The reboost provided by ATV’s thrusters and planned for tomorrow, 18 March, is now set for 2.2 m/second – meaning the International Space Station will increase its orbital speed by this amount. This is a little fast, but still slower than a typical walking speed. This boost will also increase the ISS altitude by about 4 km (it’s now at 360.8 km). The burn will use about 340 kg of fuel. More details to follow.
