Note:

Sun’s light travels continuously, so just calculated the time the sun’s light took (not takes) to reach each planet’s surface. Each orbit is not perfectly circular, it’s elliptical. So each planet has farthest and closest distances from the sun (perihelion and aphelion). The given distances are in average and approximate range, so as the time calculated depending on the given data.

The solar system planets in order from the Sun are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune. This has been correct since 2006 when the International Astronomy Union actually defined what a "Planet" is and also what a "Dwarf Planet" is.

There are now 5 official dwarf planets: Ceres, Pluto, Haumea, Makemake, Eris.

From 1801 to the 1845 there were up to 23 planets. These were due to the discovery of Ceres, Pallas, Vesta and Juno early in the century - all of which were classified as planets. Then around 1845-49 more bodies were discovered (Astraea, Hebe, Iris, Flora, Metis and Hygiea) as well as Neptune (1846) and over a period of a few years (within which Parthenope, Victoria, Egeria, Irene and Eunomia were discovered) it was decided that the classification of Asteroid was needed to describe the bodies in this newly found "Asteroid Belt". Once the classification of asteroid became widely accepted, we were left with the 8 planets we have today. Currently we have over 300,000 catalogued asteroids, with probably a million or more waiting to be found.

The gravity on Mars is around a third of that on Earth. Mars receives about half of the sunlight we get on Earth, but much higher levels of harmful ultraviolet (UV) and cosmic rays. The surface temperature of Mars is about -60℃ and it has a thin atmosphere primarily made of carbon dioxide.
Unlike Earth’s soil, which is humid and rich in nutrients and microorganisms that support plant growth, Mars is covered with regolith. This is an arid material that contains perchlorate chemicals that are toxic to humans.
Also – despite the latest sub-surface lake find – water on Mars mostly exists in the form of ice, and the low atmospheric pressure of the planet makes liquid water boil at around 5℃.
Plants on Earth have evolved for hundreds of millions of years and are adapted to terrestrial conditions, but they will not grow well on Mars.
This means that substantial resources that would be scarce and priceless for humans on Mars, like liquid water and energy, would need to be allocated to achieve efficient farming by artificially creating optimal plant growth conditions.
Adapting plants to Mars:
A more rational alternative is to use synthetic biology to develop crops specifically for Mars. This formidable challenge can be tackled and fast-tracked by building a plant-focused Mars biofoundry.
Such an automated facility would be capable of expediting the engineering of biological designs and testing of their performance under simulated Martian conditions.
With adequate funding and active international collaboration, such an advanced facility could improve many of the traits required for making crops thrive on Mars within a decade.
This includes improving photosynthesis and photoprotection (to help protect plants from sunlight and UV rays), as well as drought and cold tolerance in plants, and engineering high-yield functional crops. We also need to modify microbes to detoxify and improve the Martian soil quality.
These are all challenges that are within the capability of modern synthetic biology.
Benefits for Earth:
Developing the next generation of crops required for sustaining humans on Mars would also have great benefits for people on Earth.
The growing global population is increasing the demand for food. To meet this demand we must increase agricultural productivity, but we have to do so without negatively impacting our environment.
The best way to achieve these goals would be to improve the crops that are already widely used. Setting up facilities such as the proposed Mars Biofoundry would bring immense benefit to the turnaround time of plant research with implications for food security and environmental protection.
So ultimately, the main beneficiary of efforts to develop crops for Mars would be Earth.

Hello!

My honorable fellow Asgardians,

Some friends ask me what you want to do for Asgardia. So we would like to say to our friends that I have placed everything in front of you as own platform. Please carefully study about our platform once. As our slogan is that people, along with humanity, are spiritually mentally and physically fit. Spiritual growth of people along with science and engineering. Only then can there be a sense of true peace and spiritual unity. The biggest thing for this is that we should have positive energy through our eyes, ears and mouth. For this, such films should be created and such education should be done, in which science and technology as well as the spiritual development of the people and the creation of good character. And we should also make regular practice of connecting our energy with our infinite universe by purifying our nerves. If we become a culture minister, then first we will have to work according to some rules related to this. Only then we can create a good space nation.
Thank you very much to all of you!
