After lifting off from NASA's Kennedy Space Center on Thursday, July 31, the crew members of NASA's SpaceX Crew-11 mission are arriving at the International Space Station. NASA astronauts Zena Cardman and Mike Fincke, JAXA (Japan Aerospace Exploration Agency) astronaut Kimiya Yui, and Roscosmos cosmonaut Oleg Platonov are scheduled to dock in their SpaceX Dragon spacecraft at approximately 2:30 a.m. EDT (0630 UTC) on Saturday, Aug. 2. Station crew will then open the hatches between Dragon and the station, to be followed by a welcome ceremony. Cardman, Fincke, Yui, and Platonov will spend several months on the station, conducting research to help humans learn how to live in space while making life better on Earth. After Crew-11 arrives at the station, the four members of Crew-10 will depart the station following a brief handover period.

Get to know the story of Antigone, daughter of Oedipus, who was determined to give her slain brother Polyneices a proper burial. -- The gods watched as Oedipus’ daughter, Antigone, stole out of the palace in Thebes the morning after a devastating battle. Antigone was on a dangerous mission to do what she felt was right, though it meant risking her life. She sought to abide by divine law and honor her late brother Polyneices through burial— but the king had other plans. Stephen Esposito shares the tragic Greek tale of Antigone.
