Chrome already has the ability to mute auto-playing content but you can either have it on or off. So the feature will either block all auto-playing content or none at all. Google feels that there should be a middle ground which is why the latest version of Google Chrome has the ability to learn your browser preferences before deciding which sites to mute automatically.

It’s never a good experience when you open a link or land on a website and it starts auto-playing content immediately. Google says that a significant number of auto-playes in Chrome are paused, muted or have their tab closed within six seconds if they’re unwanted.

However, there are instances in which you would want content to start playing right away, such as a live stream or a playlist. You wouldn’t want to manually unmute or play the content every single time.

That’s why Chrome desktop is getting a new policy to block unwanted auto-plays. Chrome will learn your browsing preferences and if you don’t have a browsing history, it will allow autoplay for more than 1,000 sites where it sees the highest percentage of visitors play media with sound.

As you browse the web, that list is going to change as Chrome learns and enables auto-play on sites that you play media with sound during most of your visits and disables it on sites where you don’t. This just turns the auto-play muting feature into a more personalized and predictable tool.

The new policy has been implemented in the latest version of Chrome which is out now.

NASA’s latest mission to Mars, Insight, is set to launch early Saturday morning in pursuit of a number of historic firsts in space travel and planetology. The lander’s instruments will probe the surface of the planet and monitor its seismic activity with unprecedented precision, while a pair of diminutive cubesats riding shotgun will test the viability of tiny spacecraft for interplanetary travel.

Saturday at 4:05 AM Pacific is the first launch opportunity, but if weather forbids it, they’ll just try again soon after — the chances of clouds sticking around all the way until June 8, when the launch window closes, are slim to none.

Insight isn’t just a pretty name they chose; it stands for Interior Exploration using Seismic Investigations, Geodesy and Heat Transport, at least after massaging the acronym a bit. Its array of instruments will teach us about the Martian interior, granting us insight (see what they did there?) into the past and present of Mars and the other rocky planets in the solar system, including Earth.

Bruce Banerdt, principal investigator for the mission at NASA’s Jet Propulsion Laboratory, has been pushing for this mission for more than two decades, after practically a lifetime working at the place.

“This is the only job I’ve ever had in my life other than working in the tire shop during the summertime,” he said in a recent NASA podcast. He’s worked on plenty of other missions, of course, but his dedication to this one has clearly paid off. It was actually originally scheduled to launch in 2016, but some trouble with an instrument meant they had to wait until the next launch window — now.

Insight is a lander in the style of Phoenix, about the size of a small car, and shot towards Mars faster than a speeding bullet. The launch is a first in itself: NASA has never launched an interplanetary mission from the West coast, but conditions aligned in this case making California’s Vandenberg air base the best option. It doesn’t even require a gravity assist to get where it’s going.

“Instead of having to go to Florida and using the Earth’s rotation to help slingshot us into orbit… We can blast our way straight out,” Banerdt said in the same podcast. “Plus we get to launch in a way that is gonna be visible to maybe 10 million people in Southern California because this rocket’s gonna go right by LA, right by San Diego. And if people are willing to get up at four o’clock in the morning, they should see a pretty cool light show that day.”

The Atlas V will take it up to orbit and the Centaur will give it its push towards Mars, after which it will cruise for six months or so, arriving late in the Martian afternoon on November 26 (Earth calendar).

Its landing will be as exciting (and terrifying) as Phoenix’s and many others. When it hits the Martian atmosphere, Insight will be going more than 13,000 MPH. It’ll slow down first using the atmosphere itself, losing 90 percent of its velocity as friction against a new, reinforced heat shield. A parachute takes off another 90 percent, but it’ll still be going over 100 MPH, which would make for an uncomfortable landing. So a couple thousand feet up it will transition to landing jets that will let it touch down at a stately 5.4 MPH at the desired location and orientation.

After the dust has settled (literally) and the lander has confirmed everything is in working order, it will deploy its circular, fanlike solar arrays and get to work.

Robot arms and self-hammering robomoles

Insight’s mission is to get into the geology of Mars with more detail and depth than ever before. To that end it is packing gear for three major experiments.

SEIS is a collection of six seismic sensors (making the name a tidy bilingual, bidirectional pun) that will sit on the ground under what looks like a tiny Kingdome and monitor the slightest movement of the ground underneath. Tiny high-frequency vibrations or longer-period oscillations, they should all be detected.

“Seismology is the method that we’ve used to gain almost everything we know, all the basic information about the interior of the Earth, and we also used it back during the Apollo era to understand and to measure sort of the properties of the inside of the moon,” Banerdt said. “And so, we want to apply the same techniques but use the waves that are generated by Mars quakes, by meteorite impacts to probe deep into the interior of Mars all the way down to its core.”

The heat flow and physical properties probe is an interesting one. It will monitor the temperature of the planet below the surface continually for the duration of the mission — but in order to do so, of course, it has to dig its way down. For that purpose it’s installed with what the team calls a “self-hammering mechanical mole.” Pretty self-explanatory, right?

The “mole” is sort of like a hollow, inch-thick, 16-inch-long nail that will use a spring-loaded tungsten block inside itself to drive itself into the rock. It’s estimated that it will take somewhere between 5,000 and 20,000 strikes to get deep enough to escape the daily and seasonal temperature changes at the surface.

Lastly there’s the Rotation and Interior Structure Experiment, which actually doesn’t need a giant nail, a tiny Kingdome, or anything like that. The experiment involves tracking the position of Insight with extreme precision as Mars rotates, using its radio connection with Earth. It can be located to within about four inches, which when you think about it is pretty unbelievable to begin with. The way that position varies may indicate a wobble in the planet’s rotation and consequently shed light on its internal composition. Combined with data from similar experiments in the ’70s and ’90s, it should let planetologists determine how molten the core is.

“In some ways, InSight is like a scientific time machine that will bring back information about the earliest stages of Mars’ formation 4.5 billion years ago,” said Banerdt in an earlier news release. “It will help us learn how rocky bodies form, including Earth, its moon, and even planets in other solar systems.”

In another space first, Insight has a robotic arm that will not just do things like grab rocks to look at, but will grab items from its own inventory and deploy them into its workspace. Its little fingers will grab handles on top of each deployable instrument and grab it just like a human might. Well, maybe a little differently, but the principle is the same. At nearly 8 feet long, it has a bit more reach than the average astronaut.

Cubes riding shotgun

One of the MarCO cubesats.

Insight is definitely the main payload, but it’s not the only one. Launching on the same rocket are two cubesats, known collectively as Mars Cube One, or MarCO. These “briefcase-size” guys will separate from the rocket around the same time as Insight, but take slightly different trajectories. They don’t have the control to adjust their motion and enter an orbit, so they’ll just zoom by Mars right as Insight is landing.

Cubesats launch all the time, though, right? Sure — into Earth orbit. This will be the first attempt to send Cubesats to another planet. If successful there’s no limit to what could be accomplished — assuming you don’t need to pack anything bigger than a breadbox.

The spacecraft aren’t carrying any super-important experiments; there are two in case one fails, and both are only equipped with UHF antennas to send and receive data, and a couple low-resolution visible-light cameras. The experiment here is really the cubesats themselves and this launch technique. If they make it to Mars, they might be able to help send Insight’s signal home, and if they keep operating beyond that, it’s just icing on the cake.

You can follow along with Insight’s launch here; there’s also the traditional anthropomorphized Twitter account. We’ll post a link to the live stream as soon as it goes up.
