ALMA is very pleased to share the positive news that science observations re-started on 17 March 2021. These were the first scientific data to be acquired since the Observatory shutdown, due to the Covid-19 pandemic, in March 2020. The first newly-acquired datasets have now been calibrated and imaged, and have successfully passed the ALMA quality assurance stages. They will shortly be delivered to our users worldwide. At present, science observations are being taken on the 12-m Array only. Science observations will start on the 7-m Array when eight 7-m antennas are available.
