Physics Spl

The Indian Institute of Astrophysics is a premier institute devoted to research in astronomy, astrophysics and related physics. You can do B.Sc (Hons.) and join IIA for higher studies to become astronomer.
An astronaut is a person trained by a human space flight program to command, pilot or serve as a crew member of a spacecraft. Although, generally reserved for professional space travelers, the terms are sometimes applied to anyone who travels into space including scientists also. Following are the general eligibility criteria to become astronaut:
(a) Bachelor's degree from a recognised university in engineering, science, or mathematics, etc. An advanced degree is desirable.
(b) At least 1,000 hours pilot-in-command time in jet aircraft. Flight test experience is highly desirable.
(c) Medically fit
India's first two astronauts were from Indian Air Force Fighter Pilot branch.
In India it may be difficult to pursue both careers of astronaut and astronomer simultaneously.

Geology is one of the core stem subjects and a Bachelor's degree will be required at the very minimum for most jobs. In some states and for some jobs (especially where safety issues are concerned - such as in mines) certification may be required to practice. This should not be the case in the overwhelming majority of cases.
Most major colleges and universities offer geology degrees, so you should not struggle to find a relevant course. Even, these are not available at your chosen college, geography or other earth sciences are the preferred options. Students should take minors in mathematics and physics or other earth science options, and IT related subjects. GIS is one example of a growing and required IT skill in geology.
Although, there is a skills shortage, students are advised to study Master's degrees due to the applied science and project work that this would entail. Employers prefer graduates with work experience in their chosen field. Summer schools during Bachelor's degrees are useful too. Doctorates are useful for those, who want to pursue a career in academia, teaching, research or both. They are also advantageous for senior positions such as government advisory roles.
