UPDATE: A tweet from China shows that the strap-on boosters of this rocket crashed near homes in China, though no one was hurt.

Original post:
—————–
The Philippine government issued a statement yesterday warning the public about possible debris from the December 29th launch by China of its Long March 3B rocket.

The Philippine Space Agency (PhilSA) is recommending precautionary measures related to expected unburned debris from the Long March 3B rocket scheduled for launch today between 12:33 PM and 01:10 PM Philippine time from the Xichang Satellite Launch Center in Xichang, Sichuan Province, China. Upon confirmation of planned launch dates, PhilSA immediately 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.

Based on the Notice to Airmen (NOTAM) issued by the Civil Aviation Administration of China (CAAC) to the Civil Aviation Authority of the Philippines (CAAP), expected unburned debris, such as the rocket boosters and payload fairing, is projected to fall within a drop zone area located within the vicinity of Recto bank, approximately 137 kilometers from Ayungin Shoal and 200 kilometers from Quezon, Palawan. The unburned debris is designed to be discarded as the rocket enters outer space. 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.

Though the drop zone avoided inhabited areas, it included regions where fisherman worked, and the flight path still flew over inhabited areas. The risk was extremely low, but it appears China also made no effort prior to launch to coordinate this situation with other governments, such as the Philippines. Its warning apparently arrived just before launch. Thus, there was risk that Filipino fisherman were in the drop zone at launch.

South Korea test flies a solid-fueled missile

9:00 am

South Korea has successfully completed the second test flight of a solid-fueled missile.

The test came after North Korea claimed earlier this month to have staged a test of a “high-thrust, solid-fuel” rocket motor to develop a “new-type” strategic weapon system.

…In March, the state-run Agency for Defense Development carried out the first test of an indigenous solid-fuel space rocket at a testing site in Taean, 150 kilometers southwest of Seoul, to confirm its capabilities.

The rocket is designed to put a small satellite into a low Earth orbit for surveillance operations. Compared with liquid-fuel space vehicles, solid-fuel ones are known to be usually simpler and more cost-effective to launch.

South Korea might claim this rocket is intended for launching smallsats, but its main purpose almost certainly is as a military missile to counter the missile program of North Korea that has accelerated since Joe Biden became president.

SpaceX successfully launches Israeli imaging satellite

12:53 am

SpaceX today successfully launched an Israeli Earth-observation satellite, using its Falcon 9 rocket.

The first stage successfully completed its eleventh flight, touching down softly at SpaceX’s facility at Vandenberg Space Force Base.

This launch completes SpaceX’s 2022 launch year, with a record 61 launches, one more than predicted by the company earlier in the year, and the most ever by a privately owned company.

The leaders in the 2022 launch race:

62 China
61 SpaceX
21 Russia
9 Rocket Lab
8 ULA

The U.S. now leads China 85 to 62, while trailing the rest of the entire world combined 94 to 85. The 85 launches for the U.S. is a new record for a single year, smashing the record of 70 launches set in 1966.

On Monday I will publish my annual full roundup of the state of global launch industry, based on the 2022 numbers.

China to build giant ground-based optical telescope

9:45 am

China has announced its plan to build ground-based multi-segmented optical telescope, similar in design to the 10-meter Keck Telescope in Hawaii.

Peking University wants to build the largest optical telescope in Asia and close the gap in astronomy capabilities with the rest of the world.

The project aims to create an initial telescope with an aperture of 19.7 feet (6 meters) by 2024; the mirror will be expanded to 26.2 feet (8 m) by 2030. The project, which in English is called the Expanding Aperture Segmented Telescope (EAST), is being led by Peking University.

Like Keck, the primary mirror would be made of smaller segments, fitted together to create the larger mirror. While not as large as Keck, EAST would be among the largest in the world.

China’s Long March 3B rocket launches “experimental satellite”

9:20 am

China today successfully used its Long March 3B rocket to launch from an interior spaceport what its state-run press labeled an “experimental satellite.”

No word on where the rocket’s strap-on side boosters or first stage crashed within China.

The leaders in the 2022 launch race:

62 China
60 SpaceX
21 Russia
9 Rocket Lab
8 ULA

The U.S. still leads China 84 to 62 in the national rankings, but trails the entire world combined 94 to 84.

This launch cements for China the top spot in launches over SpaceX, since SpaceX only has one more launch planned in 2022, scheduled for just before midnight tonight.

Lex Fridman – Playing Guitar in a Self-Driving Car

6:01 pm

An evening pause: The guitar playing is great, but if this is supposed to be a demonstration of the abilities of self-driving cars, to me it is a utter failure. The drive was on a test track, with no other cars. The car itself was probably never going faster than 25 miles per hour.

In fact, if anything this proves the impracticality of self-driving cars. Such technology might work in a completely controlled environment, but as soon as you add any random human element, it can’t work. Thus our options: we continue to drive ourselves, or we give up our freedom to drive so that all vehicles can be autonomous.

But as I say, the guitar playing is great.

SpaceX launches 54 more Starlink satellites

9:04 am

SpaceX early today completed its 60th successful launch in 2022, putting 54 Starlink satellites into orbit using its Falcon 9 rocket.

This achievement matches a prediction Elon Musk made early in 2022. More significant, except for two years (1965 and 1966), SpaceX completed more launches in 2022 than the United States achieved each year since Sputnik. And it did it not as a nation, but as a private company, for profit.

