Two astronauts will exit the International Space Station on Tuesday and conduct a spacewalk to finish installing a high-speed space-to-ground antenna. The duo completed final spacewalk preparations on Monday with two of their Expedition 75 crewmates while the rest of the orbital residents studied the human respiratory system, activated Earth observation gear, and packed a cargo spacecraft prior to its departure.
