Energy in the Exploration of Mars






On February 18, the Perseverance rover arrived on Mars, after seven months of space navigation, and landed in the Jezero crater. This NASA tool promises to increase collect information regarding the environment of the red planet to determine the possibilities that there had been life in the past; if it can generate oxygen or if there are traces of water.

I must say it, Perseverance is an impressive piece of technology: it has 19 cameras, microphones and a drone in the form of a helicopter called Ingenuity. It weighs 1,025 kilograms and measures 2.2 meters high and 2.9 meters wide. In addition, for our analysis, it consumes 110 Watts of energy.

This is 50% more than what a laptop consumes or seven times less than what a microwave oven consumes. Surprisingly, the Ingenuity consumes more energy —350 Watts— according to NASA information.

How is Perseverance charged for exploration on Mars?

Considering that there are not many sources of energy on Mars, nor the means of development, Perseverance and Ingenuity must be very efficient and self-sustaining during their exploration mission. For the rover, the source of energy is a multi-mission radioisotope thermoelectric generator. Or, said in a very —but very— simple way, a nuclear battery.

The thermocouples of the battery convert the heat emitted by radioactive decay of a nuclear source; in this case a radioisotope of plutonium-238, into electrical energy. The generator charges two lithium-ion batteries and provides energy to Perseverance.

And, since 88 years are required for the radioisotope to reach its half-life —the unit of measurement to determine the time in which unstable atoms will survive radioactive decay—, we have a potential energy source for the rover for a while.

Why was this type of energy chosen for Perseverance?

This source was chosen over solar panels because of the operational flexibility that it would provide to the rover to operate in conditions of low solar irradiation during exploration on Mars. This assumption occurs at night, in winter or in adverse weather situations, such as sandstorms.

For its part, Ingenuity does use solar panels to charge its six lithium-ion batteries.

This experimental drone/helicopter weighs 1.8 kilograms and has only one mission: to explore the environment so that Perseverance can plan the best routes on its journey. To keep it light, it does not have any type of instrument beyond its camera and its solar panel.

NASA’s spending for the development of Perseverance was 2,500 million dollars and it will have an operation and maintenance cost of 150 million dollars per year. If we talk about its useful life being eleven years, the total amount will hover around 80,000 million pesos of 2020. Something like the entire subsidy of CFE last year.

The development and operation of the Rover Perseverance is one of the projects that will help us better understand our solar system; at the same time it puts into practice technological development in modern energy matters through the nuclear battery and the solar panels of Ingenuity. These developments are, without a doubt, important pieces to advance on the frontier of possibilities of energy use both on Earth and in space.

The Future Is Built First in Our Mind






It is 5:59 in the afternoon, in the middle of rush hour and it is raining. Juan waits for the bus at the designated stop, near his university; there is a line of people waiting. The board announces that the next bus will arrive at 6:00 in the afternoon. Exactly at the designated time, the transport arrives.

When the door opens there is no one at the entrance, only a series of systems integrated with processors, screens, sensors and cameras. To enter you pass a card that gives you your balance; if you have no balance you get off voluntarily, otherwise, the system will send an alarm and you could be admonished at the next stop.

Before, in 2021, it would have taken two hours by bus to get home. Now it takes only one hour. There are no longer traffic lights on the route; the road sensors are interconnected with each bus and each automobile that circulates. In the past, a large part of traffic jams occurred for three reasons: automobile accidents, not respecting traffic signs and a lack of road culture.

Traffic is organized by times. The interconnected systems use algorithms and plan in real time; they send stop and go signals directly to the automobiles, which process the instructions considering the central instructions, the cars around them, cyclists, pedestrians and obstructions on the road.

People have more time because traffic operates efficiently and buses arrive at the established time with a maximum tolerance of 5 minutes. The systems are also connected with other routes and the metro, so that trips can be organized and connected in several segments in an optimal way.

Elsewhere, Adriana left her office and the GPS indicates that it will take two hours to reach your destination. She is reading that book that was added at the beginning of the year to her resolutions and she is already halfway through, reading one hour daily on average, every day in traffic. She is in a taxi, but there is no one driving, the automobile is a unit that is interconnected to the company’s central system and in turn is communicated with the traffic control system from the central offices of the government.

