Today marks the 40th anniversary for the launch of the Viking 1 lander/orbiter to Mars in 1975, which set the stage - err, launch pads - for subsequent flyby, orbiter, lander, and rover missions. 

Although some of these missions are marked as “failed” attempts, an engineer or flight controller would dismiss this classification, as data from every mission parleyed information for the next. Failures? No. More like “growing pains” in our spacefaring adolescence. 

The year 2015 marks another noteworthy anniversary to which the Viking program laid the foundation for our curiosity and present trajectory for NASA’s #JourneyToMars. 

This wonderfully produced video from NASA’s Jet Propulsion Laboratory (JPL) conveys the breadth of vision and the excitement from, among every aspect of each robotic mission, successfully received data! 

Enjoy, and continue the journey with us as we work to preserve the legacy of the Viking program with The Viking Mars Missions Education and Preservation Project, the #FirstOnMars! 

The first two images are tesseracts and the second two are 4D spheres. 1 Dimension: in a universe with one dimension, particles can only move in a line so from left to right not up and down. _____________________________

2 Dimensions: this is made up of an infinite amount of 1D universe and particles would be able to to move in two dimensions, up down left and right. Now if there was an organism living in a 2 dimensional it would see things in 1 dimension just like we see things in 2 dimensions and our brain is what is able to interpret depth by using two eyes and our brain. When we hold our finger in front of our face and move it, we can see that it appears to have moved relative to the background. Our brains see this difference and this allows us to estimate how far away they are. In a 2D universe there would be no background as such to see the “finger” moving against so it would be seen in 1D although it’s impossible to visualise anything in 1 dimension.

3 Dimensions: we live in 3 spatial dimensions in our universe which is made up of an infinite amount of 2D universes. We see things in 2 dimensions. A common misconception is that time is the 4th dimension but it doesn’t really make sense because it is present in every spatial dimension.

4 Dimensions: this is almost impossible to try and visualise. There are some people who claim they can think in 4 and even more dimensions. Now, a 4th dimensional organism would see things in 3 dimensions. If they came to our universe then they would be seeing absolutely every line of every shape but it wouldn’t be possible for a 4D being to like in 3D, it would be like us living in 2D. Above I have some 4D shapes to give you an idea of how we can represent them. It’s better to watch the inks though.

Astronomy is important because it tells us how big is the universe and how it spreads even more and when we understand that infinite distances we will learn to love and appreciate what is closest to us

What are Perseid Meteors, and why should you be excited for them this year? Let us tell you!

The Perseid meteor shower is caused by debris from Comet Swift-Tuttle as it swings through the inner solar system and ejects a trail of dust and gravel along its orbit. When the Earth passes through the debris, specs of comet-stuff hit the atmosphere at 140,000 mph and disintegrate in flashes of light. Meteors from this comet are called Perseids because they seem to fly out of the constellation Perseus.

Last year, this meteor shower peaked during a bright “supermoon”, so visibility was reduced. Luckily, forecasters say the show could be especially awesome this year because the Moon is nearly new when the shower peaks on Aug. 12-13.

The best place to view the event is away from city lights around midnight. Under a clear, dark sky forecasters predict meteor rates as high as 100 per hour on peak night. So, get outside, look up and enjoy the show!

If your area has poor visibility on the peak night, we’ve got you covered! We’ll be hosting a live broadcast about the meteor shower from 10 p.m. EDT Wednesday, Aug. 12, to 2 a.m. Thursday, Aug. 13. In addition to footage from our live skycam, the program will highlight the science behind the Perseids, as well as our research related to meteors and comets. Tune in on NASA TV or our UStream Channel.

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 :)
