1 INTRODUCTION

The Space Weather Next Lagrange 1 Series (L1 Series) Coronagraph shall be a Sun-pointing imaging instrument designed to accommodate the brightness range of the solar scene and detect transient and small local increases in solar coronal brightness associated with Coronal Mass

Ejection (CME) plasma density pulses. The instrument must measure the coronal white light intensity enabling determination of CME velocity, direction, width, and mass. A CME is an eruption of solar plasma that propagates at velocities of a few hundred to a few thousand kilometers per second outward into the heliosphere. To an observer on earth, an Earth-directed

CME is viewed as a radially expanding circle of enhanced brightness encircling the Sun. The velocity of CMEs is obtained from two or more CME time-lapse images showing the radial expansion of the CME circle. A CME plasma density increase is observed by the detection of solar photons that are Thomson-scattered by coronal plasma electrons. The CME mass is proportional to the scattered photons.

NOAA NESDIS has the responsibility to provide continuity of critical space-based space weather observations consistent with the goals outlined in the National Space Weather Strategy and Action Plan (https://www.sworm.gov/publications.htm). Design, development and deployment of satellite systems to meet this responsibility is through a joint NOAA/NASA

Space Weather Observations (SWO) Program Division within the Goddard Space Flight

Center’s Flight Projects Directorate. The SWO Program Division is exploring the possibility for industry partners to build subsequent coronagraph instruments.

NOAA and NASA acknowledge that there may be industry interest to either collaborate in the use of compact coronagraph (CCOR) technology developed by Naval Research Laboratory

(NRL) or to independently develop or use their own coronagraph technology or solution.

Any industry partner that wishes to collaborate with NRL or use CCOR technology from NRL is required to be certified in the Joint Certification Program (JCP). The Joint Certification Program

(JCP) certifies United States (U.S.) contractors for access to unclassified military technical data belonging to the U.S. Department of Defense (DOD). An active DD2345 "Military Critical

Technical Data Agreement" is required to access unclassified technical data with military or space application and may be required to partner with NRL. Any partnership with NRL, like any subcontracting agreement, is the sole responsibility of the industry partner; NOAA has no preference or preferred method of implementing the commercial Coronagraph development, other than to assure mission success, minimize cost, and meet schedule and mitigate risks.

It is anticipated that at the conclusion of this Phase A study any industry partner will be prepared to enter directly into a Systems Requirements Review approximately one month after

Implementation contract award followed by a Preliminary Design Review. The Government will consider a Contractor proposed pre-priced option for four (4) (TBR) additional months of performance that mitigates technical, cost, and schedule risk associated with the Coronagraph

design, development, and delivery, and moves the completion of this formulation study towards a Preliminary Design Review level readiness.

1.1 Top Level Summary of Work Required

The details of the deliverables are described in later sections. At the top level, the Government requires:

a) A Coronagraph Design that satisfies the baseline requirements defined in the

Coronagraph Specification (SPEC) and Coronagraph Mission Assurance

Requirements. Suggested feedback to Coronagraph SPEC driving requirements, enhancements to the design beyond the baseline requirements will be considered if they mitigate risk, schedule, cost, and can be implemented within the specified delivery timeline.

b) Feedback and an assessment of Coronagraph performance against requirements specified in the SPEC.

▪ Detailed discussion on SPEC requirements of Scene Coverage, Spatial

Resolution, Measurement Range, Accuracy, Refresh Rate and Latency, and

Data Rate is anticipated during this study.

c) Trade Studies as described in section 2.1 (TBR)

▪ Industry partner proposed trade study(s)

d) Technical Analysis as described in section 2.2

e) Notional Development Schedule as described in section 2.4

f) Cost Analysis as described in section 2.4

g) Technology Readiness Level (TRL) Assessment and a Technology Development

Plan as described in section 2.3

h) Identification of Development Risks as defined in section 2.4

i) As applicable, performance of any work awarded for Technology Development and/or Risk Mitigation effort(s)

j) Identification of hardware and software heritage assumptions as defined in section 2.3

1.2 Guiding Assumptions About the Eventual Flight Program
