NASA second attempt at solar probe launch

NASA second attempt at solar probe launch

The spacecraft is on an unprecedented quest that will take it straight through the wispy edges of the corona, or outer solar atmosphere, just 3.8 million (6 million kilometers) from the sun's surface.

Nasa has launched a satellite that will fly closer to the sun than any of its predecessors.

As the Parker Solar Probe probe orbits the sun, it will experience extreme radiation and temperatures as high as 1,377C - close to the melting point of steel.

The problem on Saturday had to do with the gaseous helium pressure alarm on the spacecraft, officials said early Saturday.

The unmanned spacecraft aims to get closer than any human-made object in history to the center of our solar system.

The $1.5 billion (£1.2 billion) probe, which is the size of the vehicle, will play a vital role in our understanding of the solar system.

NASA's first mission to the sun - will expolore the sun's atmosphere and its outermost atmosphere, the corona. Along the way, the spacecraft will gather data to try and solve some of the sun's great mysteries.

United will be back in action next Sunday when they travel to Falmer Stadium to take on Brighton & Hove Albion. I was fantastic spirit, and there were periods of very good football.

The Parker Solar Probe carries a lineup of instruments to study the Sun both remotely and in situ, or directly.

The spacecraft will analyse so-called "space weather", which is large eruptions of radiation from the sun which batter Earth.

More knowledge of solar wind and space storms will also help protect future deep space explorers as they journey toward the Moon or Mars. We are ready. We have the flawless payload.

"The Parker Solar Probe will help us do a much better job of predicting when a disturbance in the solar wind could hit Earth", said Justin Kasper, a project scientist and professor at the University of MI. The corona holds the answers to many of scientists' outstanding questions about the Sun's activity and processes.

During its historic journey, the probe will jet past Venus at speeds of 430,000 miles per hour, the equivalent of flying from NY to Tokyo in one minute.

It is the first space craft to be named after a living person - astrophysicist Eugene Parker, 91, who first described solar wind in 1958. "Parker Solar Probe would be just 4cm away from the Sun".

    But getting so close to the Sun requires slowing down - for which Parker will use the gravity of our neighbor planet, Venus. The current close-to-the-sun champ, NASA's former Helios 2, got within 27 million miles (43 million kilometers) in 1976.
