The feeling of awe, which is a mix of respect and wonder, inspires ethical behaviour and has other benefits like:
For many ages, space was pristine. In 1957, the Soviet Union launched Sputnik 1 into orbit, but when the batteries died, the aluminium satellite marked the end of an unspoiled era.
According to NASA, the space above Earth is now the world's largest garbage dump. It consists of 8,000 tons of human junk, or space debris, left by space agencies over the last six decades.
A brief inventory of space debris includes: a spatula, a glove, a mirror, a bag with astronaut tools, spent rocket stages, bolts, paint chips, defunct spacecraft, and around 3,000 dead satellites, orbiting Earth at speeds of roughly 18,000 m.p.h.
Most space junk is moving in low Earth orbit (LEO), within an altitude of about 100 to 1,200 miles. This is the same space where the world's 3,000 satellites operate that power telecommunications and GPS technologies.
Some space rubble is natural micrometeoroids, like the fragment that struck the starboard payload bay radiator of the STS-115 flight in 2006.
Even tiny, untrackable micro-debris can become a problem. A paint fragment chipped off a spacecraft can move at nearly ten times the speed of a bullet and puncture an astronaut's suit, crack a window of a Space Station, and potentially destroy satellites.
A problem NASA scientist Donald J. Kessler outlined in 1978: As space becomes more packed with spacecraft and debris, collisions become more likely, creating more debris that could trigger a chain reaction of collisions. There is a possibility that near-Earth space can become a shrapnel field.
The first known case of damage happened in 1996 when a piece of European Ariane rocket struck the French spy satellite, Cerise. Many similar incidents have occurred since then.
China and companies like SpaceX, OneWeb, and Amazon aim to launch thousands of satellites into lower Earth orbits to reduce the time it takes for a signal to travel from the satellite to the user.
But some space experts are concerned that satellite mega-constellations could create more space debris. A 2017 study found that the deployment of satellite mega-constellations into low Earth orbit could increase catastrophic collisions by 50 percent.
At this point, no international rules are governing the deployment and management of satellite mega-constellations.
The Inter-Agency Space Debris Coordination Committee comprises 13 of the world's space agencies. It aims to prevent on-orbit break-ups and to remove old spacecraft from the densely populated orbit regions. But, while space debris is everyone's problem, no entity is obligated to solve it.
Cleaning up space will be complex and expensive and requires a coordinated, international effort. The most agreed on strategy among space organizations are to get rid of the big stuff first.
To clean up low Earth orbit, space organizations have proposed multiple solutions. The most promising is the ClearSpace-1 that will try to capture the junk with a robotic arm.
Plants are pretty. They are affordable and can enhance a space and encourage cleaner air, often resulting in a better mood and more focused concentration.
But for the super busy, somewhat lazy, and possibly intimated person, they can be hard to keep alive. Knowing what the plants need can help us do better.
Determine how much time, space and effort you can reasonably give to a new plant.
Then pay attention to your home's access to sunlight at different times of the day. When is it the brightest? What direction is the window facing? Is there a direct view to the sky? Even if you're sandwiched between two high-rises, certain plants thrive in low light situations.
Don't be afraid to experiment with plants. Some trial and error will make it possible to grow some plants.
Ikigai is a Japanese concept which is defined as "the reason for being." It is one who strives to have a lifestyle that is balanced with the spiritual and the practicial.
The individual's ikigai is found in the middle of the intersection where your passions and talents converge with the things that the world needs and is willing to pay for.
The most important thing to keep in mind when learning ikigai is that form follows intent.
After learning to cycle, most people won't forget how to pedal a bike even after decades.
Learning how to cycle requires higher-level thinking.
While we use muscle movement and brain connection in other activities like dancing, sports, and walking, we don' use it all simultaneously like when we cycle.
