Timeline 18
Timeline 19
Philosophy of Solicitation • Science Leads the Way – Selected team(s) must execute and deliver well-defined Legacy Science Program(s) – Prioritize instruments that enable broad community usage and/or data of high archival value, but also allow for agile, “niche” instruments to solve important / outstanding science questions • Technology to Meet the Needs of Science – Solicitation allows for: • new instruments • upgrades/modifications to existing instruments – Allow for flexibility for future enhancements and modifications to NGSI • Flexibility to Propose What The Science Needs – Allow for a nominal three-year development period after funding begins but also allow for longer or shorter development timescales for optimal science return – Allow for schedule and budget flexibility; make selections based on science return on investment – Reduce requirements for the Instrument Concept Study (ICS) phase compared to previous solicitations – Make instrument development and acceptance process easier for teams (using lessons learned from past experience) 20
Legacy Science Programs (LSP) - Requirements • The LSP must contain: – A detailed scientific justification – An observing plan which clearly describes the science targets, instrument modes and the time required to achieve the scientific goals – The roles and expertise of the science team that will execute the LSP. • It should be executable within a two year period following commissioning • Nominally LSP data have no period of exclusive use • In the ICS phase and after commissioning, the proposing team(s) may refine the needed observing time (possibly based on a better understanding of the instrument) but may not change the scope of the scientific investigation. What Legacy will Your science leave? 21
What Has Not Changed This Time • Solicitation issued and selections made by NASA HQ • Instrument development overseen by the NASA SOFIA Program • Proposals are solicited from universities, industry and NASA centers • Instrument upgrade proposals are also encouraged • Foreign instrument proposals from countries other than Germany are solicited, on a no exchange of funds basis 22
What Has Changed This Time • The instrument development period is longer than the last time (nominal ~3 yrs vs. 2 yrs) • Solicitation strongly emphasizes a Legacy Science Program (LSP) to be executed by proposing team that motivates the new instrument(s) • Intent is to make the instrument development and acceptance process easier • Instrument Concept Study phase requirements significantly reduced compared to last time • Funding profile not to exceed ~$15-20M over three years starting after ICS phase, unless strongly justified • Science Exploitation Period (SEP) following commissioning for up to 2 years – SI team conducts their Legacy science – Science community will also do science with SI team support • New SI is turned over to the Program after the SEP 23
