Sierra Space

Our Ghost reentry vehicle is designed to deliver critical payloads anywhere on Earth within 90 minutes and stay prepositioned in orbit for years — a gamechanger for logistics in denied or contested environments. Ghost recently took a step toward that vision, putting its capabilities to the test during @US_SpaceCom's Apollo Nexus exercise.

"Getting something into theater to the warfighter when they need it is critical," says Erik Daehler, SVP of Sierra Space Defense. "Space is a perfect logistics node."

More on Ghost's latest test coming soon — read the full story from Vivienne Machi at @AviationWeek:

Warren Jenson has joined our board of directors, where he'll serve as chair of the audit committee.

Warren brings more than three decades of financial, operational and technology leadership—including CFO roles at Amazon, Electronic Arts, Delta Air Lines and NBC, and most recently as president and CFO of Nielsen. He currently serves as CFO of Polymarket and sits on the boards of DigitalOcean, Ripple and Dropbox.

That range gives him a rare view into how businesses build financial discipline at every stage—from early growth to public-company scale—and it's exactly the kind of perspective we want as we take on more complex missions.

Welcome to our team, Warren!

Today, we're excited to share that on a single mission, Dream Chaser® will serve national security, commercial, and civil customers, proving out an operational model where one platform supports the full range of America's space priorities.

"As the space domain has become increasingly contested, Dream Chaser has evolved into exactly what America needs: a strategic national capability built on commercial innovation and investment," said our CEO, Daniel Jablonsky. "We're not just talking about the multi-use space economy, we're operating it."

We built Dream Chaser—America's Spaceplane®—to be a commercial, reusable, runway-capable spaceplane, engineered for deployable wings, hypersonic flight control, autonomous reentry, and sub-1.5g runway landings.

Dr. Robert Morrow, Sierra Space's Lead Plant Scientist, has been awarded the prestigious AIAA Jeffries Aerospace Medicine and Life Sciences Research Award!

Over his 38-year career, Dr. Morrow has pioneered breakthrough plant growth systems for space - including Veggie (the first to produce edible food for ISS crews), XROOTS (which grew the first aeroponically-grown tomatoes in space), and the Advanced Plant Habitat. Together, these systems have successfully grown over 15 plant varieties aboard the ISS.

His work extends far beyond current missions as he continues developing bioregenerative life support systems that will provide oxygen, recycle water, and produce fresh food for long interplanetary journeys.

Congratulations, Dr. Morrow, on this well-deserved recognition! 🌿

We are proud to welcome Jill Pomeroy as Senior Vice President of Government Relations.

As our CEO Daniel Jablonsky noted: "American space leadership requires more than technology—it demands trusted partnerships with Congress and the executive branch to secure the funding, policy frameworks, and programmatic support that our national security and space exploration priorities depend on."

In her role, she will serve as the our principal advocate for shaping policy, securing support at the federal, state and local level, and advancing legislative priorities. Jill brings more than 25 years of leadership experience at the intersection of technology, policy, and national security.

Welcome to the team, Jill!

America’s future in space will be shaped not only by the technologies we build, but by the leaders we develop.

As the space domain grows in strategic importance, connecting the next generation of military leaders with the innovators shaping the industry has never been more important.

This week, we proudly welcomed cadets participating in the United States Air Force Academy's Azimuth Program. We appreciated the thoughtful questions, engaging discussions and shared passion for the future of space, technology and national security.

We look forward to continuing to support programs that provide future leaders with opportunities to explore the critical role space plays in our nation’s security, economy and future.

This month, we celebrate five years in business, but space and defense innovation isn’t new to us.

With decades of innovation tracing back to our @SierraNevCorp Space Systems heritage, we combine the agility of a standalone business with a proven track record unparalleled among emerging companies.

By the numbers, our legacy speaks for itself:
500 missions of space flight heritage
30+ years of hardware delivery across space systems, components, and mission-enabling technologies

We're proud of where we came from, but we're even more energized about how we’re leveraging our roots to impact the future of American dominance in space.

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 reminds us of the true cost of our freedom and the courage of those who gave everything to protect it.

In recognition of their service, our Veterans Affinity Group, has set up Fallen Comrade tables at our facilities as a symbol of our respect and remembrance, knowing that all gave some, but some gave all.

Today and every day, we honor their memory and remain grateful for their sacrifice.

Attending the @AIAA Ascend conference? We are too! Chris Nie will be there diving into all things lunar, while Christopher Allison will share his perspective on Next-Generation National Security Space during the "Edge of Tomorrow" panel, moderated by Clayton Swope.

We look forward to connecting with everyone in Washington DC.

We're proud to celebrate our team members—Drake Nimz, Todd Treichel, Trent Cybela, and Jared Ruzicka—who served as Rocket Judges at the NASA Wisconsin Space Grant Consortium’s Collegiate Rocket Launch (CRL) competition! As @AIAA Wisconsin Section volunteers, they evaluated student teams from critical design review all the way through launch.

By sharing their expertise, they’re helping the next generation of aerospace engineers gain hands-on experience in rocket design, construction, and flight.

We’re proud to welcome Retired U.S. Space Force Lt. Gen. John Shaw to Sierra Space’s board of directors. As chair of our Classified Business and Security Committee, Gen. Shaw brings more than 35 years of national security space and aerospace expertise. His leadership will help us advance our mission at the intersection of innovation and security in space.

Welcome, General Shaw!

Dream Chaser has successfully completed acoustic testing at @NASA's Kennedy Space Center's Space Systems Processing Facility.
 
The spacecraft successfully withstood the intense vibrations produced from sound waves during a rocket launch as it prepares for its first flight to Low Earth Orbit (LEO).
 
Acoustic testing at NASA’s SSPF utilized an array of 90 stacked speakers to simulate sound and airborne vibrations experienced during a rocket launch.
 
The successful test validated the durability of Dream Chaser’s critical electronic systems and confirmed the structural integrity of the spacecraft.

Last year, @NASA's PUNCH mission launched from Vandenberg Space Force Base. Since then, the mission's four small satellites have been observing the Sun's corona and its transition to the solar wind.

PUNCH continues to provide continuous 3D observations to better understand solar wind formation and its effects on the solar system.

We are proud to have provided the solar arrays for this mission.
