DART Mission – Double Asteroid Redirection Test

 


What is DART Mission all about ?


  • Target the binary asteroid Didymos system
  • Impact Didymos-B and change its orbital period
  • Measure the period change from Earth


The Double Asteroid Redirection Test (DART) mission is directed by NASA. DART is a planetary defense-driven test of technologies for preventing an impact of Earth by a hazardous asteroid.

It has been noticed that unprecedented asteroids occasionally drift towards earth but are often destroyed by earth’s atmosphere. But, sometimes they do make an impact which can be equally devastating to that of an atomic bomb. To prevent such asteroids from hitting the earth’s surface Nasa is carrying out a round of tests with their DART Mission Team.

The near-Earth asteroid Didymos is the target for the DART demonstration. The DART spacecraft will achieve the kinetic impact deflection by deliberately crashing itself into the moonlet at a speed of approximately 6.6 km/s, with the aid of an onboard camera and sophisticated autonomous navigation software.

The DART spacecraft launch window begins in late July 2021. DART will launch aboard a SpaceX Falcon 9 rocket from Vandenberg Air Force Base, California.

Is React Native Garbage ?

Well we shall look into two different scenarios inorder to understand this fully. Scenario 1. Company like Google or Apple who wants to release an app and wants real crazy fast app load, wants better control over hardware and does not much care about the cost of hiring teams of native developers for different platforms. This is the case when one should opt for Native code bases like Java or Swift.  Now lets look at our next Scenario. Scenario 2. A startup wants to grow crazy fast. It has cost constraint but wants to reach the consumer base of both web, ios and android. In such a scenario, the startup settles down with a framework like React Native and does not bother if the app loads up a little slow, and serves its purpose of getting to the larger audience faster with a bunch of Javascript Developers. So, nothing is garbage. Its just two different scenarios and different priorities based on Business demand.
