Mark Sirangelo has resigned from Sierra Nevada Corporation (SNC) for what CEO Fatih Ozmen, owner says are personal reasons, Space News reports. He had run SNC’s Space Systems Division for nearly a decade after his former company, SpaceDev, was acquired.

“We are proud and grateful for all we have achieved in partnership with Mark over the last ten years,” Ozmen said. “Mark has an inspiring enthusiasm for space and a strong entrepreneurial spirit, both of which he has cultivated among our exceptionally talented Space Systems team.”

In an internal memo, Sirangelo said his departure was a “friendly transition” from the company and “is being made from a positive personal place.” The memo, obtained by SpaceNews, was first published by SpaceRef.

“I understand this change may be perceived as challenging but I wanted you to know that the state of our business is very good with strong leadership behind it,” Sirangelo said in the memo to employees. “We were a founding entity of the new commercial space industry and are now seen as one of its most successful leaders.”

Sirangelo said that Fatih Ozmen and Eren Ozmen, the president and co-owner of SNC, were “completely and positively committed” to its space systems business, and that he had been working with them on a transition plan for his departure for weeks. Sirangelo said he would work with company leadership on transition activities through July and serve in a “strategic advisory capacity for some time” after leaving the company.

Paragon Developing Advanced Radiator for Inflatable Habitats

Paragon Space Development Corporation will develop a flexible radiator for inflatable habitats and an improved condenser for use on human space missions with the help of NASA funding.

The space agency has selected the Tuscon, Ariz.-based company for two contracts under its Small Business Innovation Research (SBIR) Phase 1 program. The agreements are worth up to $125,000 apiece over 13 months.

The target market for Paragon’s Flexible Radiator (FlexRAD) is “long duration human spaceflight exploration missions and other spacecraft” that use a single loop  active thermal control system (ATCS).

EXECUTIVE SUMMARY

The NASA Transition Authorization Act of 2017 (P.L. 115-10) provided for an ISS Transition Report under section 303:

The Administrator, in coordination with the ISS management entity (as defined in section 2 of the National Aeronautics and Space Administration Transition Authorization Act of 2017), ISS partners, the scientific user community, and the commercial space sector, shall develop a plan to transition in a step-wise approach from the current regime that relies heavily on NASA sponsorship to a regime where NASA could be one of many customers of a low-Earth orbit non-governmental human space flight enterprise.

SPARKS, Nev. (February, 7, 2018) – Sierra Nevada Corporation (SNC) received NASA’s Authority to Proceed for the Dream Chaser spacecraft’s first mission, with a launch window for late 2020. The mission will provide cargo resupply to the International Space Station under the Commercial Resupply Services Contract 2 (CRS2).

“SNC has been successfully completing critical design milestones as approved by NASA, and having a timetable for the first launch is another important step achieved for us,” said Fatih Ozmen, owner and CEO of SNC.  “The team has worked so hard to get to this point and we can’t wait to fulfill this mission for NASA.”

Key Mission Capabilities:

  • Delivers up to 5,500 kg (12,125 lb) of pressurized and unpressurized supplies and scientific research payloads
  • Remains attached to the space station for extended periods so crew can transfer cargo and perform science laboratory operations
  • Flying laboratory that allows scientists to send commands, receive data in real-time
  • Powered payload science experiments can operate continuously during the mission
  • Critical science is conducted from the pressurized cabin (crew-tended or autonomous)
  • Unpressurized cargo/experiments are transferred to or from the space station via robotic operations
  • Returns up to 2,000 kg of cargo via pinpoint landing at NASA Kennedy Space Center (KSC) Shuttle Landing Facility (SLF) for immediate post-landing handover to customer, maximizing the integrity of data collected on-orbit

“The Dream Chaser is going to be a tremendous help to the critical science and research happening on the space station,” said Mark Sirangelo, executive vice president of SNC’s Space Systems business area. “Receiving NASA’s Authority to Proceed is a big step for the program. We can’t wait to see the vehicle return to Kennedy Space Center to a runway landing, allowing immediate access to the science payloads being returned from the station.”

SPARKS, Nev. (January 25, 2018) – Sierra Nevada Corporation (SNC) has formalized its agreement with NASA under Next Space Technologies for Exploration Partnerships-2 (NextSTEP-2), signing a contract to design and develop a prototype for a deep space habitat. The formal signing of the contract under NextSTEP Broad Agency Announcement, Appendix A: Habitat Systems, aimed at enabling potential long-duration human missions in deep space, clears the way for actual production of SNC’s prototype in the coming months.

SNC is partnering with Aerojet Rocketdyne and ILC Dover to begin the conceptual architectural design; they will build a full-scale ground prototype of the main habitable volume over the next 19 months.

I realize it’s a bit late, but here’s a look back at the major developments in space in 2017.

I know that I’m probably forgetting something, or several somethings or someones. Fortunately, I have eagle-eyed readers who really seem to enjoy telling me just how much I’ve screwed up. Some of them a little too much….

So, have at it!  Do your worst, eagle-eyed readers!
