Hayabusa2’s 2031 Landing Plan Faces an Unexpected Asteroid Nightmare

Hayabusa2’s 2031 Landing Plan Faces an Unexpected Asteroid Nightmare

On December 6, 2020, the Hayabusa2 spacecraft dropped off pristine samples from asteroid Ryugu in the Australian outback, becoming the world’s second asteroid sample return mission, after the first Hayabusa mission returned dusty samples from asteroid Itokawa in 2010. But Hayabusa2 still has more to offer.

That same spacecraft is currently on its way to another distant space rock, aiming to snag more samples to help scientists compile the solar system’s origin story. Recent observations of the asteroid, however, reveal that Hayabusa2 might not be able to touch down on its new target.

Asteroid 1998 KY26 is a small, lumpy near-Earth object thought to contain about a million gallons of water. It rotates so quickly that a day on the rock ends almost as soon as it begins, according to NASA. Hayabusa2 is set to rendezvous with the asteroid in 2031 as part of its extended mission to collect more dust and rock straight from the source.

Now, using multiple observatories around the world, astronomers gathered more data on Hayabusa2’s new target and found that it is nearly three times smaller and spinning much faster than originally thought, according to a new paper published in Nature Communications.

Not clear for landing

The researchers behind the new paper combined the recent observations with previous radar data, revealing that the asteroid is a mere 36 feet (11 meters) wide, as opposed to 98 feet (30 meters). What’s more, the asteroid is spinning about twice as fast as earlier data suggested.

“We found that the reality of the object is completely different from what it was previously described as,” Toni Santana-Ros, a researcher from the University of Alicante, Spain, and lead author of the new paper, said in a statement. “One day on this asteroid lasts only five minutes!”

Hayabusa2’s first target measured at nearly 3,000 feet (900 meters) wide. The spacecraft landed on asteroid Ryugu on February 22, 2019, for the first time, then returned for a second touchdown in July 2019 to collect subsurface samples from a crater it had created with its first landing. Shortly before dropping off its samples on Earth, Japan’s space agency (JAXA) announced an extension to Hayabusa2’s mission and a lucky second target.

A bigger challenge awaits

Unlike its first target, however, Hayabusa2’s second landing will prove far more challenging due to the asteroid’s small size and fast rotation. The team behind the new study used the European Southern Observatory’s Very Large Telescope and other instruments to observe 1998 KY26 in preparation for the mission’s upcoming encounter.

“The amazing story here is that we found that the size of the asteroid is comparable to the size of the spacecraft that is going to visit it! And we were able to characterize such a small object using our telescopes, which means that we can do it for other objects in the future,” Santana-Ros said. “Our methods could have an impact on the plans for future near-Earth asteroid exploration or even asteroid mining.”

This has the makings of a very interesting rendezvous! Now we just have to wait—impatiently—for 2031 to arrive.

By providing a needed security patch to an older version of iOS last month, Apple tacitly—but unofficially—acknowledged that avoiding the Liquid Glass aesthetic is a valid choice.

Now, according to anonymous sources who spoke to Bloomberg’s Mark Gurman, an upcoming update will address problems with Liquid Glass in macOS 26. If you haven’t updated because you hate it, or are worried the design flaws make it unusable, you are seen.

Gurman writes that Apple “is preparing what people internally consider to be a ‘slight redesign’ for macOS 27,” and that the company is looking to fix, “shadows and transparency quirks.”

Gurman’s sources sound a bit defensive, however. They tell him the Liquid Glass update “didn’t necessarily suffer from design problems,” but instead had “a not-completely-baked implementation from Apple’s software engineering team.” The fixes, then, are supposed to “make Liquid Glass look the way Apple’s design team intended it to from the start.” Got it? The designers thought everything through from the beginning, but the artless neanderthals who built their designs into software—this thinking goes—let them down.

My first impression was that it was overly generous of Gurman to give voice to this framing of the Liquid Glass story, but I have to admit that it’s also a genuinely plausible explanation for just how hated the design scheme ended up being.

For instance, while Apple has already chipped away at some of the bigger problems, Tahoe shipped with some issues that were beyond annoying and actually interfered with usability, particularly for low vision people. Before the 26.3 update in February, as OS X Daily noted, choosing the option to reduce transparency “would leave considerable transparent effects, including in sidebars, headers, titlebars, search boxes, and more, leading to situations where text would overlap and interface elements would be washed out with blurry colors and interface elements.”

Then again, some designs were heavily criticized on an aesthetic basis, not as bad implementation. There’s probably no bigger Apple fan than John Gruber of Daring Fireball, and his take on the redesign of some of the icons was scorching: “I don’t think the old icons for these apps from MacOS 15 were particularly good — Apple has mostly lost its “icons look cool” game. But the new ones in MacOS 26 Tahoe are objectively terrible.”

Gurman has claimed in the past that Liquid Glass is sort of a long game, rolled out in advance of the release of the 20th anniversary iPhone, which he expects to be a huge design milestone for Apple. Supposedly, that phone’s overall vibe will benefit from Liquid Glass. When all is revealed, maybe the world will agree.

In the meantime, macOS is getting some tweaks, and we should expect, Gurman says, “more of a cleanup and refinement effort aligned with the company’s wider push to polish its software this year.”

After three people died on a cruise ship struck by a hantavirus, authorities are actively tracking down 29 people who had left the ship. They’re trying to trace the spread of the virus. It’s a long, arduous, global process to find and notify people who might be at risk of infection.

Hey, wasn’t there supposed to be an app for that?

Contact-tracing apps were a global effort starting in 2020 during the Covid-19 pandemic. Enabled by phone companies like Apple and Google, contact tracing was designed to use Bluetooth connections to detect when people had come in contact with someone who had or would later test positive for Covid and report as much. It didn’t do much to solve the spread of the pandemic, but tracking the virus became more effective at least. The same process wouldn’t go well for the hantavirus problem.

“There is no use of apps for this hantavirus outbreak,” Emily Gurley, an epidemiologist at Johns Hopkins University, wrote in an email response to WIRED. “The number of cases are small, and it’s important to trace all contacts exactly to stop transmission.”

On a smaller scale of infection like this, officials have to start at the source (an infected individual), then go person-by-person, confirming where they went and who they might have come into contact with. Data collected by apps from a broad swath of devices would not be anywhere close to accurate enough to give a good idea of where the virus might have hitchhiked to next.

Contact tracing on a wider scale, like, say, a global pandemic, is less about tracking the individual infections and more about understanding what parts of the population might be affected, giving people the opportunity to self-quarantine after exposure. But that depends on how people choose to respond, and how the technology is utilized by public emergency systems. During the Covid pandemic, contact-tracing via apps tended to work better in more carefully managed European countries, but did not slow the spread in the US.

Making devices accessible to that kind of proximity information has also brought all sorts of concerns about privacy, given that the technology would require always-on access to work properly. Contact tracing also struggled to maintain accuracy, and in some cases could be providing false negatives or positives that don’t help further real information about the spread of the virus.

Especially in the case of something like the Hantavirus, where every person on that cruise ship can theoretically be directly tracked and contacted, it’s better to do that process the hard way.

“During small but highly fatal outbreaks, more precision is required,” Gurley wrote.
