NASA Will Soon Touch The Sun


It did not even start, and NASA’s mission to fly to the sun was delayed yesterday by a technical problem.

Early in the morning they started the countdown and after 5 seconds into it the Parker Solar Probe remained with the Delta IV rocket on its pad.

United Launch Alliance, the rocket maker, suggested that a new trial will be made today unless the helium-pressure problem is fixed. “Hold, hold, hold,” said a launch controller after the gaseous helium system’s red pressure alarm went off.

If the Parker probe takes off, it will be the first rocket to be that close to the sun. Rocket issues keep the $1.5 billion mission aside, and it is a week late.

The failed launch had a lot of public in the middle of the night including the astrophysicist from the University of Chicago after whom the rocket was named. He is the predictor of the existence of solar wind, Eugene Parker. He made that prediction when he was 31 years old, and now at the age of 91, he wants to see the mission complete.


The spacecraft’s heat shield can withstand extreme radiation and 1370C even though it is just 11cm thick. The guard measures 2.4m and would keep the science instrument in a shade of 27C.


Before reaching the sun, the spacecraft will run past Venus whiches gravity will be used to get as close as possible to the sun. Along with other procedures, the mission will take at least seven years.


The first spacecraft with the same mission as Parker, Helios 2, was 43 million km close to the sun in 1976. The current rocket is expected to pass that limit.

The speed of the spacecraft will also be faster than ever with a speed of 690km/h.
