TEHRAN, August 11 -US space agency NASA postponed the launch of the Parker Solar Probe on Saturday - the start of a years-long mission to study the sun up close for the first time ever.
TEHRAN, Young Journalists Club (YJC) -US space agency NASA postponed the launch of the Parker Solar Probe on Saturday - the start of a years-long mission to study the sun up close for the first time ever.
Technical issues caused the launch to be interrupted twice, which eventually led to the launch window being missed.
NASA will attempt a new launch from Cape Canaveral Air Force Station in Florida using a Delta IV Heavy, the world's second-most powerful rocket currently in use, on Sunday, NASA said.
The probe - which will be the fastest spacecraft ever once it reaches top speed - will gather data on the inner workings of the sun on its flybys, which will happen in 2023.
When the spacecraft reaches top speed, it will fly 700,000 kilometres per hour - fast enough to travel from London to Berlin in about three seconds.
"Parker Solar Probe will travel through the sun's atmosphere, closer to the surface than any spacecraft before it, facing brutal heat and radiation conditions, and ultimately providing humanity with the closest-ever observations of a star," the US space agency said in a statement.
The spacecraft will first fly around Earth's neighbouring planet Venus and use that planet's gravity to build up speed and fly towards the sun.
At its closest flyby, the probe will be just 6.13 million kilometres from the sun.
The distance between the sun and Earth is almost 150-million kilometres.
