The History Of Satellites Explained

Ever since humanity first began to theorize about the nature of space and our planet's place within it we have dreamed of placing objects in the heavens looping the planet, even when we believed it incorrectly to be the center of the Universe. Around 1610, German astronomer Johannes Kepler first used the term "satellite" —  a Latin word meaning "one who escorts or follows after an important person"  —  to describe the moons orbiting Jupiter.

What is a satellite and how do they stay in orbit?

Satellites can sit in different orbits around the Earth depending on what their function is.

Geostationary (GEO) satellites orbit Earth at an altitude of 22,236 miles and rotate at the same rate as the planet locked to its equator. Low-earth orbit (LEO) satellites, on the other hand, orbit at an altitude of between around 100 miles and 620 miles.. These satellites have a bit more freedom in the path they take around the planet, but can spend time over unoccupied areas like deserts or oceans, so communications roles are reserved for satellites in GEO  orbits. One of the key aspects of placing a satellite into space is knowing it will stay there in orbit around the planet. As mentioned above, the theories that underlie this were formulated as early as the 1600s in the work of Kepler and Newton. The National Environment Satellite Data and Information Service (NOAA) satellite stays in orbit by achieving a perfect balance between velocity and the gravitational pull that our planet exerts on it. The closer to Earth a satellite orbits, the more rapidly it has to move to stay one step ahead of this gravitational pull. According to the European Space Agency (ESA), LEO satellites orbit at a speed of around 7.8 km per second — taking about 90 minutes to fully circle Earth.

The first artificial satellite

The first artificial satellite, Sputnik 1, was launched from Baikonur Cosmodrome at Tyuratam, Kazakhstan  —  which was at the time part of the Soviet Union  —  on October 4, 1957. The Russian satellite  —  with a name that means "companion"  —  was the first in a series of four satellites launched as part of the Sputnik program. An aluminum sphere with a diameter of 58 centimeters, Sputnik 1 had four whip-like antennas between 2.4 meters and 2.9 meters long, which almost resembled "whiskers" from one side of the craft. One of the main roles of Sputnik 1 was to collect data regarding the density of the upper layers of the atmosphere and how radio signals travel through the ionosphere  —  the ionized part of Earth's upper atmosphere. The craft was capable of detecting meteoroids but failed to spot any in the three weeks of operation before its satellite transmitters stopped operations after its onboard chemical batteries failed. After completing around 1,400 orbits of Earth over 92 days, Sputnik 1 dropped out of orbit from an altitude of around 600 miles above the planet, breaking apart during its descent. 

NASA enters the satellite race

A few months after the successful launch of Sputnik, on the last day of January 1958, the United States would place its own satellite in orbit. NASA's Jet Propulsion Laboratory (JPL) at the California Institute of Technology (Caltech) built the craft  —  designated Explorer 1   — which led to James Van Allen's discovery of radiation belts around Earth held in place by the planet's magnetic field. On its website, JPL describes the launch of this satellite, Explorer 1. It writes: "A quick response to the Soviet Union's launch of Sputnik 1, Explorer 1's success marked the beginning of the U.S. Space Age." Its cosmic ray detector, provided by Van Allen made Explorer 1 the first satellite to carry science instruments into orbit. Explorer 1 revolved around Earth in a looping orbit between 220 miles to 1,563 miles above Earth. The 203 cm long and 16 cm wide craft made an orbit every 114.8 minutes and a total of just over 12 and a half orbits per day. NASA says Explorer 1 made its final transmission on May 23, 1958. Almost 12 years later on March 31, 1970, the craft entered Earth's atmosphere following over 58,000 orbits of the planet.

Observing Earth's weather from space

 

One of the most common and important jobs for satellites is the monitoring of Earth's weather. While the first weather imaging satellite entered the planning stages in 1946, it would take 14 years to implement. On April 1, 1960, NASA launched TIROS-1 (Television Infrared Observation Satellite). TIROS was the first weather satellite to be designed by NASA but was beaten to orbit by Vanguard 2  —  which launched on February 17, 1959, as part of the U.S Navy's Project Vanguard. Not only did Vanguard 2 mean that the U.S. had a weather satellite before Russia, but the craft also remains in orbit to this day and is expected to remain around Earth for as long as 300 years. Vanguard 2's primary mission was to observe cloud cover on Earth from space. The mission of TIROS was to test the feasibility of weather satellites and to try out experimental television techniques designed to develop a worldwide meteorological satellite information system. TIROS-I would not have the longevity of Vanguard 2, reaming operational for only 78 days. Yet in this period the craft was able to prove that satellites could be useful tools for surveying global weather conditions from space.

