China has plans to launch reusable space rockets to compete with the likes of SpaceX and Blue Origin.

The Chinese Aerospace Science and Technology Corporation (CASC), the leading builder of Chinese space launch rockets, announced that its Long March (CHang Zheng in Chinese) LM-8 space rocket will launch in 2020.

Like the SpaceX Falcon and Falcon Heavy, the LM-8’s first stage will be reusable, using leftover fuel to land vertically. This shouldn’t come as a surprise, given that CASC has previously promised to make all its rockets reusable by 2035.

The LM-8 is a medium-sized space launch vehicle, capable of carrying 7.7 tons to low-earth orbit. It shares the same first stage core as the larger Long March 7 (which is China’s newest man-rated rocket), but compared to the Long March 7, it has only two K2 liquid rocket boosters. Once the LM-8’s second stage separates to enter orbit, the LM-8’s first stage will descend back to the ground by carefully burning remaining fuel to maneuver onto the landing pad, with the aid of grid fins. In the last moments of descent, landing struts will unfold from the bottom of the rocket to ensure a smooth touchdown. The boosters will separate and parachute back to the ground.

The tech LM-8 shares with the Long March 7 could mean that the LM-7—and other larger Chinese space launch rockets—could be retrofitted with resusablity. Additionally, CASC is planning to test grid fins on a Long March 4B rocket next year to refine the technology. Test launch of a reusable, smaller Long March 6 rocket is planned for 2020. Success in these tests will fit into CASC’s plan to make all its Long March rockets—from the super heavy “moon rocket” Long March 9 to the Long March 6—reusable by 2035.

This development is just one step in private Chinese companies’ larger path toward a reusable space launch market. Linkspace’s New Line 1 rocket, which will also land vertically via its reusable first stage, has plans for a 2020 flight. And CASC and its rival CASIC both plan to have their spaceplanes flying in 2020.

Keep Yourself from Binging YouTube with the New ‘Take a Break’ Feature

Keep Yourself from Binging YouTube with the New ‘Take a Break’ Feature

https://ift.tt/2Kp163X

YouTube videos: You can never watch just one. It’s not your fault. YouTube does a great job of keeping you engaged by constantly offering tailor-made suggestions (and an aggressive autoplay system).

Now, thanks to a new update, YouTube is finally admitting that too much of a good thing can be bad. Here’s how to use the service’s new “Remind me to take a break” feature to curb your YouTube addiction.

The first thing you’ll need to do is make sure you have the latest version of YouTube for iOS or Android. Before you get distracted by the latest Marvel fan theory (or whatever YouTube’s algorithm think you’re interested in), tap on your profile pic in the top right corner. Tap on Settings, and you should see a new option titled, “Remind me to take a break.”

Tap on this option, and you’ll be able to set YouTube to send you a friendly reminder to stop staring at your phone after a set amount of time (the options range from 15 minutes to two hours). You can now go back watching Fortnite videos (or cooking guides, or whatever else you might be into), knowing that YouTube has your back—unless you ignore its notification because you’re too busy watching a video.

Stare In Awe, Disbelief, and Envy at This Console-Covered Boombox for Gamers

Stare In Awe, Disbelief, and Envy at This Console-Covered Boombox for Gamers

https://ift.tt/2Knx8xj

YouTube’s My Mate VINCE has a knack for wiring modern video game consoles to old-school TVs. After perfecting his skills, he’s hacked together what is undoubtedly his greatest, most absurd creation: a resurrected boombox that lets gamers play their favorite titles anywhere they’re strong enough to carry this monstrosity.

At the core of this portable is an old-school Radio Shack boombox that features a tiny, built-in, black-and-white CRT TV: a feature that would have blown my mind when I was a kid. Strapped to the boombox with zip ties is also a Nintendo Switch, an SNES Classic Edition, a PSTV, a Wii Mini, and all of the cables and digital-to-analog convertor boxes needed to wire the modern hardware into the stereo’s antique RF input.

As portable gaming devices go, this one barely qualifies, particularly after you add in all the extra weight of the clunky battery packs needed to keep everything powered. Maybe just buy a 3DS instead?

Decades-old data helps confirm Europa is geysering water into space

Decades-old data helps confirm Europa is geysering water into space

https://ift.tt/2KmjjPC

Over the past few years, the Hubble Space Telescope has observed what looked to be plumes of water vapor shooting from the surface of one of Jupiter’s moons, Europa. Now, scientists have looked over decades-old data from Galileo and discovered that the spacecraft actually got close to one of these plumes during a flyby. This is the first up-close measurement we have of these eruptions, and the best evidence yet that Jupiter’s fourth-largest moon is indeed shooting water into space. The findings are detailed in an article in Nature Astronomy, which was released today.

Scientists believe that Europa has a thick icy crust, beneath which lies a salt water global ocean. The plumes of water vapor likely originate from this ocean. Galileo flew by the Jovian moon eleven times during its mission, which lasted from 1995 to 2003. The hope was that these flybys contained data about these plumes that scientists hadn’t yet discovered.

They were in luck. The team, led by Xianzhe Jia, zeroed in one particular flyby of Europa on December 16th, 1997 in which the spacecraft was just 206 km (128 miles) above the moon’s surface. During this encounter, scientists noticed a sudden drop in Europa’s magnetic field at a spot above the equator. They analyzed and modeled the data to explain this discrepancy. The most logical explanation is that Galileo flew directly through one of Europa’s water vapor plumes on this flyby. No other flybys picked up evidence of these eruptions, though this particular one was the closest that the spacecraft came to Europa’s surface.

