Explorer1Mission

Explorer1Mission is a space research program developed by the Space Research Alliance to study the near-Earth environment and to demonstrate compact satellite technologies for future multi-instrument missions. The program envisions a small, bus-sized spacecraft in low Earth orbit designed to operate for at least two years and to provide continuous measurements of the magnetosphere, radiation environment, and solar-wind interactions with the upper atmosphere. The mission's primary objectives are to map the inner Van Allen belts, characterize plasma populations in the plasmasphere, and test autonomous fault management and crosslink communication in a small-satellite platform.

The spacecraft, Explorer1, uses a modular bus with solar electric propulsion as an optional power-and-control system. Instruments include a magnetometer to measure magnetic fields; ion and electron spectrometers for particle populations; a dosimeter to monitor radiation exposure; a Langmuir probe for plasma density; a small camera for calibration targets; and a high-rate data transmitter for downlink. The mission plan emphasizes low-cost procurement, rapid integration, and open data access to foster academic and international collaboration.

Launch and operations: The mission would launch aboard a dedicated small launch vehicle into a sun-synchronous or low Earth orbit, with ground stations providing near real-time data. Scientific results would support space weather research, instrument technology development, and planning for subsequent explorers in cislunar or deep-space contexts.

As of the latest planning stage, Explorer1Mission remains in concept development with active partner involvement and is subject to funding and programmatic approvals.
