Supersonic. Mach 1.21.
Quarterhorse Mk 2.1 is now the world’s first privately developed, unmanned supersonic jet and the fastest unmanned aircraft flying today.
This flight makes Hermeus the fastest company in aviation history to go from founding to supersonic flight - exactly 364 days after the maiden flight of our first aircraft.
Now, we fly faster.
A special thanks to @DIU_x, Director @OwenWest91, Maj. Gen. Joe "Solo" Kunkel, and Deputy Director Kyle Norman.
Overheard at Wallops: "That's a big plane!"
Wallops' teams supported the arrival of an Antonov AN-124, the heaviest operating cargo aircraft in the world, carrying cargo for a commercial customer.
Starship’s twelfth flight test will debut the next generation Starship and Super Heavy vehicles, powered by the next evolution of the Raptor engine and launching from a newly designed pad at Starbase. The launch is targeted as early as Tuesday, May 19 → https://t.co/2gZQUxS6mm
Three years since the first flight of Starship, the next generation is here. New ship. New booster. New engines. New pad and new test site. SpaceX engineers are working to solve one of the most difficult engineering challenges in history: developing a fully, rapidly reusable rocket
Celebrating 36 years of discovery with the Hubble Space Telescope 🔭
Collected on April 23, 2026, by one of Vantor's WorldView Legion satellites, this remarkable non-Earth image showcases Hubble from just 61.8 km away—an incredible perspective of one of humanity’s most iconic scientific instruments. With a space sample distance of 4.0 cm, Hubble’s signature cylindrical body, gleaming thermal shielding, and extended solar arrays are clearly visible, along with the open aperture door at the front of the telescope.
For over three decades, Hubble has expanded our understanding of the universe—delivering breathtaking imagery and groundbreaking science that continue to inspire.
Proud to support the technologies and teams that make moments like this possible.
Wheels up for Quarterhorse.
On its latest flight, Mk 2.1 successfully deployed and retracted its landing gear, validating a critical system and helping the aircraft reach higher speeds.
We’re not slowing down. Stay tuned.
Only one chance in this lifetime…
Like watching sunset at the beach from the most foreign seat in the cosmos, I couldn’t resist a cell phone video of Earthset. You can hear the shutter on the Nikon as @Astro_Christina is hammering away on 3-shot brackets and capturing those exceptional Earthset photos through the 400mm lens. @AstroVicGlover was in window 3 watching with @Astro_Jeremy next to him.
I could barely see the Moon through the docking hatch window but the iPhone was the perfect size to catch the view…this is uncropped, uncut with 8x zoom which is quite comparable to the view of the human eye. Enjoy.
Quarterhorse Mk 2.1 has received authorization from the Federal Aviation Administration to exceed Mach 1 speeds.
Hermeus is the second company ever authorized by the FAA to fly a civil aircraft supersonic and the first to do so with an unmanned system.
We’re grateful for a strong partnership with the agency and proud to be a part of aviation history.
