Washington, March 26, 2017: NASA said its Juno spacecraft will make its fifth flyby over Jupiter’s mysterious cloud tops on Monday.

At the time of closest approach, Juno will be about 4,400 km above the planet’s cloud tops, moving at a speed of about 57.8 km per second relative to the gas-giant planet.

All of Juno’s eight science instruments will be on and collecting data during the flyby.

“This will be our fourth science pass — the fifth close flyby of Jupiter of the mission — and we are excited to see what new discoveries Juno will reveal,” said Scott Bolton, Principal Investigator of Juno from the Southwest Research Institute in San Antonio, US.

“Every time we get near Jupiter’s cloud tops, we learn new insights that help us understand this amazing giant planet,” Bolton said in a statement.

Launched on August 5, 2011, from Cape Canaveral, Florida, Juno arrived in orbit around Jupiter on July 4, 2016.

During its mission of exploration, Juno soars low over the planet’s cloud tops.

During these flybys, Juno probes beneath the obscuring cloud cover of Jupiter and studying its auroras to learn more about the planet’s origins, structure, atmosphere and magnetosphere.

The Juno science team continues to analyse returns from previous flybys. Scientists have discovered that Jupiter’s magnetic fields are more complicated than originally thought, and that the belts and zones that give the planet’s cloud tops their distinctive look extend deep into the its interior.

Observations of the energetic particles that create the incandescent auroras suggest a complicated current system involving charged material lofted from volcanoes on Jupiter’s moon Io.

Peer-reviewed papers with more in-depth science results from Juno’s first flybys are expected to be published within the next few months, NASA said. (IANS)

US Senators Want NASA To Extend The ISS Life Until At Least 2028

The aim was to save mony so that more resources could invested into deep space exploration of the Moon and eventually Mars.

NASA should extend the life of the International Space Station (ISS) until at least 2028, two US Senators said in a hearing to examine the future of the orbiting laboratory.

Senator Ted Cruz of Texas who is the Chairman of the Subcommittee on Space, Science, and Competitiveness convened the hearing on Wednesday, which was the first in a series of two hearings to examine the role of the space station.

In its 2019 budget request, the Donald Trump administration proposed ending direct government funding for the ISS by 2025, Florida Today, part of the USA Today network, reported on Wednesday.

“We’ve got this platform up there (worth) north of $100 billion, and it’s there,” Senator Bill Nelson of Florida, ranking member on the Subcommittee on Space, Science and Competitiveness, was quoted as saying.

“Abandoning this incredible orbiting laboratory where they are doing research, when we are on the cusp of a new era of space exploration, would be irresponsible at best and probably disastrous,” Nelson added.

The NASA Transition Authorization Act of 2017 directed NASA to develop a plan to transition ISS from the current regime that relies heavily on NASA sponsorship to a regime where NASA could be one of many customers of a low-Earth orbit (LEO) non-governmental human space flight enterprise.

The aim was to save mony so that more resources could invested into deep space exploration of the Moon and eventually Mars.

The space agency’s internal watchdog on Wednesday, however, said that private companies are unlikely to take on the more than $1 billion annual cost to run the International Space Station by 2025 as NASA hopes.

The report from NASA Inspector General provided a closing argument against the Trump administration’s proposal to privatise or abandon the orbiting laboratory so soon, the US senators said, according to the Florida Today report.

“The defence rests,” quipped Senator Cruz of Texas. (IANS)
