NASA has released a dataset displaying how temperatures and precipitations might change by the year 2100 taking into account various greenhouse gas emission scenarios. This 25-km high resolution data is of free access to the public and shows estimated maximum and minimum temperatures as well as precipitations on a daily basis and at a local and global scale from 1950 to 2100 under two different greenhouse gas emission scenarios: a “business as usual” scenario based on current trends and an “extreme case” with huge carbon dioxide increases.

NASA's new Soil Moisture Active Passive (SMAP) mission has begun science operations. SMAP investigates global soil moisture and detect whether soils are frozen or thawed. This information help scientist understand links among Earth’s water, energy and carbon cycles. In addition, map global soil moisture can help to monitor and predict natural hazards like floods and droughts.

NASA satellites show: Earth is a cloudy place

Decades of satellite images show: Earth is a cloudy place (Image: NASA)

Satellite-based Earth observation as well as images taken by astronauts show that Earth views from space are dominated by clouds. A recent study by NASA has looked at a decade of imagery and estimates that about 67 percent of Earth’s surface is typically covered by clouds.

NASA and NSF celebrate 20th Anniversary of the GLOBE Programme

The GLOBE Programme helps pupils and students make connections between their local environment and the entire Earth system (Imagine: NASA)

Tomorrow, on Earth Day, April 22, NASA and the National Science Foundation (NSF) celebrate 20 years of the Global Learning and Observations to Benefit the Environment (GLOBE) programme. This science and education programme make it possible that students, teachers and scientist work together and participate in science data collection through hands-on science in their local communities.

Since its inception on Earth Day 1995, 114 countries, 28,000 schools and over 10 million students have participated in the GLOBE Programme.

13 April 2015 was the 55th anniversary of the first navigation system reaching the orbit. The Transit 1B satellite was launched by NASA on 13 April 1960.

This satellite was designed to provide positioning for the US Navy’s fleet of Polaris ballistic missile submarines, a task it performed for over 30 years, as Money Week informs.
