How the exam will ask it
પ્રિલિમ્સ
- Martian meteorites are rocks ejected from Mars by asteroid or comet impacts that later landed on Earth.
- Teghaza 001, found in the Sahara Desert, is among the oldest Martian meteorites identified so far.
- Meteorites provide direct physical samples of a planetary crust for laboratory study on Earth.
મેઇન્સ
GS3 Science & Technology (space): planetary science and the study of extraterrestrial material. Meteorites offer low-cost direct samples of Mars's crust, complementing rover and orbiter missions and sample-return plans. For India, this strengthens the case for investing in planetary science, lab capacity for isotopic dating and participation in international space research.
