How Much Water is Needed for a Mars Mission?

When considering the shipment of water to Mars in anticipation of a 26-month astronaut mission, the task may appear straightforward. However, determining the required volume presents a complex challenge. Many estimates tend to overstate the amount. In this analysis, I aim to establish a more conservative estimate.

To begin, I must calculate the quantity of water an individual would need for all daily activities during the mission, not limited to drinking. This involves making educated assumptions, taking into account that Mars has less gravity than the International Space Station (ISS), which could affect water requirements. For simplicity, let's assume that water usage on Mars will not exceed that on the ISS, even if the astronaut were to be in a medically induced coma for an extended period due to unforeseen circumstances.

Astronauts aboard the ISS typically use approximately 12 liters of water per day. NASA recently reported a remarkable achievement—a 98% water recovery rate on the ISS. This means that only 0.24 liters are lost daily. One might assume that this loss could be linearly extrapolated over the mission's duration. However, it's essential to consider the time required for water reclamation and processing. Let's assume a conservative 24-hour delay in recovering water used the previous day. Consequently, an additional 12 liters must be sent to account for this "waiting" water. We are also assuming no significant water rationing and that a 98% recovery rate can be achieved on Mars, although this may be more challenging given Martian conditions. After taking all these factors into account, I have determined that a minimum of 199.2 liters of water is required for the astronaut to survive the 780-day mission on Mars.

Moreover, it is noteworthy that November 28th is Red Planet Day—an event of cosmic significance. You can celebrate by enjoying a Mars bar, reading Mars-themed literature such as "The Martian" and "Stranger in a Strange Land," baking red velvet cupcakes, or simply gazing at the night sky and contemplating Mars. It is essential to note that Mars will be positioned too close to the sun to be visible in the night sky on that day. Nevertheless, this fortuitous alignment with the solar calendar coincides with an auspicious launch window for potential Mars missions.

The Story of the song "Computer Love" by Zapp and Roger (with Charlie Wilson)

In the heat of the mid-1980s music scene, a friendly rivalry blossomed between two bands: Zapp, led by the innovative Roger Troutman, and the Gap Band, fronted by the soulful Charlie Wilson. While they often found themselves sharing the same stages, their music was distinguished by their unique styles. Roger Troutman was renowned for his groundbreaking use of the talk box, a tool that transformed his voice into a distinctive, futuristic echo. Charlie Wilson, on the other hand, was known for his robust, soulful vocals that left audiences in awe.

During a routine sound check, Troutman approached Wilson with a question. "Hey man, what should I do next?" he asked. Despite the surprise, Wilson, amused, responded candidly, "I don't know, I don't care," eliciting laughter from both. However, recognizing the sincerity behind Troutman's question, Wilson suggested a direction that would stretch Troutman’s usual style: "You should do a ballad."

Troutman was taken aback. A ballad was far from his traditional vibrant, funky tunes. However, trusting his friend's intuition, he considered the possibility and finally asked, "Ok, what kind of ballad should it be?" Wilson suggested a fusion of styles, maintaining a mid-tempo beat that would still retain Zapp's signature funk. The seed of the idea was planted.

Three days passed before Troutman's inspiration struck. In the early hours following a late-night show, around 3 a.m., he phoned Wilson, his voice brimming with excitement. "Man, I got this, come on, come down to the studio." Though initially reluctant due to the late hour, Wilson agreed, intrigued by his friend's enthusiasm.

Heading to Roger's studio raised a fair share of doubts for Wilson. Given their relationship and the fact that they were signed to different record companies, Wilson was unsure how this unconventional collaboration would be received. Regardless, the potential for creating something unique won out, and he set out for the studio.

The moment Charlie arrived, he was greeted by an entrancing rhythm. Troutman had composed a beat that embodied the mid-tempo, funky ballad style they had discussed days before. The rhythm instantly resonated with Wilson, sparking his creativity, leading him to contribute a complementary bass line that accentuated the track's depth and groove.

As the song structure fell into place, they began to experiment with vocals. Despite his usual lead singer role, Wilson took a step back to support Troutman's distinctive talk box melodies. The result was an electrifying blend, a harmony of the traditional and the futuristic, manifesting as a unique sonic blend that showcased both their talents.

Overwhelmed with the success of their collaboration, Troutman was moved to express his gratitude. In a sincere, spontaneous gesture, he handed Wilson all the money he had in his pocket. That night, under the dim studio lights, a new chapter was written in the annals of electronic funk and R&B. A testament to friendship, respect, and shared creativity was born, encapsulated in the iconic song they named "Computer Love".

"Computer Love" was a fusion of Zapp's electronic funk, amplified by Troutman's unique talk box techniques, and the soulful essence of Wilson's vocal prowess. This mix, initially sparked by a friendly conversation, resulted in a track that broke boundaries, stood the test of time, and continues to influence artists across genres. It stands as a testament to their shared respect, friendly rivalry, and mutual love for music, reminding the world of the beauty that lies at the intersection of friendship and creativity.

That was in 1983, and in 1985, the song was released.

Reflecting on the Past and Looking to the Future of Personal Healthcare

After quitting Twitter due to the constant nonsense caused by Elon Musk, I decided to revisit my long-abandoned blog. It can still be used to share information with those who are interested.

Upon going through my account, I realized that I haven't used it in 13 years! It's crazy how time flies by, yet some things remain the same. However, I did stumble upon an old post from 2010 (see below) where I predicted what would happen in 2020. The post was in my drafts, and it was incomplete. I wanted to finish it up, but I must have abandoned the blog before publishing, or maybe I needed more time to think about it. In any case, I think my first prediction was pretty accurate.

Personal healthcare is alive and well in today's world, with people having blood pressure and medication monitors connected to the internet. Your watch and phone can measure your blood pressure, body fat percentage, oxygen levels, and much more. People can even hook up a blood sugar monitor to their phone. There is also an app on your phone where you can send your physician your health data. While there are no handheld bacteria analyzers available for home use yet, some devices are now available but are expensive. So, I wouldn't quite call those personal healthcare devices just yet. The paper just came out in 2018, so I suppose it takes a while before these things gain trust. Additionally, the state of the art is pretty clunky now, relying on the molecules fluorescing instead of some optical or image recognition analysis, which would make this more useful.

Just imagine if in remote villages, people could detect some novel bacterium or virus by using a microscope hooked up to their phone. We're not there yet, but with the advent of AI and its subsequent growth and incorporation into almost everything nowadays, we could potentially get there quickly.

In these uncertain times, I wouldn't dare make any predictions. So much change is happening now that in another ten years, we'll likely look back at this time and either consider it the Stone Age or the good times. In any case, I'll leave the predictions to the younger generation.

Predictions for 2020

In the next decade, I can see the following: 1. Personal healthcare One has to only look at the Automated External Defibrilator (AED) to realize that the world of healthcare is getting more technologically advanced. Previously, defibrilation could only be done by trained, licensed professionals. However, computers have made it simple enough for the average person. Since computers have made the AED possible, I think the next frontier will be a bacterium analyzer

Hulu, the self-interested friend

Hulu, are you even listening to me? Many times you've asked me if this ad is relevant to me. Many times I've answered 'No'. Especially when you give me advertisements for alcohol. I don't drink alcohol, so no ads about alcohol please. And I also told you 'No' to many ads about pork or bacon or ham. I don't eat pork except on a rare occasion, and I have told you many times that I don't like it. Why aren't you listening? Send me advertisements about Xbox, about websites, about cars, fine. But please, stop with the onslaught of alcohol and pig meat. I'm not buying it, so you're wasting your time!
