The Case for Mars by Dr. Robert Zubrin

The Case for Mars by Robert Zubrin

The Case for Mars by Dr. Robert Zubrin is a good primer about everything you need to know about humanity’s attempt to colonize Mars. The author, Dr. Zubrin, is an American aerospace engineer, author, and advocate for the human exploration of Mars.

As an engineer, his book has formulas and timelines, estimates, and analyses, so you’d need at least a Freshman college or university level of math, physics, and chemistry to make sense of them all. Don’t let that stop you; because the author offers you suitable history lessons and some good arguments favour tax-funded and commercial scientific endeavours to reach Mars. According to Dr. Zubrin, a human mission to Mars is entirely within reach even using late 1950s rockets, not computing, technologies.

Dr. Zubrin advises against building a Battlestar Galactical ship for this trip. Instead, he advocates living off the land and using local resources to make a two-way mission possible

It took about 250 days for the British navy to make it to Australia for the first time. Now with proper planning, we can go to Mars within only six months! Dr. Zubrin advises against building a Battlestar Galactical ship for this trip. Instead, he advocates living off the land and using local resources to make a two-way mission possible. We can send uncrewed spaceships and equipment to Mars in advance to use local Marsian resources to make rocket fuel and oxygen a round-trip to Mars possible.

If you follow NASA and SpaceX missions to Mars, this book will give you some good foundational knowledge to enrich your experience.

Vaccine passports aren’t a punishment

Vaccine passports aren’t a punishment. They are a means to protect the population from unvaccinated individuals who are potential hosts for pathogens and variants by removing them from public spaces.

In a pandemic such as this one, a population is only safe when 90% of the individuals are fully vaccinated. That is achieved by vaccinating as many people as possible and removing the individuals who won’t vaccinate. Otherwise, the virus will keep circulating in the population forever, making people sick, taking lives, and eventually bring down the economy and other infrastructures.

No vaccine is 100% effective, but it’s a very effective layer of protection in addition to the other layers of protection. Personal choice is for when you decide whether to take antibiotics, HPV vaccine or getting a nose job, where your decision only affects you.

In a pandemic, your choice of not getting vaccinated will put people in your community at risk. If it doesn’t kill someone in your immediate circle, the pathogen in your body will eventually harm someone a few degrees removed from you.

Your personal choice ends where other people‚Äôs safety starts. That’s how public health works.
