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.

Space Stories: ESA & China Are Smiling, Blue Origin Beats SpaceX to the Moon, and JWST Analyzes Exoplanet Atmosphere

Here are some recent space-related stories.

European Space Agency: Smile Lifts Off on Quest to Reveal Earth’s Invisible Shield Against the Solar Wind

The Smile spacecraft lifted off on a Vega-C rocket from Europe’s Spaceport in French Guiana at 04:52 BST / 05:52 CEST (00:52 local time) on 19 May 2026. The launch marks the beginning of an ambitious mission to better understand solar storms, geomagnetic storms, and the science of space weather…Smile is a collaboration between the European Space Agency (ESA) and the Chinese Academy of Sciences (CAS). It will reveal how Earth responds to the streams of particles and bursts of radiation from the Sun, using an X-ray camera to make the world’s first X-ray observations of Earth’s magnetic shield, and an ultraviolet camera to watch the resulting northern lights non-stop for 45 hours at a time.

The Guardian: “Nasa Selects Jeff Bezos’s Blue Origin for First of Three Uncrewed Lunar Missions

Nasa announced on Tuesday ambitious plans for three uncrewed lunar missions this year to kickstart construction of a $20bn moon base, and said it had chosen the Amazon founder Jeff Bezos’s Blue Origin, ahead of Elon Musk’s SpaceX, to conduct the first...[NASA’s Administrator] said the three missions planned for 2026 would be followed by “more than a dozen” more in the coming years to test systems and equipment. He said the highly successful Artemis II mission last month that sent four astronauts around the moon for the first time since 1972 had been both a catalyst and incentive to advance the moon base plan.

Astrobiology: Astronomers Observe Exoplanet Atmospheres With New Cloud-detecting Method

Every morning, clouds roll in, and by evening, they have cleared off. This sounds like a weather forecast for a coastal city here on Earth — but it’s for WASP-94A b, a well-studied gas giant orbiting a star located nearly 700 light-years away. A new study published in the journal Science documents the first detection of repeating cloud cycles on a hot Jupiter exoplanet. The first author of the study is Sagnick Mukherjee, a 51 Pegasi b postdoctoral fellow at Arizona State University’s School of Earth and Space Exploration. Mukherjee is part of a research team that analyzed data from the James Webb Space Telescope targeting WASP-94 A b, a gas giant in the constellation Microscopium. The team discovered that the planet’s morning side is blanketed in clouds of magnesium silicate, the same mineral found in common rocks, while its evening side is under clear skies.
