Is a ‘Warp’ Drive Feasible?

We have all heard of Warp or other Faster Than Light (FTL) drives in science fiction, but are they really possible?

This short (11:54) video goes into the details of the Alcubierre Drive. While so far this drive is just theoretical, there is a strong technical basis for the drive. Certainly there are several barriers to building one of these today, but there are new achievements and discoveries every day that may break down some of these.

There has been some experimental results out of NASA that tends to support some of the aspects of the Alcubierre Drive, but at this point the Alcubierre Drive is mostly theory.

Finding the ISS

Space Travel Space International Space Station Iss

If you are interested in space, you may have tried to get away from the city lights and look up at the night sky. One of the bright objects in orbit is the International Space Station (ISS).

The ISS is in a fast orbit of the Earth, traveling at over 17,000 mile per hour. This means that the ISS completes an orbit about every 90 minutes. If you are in a spot that is relatively free of light pollution, seeing the ISS is easy.

To plan ahead for such an excursion you can use the “Spot the Station” site from NASA. You can enter where you will be into the site and it will then give you a list of the dates and times the ISS will be visible from that location. The site also gives you directions as to where to look for the ISS in the evening sky.

You can even sign up for alerts for when the ISS will be passing within view of your location. Taking advantage of this would be a great way to involve kids in STEM activities. For me the current closest location with a list of sighting opportunities is for Georgetown, TX, just a few miles north of where I live. The next viewing opportunities will be at:

“Into the Unknown”- The Story of the James Webb Telescope

Space – This video is a great, 38+ minute story of NASA’s James Webb Space Telescope (JWT) which is scheduled for launch in 2018. The video has a good explanation of why the infrared capabilities of the JWT will vastly extend our view into the universe. It is also hoped that by identifying the gasses in exoplanet atmospheres it will be able to discover any exoplanets that support life.

Popular Engineering Related Channels on YouTube

EWeek – With this being the first day of Engineers Week 2017 I thought that these videos and YouTube channels might be of interest.

  1. Grant Thompson’s YouTube channel “The King of Random” includes videos with a range of experiments and DIY projects. Some recent titles are : “Making Homemade Missiles That Explode“, “Is It a Good Idea to Make Party Poppers With Hydrogen?” and “Making Glass Vacuum Chambers Implode“.
  2. Bill Hammack’s YouTube channel “engineerguy” where the University of Illinois Chemical Engineering professor gives “the engineering details of all the stuff you wanna know about“. From his web site: Make called Bill a “brilliant science-and-technology documentarian”, whose “videos should be held up as models of how to present complex technical information visually” Wired called them “dazzling.” Scientific American’s blog called him a “smart, easygoing everyman with a firm understanding of the science.”
  3. Jason Fenske’s YouTube channel “Engineering Explained” has a more narrow focus on the subject of “How Cars Work”.
  4. The YouTube channel “Cody’s Lab” includes various experiments and adventures, most science or engineering related.
  5. NASA’s “NASA Goddard” YouTube Channel features views of various NASA technology. Expect to see the latest in NASA’s research into planetary science, astrophysics, Earth observing, and solar science on the channel.
  6. The YouTube channel “SciShow Space“, as the name implies, focuses on space exploration. The hosts, Hank Green, Caitlin Hofmeister, and Reid Reimers, cover topics ranging from what happened after the ‘Big Bang’ to the latest space related news.
  7. The “Numberphile” YouTube channel from the Mathematical Sciences Research Institute (MSRI) covers a variety of mathematic topics.

Some of these may be good to share with K-12 students interested in STEM careers.

Art, Music, Space – Visions of Harmony

I came across this video from Apple Music this morning. As it says, it is inspired by Nasa’s Juno Mission and merges music, art and space science. It is less than 9 minutes, but a nice video.

If you are interested in space, you will enjoy it. I am really glad to see that Apple has produced this video. I think it is another way to connect K-12 students with science and technology.

Further explanation of the EmDrive

I have mentioned the EmDrive several times in articles on space propulsion. The EmDrive is in the news again because a peer-reviewed paper on the drive has been submitted by NASA’s Eagleworks.

That does not mean that the EmDrive has been proven to actually work, but it does mean that it is getting some serious scientific attention. The video above is a good overview of the EmDrive by physicist Scott Manley. He talks about how the EmDrive is supposed to work, as well as the physics that says that it shouldn’t. (Manley has his own YouTube channel).

If you have interest in the EmDrive, it would be worth your time (about 16 minutes) to watch this video.
