A spaceship bankrolled by British tycoon Sir Richard Branson made its first powered flight Monday in a test that moves Virgin Galactic toward its goal of flying into space later this year.

While SpaceShipTwo did not break out of the atmosphere during the test flight, it marked a significant milestone for Virgin Galactic, which intends to take passengers on suborbital joyrides.

During the early morning flight, SpaceShipTwo, strapped beneath a twin-fuselage jet, took off from an airport runway in the Mojave Desert north of Los Angeles. The jet released SpaceShipTwo, which ignited its engine for 16 seconds, then glided to a safe landing.

Until now, SpaceShipTwo has only performed unpowered glide flights. Several powered flights are planned this summer, culminating with a dash into space targeted toward the end of the year.
