How Do You Make an Earth-like Planet?

Astronomers have spotted many Earth-like worlds around other stars, but are these exoplanets really similar to our home, and could they support life? The CLEVER Planets project, including UC Davis professor Sarah Stewart, has received a $7.7 million NASA grant to explore how rocky planets like Earth acquire, sustain, and nurture the chemical conditions necessary for life.

Curiosity Finds Organic (Carbon-based) Material in Gale Crater, Mars

The Mars Curiosity rover team announced today (June 7) finding organic matter – carbon-based compounds – in three billion year old mudstone sediments from Gale Crater. They also found seasonal changes in the amount of methane in the local atmosphere.

Looking For Martians At McLaughlin Reserve

By Kathleen Wong

In a universe with billions upon billions of planets, narrowing the search for extraterrestrial life is no mean feat. One approach seeks analogs of otherworldly conditions here on Earth, and characterizes the mineralogy, geochemistry and biology of these areas.

Students’ rocket to fly in NASA competition

A team of UC Davis students aims to fly their rocket exactly one mile high April 20 during NASA’s Student Launch Projects competition near Huntsville, Alabama. This is the first NASA Student Launch Projects 2013year the UC Davis SpaceED rocket team has taken part in the national competition.

The aim of the competition is to design, build and launch a rocket that can fly to an altitude of exactly one mile carrying a scientific payload, said team member Dan Berman, a fourth-year undergraduate majoring in mechanical engineering and aerospace engineering. Teams lose points for every foot of altitude above or below the one-mile mark.
