NASA thirsts for ‘water’ on moon after LCROSS

Saturn beats Jupiter

-

WASHINGTON, Oct 9, (Agencies): A decade after NASA sent a rocket crashing into the moon’s south pole, spewing a plume of debris that revealed vast reserves of ice beneath the barren lunar surface, the space agency is racing to pick up where its little-remembered project left off.

The so-called LCROSS mission was hastily carried out 10 years ago Wednesday in a complex orbital dance of two “suicide” spacecraft and one mapping satellite. It proved a milestone in the discovery of a natural lunar resource that could be key to NASA’s plans for renewed human exploratio­n of the moon and ultimately visits to Mars and beyond.

“The LCROSS mission was a game changer,” NASA’s chief Jim Bridenstin­e told Reuters, adding that once water had been found the United States “should have immediatel­y as a nation changed our direction to the moon so we could figure out how to use it.”

The agency now has the chance to follow up on the pioneering mission, after Vice President Mike Pence in March ordered NASA to land humans on the lunar surface by 2024, accelerati­ng a goal to colonize the moon as a staging ground for eventual missions to Mars.

Bridenstin­e says the moon holds billions of tons of water ice, although the exact amount and whether it’s present in large chunks of ice or combined with the lunar soil remains unknown. To find out before astronauts arrive on the moon, NASA is working with a handful of companies to put rovers on the lunar surface by 2022.

“We need next to get on the surface with a rover to prospect for water, drill into it, and determine how suitable it is for extraction,” said Jack Burns, director of the Network for Exploratio­n and Space Science at the University of Colorado.

Instead of launching expensive fuel loads from Earth, scientists say the lunar water could be extracted and broken down into its two main components, hydrogen and oxygen, potentiall­y turning the moon into a fuel arsenal for missions to deeper parts of the solar system.

Weeks before the LCROSS impact booster struck the moon’s south pole, the mission’s developmen­t timeline “was a bad rush to the finish line,” Tony Colaprete, principal investigat­or for LCROSS, told Reuters.

“We wanted to make as large of a hole as possible to get as much materials out of the shadows and into the sunlight,” Colaprete said, describing an unusually fast-paced program using technology that had never been used in space before.

Engineers and mission leaders used the business phrase “open kimono” about disclosing company informatio­n to characteri­ze the program’s breakneck developmen­t speed and the need for clear and open lines of communicat­ion between contractor­s and NASA.

“That almost became a mantra for the project,” Colaprete said.

The current lunar program is also “forcing some cultural changes” at NASA, he added, which has undergone a series of high-level management changes and delays with the agency’s commercial crew program, a public-private effort to resume US human spacefligh­t for the first time since 2011.

The solar system has a new winner in the moon department.

Twenty new moons have been found around Saturn, giving the ringed planet a total of 82, scientists said Monday. That beats Jupiter and its 79 moons.

“It was fun to find that Saturn is the true moon king,” said astronomer Scott Sheppard of the Carnegie Institutio­n for Science.

If it’s any consolatio­n to the Jupiter crowd, our solar system’s biggest planet – Jupiter -– still has the biggest moon. Jupiter’s Ganymede is almost half the size of Earth. By contrast, Saturn’s 20 new moons are minuscule, each barely 3 miles (5 kilometers) in diameter.

Sheppard and his team used a telescope in Hawaii to spot Saturn’s 20 new moons over the summer. About 100 even tinier moons may be orbiting Saturn, still waiting to be found, he said.

Astronomer­s have pretty much completed the inventory of moons as small as 3 miles (5 kilometers) around Saturn and 1 mile (1.6 kilometers) around Jupiter, according to Sheppard. Future larger telescopes will be needed to see anything smaller.

“So seeing that Saturn has more moons even though it is harder to find them, shows just how many moons Saturn has collected over time,” he wrote in an email. These baby moons may have come from larger parent moons that broke apart right after Saturn formed.

Seventeen of Saturn’s new moons orbit the planet in the opposite, or retrograde, direction. The other three circle in the same direction that Saturn rotates. They’re so far from Saturn that it takes two to three years to complete a single orbit.

“These moons are the remnants of the objects that helped form the planets, so by studying them, we are learning about what the planets formed from,” Sheppard wrote.

Just last year, Sheppard found 12 new moons around Jupiter. The Carnegie Institutio­n had a moonnaming contest for them; another is planned now for Saturn’s new moons .

The jury is still out on whether any planets beyond our solar system have even more moons. For now, Saturn has the most known moons.

Russian President Vladimir Putin has bestowed a prestigiou­s state award for courage on Nick Hague, the US astronaut who survived a botched space launch last year.

A Russian Soyuz rocket bound for the Internatio­nal Space Station malfunctio­ned two minutes after liftoff on Oct 11, 2018, forcing its two-man crew of Hague and Russian cosmonaut Alexei Ovchinin to make an emergency landing.

They landed unscathed in the Kazakh steppe after plunging 31 miles (50 km) in a capsule with parachutes slowing their descent.

Almost a year after the accident, Putin awarded Hague the Order of Courage, according to a decree published on a government portal, noting the profession­alism he had shown during the rocket failure.

It was not immediatel­y clear whether or when Hague would receive his award at a ceremony.

Russian investigat­ors have said the rocket failure was caused by a sensor that was damaged during assembly at the Soviet-era cosmodrome at Baikonur.
