Scientists have leveraged the @Space_Station’s microgravity environment to better understand and treat different types of cancers. Microgravity can impact cell growth, function, and gene expression unlocking new ways to study cancer-related cells in ways not possible on Earth.

One for the books. 👨‍🚀🛰 The first spacewalk to assemble the space station was underway 25 years ago today. Astronauts James Newman and Jerry Ross mated 40 cables and connectors between the Unity and Zarya modules during a seven-hour, 21-minute excursion.

U.S. media can apply for credentials to cover the launch of Northrop Grumman’s 20th commercial resupply mission to the station, targeted no earlier than Monday, Jan. 29. The deadline to apply is Friday, Jan. 12 at 11:59pm ET. More... go.nasa.gov/489bbNt

Throughout the 12-day mission, Ross and Newman conducted three spacewalks to assist assembly. Four days after mating, the station opened for the first time, welcoming the crew aboard and setting the pace for a future of living and working in low-Earth orbit.

Carried by Endeavour, Unity launched into orbit during the first Space Shuttle mission to the station, along with astronauts Nancy Currie, Jerry Ross, Robert Cabana, Frederick Sturckow, James Newman and cosmonaut Sergei Krikalev.

25 years of remarkable achievements. On Dec. 6, 1998, the six-member STS-88 crew mated Unity, the first U.S. element of the International Space Station, with the already-orbiting Zarya module, beginning the historic assembly of the orbiting laboratory.

The first @Space_Station construction mission lifted off 25 years ago today! Space Shuttle Endeavour launched at 3:35 AM EST #OTD in 1998, bringing the Unity module, America's first piece of the International Space Station. Learn more about STS-88: go.nasa.gov/3sMOvDL

Worldwide cooperation. The International Space Station is the world’s premiere orbital laboratory and represents the work of people and organizations representing 15 nations. The worldwide team works daily to operate and upgrade its capabilities.

Peer back in time as we celebrate 25 years of space station assembly this week. 🛰 #OTD in 1998, Space Shuttle Endeavour launched with Unity—the first U.S. element of the station—along with a crew of six, to begin assembly of the orbital lab during a 12-day mission.

The Progress 86 cargo craft successfully docked to the station’s Poisk module at 6:18am ET this morning, delivering nearly three tons of food, fuel, and supplies for the Exp 70 crew. blogs.nasa.gov/spacestation/2…
