Mird-226 -

The MIRD-226 was the second satellite in the MIRD (Multimission Infrared Detector) series, which was designed to test the feasibility of using infrared sensors for reconnaissance missions. The first MIRD satellite, launched in 1964, was a prototype that demonstrated the potential of infrared technology for gathering intelligence. Building on the success of the first MIRD, the MIRD-226 was developed with a more advanced sensor system and improved resolution.

Based on published third-party evaluations (e.g., university extension trials, 2023–2025): MIRD-226

| Application Area | Purpose | |----------------|---------| | Row crop herbicide | Improve weed coverage; reduce volatilization loss | | Fungicide on broadleaf crops | Enhance retention on vertical or angled leaves | | Insecticide on dense canopies | Penetrate middle/lower leaf layers | | Defoliant (e.g., cotton) | Uniform coverage for even leaf drop | | Foliar nutrient spray | Prevent runoff; increase absorption efficiency | The MIRD-226 was the second satellite in the

By promoting a standardized approach to dosimetry, MIRD-226 aims to enhance consistency across different centers and studies. This uniformity is vital for comparing outcomes and ensuring that patients receive optimal care. Based on published third-party evaluations (e

MIRD-226 is not classified as a restricted-use pesticide. In the United States, it is typically registered as an (not a pesticide active ingredient) and therefore does not require an EPA pesticide registration number. However, it must comply with EPA inert ingredient regulations (40 CFR 180.910–960). Users should verify state-level adjuvant approval lists (e.g., California DPR, Texas A&M) before use.

By providing more accurate dosimetry, MIRD-226 helps minimize radiation exposure to non-target tissues, reducing the risk of radiation-induced side effects.

The MIRD-226 was launched on February 27, 1969, from the Vandenberg Air Force Base in California, using a Thor-MSLV-2 rocket. The satellite was placed into a sun-synchronous orbit at an altitude of approximately 600 kilometers (373 miles).
