Science with SOIR

Since its arrival at Venus, SOIR has been fully operational and has already delivered high-quality scientific data and results.

As SOIR is a high-resolution spectrometer operating in the infrared region (2.2-4.3 µm), it can detect several species of high interest to understand the Venus atmosphere, such as its main constituent CO₂, but also some key trace gases, such as CO, H₂O/HDO, HCl, or HF.
