L’être humain est fascinant car il évolue au sein de la société. Cette évolution implique la croyance, la capacité d’adaptation, la résilience et la faculté de croître. De plus, une société bienveillante encouragera également le développement durable en contribuant à la construction de la civilisation et à la paix. Pendant ce temps, l’art est parallèlement en correspondance avec la civilisation humaine puisqu’il reflète et façonne les aspects culturels, sociaux et historiques des sociétés humaines à travers l’histoire.

Cependant, l’art est considéré comme une forme d’amour et de passion, à travers laquelle les artistes s’engagent dans la communication, exprimant leurs idées et perspectives qui résonnent avec leur état d’esprit du moment. Il illumine la progression de la civilisation humaine. Les origines des arts humains, particulièrement les peintures rupestres, remontent à l’époque préhistorique. Ces créations étaient profondément associées aux modes de vie, aux cultures et aux civilisations de cette époque. Parmi les exemples très connus sont inclus la grotte Chauvet en France, la grotte El Castillo en Espagne et la grotte de Bhimbetka en Inde (Fig. 1).

De plus, les récits théologiques et culturels du christianisme ont contribué à une variété de peintures chrétiennes captivantes, allant de l’art chrétien primitif jusqu’à nos jours. La période de l’art chrétien primitif (IIe au IVe siècle) a prospéré dans les catacombes de Rome et d’autres sites funéraires. Ces peintures-là étaient principalement symboliques et représentaient des scènes dans l’histoire de l’Ancien et du Nouveau Testament. Les peintres se concentraient également sur l’expression de la confiance et de l’espoir de manière discrète au milieu des défis de la persécution et de la mortalité. Ainsi, ces peintures vont au-delà de la simple imagination car elles agissent comme des moyens de communication pour les croyants, leur permettant de se consacrer et de professer leur confiance dans le christianisme. Les scènes peintes présentent aussi la vie de Jésus Christ, comme la nativité, l’enseignement, la crucifixion et la résurrection.

Après cette période-là, le christianisme s’est tourné vers l’art byzantin (du IVe au XVe siècle) avec l’établissement du christianisme byzantin dans l’Empire Romain d’Orient. Un nouveau style artistique est apparu sous la forme de perspective plate et abstraite, avec des arrière-plans richement ornés et une utilisation extensive de feuilles d’or et de mosaïques pour transmettre les récits. Dans l’ensemble, les peintures influencées par le style byzantin dans le christianisme ne se limitent pas à l’esthétique, puisqu’elles englobent pareillement une connexion spirituelle avec Jésus Christ, la Vierge Marie et les saints, comme illustré sur Fig. 3.

The reality of COVID19 raises a critical question in the mind of Adam Ethan Loeb a young Belgium boy regarding the extinction of the human person. This questions birthed “Adam’s Dream” which for him will help in “Saving Humanity From Extinction”, by “Availing a Multiplanetary Education for the present and Future Generations
This 12year old boy highly influenced by Elon Musk and Peter H. Diamandis believes that a multiplanetary existence could have prevented the spread of coronavirus.
This young Space Enthusiast believes that since they are the future of tomorrow, well structure Young Space Education System should be availed because the Future is Faster than we think.

In explaining his vision Adam explained, “Adam’s Dream is my vision about the future with regard to preserving our kind and other living things. This idea struck my mind during this novel coronavirus outbreak. As the spread increases day in and day out, I was scared and asked my mum the question, “mum, do you know that living in space could have saved or preserved humanity better”? My reason is, if we become multiplanetary, it will solve the problem of overpopulation and make the human person more creative and resilient.

Thus, in this project, I will be preparing my generation and the ones to come to become multiplanetary Species. We have many Space Advocates; there is no proper attention giving to the younger generation. The future is obscure for my generation, and I want to lead them to light through the help of those who know better in compliance with “Adam’s Dream” rooted in Saving Humanity from Extinction by Availing a Multiplanetary Education for the present and Future Generations. In this, we can have a Sustainable “Kosmic” Environment for Prosperous Living.

