The Mars Curiosity Rover is one of the most successful planetary missions of all time. Here’s how NASA plans to follow that up – the Mars 2020 Rover

 

Science Objective A: Explore once potentially-habitable areas

Science Objective B: Seek bio signatures

Science Objective C: Sample Caching

Science Objective D: Demonstrate in-situ resource utilization.

And here are the instruments that will make that possible. It contains 2 cameras on the probe’s mast, one called Mastcam-Z, which is the main “eye” for the rover.

It can take 360 degree panoramic 3D views with an advanced zoom that can see something the size of a housefly from the distance of a soccer field. And the second camera is called SuperCam.

This can actually do a spectrographic analysis of a rock’s chemical makeup from over 20 feet away by burning a hole in the rock as small as the point of a pencil.

This was developed in conjunction with a team from France. PIXL, or Planetary Instrument for X-Ray Lithochemistry will examine rock and soil samples for signs of ancient microbial life and can take extremely close up images of soil samples down to the size of a grain of salt. MEDA, the Mars Environmental Dynamics Analyzer is a contribution from a team in Spain, it’s a tiny weather lab that measures wind speed, temperature and humidity and also gathers data about dust particles in the Martian atmosphere.

RIMFAX, the Radar Imager for Mars Subsurface Experiment from Norway is basically like a sonogram that see tens of meters below the ground and detect elements down to the centimeter. This will help find underground water and ice on Mars. The aptly named SHERLOC, or Scanning Habitable Environments with Raman and Luminescence for Organics and Chemicals is a big sciency way of saying it looks for signs of ancient life with UV light, much like forensic investigators at crime scenes.

Hence, Sherlock. But SHERLOC will carry a couple of interesting things with it, one is a Mars meteorite for calibration purposes.

There’s a handful of meteorites found here on Earth that we know were once a part of Mars that were blasted away in an asteroid impact, then travelled through the solar system and eventually landed on Earth.

SHERLOC is going to carry a piece of one of those meteorites to use to calibrate its laser on the Martian surface, which means this will be the first time a piece of martian rock will be returned to Mars. The other thing is it will be carrying samples of materials that may be used to make Martian spacesuits, to see how well they fare in the Martian environment. And last but definitely not least is MOXIE, the Mars Oxygen ISRU Experiment.

This is the module that will be testing in situ resource utilization techniques in the hopes of turning the CO2 in the martian atmosphere into oxygen, just like a tree. The rover will also contain a special microphone, giving us the first sound recordings from the surface of Mars.

What’s The Deal With Bitcoin? (Featuring Cooper Carr of the Cine Pile Podcast)

I covered Bitcoin, cryptocurrencies, and blockchain technology in previous videos, and one of the people who helped me research those videos was my good friend Cooper Carr.

Cooper runs his own podcast called the Cine Pile Podcast, where he and a couple of friends have “down to Earth discussions about films that matter”. I actually appeared on their podcast a while back, so you know it’s gotta be good.

But Cooper has been all about Bitcoin and cryptocurrencies for years now, so when I was researching for my video, he was one of the first people I talked to.

In this podcast, Cooper joins me to talk in depth about how he got into Bitcoin and crypto, what’s changed over the last few years and how this new paradigm is going to change in the future. It’s a fun conversation that touches on all kinds of tangents, so I hope you enjoy it.

Tom Parr – The 150 Year Old Man

Thomas Parr – also known as Old Tom Parr – lived to the astonishing age of 152. According to legend.

So did he really live to be that old? And if so, what can we learn from him? What’s the key to longevity and living past 100?

Mathematics is the backbone of all sciences, no theories or hypotheses are proven unless there is math to back it up. But there are many who believe that math isn’t real. In today’s video, we’ll break down the arguments.

From the Mathematical Physicalists to the Platonists to the Mathematical Fictionalists, we look at all the theories behind whether numbers actually exist, and what they mean.
