Watch the NASA SpaceX Crew-12 mission dock with the ISS

The four spacefarers are joining the three remaining passengers onboard the ISS after Crew-11 flew back to Earth a month earlier than planned. If you’ll recall, NASA made the decision to cut their mission short after one of the crew members had a medical issue that instruments on the ISS aren’t capable of diagnosing. While the crew member was stable, the agency decided to bring the whole mission home out of an abundance of caution.
Crew-12 will be staying on the ISS for eight months and will conduct a number of scientific experiments, including ones related to human health and ones meant to advance technologies for future missions to the moon and Mars. They will study how pneumonia-causing bacteria can lead to long-term heart damage, for instance, and will also look into how a person’s physical characteristics can affect blood flow during spaceflight. NASA’s live coverage for the docking starts at 1:15 PM.
