2015 marks 50 years of successful NASA missions to Mars starting with Mariner 4 in 1965. Since then, a total of 15 robotic missions led by various NASA centers have laid the groundwork for future human missions to the Red Planet. The journey to Mars continues with additional robotic missions planned...

A Soyruz rocket launched NASA's Scott Kelly and two Russian cosmonauts into space for what will be a year-long mission aboard the International Space Station. It is NASA's first-of-its-kind study of identical twins to learn more about how long-term spaceflight affects the human body — by sending one

The Bigelow Expandable Activity Module (BEAM) will be transported to the International Space Station on a SpaceX Dragon spacecraft.

NASA’s New Horizons spacecraft is speeding towards Pluto for the first-ever flyby on July 14, 2015. Scientists are eager to collect data on the dwarf planet’s chemical and atmospheric makeup, and the Ralph spectrometer will do just that. Instrument scientist Dennis Reuter discusses Ralph, Pluto, and

Scientists say there's a place in our solar system outside of Earth that has the chemical make-up to potentially support life. Researchers found that Saturn's sixth largest moon -- Enceladus -- has an ocean that contains phosphorus, which is found in human teeth, bones and DNA. CBS News space consu...

Welcome to Space! This presentation includes 14 space tourism travel posters which were created by artists working with scientists at NASA's Jet Propulsion Laboratory as part of its "Visions of the Future" series.

Seven Earth-sized planets have been observed by NASA's Spitzer Space Telescope around a tiny, nearby, ultra-cool dwarf star called TRAPPIST-1. Three of these planets are firmly in the habitable zone. Over 21 days, NASA's Spitzer Space Telescope measured the drop in light as each planet passed in fro
