Mars helicopter bound for the Red Planet takes to the air for the first time – TechCrunch

Published

on

The Mars 2020 mission is on track for launch next year, and nesting inside the high-tech new rover heading that direction is a high-tech helicopter designed to fly in the planet’s nearly non-existent atmosphere. The actual aircraft that will fly on the Martian surface just took its first flight and its engineers are over the moon.

“The next time we fly, we fly on Mars,” said MiMi Aung, who manages the project at JPL, in a news release. An engineering model that was very close to final has over an hour of time in the air, but these two brief test flights were the first and last time the tiny craft will take flight until it does so on the distant planet (not counting its “flight” during launch).

“Watching our helicopter go through its paces in the chamber, I couldn’t help but think about the historic vehicles that have been in there in the past,” she continued. “The chamber hosted missions from the Ranger Moon probes to the Voyagers to Cassini, and every Mars rover ever flown. To see our helicopter in there reminded me we are on our way to making a little chunk of space history as well.”

A helicopter flying on Mars is much like a helicopter flying on Earth, except of course for the slight differences that the other planet has a third less gravity and 99 percent less air. It’s more like flying at 100,000 feet, Aung suggested.

It has its own solar panel so it can explore more or less on its own

The test rig they set up not only produces a near-vacuum, replacing the air with a thin, Mars-esque CO2 mix, but a “gravity offload” system simulates lower gravity by giving the helicopter a slight lift via a cable.

It flew at a whopping two inches of altitude for a total of a minute in two tests, which was enough to show the team that the craft (with all its 1,500 parts and four pounds) was ready to package up and send to the Red Planet.

“It was a heck of a first flight,” said tester Teddy Tzanetos. “The gravity offload system performed perfectly, just like our helicopter. We only required a 2-inch hover to obtain all the data sets needed to confirm that our Mars helicopter flies autonomously as designed in a thin Mars-like atmosphere; there was no need to go higher.”

A few months after the Mars 2020 rover has landed, the helicopter will detach and do a few test flights of up to 90 seconds. Those will be the first heavier-than-air flights on another planet — powered flight, in other words, rather than, say, a balloon filled with gaseous hydrogen.

The craft will operate mostly autonomously, since the half-hour round trip for commands would be far too long for an Earth-based pilot to operate it. It has its own solar cells and batteries, plus little landing feet, and will attempt flights of increasing distance from the rover over a 30-day period. It should go about three meters in the air and may eventually get hundreds of meters away from its partner.

Mars 2020 is estimated to be ready to launch next summer, arriving at its destination early in 2021. Of course, in the meantime, we’ve still got Curiosity and Insight up there, so if you want the latest from Mars, you’ve got plenty of options to choose from.

Google will soon default to blurring explicit image search results

Published

on

Enlarge / Google’s new “Blur” setting for SafeSearch will soon be the default, blurring explicit images unless you’re logged in and over 18.

Google has debuted a new default SafeSearch setting, somewhere between “on” and “off,” that automatically blurs explicit images in search results for most people.

In a blog post timed to Safer Internet Day, Google outlined a number of measures it plans to implement to “protect democracies worldwide,” secure high-risk individuals, improve password management, and protect credit card numbers. Tucked into a series of small-to-medium announcements is a notable change to search results, Google’s second core product after advertising.

A new setting, rolling out “in the coming months,” “will blur explicit imagery if it appears in Search results when SafeSearch filtering isn’t turned on,” writes Google’s Jen Fitzpatrick, senior vice president of Core Systems & Experiences. “This setting will be the new default for people who don’t already have the SafeSearch filter turned on, with the option to adjust settings at any time.”

Google’s explanatory image (seen above) shows someone logged in and searching for images of “Injury.” A notice shows that “Google turned on SafeSearch blurring,” which “blurs explicit images in your search results.” One of the example image results—”Dismounted Complex Blast Injury (DCBI)” from ResearchGate—is indeed quite explicit, as far as human viscera and musculature goes. Google provides one last check if you click on that blurred image: “This image may contain explicit content. SafeSearch blurring is on.”

Explicit images, such as the "blast injury" shown in Google's example, will be blurred by default in Google search images, unless a user is over 18, signs in, and turns it off.

If you click “View image,” you see life’s frail nature. If you click “Manage setting,” you can choose between three settings: Filter (where explicit results don’t show up at all), Blur (where both blurring and are-you-sure clicks occur), and Off (where you see “all relevant results, even if they’re explicit”).

Signed-in users under the age of 18 automatically have SafeSearch enabled, blocking content including “pornography, violence, and gore.” With this change, Google will automatically be blurring explicit content for everybody using Google who doesn’t log in, stay logged in, and specifically ask to show it instead. It’s a way to prevent children from getting access to explicit images, but also, notably, a means of ensuring people are logged in to Google if they’re looking for something… very specific. An incognito window, it seems, just won’t do.

