ETD provides end-to-end engineering support to all projects within Goddard Space Flight Center focusing on the following areas:

Lunar Orbiter Laser Altimeter (LOLA)

Spitzer/Infrared Array Camera

Earth and Space
  • State of the art scientific instruments
  • Sub-orbital to orbital (small to medium) scope scientific missions
  • Flagship scientific observatories missions
  • End-to-end data systems
  • Avionics systems communications and navigation
  • Situational awareness and decision-making tools
Space Operations
  • Flight Dynamics Facility and navigation systems
  • Ground and space communications network
  • Operations systems

We develop high performance and cost effective solutions to the most challenging problems on flight missions ranging from suborbital projects—including balloons, sounding rockets, and airplanes—to interplanetary probes and flagship observatories.  In addition, we acquire and distribute science data worldwide.

Examples of missions we currently support:


GPM Image The Global Precipitation Measurement (GPM) mission is one of the next generations of satellite-based Earth science projects that will study global precipitation (rain, snow, ice) levels.


JWST Image The James Webb Space Telescope (JWST) is a large, infrared-optimized space telescope that is designed to study the earliest galaxies and some of the first stars formed after the Big Bang.


SDO The Solar Dynamics Observatory (SDO) will further our understanding of the sun's influence on Earth and near-Earth space by studying the solar atmosphere on small scales of space and time, and in many wavelengths simultaneously.

Sample Analysis at Mars (SAM) Instrument The Sample Analysis at Mars (SAM) is a suite of instruments that will be onboard the Mars Science Laboratory (MSL) rover and will address three of the most fundamental questions about the ability of Mars to support life - past, present, and future.


The Lunar Reconnaissance Orbiter (LRO) The Lunar Reconnaissance Orbiter (LRO) is an unmanned mission to create the comprehensive atlas of the moon's features and resources necessary to design and build a lunar outpost. LRO focuses on the selection of safe landing sites, identification of lunar resources and the study of how lunar radiation will affect humans.

TDRSS The Tracking and Data Relay Satellite (TDRS) System (A through J) consists of a constellation of geosynchronous satellites and associated ground systems that operate as a bent-pipe relay system between customer platforms and customer ground facilities. Future TDRS satellites will help replenish the fleet.
