Two NASA astronauts successfully installed a new docking adapter Wednesday for incoming SpaceX and Boeing vehicles that may arrive with crew as early as this year.

One of the sources of mysterious energy blasts could be relatively nearby, scientists say

"To look forward to the Moon, we need to learn from the past."

For a long time the fate of NASAs Europa Clipper mission has been uncertain. But yesterday NASA announced that the mission can now enter its next phase, where the design will be finalized and the spacecraft built and tested. “We are all excited about the decision that moves the Europa Clipper mission one key step closer to unlocking the mysteries of this ocean world,” said Thomas Zurbuchen, associate administrator for the Science Mission Directorate at NASA Headquarters in Washington.

The endeavor to put the first woman—and the next man— on the moon will likely cost between $20 and $30 billion over five years.

Astronomers have discovered evidence for the farthest “cloaked” black hole found to date, using NASA’s Chandra X-ray Observatory. At only about 6% of the current age of the universe, this is the first indication of a black hole hidden by gas at such an early time in the history of the cosmos.

Recently, near the sleepy south Texas beachside town of Boca Chica, a stubby vehicle that looks like a water tank with legs, shining with its stainless-steel hull, rose 20 meters, wreathed in fire and smoke, before it descended back to the ground. The brief flight test of the Starhopper took a few seconds, though it started a grass fire that took a long time to put out. If Elon Musk, the CEO of SpaceX, is right, the short hop is just the beginning of a journey that will take humankind back to the moon, on to Mars — and then beyond.

TESS, a space telescope searching for alien worlds, helped astronomers discover a potentially watery new planet. It's one of the nearest known worlds.

Accompanying the map is a video that takes you through the number of exoplanets discovered since the year 1991.

Made In Space will show how well robotics can 3D-print parts for in-space construction.

Opinion: For decades, NASA's been under-funded. Apollo 11 getting to the moon was a miracle of science and engineering. Can we do it again?

While the world celebrated the 50th anniversary of the Apollo 11 moon landing Saturday, Sotheby's auctioned off three original NASA videotapes of the event for a whopping $1.82 million.

On Tuesday afternoon, NASA announced 19 new partnerships with 10 US companies to help bring more cutting-edge technologies closer to production use in spaceflight. There were a lot of useful engineering ideas here, such as precision landing systems and robotic plant farms, but perhaps the most intriguing one involved the rocket company SpaceX and two of NASA's field centers—the Glenn Research Center in Ohio and the Marshall Space Flight Center in Alabama.

Scientists at NASA are tracking six asteroids that will be heading in the direction of our planet during the next few weeks, and one of them is larger than the Empire State Building. But, first things first. Take a deep breath. Experts are assuring us there’s no reason to panic.

On June 13 NASA’s official tally of exoplanets—planets beyond our solar system—shot past 4,000. The master list includes alien worlds around around both tiny neutron stars and swollen, dying suns, planets in the crowded center of our galaxy the Milky Way, and planets floating alone in the depths of interstellar space. One location is conspicuously missing, however: Alpha Centauri, the star system next door to our own.

The agency plans to launch a spacecraft to Titan, a moon of Saturn with some crucial ingredients for habitability.

Gone is the haze of cigarette, cigar and pipe smoke. Gone are the coffee, soda and pizza stains. With only a few exceptions, NASA's Apollo-era Mission Control has been restored.

Many aspects of how the human body will react to long periods in space remain unknown. But researchers are beginning to get some answers.

Fifty years on, here are four things that made the Apollo Moon programme one of humankind's greatest technological achievements.
