This week’s image comes from a Chinese probe called Tianwen-2. It shows the spinning asteroid 2016 HO3, or Kamo‘oalewa, which is labeled by some of a “quasi-moon” of Earth until it decides to move on. Unlike the actual Moon, this asteroid is simply joining the Earth as it circles the Sun. The asteroid is about the size of a school bus.

The Chinese probe, launched from China in May 2025, is believed to have started its orbit of asteroid Kamo‘oalewa on June 6th of this year. It is now believed to be a rubble-pile asteroid, meaning it is basically loose material rather than a solid object. Even so, the Chinese probe may try to grab a sample to be returned to Earth in November 2027.

The source of the asteroid is still being debated, with some believing it is a piece of the Moon dislodged by an incoming asteroid while others believe it comes from the main asteroid belt.

In a paper released last year, scientists were leaning towards its origin being the main asteroid belt, noting:

Quantitative estimates show that population models of [Near Earth Asteroids] based on the migration of objects from the main belt are capable of accounting for Kamo‘oalewa-like objects. This relative contribution supports the hypothesis that (469219) Kamo‘oalewa originated from the main belt, which will be further investigated by future observations and in situ exploration of the Tianwen-2 spacecraft.

How long will it remain Earth’s partner? Back in 2021, Renu Malhotra, a UArizona planetary sciences professor, stated:

It will not remain in this particular orbit for very long, only about 300 years in the future, and we estimate that it arrived in this orbit about 500 years ago.

China Also Has a Reusable Rocket

Earlier today China successfully recovered the first stage of its Long March 10b rocket (as shown above and also in a CNN video). The rocket was launched from Hainan island in southern China. 

Up to this point, only SpaceX and Blue Origin have been able to accomplish this feat. This means China is joining the U.S. in terms of reusable rockets at a time when it is also making strides in the race to the Moon.

The rocket test was also successful in putting a satellite into low-Earth orbit.

The Long March 10b rockets was built by a state-owned company and is an essential part of China’s plans to send a crew to China. It is also said to be part of China’s plans to put internet satellites into orbit, similar to SpaceX’s Starlink.

One interesting part of the recovery was the use of a large net on the platform. Chen Muye from the China Aerospace Science and Technology Corporation (the state-owned company) stated:

Net-based recovery simplifies the onboard structure, reduces weight and boosts payload capacity.

Maybe the US commercial space sector has a few things to learn from the Chinese.

Space Quote: The Taikonauts Are Coming!

“Well, I would just say, first, it’s not arguably like there- we are very much in a space race right now, and the Chinese are moving at incredible speeds, and they are certainly capable of doing what the Soviets were not during the- the first space race. The Chinese will land their taikonauts on the moon. There’s no question. The question is, will the United States return before them, and will we do so in a different way this time, when we build a base, establish that enduring presence? I think the answer is yes.“

-Statement by NASA Administrator Jared Isaacman on CBS’s Face the Nation this past Sunday. The interview addresses other issues in addition to the Artemis mission to the Moon, including efforts to save the Swift space telescope as well as the status of Blue Origin’s efforts to recover from the recent explosion of its New Glenn rocket.

A Day in Astronomy: Dogs in Space

On this day in 1960, the Soviet Union sent two dogs into space on a sub-orbital flight – Otvazhnaya and Malyok. Both returned from the trip safely.

Between 1951 and 1966, it is estimated that the Soviets sent 48 dogs into space on both sub-orbital and orbital flights, while China sent only two dogs into space on sub-orbital flights. The United States did not send any dogs into space. Of the 48 Soviet dogs, 20 died in space. Both Chinese dogs survived.

Little Otvazhnaya, which means “brave” in Russian, flew on the most missions of any of the dogs. She flew on five sub-orbital missions between July 1959 and September 1960.

The most famous Soviet space dog, Laika (pictured above), was the first dog to fly on an orbital flight on November 3, 1957. She did not survive the mission.

One of the Russian canine cosmonauts has a link to the Kennedy family. Strelka, one of the first dogs to orbit the Earth and survive, had six puppies, including one named Pushinka, or “Fluffy.” Pushinka was presented as a gift to President John F. Kennedy’s family in 1961.

The Next Space Race May Blind Astronomers and the Rest of Us

While most of the attention regarding the space race with China revolves around the Moon at the moment, another space race is brewing that will become a big problem for astronomers if the race is successful. This second race is one to place data centers into orbit.

Over the years, astronomers have been expressing concerns about the impact that thousands of satellites on ground-based telescope. However, that is nothing compared to the number of data center satellites being planned for the future. SpaceX has already requested permission from the Federal Communications Commission for at least one million data center satellites. And other US companies such as Google with its Project Suncatcher, as well as the Chinese with similar investments, have their own plans to toss data centers into orbit.

We are fast-tracking ourselves towards the world of Disney’s WALL-E where we have polluted the night sky beyond recognition. Is this really necessary? Do we have other options?

Fortunately, we do, including Google’s planned data center in Texas, which will power itself from renewable energy. Another example is China’s efforts to put data centers in the ocean. Like the night sky, the ocean is a big place with a lot of possibilities if done right.

AI has already brought up enough concerns pertaining to childhood health, jobs for new graduates, and even a real armed Skynet determining its own targets. Do we really need to also surround the planet with more than a million satellites feeding into this questionable new world?

It may be time to take some of these decisions away from the stock market and ponder them for a few a little longer. Even Elon Musk was expressing such concerns in 2023. He signed a letter from the Future of Humanity Institute that stated:

Should we let machines flood our information channels with propaganda and untruth? Should we automate away all the jobs, including the fulfilling ones? Should we develop nonhuman minds that might eventually outnumber, outsmart, obsolete and replace us? Should we risk loss of control of our civilization? Such decisions must not be delegated to unelected tech leaders.

That was a smart idea then, and it makes even more sense today before we go crazy spending billions, if not trillions, or dollars on a new space race that re-energizes a questionable technology while blotting out the night sky for those who are willing to look outside of our planetary bubble to learn from the universe.

It was B. F. Skinner who said:

The real problem is not whether machines think but whether men do.
