If your iPhone storage is full and your iCloud won't back up because that's also full, Google Photos can help you free up space on your phone. Unlike iCloud, Google Photos offers free unlimited storage of compressed photos and videos. iCloud users who are running out of storage space on their iPhone can use Google Photos to free up a lot of space. Business Insider's A. C. Fowler tried Google Photos after using iCloud for five years and it allowed him to finally free up space on his 16GB iPhone 6s.

I Tried Google Photos And I'm Never Going Back To iCloud

Over the last 50 years, spacecraft have landed on over half a dozen worlds. But nowhere has proven more treacherous than the Red Planet — Mars.

------------------------------------------------------

Following is the transcript of the video:

Landing on Mars is easier said than done. Over the last 50 years, spacecraft have landed on over half a dozen worlds. Including Venus, Saturn’s moon Titan, a comet, and more. But nowhere has proven more treacherous than the Red Planet — Mars. To date, only 40% of attempted landings have been successful. But just looking at it, Mars seems pretty harmless, right? It doesn’t have toxic clouds like Venus. And there’s plenty of flat, stable places to land, unlike a comet. But here’s the thing: It’s not what you can see that’s the problem. It’s what you can’t: The atmosphere.

Mars’ atmosphere is 100 times thinner than Earth’s. Because Mars’ atmosphere is so thin, it makes parachutes less effective. 10 times less effective, in fact. So, let’s say you could skydive on Mars, and you use the same-sized parachute as on Earth. On Earth, skydivers hit the ground running at around 20 mph. But on Mars, you’d be falling at 200 mph on impact. Not good. Now, you could make your parachute larger to slow down more. And that’s partly what NASA does. For example, its Curiosity rover used the largest supersonic parachute at the time, when it landed in 2012.

But even that couldn’t slow Curiosity down, enough. To see why let’s go back to skydiving. If you wanted to slow down to the same landing speed (20 mph) on Mars as on Earth you’d need a parachute that’s 10 times wider. Or about 110 feet in diameter. Wide enough to cover the length of 2.4 school buses. Now, here’s the catch: NASA’s Curiosity rover weighs about 13 times more than the average human. Which means, to slow down to the same speed, it would need an even bigger chute. One that was 400 feet in diameter. But, in reality, Curiosity’s parachute was nowhere near that size. It was only 70 feet in diameter.

Why? Because the bigger the chute gets, the greater the chance it will rip. In fact, the largest parachute ever built and tested was just 150 feet wide. So, in the end, it’s physically impossible to build a parachute big enough. Which makes landing on Mars risky at best. So, how do space agencies do it? Very carefully.

First, the spacecraft deploys its giant parachute to slow down as much as possible  — usually to around 200 mph. Then, it fires retrorockets to take it the rest of the way.

And that might not sound so hard but if the parachute doesn’t deploy at the right time, or the rockets don’t fire at the right height, it’s all over. To date, only three space agencies have ever tried to land on Mars: NASA, the European Space Agency, and the former Soviet Union. None have a perfect record.

So, if landing on Mars is so hard, why do we keep doing it in the first place? Besides the Moon, Mars has more artificial instruments on and around it than anywhere else in the solar system. And you could say that’s because Mars is close by. Or that it might be the best spot to search for signs of alien life. Or could it be that with each successful new landing we come one step closer to the grandest ambition of all: To become the first species ever to inhabit a world beyond our own.

Why Mars Is The Hardest Planet To Land On

Saturn is losing its rings faster than previously thought. Scientists estimate the rings will be gone in 100 million years.

Saturn Is Officially Losing Its Rings

Snapchat has lost millions of users and is now significantly less popular. After a failed redesign and negative feedback from celebrities like Kylie Jenner, Snapchat has struggled to win users back while Instagram and Facebook steal their most popular features.

Following is a transcript of the video:

Shona Ghosh: They made a few kind of missteps around things like the redesign not focusing on Android as much as they should have done, so there were definitely mistakes made by Snapchat. But, for sure, you could look at the story of Snapchat and say, essentially, Facebook may have ruined this quite-promising company.

So Snapchat is in a little bit of trouble. Its stock price has fallen substantially over the last couple of months. Snap has said it's losing daily active users, and the worrying indication is that probably people aren't using Snapchat as regularly as they used to. But, you know, it's really difficult in the current environment to compete against Facebook 'cause it's got loads of money. It's got the biggest online ad business alongside Google, and if you're trying to sort of compete with the two of them, it's really hard unless you have a lot of money and you have a lot of luck going your way in terms of attracting users.

The other disaster that Snapchat had was its redesign. What made Snapchat really popular with young people was that it was kind of difficult to understand. You had to really understand how apps work in a way that sort of young people really do and older people find a bit tougher. Unfortunately, it was a complete disaster. A lot of the loyal, younger users and celebrity users of the app, people like Rihanna quit. And Kylie Jenner, you know, said on Twitter, actually, I'm not that keen on opening the Snapchat app anymore, and it's probably not really managed to recover from that disaster.

So, Snapchat has probably not done itself any favors by doing things like having a really terrible Android app. The app works much better on iPhone, and when Android is the most popular mobile ecosystem in the world, that's a bit of a problem if your app for that ecosystem isn't very good.

Then there are also lots of questions about its CEO and co-founder, Evan Spiegel, who's very young. Spiegel is still in his 20s which is, you know, insane to be leading a multi-billion dollar company as he is, but to do it successfully, you need to be a really good manager, and there are some signs that maybe Spiegel's a little bit secretive. He doesn't communicate that well with his team, so there's been a combination of factors that has probably made life quite difficult for Snapchat right now.

Facebook tried to buy Snapchat at least once, possibly twice, over the last few years, and so to kind of make up for that rejection, Facebook simply copied a lot of Snapchat's coolest features and put them into Instagram, and actually, Instagram stories is more popular than Snapchat stories. It's going to be a really tough challenge to go up against things like TikTok, the really popular music app. Snap's sort of reputation has always been about being cool rather than useful, and so something like WhatsApp, which is a sort of Snapchat competitor in that it's a messaging platform. It's always gonna be popular because it's really useful. Unless Snpachat can sort of really show users that it's useful as well as cool, it's going to be really tough to get people back on the app if they've left.

You would be amazed at how long companies can limp along, even if they appear to be losing users. I think a really good example is Twitter, which everyone has been writing off for several years, but actually sometimes Twitter turns a profit. It's not doing brilliantly in terms of retaining users, but it's certainly not going down the toilet. I feel like Snapchat could perhaps be similar, and people do see it as an alternative to Facebook, so they may want to keep that alternative around. Snapchat could actually last for a very long time, even if it doesn't change very much, as long as it does keep rolling out some updates. It's possible it could go on for many years into the future.

What's Going On With Snapchat | Untangled

Why do all smartphones look the same? The original iPhone design focused on the touchscreen, instead of a keyboard. In 2007 Apple created a design trend that has lasted more than a decade. Phones now have bigger screens and fewer buttons, putting the focus on the apps. And companies have continued to follow Apple's design after the iPhone X, now many Android phones also have the iPhone's recognizable notch.
