NASAs Science Mission Directorate (SMD) currently sponsors a number of flightmissions, divided between missions in development and missions in operations. One ofSMDs programmatic objectives is to maximize the science return for the Nation within theavailable budget. This Request for Information (RFI) solicits input from the broad spacescience community that would contribute to NASAs study of possible new uses for the NASADeep Impact/EPOXI spacecraft beyond its current mission. Responses to this RFI will beused to inform NASAs program planning.Background:NASA has science missions under development and in operation that send spacecraftthroughout the Solar System, including low and high Earth orbits, station keeping nearSun-Earth Lagrangian points, orbits around every planet from Mercury to Saturn as well asthe Moon and asteroids, drift away Solar orbits, and trajectories out of the Solar Systemand into interstellar space. Each of these missions has science objectives that will berealized through a prime mission and possible mission extensions when the prime missionhas been completed. NASAs science missions are managed by the Science MissionDirectorate (SMD); information on these missions may be found at . It is a programmatic objective of SMD to get more science return from the availablebudget. One way of increasing the science return from NASAs science missions is tocontinue operating the spacecraft after the prime mission has been completed. NASA has abiennial review process, called the Senior Review, to consider and approve the operationof spacecraft and extend the prime science mission.An alternative to extending the prime science mission is to initiate a new scienceinvestigation with an existing spacecraft after the prime science mission has beencompleted. There have been several examples of this in the past, including the 1982approval to use the ISEE-3 spacecraft (renamed ICE) for an encounter with CometGiacobini-Zinner, the 2007 approval to use the Stardust spacecraft for the NewExploration of Temple 1 (NExT) investigation as a follow-on to Deep Impact, and the 2007approval to use the Deep Impact spacecraft (renamed EPOXI) for a study of extrasolarplanets during its cruise to encounter Comet Hartley 2. These new science investigationsrealize unique, high impact investigations that otherwise would cost substantially moreto execute, and they provide high science value for the funds expended.In February 2011, the Deep Impact (EPOXI) spacecraft will complete the Phase E primaryoperations phase of its mission. Details of the spacecraft design and performancecapabilities may be found on the Discovery Programs Science Support Office (SSO) ProgramAcquisition Website at .Links 1 6 on that webpage describe the instruments and remain valid. Links 7 and 8,which describe orbital parameters and fuel budget, are superseded as follows:The orbit of the Deep Impact spacecraft following the Hartley 2 encounter on November 4,2010, has the following characteristics. The elements are in a heliocentric, Earth MeanOrbital reference frame. Deep Impact Spacecraft Orbital Parameters Reference Epoch = December 1, 2010 00:00:00 ET Semimajor axis = 164114602.828260630 km Eccentricity = 0.111215495 Inclination = 3.201462042 deg Longitude of Ascending node = 95.119656916 deg Argument of periapse = 126.186162151 deg Time of periapse passage = -9126823.136892710 sec Mean anomaly = 90.610709095 deg True anomaly = 103.232671772 deg These values are based on the Design Reference Mission (DRM) 230 reference trajectory.Note that there are several maneuvers that will be implemented subsequent to when DRM230was created, and the size of these maneuvers will not be known until the comet ephemerisis improved through the use of approach data. Thus the above values are subject tochange, but the overall characteristics of the orbit are representative and can be usedfor most purposes not requiring extremely high accuracy.Deep Impact Spacecraft Fuel Budget (as of 7/27/10)Event = Fuel UsedFuel use through 7/27/10 (TCM-19) = 78.48 kgFuel use 7/27/10 through Encounter {1}= 1.22 kgUnusable Fuel = 1.15 kgRemaining Fuel (usable)= 4.15 kg {2} Delta V Remaining OR = 17.3 m/s {3}Attitude Control Duration Remaining = 11 19 years {4}Notes:{1} Fuel use 7/27/10 through Encounter includes: 3 TCMs totaling a Delta V Mean of 4.41 m/s (1.04 kg) Reaction wheel desats for attitude control through 12/27 (0.13 kg) Safe Mode (0.05 kg) {2} Uncertainty on amount of usable fuel remaining is -0/+5.8 kg {3} Delta V Remaining calculation uses Isp = 220.6 s this Isp is for small burns, ifburns > 2m/s are used, an Isp of 227.7 can be used, which will yield 17.8 m/s {4} Attitude control duration remaining based on flight actuals: 11 years is for worst case Science Attitude 19 years if for Cruise Attitude In this RFI, NASA is soliciting ideas and suggestions from the science and researchcommunities on potential new uses of the Deep Impact science spacecraft that supportNASAs science goals. A new science investigation using this spacecraft should addressone or more of NASAs science objectives in any of SMDs research disciplines(Astrophysics, Earth Science, Heliophysics, and Planetary Science). NASAs scienceobjectives are described in The Science Plan for NASAs Science Mission Directorate(2007-2016), available at . Note that the reuse of the Deep Impact spacecraft is not limited to a new mission in thePlanetary Science discipline, such as retargeting a planetary science mission to a newdestination, but that this request specifically includes the use of the Deep Impactspacecraft for a new science investigation in a different research discipline. This couldinclude, but is not limited to, the use of this planetary science spacecraft forheliophysics measurements or astrophysics observations.It is not the intent of this RFI to solicit observation requests, i.e. relatively modestchanges such as a single observation using the Deep Impact spacecraft for a short periodof time, but instead to solicit major and entirely new applications for existingspacecraft. With input from responses to this RFI, NASA intends to consider (i) whether there arescience opportunities for new uses of this spacecraft and (ii) whether a solicitation forproposals is warranted to enable such opportunities.If so requested in your response, all information received from this RFI will beconsidered confidential and proprietary; however NASA will use your response to aid inprogrammatic decisions about the future use of existing spacecraft and in the formulationof a potential solicitation for proposals.It is not NASAs intent to publicly disclose proprietary information obtained during thisRFI. To the full extent that it is protected pursuant to the Freedom of Information Actand other laws and regulations, information identified by a respondent as Proprietary orConfidential will be kept confidential. It is emphasized that this RFI is for planningand information purposes only and is not to be construed as a commitment by theGovernment to enter into a contractual agreement, nor will the Government pay forinformation solicited. No solicitation exists; therefore, do not request a copy of the solicitation. If asolicitation is released, it will be synopsized in FedBizOps and on the NASA AcquisitionInternet Service.Requested Information:The response to this RFI will be in the form of a PDF document that is uploaded throughNASAs NSPIRES system (see instructions below).
