The engineers working to recover Stereo-B, the solar observatory that was lost for 22 months, have released an update on the spacecraft’s condition.
In the subsequent days, analysis revealed the spacecraft was in a complex spin, with its fuel tanks frozen and the battery state of charge at 30%. The prime goal is now to fully recover battery power and gradually thaw STEREO-B’s instruments and fuel tanks from its deep freeze. It may be clear that the spacecraft is still in a critical condition and that it will take quite some time before imagery, such as those from its twin STEREO-A, will be available again.
