i case study

Client Need:

Sierra Space was looking for a partner to design and manufacture a system of platforms to provide access to the Cargo Module of the Dream Chaser during the installation process of internal and external details. In addition to the product deliverables, Sierra Space required extensive project management, design reviews, product testing and analysis, and quality management.


Spika designed and manufactured four unique systems to be used for specific locations and tasks on the space vehicle. They included:

  • Side access platforms with extended slider reach and deflection restrictions.
  • Tall, partially prone tilt-out platforms with incorporated vacuum plumbing.
  • End access platforms with a diving board design protruding into inside areas of the space vehicle.
  • Platforms with a non-FOD-producing slide-out and extendable ladder.

Technical Information:

  • Allowed for side, top, forward, and aft access.
  • Provided personnel access to the Cargo Module from the forward and aft openings.
  • Ensured FOD control and ESD control in the clean manufacturing environment.
  • Ensured movement limitations (rigidness) of the platform to prevent inadvertent space hardware contact.

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.
