Spaceflight, Maritime Launch Agree to Future Sherpa OTV Missions


Reading time ( words)

Spaceflight Inc., a premier launch and in-space transportation services provider, announced today it signed an agreement with Maritime Launch Services Inc. to launch up to five of its Sherpa Orbital Transfer Vehicles (OTVs). The launches will be from Spaceport Nova Scotia aboard the Cyclone-4M beginning in 2025.

Spaceflight has successfully delivered more than 550 spacecraft across 55 launches, including both rideshare and dedicated launches, on a wide variety of launch vehicles. This includes launching five Sherpa OTVs, which carried more than 50 payloads to space.

“We’re eager to expand our portfolio of launch vehicle partners to carry our Sherpa OTVs to space. Maritime Launch represents an exciting new option as the first vehicle partner to launch from a commercial spaceport in North America,” said Curt Blake, CEO and president of Spaceflight Inc. “Not only does the Cyclone-4M deliver a wide variety of desirable inclinations for our customers, but the pricing is very attractive. The agreements to transport our Sherpa OTVs are foundational in our continuing efforts to expand our OTV capabilities from last-mile delivery to in-orbit servicing.”

Maritime Launch is developing North America’s first commercial spaceport, Spaceport Nova Scotia, near Canso, Nova Scotia. The company will launch the Cyclone-4M, a medium class launch vehicle with a payload capability of five tons to low Earth orbit. Satellite companies can rely on the vehicle components’ flight heritage, demonstrated by several operators globally, boasting approximately 878 successful launches.

“We are thrilled to have Spaceflight aboard our Cyclone-4M launches starting in 2025,” says Stephen Matier, president and CEO of Maritime Launch. “Spaceflight is a global leader with unmatched experience in mission management and payload integration. Our partnership will increase our launch offerings and provide our clients with innovative, last-mile delivery of their payload to orbit.”

Launch of the Sherpa OTVs for rideshare customers on Cyclone-4M will accommodate CubeSats, smallsats, and large form-factor customer vehicles. In 2022, Spaceflight successfully launched both its experimental OTVs – Sherpa-AC for hosted payloads, and Sherpa-LTC, which features chemical propulsion. The company is also underway preparing for the launch of the next variation in its Sherpa OTV program – Sherpa-ES, a higher energy variant with a bipropellant, high delta-V OTV that enables smallsat delivery anywhere in cislunar space.

A Challenge Facing Aerospace Designers In 2023

01/24/2023 | Lee Ritchey, Speeding Edge
As the aerospace industry has been tasked with fitting increasingly complex electronics in existing airframes the demands on PCB substrates have begun to overtask the existing state of the art in PCB fabrication. Recently, I was called in to troubleshoot some reliability problems with a very dense PCB that had components on both sides and required the use of stacked blind vias and buried vias. The usual name for this kind of design is “build-up fabrication,” requiring many trips through the lamination, drilling, and plating operations at a fabricator.

Durability and Cost Benefits Drive Mil-Aero Demand for OCPP

01/17/2023 | Sam Sadri, QP Technologies
Ceramic packages were, for many years, the option of choice for semiconductor prototype assembly, particularly in military-aerospace applications. They can withstand high temperatures and can be hermetically sealed. However, they can be costly and, while they allow for rapid assembly of first samples, the final product is typically a plastic package, so the ceramic prototype doesn’t offer an accurate representation. This need for a better, more viable alternative to ceramic was one of the catalysts that gave rise to open-cavity plastic packaging (OCPP).

US, Japan Sign Space Collaboration Agreement at NASA Headquarters