SpaceX’s achievement this year also allowed the U.S. to smash its own record for annual launches.

The first stage successfully completed its 11th flight, landing on a drone ship in the Atlantic.

The leaders in the 2022 space race:

61 China
60 SpaceX
21 Russia
9 Rocket Lab
8 ULA

The U.S. now leads China 84 to 61 in the national rankings, but trails the entire world combined 93 to 84.

Only one more launch, by SpaceX, is publicly scheduled for 2022.

SpaceX has about 100 Starlink terminals working in Iran

8:47 am

Though the Iranian government opposes their use, according to a tweet by Elon Musk SpaceX now has almost 100 Starlink terminals working in Iran.

Elon Musk announced that SpaceX has almost 100 Starlink terminals active in Iran. SpaceX activated Starlink services in Iran in September, supporting the United States’ stance on providing internet freedom and free flow of information to Iranians.

Unlike Ukraine, SpaceX does not have the cooperation of the Iranian government to expand Starlink services in the country. In Ukraine, President Volodymyr Zlenskyy and the Minister of digital transformation Mykhailo Feorov have actively supports Starlink connection during the war with Russia.

In contrast, the Iranian government is actively trying to limit its citizens’ internet access. The United States government has taken a stance against the Iranian government’s decision regarding internet access for its people.

SpaceX has routinely cooperated with foreign governments before selling terminals, likely because to do otherwise would get it in trouble with the U.S. State Department. In this case however the State Department appears to have approved this action, and SpaceX then made it happen.

China launches Earth observation satellite

8:41 am

China today successfully launched a classified Earth observation satellite using its Long March 4B rocket.

As the launch was from an interior spaceport, the rocket’s lower stages landed somewhere in the interior of China.

The leaders in the 2022 launch race:

61 China
59 SpaceX
21 Russia
9 Rocket Lab
8 ULA

The U.S. still leads China 83 to 61 in the national rankings, but trails the entire world combined 93 to 83.

At the moment, the only known remaining launches in 2022 are two SpaceX Falcon 9 launches. However, China routinely launches a lot in the November/December timeframe, so we should not be surprised if they complete one or two launches as well in the next few days.

NASA requesting proposals for raising Hubble’s orbit

9:23 am

NASA has published a request for proposals from the private commercial space industry for a possible future mission to raise Hubble’s orbit.

NASA published a request for information (RFI) Dec. 22 asking industry how they would demonstrate commercial satellite servicing capabilities by raising the orbit of Hubble. The agency said it is looking for technical information about how a company would carry out the mission, the risks involved and the likelihood of success.

NASA emphasized in the RFI that it had no plans to procure a mission to reboost Hubble. “Partner(s) would be expected to participate and undertake this mission on a no-exchange-of-funds basis,” the document stated, with companies responsible for the cost for the mission.

Apparently, this RFI was issued as a direct result of the agreement between NASA and SpaceX to study a Dragon mission to do exactly this, which in turn was prompted by Jared Isaacman, as part of his private Polaris program of manned Dragon/Starship space flights. I suspect that NASA officials realized that not only were their engineering advantages to getting more proposals, there were probably legal and political reasons for opening the discussion up to the entire commercial space community.

Ideally, a Hubble reboost mission should occur by 2025, though the telescope’s orbit will remain stable into the mid-2030s.

Australian rocket startup Gilmour preps for first test launch

9:23 am

Gilmour Space Technologies, a new Australian rocket startup, is now targeting April for the first test launch of its three-stage Eris rocket from a launchpad on the northeast coast of Australia.

Standing 25 m (82 ft) high, [Eris] has a first-stage diameter of 2 m (6.6 ft), and a second-stage diameter of 1.5 m (4.9 ft), and it’s designed to take a payload mass up to 305 kg (672 lb) up as high as 500 km (311 miles) for delivery to sun-synchronous or equatorial orbits. The Eris will be powered by five of Gilmour’s own Sirius rocket engines. This is a hybrid engine, meaning it uses a liquid oxidizer but a solid fuel. In a final bench test to destruction, it generated 115 kilonewtons (25,850 lbf) and burned for more than 90 seconds before exploding.

Update on upcoming first launch of Relativity’s Terran-1 rocket

9:13 am

Link here. Relativity has been doing longer and longer static fire tests on the launchpad, building to what could be the first every full duration static fire test of a rocket, on the launchpad.

A pair of spin-start tests on Terran 1’s first stage was completed on July 18 and 21 of this year. This was followed by hot fire tests, which not only started the nine Aeon 1 engines but allowed them to reach full thrust before shutdown. The first of these hot fire tests occurred on July 27 and lasted six seconds.

Once complete engine ignition was achieved, the next goal was to work toward firing the first stage for the full duration that will be needed during the flight from liftoff to stage separation. This type of “mission duty cycle” test is usually done on dedicated test stands rather than on the launch pad, but the test stand being used in place of the launch mount at SLC-16 enabled Relativity to streamline operations and complete long-duration firings on the launch pad. “To our knowledge, no other company has ever actually done a full flight duration test on the actual launch mount, or launch pad, at Cape Canaveral,” said Relativity CEO Tim Ellis, in an August interview with NASASpaceflight.

.

Once this test is completed, the rocket will be rolled back to its assembly building for check-outs, and if all is well will then be returned to the launchpad for its actual launch. No date has been set for that launch, but if it occurs before SpaceX’s Starship orbital launch, it will be the first methane-fueled rocket to reach orbit.
