OVERVIEW

The James Webb Space Telescope (JWST) is an orbiting infrared observatory that will take the place of the Hubble Space Telescope at the end of its mission. Genesis Engineering Solutions was contracted to develop the Integrated Science Instrument Module (ISIM) Electronics Compartment (IEC) also knows as Region 2 of the JWST. This involves developing a light weight composite structure with optical reflective louver systems; this heat emitting system functions as a state-of-the-art radiator for space application.

The goal of the JWST is to study the 
universe at the important but previously unobserved epoch of galaxy formation. It will peer through dust to witness the birth of stars and planetary systems similar to our own. Utilizing JWST, scientists hope to get a better understanding of the intriguing dark matter problem. JWST is also a key element in NASA’s Origins Program.

— Hardware Procurement
— PWA Manufacturing

DETAILS

Modular Unified Space Technology Avionics for Next Generation (MUSTANG), also known as MMS Derived Avionics (MDA), was developed using GSFC internal funds and funds from the Goddard Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) mission. It is baselined for PACE, the Goddard Ocean Color Instrument (OCI), the Goddard Global Ecosystem Dynamics Investigation (GEDI) Power Controller Unit, and the JPL Multi-Angle Imager for Aerosols (MAIA) Instrument Electronics. The designs, although not the form factor, for the processor, comm card, low voltage power supply, power monitor card, solar array module, segment module, heater module, and engine valve driver have been adopted by the WFIRST project. The Goddard team has worked closely with key Goddard contractors, such as Genesis Engineering, who supported the design and manufacture of a number the MUSTANG cards.

OCI PACE

Ocean Color Instrument - Plankton, Aerosol, Cloud, ocean Ecosystem

OVERVIEW

Measuring the color of the ocean provides important information about the health of the Earth’s oceans. The ocean is composed of many different substances which can contribute to the scattering of light at different wavelengths. One important substance is phytoplankton (marine based algae) which contributes to the greenish color of the ocean and is used to monitor and is an important sink for carbon dioxide.

OCI Optical Analysis

We are supporting the OCI (Ocean Color Instrument) by working in the analysis of the OCI optical system. Stray light can interfere with the quality of the OCI measurements by affecting its accuracy. Stray light analysis helps to ensure that the OCI is measuring what it intends to and that most of the errant light entering the optical system is blocked by the detector. Optical tolerancing analysis provides an overall uncertainty budget in the optical systems ensuring that the instrument will meet its goals.

SPS

Single Person Spacecraft

OVERVIEW

The Single Person Spacecraft (SPS) is an example of our ongoing investment in R&D. The SPS provides a unique alternative to the concept of a spacesuit. When extra-vehicular activity (EVA) in space has required an astronaut with spacesuit there are inherent challenges. The SPS has advantages for both the astronaut and the overall activities that need to be accomplished.

DETAILS

Designed for servicing / exploration of ISS, NEOs and satellites. It can be piloted or tele-operated. Using the same atmosphere as the host vehicle it provides immediate access to space without pre-breathing or airlock. Integral propulsion enables rapid transport to the work site. It is sized to for all crew members providing “shirt sleeve” operations of conventional displays and controls.

PLANNED USES

NEAR EARTH OBJECTS 

SaTELLITES & TELESCOPES 

LCRD

Laser Communications Relay Demonstration

OVERVIEW

The Laser Communications Relay Demonstration (LCRD) mission is NASA’s first, long duration optical communications mission. The project will help mature concepts and deliver technologies applicable to both near- Earth and deep space communication network missions.

The investigation will enable a variety of robust, future science and exploration missions, providing a higher data rate and delivering more accurate navigation capabilities with reduced size, weight and power requirements.
