Astra Space is targeting early 2027 for the first flight of Rocket 4, giving the California launch company a new timetable for its long-planned return to orbit.

The schedule represents another reset for a program that had previously aimed for a 2026 test flight. Recent reporting from Ars Technica and SpaceNews places the maiden launch in early 2027, while launch-tracking services currently list the mission for the first quarter of 2027 from Wallops Flight Facility in Virginia.

Rocket 4 Is Astra Space’s Comeback Vehicle

Rocket 4 is an expendable two-stage liquid-fueled rocket. Astra lists a target payload capacity of one metric tonne to mid-inclination low Earth orbit over the vehicle’s lifecycle and a long-term target of weekly launches, subject to spaceport availability.

The vehicle is about 18.9 meters tall and 1.8 meters in diameter. Astra’s architecture emphasizes manufacturability and mobile launch operations rather than first-stage reuse. The company says the system is intended to operate from multiple spaceports with comparatively limited permanent infrastructure.

A Different Bet on Launch Economics

Astra’s approach stands apart from companies investing heavily in reusable launch vehicles. Chief executive Chris Kemp has described Rocket 4 as a comparatively simple, inexpensive expendable system that Astra hopes to manufacture at high volume.

The strategy is ambitious. Astra’s previous Rocket 3 program reached orbit successfully twice but also suffered multiple launch failures. The company stopped flying that vehicle and later went private in 2024. Rocket 4 therefore has to demonstrate both technical reliability and a sustainable business model.

Defense Demand Could Matter

Responsive launch is also becoming a national-security market. The U.S. Department of Defense previously awarded Astra work supporting Rocket 4 development, including a Defense Innovation Unit contract with a ceiling of up to $44 million to advance tactically responsive launch capabilities.

Astra argues that a containerized, mobile launch system could give government and commercial customers more flexibility over where rockets are deployed. That proposition will ultimately depend on Rocket 4 completing its test program and returning Astra Space to orbit.

The Next Test Is the Launch Pad

The early-2027 date remains a target rather than a guaranteed launch date. Rocket development schedules can move as engines, stages, ground systems and regulatory work progress. But Astra Space now has a clearly defined vehicle, a current launch window and a market that is actively looking for additional orbital capacity.
