Helping Humans Survive in Space

“We [humans] put out CO2 and moisture,” explained Grant Anderson, CEO of Paragon Space Development Corporation. “If you don’t take these out of the air in a spacecraft, water can condense, causing bacteria growth, shorting out equipment, or clogging critical airflow passages, and the CO2 can cause carbon dioxide poisoning.” 

Needless to say, such events are unacceptable and are why consideration of a humidity control system in a spacecraft is highly critical.

Stephanie Chiesi, senior systems engineer, worked on the humidity control subassembly for Boeing’s Crew Space Transportation (CST)-100 spacecraft while she was at Paragon Space Development Corporation. The team that Chiesi was part of designed the humidity control subassembly system for NASA’s commercial crew program.

“Humidity control in a spacecraft is unlike the system for your house, because you have to take into consideration the closed loop environment of the vehicle, as well as the conditions the system needs to survive during launch and reentry,” Chiesi explained, “factors which aren’t part of the day to day concern for humidity control in a house on Earth.”

“That’s why Vitech’s CORE [systems engineering software tool] was so helpful as we designed the CST-100,” Chiesi said.  More...

Looking forward while remembering the past

David Long, then director of product development, tends to matters at the Vitech booth at the National Council of Systems Engineering in St. Louis in 1995.

This is Part I in an occasional series on the history of Vitech Corporation.

As a new year opens, Vitech Corporation anticipates celebrating a significant milestone: 25 years in business. It’s been a quarter century of growth that has paralleled the growth of systems engineering itself.

But it was a venture that almost didn’t happen. David Long, president of Vitech, founded the company in 1992. The undertaking which began as an undergraduate project has grown to become an enterprise with a product used by thousands across the globe. It all started rather by accident.  More...
