POC - address and phone number Organizational Conflict of Interest (OCI) In addition to the information requested above, NASA/JSC is requesting information from industry regarding potential organizational conflicts of interest (OCI) arising from the USDV contract.� The nature of the work anticipated under the USDV contract may create the potential for OCI(s) as currently described in FAR Subpart 9.5.� Each interested party should review FAR Subpart 9.5 in light of NASA�s anticipation of OCI issues and consider carefully the extent to which an OCI may arise before making the decision to compete for the USDV contract. Specifically, NASA anticipates that the effort under the USDV will include the following types of tasks which could lead to potential OCI issues.� This list is not all inclusive. Contractor may provide support in terms of preparing specifications or work statements, which would give rise to a biased ground rules OCI. Contractor may have access to another company�s proprietary, business confidential or financial data and/or non-public Government sensitive information, which would give to an unequal access OCI. Contractor may be required to perform technical reviews or provide consultation services on its own offers, products, or services (or those of its affiliate(s) or competitor(s)) provided under a different contract(s), which could create an impaired objectivity OCI. Interested parties are requested to address the following questions: 1.�� What type(s) of OCI issues would your company or potential team identify, if any, should you choose to propose on the USDV contract? 2.�� What strategies would you anticipate proposing to mitigate the OCI issues that you identified (if any)?� Please provide strategy details, previous examples/experience with other contracts with NASA or other agencies, etc. 3.�� Are there any other types of potential OCI issues with the USDV contract that were not identified in this RFI (assuming any were identified)? 4.�� Does your company foresee any OCI issues associated with the USDV contract that would cause you to decide not to propose on the potential USDV RFP? NASA will review any responses received regarding potential OCI and each offeror�s proposed OCI mitigation strategy.� NASA will respond to each company who submits a mitigation strategy.� NASA�s response is not intended to serve as a confirmation that, in fact, all potential OCI have been identified, an OCI will ultimately exist, or that an interested party is capable of successfully eliminating or mitigating an identified OCI.� NASA�s response is also not intended to encourage or discourage any interested party from responding to an RFP issued for USDV contract in the future.� Furthermore, NASA�s response in no way alters or interprets FAR 9.5 as it applies to a final statement of work or a final proposal submission, should an interest party elect to submit a proposal to an RFP for USDV contract.� Subsequent to the initial OCI submission and NASA�s response, NASA will not consider further information as it relates to this RFI. NASA will not affirmatively release any information received in response to this RFI to the public but may use information received in developing the best approach for a contract strategy, and therefore such information may be recognizable to the interested party who submitted it.� Any information submitted in response to this RFI that is marked as �Confidential Commercial or Financial Information� will be considered as voluntarily submitted in accordance with the Freedom of Information Act. Executive Order (EO) 13985, Advancing Racial Equity and Support for Underserved Communities Through the Federal Government� � � � Additionally, in support of the Executive Order (EO) 13985, Advancing Racial Equity and Support for Underserved Communities Through the Federal Government, NASA is seeking to advance equity or remove barriers for members of underserved communities related to this requirement. As defined in the EO, Underserved Communities refers to populations sharing a particular characteristic, as well as geographic communities, that have been systematically denied a full opportunity to participate in aspects of economic, social, and civic life, as exemplified by the list in the preceding definition of ""equity."" Equity means the consistent and systematic fair, just, and impartial treatment of all individuals, including individuals who belong to underserved communities that have been denied such treatment, such as Black, Latino, and Indigenous and Native American persons, Asian Americans and Pacific Islanders and other persons of color; members of religious minorities; lesbian, gay, bisexual, transgender, and queer (LGBTQ+) persons; persons with disabilities; persons who live in rural areas; and persons otherwise adversely affected by persistent poverty or inequality. NASA seeks input in the following areas: 1.

