Okay, so SpaceX did it again! The Crew-12 mission, which is their 20th human spaceflight, blasted off from Cape Canaveral, Florida, way back on February 13th at 5:15 AM. If you missed it, don't worry, 'cause the coolest part is about to happen: docking with the International Space Station (ISS).

These brave space travelers are expected to link up with the ISS today, February 14th, around 3:15 PM. And guess what? You can actually watch it live! It's pretty amazing to think that their Dragon capsule will have traveled for roughly 34 hours since it left Earth.

Who's on board this time? We've got NASA astronauts Jessica Meir and Jack Hathaway, the European Space Agency's Sophie Adenot, and Roscosmos cosmonaut Andrey Fedyaev. They're joining the existing crew of three on the ISS, especially considering that Crew-11 had to cut their mission short a month ago. Remember that? It seems that NASA decided to bring them home early because one of the crew members faced a health problem that they couldn't quite figure out with the ISS's equipment. I think it was a safe call; better to be cautious, right?

Crew-12 is settling in for a good eight months up there on the ISS. And they won't be twiddling their thumbs. They've got a whole bunch of science experiments planned. Some of these experiments are focused on human health, while others are geared towards developing new technologies for future trips to the Moon and even Mars. For example, they'll be studying how pneumonia-causing bacteria can lead to long-term heart problems. It sounds pretty scary!

They will also investigate how your physical characteristics can affect blood flow during spaceflight. It's amazing how much we still need to learn about the human body in space.

If you're eager to catch the docking, NASA's live coverage starts at 1:15 PM. I know I'll be tuning in. It's always inspiring to see these missions unfold and think about what they mean for our future in space.
