US to test nuclear engine for future Mars missions

NASA and the US Defense Advanced Research Projects Agency (DARPA) have announced a collaboration to demonstrate a nuclear thermal rocket engine in space, the key steps for sending the first crewed missions to Mars.

Nuclear threat

 For over a decade starting 2006, multiple United Nations (UN) resolutions okaying the implementation of ever harsher sanctions seeking to dissuade North Korea have been the norm


In 1994, Ukraine returned to Russia almost 2,000 nuclear weapons that it had inherited receiving in return a guarantee, in the form of the Budapest Memorandum (also signed by America and the United Kingdom), that Ukraine would not be attacked. Today, Kiev is probably ruing the day it agreed to do so.

Pyongyang’s playbook

Pyongyang appears to be inching closer to its earlier threat to consider suspending a self-imposed moratorium on nuclear and long-range missile tests amidst an impasse in its nuclear negotiations with America. The latest launch suggests that Kim’s moratorium is already broken. In recent months, North Korea has ramped up its testing activity.
