Read More: How Much Memory Do You Need on Your Phone?

Facebook

Yes, the social media giant takes up a lot of space on your phone, topping the list of some rankings as the biggest space suck of all. At a minimum, Facebook takes up 200MB of storage. Facebook Messenger is in its own category; the messenger, which isn’t a part of the Facebook app, also takes up a significant number of MBs.

Spotify

Perhaps it isn’t surprising that a music streaming service top the lists of the biggest storage hogs on Android. With such an extensive catalog, Spotify’s cache can take up more and more space on your device, with some users reporting that it takes up nearly 2GB of internal memory on their Androids.

Instagram

Like Spotify, the photo-sharing social media channel caches files, which is one of the reasons that the app might take up more room on your phone. Even though the more you use Instagram, the more photos will be stored, you’re in luck: the app’s cache resets weekly so it won’t become completely unmanageable.

Snapchat

Snapchat isn’t such a big offender when you first download it, clocking in at around 3MB to download. However, like the other apps, it starts growing and growing the more you use the app. As your cache accumulates, you might find that Snapchat uses 10MB or more of your storage space.

If any of your favorite apps are on this list, you might be better off getting rid of them using App Manager. A fast phone with sufficient storage space is often worth more than even the most popular app.

Therefore, it’s very concerning if these satellites can become hacked — false information could be transmitted, entire satellite systems could be shut down, or valuable data of all types could be stolen. That means that satellite hacking, in the future, could potentially affect billions of people, depending on how large a cyberattack is. It certainly extends far beyond sensitive information on space explorations.

NASA’s Concern with Space Hacking

That’s why NASA has grown increasingly concerned with space hacking — specifically satellite hacking. NASA gathers a lot of valuable data from space explorations — data which could easily be stolen, due to NASA’s aging computer system. Although efforts are made to secure this data, it is still not as secure as it could be.

As mentioned, much more than data from space explorations is at stake. In NASA’s case, they must maintain the security of their email system, scientific data, and their control systems at various labs and research centers. There is also a big concern for data transmissions being intercepted, whether by a certain company or else by a country. Either way, space hacking would be an act of cyber warfare — and it could come with much more severe consequences than stolen data.

Making Efforts to Improve Cybersecurity

In an effort to decrease their risk of hacking, NASA is working on improving its cybersecurity efforts over the next year or two. This is a crucial move, especially since NASA reported nearly 1,500 cases of cyber attacks in 2016. They are currently working on analyzing their systems to catch any vulnerabilities and quickly patch any issues.

Still, it’s not enough — all organizations and companies dedicated to launching satellites and exploring space should be more concerned with the security of their equipment than how quickly they can launch it. Plus, spending more time on testing equipment should help to reduce or eliminate costly space failures.

One way to improve cybersecurity in space is to use a quantum communications satellite. China launched this type of satellite last year. According to cybersecurity experts, this type of satellite is virtually hack-proof.

Get Rid of Emails With Attachments

Emails with big attachments can take up the most space in your inbox. So, if you’re only going to delete certain emails, these are the ones with which you should start. To find emails with attachments, search for “has:attachment” in the Gmail search filter. If you’re hesitant about how to begin getting rid of your emails, clearing out these big attachments is a good way to start.

Clear Out Your Largest Emails

Getting rid of the emails that are taking up the most space is the best thing to do, but it isn’t always simple. If you use an IMAP client such as Mozilla Thunderbird, you can start sorting emails by size and attachments. By using the IMAP client and sorting your email sizes, you can then delete the emails that are taking up most of your phone’s memory.

Find Your Biggest Emails Instead

If you don’t want to download an IMAP client, you can also use a third-party service called Find Big Mail to scan your messages. This web-based service takes temporary access to your email, scans through your emails, and creates labels in your account so you can browse for large messages without engaging the Find Big Mail site.

Stop Receiving Bulk Mail

The easiest way to keep your inbox close to empty is to stop getting as many emails. You’re probably subscribed to plenty of newsletters and mailing lists that you don’t read, so why not unsubscribe? Use an app like Unroll.Me or do it manually. It only takes a few minutes, and it will keep your inbox free of clutter. Or, you choose to receive fewer emails per week from many of these business if you still enjoy receiving notifications and updates.

DFNDR’s Duplicate Photos function is most salient to the issue at hand. This feature will identify any repeated photos in your image gallery, and give you the option to select and delete these copies with ease. This way, you’ll have more space for worthwhile photos in no time. If you have a lot of photos on your device, then this is a necessary feature to take advantage of because you’ll spend a lot less time identifying and removing duplicate photos. Click here to locate and delete duplicate photos in order to free up space on your device:

You can free up a lot of space by deselecting the HDR mode on your Android’s camera. Open up the camera app and click the cogwheel in the corner to take you to settings. You should see a grid consisting of different camera features. Find the “HDR (rich tone)” and make sure it’s “off.”

