CAPE CANAVERAL, Fla. (AP) — The astronauts who will depart the International Space Station as early as this weekend will be stuck using diapers on the way home.

That's because the toilet in their SpaceX capsule is broken.

NASA astronaut Megan McArthur told reporters Friday that it's just one of many challenges she and the others faced during their six-month mission.

NASA is deciding whether to bring McArthur and her three crewmates back before launching their replacements.

That launch already has been delayed more than a week by bad weather and a minor medical issue involving one of the crew.
