STROBE-X combines the two highest priority sustaining activities from the 2020 Astrophysics Decadal Survey into one powerful mission: “a space-based time-domain and multi-messenger program” and “a new line of probe missions ... identified as important to accomplish the survey's scientific goals.”

STROBE-X:

• Is a time domain and multi-messenger mission
• Is an unparalleled laboratory for probing strong gravity and the behavior of matter in extreme environments
• Routinely discovers rare transients through its wide field of view
• Conducts over 10,000 broad energy band pointed X-ray spectroscopic observations every year
• Answers high priority science questions in NASA's Strategic Objectives and Decadal Survey

STROBE-X will provide transformative science including:

• Multi-Messenger
• Strong Gravity
• Dense Matter
• Accretion Flows
• Time Domain Astrophysics
