NASA ‘s historic mission to solve the mysteries of the Sun which was launched aboard a United Launch Alliance Delta IV Heavy rocket on August 12 is operating according to plan, mission controllers have said.

As of 12 p.m. EDT on August 16, the Parker Solar Probe was 4.6 million kms from Earth, travelling at 62,764 kms per hour, and heading toward its first Venus flyby scheduled for October 3, 2018, Geoff Brown of Johns Hopkins University Applied Physics Lab, or APL, in Maryland, wrote in a NASA blog post on Friday.

The spacecraft will use Venus to slightly slow itself and adjust its trajectory for an optimal path toward the first perihelion of the Sun on November 5 this year.

“Parker Solar Probe is operating as designed, and we are progressing through our commissioning activities,” said Project Manager Andy Driesman of APL.

This solar probe is humanity’s first-ever mission into the Sun’s atmosphere, called the corona. Here it will directly explore solar processes that are key to understanding and forecasting space weather events that can impact life on Earth.

The mission has already achieved several planned milestones toward full commissioning and operations, according to the mission controllers.

On August 13, the high-gain antenna, which Parker Solar Probe uses to communicate high-rate science data to Earth, was released from locks which held it stable during launch.

Controllers have also been monitoring the spacecraft as it autonomously uses its thrusters to remove (or “dump”) momentum, which is part of the flight operations of the spacecraft.

Managing momentum helps the spacecraft remain in a stable and optimal flight profile.

There are four instrument suites on board Parker Solar Probe, which will each need to be powered and readied for science data collection.

The FIELDS investigation, which consists of the most elements, went first. It was powered up on August 13 for two activities, Brown said.

First was the opening of the clamps which held four of the five FIELDS antennas stowed during takeoff.

These antennas will be deployed roughly 30 days after launch, and they will stick out from the corners of the spacecraft’s heat shield called the Thermal Protection System and be exposed to the harsh solar environment.

Second, the spacecraft’s magnetometer boom was fully deployed. This boom contains three magnetometers and a fifth, smaller electric field antenna, all part of the FIELDS suite.

Soyuz Rocket’s Crew Say That They Trust The Rocket ,Post Previous Failure

Russian investigators said the rocket failure was caused by a sensor that was damaged during assembly.

A U.S. astronaut said on Thursday she had full confidence in the safety of the Russian-made Soyuz rocket that will blast a three-person crew into space next month in the first such launch since a rocket failure.

Russian cosmonaut Oleg Kononenko and U.S. and Canadian astronauts Anne McClain and David Saint-Jacques are due to embark for the International Space Station on Dec. 3 after a similar launch on Oct. 11 ended in an emergency landing.

Two minutes into that launch, a rocket failure forced Russian cosmonaut Alexei Ovchinin and U.S. astronaut Nick Hague to abort their mission and hurtle back to Earth in a capsule that landed in the Kazakh steppe. The two were unharmed.

Speaking at a news conference in Star City near Moscow, McClain said that occasional failures were inevitable, but that the mishap with the Soyuz-FG in October had demonstrated the reliability of its emergency safety mechanisms.

“We trust our rocket. We’re ready to fly,” she said at the conference also attended by her colleagues Kononenko and Saint-Jacques.

“A lot of people called it an accident, or an incident, or maybe want to use it as an example of it not being safe, but for us it’s exactly the opposite because our friends came home,” McClain told reporters.

Russian investigators said the rocket failure was caused by a sensor that was damaged during assembly at the Soviet era-cosmodrome at Baikonur from where McClain, Saint Jacques and Kononenko are due to launch.

Ahead of their mission, an unmanned rocket carrying cargo is due to launch on Nov 16. in what will be the first Soyuz-FG take-off from Baikonur since the mishap. (VOA)
