NASA Launches a Rocket from an Airplane to deploy CYGNSS

Standard

On December 15, 2016 NASA successfully launched 8 small satellites by releasing a rocket from an airplane. The 8 satellites form the Cyclone Global Navigation Satellite System (CYGNSS) for tracking and studying the inside of tropical storms and hurricanes.
This step of releasing a rocket from an airplane is part of cutting costs.

Amazing NASA simulation of Solar Wind Striping the Martian Atmosphere

Video

The following video by NASA’s Scientific Visualization Center simulates the Martian atmosphere being striped by incoming solar wind.

More videos and images can be found here.

Mars is a cold and barren desert today, but scientists think that in the ancient past it was warm and wet. The loss of the early Martian atmosphere may have led to this dramatic change, and one of the prime suspects is the solar wind. Unlike Earth, Mars lacks a global magnetic field to deflect the stream of charged particles continuously blowing off the Sun. Instead, the solar wind crashes into the Mars upper atmosphere and can accelerate ions into space. Now, for the first time, NASA’s MAVEN spacecraft has observed this process in action – by measuring the speed and direction of ions escaping from Mars. This data visualization compares simulations of the solar wind and Mars atmospheric escape with new measurements taken by MAVEN.

In a previous post I shared a video on mixing and unmixing of fluids. This time I share with you an image I took of my coffee. With some milk fluid dynamics created amazing vortices. Following it is an animation of the time evolution of the vortices.

Breaking News: SpaceX Falcon 9 rocket explodes 2 minutes after launch

Standard

The Falcon 9 rocket launched earlier today to supply the International Space Station with food and supplied.

At launch a propulsion anamoly was detected and the rocket, at highest pressure, exploded 2 minutes after launch. Footage of the incident is below:
