NASA’s Juno spacecraft detects “Monster” Cyclones on Jupiter’s Surface

Along with the fierce storms, the researchers saw a huge river of ammonia gas extending from Jupiter's deep atmosphere down to its interior

US, May 26, 2017: Scientists looking at the first pictures of the planet Jupiter sent by the NASA probe Juno were shocked at what they saw: monster cyclones, hundreds of kilometers wide, tearing across the planet’s north and south poles.

The scientists said the poles are nothing like the planet’s familiar placid and colorful equatorial region.

This image made available by NASA on May 25, 2017, and made from data captured by the Juno spacecraft shows Jupiter's south pole. The oval features are cyclones, up to 600 miles (1,000 kilometers) in diameter.

“That’s the Jupiter we’ve all known and grown to love,” Scott Bolton of the Southwest Research Institute, an applied research and development organization in San Antonio, Texas, said in an article released Thursday in the journal Science. “And when you look from the pole, it looks totally different. … I don’t think anybody would have guessed this is Jupiter.”

Bolton called the findings “Earth-shattering. Or, should I say, Jupiter-shattering.

Along with the fierce storms, the researchers saw a huge river of ammonia gas extending from Jupiter’s deep atmosphere down to its interior. They said they thought the ammonia might be part of what’s causing the huge storms.

NASA had launched Juno in 2011, and it reached Jupiter’s orbit last year. The scientists said that Juno’s next fly-by would come in July, when it will take pictures of the planet’s trademark Great Red Spot — a huge, hurricane-like storm that experts say has been raging for hundreds of years. (VOA)

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.

Those on the inside undergo sleep deprivation and try to perform tasks. The researchers collect moment-to-moment metrics about individual performance, moods, psychosocial adaptation and more.

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)
