China conducts parachute tests for returning asteroid sample to Earth

China has successfully conducted tests of the parachute design that will be used by the sample return capsule of its Tianwen-2 mission to grab samples from the near Earth asteroid dubbed 469219 Kamoʻoalewa.

The mission will launch on a Long March 3B rocket in 2025, and rendezvous with the asteroid in 2025. After getting its samples and releasing the sample return capsule, the plan is to then send Tianwen-2 to Comet 311P/PANSTARRS, arriving in the 2030s.

The probe uses fanlike solar panels, apparently copied from those used by NASA’s Lucy asteroid probe. China also has copied the touch-and-go sample grab methods used by OSIRIS-REx and Hayabusa-2, but it will also try its own original idea, to anchor to the asteroid and use drills in the probe’s landing legs.

SpaceX completes six-engine static fire test of Starship prototype #25

SpaceX yesterday successfully completed a six-engine static fire test of Starship prototype #25, the prototype that will be stacked on top of Superheavy prototype #9 and flown on the next orbital test flight.

Musk said in an interview on Saturday that more than a thousand upgrades were planned before the next flight of the Starship/Super Heavy. Including a significant change to the stage separation system that will see the Starship ignite its engines while still attached to the Super Heavy. Improvements are also being made to the Raptor engines to prevent leaks of super-heated gas which resulted in multiple engine failures during the April launch.

Major repair work and modifications are also underway to the Starship launch pad, after extensive damage occurred during the April 20 test flight.

Musk has also said the company will be ready to launch by August. While it is certainly possible that engineering will cause a slight delay to that schedule, more likely SpaceX will be ready, and then have to sit and wait for the FAA and the Biden administration to issue a launch permit. I am predicting it will not be issued by then, and likely not for months afterward.

South Korea recovers North Korea’s failed spy satellite

South Korea officials have revealed that their salvage operation has recovered the North Korean spy satellite that was lost when its rocket failed during launch on May 31, 2023.

The satellite, known as Malligyong-1, is reported to be designed to take high-resolution images of Earth to provide intelligence for the reclusive country’s military.

Pieces of debris believed to be the Chollima Type 1 rocket used for the mission were recovered just days after the attempted launch, Reuters reported on June 15. South Korea’s Yonhap News Agency is now reporting that the South Korean military has salvaged “an object believed to be a military reconnaissance satellite,” offering a valuable opportunity to learn about the spacecraft and its planned capabilities.

We should not expect South Korea to tell us much of what it finds. I predict the satellite will be very unsophisticated, and to reveal that would not serve the purposes of the South Korean government, which benefits from overstating North Korean military capabilities. North Korea is certainly a threat to South Korea, but all governments always take advantage of such threats to expand their power.

All told South Korea had recovered about 180 pieces of debris, including parts of the failed rocket. The salvage operations are continuing.

Russians launch weather satellite and 42 smallsats

Russians today successfully launched a Russian weather satellite plus 42 smallsats on a Soyuz-2 rocket, lifting off from Vostochny in Russia’s far east.

Almost all of the secondary payloads were Russian. The one exception known was a demo cubesat from the United Arab Emirates (UAE), apparently built by its own engineers and flown to test their growing capabilities. Previous UAE satellites and probes have previously been built by others and used to train UAE engineers.

The leaders in the 2023 launch race:

43 SpaceX
24 China
9 Russia
5 Rocket Lab

American private enterprise now leads China in successful launches 49 to 24 in the national rankings, and the entire world combined 49 to 41, with SpaceX by itself still leading the rest of the world, excluding other American companies, 43 to 41.

A northern lowland ice sheet on Mars?

A northern lowland ice sheet on Mars?
Click for original image.

Cool image time. The picture to the right, cropped to post here, was taken on March 14, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). Dubbed simply a “terrain sample,” this image was likely taken not as part of any specific research project, but to fill a gap in the camera’s schedule in order to maintain its temperature by taking regular images. When the camera team needs to do this, they try to find interesting locations not previously photographed. Sometimes the photos turn out somewhat boring. Most of the time however they capture something very intriguing.

