Sierra Space

Dream Chaser has successfully completed a series of critical pre-flight tests at NASA’s Kennedy Space Center, marking continued progress toward it's first free-flyer mission.   As part of its rigorous testing campaign, Dream Chaser underwent Electromagnetic Interference and Electromagnetic Compatibility (EMI/EMC) testing, as well as tow testing. During tow testing, the spacecraft was pulled at high speeds by a fifth generation Freightliner Cascadia truck. This process simulated key dynamics and validated autonomous navigation parameters essential for runway landing operations. Press Release: https://lnkd.in/eT_7xm8C

This #VeteransDay, we salute all veterans, including the men and women at Sierra Space who have served our country. Thank you for your service and your sacrifice.

This week, HTV-X1 successfully docked with the ISS, marking a key milestone for the mission. Our team's contributions to the vehicle included PCBMs, hatches, navigation lights, internal lights, and cabin sensors. We’re proud to support this achievement and the spacecraft’s role in advancing space operations. Video by JAXA Astronaut Kimiya Yui

We have successful completed Critical Design Review for the Space Development Agency’s Tranche 2 Tracking Layer, affirming technical readiness to begin production of advanced missile tracking satellites for the Proliferated Warfighter Space Architecture. Press Release: https://lnkd.in/eJPC5TuW

Dream Chaser’s first flight will be a free-flyer, demonstration mission, which is expected to prove the technology and deliver critical data to NASA - National Aeronautics and Space Administration. We believe this approach will provide us with the flexibility to address the nation’s most pressing national security space challenges, while continuing to advance Dream Chaser’s capabilities for NASA and commercial customers. Our team will be prioritizing first-flight readiness with Dream Chaser, targeting a launch in late 2026 to align with expected launch vehicle availability as we position Dream Chaser as a national asset available for future national security and defense demonstrations.

Today, Sierra Space is proud to serve as the Implementation Partner for two customer payloads that just launched to the International Space Station on Northrop Grumman NG-23. Yuri Science Taxi – A facility supporting up to 38 life science experiments in microgravity, operating through 2026. LEOcloud Micro Datacenter – A first-of-its-kind cloud computing payload providing commercial and government cloud services from low Earth orbit. Our team guided both payloads through certification, safety, requirements, and mission readiness to ensure successful flight. We are honored to support Yuri and LEOcloud in advancing science and technology on the ISS.

The Power Station is our new production facility for manufacturing defense-hardened Surface Mount Technology (SMT) solar arrays with industry-leading power density, resiliency, and short production lead times. Utilizing SMT solar cells attached to Printed Circuit Boards (PCBs), assembled with commercial pick-and-place technology, these high-efficiency multi-junction MWT “micro-cells” enable automated production, higher power densities, and faster lead times. This innovation supports both small- and large-scale deployable missions while offering superior performance compared to traditional solar panels. Full video: https://lnkd.in/eAqAAYgN

Today on #NationalInternDay, we celebrate the 13 incredible interns who’ve brought fresh ideas, boundless energy, and curiosity to Sierra Space this summer. From engineering breakthroughs to creative problem-solving, they’ve shown us what’s possible when passion meets purpose. Learn more about our internship program: https://lnkd.in/e7HGP57V

This week, our team members Robert Richter and Sam Moffatt attended the ICES Conference in Prague to showcase our Environmental Control and Life Support Systems (ECLSS). These products and subsystems include Air Revitalization Systems, Pressure Control Systems, Water Recovery & Management, Waste Management, Thermal Control Systems, Crew Systems, and In-Situ Resource Utilization, all of which are vital to supporting life in space.

We have been awarded a contract by Mitsubishi Heavy Industries to deliver key components for spacecraft berthing on the International Space Station. This includes a passive common berthing mechanism, connection hatch, lighting system, and pressure sensor technology. The components will ultimately be used by JAXA: Japan Aerospace Exploration Agency for space station missions. Press Release: https://bit.ly/4eNzjtn
