Space Junk is getting worser and worser!

 

There are about 5 lakh debris or space junk orbiting our planet at a speed of 28000 km/h! This issue is a rising problem for space stations and institutions. Their velocity is very fast, such that it can go through and damage satellites and spacecraft.



WHAT ARE THESE SPACE JUNK

These space junk consists mostly of synthetic materials but also some debris of meteoroids. The artificial junks are the unused or dead spacecraft, launch vehicle stages and mission-related debris.

There is about 2 lakh debris that outsizes a softball, capable of damaging anything that comes in their way.


EVENTS

  • 1996: a French satellite was damaged due to the explosion of Fench rocket which occurred a decade earlier.
  • February 10, 2009: a disused Russian spacecraft collided and ruined a functioning a US Iridium telescope. It added more than 2000 debris to the orbit!
  • 2007: China used missiles to destroy an old weather satellite, adding more than 3000 debris.


HOW TO AVOID HITTING BY A DEBRIS

Nasa is constructing spacecraft which are debris-proof and travelled in a different way to avoid debris. NASA processed all NASA manoeuvrable satellites within low Earth orbit and 200 kilometres of geosynchronous orbit. You can know more about it in NASA's post.

Why are there different types of Mozilla Firefox?

  Firefox is a fast and famous browser, developed by a non-profit. Firefox's speed and privacy were the key points that brought them up. By hearing all this, at last, you go to Mozilla Firefox Website to download it. But there are different types! Which one should you choose and which one you should download? STABLE EDITION It is the most used and stable Firefox Browser. It is the one you have seen in your computer lab. Firefox updates it every six weeks, checks and revises and, thus bug-free. BETA EDITION   It is one step ahead from the stable version. Beta versions have the next update or release of the stable version but sooner. Beta also has some minor security things for good. For instance, a developer can run an unpublished add-on in the beta version, but not in the stable version since the stable version does only allow authorised add-on. Beta can be good for those who are curious browser to see the next updates. For the developers, we have the next one! DEV EDITI...

RTX 3000 Series - The Game Changer

NVidia Geforce RTX 3080 The new RTX 3000 series announced yesterday live on YouTube. The CEO of NVidia, Jensen Huang, announced the features, release date and many more. Computer graphics have improved a lot since the start of computing. RTX 3000 series would be a game-changer in the GPU industries. Jensen Huang, the CEO of Nvidia announced 3 RTX 3000 Series Graphics Cards - RTX 3070, RTX 3080, RTX 3090. This new-gen graphics card design with Ampere Architecture. RTX 2000 series uses Turing architecture and GTX 1000 series use Pascal architecture. Ampere Architecture is said to have better performances and features (1.9 times) than previous GPUs. It also has 28 billion transistors, having the world’s fastest Graphics speed (760GB/s) with 3rd gen Tensor cores. This time Nvidia has joined with Samsung to produce the 7nm processors.  The game Marbles with RTX enabled “ Ampere is the biggest generation leap we had ”  The pricing of the RTX 3000 series is low...

Apple Silicon is here!!

 In the latest launch event held by Apple on 11th November 2020, they have announced the new Silicon processor for Mac line-ups such as Macbook and iMac. Silicon processors have been developed for decades and been used for their Tablets, Watches, and Smartphones. Earlier this year, they have announced to cut ties with Intel - which was the processor they have been using for its Pc line-ups previously and make their own processors for the average workload done by an average OSX user. Silicon chips usually co consume less power and still outputs incredible performances.  The Silicon chips which will be specifically used in Macs are called the "M1". Usually, every computer has its RAMs, GPUs, I/O, separately. But M1 unifies all those components into one set. The Unified memory architecture provides High Bandwidth of data transfer as fast as possible and access to the entire SoC. This is also the first CPU to use 5nm transistors (While AMD  uses 7nm). "M1" has 16 bill...
