SpaceX stacks 2nd Starship launch tower in Texas (photos)

NeRD

SpaceX is gearing up for more-frequent launches of its Starship megarocket. The company currently sends Starship, the biggest and most powerful rocket ever built, aloft from an orbital launch mount at Starbase, its site near the South Texas border city of Brownsville. But SpaceX is working to install a second launch pad at the facility, and it recently notched a big milestone toward this goal. “Second launch tower stacked as the newest addition to Starbase,” the company announced via X on Wednesday (Aug. 21), in a post that featured three…

These two Dragons are getting ready to spread their wings. SpaceX just gave us a look at the Crew Dragon capsules that will fly on the Polaris Dawn and Crew-9 astronaut missions, which are set to launch on Aug. 26 and Sept. 24, respectively. “Double Dragons readying for flight ahead of the Polaris Dawn and Crew-9 human spaceflight missions,” the company wrote in an X post on Wednesday (Aug. 21) that featured two photos of the capsules, side by side in a processing facility on Florida’s Space Coast. Polaris Dawn…

What happens if you throw a star at a black hole? Things get messy (video)

NeRD

“What happens when you throw a star at a black hole?” It’s not a question we can physically answer here on Earth.  Thankfully, actual black holes and stars can’t be smashed together in the lab! However, scientists can use advanced supercomputer modeling to simulate a black hole ripping apart and devouring a star in a so-called “tidal disruption event” or “TDE.” Doing just that, a team of researchers led by Danel Price from Monash University has discovered that the answer to our opening question is “things get messy.”  “Black holes…

Scientists collect high-resolution images of the North Star’s surface for 1st time

NeRD

In our solar system, scattered across one of Earth’s verdant mountains, six eggshell-white telescopes gaze into the deep universe. As one cohesive hive, the domed structures collect cosmic light to guide modern astronomers exploring space — and it is thanks to this hive that we now have a brilliant new perspective on the light that guided astronomers of the past: the North Star. Our visual knowledge of the current North Star (because of Earth’s axial wobble, the title passes to different stars over the eons) runs deep. Artists, old and…

‘Star Wars: The Acolyte’ canceled after just 1 season

NeRD

‘The Acolyte’ had a bumpy journey through marketing and release on the small screen, to say the least.  With a number of sites and permanently disgruntled fans that decided ages ago the series would be terrible, (likely false) cancellation rumors started to pile up even before its season 1 premiere. Now, roughly one month after a strong season finale that capped a notable second half of the season, Deadline and Variety are reporting that Disney and Lucasfilm have decided not to move forward with season 2. No matter how you…

Some rocky exoplanets could have huge amounts of water in their molten cores

NeRD

As much as 95% of an exoplanet’s water could be trapped forever deep inside its iron core, transforming what we thought we knew about water worlds and potentially rendering them even more habitable than we realized. “Planets are much more water-abundant than previously assumed,” said Caroline Dorn, who is professor of exoplanets at ETH Zurich in Switzerland, in a statement. When planets are born by accreting rubble and enduring collisions with other protoplanets, they become so hot that their entire surface is covered in an ocean of molten rock. This…

SpaceX Polaris Dawn crew lands at space center ahead of 1st-ever private spacewalk mission (photos, video)

NeRD

CAPE CANAVERAL, Florida — Members of the Polaris Dawn mission landed at NASA’s Kennedy Space Center (KSC) today (Aug. 19), with as little as a week until their launch to space. Polaris Dawn is the second privately crewed SpaceX mission funded by philanthropist billionaire Jared Isaacman, and the first of at least three launches he hopes to fly under the “Polaris” program. The launch stands as a follow-up to Isaacman’s 2021 Inspiration4 mission, in which he and three other private citizens launched on the first-ever civilian-only spaceflight. Inspiration4 helped raise $250…

Telescopes capture Jupiter-bound JUICE probe during historic Earth-moon flyby (photos)

NeRD

For avid skywatchers around the world, this week begins with trying to get a glimpse of the Jupiter-bound JUICE spacecraft that’s set to swing past both the moon and Earth over the span of just one day — a combination scientists have deemed to be the world’s first. The European Space Agency (ESA) launched JUICE in April last year to explore Jupiter and three of its biggest moons — Ganymede, Callisto and Europa, all of which are thought to contain oceans of liquid water beneath their icy shells. The spacecraft’s…

What is Weyland-Yutani? The ‘Alien’ universe megacorporation explained

NeRD

In the vast sphere of multinational global conglomerates operating with honesty, trust and transparency, the Weyland-Yutani Corporation of the “Alien” franchise would rank at the absolute slimy bottom. This fictional megalomaniacal enterprise had its greedy tentacles into everything from robotics, biotechnology, cybernetics, AI, and interstellar mining, to terraforming, off-world colonization, medical research and developing weapons using extraterrestrial DNA gathered around the galaxy.   But what are the ambitious beginnings of this notorious San Francisco-based company, how have its personnel, facilities, spaceships and machines been integrated into the “Alien” universe and…
