1 INTRODUCTION

1.1 Scope

This Statement of Work (SOW) defines the effort to be contracted in support of the Goddard Space Flight Center (GSFC) Mars Sample Return (MSR) Capture, Containment and Return System (CCRS) for the design, fabrication, assembly, testing, and delivery of the Spin Eject Mechanism

(SEM).

1.2 MSR CCRS Overview

MSR is an effort to bring samples of Martian rocks and soil back to Earth, where they can be investigated in unprecedented detail, using all the capabilities of terrestrial laboratories. It is part of NASA's Mars Exploration Program, a long-term effort of robotic exploration of the Red Planet.

NASA is collaborating with its various centers and the European Space Agency (ESA) to develop the advanced technologies and hardware needed for the campaign.

The sample return mission architecture is designed to continue the work begun by NASA's Mars 2020 rover. The 2020 rover will collect samples on Mars and stash them on the planet’s surface for subsequent return to Earth. A follow-on campaign will include NASA-led Sample Retrieval Lander (SRL) that would launch the retrieved samples into Mars orbit, and an ESA-led Earth Return Orbiter (ERO) that would rendezvous with the samples in Mars orbit and bring them back to Earth (Figure 1-1).

Figure 1-1: MSR Architectural Overview

1-2

CCRS is the payload on the ERO, shown in Figure 1-2.

The main functions of CCRS are:

• Capture, containing and orientating the Orbiting Sample (OS)

• Transferring contained OS to the CCRS clean zone

• Performing Earth Entry System (EES) in-flight assembly

• Protect EES from micro meteoroid damage

• Precision separation of EES from ERO

• Delivery of EES with contained OS to Utah Test and Training Range (UTTR)

Figure 1-2: CCRS Functional Description (Reference Only)

1.3 Spin Eject Mechanism

The Spin Eject Mechanism (SEM) is an integral part of the CCRS. It is responsible for restraining the EES during launch, cruise, and robotic operations while in Martian orbit. To facilitate robotic operations, the SEM requires a hollow inner diameter for robotic access to install the Contained Orbiting Sample (C-OS) SCV Lid, and EES Lid onto the EES Aeroshell. Once all these components are assembled, shown in Figure 1-4. The SEM is then responsible for restraining the EES during transport back to Earth, and finally ejecting the EES safely back to Earth.

Images detailing the CCRS architecture are shown in Figure 1-3 . The SEM is part of the primary load path into the EES for all mission stages.

1-3

Figure 1-3: CCRS Architecture (Reference Only)

Figure 1-4: EES Assembly Description (Reference Only)

1-4

1.4 Basic Description

In its most basic description, the SEM can be imagined as a hollow cylinder that provides a deployable structural load path between the CCRS Structure and EES. This interface needs to be strong enough to react launch loads while also remaining separable to provide precise and controlled ejection energy into the EES during the payload ejection event to return the payload to Earth.

Figure 1-5: EES-SEM Interface (Reference Only)

The design envelope for these components will be controlled by Mechanical Interface Control documents outlined in MSR-CCRS-ERM-SPEC-0002.

Note: Images shown in Figure 1-2 through Figure 1-5 are notional design concepts for reference only. These do not represent a flight proven design.

3.1.6 Prototype (PT)

Prototypes (PT) are early “Proof of Concept” units intended to buy down risk for subsequent builds. Prototypes could be a scaled mockup or full-size versions of critical assemblies or sub-assemblies. Prototypes may be fabricated out of rapid prototyped parts (3D printing, plastic, or metal) and inexpensive Commercial Off-the-Shelf (COTS) components. The intent of these types of PT units are to verify and provide confidence that the overall mechanism kinematics and mechanism design is sound and robust.

3.2 Spare Parts Kit

The Contractor shall design, fabricate, test and deliver spares parts for any components that are limited life, require refurbishment by an OEM supplier, or would otherwise cause an unacceptable schedule delay if needed during the spacecraft I&T program. Examples include Hold-Down Release Mechanism (HDRM) restraint bolts and HDRMs that require factory refurbishment or replacement.

The spare parts kit shall include enough spare parts to allow a minimum of ten (10) test deployments during the spacecraft I&T program.

A proposed spare parts list shall be provided as part of the Design Review package. NASA review and approval of this list shall be obtained prior to proceeding with manufacture as part of

MRR.

SOW.

• Full Compliance, with exception: The Contractor fully meets the intent of the requirement, but with an exception. (i.e. a different industry standard is used or an internal work instruction). Additional details on the specific exception shall be provided. This scenario will require the Contractor to submit a Request for Waiver (RFW) form.

• Partial-Compliance: The Contractor meets some subset, but not all of the requirement as defined by the MAR. Additional details on the specific shortcomings of compliance shall be provided. Under this scenario the Contractor shall submit a Request for Waiver (RFW) form.

• Non-Compliance: The Contractor does not meet any aspect of the requirement as defined by the MAR and SOW. Under this scenario the Contractor shall submit a Request for Waiver (RFW) form.

As the MAR is a program-level document whose contents may not be applicable to all component-level hardware builds, the Government will address exceptions, partial, and non-compliances on a case-by-case basis as part of the negotiations during the contract award process. Waivers may be granted where permissible.