Please reference 80JSC022ISSDeorbit RFI#2 in any response.� --- Mod 1 Legacy Posting Info: This is Modification 1�to the special notice entitled ""International Space Station Deorbit Capability"",�80JSC022ISSDeorbit,�which was posted on August 19, 2022. You are notified that the following change is made:� 1. The due date for responses�is�extended to September 16, 2022. THIS IS NOT A REQUEST FOR PROPOSAL (RFP). NO PROPOSALS ARE TO BE SUBMITTED IN RESPONSE TO THIS NOTICE. This notice is issued by the National Aeronautics and Space Administration (NASA)/Johnson Space Center (JSC) to solicit responses from interested parties to gauge industry�s capabilities to provide deorbit capabilities for the International Space Station (ISS). This document is for information and planning purposes and to allow industry the opportunity to verify the reasonableness and feasibility of the requirement, as well as promote competition.� Background: The ISS is a large, complex, multi-national space station operated in low-Earth orbit by the NASA and its International Partners (IPs).� At the completion of ISS operations, currently planned through 2030, the ISS must be safely deorbited via a controlled reentry into an unpopulated region.� It is the responsibility of all ISS partners to ensure the safe deorbit and reentry of the ISS at its end-of-life (EOL). Section 303(c)(2) of the Public Law 115-10, the National Aeronautics and Space Administration Transition Authorization Act of 2017, calls for NASA to perform �an evaluation of the feasible and preferred service life of the ISS beyond the period described in section 503 of the National Aeronautics and Space Administration Authorization Act of 2010 (42 U.S.C. 18353)� and �an identification of the necessary actions and an estimate of the costs to deorbit the ISS once it has reached the end of its service life.� Per ISS International Partner agreement and request, NASA is issuing this Request for Information (RFI) to assess industry�s capability to design, develop, manufacture, launch, and provide the on-orbit operation to enable a controlled re-entry and the safe deorbit the ISS. The deorbit vehicle shall attach (via docking or berthing) to the ISS at least one (1) year prior to the planned ISS reentry date to enable adequate time for on-orbit tests and checkouts.� ISS altitude lowering can occur naturally via atmospheric drag or via Russian propulsive control from the deorbit vehicle rendezvous altitude to the final circular holding altitude at approximately 270 km, where maneuvers will be performed as necessary to establish proper ground tracks prior to the final deorbit burn sequences.� Below 270 km, a combination of natural decay and/or propulsive maneuvers will reduce the ISS perigee to approximately 150 km.� Shortly thereafter, the deorbit vehicle will perform the final reentry burn resulting in a controlled reentry of the ISS within a pre-defined, uninhabited entry corridor.� Throughout the final series of deorbit events, the deorbit vehicle will be responsible for providing both delta-v andattitude control of the ISS. Although nominal ISS EOL is late 2030, the Government requires that this deorbit capability be available as soon as possible to protect for contingencies that could drive early re-entry and beyond 2030 in the event of further ISS mission extensions.� Ground Rules and Assumptions: The deorbit vehicle design and operations shall enable a contingency call-up for launch on-need to support an earlier than nominal plan de-orbit scenario.� This call may be made as late as L-6 months prior to the needed de-orbit date. The deorbit vehicle design and operations shall support a later than nominal plan de-orbit scenario due to the extension of the ISS EOL beyond 2030. The deorbit vehicle shall remain on-orbit in a quiescent mode for a minimum of one year preceding the final deorbit burn. The deorbit vehicle design and operations shall allow rendezvous and attach to the ISS at Node 2 Forward. The deorbit vehicle design and operations shall allow for operational scenarios including both a crewed and uncrewed ISS. The deorbit vehicle design may require complex software development including autonomous operations and failure response late in the deorbit phases. The deorbit vehicle is a must-work function. The deorbit vehicle shall be capable of providing at least 47 m/s of delta-v for the ISS at 450,000 kg mass. The deorbit vehicle shall provide a minimum total thrust of 3236 N. The deorbit vehicle shall provide attitude control for the mated stack throughout the deorbit sequence of events. Additional detail on the concept of operations can be found in the �ISS Deorbit USOS Concept of Operations Overview� presentation attached below. Request for Information: Respondents are requested to provide the following information to assist in NASA's preparation of a potential future Request for Proposal (RFP).
