NASA's mission DART will test our ability to redirect an asteroid by quite literally crashing into it — but the spacecraft will also test a new type of propulsion system for the agency.

Want to be one of the first to take a ride on Virgin Galactic's spaceship? That'll cost you a cool $450,000.

A NASA spacecraft is giving the best-ever 3D model of the largest planet of our solar system. The Juno mission is using its second extended phase to peer far into the clouds of Jupiter, using a polar-orbiting view that no previous spacecraft was able to access.

Scientists may have detected signs of a planet transiting a star outside of the Milky Way, in what could be the first planet ever to be discovered outside our galaxy.

Attention asteroid aficionados: NASA is set to launch a series of spacecraft to visit and even bash some of the solar system's most enticing space rocks. The robotic trailblazer named Lucy is up first, blasting off this weekend on a 12-year cruise to swarms of asteroids out near Jupiter—unexplored time capsules from the dawn of the solar system. And yes, there will be diamonds in the sky with Lucy, on one of its science instruments, as well as lyrics from other Beatles' songs.

When the Soviet Union launched Sputnik 1 in 1957, it represented humanity's first significant foray into the cosmos. Our imagination was opened to the wonder and lure of space for human endeavor as science fiction suddenly became science fact.

The gargantuan Bernardinelli-Bernstein comet will strafe Saturn's orbit in 2031. Scientists are stoked.

NASA has announced that it will launch Psyche in August 2022 to reach the asteroid belt between Mars and Jupiter. But there is something unique about this spacecraft—it will travel across space using a "solar electric propulsion" system.

Elon Musk said on Twitter that SpaceX plans to upgrade the amenities for its next space-tourist flight, including the toilet. The Inspiration4 crew, made up of four civilian astronauts, took off on Wednesday aboard SpaceX's Crew Dragon spacecraft. They landed back on Earth on Saturday evening.

Caltech astronomer and Pluto killer Mike Brown claims he has found evidence of a potential planet in the Kuiper Belt roughly 100 billion miles from Earth.

To get us to Mars and beyond, a team of students from around the world has a plan involving lunar rovers mining ice and a space station between the Earth and the moon.

If the idea of sending humans to Mars is a romantic one, the reality of it is a bucket of cold water. Going to Mars is hard. Something like half of all missions have failed for one reason or another, but adding humans into the mix makes things far harder.

Elon Musk’s SpaceX is aiming to cement its position as a leading space enterprise with a mission this week that seeks to deliver four civilians to orbit for several days and then return them to Earth.

The Defense Innovation Unit last week issued a call for bids for small nuclear-powered engines for space missions beyond Earth orbit. DoD wants “lightweight, portable and long-duration power sources that can support propulsion and on-station power for sensing and communication on small- and medium-sized spacecraft,” says the solicitation.

SpaceX's first all-civilian launch is scheduled to launch on Tuesday (Sept. 14) carrying a message of diversity during the third billionaire-led flight to launch in 2021. The mission, called Inspiration4, includes four private citizens who will fly on a Crew Dragon spacecraft for an Earth-orbiting mission.

The number of known planets in our solar system has changed over time, but we’re currently sitting at eight since the demotion of Pluto to dwarf planet. However, some scientists believe there is a ninth planet lurking out there in the inky blackness at the edge of the solar system. A new analysis supports the notion that there’s something out there, and it also narrows the region we need to search if we want to find the contentious Planet Nine.

China is looking at the ways of getting astronauts to Mars and back safely and potentially establishing a long-term presence on the Red Planet.

Just because you were in space doesn't mean you get the wings of an astronaut. The Federal Aviation Administration set new rules concerning the Commercial Space Astronaut Wings Program and the criteria used to award those commanding, piloting or working on privately funded spacecraft with the Commercial Space Astronaut Wings badge.

Following the conclusion of World War II in the 1940s, worldwide superpowers started developing rocket propulsion technologies in aircraft, ultimately leading to supersonic planes like the North American X-15 and the first Race for Space. Currently, a new rivalry is brewing among private businesses seeking to expand outside our borders.

The commercial race to get tourists to space is heating up between Virgin Group founder Sir Richard Branson and former Amazon CEO Jeff Bezos. On July 11, Branson ascended 80 km (49 miles) to reach the edge of space in his piloted Virgin Galactic VSS Unity spaceplane, while Bezos’ autonomous Blue Origin rocket launched today on July 20, coinciding with the anniversary of the Apollo 11 Moon landing. Although Bezos launched later than Branson, he set out to reach higher altitudes — about 120 km, or 74 miles.