Google turned on SafeSearch as its default for under-18 users in August 2021, having been pressured by Congress to better protect children across its services, including search and YouTube.

OnePlus takes on the iPad with the OnePlus Pad

Published

on

Android tablets are on their way back, and one of Android’s biggest manufacturers (we’re talking about OnePlus parent company BBK) is bringing an Android tablet to the US for the first time. Say hello to the OnePlus Pad, an 11.61-inch tablet with an optional keyboard and stylus. We don’t know how much it costs, so don’t ask. There’s also no hard release date, but preorders start in April.

What we do know are the specs. The 11.61-inch display is a 144 Hz LCD, with a resolution of 2800×2000. That’s an aspect ratio of 7:5, or a bit wider than a 4:3 display, which OnePlus claims is a “book-like” aspect ratio. The SoC is a MediaTek Dimensity 9000. That’s a rarity in the US, but it’s basically a generic ARM design for 2022 flagship phones, with one 3.05 GHz ARM Cortex X2 CPU, three A710 CPUs, and four A510 CPUs. It’s a 4 nm chip with an ARM Mali-G710 MC10. You also get 8GB of RAM (there’s an option for 12GB), 128GB of UFS 3.1 storage, and a 9510 mAh battery. This is not in the super-flagship tablet territory and should (hopefully) come with an affordable price tag.

As always, OnePlus’ trademark quick-charging is here, and it’s 67 W. On a tiny phone battery, that kind of charging will usually take a phone from 0-100 in around a half hour, but with a big tablet battery, a full charge still takes “just over 60 minutes.” In the fine print, OnePlus actually gives a warning against any repair attempts, saying, “The battery has been especially encrypted for safety purposes. Please go to an official OnePlus service center to repair your battery or get a genuine replacement battery.” I’ve never heard of a battery being “encrypted” before, but I think they mean there is a serial number check in the firmware somewhere and that it will presumably refuse to work if you replace it. As for the possibility of an “official OnePlus service center” actually existing, there is a business finder on the OnePlus India website, but not one in the US, so it’s looking like mail-in service only.

The tablet is made up of an aluminum unibody that weighs 555 g. The sides are rounded over, which should make it feel comfortable to hold. It comes with four speakers, a USB-C port on the right side, and a set of three pogo pins on the bottom for the keyboard. The back has a circular camera bump that makes it look like a close cousin of the OnePlus 11, and it holds a single 13 MP camera. We also hope you like green, because that appears to be the only color.

There’s no fingerprint sensor at all. There is a cutout that looks like it might be a fingerprint sensor, but we guess that’s just a radio signal window. There’s also no GPS listed on the spec sheet. We know next to nothing about the “OnePlus Magnetic Keyboard” and “OnePlus Stylo” pen. The keyboard has a small trackpad that supports swiping. The pen has a 2 ms response time, which sounds pretty good. That’s about it. Presumably we’ll know more in April.

Report: Sonos’ next flagship speaker will be the spatial audio-focused Era 300

Published

Sonos will release a new flagship speaker “in the coming months,” according to a report Monday from The Verge. The publication said this will be called the Era 300 and that Sonos is prioritizing the device’s spatial audio capabilities.

The Verge claimed that Sonos is aiming for the Era 300 to be its most accurate speaker yet. It pointed to a heightened focus on making Dolby Atmos content shine, as well as improving music using spatial audio. According to The Verge, the Era 300 will be a “multidirectional speaker built to get the most from spatial audio” by way of a “completely re-architected acoustic design.”

We don’t have deeper details, like specs or pricing. However, Wi-Fi 6 and a USB-C port are apparently “likely,” and Bluetooth support is also possible. According to The Verge, Sonos has at least looked into including all these features on the Era 300.

The Verge first started reporting about the Era 300, codenamed Optimo 2, in August. This week, it identified more evidence of the speaker’s development in the form of two recent documents from TV mount-maker Sanus that name the Era 300.

In August, The Verge, citing “early, work-in-progress images” it reportedly viewed, said that Sonos’ upcoming flagship speaker would include “an arsenal of drivers, including several that fire in different directions from beneath the shell between the front speaker grille and backplate.” It also suggested a more beefed-up product, with twice the RAM and eight times the flash memory as the highest-specced Sonos speaker today.

The Verge also claimed this week that Sonos is working on a lower-priced Era 100, suggesting that it could include Dolby Atmos support and serve as a follow-up to the Sonos One, which has a $179 MSRP as of writing.

Should the Era 300 truly debut soon, it will face competition from Apple’s recent $299, full-sized HomePod revival, which supports spatial audio with Dolby Atmos with Apple apps and Apple TV 4K. Besides superior audio quality, a new Sonos flagship could score points with shoppers by playing better with non-Apple devices, such as by including Bluetooth and by besting the Apple speaker’s Wi-Fi 4 support.
