Researchers Propose Using Lasers to Zap Potentially Dangerous Space Debris

Space Junk

Pollution isn’t just a problem here on Earth. It’s also an issue in space where a growing collection of space debris is orbiting our planet. From used rockets to fragments of obsolete satellites, millions of pieces of this space junk are not only cluttering up space, but also threatening our off-world operations.

Space junk can cause serious problems if a piece collides with active satellites or the International Space Station (ISS). To combat this growing issue, Chinese researchers are exploring the possibility of blasting space debris using orbital laser stations. Their research has been published in Optik – International Journal for Light and Electron Optics.

This is not the first initiative focused on the elimination of space junk. Researchers have proposed dragging it out of orbit, trapping it in an orbital net, and even slowing it down so it would burn up in Earth’s atmosphere. However, the Chinese researchers’ laser-oriented project could be the most effective yet.

For their study, the scientists successfully simulated an orbital laser station that would target and zap pieces of space debris under 4 inches long with 20 bursts of light per second for 2 minutes. This zapping is designed to either force the junk to burn up in the atmosphere or push it out of the way, preventing collision.

The team concluded that it would be possible to launch these laser stations and that they would be effective in clearing out space junk and preventing future collisions.

Overcoming Obstacles

These orbital laser stations could solve a major problem for the space industry. In 2015, the ISS crew had to evacuate their living quarters after an old satellite threatened to collide with the station. Had it actually collided, it could have damaged billions of dollars worth of equipment.

However, this laser-blasting plan isn’t without issues.

Firstly, it is only equipped to destroy very small pieces of space debris. It is unclear whether it could push much larger pieces of space junk out of harm’s way. The logistics of creating the laser stations would be complicated, too. Who would build them? How many would they build? Additionally, while the orbital laser stations are designed specifically for demolishing space junk, is it possible that they could be used as weapons?

Government agencies would need to work out answers to these questions and others before this successfully simulated technology could be utilized in the fight against space junk.

If they could find a way to ensure the orbital laser stations were used safely and as intended, though, the stations could make a major dent in the space junk problem, which is expected to get worse in the coming years, with thousands of new satellites on track to join those already in low-Earth orbit by 2025.

So far, all of the proposed solutions to the growing space junk problem have significant downsides, so we’ll need better solutions if we have any hope of preventing our active technologies from becoming dangerous space junk in the future.

How to Connect to a Personal Wi-Fi Hotspot Using Bluetooth

In a previous daily tip we discussed how to set up a Personal Hotspot using your iPhone, and how to connect your devices to it using Wi-Fi. But what to do if Wi-Fi is unavailable or unreliable? You’re not out of options; it’s time to connect to your Personal Hotspot using Bluetooth. While your Bluetooth connection will be slower than Wi-Fi, it does have its charms. Bluetooth uses far less power than a Wi-Fi connection, is more secure, and features automatic pairing—as opposed to Wi-Fi, which has a lag while your laptop, iPad or iPod connects, and may require you to rejoin the network every time your device goes to sleep. So without further ado, let’s learn how to connect to a Personal Hotspot using Bluetooth!

Solid Advice For Successfully Using Your IPad.

iPads let you do many things at once. However, it’s important that time is spent on learning all there is know about the iPad. Use the information in the following article to prepare yourself for the optimal use of this incredible machine.

If your friends own iPads too, you can share your entire music and video library with them. Open your ITunes app and activate the home sharing function. You also need to enter your Apple ID in the music and video menu of your iPad. To access a shared library, open a music or video app and select more. You will then have access to a list of shared libraries.

If you do not yet own an iPad, consider buying a refurbished iPad from Apple’s online store. Buying a refurbished iPad can save you a lot of money. What’s more, most of the refurbished iPads that Apple sell come with generous warranties and it can be difficult to tell that they are not brand new.

You don’t need to press the small camera icon that’s found near the bottom left of the screen to see videos or pictures you just took. Simple swipe right with a single finger and you will see your video or photo. Previous photos of yours will show to the left.

There is a place where you can change the settings to look at more lines of preview text in your email Go to your settings, tap on mail and change the preview settings. Adjust this to show 5 lines. This will give you a larger range to view when you are skimming.

Many iPad games and apps have a feature that notifies you whenever some action is performed. For example, you may receive a notification from Words With Friends that it is your turn to play, or you might have a Twitter alert that tells you someone has re-tweet something. Disable these notifications unless they are absolutely necessary. These frequent updates can shorten the life of your iPad’s battery.

For the devoted iPad user who spends a lot of time traveling, it is essential to carry an extra battery that has been charged. It is very inconvenient to run out of juice while on a plane or train, with no hope of plugging in a charger until the destination has been reached.

Your iPad will now support a VPN connection. You just need to configure it first. Start by going to your Settings menu. Look under General to find Network. Choose the VPN and switch that slider to On. You can then add the VPN configuration using your account details and server.

Are you constantly annoyed by the AutoCorrect on your iPad? Try this trick in the future. After you finish typing your word, tap on it in the suggestion’s area. That will ensure that you get what you typed instead of the AutoCorrect suggested word that automatically gets inserted when you hit a space.

Use the following trick to quickly mute your iPad. Just hold down the volume down button for a couple seconds. This is a lot easier than constantly adjusting the volume controls. When you want to hear your device at a normal level again, just hold the volume down for the same amount of time.

Get a USB keyboard. When you get a keyboard, you expand your abilities with the iPad. Keyboards are often more comfortable for posting on Facebook, forums and doing other online writing. That allows you to be more efficient. Some keyboards double as a case, so check out the options available.

If you are preparing to sync your iPad with your computer for the first time, choose wisely. If you indicate that you want to sync ALL of your pictures, videos and music, be prepared. Depending on how much you have, it could take a long time to fully transfer everything over. Instead, use your discretion and only sync those items which you know you will need on the iPad.

It is very easy for you to email other people photos while using your iPad. All you have to do is locate the photo you want to send and press the button located in the right-hand corner. There is an option there that will allow you to send the photo to anyone you want.

If you plan to take your iPad into the kitchen, you absolutely must have a screen protector, stylus and standing case. You will accidentally drop goo all over your iPad, and the protector and case will ensure it says off the iPad itself. The stylus keeps sticky fingers off the screen, too.

Accessing the second scree of your keyboard every time you need a full stop can quickly become annoying. You can save a lot of time when you type by pressing the space bar twice when you need to insert a full stop in your text or by using a wireless keyboard.

You can share music between your computer and iPad through Home Sharing. Go to iTunes on your computer and set Home Sharing to on and then go to Settings on the iPad and enter your Apple ID in the Music/Video area. Open the music or video app on your iPad and you’ll be good to go.

If you have a child or a minor using your iPad, you may be interested in turning off mature content. To do this, tap on general, restrictions, and then enable restrictions. This feature will block TV shows, movies, and apps that are “mature audience” rated. Also, podcasts that have an “explicit” tag will be blocked.

Is the battery percentage notification making you crazy? There’s a solution! Go to Settings and then General, click on Usage and set Battery Percentage to Off. This will mean you have to watch your battery charge on your own, but it could save you a ton of annoying notifications down the road.