Information and entertainment in the space age

The landscape of our entertainment industry would be completely different today if not for satellites, as would the way we communicate information across the globe. As mentioned above, speculation about the use of satellites to transmit information began at least a decade before the first artificial satellite had made it to orbit. It would take until 1962 for the space age of communication to begin. On July 10 of that year, Telstar 1 developed by the American Telephone and Telegraph Company (AT&T), was the world's first active communications satellite to be launched. Shortly after the launch the white spherical spacecraft with an exterior covered with solar cells, linked the U.S. and France thus facilitating the first transatlantic television transmission. Unfortunately, Telstar wouldn't remain in operation for long. In November of the same year, as it launched, radiation from the Van Allen belt fried its electronics. This led to its deactivation in February of 1963.

Satellites go global: Other countries enter the space race

The U.S. and Russia weren't the only countries to get involved in the new space age. France and Japan would be the first two countries to launch satellites outside of the superpowers in 1965 and 1970, respectively. Also in 1970, China would become the fifth country to launch a satellite when it blasted Dongfanghong 1 into Earth orbit on its Long March rocket. The United Kingdom launched its first satellite, the Prospero, in 1971 from Woomera, Australia, atop a Black Arrow rocket.

International collaboration became a key part of satellite launches in 1979 when the European Space Agency (ESA) launched Ariane-1 carrying two telecommunications satellites. Without this international collaboration, it would have been impossible to launch what is arguably humanity's most ambitious satellite  —  the International Space Station (ISS). The ISS  —  a collaboration involving Russia, the USA, the European Union, Japan, and Canada  —  would launch in 1998. It remains in operation to this day.

How to Balance the Screen Time, Tech Use and Mental Health of Children and Adults

 

As a business owner and parent, I understand the struggle of balancing the benefits of technology with its potential negative impact on mental health. In this digital age, finding the right balance between screen time and other activities is crucial for the well-being of both children and adults. Join me on this journey as we explore how to prioritize mental health while navigating the digital landscape.

The balancing act

When it comes to digital devices, finding the sweet spot between too much and too little is vital for a healthy relationship with technology. Screen time can be beneficial for children's mental development, allowing them to learn new skills, connect with others and discover new interests. However, too much screen time can have negative consequences, such as sleep disruption, decreased physical activity, and a higher risk of depression and anxiety.

Sleep vs. screen time: The eternal struggle

A good night's sleep is essential for children's mental health, but bedtime tantrums are real, especially when a digital device is lying around. The blue light from screens can deceive their brains into thinking it's daytime, making it harder for them to drift off to dreamland. To avoid tossing and turning and the dreaded cranky mornings, establish a screen-free bedtime routine with calming activities such as reading, puzzles or meditation. And who knows? You might just score some much-needed peace and quiet...maybe.According to the National Sleep Foundation, children between the ages of 6 and 13 need between 9 and 11 hours of sleep per night. Lack of sleep can affect children's cognitive abilities, behavior, and emotional well-being. Therefore, it's important to establish healthy sleep habits that include a screen-free bedtime routine

The holy grail: Quality time with your kiddos

In this digital era, the importance of quality time with your children cannot be overstated. By setting aside regular screen-free family time, you'll strengthen your bond and support their mental health. Whether it's a family game night, a shared meal or a weekend escapade, these moments of connection are invaluable in creating a nurturing and supportive environment for your offspring.

Research has shown that quality family time can lead to better mental health outcomes for children, including improved social skills, self-esteem, and resilience. It can also help reduce the negative effects of screen time and strengthen the parent-child relationship.

The role of parents

As parents, it's our responsibility to model healthy screen habits and establish guidelines for our children's digital use. This includes setting limits on screen time, monitoring their online activities, and promoting the use of technology for educational and creative purposes.

It's also important to have open and honest conversations with our children about the potential negative effects of screen time on mental health and the importance of finding balance in all aspects of life. By working together as a family, we can create a positive relationship with technology while prioritizing mental health and well-being.

