Dr. Al Grauer hosts. Dr. Albert D. Grauer ( @Nmcanopus ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. travelersinthenight.org

Today's 2 topics:

- Atira, named for the Pawnee goddess of Earth and the Morning and Evening Star orbits the Sun inside of our path. Atira, the first of this type of asteroid, was discovered by the Lincoln Near-Earth Asteroid Research Program using telescopes in New Mexico. Atira is a stony object more than a mile in diameter, spins on it's axis of rotation once every three hours, has an irregular shape, and orbits the Sun once every 233 days. This asteroid was named Atira who is a goddess of the Native American Pawnee tribe. She is the wife of the creator god, Tirawa [Tire a wa]. She is the goddess of Earth and the Morning and Evening star.

- Should martian microbes be sacrificed to human space exploration?

It is unlikely that any living organism could survive being blasted from the surface of a planet, travel through interstellar space on a meteoroid, survive a fiery entry through another planet's atmosphere, and be viable when it reaches the surface. However, humans are breaching this interplanetary barrier. We have robots operating and are planning to land colonists on the red planet. This situation has prompted doctoral student Daniel Helman of Prescott College to ask the question "If Martian microbial life is discovered, is it ethical for humans to colonize Mars even if that means spoiling the environment of the microbes?"

We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.
