A moon, meteor, or computer that orbits a planet or star is known as a satellite. As it orbits the sun, the Earth, for example, is a satellite. Since it orbits Earth, the moon is indeed a satellite. The term “satellite” usually refers to a system launched into space and orbits Earth or another celestial body. Atomic satellites include the Earth and the Moon. Thousands of artificial satellites, also known as human-made satellites, orbit the Earth. Any people take photographs of the Earth to aid meteorologists in forecasting storms and tracking hurricanes. Others photograph other planets, the stars, black holes, dark matter, and distant galaxies that aid scientists in understanding the solar system and the cosmos in general. Some satellites are mostly used for communications, such as broadcasting television transmissions and making phone calls worldwide.
The Global Positioning System, or GPS, is made up of more than 20 satellites. These satellites will assist you in determining your precise position if you have a GPS receiver. NASA has launched hundreds of spacecrafts into space since the Explorer 1 satellite in 1958. Explorer 1 was the United States’ first human-made spacecraft. A cosmic ray monitor was the main instrument onboard, and it measured high-energy particles in space. The first satellite image of Earth was launched by NASA’s Explorer 6 in 1959. TIROS-1 was the first satellite to relay Earth’s television view from orbit, having launched in 1960. These photographs lacked a great deal of detail. They did, though, show that satellites had the potential to change people’s views of the Earth and space.
However, India’s first space launch flight of the year, PSLV-C51, will not launch its first non-governmental Earth-imaging satellite as a result of the technical problems, with Bengaluru-centered startup Pixxel withdrawing its satellite. The launching was scheduled to happen on 28th February. In a statement, Pixxel said that they had made a decision not to continue with the launching process due to specific software issues that emerged during testing. He also added that the company had made a decision to push the deployment by two weeks to re-evaluate the software.
Moreover, Pixxel also added that given the time and commitment that they went into producing the satellite, it didn’t make sense to hurry a satellite to deploy in which they don’t have full trust at that time. In the 2020 edition of The Economic Times Startup Awards, Pixxel was one of the Best on Campus category’s finalists. The company came in second place for the prize, which Bellatrix won, a space technology company that makes electric propulsion engines for satellites.
