US-based microsatellite space platform enterprise Vector Space Systems has completed testing of the company’s second stage engine for its launch vehicle at Mojave, California.

The company is expecting to start sub-orbital test flight later this year with large-scale sub-orbital test flights planned for next year, and orbital launches scheduled for 2018.

During the test, the engine used 3D printed components and produced 500lb of thrust with a high-specific impulse for maximum fuel efficiency.

"The rapidity and success of this test sets the standard for the swift development of our launch vehicle."

The latest test is one in a series of second-stage engine tests leading to the launch vehicle’s flight qualification next year.

Officially announced this month, Vector Space Systems is comprised space industry veterans from SpaceX, Virgin Galactic, McDonnell Douglas and Sea Launch and is aiming to connect space start-ups with affordable and reliable frequent launch-enabling platforms and vehicles.

Vector Space Systems co-founder and CEO Jim Cantrell said: "Led by Vector CTO, John Garvey, the Vector propulsion team has made tremendous progress in a very rapid manner, building and successfully testing an engine using 3D printed components within two months of the company’s founding.

"The rapidity and success of this test sets the standard for the swift development of our launch vehicle and furthers our mission to revolutionise the way commerce accesses and utilises space."

The company has noted that it will continue to conduct tests of its first and second-stage engines, the mobile launch platform, and is producing full-scale vehicle engineering models.

Last month, the company had secured investments of more than $1m from a group of angel investors to develop frequent launch platforms for the microsatellite industry.
