Dzhezkazgan, Kazakhstan —
Ultimate Thursday, American astronaut Christina Koch arrived again on Earth after 328 days in house. That’s the longest spaceflight ever made by way of a girl, and simply some of the many stuff Ms. Koch completed in house.
Ms. Koch, who’s 41, took off from Earth for the Global Area Station (ISS) on March 12, 2019. Whilst Ms. Koch was once in house, she made 5,248 journeys across the Earth. She traveled 139 million miles (223.7 million kilometers), which NASA says is kind of the similar as 291 journeys to the Moon and again.
On Thursday, Ms. Koch landed safely in Kazakhstan, at the side of Italian astronaut Luca Parmitano and Russian cosmonaut (astronaut) Alexander Skvortsov.
Her time in house is simply some of the data set by way of Ms. Koch. In October of final yr, Ms. Koch led the primary ever all-female spacewalk with NASA astronaut Jessica Meir.
All through her 11 months at the ISS, Ms. Koch took section in six spacewalks, together with 3 all-female spacewalks. In all, she spent over 42 hours outdoor the station.
However for many astronauts, house go back and forth isn’t about surroundings data. It’s about doing science. Ms. Koch took section in all kinds of particular experiments whilst she was once at the ISS. Her paintings integrated finding out how crystals develop in house, how fireplace behaves in house, and the way atoms behave in excessive chilly.
She did many experiments aimed toward studying extra about rising crops in low gravity. Rising crops in house may well be crucial method to supply meals on long term journeys.
Ms. Koch additionally labored on an experiment which examined a brand new method of setting apart liquids from gases. This experiment may just result in easy strategies of cleansing water and air in house, which may well be crucial for long term house go back and forth.
Ms. Koch isn’t only a scientist and an astronaut. She may be being studied. She’s a part of a NASA program finding out how astronauts are suffering from being in house for lengthy sessions of time. Ms. Koch’s 328-day shuttle was once best 12 days shorter than the American report set by way of NASA astronaut Scott Kelly in 2016.
As they did with Mr. Kelly, NASA scientists can be having a look moderately at techniques Ms. Koch’s frame has been suffering from her time in house. That analysis is vital for the longer house journeys NASA hopes to make one day, reminiscent of for a base at the moon or a shuttle to Mars.
Ms. Koch says she is going to leave out the superb perspectives of Earth, and with the ability to drift round in very low gravity. She will even leave out her buddies from the ISS. However she mentioned she was once having a look ahead to many straightforward Earth reports which can be unimaginable in house, reminiscent of “the sensation of wind on my face.”
