A new crew has rocketed toward the International Space Station to replace the astronauts who returned to Earth early in NASA’s first medical evacuation. SpaceX launched the replacements as soon as possible at NASA’s request, sending the US, French and Russian astronauts on an expected eight- to nine-month mission stretching until Autumn.NASA had to put spacewalks on hold and deferred other duties while awaiting the arrival of Americans Ms Meir and Jack Hathaway, France’s Sophie Adenot and Russia’s Andrei Fedyaev. With missions becoming longer, NASA is constantly looking at upgrades to the space station’s medical gear. Do you think that space missions are worth the human endevours ?
