Kennedy Space Center Director Bob Cabana was there when the ISS build began

At any given time as we’re sitting in traffic or walking the dog, astronauts are working and living above us.

This Oct. 31 marks the 20th year humans have been living in space. That means most college students today have never known a day without an astronaut orbiting above them on the International Space Station.

The International Space Station, or ISS, is just shy of the same length as an American football field and the largest spacecraft ever built.

Its construction was a collaboration between 16 different countries and today spacecraft from three countries can dock at the orbiting facility. The space station is a floating six-bedroom home for astronauts and doubles as an orbiting laboratory with hundreds of experiments ongoing at one time from growing vegetables in space and to research involving mice and flies.

For the very first episode of WKMG-TV and Graham Media’s new podcast, Space Curious, we go back to the beginning and learn how the International Space Station came to be with someone who was there at the beginning: Kennedy Space Center Director and former astronaut Robert “Bob” Cabana.

Before he led the Kennedy Space Center, Cabana was an astronaut and flew on four space shuttle missions, including as the commander of the first space station assembly mission.

On Dec. 4, 1998, Cabana, along with four other NASA astronauts and Russian Cosmonaut Sergei Krikalev, launched from Kennedy Space to mate the U.S.-built module, Unity, to the Russian pieces of the ISS, Zarya. The two pieces were created on opposite sides of the world but Cabana and his crew were tasked with connecting the two pieces 200 miles above Earth.

“It just went flawlessly. It sets a stage for the whole space station, assembly sequence, having that first mission go so well,” Cabana said.

The astronauts were also the first to go inside the ISS, but who would get to float through the hatch first was a surprise until the time came.

“When it came time to go inside, I didn’t tell anybody who was going to be first and the media kept asking and I wouldn’t tell. I didn’t even tell the crew,” Cabana said. “I felt as an International Space Station, we needed to enter as an international crew.”

Cabana and Krikalev went into the ISS at the same time.

“Sergei and I enter side by side, so there was no first person to enter the International Space Station,” Cabana said.

Construction and assembly of the space station would take a total of 13 years. Since Halloween in 2000, astronauts have continuously lived on the ISS.