Reading the works of Elon Musk gave me the conviction that as a Multiplanetary Activist, I can do this. Elon started thinking about Space at 14 years; I began at 10years. He is no doubt my number one role model followed by Peter H. Diamandis with my effort in understanding the teachings of Sara Seager – Planetary Scientist, K. Radhakrishnan, Carolyn Porco, Jill Tarter, Neil deGrasse Tyson, Liu Yang, Steve Squyres, Louis Allamandola, and David Spergel. I will have a better approach to harnessing the reality of Multiplanetary for my generation on those to come. The reality of Space is faster than you think.”

The U.S. space agency National Aeronautics Space Administration (NASA), European Space Agency (ESA), and Japan Aerospace Exploration Agency (JAXA) are inviting coders, entrepreneurs, scientists, designers, storytellers, makers, builders, artists, and technologists to participate in a virtual hackathon May 30–31 dedicated to putting open data to work in developing solutions to issues related to the COVID-19 pandemic.

During the global Space Apps COVID-19 Challenge, participants from around the world will create virtual teams that – during a 48-hour period – will use Earth observation data to propose solutions to COVID-19-related challenges ranging from studying the coronavirus that causes COVID-19 and its spread to the impact the disease is having on the Earth system. Registration for this challenge opens in mid-May.

“There’s a tremendous need for our collective ingenuity right now,” said Thomas Zurbuchen, associate administrator for NASA’s Science Mission Directorate. “I can’t imagine a more worthy focus than COVID-19 on which to direct the energy and enthusiasm from around the world with the Space Apps Challenge that always generates such amazing solutions.”

The unique capabilities of NASA and its partner space agencies in the areas of science and technology enable them to lend a hand during this global crisis. Since the start of the global outbreak, Earth science specialists from each agency have been exploring ways to use unique Earth observation data to aid understanding of the interplay of the Earth system – on global to local scales – with aspects of the COVID-19 outbreak, including, potentially, our ability to combat it. The hackathon will also examine the human and economic response to the virus.

Love it or hate it, Starlink might be the biggest space undertaking ever once completed. The combined mass of the Starlink satellite constellation exceeds any prior space endeavor. The SpaceX network provides global satellite Internet access will weigh in more than any other prior space program. The constellation consisting of thousands of mass-produced small satellites in low Earth orbit adds up quickly. Each Falcon 9 launch gets packed full of sixty Starlink satellites. The satellites neatly fit in both size and mass limitations of the Falcon 9.

In 2018, The Federal Communications Commission granted SpaceX approval to launch up to 4,425 low-Earth-orbit satellites at several different altitudes between 1,110km to 1,325km. The following year, the FCC approved a license modification to cut the orbital altitude in half for 1,584 of those satellites. The lower altitude for the Starlink satellites reduces the latency of the Starlink. Yeah initial Starlink will be nearly the mass of the ISS.

MANILA, Philippines — A dengue case forecasting system using space data made by Philippine developers won the 2019 National Aeronautics and Space Administration’s International Space Apps Challenge. Over 29,000 participating globally in 71 countries, this solution made it as one of the six winners in the best use of data, the solution that best makes space data accessible, or leverages it to a unique application.

Dengue fever is a viral, infectious tropical disease spread primarily by Aedes aegypti female mosquitoes. With 271,480 cases resulting in 1,107 deaths reported from January 1 to August 31, 2019 by the World Health Organization, Dominic Vincent D. Ligot, Mark Toledo, Frances Claire Tayco, and Jansen Dumaliang Lopez from CirroLytix developed a forecasting model of dengue cases using climate and digital data, and pinpointing possible hotspots from satellite data.

A team of transatlantic scientists, using reanalyzed data from National Aeronautics and Space Administration’s Kepler space telescope, has discovered an Earth-sized exoplanet orbiting in its star’s habitable zone, the area around a star where a rocky planet could support liquid water.

Scientists discovered this planet, called Kepler-1649c, when looking through old observations from Kepler, which the agency retired in 2018. While previous searches with a computer algorithm misidentified it, researchers reviewing Kepler data took a second look at the signature and recognized it as a planet. Out of all the exoplanets found by Kepler, this distant world – located 300 light-years from Earth – is most similar to Earth in size and estimated temperature.

