H. Jay Melosh (June 23, 1947 – September 11, 2020) was an American scientist. He was a geophysicist, which means he studied the Earth and other planets. Dr. Melosh was especially famous for his work on impact cratering. This is the study of how craters are formed when objects like asteroids hit planets.

A Scientist Who Studied Space Rocks
Jay Melosh earned his first degree in physics from Princeton University. Later, he got his PhD in physics and geology from Caltech in 1972. His early research was even about tiny particles called quarks!
What Did He Study?
Dr. Melosh was very interested in how planets change. He studied impact craters, which are big holes left by space rocks. He also looked at planetary tectonics, which is how the surfaces of planets move and change.
He also researched earthquakes and landslides on Earth. His work helped us understand how these powerful events happen.
Amazing Discoveries
Dr. Melosh studied the giant impact origin of the Moon. This idea suggests our Moon formed from a huge collision. He also researched the Chicxulub crater. This giant crater was made by an asteroid impact that many scientists believe wiped out most dinosaurs.
He also studied how rocks get blasted off planets. This happens when a large object hits a planet. These rocks can then travel through space.
Life Beyond Earth
Dr. Melosh was also involved in astrobiology. This field explores the possibility of life on other planets. He studied how tiny living things, called microorganisms, might travel between planets. This idea is sometimes called panspermia. It suggests life could spread through space on rocks.
Awards and Recognition
Dr. Melosh was a member of several important science groups. These included the American Geophysical Union and the Geological Society of America. He also belonged to the Meteoritical Society, which studies meteorites.
He received the Barringer Medal for his work on the physics of impacts. He also won the G. K. Gilbert Award from the Geological Society of America. In 2003, he was elected to the National Academy of Sciences, a very high honor for scientists.
- Asteroid 8216 Melosh is named in his honor.
- He received the American Geophysical Union's 2008 Harry H. Hess Medal. This award was for his amazing research on how Earth and other planets formed and changed.
