Leading off this week's space news roundup from Overnight News Digest: Science Saturday (Hurricane season arrives) are two videos about the Earth as observed from space by NASA.
First, Science at NASA asks a question about a topic mentioned in Hurricane forecasts as the season begins, ScienceCasts: El Niño - Is 2014 the New 1997?
The Jason-2 satellite sees something brewing in the Pacific. Researchers say it could be a significant El Niño with implications for global weather and climate.Next, more climate research from JPL/NASA in Orbiting Carbon Observatory 2: NASA's New Carbon Sleuth.
NASA's OCO-2 mission, scheduled to launch July 1 from Vandenberg AFB, California, will make precise measurements of carbon dioxide in Earth's atmosphere. The orbiting observatory is NASA's first satellite mission dedicated to studying carbon dioxide, a critical component of Earth's carbon cycle that is the leading human-produced greenhouse gas driving changes in Earth's climate. OCO-2 will provide a better understanding of the sources of carbon dioxide emissions and the natural processes that remove carbon dioxide from the atmosphere, and how they are changing over time.Follow over the jump for the news from and about Mars, along with This Week at NASA and other general space news.
