Untuk Pertama Kali dalam Sejarah, Wahana Kita Berhasil Mepet ke Matahari

Summary

The Parker Solar Probe is a groundbreaking spacecraft designed to explore the Sun. Launched on August 12, 2018, its mission is to get closer to the Sun than any other man-made object. Using gravity assists from Venus, the probe accelerates to extreme speeds, allowing it to gather data on the Sun's corona, solar wind, and electromagnetic fields. This exploration will help scientists understand the Sun's behavior, including its effects on technology. Parker Solar Probe's innovative heat shield and advanced instruments make it possible to endure the intense solar radiation, revolutionizing our understanding of the closest star.

Takeaways

• 😀 The Delta IV Heavy rocket is one of the most advanced rockets ever made, with powerful engines designed to burn massive amounts of fuel to launch into space.
• 😀 Parker Solar Probe, launched on August 12, 2018, is the first spacecraft designed to approach the Sun closely, at a distance of 150 million km from Earth.
• 😀 The spacecraft uses gravity assists from Venus to increase its speed without consuming additional fuel, allowing it to travel faster toward the Sun.
• 😀 Parker Solar Probe enters the Sun's orbit in elliptical paths, with each orbit bringing it closer to the Sun, while its speed and energy increase.
• 😀 The probe's closest approach to the Sun, known as perihelion, occurs at high speed, but as it moves away, it gradually slows down due to the Sun's gravitational pull.
• 😀 Parker Solar Probe’s trajectory intersects Venus's orbit multiple times, gaining speed with each pass to move closer to the Sun.
• 😀 In April 2024, Parker Solar Probe will reach the closest point to the Sun, nearing the Sun’s corona, which is still 8.5 million km away.
• 😀 The Sun consists of various layers: the core, radiation zone, convection zone, photosphere, chromosphere, and corona, each with unique characteristics.
• 😀 The probe has a special heat shield made of advanced materials that can withstand temperatures up to 1,370°C, allowing it to survive extreme conditions while measuring solar phenomena.
• 😀 Parker Solar Probe is the fastest human-made object, reaching speeds of up to 700,000 km/h by 2025. This speed is nearly 0.064% of the speed of light, enabling quick travel across vast distances.

Q & A

What is the Delta for Heavy rocket, and what makes it significant?

The Delta for Heavy rocket is one of the most advanced rockets ever made by humans. It is capable of burning large amounts of fuel with its three massive engines to help propel it to great heights.

How does Parker Solar Probe reach the Sun without using excessive fuel?

The Parker Solar Probe uses gravitational assists from Venus to increase its speed without using additional fuel. By orbiting Venus, the probe gains more velocity as it is pulled into the planet's gravity, which then allows it to get closer to the Sun.

What is the purpose of Parker Solar Probe's mission?

The mission of the Parker Solar Probe is to study the Sun, specifically its outer layers, including the corona, and to gather data on solar wind, magnetic fields, and the Sun's activity. The probe aims to get closer to the Sun than any previous spacecraft.

What is the significance of Parker Solar Probe's close approach to the Sun?

The Parker Solar Probe’s close approach to the Sun provides scientists with unprecedented data about the Sun’s atmosphere, especially the corona, which has never been studied in such detail before. It allows for better understanding of solar phenomena and their effects on the solar system.

How does the orbit of the Parker Solar Probe work in relation to Venus?

The Parker Solar Probe uses Venus' gravity to adjust its orbit and increase its speed. By performing a gravity assist maneuver, the probe passes close to Venus to change its trajectory and get closer to the Sun while avoiding excessive fuel use.

What are the major layers of the Sun studied by the Parker Solar Probe?

The Parker Solar Probe studies several key layers of the Sun, including the core, radiative zone, convection zone, the photosphere, the chromosphere, and the corona. It also analyzes the solar wind and its interaction with the Sun's magnetic field.

What is the photosphere, and why is it important?

The photosphere is the Sun's outermost visible layer that emits light and heat. It is the layer we see when we look directly at the Sun (with proper protection), and it is essential because it is the source of the Sun's energy that reaches Earth.

What is the role of the solar shield on Parker Solar Probe?

The Parker Solar Probe is equipped with a solar shield that protects its instruments from the extreme heat and radiation of the Sun. The shield, made of a special material, can withstand temperatures up to 1,370°C, ensuring that the probe’s instruments remain functional.

What new discoveries have been made regarding the Sun's corona?

The Parker Solar Probe has provided new insights into the Sun’s corona. Scientists discovered that the corona is not a smooth, spherical boundary as previously thought, but instead, it is fragmented and uneven, with some areas resembling mountain ranges. The cause of this irregularity is still under study.

How fast does the Parker Solar Probe travel, and what is its ultimate goal?

The Parker Solar Probe travels at speeds of up to 700,000 kilometers per hour, which is approximately 0.064% the speed of light. Its ultimate goal is to get closer to the Sun than any spacecraft before it, while studying its corona and solar wind, to gather data for understanding solar behavior.