However, turning off your HDR mode doesn’t delete the previous photos taken by your HDR camera, which are likely hogging memory. That’s why, in addition to turning off this mode, you should use the Duplicate Photos feature to remove unnecessary photos and free up space on your device.

If you still want to take HDR photos, then make sure to backup all of your photos to your computer or to cloud storage more frequently. After the backup is complete, remove all of the HDR photos from your phone. That way, you can still use your phone to take HDR photos, but still have storage space on your phone for new apps, photos, videos, and more.

Elon Musk plans for Mars to be inhabited by around 1 million people. He justifies this number by explaining that Mars would be self-sustainable with this amount of people even if SpaceX runs out of resources to transport more people to Mars. He claims that the first humans will set foot on Mars in January 2025, and that the mission will be completed by 2074, when he estimates the population will surpass 1 million.

Although Elon Musk’s plan seems as if it is not too far off from now, the plan is still very much in its early developmental stages. While SpaceX has successfully launched and landed many rockets, a great deal of testing still needs to be done in the next nine years. The first step in Musk’s plan is to land the Dragon spacecraft in July 2018, which would carry the first shipment of cargo to Mars. If this mission is successful, SpaceX will continue to transport more cargo to Mars, leading up to the Maiden BFS voyage in December 2022 — this is the mission in which SpaceX plans to send the last shipment of cargo.

By 2025, Elon Musk may have figured out how to prevent human extinction in the event of any major disasters. With global warming on the rise and more scientific research revealing its danger, having a second planet for humans on Earth to turn to may be one of the most helpful solutions that has been proposed to date.

The SpaceX Explosion
At the beginning of September, SpaceX launched Falcon 9 as part of a trial run, and the rocket exploded. Until recently, the cause of the explosion was unknown. They now believe it was due to a helium system breach, but they are still looking into the matter. Luckily, no lives were lost due to the explosion. But the Falcon 9 incident is a major setback for SpaceX and even space travel. This isn’t SpaceX’s first Falcon 9 explosion, either; they had a rocket explode in 2015. These major SpaceX failures have not only cost the company an exorbitant amount of money, but time as well.

Other Major Spaceflight Disasters
The Challenger space shuttle first launched in 1983, and completed many missions before the 1986 accident, where seven people lost their lives. The space shuttle didn’t technically explode: an issue with the fuel tank led to its failure, which caused the tank to release fuel that created a trailing fireball. One issue with this disaster is that it might have been avoidable if the shuttle had been launched during appropriate weather conditions.

The Columbia space shuttle had completed dozens of successful missions before its failure in 2003. As it was returning from a mission, the shuttle disintegrated, killing all seven people on board. The accident was caused by broken insulation during takeoff, which led to the damage of the shuttle. Oddly enough, some worms that were part of an experiment survived.

1. Android’s Built-in Storage Tool

 The first step to managing space on your device is to figure out exactly what is using data and how much it is using. Android comes equipped with a tool that shows you exactly how much room each app is taking up. To get there, open the Settings screen and go to the Storage section. There, you will find a list of apps, photos, audio files, downloads, etc and how much of the available space they are using. With this information, you can delete or move items that are taking up the most room.

2. Add an SD Card

Another way to free up space is to literally move information to a new location like an SD card. Many Android devices still come with an SD card slot even though they are now unnecessary to the functioning of the phone. If they do, you can insert an SD card, connect the device to your computer, and upload files to it. You will have access to this information whenever you insert the SD card into your phone or computer so you can access it easily.

3. Upload Photos

Unfortunately for people who like to look back at their photos to reminisce, pictures take up more than their fair share of space on a device. A more viable option to keep space free is to upload the photos to an online account using an app like Dropbox or Flickr. These apps let you access your photo gallery via an online account and upload photos. After uploading, you can delete them from your phone, freeing up space while still having access to your photos stored on online servers.

4. PSafe Total Android

 PSafe offers a program called “PSafe Total Android” that works to make your phone operate more quickly and efficiently by freeing up space and adding extra security, among other things. One of the features deletes audio files stored on apps like Whatsapp to get more space for other media files. By downloading the PSafe Total program, PSafe manages apps running in the background or taking up extra space to free up storage space on your phone and improve how fast it operates.

5. Check Out Your Apps

 Another big space filler are your different apps. To check how much storage each app is using, click on the Apps tab in the Storage section to see each app and how much data it takes up. You can then tap on each app to clear its cache and make sure that it is not using extra data. Then, if necessary, you can clear its data entirely to reset it back to its factory settings and ensure it isn’t storing any extra information.
