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

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.

President Trump says it perfectly. A patchwork of 50 different state systems creates a maze of conflicting regulations, resulting in chaos. Follow me to join the conversation on leading the AI revolution.

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

We have successful completed Critical Design Review for the @SemperCitiusSDA’s Tranche 2 Tracking Layer, affirming technical readiness to begin production of advanced missile tracking satellites for the Proliferated Warfighter Space Architecture. Press Release:

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. We believe this approach will provide us with the flexibility to address the nation’s most pressing national security space

AI agents are moving from demos to teammates. Part I of our playbook covers the foundations: what an agent is, how it’s structured (objective, instructions, tools, content grounding), and how to spot high-impact use cases—so you can ship secure, reliable agents at scale.

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),

We have been awarded a contract by @MHI_Group to deliver key components for spacecraft docking on the International Space Station. This includes a passive common berthing mechanism, connection hatch, lighting system, and pressure sensor technology. The components will ultimately

Our team has successfully completed the Cybersecurity Maturity Model Certification (CMMC) 2.0 assessment with zero findings. This significant milestone emphasizes our unwavering commitment to cybersecurity and positions us as a leader in compliance and security within our

Inside Gateway: The Deep Space Launch Complex, see a mock-up of @SierraSpaceCo's Dream Chaser spaceplane. The design of Dream Chaser was inspired by the space shuttles but introduces modern advancements. Learn more about Dream Chaser and the Space Shuttle Program at

We are pleased to announce the opening of our new Power Station Technology Center in Colorado. This $45M facility will enable efficient high-volume production of our revolutionary solar power systems, including production for national defense applications. The Power Station has

Today we are chartering a new operation dedicated to supporting national security space as a prime contractor: Sierra Space Defense. This will include expansion plans with a new production facility called “Victory Works,” adding 60,000 square feet of manufacturing space and

Modern advancements in space technology are playing a crucial role in shaping our vision of the future. By leveraging the unique conditions of space, we aim to drive innovation and discovery across various fields. We are dedicated to making space more accessible to a broader

You remember COVID era censorship, right? They banned us from their apps. They deplatformed alternate views and tried to silence any form of opposition. That's why we built Unplugged. So when the chips are down, we know we have an independent platform that will have our back.

Just as microgravity dramatically changes the game in medicine and manufacturing, plants also act very differently in microgravity. The Advanced Plant Habitat (APH) was developed to research growing vegetables in LEO’s unique conditions to provide a reliable food supply. It was

We have been awarded a contract from NASA, under the NextSTEP-2 Appendix R, to study the use of our expandable space station technology on the moon. The purpose of this contract is to develop innovative solutions for lunar surface logistics and mobility, supporting NASA’s moon

Memorial Day is a time for us to honor and remember the brave men and women who have made the ultimate sacrifice in service to our country. It is a solemn reminder of the profound cost of freedom and the selfless acts of courage displayed by our military personnel. In

Dream Chaser is preparing for a groundbreaking mission that could transform cancer treatment. The spaceplane is set to carry a 3D-printed module designed by Merck, leveraging the unique properties of space-grown crystals. With gentle reentries to protect cargo and lower costs,

Our VR35K-A upper stage VORTEX engine, developed in conjunction with the Air Force Research Laboratory, provides 35,000 lbf thrust and high specific impulse using liquid oxygen and liquid hydrogen for increased launch capability. In order to make space more accessible, we have

Our Surface Mount Technology (SMT) solar array is a game-changing technique that increases power density, reduces lead-time, and lowers system costs. By utilizing a surface mount capable cell, pick-and-place automation replaces the time-consuming solar panel assembly process.

We have had another successful demonstration of our Resilient GPS (R-GPS) technology for the U.S. Space Force (USSF). In this third milestone, our team demonstrated an early integration of the R-GPS satellite technology through FlatSat flight software and hardware subsystem
