Parker Solar Probe launched on seven-year odyssey: NASA
Miami, Aug 12 : NASA on Sunday said it had launched Parker Solar Probe, the US space agency's historic small car-sized probe, on its seven-year space odyssey that will take it gradually closer to the Sun at 3.8 million miles.
The spacecraft, launched from Cape Canaveral Air Force Station in Florida, will transmit its first scientific observations in December, beginning a revolution in our understanding of the star that makes life on Earth possible.
The mission's findings will help researchers improve their forecasts of space weather events, which have the potential to damage satellites and harm astronauts in orbit, disrupt radio communications and, at their most severe, overwhelm power grids.
"#ParkerSolarProbe lifted off from Space Launch Complex 37 at Cape Canaveral Air Force Station in Florida at 3.31 a.m. EDT (European Daylight Time) aboard a @ulalaunch #DeltaIVHeavy!," the US-based space agency tweeted.
At 5.33 a.m., the mission operations manager reported that the spacecraft was operating normally.
The launch was initially planned for Saturday morning.
Over the next two months, Parker Solar Probe will fly towards Venus, performing its first Venus gravity assist in early October -- a manoeuvre a bit like a handbrake turn -- that whips the spacecraft around the planet, using Venus's gravity to trim the spacecraft's orbit tighter around the Sun.
"This mission truly marks the humanity's first visit to a star that will have implications not just here on Earth, but how we better understand our universe," Thomas Zurbuchen, Associate Administrator of NASA's Science Mission Directorate, said in a statement.
This first flyby will place Parker Solar Probe in position in early November to fly as close as 15 million miles from the Sun -- within the blazing solar atmosphere, known as the corona -- closer than anything made by humanity has ever gone before.
Throughout its seven-year mission, Parker Solar Probe will make six more Venus flybys and 24 total passes by the Sun, journeying steadily closer to the Sun until it makes its closest approach at 3.8 million miles.
Parker Solar Probe will set its sights on the corona to solve long-standing, foundational mysteries of Sun, the US-based space agency said.
The probe is named after Eugene Parker, a solar physicist, who in 1958 first predicted the existence of the solar wind, a stream of charged particles and magnetic fields that flow continuously from the sun.

Taj Mahal top earning ASI monument through ticket sales from FY19-20 to FY23-24: Govt
New Delhi, Apr 3 (PTI): The iconic Taj Mahal in Agra earned the "highest income" through the sale of tickets among the ASI-protected monuments from FY19-20 to FY23-24, according to data shared by the government.
Union Culture Minister Gajendra Singh Shekhawat shared the data in a written response to a query in Rajya Sabha.
He was asked the amount that the Archaeological Survey of India (ASI) has received from selling entry tickets to various monuments in the last five years, year-wise and monument-wise; and the monuments that have received the highest income through selling entry tickets in the last five years.
In his response, the minister shared the data in a tabular form for cycles of financial years ranging from FY19-20 to FY23-24.
According to the data, Taj Mahal earned the top slot for all five years.
The Mughal-era architectural wonder was commissioned by Emperor Shah Jehan in the 17th century and it is considered one of the most beautiful buildings in the world.
In FY19-20, the Agra Fort in Agra and Qutub Minar in Delhi were in the second and third positions.
In FY20-21, the Group of Monuments Mamallapuram in Tamil Nadu and Sun Temple, Konark were in the second and third positions. In FY23-24, Qutub Minar and Red Fort of Delhi were in the second and third positions.
