The Solar Orbiter spacecraft, built for NASA and the European Space Agency, lifts off from pad 41.
The US-European Solar Orbiter probe launched Sunday night from Florida on a voyage to deepen our understanding of the Sun and how it shapes the space weather that impacts technology back on Earth.
The mission, a collaboration between ESA (the European Space Agency) and NASA, successfully blasted off from the Kennedy Space Center in Cape Canaveral at 11:03pm (0403 GMT Monday) and could last up to nine years or more.
At 12:24am Monday (0524 GMT) the European Space Operations Centre in Darmstadt, Germany, received a signal from the spacecraft indicating that its solar panels had successfully deployed.
Space Orbiter is expected to provide unprecedented insights into the Sun's atmosphere, its winds and its magnetic fields, including how it shapes the heliosphere, the vast swath of space that encompasses our system.
Ten state-of-the-art instruments on board will record myriad observations to help scientists unlock clues about what drives solar winds and flares.
These emit billions of highly charged particles that impact the Earth, producing the spectacular Northern Lights. But they can also disrupt radar systems, radio networks and even, though rarely, render satellites useless.
The largest solar storm on record hit North America in September 1859, knocking out much of the continent's telegraph network and bathing the skies in an aurora viewable as far away as the Caribbean.
Titanium heat shield
At its closest approach, Solar Orbiter will be nearer to the Sun than Mercury, a mere 42 million kilometers (26 million miles) away.
With a custom-designed titanium heat shield, it is built to withstand temperatures as high as 500 Celsius (930 Fahrenheit). Its heat-resistant structure is coated in a thin, black layer of calcium phosphate, a charcoal-like powder that is similar to pigments used in prehistoric cave paintings.
All but one of the spacecraft's telescopes will peep out through holes in the heat shield that open and close in a carefully orchestrated dance, while other instruments will work behind the shadow of the shield.
Just like Earth, the Sun's poles are extreme regions quite different from the rest of the body. It is covered in coronal holes, cooler stretches where fast-gushing solar wind originates.
Scientists believe this region could be key to understanding what drives its magnetic activity.
Every 11 years, the Sun's poles flip: north becoming south and vice versa. Just before this event, solar activity increases, sending powerful bursts of solar material into space.
Solar Orbiter will observe the surface as it explodes and record measurements as the material goes by the spacecraft.
The only spacecraft to previously fly over the Sun's poles was another joint ESA/NASA venture, the Ulysses, launched in 1990. But it got no closer to the Sun than the Earth is.
"You can't really get much closer than Solar Orbiter is going and still look at the Sun," ESA's Muller said.
The solar system's smallest, innermost planet will resemble a tiny black dot on Monday as it passes directly between Earth and the sun. It begins at 7:35 a.m. EST.
Thai amateur astronomer Worachate Boonplod who is working on the NASA funded project Sungrazer, spotted the comet amid the solar eclipse.
The three-megawatt (MW) solar photovoltaic (PV) project is installed on the car shading at the short-term car park of the Midfield Terminal at Abu Dhabi International Airport, with 7,542 solar panels producing electricity.
The entire family are experiencing a real tragedy, particularly the girl’s mother, who daily begs doctors to solve the suffering of her daughter.
Players were shocked to find the deadly red-bellied black snake taking refuge in the hole on the second green.
The new weekly work system introduced by the Government of Sharjah has improved the productivity, satisfaction rate and happiness of the employees by almost 90 per cent.
The complainant indicated that his sister asked him to finance a vehicle with a bank and she would pay the monthly installments. He allegedly contracted with the bank to buy a 2021 model vehicle and paid Dhs200,000 in advance.
