Space station crew will experience New Year’s Eve 16 times, says NASA

The six astronauts and cosmonauts will go into the last weekend of 2017 with light duty and family conferences before taking the New Year’s Day off.

As the astronauts aboard the International Space Station (ISS) orbit Earth once every 90 minutes, they will experience New Year’s Eve 16 times, NASA pointed out. That is 16 sunrise and sunsets 402.3 km above Earth, the US space agency said in a blog post on Thursday. The six astronauts and cosmonauts will go into the last weekend of 2017 with light duty and family conferences before taking the New Year’s Day off.

The current six crew members on the orbital laboratory comprise three US astronauts, two Russian cosmonauts and a Japanese astronaut. Ahead of the New Year, the astronauts are conducting life science studies to help mission doctors keep astronauts healthier and stronger while living in outer space.

Japanese astronaut Norishige Kanai took his turn on the exercise bike on Thursday for a study researching physical exertion in space. Doctors measure the astronauts breathing and other parameters during exercise to ensure they have the strength to perform strenuous activities such as spacewalks and even emergency procedures.

Flight Engineer Scott Tingle of NASA was harvesting plants for the Advanced Plants Experiment-05 (APEX) and stowing the botany samples in a science freezer for further analysis, the blog post said.

Scientists are exploring how plants respond to microgravity and observing molecular and genetic changes. The two other NASA astronauts living and working aboard the space station are Vande Hei and Joe Acaba. Anton Shkaplerov and Alexander Misurkin of the Russian space agency Roscosmos are the other two other crew members.

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
