Expedition 59 Prepares to Launch to Station

At the Baikonur Cosmodrome in Kazakhstan, teams are making final preparations for the launch of NASA astronauts Nick Hague and Christina Koch, and cosmonaut Alexey Ovchinin of Roscosmos, to the International Space Station. Their journey to the station will begin with a lift off at 3:14 p.m. EDT (12:14 a.m. March 15 Kazakhstan time). Live launch coverage will begin at 2 p.m. on NASA Television and the agency’s website.

The trio’s arrival will return the orbiting laboratory’s population to six, including three NASA astronauts. This launch will also mark the fourth Expedition crew with two female astronauts. The three will join station commander Oleg Kononenko of Roscosmos, NASA astronaut Anne McClain, and David Saint-Jacques of the Canadian Space Agency. The new crew members will dock to the Rassvet module at 9:07 p.m. Expedition 59 will begin officially at the time of docking.

Hague and Ovchinin are completing a journey that was cut short Oct. 11, when a booster separation problem with their Soyuz rocket’s first stage triggered a launch abort two minutes into the flight. They landed safely a few minutes later, after reaching the fringes of space, and were reassigned to fly again after McClain, Kononenko and Saint-Jacques launched in early December. This will be Ovchinin’s third flight into space, the second for Hague and the first for Koch. Hague, Koch, and McClain are from NASA’s 2013 astronaut class, half of which were women—the highest percentage of female astronaut candidates ever selected for a class.

Housekeeping and Maintenance Punctuate Last Full Day of Expedition 58

The last full day of Expedition 58—before the launch, docking and consolidation of crews to become Expedition 59—was mostly spent on housekeeping items for the continued, successful operation of the International Space Station. 

NASA astronaut Anne McClain floated through the Tranquility and Zvezda service modules, deploying acoustic monitors. She paused in the U.S. lab at an EXPRESS rack to install communications gear and perform additional maintenance. David Saint-Jacques of the Canadian Space Agency also worked with EXPRESS today, moving Space Automated Bioproduct Labs from rack-1 to rack-2. This miniature laboratory within the larger orbiting laboratory supports life science research, hosting microorganisms (bacteria, yeast, algae, fungi, viruses, etc.), small organisms, animal cells, tissue cultures and small plants for evaluation in space.  

Expedition Commander Oleg Kononenko of Roscosmos replaced fuel bottles on the Combustion Integrated Rack, which allows the crew members to conduct fluids and combustion studies in microgravity. 

Today in Baikonur, Kazakhstan, NASA astronauts Nick Hague and Christina Koch, and cosmonaut Alexey Ovchinin of Roscosmos, were certified for flight by the Russian state commission and held their final news conference.  

Tomorrow, the soon-to-be station residents will hitch a ride aboard a Soyuz MS-12 for blastoff at 3:14 p.m. EDT on, coincidentally, 3/14. After a relatively speedy six-hour flight, the Soyuz is expected to dock to station’s Rassvet module at 9:07 p.m. Expedition 59 will begin officially at the time of docking. 

The events will unfold live on NASA TV, with launch coverage beginning at 2 p.m. and docking coverage at 8:15 p.m., respectively. After a brief break, tune in at 10:30 p.m. for the hatch opening and welcome, which will return the orbiting laboratory’s population to six—including three NASA astronauts. And, just in time for Women’s History Month, this launch marks the fourth Expedition crew with two female astronauts.
