The Philippine Space Agency (PhilSA) posted a heads up public advisory for incoming debris from China’s Long March 3B rocket launched today from the Xichang Satellite Launch Center.
China’s Long March-3B carrier rocket propelled into orbit on December 29th the Shiyan-10 02 satellite to be used for in-orbit verification of new space technologies, such as space environment monitoring.
Unburned debris
Meanwhile, PhilSA recommended “precautionary measures related to expected unburned debris from the Long March 3B rocket.” PhilSA issued an advisory to all relevant government agencies on the estimated drop zone area and proposed the issuance of appropriate warnings on air and marine access.
The launch vehicle leftovers, such as the rocket boosters and payload fairing, were projected to fall within a drop zone area located within the vicinity of Recto bank.
“While not projected to fall on land features or inhabited areas within the Philippine territory, falling debris poses danger and potential risk to ships, aircraft, fishing boats, and other vessels that will pass through the drop zone,” according to a PhilSA statement.
Public caution
The actual drop zone area, PhilSA added, may change because of various factors such as the Earth’s rotation, weather, and climate conditions.
“There is also a possibility for the debris to float around the area and wash toward nearby coasts. Furthermore, the possibility of an uncontrolled re-entry to the atmosphere of the rocket’s upper stages returning from outer space cannot be ruled out at this time,” PhilSA stated.

PhilSA reiterated its earlier public advisory to immediately inform local authorities if suspected debris is sighted. PhilSA also cautioned the public against retrieving or coming in close contact with these materials that may contain remnants of toxic substances such as rocket fuel.
Russia’s Roscosmos and China’s National Space Administration signed a cooperation program of space activities for 2023-2027.
According to Roscomos, as reported by the TASS news agency, the cooperative agreement was signed at the end of last month.
This year, Roscomos emphasized, the Russian Federation and China continued to intensify cooperation in the space sector.

Lunar station
One element of cooperative work between the two nations is establishment of the International Scientific Lunar Station (ISLS).
Previously, Roscosmos and the China National Space Agency (CNSA), as part of the Global Conference on Space Exploration (GLEX-2021), presented a roadmap for the lunar outpost.
According to TASS, construction of the ISLS should be fully completed by 2035.

Step-by-step
In earlier, step-by-step stages from 2026 to 2030, two robotic Moon missions are planned to develop technologies for landing and delivering cargo, as well as returning samples of lunar rock to Earth.
From 2031 to 2035, infrastructure in lunar orbit and on the surface of the Moon, including communications systems, as well as electrical power, research and other equipment are to be put in place.
Per the project’s roadmap, the station’s transport infrastructure will include research and technical lunar rovers, as well as a jumping robot.
The parties plan to equip the station with several smart mini-rovers designed to explore the surface of the Earth’s natural satellite.
China is purportedly moving forward on a new booster tied to the country’s human spaceflight plans for a piloted Moon landing.
Recently speaking at a youth forum gathering, Wu Yansheng, chairman of the Aerospace Science and Technology Corp (CASC) — China’s largest space contractor — said that the new rocket is codenamed “Rocket 921” and is to carry an orbiter vehicle with three persons on board and a two-member Moon lander.
Wu said that the Moon program launcher is likely to be ready for flight by 2027, as reported by the South China Morning Post.

The troubled Russian Soyuz MS-22 that suffered a coolant leak at the International Space Station continues to garner top-level attention as to the craft’s status.
A recent meeting held at Russia’s TsNIIMash, the country’s rocket and spacecraft scientific center, brought experts together to confer about the situation, focused on the damaged crew-carrying craft.
Earlier, Russia’s Roscosmos stated that two working groups have been established to determine the causes of the emergency situation and analyze the technical condition of the spacecraft.
These groups were also charged with developing recommendations for further actions by ground specialists and the crew of the Russian segment of the station.
The working group experts must decide on the possibility or impossibility of further use of the Soyuz MS-22 spacecraft to return astronauts to Earth, which is planned for March 2023, Roscosmos explained.
Should I stay, should I go?
In a recent posting on the official Roscosmos Telegram channel, it has been reported the groups did establish that the breakdown of the ship’s thermal control system radiator occurred due to external mechanical damage.
That external problem could have been caused by a micrometeoroid or space debris striking the spacecraft’s external cooler-radiator.
Making use of a camera-mounted robotic arm inspection, close-up imagery of the problem area was taken to help assess the issue.
On one hand, a decision could be made to quickly prepare for launch of an uncrewed Soyuz MS-23 to replace the compromised Soyuz MS-22. Alternatively, a decision could be made to carry out a regular crew change of the ISS Russian segment.
The new Roscosmos Telegram channel posting indicates that in January 2023, based on the conclusions of the working groups, a special commission will make organizational decisions on the further actions of ground specialists and the crew of the ISS Russian Segment, as well as on a possible change in the ISS flight program.

