Emirati astronaut Sultan Al Neyadi tweeted on his account: "Tomorrow, my colleague Stephen Bowen and I will exit the International Space Station for a new mission to ensure the station's sustainability by changing the RFG unit for radio frequencies and preparing for the installation of solar panels. After long and challenging training, we are ready and our morale is high to take on the challenge in this mission. Tomorrow we have a new appointment with Zayed's ambition."