Traffic control is very important, and not only land traffic control, but also air traffic control. Since the massive proliferation of drones a few decades ago, it is now common to see drones everywhere, from those that take photography and videos, to those that monitor traffic, without forgetting service drones that are dedicated to sending packages, making repairs on roofs and facades, fumigating and many other activities.

On the street, Javier sees in the distance a mobile autonomous business coming. An intelligent vending car that sells anything without the need for an operator or seller. This one sells coffee as if it were an old vending machine but that moves analyzing the mobility patterns of pedestrians. It is not the only thing, food, books, flowers, water, clothing, almost anything.

At her house, Laura receives a message, a package has arrived, but there is no one in the cargo truck; and it is that parcel services and food deliveries have also benefited greatly from light cargo autonomous vehicles that send their location in real time and that make deliveries automatically without any operator or delivery person, in addition to aerial delivery by drones.

We say goodbye to this quick visit to a possible future and, perhaps, not very far away. I hope that you, reader, have found this fantastic journey as entertaining as I have, and it is that the future is built first in our imagination.

Opposite Direction






If on a highway all cars are coming in the opposite direction, we probably have to reflect on whether our car is not the one going backwards. In our national energy sector, it is evident that we need to stop and reflect on why we are going in a different direction from the rest of the world.

But first, it is true that we interrupt our usual programming, and I do not forget that we still have pending to talk about dark energy in the universe, the continuation of our previous installment, to talk about more banal topics but that are of great interest to all Mexicans in our day to day: the future of the national electric industry that is about to be defined, at least for the next four years.

This first of February, holiday due to the advance of the 104th anniversary of the Day of the Promulgation of the Political Constitution of the United Mexican States of 1917, the news woke us early, as has been customary, that on Friday the 29th the President of the Republic signed and delivered to the Congress of the Union a preferential initiative to modify the Electric Industry Law.

This is the most recent of a series of attempts that the federal government has made to return the electric sector to a state not only prior to the energy reform, but further back, to 1960 when then-president José Adolfo Mateos nationalized the entire electric industry to turn it into a monopoly operated by a state company, the Federal Electricity Commission (CFE).

In fact, in December 2019, CFE presented a list of demands that outlined this plan and that began with modest actions and omissions, particularly by the Energy Regulatory Commission (CRE) and the National Energy Control Center (Cenace), so that CFE would have a “level playing field,” a euphemism with which it is intended to return to the monopoly. Needless to say, currently, the state company controls more than 80% of the country’s electric generation, more than 80% of consumers; enjoys the monopoly of transmission and distribution, has one of the most important gas pipeline networks in Mexico and receives direct capital injections from the Mexican government.

In times of poor economic performance —in part because of the COVID-19 effect on our lives and because of a series of economic decisions of the current federal administration—, where countries seek to stimulate businesses and companies through support for spending on electric energy; where economic recovery is sought, attracting investment and generating jobs, and where it is sought to paint it as a green recovery, the actions derived from this preferential initiative place us in the opposite direction of the world.

The probability that this course of action will lead us to an imminent collision with other automobiles (countries) or that we come out with permanent damage (loss of competitiveness and country credibility) is high. On the one hand, the statement of reasons clearly dictates, without euphemisms, that the reform to the Electric Industry Law is carried out to strengthen CFE. This goes against the principle of free competition and free concurrence protected in constitutional article 28. Since 2013, generation and commercialization were removed as exclusive monopolies of the State in the Magna Carta to be considered economic activities under the regime of free competition.

Faced with a practice that violates the principles of economic competition that strengthen a State company, we could not rule out that American and Canadian companies are planning to take this issue to a controversy within the T-MEC. With a new government in the United States that actively promotes global decarbonization and the energy transition, then a crash is imminent caused by a vehicle, Mexico, that goes in the opposite direction, thinking that all the others are going in the opposite direction.

The problem is that not only has the driver not realized it, but he thinks that everyone else is the one going backwards. We return to our usual programming next week.