Russia’s Roscosmos has proposed extending the country’s use of the International Space Station until 2028, for now.
In an interview with the Interfax News Agency, Sergei Krikalev, Roscosmos Executive Director for Manned Space Programs, said that documents for Russia’s further ISS operation have been submitted to the government for consideration and coordination.
“For now, we are talking about 2028,” veteran cosmonaut Krikalev told Interfax. “Historically, extensions have been made for four years: we had an agreement until 2020, and now it is valid until 2024. We can extend it until 2028 and then make a decision depending on the situation and analysis of technical and program feasibility,” he said.
As noted by Interfax, the current agreement on ISS operation expires in 2024.
Roscosmos head, Yury Borisov, previously said that Russia’s exit from the ISS project should be synchronized with the start of construction of a new Russian space station.
Wait a Minute!
Space hardware tumbling out of orbit may lead to new unforeseen impacts on the environment and climate.
Due to the growing scale and pace of launch activities what is needed is better monitoring of the situation, as well as regulation to create an environmentally sustainable space industry.

Spritacular is a citizen science project led by NASA’s Goddard Space Flight Center that aims to collect observations of sprites and other optical phenomena occurring above the thunderstorms – collectively known as Transient Luminous Events (TLEs).
The database generated from these observations will lay the groundwork for first-ever event catalog of TLEs that will greatly contribute to advancement of scientific studies.
Atmospheric events
Over the last two decades, good quality cameras have become increasingly affordable which allowed more people than ever before to have access to the tools capable of documenting these powerful atmospheric events.
Spritacular project strives to establish a collaborative bridge among communities that are actively engaged in chasing these elusive phenomena, newcomers looking to learn more, and the researchers of atmospheric and space electricity.

An international open letter is calling upon leading space agencies to reduce risks from uncontrolled reentries of rocket bodies and other space objects.
The Outer Space Institute (OSI) published the December 19th call to action for “multilateral negotiations on a controlled reentry agreement.”
OSI is based at the University of British Columbia in Vancouver.
The Institute is a global network of space experts that addresses grand challenges facing the continued use and exploration of space.

Reentry regime
“The uncontrolled reentry of space objects presents a significant, cumulative, fast-growing risk to human beings around the world. Uncontrolled rocket bodies are of particular concern,” states the letter to space agency leaders.
“We call on your agencies, working with your states’ foreign ministries, to initiate multilateral negotiations on a controlled reentry agreement, starting with rocket bodies. Recognizing that such negotiations take time, we further call on each of your states to unilaterally commit to a national controlled reentry regime,” the letter states.

Casualty risks
While the letter focuses on the casualty risks from uncontrolled rocket body reentries, it also flags uncontrolled satellite reentries as a concern, “and may eventually dominate the casualty risk should tens of thousands of medium-sized to large satellites be placed into orbit.”
The OSI open letter suggests a reentry regime that first starts with rocket bodies, then expanded to satellites to reduce all uncontrolled reentry risks.
“Simply hoping that uncontrolled reentries will not cause harm is an unsustainable strategy. With leadership, cooperation and global goodwill, these preventable and therefore unnecessary dangers can be greatly reduced,” the letter concludes.
Space fallout
Cited in the letter are accounts of uncontrolled space junk reaching land. For example, pieces of a Chinese Long March 5B rocket damaged buildings in the Ivory Coast in 2020.
In July 2022, the breakup of another Long March 5B was visible from the ground in Borneo, and sizable pieces were later found.
On November 4, 2022, another Long March 5B reentered over the Pacific Ocean southwest of Guatemala.
Fuel tanks, pressure vessels
China is not the only actor allowing rocket bodies to reenter in uncontrolled ways, the letter explains.
In 2016, a U.S. SpaceX Falcon 9 second stage was abandoned in orbit, reentering over Indonesia with two refrigerator-sized fuel tanks reaching the ground intact.
In 2018, a number of smaller titanium pressure vessels from a Russian Zenit upper stage reached the ground in Peru.

A drag sail has been successfully deployed in a test meant to showcase the ability to hasten a spacecraft’s reentry and help curb the continuing and uncontrolled pollution of space.
The Drag Augmentation Deorbiting Subsystem (ADEO), carried by D-Orbit’s ION spacecraft, was launched by a SpaceX Falcon 9 booster on June 30, 2021.
This autonomous braking sail comes from the Munich-based space company High Performance Space Structure Systems.
The promise of ADEO is to complete deorbit of a spacecraft many years faster than current “unbraked” satellites.