This newly revealed world is only 1.06 times larger than our own planet. Also, the amount of starlight it receives from its host star is 75% of the amount of light Earth receives from our Sun – meaning the exoplanet’s temperature may be similar to our planet’s, as well. But unlike Earth, it orbits a red dwarf. Though none have been observed in this system, this type of star is known for stellar flare-ups that may make a planet’s environment challenging for any potential life.

From the US territory Guam, sightings came in of a fireball falling from the sky. The strategic location of Guam and the U.S. military stationed there has drawn attention for years. Guam thrust into the limelight during heightened tensions with North Korea. In August 2017, North Korea launched missiles that flew over Japan and into the northern Pacific Ocean in an apparent attempt to threaten the US territory of Guam. North Korean leader Kim Jong Un did not follow up on his threats, but a fireball came crashing down from a different source.

Local officials quickly released an announcement indicating the Chinese Long March Launch as a likely source of the fireball. Indeed, an Indonesia satellite launched on a Chinese rocket came crashing back to Earth. The satellite failed to reach orbit. The failure of the new communications satellite for Indonesia to reach orbit marked the second failure for china’s space agency in less than a month, state media reported April 9.

It is unlike the Chinese Long March 3, workhorse of the Chinese launch industry, series rocket to fall. According to the Xinhua News Agency, the rocket lifted off at 7:46 p.m local time from China’s Xichang Satellite Launch Center in the Sichuan province. The rocket traveled according to plan during the first and second stages. The Rocket third stage experienced abnormal conditions.

The Indonesian joint venture of Indosat Ooredoo and Pasifik Satelit Nusantara contracted with China Great Wall Industry Corporation for the high throughput satellite. The scope of work included building the Palapa N1 satellite and replacing the Palapa-D satellite at the 113° East geostationary orbit.
Mercury has only been visited by two spacecraft so far… Credit NASA

The ESA probe BepiColombo flew past Earth on the way to Mercury. The probe launched in 2018 and made the last visit of our home before continuing onward to the final destination. The spacecraft needs to shed velocity to arrive at Mercury in 2025 at a velocity to enter orbit. The spacecraft will make multiple additional planetary flybys of Venus and Mercury to slow down to enter orbit.

In space travel, mission planners need to balance mission resources. The amount of fuel required to either speed up or slow down a spacecraft greatly impacts the cost of the mission. Using a longer flight path can reduce the propellent requirements for a mission but the mission will take longer. Gravity assists can, therefore, allow a spacecraft to be launched on a cheaper, less powerful rocket.

Gravity assist flyby?

A Gravity assist flyby has other names including a gravitational slingshot, gravity assist maneuver, or swing-by. Gravity assistance maneuvers increase or decrease its speed or redirect the orbital path. The spacecraft slingshots around another object with a gravitational field and transfers some of the energy during that slingshot. In the case of BepiColombo, the spacecraft needs to slow down to be captured by Mercury…

NASA may have sidelined the Lunar Gateway for a return mission to the Moon, but it is not stopping the momentum. NASA has awarded several contracts for the Lunar Gateway including the most recent one to SpaceX. This demonstrates the growing capabilities of New Space companies to capture contracts and complete missions.

This contract award is another critical piece of our plan to return to the Moon sustainably. The Gateway is the cornerstone of the long-term Artemis architecture and this deep space commercial cargo capability integrates yet another American industry partner into our plans for human exploration at the Moon in preparation for a future mission to Mars.

NASA Administrator Jim Bridenstine in a press release statement about the award to SpaceX.

NASA Awarded SpaceX the first Artemis Gateway Logistics Services (GLS) contract. The award for resupply services to the Gateway will require delivery of goods to a Near Rectilinear Halo Orbit (NRHO). Not sure what a NRHO orbit is? A NRHO is a highly elliptical orbit that takes about 7 days for each orbit. Want some more details, just click here: Near Rectilinear Halo Orbit (NRHO). There are a few options for NRHO orbits, but NASA is leaning towards the L2 9:2 lunar synodic resonant southerly Near-Rectilinear Halo Orbit (NRHO) which would be the likely location of the lunar Gateway. A simplification of the orbit is shown below.
