New York, Feb 25, 2017: Scientists have recovered a lost football-field-sized balloon with a telescope hanging beneath it from Antarctica after a year of its flight.

According to the US space agency NASA, the balloon floated 39 kms above the Antarctic continent for 12 days in January 2016 until scientists sent the pre-planned command to cut the balloon.

The telescope parachuted to the ground in the Queen Maud region of Antarctica where it remained on the ice for an entire year.

“The scientists did quickly recover the data vaults from the NASA-funded mission, called GRIPS (Gamma-Ray Imager/Polarimeter for Solar flares), but due to incoming winter weather they had to leave the remaining instruments on the ice and schedule a recovery effort for the following year,” NASAsaid in a statement on Saturday.

The instruments were finally recovered in January this year when it was warm and safe enough for scientists to go there.

“Despite sitting on the ice for a year, no snow had made it into the electronics. The cryostat instrument, which houses the GRIPS detectors, seemed in great condition, and we’re hoping to use some of the instruments again,” said Hazel Bain, a solar physicist on the GRIPS team.

GRIPS is a helium balloon-borne telescope designed to study high-energy particles generated by solar flares and help scientists better understand what causes these giant eruptions on the sun, which can send energy toward our planet and shape the very nature of near-Earth space.

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
