New York, Jan 1, 2018: US government body Defence Advanced Research Projects Agency (Darpa) and NASA have teamed up to build robotic technology that can refuel and repair friendly satellites.

“Service stations in orbit” — name given to these robotic satellites — would not only refuel satellites but also drastically improve their longevity and lifespan.

According to a report in Futurism, the robots could fix minor maintenance issues, keeping up with current orbiters as they age and sustain damage.

The agencies also hope to keep the orbit clear of debris called space pollution which is caused by broken satellites abandoned in the space.

In 2015, there were about 25,000 human-made objects larger than a human fist and roughly half a million larger than a dime orbiting Earth.

Additionally, these satellites could also face off against mechanical foes in orbit meaning it could sabotage enemy satellites in the event of war, apparently by dismantling opponents or forcing them to crash.

They could also play defence, monitoring for tampering, the report highlighted. (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
