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

All landings on Mars are difficult, but NASA's Perseverance rover is attempting to touch down in the most challenging terrain on Mars ever targeted.

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...

Our SpaceX Crew-6 mission safely returns to Earth, the tech demo hitching a ride on our Psyche spacecraft, and studying ancient life on Earth to better understand Mars … a few of the stories to tell you about – This Week at NASA!

What does it take to get a spacecraft to Mars? This 60-second video covers a few key things to remember when planning a trip to the Red Planet.

NASA's New Horizons spacecraft has begun beaming back photographs of the surface of Pluto as it approaches the dwarf planet. . Report by Conor Mcnally.

NASA's Mars Exploration Rover Mission (MER) is an ongoing robotic space mission involving two rovers, Spirit and Opportunity, exploring the planet Mars. It began in 2003 with the sending of the two rovers—MER-A Spirit and MER-B Opportunity—to explore the Martian surface and geology.

The spacecraft crashed into an asteroid the size of the Washington Monument. NASA’s DART spacecraft intentionally collided with an asteroid on Monday evening, in an attempt to alter the space rock’s trajectory. The mission tested technology that could help defend Earth against potential future aster

NASA’s Perseverance Rover has reached the Red Planet and will go through the final phase known as Entry, Descent and Landing. Perseverance was launched on July 30, 2020, from Cape Canaveral Space Force Station, aboard an ULA’s Atlas V-541 rocket, and will land on Mars at Jezero Crater after travelli

Mars is a cold and barren desert today, but scientists think that in the ancient past it was warm and wet. The loss of the early Martian atmosphere may have led to this dramatic change, and one of the prime suspects is the solar wind. Unlike Earth, Mars lacks a global magnetic field to deflect the s
