THE PARKER SOLAR PROBE WILL HIT TO THE SUN. THE EARTH WILL BE OBSERVING IT AT THIS TIME

By -


Months after first touching the Sun, the Parker Solar Probe is heading back into the midst of the storm. The probe will stop by for its 11th perihelion, or closest approach to the Sun in its orbit. The flyby is critical because the probe will approach the Sun from the Earth-facing side, providing unique prospects for future trips to our solar system's biggest star.

The spacecraft will approach our star at a distance of 85,29,523 kilometres on February 25. Parker is learning more about our star with its science instruments as it approaches it closer than ever before, according to Nasa. At a speed of 3,592 kilometres per hour, the probe is rushing towards the Sun.

"Parker Solar Probe reaches the Earth-facing side of the Sun during this near encounter. Earth-bound missions and other spacecraft have the potential to provide us with multiple perspectives on solar phenomena "In a tweet, the Parker investigation team stated. Out of the 24 orbits planned for the probe around the Sun, this will be the 11th flyby, with seven gravity aids from Venus.

WHAT DOES THE PARKER SOLAR PROBE DO ON SUNDAY?

The Parker Solar Probe, named for Eugene Parker, the inventor of solar wind, will collect data on solar activity as well as investigate the mysterious corona. In 2018, the Parker Solar Probe was launched to investigate the Sun. With the start of a new solar cycle and a frenzy of activity on the Sun in recent weeks, studying it has become important to comprehending space weather.

* Tracing the flow of energy that heats and accelerates the solar corona and solar wind with the probe

* Understanding the structure and dynamics of plasma and magnetic fields at solar wind sources.

* Investigate how energetic particles are accelerated and transported.

SPACECRAFT WITH THE FASTEST HUMAN-MADE TIME

Parker Solar Probe will be speeding around the Sun at around 6,92,017 kilometres per hour at its closest approach, according to Nasa. The probe will get as near to the Sun's surface as nine solar radii in the final three of its 24 orbits around the Sun, which is nine times the Sun's radius, or roughly 61,63,787 kilometres.

The Parker Solar Probe became the first human-made device to journey into the Sun's atmosphere, known as the corona, in December of last year. The spacecraft measured particles and magnetic fields coming from the Sun during the flyby. A 4.5-inch-thick carbon-composite cover protects the spacecraft and instruments from the Sun's heat, with temperatures outside the spacecraft reaching roughly 1,377 degrees Celsius.

"While the front of the Parker Solar Probe's solar shield will experience temperatures nearing 1,400 degrees Celsius at closest approach to the Sun, the spacecraft's payload will be at room temperature, at roughly 29 degrees Celsius," Nasa added.

SPACE AGENCY SAYS CHANDRAYAAN-2 ORBITER DETECTS SOLAR PROTON EVENTS ISRO

  Mumbai: The Indian Space Research Organisation (ISRO) announced on Wednesday that the Large Area Soft X-ray Spectrometer (CLASS), a payload on board the Chandrayaan-2 Orbiter, had discovered solar proton events (SPEs), which considerably increase radiation exposure to humans in space. Coronal mass ejections (CMEs), a tremendous torrent of ionised material and magnetic fields that reach Earth a few days later, causing geomagnetic storms and lighting up the polar sky with auroras, were also observed by the sensor on January 18. According to the ISRO, such multi-point measurements helps in the understanding of propagation and its impact on various planetary systems. Solar flares are dramatic explosions that occasionally spew out energetic particles (called Solar Proton Events or SPEs) into interplanetary space when the Sun is active. The majority of these are high-energy protons that have an influence on space systems and increase radiation exposure to astronauts. According ...

  BCCI president and previous India captain Sourav Ganguly has been conceded to a city clinic in the wake of testing positive for COVID-19, the cricket board sources said on Tuesday. Ganguly is two immunized and has been voyaging broadly, participating in every expert movement. The 49-year-old was hurried to a medical clinic late on Monday night as a prudent step later his RT-PCR test brought positive back. "He was taken to Woodlands Nursing Home final evening. He has been given medicine and is as of now steady," a BCCI source, who is monitoring Ganguly's wellbeing, told PTI. Ganguly was conceded to clinic two times recently and went through crisis angioplasty subsequent to having some heart issues. His senior sibling Snehasish Ganguly had additionally tried positive for COVID early this year.