Navigating the digital landscape while prioritizing mental health for children and adults can be thrilling and challenging. By embracing the quirks and complexities of life in a tech-saturated world while remaining vigilant about promoting healthy screen habits for all ages, we can raise resilient beings who can thrive both online and offline. As parents and individuals in this new tech epoch, we're doing our best. So let's cut ourselves some slack and continue on this journey with a focus on creating a positive relationship with technology. By prioritizing mental health and well-being, we can ensure a bright and healthy future for ourselves and our children (and more sleep?...maybe, maybe not).

Screen time 2.0: Mindfulness in the digital world

Not all screen time is equal. While aimlessly scrolling social media or binge-watching YouTube videos might not be a mental health booster, engaging in educational, creative or interactive content can yield positive results. Prod your kids to use their screen time wisely by exploring educational apps, acquiring new skills or joining virtual clubs and organizations. Mindfulness is the secret sauce that makes a world of difference.

The social scene: Fostering connections in the digital age

Technology is a double-edged sword - while it allows our kids to connect with friends and family near and far, it can also inadvertently lead to feelings of loneliness and isolation. A study published in the Journal of Social and Clinical Psychology found that people who spend more time on social media experience higher levels of anxiety and depression.

To combat the negative effects of social media, encourage your children to maintain in-person connections and engage in group activities to boost their mental well-being. By finding a balance between online and offline social interactions, you'll help them forge strong relationships and cultivate a sense of belonging. You can also set boundaries around screen time, such as limiting the use of devices during meal times or family outings.

The Impact Of Privacy Regulations On Digital Marketing

The Impact Of Privacy Regulations On Digital Marketing

As digital marketers, our goal is to create personalized experiences for customers while respecting their privacy and data. However, with the rise of privacy regulations such as GDPR (General Data Protection Regulation) and CCPA (California Consume)r Privacy Act, navigating the world of digital marketing has become more complex than ever before. These regulations have had a significant impact on digital marketing, particularly when it comes to data collection and usage of that data. This has led to some challenges for digital marketers, which I'll dig into below.

Increased transparency

Organizations are now required to be more transparent about their data collection and use practices. This means digital marketers must be clearer about what data they are collecting, how they are using it and who they are sharing it with. A simple way to increase transparency is to have dedicated pages on your website highlighting how you plan on using customer data. You can also inform customers via email how their data is being used. Giving them an opt-out option via email is always helpful as well if they do not agree with your data processing and collection methods.

Limitations on data collection

GDPR and CCPA place limitations on the types of data that organizations can collect and use. For example, organizations must have a valid legal basis for processing personal data, such as explicit consent from the individual. In recent years, because of data protection regulations, we've seen a rise in the double opt-in for email collection, where users must opt in twice before receiving emails from a brand. We've also seen more transparency around data privacy breaches, where consumers who are impacted are notified more quickly. Also, there are much stricter data privacy and compliance structures in place for keeping the financial data of customers stored. All of these rules play into trying to create a more efficient data privacy ecosystem.

Opt-in requirements

Regulations require organizations to obtain explicit opt-in consent from individuals before collecting or using their data. Digital marketers must be more proactive in obtaining consent from their customers and must make it easy for them to opt out if they choose to do so. You may notice that nowadays, a lot of companies have an "accept all cookies" pop-up button that allows you to also customize the cookie/data collection process when you visit a website. You can now start taking meaningful strides in how your data is used and what type of data you are providing to different online companies. IOS 14 had a huge impact in this space, which allows you to opt in to share data with any given app. Although this hurt Meta's bottom-line revenue from advertising, this was a huge step in positive data privacy standards that Apple helped create.

Data access and deletion requests

GDPR and CCPA give individuals the right to access their personal data and request that it be deleted. Digital marketers must be prepared to handle these types of requests and must have systems in place to quickly and effectively respond to them. If a customer does not wish to receive any more email updates, for example, you must include an "unsubscribe" button on every single customer email blast. If a customer does not want their cookies/data collected while visiting your website, you must give them the option to prohibit this data collection without their explicit consent.

Update your privacy policy

Make sure to outline your data collection and usage practices clearly, and keep your privacy policy up to date. This will help ensure that individuals are fully informed about how their data is being used.

Implement data access and deletion procedures

Make sure you have procedures in place to quickly and effectively respond to data access and deletion requests. This may require changes to your data management systems and processes.

In a nutshell, privacy regulations have had a significant impact on digital marketing. While navigating them can be challenging, it's important for digital marketers to prioritize privacy and data protection in their practices.
