NASA to test robot in Antarctica for extra-terrestrial exploration

Sydney – The United States’ National Aeronautics and Space Administration (NASA) will test an under-ice robot during Antarctica’s summer with a view to using it to look for extra-terrestrial life on one of Jupiter’s moons in 2025.

The one-meter (three feet) long robotic rover is buoyant and has two wheels to operate on the under-side of ice, the Australian Antarctic Division (AAD) said in a statement.

“The rover is unique in that it uses buoyancy to stick to the underside of the ice and move upside-down using wheels, so it can get up close to the ice-water interface for sensitive measurements,” NASA Jet Propulsion Laboratory engineer Andy Klesh said.

The robot has already been deployed in Alaska and the Arctic and will be tested in Antarctica at Australia’s Casey research station for three weeks.

Much like a submarine, the rover can remain in one spot for long periods of time without expending energy.

In 2025, NASA plans to send a mission to Jupiter’s icy moon, Europa, believed to be one of the likeliest places in the solar system to find alien life.

“NASA’s Galileo mission to Jupiter in the late 1990s investigated the planet’s moons including Europa. They found strong evidence there was a salty ocean beneath Europa’s thick icy crust, as well as a rocky sea floor,” NASA scientist Kevin Hand said.

“This salty ocean could hold more than twice as much water as Earth and have all the right ingredients to support simple life organisms,” he added.

NASA would have to drill through between 10 to 20 kilometers (6-12 miles) of icy crust before it can reach the water, a matter that has not yet been resolved.

“We don’t really know how to manage this yet, but it’s likely we will have to drop transmission pucks every 100 meters to carry signals from the rover up to a surface base station, before the information is beamed back to Earth via satellite,” Klesh explained. EFE-EPA

Lunar Loo Challenge: Design the new toilet for NASA

Aileen Cerrudo   •   June 30, 2020

The National Aeronautics and Space Administration (NASA) has launched the Lunar Loo Challenge to call on the global community to design compact toilets that can operate in both microgravity and lunar gravity.

The new design may be adapted for use in the Artemis lunar landers as NASA prepares to return to the moon by 2024.

“Although space toilets already exist and are in use (at the International Space Station, for example), they are designed for microgravity only. NASA is looking for a next-generation device that is smaller, more efficient, and capable of working in both microgravity and lunar gravity,” according to NASA.

NASA’s Lunar Loo challenge has a total prize purse of $35,000 that will be shared among the teams submitting the top three designs in the Technical category.

NASA is also encouraging the next generation of space explorers, engineers, and scientists, to also design new concepts through the Junior Category. For all the details, visit https://www.herox.com/LunarLoo. AAC

Stargazers watch peak of Lyrid meteor shower

Aileen Cerrudo   •   April 23, 2020

People looked up to skies on Wednesday (April 22) to witness the peak of the Lyrid meteor shower.

According to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA), Lyrids are bright and fast meteors that are active from April 16 to 25 every year.

Several stargazers were able to witness this spectacle while others just enjoyed watching the stars.

“The Lyrid meteor shower has been observed for more than 2,600 years. Chinese records show that ‘stars fell like rain’ during the meteor shower of 687 B.C.,” according to PAGASA.

However, they also reported that in recent times, the Lyrids have generally been weak.

“The shower typically generates a dozen meteors per hour under optimal conditions with a brief maximum that lasts for less than a day,” PAGASA stated. AAC

LOOK: NASA’s 50-year observation of Earth from space

Aileen Cerrudo   •   April 23, 2020

The National Aeronautics and Space Administration (NASA) released a compilation of images of their observations of the Earth in a span of 50 years.

“From the Apollo 8 “Earthrise” image to a growing fleet of satellites, these missions enhanced our understanding of our home planet,” according to NASA’s Twitter post.

This is in celebration of the 50th anniversary of Earth Day.

The video showed bits of what earth looks like from space. The video also covered Earth’s changes over the years. AAC
