NASA's Parker Solar Probe lifts off successfully
Miami, Aug 12 : NASA on Sunday successfully launched the Parker Solar Probe, the US space agency's historic small car-size probe to "touch the Sun," from the Cape Canaveral Air Force Station in Florida.
"3-2-1... and we have liftoff of Parker #SolarProbe atop @ULAlaunch's #DeltaIV Heavy rocket," the US-based space agency tweeted.
The launch was initially planned for Saturday morning.
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.
Nestled atop a United Launch Alliance Delta IV Heavy -- one of the world's most powerful rockets -- with a third stage added, Parker Solar Probe will blasted off toward the sun with a whopping 55 times more energy than was required to reach Mars.
Weighing just 635 kgs, it is a relatively light spacecraft, Andy Driesman, project manager for the mission at the Johns Hopkins University Applied Physics Laboratory in the US, said in an earlier statement.
Zooming through space in a highly elliptical orbit, the Parker Solar Probe will reach speeds of up to 700,000 kms per hour, setting the record for the fastest spacecraft in history.
During its nominal mission lifetime of just under seven years, the Parker Solar Probe will complete 24 orbits of the Sun -- reaching within 3.8 million miles of the Sun's surface at the closest approach.
In an orbit this close to the Sun, the real challenge is to keep the spacecraft from burning up.

Regulator DGCA eases flight duty norms for pilots amid IndiGo crisis
Mumbai (PTI): Aviation watchdog DGCA on Friday eased the flight duty norms by allowing substitution of leaves with a weekly rest period amid massive operational disruptions at IndiGo, according to sources.
As per the revised Flight Duty Time Limitations (FDTL) norms, "no leave shall be substituted for weekly rest", which means that weekly rest period and leaves are to be treated separately. The clause was part of efforts to address fatigue issues among the pilots.
Citing IndiGo flight disruptions, sources told PTI that the Directorate General of Civil Aviation (DGCA) has decided to withdraw the provision 'no leave shall be substituted for weekly rest' from the FDTL norms.

"In view of the ongoing operational disruptions and representations received from various airlines regarding the need to ensure continuity and stability of operations, it has been considered necessary to review the said provision," DGCA said in a communication dated December 5.
The gaps in planning ahead of the implementation of the revised FDTL, the second phase of which came into force from November 1, have resulted in crew shortage at IndiGo and is one of the key reasons for the current disruptions.
