Our Mission

Our mission is to build a future in which people live in harmony with nature. From our experience as the world's leading independent conservation body, we know that the well-being of people, wildlife and the environment are closely linked. That's why we take an integrated approach to our work.
We're striving to safeguard the natural world, helping people live more sustainably and take action against climate change. We spend a lot of time working with communities, with politicans and with businesses to find solutions so people and nature can thrive.
Our projects are innovative, collaborative and based on scientific evidence. And we think big. We run a number of Global initiatives focussing on the regions and challenges where we can make the biggest difference - from the Arctic and the Amazon to responsible fishing.

Thirty people are behind bars in Russia following a peaceful protest against oil drilling in the Arctic. They took action because they know it is wrong to exploit melting ice to drill for more of the oil that is warming our world. The Arctic 30, including a freelance photographer and a freelance videographer, have been refused bail and charged with piracy. It is an absurd accusation that carries a maximum 15 year jail sentence. Help us free them.

Where are you from?

I was born in Indianapolis, Ind., and attended Perry Meridian High School. My teachers there gave me an opportunity to push beyond the standard curricula in science, math, economics, and government.


Describe the first time you made a personal connection with outer space.

As a child, I was spell-bound by the Apollo astronauts as they began to explore the Moon. Their work inspired me so much. I look forward to a time when humans once again explore the Moon and beyond, because we need those types of events to inspire a new generation of students.

Mars Crater May Actually Be Ancient Supervolcano


Scientists from NASA and the Planetary Science Institute in Tucson, Ariz., have identified what could be a supervolcano on Mars—the first discovery of its kind.

The volcano in question, a vast circular basin on the face of the Red Planet, previously had been classified as an impact crater. Researchers now suggest the basin is actually what remains of an ancient supervolcano eruption.

Mammals

Included in the IUCN Red List is the comprehensive assessment of the conservation status of the world's 5,488 mammal species. Here you will find global summary statistics for the assessment, as well as individual species accounts including IUCN Red List threat category, range map, ecology information, and other data for every mammal species.
The current dataset on mammals is the product of one of several global initiatives led by IUCN and partners to rapidly expand the geographic and taxonomic coverage of the IUCN Red List.
Use the search tool at the top of the page to search for mammals in the IUCN Red List database by name, taxonomy, country, region, habitat type, threat type, or IUCN Red List status.

Quizás usted haya notado que la apariencia de las historias de Ciencia@NASA ha cambiado. No hay motivo para alarmarse. Nuestro producto principal, las historias sobre ciencia de la NASA, contadas de manera simple y clara, continúa siendo el mismo. Los cambios son una señal de progreso. Recientemente, el equipo de Ciencia@NASA unió sus fuerzas al Directorio de Misiones Científicas, en las oficinas centrales de la NASA. Trabajando juntos, podremos cubrir una gama más amplia de descubrimientos de la NASA y podremos desarrollar para nuestros lectores oportunidades relacionadas con la "ciencia ciudadana". Asimismo, continuaremos incluyendo los antiguos favoritos, como las Crónicas del Apollo, y buscaremos historias sobre eventos de astronomía informados por aficionados. El cielo es el límite.
