Appendix cancer occurs when healthy cells in the appendix change and grow out of control. These cells form a growth of tissue, called a tumor. A tumor can be cancerous or benign. A cancerous tumor is malignant, meaning it can grow and spread to other parts of the body. Another name for this type of cancer is appendiceal cancer.
Russian astronaut breaks record for longest time spent in space. By Nicola Harley. 12:52PM BST 12 Sep 2015. Comments. An astronaut has broken the record for the longest amount of time spent in space becoming the world's most experienced space flier. Russian cosmonaut Gennady Padalka, 57, has spent a record 879 days in space throughout his career as he return from his latest mission from the International Space Station.
The longest duration achieved on multiple missions, more than two years, was logged by cosmonaut Sergei Krikalev over the course of his six missions. U.S. astronaut Peggy Whitson holds the cumulative female record for most time spent in space on multiple flights with 376 days and she is now training to launch on her third flight in March 2016. Cristoforetti has set more than duration records during her Expedition 42/43 stay on the station, a mission that ESA named Futura.
