Washington, April 12, 2017: In the first-ever live 4K video stream from space, NASA astronaut and Expedition 51 commander Peggy Whitson will take viewers more than 400 km off the Earth to the International Space Station on April 26.

The broadcast will take place at 1:30 p.m. EDT during a session at the 2017 National Association of Broadcasters (NAB) Show in Las Vegas.

“The US space agency is a pioneer in the application of advanced media — including 4K. By streaming real-time video that captures images four times the resolution of current HD technology, NASA is enhancing its ability to observe, uncover and adapt new knowledge of orbital and deep space,” the National Association of Broadcasters said in a statement.

To experience the full effect online, devices capable of viewing 4K UHD content will be required, however, lower resolution streams of the live broadcast will be available on NASA Television, NASA’s Facebook page and the agency’s website, the US space agency said.

The conversation with Whitson will take place as part of a panel called “Reaching for the Stars: Connecting to the Future with NASA and Hollywood.”

NewsGram brings to you top news around the world today.

The panel will explore how advanced imaging and cloud technologies are taking scientific research and filmmaking to the next level, and will be moderated by Carolyn Giardina, technology editor for the Hollywood Reporter.

The panel is co-produced by NAB Show, NASA, and Amazon Web Services (AWS), and will explore how advanced imaging and cloud technologies are taking scientific research and filmmaking to the next level.

During this event, Whitson will speak with Sam Blackman, CEO of AWS Elemental. (IANS)

Wintertime Ice Growth in Arctic Sea Slows Long-Term Decline: NASA

The switch will happen once the sea ice is less than 1.6 feet thick at the beginning of winter, or its concentration

While sea ice in the Arctic continues to be on the decline, a new research from the US Space agency NASA suggests that it is regrowing at faster rates during the winter than it was a few decades ago.

The findings showed that since 1958, the Arctic sea ice cover has lost on average around two-thirds of its thickness and now 70 per cent of the sea ice cap is made of seasonal ice, or ice that forms and melts within a single year.

But at the same time, that sea ice is vanishing quicker than it has ever been observed in the satellite record, it is also thickening at a faster rate during winter.

This increase in growth rate might last for decades, explained the researchers, in the paper to be published in the journal Geophysical Research Letters.

However, this does not mean that the ice cover is recovering, though. Just delaying its demise.

“This increase in the amount of sea ice growing in winter doesn’t overcome the large increase in melting we’ve observed in recent decades,” said lead author Alek Petty, a sea ice scientist at NASA’s Goddard Space Flight Center in Maryland.

“Overall, thickness is decreasing. Arctic sea ice is still very much in decline across all seasons and is projected to continue its decline over the coming decades,” she added.

To explore sea ice growth variability across the Arctic, the team used climate models and observations of sea ice thickness from the European Space Agency’s CryoSat-2 satellite.

They found that in the 1980s, when Arctic sea ice was on average 6.6 feet thick in October, about 3.3 extra feet of ice would form over the winter.

This rate of growth may continue to increase, and in the coming decades, we could also have an ice pack that would on average be only around 3.3 feet thick in October, but could experience up to five feet of ice growth over the winter.

However, by the middle of the century, the strong increases in atmospheric and oceanic temperatures will outweigh the mechanism that allows ice to regrow faster, and the Arctic sea ice cover will decline further, Petty said.

The switch will happen once the sea ice is less than 1.6 feet thick at the beginning of winter, or its concentration — the percentage of an area that is covered in sea ice — is less than 50 per cent, she noted. (IANS)
