China’s Shenzhou 19 astronauts take the reins of Tiangong space station (video)

NeRD

China’s Shenzhou 18 crew have passed the keys to the Tiangong space station to its new occupants. The Shenzhou 19 mission launched on a Long March 2F rocket from Jiuquan spaceport in northwest China on Oct. 29 and arrived at the Tiangong space station 6.5 hours later.  Shortly thereafter, at 12:51 a.m. EDT (0451 GMT) on Oct. 30, the hatch between the Shenzhou 19 spacecraft and Tiangong was opened, allowing the three Shenzhou 18 mission astronauts to greet the trio of new arrivals aboard. The formal handover of the station…

Small moon of Uranus may have once had a subsurface liquid water ocean

NeRD

Over the last few decades, planetary scientists have been steadily adding to the list of moons in our solar system that may harbor interior oceans either currently or at some point in their past. For the most part, these moons (such as Europa or Enceladus) have been gravitationally bound to the gas giants Jupiter or Saturn.  Recently, though, planetary scientists have been turning their attention further afield, towards the ice giant Uranus, the coldest planet in the solar system. And now, new research based on images taken by the Voyager…

This article was originally published at The Conversation. The publication contributed the article to Space.com’s Expert Voices: Op-Ed & Insights. Loizos Heracleous is a Professor of Strategy at the Warwick Business School, University of Warwick. SpaceX has launched its Crew Dragon spacecraft on a “rescue mission” to bring back two astronauts stranded at the International Space Station (ISS) since June. Butch Wilmore and Suni Williams travelled to the space station on Boeing’s Starliner spacecraft, which was on its first mission with a human crew. But several engines malfunctioned once in…

Earth sure looks spooky in these ‘hyperspectral’ images from Europe’s Hera asteroid probe

NeRD

A strange Earth shines in new imagery captured by a European asteroid mission. The Hera spacecraft, which launched this month to study a binary asteroid system up close. turned its gaze back at our planet to capture spooky views of Earth in multiple wavelengths of light. The imagery was captured fro roughly 1.25 million miles (2 million kilometers) away, using Hera’s HyperScout H hyperspectral imager. Besides being beautiful space art, the imagery “allows us to observe cloud patterns on our planet”, instrument team member Marcel Popescu of Romania’s University of…

Can ‘failed stars’ have planets? James Webb Space Telescopes offers clues

NeRD

Using the James Webb Space Telescope, astronomers have discovered that planet-forming disks in the Orion nebula actually surround “failed stars,” or brown dwarfs. This is the first confirmation that planet-forming, flattened clouds of gas and dust called “protoplanetary disks” surround these peculiar cosmic objects. The team discovered this while using the James Webb Space Telescope (JWST) to follow up on observations of protoplanetary disks, or “proplyds,” illuminated by ultraviolet light in the Orion Nebula. Those observations were collected by the Hubble Space Telescope. These findings could help scientists understand how…

NASA astronaut snaps spooky photo of SpaceX Dragon capsule from ISS

NeRD

A SpaceX Dragon capsule looks a little ghostly in a new image taken from the space station. NASA astronaut Don Pettit snapped a picture of the Crew Dragon Freedom after the Crew-9 mission, SpaceX‘s ninth operational astronaut effort for the agency, docked at the International Space Station (ISS) on Sept. 29. The black-and-white image shows the belly of the Dragon, including windows with filters on board to lessen the bright sun. “I like how the sun shines through the stitching, personifying the composition,” Pettit wrote Oct. 24 on X, formerly…

Apollo 11 moonwalker Buzz Aldrin endorses Trump for president

NeRD

One of the United States’ most famous space explorers is backing Donald Trump for president. Apollo 11 astronaut Buzz Aldrin, the second person ever to walk on the moon, endorsed Trump in a statement today (Oct. 30), less than a week before the Nov. 5 presidential election. “Over the years, I have seen our government’s approach to space wax and wane, a fluctuating dynamic that has disappointed me from time to time,” the former moonwalker wrote in the statement, which was released by Buzz Aldrin Ventures LLC. “But under the…

1st image of our Milky Way’s black hole may be inaccurate, scientists say

NeRD

What does the supermassive black hole lurking at the center of our galaxy look like?It’s a deceptively simple question.  Although our local cosmic abyss, named Sgr A* (short for Sagittarius A*), resides just 26,000 light-years from Earth, it has proven to be a very difficult object to image. This is thanks in part to material whipping around it at near light-speeds. However, after years of trying, scientists with the Event Horizon Telescope (EHT) project succeeded in 2022.The black hole’s silhouette emerged from the shadows, appearing like a fuzzy orange doughnut.…

NASA’s Perseverance rover gets stunning view of big Mars crater from slippery slope (video, photos)

NeRD

NASA’s Perseverance rover took a break from its Mars mountaineering expedition recently to survey its old stomping grounds. The car-sized Perseverance landed on the floor of the 28-mile-wide (45-kilometer-wide) Jezero Crater in February 2021 to hunt for signs of past Mars life and collect dozens of samples for future return to Earth. Perseverance has finished its work in Jezero’s flats and is now scaling the crater’s western rim, on its way to explore new and disparate Mars landscapes. Late last month, however, the rover paused to take in the grand…

China launches 3 astronauts to Tiangong space station on Shenzhou 19 mission (video)

NeRD

China’s next human spaceflight mission is on its way into orbit. A Long March 2F rocket topped with the Shenzhou 19 crew spacecraft lifted off from the Jiuquan Satellite Launch Center today (Oct. 19) at 4:27 p.m. EDT (2027 GMT; 4:27 a.m. Oct. 30 Beijing time), rising into a night sky above the spaceport. Aboard are commander Cai Xuzhe, 48, who was a member of the Shenzhou 14 mission, and rookie astronauts Song Lingdong, 34, a former air force pilot, and Wang Haoze, also 34, a spaceflight engineer. Shenzhou 19…
