Is there room for launch companies smaller than the United Launch Alliance and SpaceX?

Vector Space Systems successfully launched a full-scale model of its Vector-R rocket on Wednesday in Mojave, California. The test flight, which remained under 50,000 feet for regulatory purposes, allows the company to remain on track to begin providing launch services for small satellites in 2018, said Jim Cantrell, the company's chief executive and cofounder.

The Arizona-based rocket company is one of a handful of competitors racing to the launch pad to provide lower-cost access to space for small satellites. These satellites are generally under 500kg in mass and often much smaller (the industry trend is toward smaller, lighter, more capable satellites). The Vector-R rocket will eventually be capable of launching a payload of up to 45kg to an orbit of 800km above the Earth. Other companies trying to reach this market include US-based Virgin Orbit and New Zealand-based Rocket Lab. Neither company has begun commercial launches.

[...] The market seems ready for micro-launchers. For now, smaller payloads must typically "share" rides to space on larger rockets, and they cannot count on a launch date. Instead of being treated as excess cargo, Vector intends to offer these small satellites the capability to launch within three months of demand. Vector will launch these small payloads into any desired orbit from Kodiak Launch Complex in Alaska or Cape Canaveral in Florida. Launch costs will range from $2 million to $3 million.
