineering, and mathematics;
  • expand the pool of well-qualified Principal Investigators and Program Managers for implementation of future missions in Discovery and other programs, through current involvement as Co-Investigators and other team members; and
  • implement technology advancements proven in related programs.
These goals and objectives are also articulated in the Discovery Program Plan, which can be found in the Program Library.
The Discovery Program was initiated in 1992 as a way to ensure frequent access to space for planetary science investigations. Previous Discovery Program AOs were released in 1994, 1996, 1998, 2000, 2004, 2006, and 2010. The completed missions in the Discovery Program are NEAR, Mars Pathfinder, Lunar Prospector, Genesis, Deep Impact, Stardust, Kepler, and GRAIL. CONTOUR was lost shortly after its launch in 2002. The three missions currently in development, operation, or analysis phase are MESSENGER, Dawn, and InSight. Four missions of opportunity, ASPERA-3, Netlander, the Moon Mineralogy Mapper and Strofio, have been selected. Netlander was terminated before launch. Aspera-3 is currently operating on ESA’s Mars Express. The Moon Mineralogy Mapper operated on ISRO’s Chandrayaan-1. Strofio is currently in development for the joint ESA-JAXA BepiColombo mission. Additionally, three investigations reusing existing spacecraft have completed operations: EPOCh and DIXI were hosted by the Deep Impact spacecraft and were joined to produce the EPOXI mission, and Stardust-NExT was hosted on the Stardust spacecraft.
