Calling All Young People! Physics Is Phun!

If kids are finding science studies boring and exhibit no interest in pursuing a career in something like physics, they just haven’t made the right connections! Look, the future of our planet’s survival depends on every generation producing fantastic scientific minds with a passion for discovery. And, trust the gringa, science, especially physics, is anything BUT boring! I mean, just check out this amazing GIF and video that illustrate physics in action. One looks like dots traveling in a straight line but they are actually traveling on curves. The other looks like the dots are traveling in a circular pattern but they are actually traveling in a straight line:


Now that the gringa’s got your attention, what exactly can a person do as a physicist? Well, you can create really cool art like this or you could work for other people. If you work for NASA you can follow their astrophysics goal:  “Discover how the universe works, explore how it began and evolved and search for life on planets and other stars.” To do that involves all sorts of interesting work like:

  • Stargazing through incredible observatories like: Hubble Space Telescope, Chandra X-ray Observatory, and the Spitzer Space Telescope
  • Work with teams from all over the world: European Space Agency and Japan’s JAXA space agency
  • Perform all sorts of wacky experiments to test theories about things like: black holes, the Big Bang, dark matter, dark energy, existence of extra-terrestrial life, suitability of distant planets to support life
  • Design any manner of dangerous stuff mom and dad won’t let you build in the garage: rockets, lasers, rocket fuel, robots, super colliders that annihilate atoms

So kids, get excited about science! If it’s boring in the classroom, search for inspiration. There are folks like physicist Derek Muller who makes science loads of fun. On his blog and YouTube channel, “Veritasium”, you can learn about science in a way that is interesting and also relevant to what the world needs to day. Check out one of the gringa’s favorite videos of Muller’s (grapes + microwave = plasma):

Look, kids, the truth is agencies like NASA needs you. Your mom and dad need you. The entire world needs you. Let’s face it, the world is in need of some major repair. The days of Batman and Flash Gordon are over. The heroes the world needs now are scientists. So, put on your goggles (and a cape if it inspires you) and get crackin’.

A New Moon For A New Age

Most people think Earth’s moon is old news. However, what the public may not realize is that NASA has a rover active on the Moon, the Lunar Reconnaissance Orbiter Camera (LRO). The gringa will call the rover “Elroy” for your reading pleasure.

Elroy has a new exhibit on display at the National Air and Space Museum in Washington, D.C. that reveals that our Moon is anything but boring. What with Mars and black holes and parallel universes getting so much attention, it’s easy for our little ol’ Moon to get lost in the mix. The gringa wants to give it some glory that is long overdue.

One thing that is interesting about the Moon is that it undergoes such frequent change. It seems to get blasted all the time by meteors and such. The images on display in the exhibit show the formation of new impact craters (kind of scary when the gringa considers its proximity to home! The Moon may very well be our shield!). Recent volcanic activity has also been detected. And, most curious of all, is evidence that the Moon’s core may be cooling which has caused it to shrink and crack the crust of the Moon’s surface.

Elroy is a busy little rover. So busy, in fact, that there are too many images for this single exhibit. So, in addition to the favorites that were selected for display, there is a large screen which projects lunar images that are updated daily.

Since 2009, in addition to a fabulous photography collection, Elroy has also collected environmental and geological data with the seven other instruments he is equipped with. Elroy’s mission is to map the entire surface of the Moon. Even the legendary “dark side” of the Moon.

You see, one reason the Moon remains so mysterious is because it has a “backside”. Yes, we never get to see the Moon’s rear-end. We always see only one physical side of the Moon. Now, this is not because the Moon hangs suspended in space and never rotates. It’s just that it has a rather peculiar rotation cycle.

Millions of years ago the Moon spun around much faster. The pull of Earth’s gravity has caused it to slow down. So much so that its rotation cycle now matches its orbit cycle.  These cycles take 27.3 Earth days. However, observed from Earth it takes 29.5 days. (Don’t expect the gringa to get into that mystery here! You can research it yourself by clicking on… Understanding the moon phases). So, since the orbit and rotation cycles are exactly matched, as the Moon travels about the Earth, at night, when we see it, the same side is always presented to Earth.

However, for serious stargazers with top-notch telescopes, you can get a peek at a sliver of the hidden aspects of the Moon. Since the Moon is not “round and flat” like a coin but is actually elliptical, like a ball, at just the right time there is a speed differential when the Moon is farthest from Earth, thereby its rotation speeds up a bit because of a little less gravity drag. This causes what scientists call a “rocking” motion and an extra nine percent of the Moon’s surface is visible. But now, thanks to Elroy, all Earthlings can see just exactly what is on the Moon’s backside which is not “dark” after all, except during the cycle of a full moon when the Earth is blocking all sunlight.

Only two years into its mission NASA declared Elroy a complete success. Over four billion measurements were used by Elroy to complete a topographical map of the entire Moon. Elroy’s instruments determined that the coldest spot in our entire solar system is right smack on the Moon. It is found inside the shadows of Hermite crater which is located near the north pole. It is a bitter minus 415 degrees Fahrenheit. The gringa hopes Elroy was wearing his mittens.

Elroy is not just taking photos and temperature readings. The rover is also looking for water deposits, such as ice, and searching for fuel resources such as hydrogen. In preparation for future manned Moon missions, environmental radiation levels are also recorded.

So, the next time you gaze up at the Moon, give Elroy a salute. He is still on the job!

NASA Needs You!

Do you love anything that flies? Are you also a person who can organize and plan just about anything that, to others, seems a chaotic mess? Then NASA needs you.

Perhaps you like robots. Perhaps you like robots so much you’ve even stepped up your game and have built a few. Maybe you’ve got some big ideas and spectacular dreams but don’t know what to do with them. Well, NASA needs you.

Do you enjoy go-carts? Ever driven them? Worked on them? Built one? Did you enjoy all that tinkering? NASA needs you!

Are you a computer geek? Do you fantasize about putting all that keyboard pecking to use for the future of all humanity? I’m tellin’ you, NASA needs you!

Do you stargaze, with or without a telescope? NASA needs you!

NASA has all sorts of active challenges. These are opportunities for the general public to show the space agency just what they’ve got! Here’s your chance! You’re big break! If you have a crazy lab or workshop that you escape to where you invent all sorts of weird gadgets, you simply must read on because the gringa has got a treat prepared just for you! (Or a friend of yours, you can always pass the info along!)

Listed below are just a few of the current active challenges NASA has extended to the general public. Click on the links and explore NASA’s website if any of these challenges appeal to you!

  • “Sky For All: Air Mobility for 2035 and Beyond”. Develop ideas and technologies for the airspace of the future. Solve problems of air traffic management that will be dealing with crowded skies way beyond what we have today. Consider in your designs autonomous operations and cyber security. As a design for the future, twenty years from now it will not just be commercial airlines in the air. There will also be personal air vehicles, unmanned aircraft (drones), spacecraft and even stationary objects (such as wind turbines).

Future expectations is that air traffic management systems will be managing more than ten million aircraft in the skies. More than anything, this project is about public safety and also plans for poor weather conditions.
