Space Launches For This Week
Space Flight Now Launch Schedule
TBD Eris • TestFlight1
Launch time: Window opens 7:30 a.m. AEST on May 16 (5:30 p.m. EDT, 2130 UTC on May 15)
Launch site: Pad 1, Bowen Orbital Spaceport
Gilmour Space in Australia is preparing to launch the inaugural flight of its Eris Block 1 rocket. The three-stage launch vehicle is 25 m (82 ft) tall and is equipped with 1.5 m (4.9 ft) diameter payload fairings. The rocket is designed to send up to 305 kg up to low Earth orbit. This first mission, called “TestFlight1,” does not appear to have a payload on board. Delayed from May 4, 2024, due to a lack of launch permit. Delayed from May 14/15 due to a ground support system issue. Delayed from May 15/16 due to unintended triggering of the payload fairing deployment at the pad.

NET Late May Falcon 9 • GPS 3 SV-08
Launch time: TBD
Launch site: SLC-40, Cape Canaveral Space Force Station, Florida
A SpaceX Falcon 9 rocket will launch the eighth Global Positioning System (GPS) 3 satellite, built by Lockheed Martin. The GPS 3 Space Vehicle 08 (SV-08) is named in honor of mathematician, Katherine Johnson, whose calculations contributed significantly to early human spaceflight. The Falcon 9 first stage booster will target a landing on a droneship positioned in the Atlantic Ocean.

June 8 Falcon 9 • Axiom Mission 4 (Ax-4)
Launch time: 9:11 a.m. EDT (1311 UTC)
Launch site: Launch Complex 39A, Kennedy Space Center, Florida
A SpaceX Falcon 9 rocket will launch the fourth private astronaut mission to the International Space Station. Former NASA astronaut and Axiom Space’s Director of Human Spaceflight will serve as the commander of the mission. This will be her fifth trip to space and her second time commanding a private astronaut mission. Shubhanshu Shukla, an Indian Air Force (IAF) pilot and astronaut with the Indian Space Research Organisation (ISRO) will be the pilot onboard the SpaceX Crew Dragon. Sławosz Uznański-Wiśniewski, a Polish member of the European Space Agency’s (ESA) Astronaut Reserve Class of 2022, and Tibor Kapu, a Hungarian member of the Hungarian to Orbit (HUNOR) Astronaut Program, will serve as the Mission Specialists. These four astronauts will spend up to 14 days docked to the ISS after launching from NASA’s Kennedy Space Center on a Falcon 9 rocket. Following stage separation, the booster will target a touchdown at Landing Zone 1 (LZ-1) at Cape Canaveral Space Force Station.

NET June 23/24 H-2A • GOSAT-GW
Launch time: 1:33:03 a.m. JST on June 24 (12:33:03 p.m. EDT, 1633:03 UTC on June 23)
Launch site: Launch Pad 1, Tanegashima Space Center, Japan
A Mitsubishi Heavy Industries Co., Ltd. H-2A rocket will launch the Global Observing SATellite for Greenhouse gases and Water cycle (GOSAT-GW), a Japanese Earth-observing satellite. The roughly 2,900 kg (6,393 lbs) satellite will operate in a Sun-synchronous orbit at an altitude of 666 km (414 mi). This spacecraft comes from a partnership between the Japanese Ministry of Environment (MOE), National Institute for Environmental Studies (NIES) and the Japanese Aerospace Exploration Agency (JAXA). The two primary instruments are the Total Anthropogenic and Natural emissions mapping SpectrOmeter-3 (TANSO-3) and the Advanced Microwave Scanning Radiometer 3 (AMSR3). This will be the 50th and final launch of a H-2A rocket.

NET June Falcon 9 • Transporter-14
Launch time: TBD
Launch site: SLC-4E, Vandenberg Space Force Base, California
A SpaceX Falcon 9 rocket will launch dozens of payloads on its latest Smallsat rideshare program, called Transporter. This mission, dubbed Transporter-14, will include a variety of customers, including the MayaSat-1 capsule from The Exploration Company, the OSSIE OTV (orbital transfer vehicle) from UARX Space and three Erminaz PocketQubes from AMSAT-DL. The Falcon 9 first stage booster will perform a return to landing site touchdown at Landing Zone 4 less than eight minutes after liftoff.

Summer 2025 Falcon 9 • TRACERS
Launch time: TBD
Launch site: SLC-4E, Vandenberg Space Force Base, California
A SpaceX Falcon 9 rocket will launch NASA’s TRACERS (Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites) as the primary payload on a rideshare mission secured through the agency’s VADR (Venture-Class Acquisition of Dedicated and Rideshare) launch services contract, providing new opportunities for science and technology payloads. The two TRACERS satellites are designed to study the interaction of the Sun’s solar particles interact with the Earth’s magnetic field to better understand the impacts of solar activity on Earth. The mission is conducted through a partnership between NASA; the University of Iowa; the Southwest Research Institute; the University of New Hampshire; the Space Sciences Laboratory at the University of California, Berkeley; and the University of California, Los Angeles. The secondary payload(s) have not been announced for this mission as of May 15.
