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)

Scientists spot massive ice deposits on Mars

Recent observations by MRO's ground-penetrating Shallow Radar instrument revealed a buried ice layer that covers more ground than the state of New Mexico.

  • Recently, scientists have found layers of ice on the Martian land.
  • Scientists think this ice might be a useful source of water for future humans.
  • The researchers had researched 8 locations on the surface of Mars.

Scientists have unearthed thick and massive deposits of ice in some regions on Mars.

The images taken by the High-Resolution Imaging Science Experiment (HiRISE) camera aboard NASA’s Mars Reconnaissance Orbiter (MRO) showed the three-dimensional structure of massive ice deposits on Mars.

The ice sheets extend from just below the surface to a depth of 100 meters or more and appear to contain distinct layers.

It extending downward from depths as shallow as 1 to 2 meters below the surface, which could preserve a record of Mars’ past climate, the researchers noted in the journal Science.

“We expect the vertical structure of Martian ice-rich deposits to preserve a record of ice deposition and past climate,” said Colin M. Dundas, from the US Geological Survey.

“They might even be a useful source of water for future human exploration of the red planet,” Dundas added.

The researchers investigated eight locations on Mars and found thick deposits cover broad regions of the Martian mid-latitudes with a smooth mantle.

However, erosion in these regions creates scarps that expose the internal structure of the mantle.

The scarps are actively retreating because of sublimation of the exposed water ice.

The ice deposits likely originated as snowfall during Mars’ high-obliquity periods and have now compacted into massive, fractured, and layered ice.

Previous researchers have revealed that the Red Planet harbours subsurface water ice.

Recent observations by MRO’s ground-penetrating Shallow Radar instrument revealed a buried ice layer that covers more ground than the state of New Mexico.

NASA’s Phoenix lander had also dug up some ice near the Martian north pole in 2008, however, it is not clear if that is part of the big sheet. IANS
