Ince November 2020, $\text{VEN} \mu \mathrm{S}$ has begun the second phase of its mission. Indeed, $\text{VEN} \mu \mathrm{S}$ being dedicated to two different missions, the lifetime is separated in several phases. As the first phase, called VM1, ended few months ago, the radiometric performances statement can now be established. Firstly, this article briefly presents the $\text{VEN} \mu \mathrm{S}$ mission with the main system and technical features. Then, it summarizes the different phases of the $\text{VEN} \mu \mathrm{S}$ mission with a specific focus on the VM1 phase. Finally, there is an assessment of the radiometric performances (absolute calibration, dark signal, equalization, SNR and cloud mask) of $\text{VEN} \mu \mathrm{S}$ by focusing on important changes during the VM1 phase.
