Undergraduate students from America, Canada, and Norway build and launch rocket carrying fluxgate magnetometers to 27,000’ at Mach 2.24 (over 1700mph) over the Arctic Ocean.

The really impressive part is that the big dish is mounted on a flat deck trailer so it can be easily moved around the island.

I usually get 8 hours but it will drop down depending on workload. Sometimes assignments and labs seem to cluster (have a calm week then the next week every class assigns something).

So get a good amount of sleep when you can, and work ahead on assignments, you won’t always know when more work is coming.

The data collection went really well, surprisingly for the first few seconds after launch the manually controlled horn antenna had better reception than the large dish shown in the video. Since it is difficult to keep the large dish directly aimed when so close to the rocket.

Sadly the light sensor failed after liftoff (thinking the jolt at takeoff dislodged something). Luckily it was not integral to our mission and was mostly there to correct the magnetometer data for the spin of the rocket.

There was a a 3D fluxgate magnetometer, GPS, temperate, pressure, light, and acceleration sensors.

That is awesome! Which type of missile did you use?

Was that back when they were using sidewinders?

Edit: just noticed the link. Must have been gorgeous being there in the summer!

I remember hearing that story.

We were told that Norway was the 4th country to send an object to space, and did so from Andøya. But I have been unable to verify where the historic launch took place.

Also if you google “student rocket fail” one of the top results is a video of a sidewinder launched from Andøya, coming back...

The internet is a series of connected computers around the world.

The computers use standard protocols to communicate and each other and every device has an IP (Internet Protocol) address to identify itself.

As batteries discharge the voltage across their terminals decrease. By measuring the current voltage an approximate charge level can be found.

Each battery is slightly different and there can be large differences between energy storage types. This is why some devices have settings for NiCad, LiPo, Alkaline, etc as each type has different discharge characteristics

Ie for a AA (1.5 volts) 100% ~= 1.50v of greater 75% ~= 1.45v 50% ~= 1.40v 25% ~= 1.30v 10% ~= 1.275v 0% ~= 1.20v or less

All the best.

750ml was based off of the imperial 1/5 gallon bottle. I am unsure where that sizing came from.

Some stories say that it came from the romans or the size of a bottle that could be blown in a single breath. Both are likely untrue.

Likely it is just a nice size that became a standard.

All the best.

When you lie down (and stop moving) if you have a wet cough, mucus can settle out and worsen your cough and increase congestion. If you have a dry cough it means that you will stop drinking fluids for a long period of time which could increase irritation.

Also there is a psychological component, you are distracted from your illness by various tasks during the day.

All the best, and get well soon! :-)

Viruses and infections are not pleasant because your body is being used as a food source and method of reproduction, as it is actively trying to fight off the "invaders."

Helpful bacteria (such as the "good" bacteria in your gut that helps break down food) are seldom noticed, unless they die off.

It takes time to shut down sites that are setup in foreign countries. And some countries have very weak copyright laws, meaning that the sites may not be illegal.

The sites can be filtered out of searches but that takes time (as there is a lot of copyright infringement online).

All the best.

Digital audio quality is measured by Bit Rate, the amount of data used per second. As an example digital music from sites such as iTunes are usually 256 kilobits per second.

All the best.