This news is exciting for multiple reasons. First, it means that Europa could play host to life beneath its icy crust. After all, water is crucial for life on Earth, so scientists think our best bet for finding it on other planets is to locate sources of liquid water. Second, these plumes mean that a spacecraft could have easy access to Europa’s water without having to drill through its ice crust. NASA’s Europa Clipper spacecraft, currently scheduled to launch in 2022, is designed to fly closer than we’ve ever gotten to the Jovian moon. Now that we have this unearthed Galileo data, scientists can better plot the trajectory of the spacecraft to ensure we gather more data on these plumes, and Europa’s subsurface ocean as a result.

Mesh Wifi gear from different companies could soon work together

Mesh Wifi gear from different companies could soon work together

https://ift.tt/2wG9mL4


AOL

Until now, ensuring full WiFi coverage of your home with a mesh network has typically meant buying multiple routers or access points from one company. But with a new mesh standard coming into play, you’ll have more choice in how to build out your network because nodes from different companies will theoretically be compatible with each other. With its EasyMesh program, the WiFi Alliance wants to make sure mesh routers from various manufacturers can speak to each other — just as it used its WiFi certification to ensure wireless access standards.

EasyMesh is purely about bringing together disparate devices, and manufacturers can still add unique features and improve specs to help their routers stand out from the pack, the WiFi Alliance’s Kevin Robinson told PC World. So, if you have an existing mesh network and one company develops vastly superior security measures, you might replace only the router connected to your modem instead of your entire network. Robinson also noted that EasyMesh is a software standard, so manufacturers can update firmware on existing routers to meet the certification.

Routers that support the standard might have an EasyMesh logo on the box, as The Verge notes, making it clear that they’re compatible. However, manufacturers don’t have to sign up. Google might decide it’s more advantageous to keep Google WiFi a closed shop and ensure owners can only repair or extend their networks with its own nodes, for example.

EasyMesh seems like it’ll be more of a boon to smaller companies (at least to begin with) than Google and Eero, who might find it easier to lock buyers in to their proprietary networks because they’re better-known brands. Among those supporting EasyMesh from the outset are AirTies, ARRIS, and ASSIA. Eventually, though, EasyMesh could help drive down prices of mesh networks if enough companies adopt it.

Didi Chuxing receives permit to test self-driving cars in California

Didi Chuxing receives permit to test self-driving cars in California

You might not hail a ride from China’s Didi Chuxing unless you visit Mexico, but there’s still a real chance you’ll see its vehicles on the road. California’s Department of Motor Vehicles has issued an autonomous vehicle testing permit to Didi’s American research wing, clearing it to operate self-driving cars as long as there’s a safety driver. The move comes slightly over a year after Didi opened its US research lab, suggesting the company isn’t wasting much time putting its technology on the road.

Didi is getting its permit just weeks after California introduced new rules around self-driving permits, the brunt of which focused on completely driverless vehicles. A total of 53 companies were part of this new permit batch, though many of them are no strangers to the technology. In addition to established car brands like BMW, Ford, GM, Honda, Tesla, Toyota and Subaru, you’ll also see tech giants like Apple, Lyft, NVIDIA and Samsung. Uber isn’t on the list as it reviews its autonomous driving project following the fatal crash in Arizona.

It’s unlikely that Didi will offer full-fledged autonomous ride hailing in the US. Whether or not the government’s wariness around Chinese businesses would hurt its chances, it would face the same problem Uber did in China — it’d have to face rivals with a clear home turf advantage. Whatever the company learns in the US will probably only be used outside of the country.

Apple now has more than 50 autonomous cars on the road

Apple now has more than 50 autonomous cars on the road

https://ift.tt/2wEJgb2


Apple

Apple has more than doubled the number of its self-driving cars, the California Department of Motor Vehicles (DMV) has confirmed. Since obtaining a permit to test autonomous vehicles, Apple’s fleet size has steadily risen — from a scant three test cars, to 27 in January, and now, 55 intelligent machines. Should the program remain on course, consumers could be chilling out in the driver’s seat by 2019.

The intake is accompanied by 83 drivers who will be testing the vehicles. At this stage, Apple hasn’t been authorized to test self-driving cars independent of human supervision; for that, the company will need to submit a separate permit to the DMV — something Waymo did last month. The DMV also revealed that a second unnamed company had requested approval to begin driverless testing, but hasn’t parted with any additional details.

We do know that the autonomous car scene is heating up — Tesla and Drive.Ai are lagging behind Apple, but fellow California-native GM Cruise leads the pack with 104 vehicles with self-driving capacity. Still, one of the biggest issues inherent to automated technology is safety. The recent fatal accident involving one of Uber’s self-driving prototypes — apparently due to misaligned software — couldn’t be stopped by the test driver in time.

This indicates a margin of error that’s worth considering before rushing into fully self-driving trials; before the public can accept autonomous cars as a reliable alternative, companies need to gain its trust. There’s always a risk of mechanical failure, and human error can’t be ignored, either. but if companies identified problems and developed adequate prevention measures in advance, the number of accidents could experience a remarkable drop. That might push back release schedules, but autonomous safety should be top priority.
