NET April 16 New Glenn • BlueBird 7

Launch time: TBD

Launch site: Launch Complex 36, Cape Canaveral Space Force Station

A Blue Origin New Glenn rocket will launch AST SpaceMobile’s BlueBird 7satellite into low Earth orbit. This is the second satellite in AST SpaceMobile’s next-generation satellite constellation and is designed to support space-based cellular broadband for commercial and government customers. This will be the third launch of a New Glenn rocket to date. As of Jan. 22, Blue Origin hasn’t stated if it intends to attempt a booster recovery on this mission.

NET April Vega-C • Smile

Launch time: TBA

Launch site: ZLV pad, Europe’s Spaceport, Kourou, French Guiana

An Avio Vega-C rocket will launch the Smile mission, a collaboration between the European Space Agency (ESA) and the Chinese Academy of Sciences (CAS). The Smile (Solar wind Magnetosphere Ionosphere Link Explorer) is set to deploy from the rocket 57 minutes after liftoff and deploy its solar arrays within 10 minutes after that. It has a planned mission life of three years and will operate in a highly elliptical Earth orbit. According to ESA, “Smile will use four science instruments to study how Earth responds to the solar wind from the Sun. This will improve our understanding of solar storms, geomagnetic storms and the science of space weather.”

NET July 5, 2028 Falcon Heavy • Dragonfly

Launch time: TBD

Launch site: Launch Complex 39A, Kennedy Space Center, Florida

A SpaceX Falcon Heavy rocket will launch NASA’s Dragonfly mission, which consists of a rotorcraft designed by the Johns Hopkins Applied Physics Laboratory (APL) that will explore Saturn’s icy moon, Titan. The mission was originally selected in 2019 and went through multiple plan iterations across fiscal years 2020 through 2022. It passed its Preliminary Design Review in March 2023 and then its Critical Design Review in April 2025. The mission has a total lifecycle cost of $3.35 billion, of which, $256.6 million was awarded to SpaceX to provide launch services and other mission related costs. The 20-day launch window opens on July 5, 2028.
