NASA Claims That No Evidence of Atmosphere is Found on Ultima Thule

The New Horizons flyby of Ultima Thule could help scientists better understand what conditions were like when our Solar System formed billions of years ago

New Horizons spacecraft which explored the ancient Kuiper Belt object nicknamed Ultima Thule, earlier this week, has yielded that the distant object has no evidence of an atmosphere, NASA has said.

New Horizons completed the farthest flyby in history when it came within about 2,200 miles (3,500 kilometres) of Ultima Thule at 12.33 a.m. EST on January 1, zooming past the object at more than 32,000 miles (51,000 kilometres) per hour.

Data from NASA’s New Horizons spacecraft is yielding scientific discoveries daily.

 Besides finding no evidence of an atmosphere, the initial data analysis also found no evidence of rings or satellites larger than one mile in diameter orbiting Ultima Thule, the US space agency said in a statement on Thursday.

The colour of Ultima Thule matches the colour of similar worlds in the Kuiper Belt, as determined by telescopic measurements.

The two lobes of Ultima Thule — the first Kuiper Belt contact binary visited — are nearly identical in colour. This matches what we know about binary systems which haven’t come into contact with each other, but rather orbit around a shared point of gravity, NASA said.

“The first exploration of a small Kuiper Belt object and the most distant exploration of any world in history is now history, but almost all of the data analysis lies in the future,” said Alan Stern of the Southwest Research Institute in Boulder, Colorado.

Data transmission from New Horizons will pause for about a week while the spacecraft passes behind the Sun as seen from here on Earth. Data transmission resumes January 10, starting a 20-month download of the spacecraft’s remaining scientific treasures.

“Those of us on the science team can’t wait to begin to start digging into that treasure trove,” Stern noted.

Located 6.5 billion kilometres from Earth, Ultima Thule means “beyond the known world”.

The New Horizons flyby of Ultima Thule could help scientists better understand what conditions were like when our Solar System formed billions of years ago.

New Horizons’ extended mission also includes observations of more than two-dozen other Kuiper Belt objects, as well as measurements of the plasma, gas and dust environment of the Kuiper Belt. (IANS)

The partial shutdown of the US federal government has had a serious impact on the country’s space agency NASA and development work on most future space missions has been slowed or suspended.

However, NASA has not been totally grounded by the partial government shutdown that began on December 22, after last-minute negotiations in Congress failed to end a budget standoff.

Over 95 per cent of the space agency’s employees have been furloughed. As a result, various research projects, including the Hubble Space Telescope has been put on hold, the Space.com reported on Wednesday.

Hubble suffered a mechanical problem that only furloughed NASA employees could repair.

Many workers also gathered outside the Johnson Space Center in Houston to protest the shutdown and its deleterious effects on their lives and the nation’s space programmes.

The Telescope facilities that have so far remained open during the shutdown will soon run out of money and cease operations.

This includes the National Radio Astronomy Observatory (NRAO), a federally funded organization that operates the Atacama Large Millimeter Array (ALMA), the Green Bank Telescope and the Very Large Array (VLA), the report noted.

The partial shutdown become the longest on record after January 12, overtaking the previous record of the 21-day impasse in 1995-96 under then President Bill Clinton.

US shutdown delays space missions but NASA not grounded: Report,

President Donald Trump and the Congress have been at loggerheads over his demand to include in the budget $5.7 billion funding for building a border wall along the Mexico border. Democratic leaders have rejected his call.

NASA’s Stratospheric Observatory for Infrared Astronomy (SOFIA), also called the “flying telescope” has also ceased operations since the shutdown.

The telescope, which is mounted to the fuselage of a Boeing 747 aircraft, has not flown since the shutdown began, the report said.

However, despite the shutdown some “excepted” employees remained at work, assisting astronauts aboard the International Space Station (ISS) and other space missions, the report said.

Last week, astronauts aboard the ISS conducted a range of scientific experiments and public-outreach work. They engaged in an orbital Q&A with school kids and answered a variety of questions, from the nature of the research performed aboard the ISS to the type of training astronauts receive to whether your ears pop in space.

On January 13, a SpaceX Dragon cargo capsule departed the orbiting lab for Earth, eventually splashing down in the Pacific Ocean. The robotic Dragon brought down important scientific research and hardware for examination here on terra firma.
