Search and rescue efforts continue as sunlight shows the extensive damage left after Jonesboro, Arkansas, took a direct hit from a tornado on Saturday, causing major damage.
Didymos, a 2,650-foot-wide asteroid, has an atypical cosmic companion— a 535 foot-wide satellite named Didymoon (10). These new two celestial bodies are not making a dangerous rendezvous with Earth, but they do provide an interesting opportunity for an apocalyptic dress rehearsal. NASA and ESA’s Double Asteroid Redirection Test (DART) will head to Didymos, to knock Didymoon off course. Along with its six picture-snapping Italian Space Agency cubesats, the mission will also send a follow-up ESA spacecraft named Hera to definitively answer if we can manipulate the trajectory of Earth-bound asteroids.

Social distancing is here to stay for much more than a few weeks. It will upend our way of life, in some ways forever.
Clinical and design considerations will be published online; goal is to support rapid scale-up of device production to alleviate hospital shortages.
Planetary defense researchers at Lawrence Livermore National Laboratory (LLNL) continue to validate their ability to accurately simulate how they might deflect an Earth-bound asteroid in a study that will be published in the April issue of the American Geophysical Union journal Earth and Space Science.
The study, led by LLNL physicist Tané Remington, also identified sensitivities in the code parameters that can help researchers working to design a modeling plan for the Double Asteroid Redirection Test (DART) mission in 2021, which will be the first-ever kinetic impact deflection demonstration on a near-Earth asteroid.
Asteroids have the potential to impact Earth and cause damage at the local to global scale. Humankind is capable of deflecting or disrupting a potentially hazardous object. However, due to the limited ability to perform experiments directly on asteroids, understanding how multiple variables might affect a kinetic deflection attempt relies upon large-scale hydrodynamic simulations thoroughly vetted against relevant laboratory‐scale experiments.
It is vital that would-be bombmakers be disabused of any notion that they could evade tough international sanctions. We need a country-neutral, reasonably predictable, more-or-less automatic sanction regime that puts all countries on notice, even friends of the powerful.

Just as we’ve had to discard business-as-usual thinking to deal with the current worldwide health emergency; it’s time to get serious about the spread of nuclear weapons. It doesn’t have the immediacy of the coronavirus, but it will last a lot longer and is no less threatening. In particular, we need to fortify the Nuclear Nonproliferation Treaty (NPT), which is fifty years old this year and badly needs fixing. The April 2020 Review Conference will likely be postponed, which provides time to develop something more than the usual charade of incremental proposals that nibble at the problem.
Analyzing the specific data of each country separately suggests that there is a light at the end of the tunnel – and that the tunnel is not that long.
