Jupiter’s ocean moon Europa is probably covered with blades of ice up to 15 meters tall in its equatorial regions, making alien life search difficult, NASA researchers have found.

The potentially life-supporting Europa has been studied by NASA, whose work has become more difficult due to the ice towers, Xinhua news agency reported.

“Clearly, the paper suggests very strongly that the tropics of Europa are going to be spiky, and it would be unwise to plan to land there without a specially adapted lander,” said Dan Hobley, lead author of the study and a lecturer in the School of Earth and Ocean Sciences at Cardiff University.

Jagged ice towers could also be found on Earth, especially in high, dry and cold tropical regions like the Chilean Andes. These ice towers are named “penitentes”, Spanish for “penitent”, because they often look like people kneeling in penance.

Scientists found that penitentes on Europa could be up to 15 meters tall, spaced about seven meters apart, while on Earth their height usually ranges from one to five meters.

“The Europa penitentes grow much slower than the Earth examples, but on Earth they might be restricted to a season or maybe two until they melt in summer or get covered in more snow, but on Europa, they are sat out in the sun growing for 50 million years,” Hobley explained.

NASA plans to launch a mission called Europa Clipper in the 2020s.

At a cost of $2 billion, the mission will “perform repeated close flybys of the icy moon from a long, looping orbit around Jupiter”, assess the possible landing site on Europa and try to seek out signs of life on the moon. (IANS)

Trump Increases NASA Spending by $1.6 Billion With Goal of Returning to Moon

"I am updating my budget to include an additional $1.6 billion so that we can return to Space in a BIG WAY!"

The Trump administration asked Congress on Monday to increase NASA spending next year by an extra $1.6 billion to accommodate the accelerated goal of returning Americans to the surface of the moon by 2024.

The increased funding request, announced by President Donald Trump on Twitter, comes nearly two months after Vice President Mike Pence declared the objective of shortening by four years NASA’s timeline for putting astronauts back on the moon for the first time since 1972.

The proposed increase would bring NASA’s total spending level for the 2020 fiscal year to $22.6 billion. The bulk of the increase is earmarked for research and development for a human lunar landing system, according to a summary provided by NASA.

“Under my Administration, we are restoring @NASA to greatness and we are going back to the Moon, then Mars,” Trump tweeted late on Monday. “I am updating my budget to include an additional $1.6 billion so that we can return to Space in a BIG WAY!” NASA had previously aimed to return crewed spacecraft to the lunar surface by the year 2028, after first putting a “Gateway” station into orbit around the moon by 2024.

The newly accelerated goal – an endeavor likely to cost tens of billions of dollars – comes as NASA has struggled with the help of private partners to resume human space missions from U.S. soil for the first time since the shuttle program ended in 2011.

The U.S. Apollo program, NASA’s forerunner to the effort at returning humans to Earth’s natural satellite, tallied six manned missions to the moon from 1969 to 1972. So far, only two other nations have conducted controlled “soft” landings on the moon – the former Soviet Union and China. But those were with unmanned robot vehicles. (VOA)
