NASA’s Parker Solar Probe, which is humanity’s first mission to the Sun, has cleared the final procedures ahead of its launch on August 11.

“NASA’s Parker Solar Probe has cleared the final procedures in the clean room before its move to the launch pad, where it will be integrated onto its launch vehicle, a United Launch Alliance Delta IV Heavy,” the space agency said in a statement.

The mission termed as historic “will revolutionize our understanding of the Sun, where changing conditions can propagate out into the solar system, affecting Earth and other worlds”, it added.

The 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.

In addition to using the largest operational launch vehicle, the Delta IV Heavy, the Parker Solar Probe will use a third stage rocket to gain the speed needed to reach the Sun, which takes 55 times more energy than reaching Mars.

The spacecraft will travel directly into the Sun’s atmosphere, about 4 million miles from its surface and more than seven times closer than any spacecraft has come before, due to its innovative Thermal Protection System.

The mission will perform the closest-ever observations of a star when it travels through the Sun’s outer atmosphere, called the corona.

The mission will rely on measurements and imaging to revolutionize our understanding of the corona and how processes there ultimately affect near-Earth space, NASA said. (IANS)

Anticipated Problems That May Effect NASA’s Mars Mission

According to results from the first eight analog space crews, presented at the American Association for the Advancement of Science (AAAS) annual meeting in Washington, D.C., the astronauts are able to successfully complete tasks between 20 and 60 per cent of the time.

Researchers are developing a predictive model to help NASA anticipate conflicts and communication breakdowns among crew members and tick off problems that may make or break the Mission to Mars.

NASA has formalised plans to send a manned mission to Mars, a journey that could involve 250 million miles of travel on a small spacecraft.

To understand the psychological demands of this Mars journey, Northwestern University has charted a multi-phase study conducted in two analog environments — HERA in the Johnson Space Center in Houston and the SIRIUS Mission in the NEK analog located in the Institute for Bio-Medical Problems (IBMP) in Russia.

The varsity will study the behaviour of analog astronaut crews on mock missions, complete with isolation, sleep deprivation, specially designed tasks and mission control, which mimics real space travel with delayed communication.

“Astronauts are super humans. They are people who are incredibly physically fit and extremely smart,” said Leslie DeChurch, Professor at Northwestern.

“We’re taking an already state-of-the-art crew selection system and making it even better by finding the values, traits and other characteristics that will allow NASA to compose crews that will get along,” DeChurch added.

HERA’s capsule simulator houses astronauts for up to 45 days — a mock mission control outside the capsule — that augments the realism with sound effects, vibrations and communication delays.

The next phase of the research, which began on February 15, involves using the model to predict breakdowns and problems a new HERA crew will experience and making changes to “who works with whom, on what, and when”.

The experiment on the SIRIUS analog in Moscow, will begin on March 15, where four Russians and two Americans, will undertake a 120-day fictional mission around the moon, including a moon landing operation. (IANS)
