Ten Years After Katrina

As we remember the devastation that Hurricane Katrina caused ten years ago, we also look to the improvements made in the past decade in storm prediction and forecasting.

Hurricane Katrina impacted many people, businesses and communities; and even two NASA facilities were hit by the storm. Marshall Space Flight Center and Michoud Assembly Facility were both hit by the harsh storm (seen below).

During Hurricane Katrina in 2005, our satellites were hard at work monitoring and watching the storm from above. Thanks to the higher resolution models we have today, simulations can recreate historical storms, like the below of Hurricane Katrina. Scientists can then study these and learn about past events.

Surprisingly, the United States hasn’t experienced the landfall of a Category 3 hurricane or lager since 2005. This is the longest period of time that has passed without a major hurricane making landfall in the U.S. since reliable records began in 1850.

Although we don’t know when a severe storm will form, we do know that advancements in technology can help us better prepare and predict its path. So, on this ten year mark of this devastating storm, we look back to remember what we saw: https://www.flickr.com/photos/gsfc/sets/72157656646633089

Hello! I'm a person, and I find physics (specifically astrophysics) to be incredibly interesting, and I'd like to know more about it. Have any idea on what I should read/watch to get more educated on the subject? I don't know where to start ^^".

Well I get a lot of my updates in the science world from here, http://www.sciencedaily.com/news/space_time/astrophysics/ just look under the astrophysics section then when you get to understand some of the key concepts the look up papers on science direct and google scholar for the best free papers :)

First time shooting the Perseid meteor shower. Definitely doing this again and I’ll try to get the Geminids in December as well. Finally edited and put these pictures together. This one turned out pretty good I think, I also have some more on my flickr account with better quality. There’s about 40 meteors here, captured from both nights and combined into one. Was up on Mt. Lemmon for both nights and started shooting from midnight to about 4am.

Space Launch System

Our Space Launch System (SLS) is an advanced launch vehicle for exploration beyond Earth’s orbit into deep space. SLS, the world’s most powerful rocket, will launch astronauts in our Orion spacecraft on missions to an asteroid and eventually to Mars!

A launch system required to carry humans faster and farther than ever before will need a powerful engine, aka the RS-25 engine. This engine makes a modern race car or jet engine look like a wind-up toy. With the ability to produce 512,000 pounds of trust, the RS-25 engine will produce 10% more thrust than the Saturn V rockets that launched astronauts on journeys to the moon!

Another consideration for using these engines for future spaceflight was that 16 of them already existed from the shuttle program. Using a high-performance engine that already existed gave us a considerable boost in developing its next rocket for space exploration.

Once ready, four RS-25 engines will power the core stage of our SLS into deep space and Mars.
