The jig may be up for an “asteroid” that’s expected to get nabbed by Earth’s gravity and become a mini moon next month. Instead of a cosmic rock, the newly discovered object appears to be an old rocket from a failed moon-landing mission 54 years ago that’s finally making its way back home, according to NASA’s leading asteroid expert. Observations should help nail its identity.
“I’m pretty jazzed about this,” Paul Chodas told The Associated Press. “It’s been a hobby of mine to find one of these and draw such a link, and I’ve been doing it for decades now.”
Chodas speculates that asteroid 2020 SO, as it is formally known, is actually the Centaur upper rocket stage that successfully propelled NASA’s Surveyor 2 lander to the moon in 1966 before it was discarded. The lander ended up crashing into the moon after one of its thrusters failed to ignite on the way there. The rocket, meanwhile, swept past the moon and into orbit around the sun as intended junk, never to be seen again — until perhaps now.
A telescope in Hawaii last month discovered the mystery object heading our way while doing a search intended to protect our planet from doomsday rocks. The object promptly was added to the International Astronomical Union’s Minor Planet Center’s tally of asteroids and comets found in our solar system, just 5,000 shy of the 1 million mark.
The object is estimated to be roughly 26 feet based on its brightness. That’s in the ballpark of the old Centaur, which would be less than 32 feet long including its engine nozzle and 10 feet in diameter.
What caught Chodas’ attention is that its near-circular orbit around the sun is quite similar to Earth’s — unusual for an asteroid.
“Flag number one,” said Chodas, who is director of the Center for Near-Earth Object Studies at NASA’s Jet Propulsion Laboratory in Southern California.
The object is also in the same plane as Earth, not tilted above or below, another red flag. Asteroids usually zip by at odd angles. Lastly, it’s approaching Earth at 1,500 mph, slow by asteroid standards.
As the object gets closer, astronomers should be able to better chart its orbit and determine how much it’s pushed around by the radiation and thermal effects of sunlight. If it’s an old Centaur — essentially a light empty can — it will move differently than a heavy space rock less susceptible to outside forces.
That’s how astronomers normally differentiate between asteroids and space junk like abandoned rocket parts, since both appear merely as moving dots in the sky. There likely are dozens of fake asteroids out there, but their motions are too imprecise or jumbled to confirm their artificial identity, said Chodas.
Sometimes it’s the other way around.
A mystery object in 1991, for example, was determined by Chodas and others to be a regular asteroid rather than debris, even though its orbit around the sun resembled Earth’s.
Asteroid hunter Carrie Nugent of Olin College of Engineering in Needham, Massachusetts, said Chodas’ conclusion is “a good one” based on solid evidence. She’s the author of the 2017 book “Asteroid Hunters.”
“Some more data would be useful so we can know for sure,” she said in an email. “Asteroid hunters from around the world will continue to watch this object to get that data. I’m excited to see how this develops!”
Chodas predicts the object will spend about four months circling Earth once it’s captured in mid-November, before shooting back out into its own orbit around the sun next March. He doubts the object will slam into Earth — “at least not this time around.”
Hockey Twitter demands a Lunar Classic after NASA reveals moon has a lot more ice than previously believed – Russian Machine Never Breaks
NASA made a special announcement on Monday that had the hockey world buzzing.
“Several studies have showed that water on the moon surface is in its permanently shadowed craters,” Paul Hertz, director of astrophysics at NASA Headquarters, said according to CBS News. “Today, we are announcing that for the first time, water has been confirmed to be present on a sunlit surface of the moon.
It is believed that there are at least 15,000 square miles of the moon’s surface that have deposits of water ice, meaning future astronauts could live off the land.
And Hockey Twitter is hoping those future astronauts are NHL players.
The ridiculousness began early in the day when the NHL on NBC Twitter photoshopped the Blackhawks and Bruins facing off on the moon. “MOON. HOCKEY. 🌕,” they wrote. “We’re ready, @NASA!”
MOON. HOCKEY. 🌕🏒

NASA finds definitive evidence of water on moon’s surface – Global News
The moon lacks the bodies of liquid water that are a hallmark of Earth but scientists said on Monday lunar water is more widespread than previously known, with water molecules trapped within mineral grains on the surface and more water perhaps hidden in ice patches residing in permanent shadows.
While research 11 years ago indicated water was relatively widespread in small amounts on the moon, a team of scientists is now reporting the first unambiguous detection of water molecules on the lunar surface. At the same time, another team is reporting that the moon possesses roughly 15,000 square miles (40,000 square kilometers) of permanent shadows that potentially could harbor hidden pockets of water in the form of ice.
Water is a precious resource and a relatively plentiful lunar presence could prove important to future astronaut and robotic missions seeking to extract and utilize water for purposes such as a drinking supply or a fuel ingredient.
A team led by Casey Honniball of NASA’s Goddard Space Flight Center in Maryland detected molecular water on the lunar surface, trapped within natural glasses or between debris grains. Previous observations have suffered from ambiguity between water and its molecular cousin hydroxyl, but the new detection used a method that yielded unambiguous findings.
The only way for this water to survive on the sunlit lunar surfaces where it was observed was to be embedded within mineral grains, protecting it from the frigid and foreboding environment. The researchers used data from the SOFIA airborne observatory, a Boeing 747SP aircraft modified to carry a telescope.
“A lot of people think that the detection I’ve made is water ice, which is not true. It’s just the water molecules – because they’re so spread out they don’t interact with each other to form water ice or even liquid water,” Honniball said.

The second study, also published in the journal Nature Astronomy, focused upon so-called cold traps on the moon, regions of its surface that exist in a state of perpetual darkness where temperatures are below about negative 260 degrees Fahrenheit (negative 163 degrees Celsius). That is cold enough that frozen water can remain stable for billions of years.
Using data from NASA’s Lunar Reconnaissance Orbiter spacecraft, researchers led by planetary scientist Paul Hayne of the University of Colorado, Boulder detected what may be tens of billions of small shadows, many no bigger than a small coin. Most are located in the polar regions.
“Our research shows that a multitude of previously unknown regions of the moon could harbor water ice,” Hayne said. “Our results suggest that water could be much more widespread in the moon’s polar regions than previously thought, making it easier to access, extract and analyze.”
NASA is planning a return of astronauts to the moon, a mission envisioned as paving the way for a later journey carrying a crew to Mars. Accessible sources where water can be harvested on the moon would beneficial to those endeavors.
“Water is not just constrained to the polar region. It’s more spread out than we thought it was,” Honniball said.
Another mystery that remains unsolved is the source of the lunar water.
“The origin of water on the moon is one of the big-picture questions we are trying to answer through this and other research,” Hayne said. “Currently, the major contenders are comets, asteroids or small interplanetary dust particles, the solar wind, and the moon itself through outgassing from volcanic eruptions.”

Earth is a wet world, with vast salty oceans, large freshwater lakes and ice caps that serve as water reservoirs.
“As our closest planetary companion, understanding the origins of water on the moon can also shed light on the origins of Earth’s water – still an open question in planetary science,” Hayne added.
