Mission Details
TRACERS
NASA's Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites (TRACERS) mission, consisting of two identical satellites that will orbit Earth in tandem (one following the other), will help understand magnetic reconnection and its effects in Earth's atmosphere. Magnetic reconnection occurs when activity from the Sun interacts with Earth's magnetic field. By understanding this process, scientists will be able to better understand and prepare for impacts of solar activity on Earth.

NASA Sun & Space  @NASASun
NASA's TRACERS spacecraft have arrived at Vandenberg Space Force Base in California. Next destination: space! 🚀
 
TRACERS (Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites) are a pair of spacecraft that will orbit Earth to study magnetic reconnection — those sudden, spark-like moments when Earth's magnetic field links up with the Sun's. During reconnection events, solar particles and energy pour into our atmosphere, providing the power that ignites auroras and drives space weather on Earth.

Bard (PExT Demo)
Bard will flight-demonstrate the Polylingual Experimental Terminal (PExT), an advanced communications technology developed in collaboration with the Johns Hopkins Applied Physics Laboratory (APL) and NASA's SCaN (Space Communications and Navigation) Program. The terminal is designed to enable real-time interoperability between government and commercial satellite relay networks—a first-of-its-kind capability as NASA shifts toward a commercial satellite relay communications architecture.

Athena EPIC
NASA, the U.S. Space Force, NOAA, and NovaWurks have strategically aligned efforts to gain wisdom from Athena EPIC (Economical Payload Integration Cost) — a SmallSat that will demonstrate the ability of NovaWurks SensorCraft architecture to support future missions. Athena serves as a pilot opportunity for transformational activities by pathfinding an innovative space vehicle architecture, learning from commercial best practices, implementing a whole-of-government approach, and reducing schedule to launch as well as lifecycle costs. The instrument will be a simplified and lighter version of the CERES (Clouds and the Earth Radiant Energy System) instrument.

REAL
Realistic Electron Atmospheric Loss (REAL) is a scientific investigation mission designed to characterize the loss of particles from Earth's Van Allen radiation belts. REAL will carry an energetic particle instrument that is sensitive to both electrons and protons. From its vantage point in low-Earth orbit, REAL will point its instrument along Earth's magnetic field to measure radiation belt particles as they enter the atmosphere.

SpaceX is targeting Tuesday, July 22 for Falcon 9's launch of NASA's TRACERS mission from Space Launch Complex 4 East (SLC-4E) at Vandenberg Space Force Base in California. The 57-minute launch window opens at 11:13 a.m. PT. If needed, a backup opportunity is available on Wednesday, July 23 at the same time.

Also on board this mission is SEOPS' Epic Athena, Skykraft's Skykraft 4, Maverick Space Systems' REAL, Tyvak's LIDE, and York Space Systems' Bard.

A live webcast of this mission will begin about 15 minutes prior to liftoff, which you can watch here and on X @SpaceX. You can also watch the webcast on the new X TV app.

This is the 16th flight for the first stage booster supporting this mission, which previously launched Crew-7, CRS-29, PACE, Transporter-10, EarthCARE, NROL-186, Transporter-13, and eight Starlink missions. Following stage separation, the first stage will land on Landing Zone 4 (LZ-4) at Vandenberg Space Force Base...
