Is there any challenging doctor job like ISRO scientists working for mars mission

Is there any challenging doctor job like ISRO scientists working for mars mission(inspired after watching mission mangal)or is there any scope for doctors(orthopedicsšŸ˜) in ISRO/NASA??
Yesā€¦ about ISRO, check their websiteā€¦ but they accept only if there is vacancy (which is rare) and they accept only the most experienced onesā€¦

there are companies like skyroot, agnikul and Bellatrix aerospace, which are at primary stages of any mission from earth, i wish to join that too, but as of now i canā€™t see any opening of doctors there

Bhaiā€¦ le tumne ortho rakhi haiā€¦ aur tume challenging kaam chahiye ā€¦ bc 5 ginti ki dawaiya yaad karni hoti haiā€¦ ortho wale doctor kam mechanic jada hote hai ā€¦ drill , screws, steel plates ā€¦

MD Covid. The challenging job is to not get infected while wearing govt given surgical masks as ppe when you examine covid patientsā€¦
