Integration and Testing Platform for OSAM-1



NASA required a work platform system to support the integration and test activities for the Servicing Payload (SP) and Space Vehicle (SV) for the OSAM-1. KBR contracted with Spika to satisfy this requirement with a height adjustable work platform system that supported four main SP/SV integration height and access configurations. The Spika stand also incorporated an overhead gantry with a 1,200 lb. capacity to support a “mockup” spacecraft used in the testing of the Servicing Payload.

Client Need:

NASA sought out a work platform to support the integration and test activities for both the Servicing Payload (SP) and Space Vehicle (SV) for the OSAM-1 (On-orbit Servicing, Assembly, and Manufacturing 1) mission. The work platform was needed to serve as the walking/working area used to support personnel and equipment during the Integration and Test (I&T) of the Servicing Payload and Space Vehicle. The work platform also had to support a gantry and other MGSE required to perform multiple tests on subsystem functionality for the OSAM-1. The tests would take place within a Class 10K clean room at the Goddard Space Flight Center in Maryland, USA.


Over the course of a year, Spika developed real-time, tailored engineering solutions that satisfied the rigorous and unique requirements for the direct-interfacing flight hardware ground support equipment (GSE). The resulting design provided access for four primary integration activities that required different deck configurations and keep-out zones, as well as different heights, within a Class 10k clean room environment. Spika, KBR, and NASA met regularly throughout this period to revise the concept and review engineering analyses and other objective quality elements (OQEs) provided by Spika for the program.

Technical Information:

  • A Class 10K clean room compliant work platform system
  • A walking/working surface with reconfigurable deck panels and handrails
  • An adjustable working surface height from 126”-224” via non-backdrive-able lifting actuators with brake redundancy controlled at ground level
  • A multi-height stair that provided 126”-224” height range via a manual screw jack at ground level
  • A dedicated overhead structure to support a 1200 lb. “mockup” used in testing of the spacecraft
  • A live load capacity of 3,000 lbs. to support 8 people + tools
  • A dead load capacity of 2,000 lbs. to support various tool/material storage
  • Deck-mounted fall arrest posts
  • Air casters for system mobility
  • Proof Load Test
  • NDT weld inspection for all critical welds
  • Full system powder coat with critical welds masked
  • Full system grounding with grounding studs
  • All material subject to approval by OSAM-1 Contamination Control Engineer

What’s a Rich Text element?

The rich text element allows you to create and format headings, paragraphs, blockquotes, images, and video all in one place instead of having to add and format them individually. Just double-click and easily create content.

Static and dynamic content editing

A rich text element can be used with static or dynamic content. For static content, just drop it into any page and begin editing. For dynamic content, add a rich text field to any collection and then connect a rich text element to that field in the settings panel. Voila!

How to customize formatting for each rich text

Headings, paragraphs, blockquotes, figures, images, and figure captions can all be styled after a class is added to the rich text element using the "When inside of" nested selector system.
