Technicians carefully install a piece of equipment to house Gateway’s xenon fuel tanks, part of its advanced electric propulsion system. Gateway’s Power and Propulsion Element, which will make the lunar space station the most powerful solar electric spacecraft ever flown, recently received the xenon and liquid fuel tanks for its journey to and around the Moon.
Technicians in Palo Alto, California carefully install a piece of equipment that will house the tanks. Once fully assembled and launched to lunar orbit, the Power and Propulsion Element’s roll-out solar arrays – together about the size of an American football field endzone – will harness the Sun’s energy to energize xenon gas and produce the thrust to get Gateway to the Moon’s orbit where it will await the arrival of its first crew on the Artemis IV mission.
The Power and Propulsion Element will also carry the European Radiation Sensors Array science experiment provided by ESA (European Space Agency) and JAXA (Japan Aerospace Exploration Agency), one of three Gateway science experiments that will study solar and cosmic radiation. The little understood phenomenon is a chief concern for humans and hardware journeying to deep-space destinations like Mars and beyond.
The Power and Propulsion Element is managed out of NASA’s Glenn Research Center in Cleveland, Ohio and built by Maxar Space Systems of Palo Alto, California.

Over the years, numerous mysterious events have been witnessed in the sky, defying explanation. Recently, yet another unusual sky phenomenon was observed over Southern Australia capturing attention and sparking curiosity.
Video footage reveals what appears to be a dome-shaped structure, with an even stranger detail: lightning seems to bounce off or perhaps even originate from within the dome.
The mysterious formation has led to numerous theories. Some viewers suggest it could be a unique (red) rainbow or a rare weather event like a haboob (sandstorm). Others speculate it might be the result of weather manipulation or even an energy field projected over the region.
Opinions also vary on the lightning, some say it’s bouncing off the dome, while others believe it could be emanating from within. Although it may just be an unusual natural phenomenon, the seemly strange interaction with the lightning remains unexplained.

NASA’s SpaceX Crew-8 members, from left to right, Roscosmos cosmonaut Alexander Grebenkin and NASA astronauts Michael Barratt, Matthew Dominick, and Jeanette Epps, are seen inside the Dragon spacecraft shortly after having landed off the coast of Pensacola, Florida, on Oct. 25, 2024. Credit: NASA/Joel Kowsky NASA’s SpaceX Crew-8 mission successfully splashed down at 3:29 a.m. EDT Friday, off Pensacola, Florida, concluding a nearly eight-month science mission and the agency’s eighth commercial crew rotation mission to the International Space Station.
After launching March 3 on a SpaceX Falcon 9 rocket from NASA’s Kennedy Space Center in Florida, NASA astronauts Matthew Dominick, Michael Barratt, and Jeanette Epps, as well as Roscosmos cosmonaut Alexander Grebenkin, spent 232 days aboard the space station.
Recovery teams from NASA and SpaceX quickly secured the spacecraft and assisted the astronauts during exit. The crew now will head to NASA’s Johnson Space Center in Houston, while the Dragon spacecraft will return to SpaceX facilities at Cape Canaveral Space Force Station in Florida for inspection and refurbishment for future missions.
During their mission, crew members traveled nearly 100 million miles and completed 3,760 orbits around Earth. They conducted new scientific research to advance human exploration beyond low Earth orbit and benefit human life on Earth. Research and technology demonstrations included conducting stem cell research to develop organoid models for studying degenerative diseases, exploring how fuel temperature affects material flammability, and studying how spaceflight affects immune function in astronauts. Their work aims to improve astronaut health during long-duration spaceflights, contributing to critical advancements in space medicine and benefitting humanity.
Crew-8’s return follows the arrival of NASA’s SpaceX Crew-9 to the orbiting laboratory Sept. 29. These missions are part of NASA’s Commercial Crew Program, which provides reliable access to space, maximizing the use of the station for research and development and supporting future missions beyond low Earth orbit by partnering with private companies to transport astronauts to and from the space station.

Last Monday, paraglider Alex Lang was flying high above the Great Pyramid of Giza when he noticed unexpected movement at its peak. To his surprise, it wasn't a person, but a dog perched at the top of the ancient monument.
Image credit: Alex Lang.
Lang, who recorded the bizarre sighting, described the dog barking and chasing birds from the very summit of the pyramid.
The footage left people both fascinated and confused, wondering how the dog had managed to scale such an immense structure. Some even joked that it might be a manifestation of Anubis, god of funerary practices and care of the dead. However, the main concern was whether the dog could safely make its way back down.
Luckily, a few days later, the dog was captured on video making its way down the ancient landmark, appearing calm and unscathed, as if the climb had been no big deal.
