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.

The MacBook Pro will soon get a resolution bump, macOS beta suggests

Published

on

The seventh beta of macOS Monterey contains what appear to be references to new screen resolutions suitable for the MacBook Pro line, as discovered by MacRumors.

In a list of supported graphics resolutions within macOS, there are two new resolutions: 3,456 by 2,234 and 3,024 by 1,964. Each carries a “Retina” marker, which Apple typically only applies to its own devices’ screens.

The aspect ratio for these new resolutions is very close to the current aspect ratios on the MacBook Pro computers sold today, but they’re lower than what we currently see in the iMac line, suggesting that they aren’t for Apple’s desktops. Further, the numbers fit nicely with a move to true 2x Retina, as opposed to the scaling approach presently used for Retina displays.

It is possible that this is a mistake, but the timing is convenient. macOS Monterey is expected to launch this fall alongside new MacBook Pro models featuring custom-designed Apple silicon that would be faster successors to Apple’s much-lauded M1 chips found in lower-end Macs and the most recent refresh of the iPad Pro.

If reports in Bloomberg and elsewhere are to be believed, the new laptops would also include Mini LED displays, which provide better contrast than the display technology currently used in Mac laptops, as well as additional ports like HDMI or an SD card slot. These devices would also drop the Touch Bar, which some users like but others hate, in favor of a return to physical function keys. The 13-inch MacBook Pro would probably see reduced bezels, making it a 14-inch MacBook Pro. (A similar change replaced the 15-inch MacBook Pro with a 16-inch model a couple of years ago.)

So increased screen resolutions join a plethora of other likely changes that would make for the most significant redesign of the MacBook Pro since the first Touch Bar models in 2016.

Leaks have also pointed to an upcoming MacBook Air redesign, but that laptop is unlikely to come until later.

The Surface Duo’s two-year-old Android OS will be updated sometime this year

Published

on

If Microsoft wants to be taken seriously as an Android manufacturer, one of the things it will need to establish is a track record of reliable, on-time software updates. But as the company launches a second generation of the Surface Duo and the company’s first Android phone turns a year old, so far Microsoft has failed to impress.

The Surface Duo 1 shipped in September 2020 with Android 10, which was a full year old at the time, and Android 11 had already launched. The hope was that Microsoft would quickly update the Duo to the latest version of Android, but that never happened. Today the device is still running Android 10, which is now two years old, and Android 12 is about to ship. Microsoft has finally broken its silence about Surface Duo 1 updates, and the company tells The Verge it plans to update the device to Android 11 “before the end of this year.”

Assuming Microsoft follows through on its promise, the company’s $1,400 flagship device will be updated from a two-year-old operating system to a one-year-old operating system. Microsoft committed to three years of updates, and it has been delivering monthly security updates. But this is still worst-in-class update support, especially for the price. Samsung usually rolls out Android to its latest flagship three months after Google’s release, while OnePlus usually takes around a month—Microsoft’s one-year timeframe is really bad.

Microsoft is, at least, communicating. Before, it never really let its customers know when Android 11 would be arriving on the Surface Duo until this latest report, leaving the rumor mill to fill in the gaps. It would be nice to get a timeframe for Android 12 releases, given the latest update will be out any day now. Perhaps Microsoft’s lack of communication was due to the company just not knowing when Android 11 would be done. The Android 10 build that shipped on the original Duo had all sorts of bugs, and the company is clearly having a hard time transitioning to Android.

Perhaps some of Microsoft’s update problems were caused by the Duo 1 originally being designed for a now-canceled mobile resurrection of Windows; Microsoft was essentially forced to switch to Android later in that product’s development life. Unsurprisingly, the Windows-maker didn’t have a lot of Android OS engineers on staff at the time, and Microsoft ended up outsourcing the Duo’s OS development to a company called “Movial.” Microsoft ended up acquiring Movial just two months before the Duo’s release date, which doesn’t sound like ideal timing.

The Duo 1’s Windows DNA resulted in a device with very different underpinnings from a normal Android phone, like a “custom engineered” Microsoft UEFI instead of the normal Qualcomm one. The Duo 2 should have been designed from the start with Android as the target, so maybe things will be better for the sequel?

Windows 11 hits the Release Preview Insider channel as official release nears

Yesterday, Microsoft released a near-final build of Windows 11 to Windows Insiders in the Release Preview channel, which (as the name implies) is generally the last stop for a major new Windows version ahead of its release to the general public. The official release date for Windows 11 is October 5, but Microsoft is planning to roll it out gradually over the next few months to prevent widespread problems.

The build number in the Release Preview channel is 22000.194, the same version released to the Beta channel on September 16.

While Beta- and Dev-channel builds of Windows 11 are simply downloaded and installed like regular Windows Updates, the version in the Release Preview channel gives you the same upgrade message that will be offered to the public when Microsoft offers the Windows 11 upgrade for their PCs. This includes a system notification that users can click through to learn more about Windows 11’s new features and a special update message in Windows Update that will give you the opportunity to waive the Windows 11 upgrade and stay on Windows 10 (seen above).

Windows 10 can run on pretty much any PC that could run Windows 7 or Windows 8, but Windows 11 comes with stringent new processor and security hardware requirements that severely limit its compatibility. The most important is the CPU requirement, which generally mandates an 8th-generation Intel Core processor (introduced in late 2017) or newer or a 2nd-generation AMD Ryzen processor (introduced in mid 2018) or newer. There are only a handful of exceptions for older processors, including for Microsoft’s own Surface Studio desktop—Microsoft has the full list of Intel and AMD processors available on its documentation site.

If your PC can run it, Windows 11 includes a refreshed user interface, rescued from Microsoft’s failed “Windows 10X” project. The redesign overhauls the taskbar, Start menu, system tray, the Settings app, and Windows Explorer, as well as right-click menus and built-in apps throughout the OS. It also adds some gaming features and improvements to the Windows Subsystem for Linux, though some of these will be backported to Windows 10.
