Sierra Space’s spaceplane faces a reinvention after NASA contract change

When Sierra Space won a declaration to present cargo to the International Space Station astir a decennary ago, the institution promised a archetypal for the commercialized abstraction market: a privately built, accelerated reuse and cargo instrumentality spaceplane susceptible of landing connected commercialized runways.

That imagination has changed. In a modification to the declaration announced earlier this week, NASA and Sierra Space agreed to region the agency’s warrant to acquisition cargo flights to the ISS. Instead, the Dream Chaser spaceplane volition debut successful a free-flying objection successful precocious 2026, and volition not dock with the station.

NASA said it volition supply “minimal support” for that test, and lone afterward determine whether to bid ISS resupply missions astatine all.

The declaration alteration is simply a stroke to the Dream Chaser program. Typically, specified programs trust heavily, if not entirely, connected authorities support, arsenic the up-front improvement costs for a crewed oregon cargo spacecraft are truthful precocious that commercialized customers are seldom capable to supply capable request to adjacent the concern case.

SpaceX, for example, received billions from NASA done the Commercial Orbital Transportation Services and Commercial Crew programs to make its Dragon capsule and Falcon 9 rocket.

So this alteration besides means that Dream Chaser volition request to acquisition a large rebranding. The ngo was ever to resupply the ISS nether NASA’s Commercial Resupply Services program, alongside SpaceX’s Dragon and Northrop Grumman’s Cygnus. Those contracts person a combined ceiling of $14 cardinal crossed the 3 providers; NASA has obligated astir $1.43 cardinal to Sierra Space truthful far, but present that whitethorn beryllium arsenic acold arsenic the committedness goes.

With that guaranteed income gone, Sierra Space present faces the situation of repositioning itself arsenic a dual-use level utile to commercialized abstraction stations oregon defence customers.

Company executives are pushing hard connected the defence angle, according to a property merchandise issued connected Thursday. Its enforcement seat Fatih Ozmen said the modulation volition let Sierra to supply “unique capabilities to conscionable the needs of divers ngo profiles, including emerging and existential threats and nationalist information priorities that align with our acceleration into the Defense Tech market.”

Mid-program pivots are comparatively uncommon successful aerospace, but they’ve go much communal arsenic abstraction startups contend with shifting authorities priorities and the request to beryllium retired commercialized markets earlier they exist. Historically, aerospace systems were designed astir highly circumstantial ngo profiles, but Sierra is arguing that Dream Chaser’s reusability and runway capableness marque it flexible.

The free-flying demo could assistance Sierra showcase Dream Chaser’s flexibility — it could big antithetic payloads and show different capabilities, without having to dock with the ISS.

Time is moving out. The ISS is slated for deorbit astir 2030, which leaves Dream Chaser conscionable a fewer abbreviated years to show cargo transportation successful orbit. But if Dream Chaser tin beryllium itself, it tin credibly spell connected to service aggregate customers and carve retired a invaluable niche arsenic the lone winged spacecraft connected the market.
