Mission DART. To save the earth from hazardous asteroids threat.

Do you remember the day 29th April,2020. An hazardous asteroid named 1998 OR2 completed it's closest countdown with our planet, and Luckily it didn't collide with the earth. 

If it made collision that time, maybe I'll not able to write this blog for you, and you will not there where you are right now. Meanwhile there was a chance of extinction of Civilization.So we are safe from this asteroid right now.

Yes but not safe from other near earth asteroids. Scientists estimated that, there is 25000 near earth asteroids orbiting in the solar system. So there's a lot of chances of Asteroid threats. 

Is there anything to protect our planet from asteroid's Collisions?
No :( But Surprisingly, NASA is working with a project named DART ( Dual Asteroid Redirection Test). It's a planetary defense-driven test of super technologies for preventing hazardous impacts due to asteroids collisions. DART's spacecraft is a space probe that will crash or collide with an asteroid moon for changing it's trajectory and planetary defense.


The project is now in Phase C according to NASA. The targetted asteroid is Binary near-earth asteroid 65803 Didymos B. It's around 780 meter width. And it's secondary body or it's moon named Moonlet which is around 160 meter width which is more typically at the size of asteroid that can create a significant threat to The Earth.

DART spacecraft will crash the Moonlet at a speed of approximately 6.6 km/s with the help of an onboard camera named DARCO and a sophisticated autonomous navigation software.
This collision will change the speed,motion of the Moonlet in it's orbit around the main body Didymos. DART spacecraft will use  Roll Out Solar Arrays (ROSA) to provide the solar energy headed for DART'S electric propulsion system.

ROSA arrays was tested in ISS(International Space Station) in June,2017 as a part of Expedition 52.



The DART spacecraft launch window begins in late July,2021. The expected time is 22 July,2021. It will use Falcon 9 rocket of SpaceX from Vandenberg Air force Base, California. After separation or final staging from the launch vehicle and over a year of cruise, the spacecraft will crash Didymos B moon Moonlet in late September 2022, when the Didymos system is within 11 million km of Earth.

What are the chances of Victory?

Welcome to this blog. Just one thing dear, you've to scroll until you are done. So don't Fly away. This is Umar Bin Nazim addressing you in the Internet world as DrKnight .

But an accident just changed my whole life's trajectory and that's why I couldn't. So let me introduce myself with a short description. I was born in Sylhet region, Bangladesh. The time was 2002. My dad was a businessman, and before business he was an Incharge later DGM in a popular Food Producing Company in Bsic, Moulvibazar.Just a little bit about my dad is that, I often bless me as the luckiest person because I found an ideal,talented,deepthinker father. But he's not more in the world since 2018 just for a Brain stroke for his hypertension. So I was a student of English and Bangla medium in my school life. I spent

Do You Want To Walk In The VIRTUAL REALITY WORLD?

How's everything buddy? Again welcome to DrKnights Blog. One thing,please scroll until you read the blog completely. Virtual Reality. What is virtual reality? It is a simulated experience made by Computer. The internal virtual world can be like real world or completely different.  We all know about GTA games where we can play as a character. We can move the character as we want.What happen if we become the character and get into our pc and play in the Gta world? Yes, it's now 100% possible by Virtual Reality  We can make a 3D world in Computer and trouble where we want via VR. Isn't it amazing. So here's the simple concept about virtual reality. Now question arose,What you need for Virtual Reality? Well, here's a simple guide for you. You need( You Can skip it ), HMD like, HTC vive or Oculus Rift. Intel core i5-4590. NVIDIA GTX 970 or AMD R9 290. 8GB RAM. HDMI 1.3 and 3x USB 3.0 plus. Windows 7 64 bit or greater. So, wear and go into the virtual reality world and do
