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.

Another giant leap towards a mission to Mars: expendable structures could be the next extraterrestrial breakthrough, as they weight less to launch and are more compact on the rocket. On arrival, they can be inflated to provide safe and sustainable living quarters, work spaces and laboratories for pe...

The goal of 3-D printing is to take this capability to microgravity for use on the International Space Station. In space, whatever astronauts have available on orbit is what they have to use -- but just like on Earth, parts break or get lost. When that happens, there's a wait for replacement parts, ...

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...

Soyuz,a Russian spacecraft carrying a three-man crew blasted off Friday from a launch pad in the steppes of Kazakhstan, for the first time taking a shorter path to the International Space Station. Instead of the two-day approach maneuver used by Soyuz spacecraft in the past, this journey to the stat...

Have you ever wondered why some telescopes are launched into space while others are built on remote mountain tops? What is actually the best for astronomy? Here we provide a ringside view of the fight for the elusive photons from deep space - is it a battle of the telescope giants?

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

This video zooms into the core of a rich star-birth region called the Lagoon Nebula, located in the constellation Sagittarius in the direction of our Milky Way galaxy’s central bulge.

Jupiter has a lot going on, with massive storms, intense winds, auroras, and severe temperature and pressure extremes. The James Webb Space Telescope of NASA has now taken fresh images of the planet. Webb's Jupiter observations will provide scientists with much more information about Jupiter's inner...
