Russian cosmonauts Oleg Artemyev and Denis Matveev will suit up and head outside the International Space Station Wednesday for a spacewalk to continue outfitting the European Space Agency’s robotic arm delivered to the complex last year.

This Fall, the fifth crewed mission (Crew-5) of the NASA Commercial Crew Program will depart for the International Space Station (ISS). This mission will see four astronauts launch from the Kennedy Space Center in Flordia aboard a SpaceX Crew Dragon (atop a Falcon 9 rocket). Once they reach the ISS, they will join the crew of Expedition 67 and conduct science experiments as part of Expedition 68. The mission commander of this flight, Nicole Aunapu Mann, is a naval aviator and test pilot with a distinguished military career. She will also be the first Indigenous woman ever to go to space!
The world's largest airline has agreed to buy 20 Boom Supersonic Overture jets, expected to carry passengers at twice the speeds of conventional passenger aircraft.
Scientists will study the effects of radiation on yeast in preparation for long-duration crewed missions to deep space.
Ancient grains of dust that are older than the solar system itself have been found in samples from asteroid Ryugu brought to Earth by the Japanese Hayabusa2 spacecraft nearly two years ago.
A powerful and spectacular cosmic dance that began a billion years ago will lead to a collision and merger between two galaxies and the supermassive black holes at their hearts.
Scientists studied the trajectory and debris field of asteroid 2008 TC3 to determine which specific parts of the space rock made it down to the Earth's surface.
A Chinese X-ray telescope has detected the strongest-ever magnetic field recorded by making observations of a rapidly-spinning neutron star, or magnetar.
The sun has spat out two clouds of plasma in the past two days, which might trigger beautiful aurora displays observable as far south as New York later this week.
Artemis 1 is the first stage of the Artemis program designed to return astronauts to the moon. The uncrewed mission will travel to the moon and back.

An international team of researchers has devised a plasma-based approach to producing oxygen on Mars to support exploration.
We have discovered thousands of exoplanets in recent years. Most have them have been discovered by the transit method, where an optical telescope measures the brightness of a star over time. If the star dips very slightly in brightness, it could indicate that a planet has passed in front of it, blocking some of the light. The transit method is a powerful tool, but it has limitations. Not the least of which is that the planet must pass between us and its star for us to detect it. The transit method also relies on optical telescopes. But a new method could allow astronomers to detect exoplanets using radio telescopes.
The Orion Nebula is a giant cloud of gas and dust that spans more than 20,000 times the size of our own solar system. It one of the closest active star-forming regions to Earth, and is therefore one of the most observed and photographed objects in the night sky. The venerable Hubble Space Telescope has focused on the Orion Nebula many times, peering into giant cavities in the hazy gas, and at one point, Hubble took 520 images to create a giant mosaic of this spellbinding nebula.
Students at the Delft University of Technology (TU Delft) in the Netherlands are developing the world's smallest and lightest moon rover, called Lunar Zebro.
Scientists think that when dark photons collect around black holes, they can get trapped and boosted to high energies, where they might transform into other particles (or even just normal photons).
Earth is the only planet we know possesses continents, a scientific mystery, but new research indicates the continents may have been created by meteorite impacts in Earth's distant history.
A new NASA video "Path to the Pad: The Rocket" details the awesome might of the SLS megarocket.
There’s an ocean of human-made garbage floating through Earth’s seas. From plastic straws to beverage bottles and food wrappers, the ocean waters are this planet’s fastest-growing junkyard. Some of the plastic gets ground into little beads, and ends up in the food chain, with humans at the top. For that reason, and many others, the European Space Agency is tracking ocean-bound plastics through the auspices of the MARLISAT project. It’s one of 25 efforts created to identify and trace marine litter as it moves through the world’s waterways. The ultimate goal is to help countries reduce ocean litter, particularly plastics.