In this case, the intriguing feature of this picture is its stippled surface that seems to overlay a relatively flat surface underneath, with some faint covered craters visible. On top are several more recent craters that suggest either the impact landed in very soft material, thus producing little ejecta and no crater rims or the craters are not craters but sinks, places where the ground is subsiding due to some underground process.

Japan’s military tests using Starlink for communications

Japan’s Self-Defense Forces (SDF) have been testing since March the use of SpaceX’s Starlink constellation to augment that nation’s own geosynchronous communications satellites.

Japan’s Defense Ministry signed a contract with an agent that provides SpaceX’s services to equip units of the Air, Ground and Maritime SDF with Starlink antennas and other communication devices. The SDF has been using the service at about 10 locations, including bases and camps, to verify whether there are any operational issues.

The ministry currently has two of its own X-band communication satellites in geostationary orbit about 36,000 kilometers above Earth for SDF units to use. The Starlink deal marks the first time the SDF is using a private-sector satellite constellation in low orbit.

An agreement with another company that provides a similar service will be concluded during the current fiscal year. [emphasis mine]

The goal is to provide Japan redundant communications capabilities in case China or Russia — both of which have become more aggressive militarily in the past few years — attempt to take out its own satellites. The highlighted sentence strongly suggests a deal with OneWeb is also being negotiated.

Webb makes first detection of one particular carbon molecule

The uncertainty of science: Using the Webb Space Telescope, astronomers have made the first detection of methyl cation (pronounced cat-eye-on) (CH3+) in space, located in a baby solar system the star-forming region of the Orion nebula about 1,350 light years away.

While the star in d203-506 is a small red dwarf, the system is bombarded by strong ultraviolet (UV) light from nearby hot, young, massive stars. Scientists believe that most planet-forming disks go through a period of such intense UV radiation, since stars tend to form in groups that often include massive, UV-producing stars.

Typically, UV radiation is expected to destroy complex organic molecules, in which case the discovery of CH3+ might seem to be a surprise. However, the team predicts that UV radiation might actually provide the necessary source of energy for CH3+ to form in the first place. Once formed, it then promotes additional chemical reactions to build more complex carbon molecules.

Broadly, the team notes that the molecules they see in d203-506 are quite different from typical protoplanetary disks. In particular, they could not detect any signs of water. [emphasis mine]

In the next day or so we shall likely see a number of stories in the mainstream press shouting some variation of “Webb finds key element of life!” Webb has done no such thing. It has found a carbon molecule not seen previously, which simply provides scientists another small data point in trying to understand the development of complex solar systems.

The highlighted sentences make clear the uncertainty in this field and the general shallow amount of knowledge. For example, why carbon molecules but no water, which is made up of hydrogen and oxygen, both ubiquitous throughout the universe and found in large amounts in star-forming regions?

Determining whether a Martian crater is impact or volcanic

Determining whether a Martian crater is impact or volcanic

Overview map

Cool image time! The picture above, rotated, cropped, reduced, and sharpened to post here, was taken on March 22, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). The camera team labeled this “Crater rim and ejecta,” which subtly reveals the picture’s scientific purpose.

The white dot on the overview map to the right indicates the location of this 15-mile-wide unnamed crater, about 150 miles northwest of where the rover Opportunity landed and traveled south to the rim of Endeavour Crater. It also shows in the inset that the crater appears to sit in the center of an upraised mound, suggesting it was formed not by impact but by volcanic processes.

This picture however says otherwise. The many small mounds and mesas to the south of the crater rim are not what one would expect on the apron of a volcano. Instead, they suggest this crater is an impact, with those mounds the eroded ejecta from that impact, now also partly buried by dust. This hypothesis is strengthened by the data from Opportunity, which found a great deal of impact ejecta during its travels, possibly from the very event that created this crater.

Will the wreck of the submersible Titan and the death of its five passengers impact space tourism?

OceanGate's Titan submersible
OceanGate’s Titan submersible

Three articles today all asked the same question as I pose above in the headline, noting the similarity in the business model of the deepsea tourism company OceanGate Expeditions and the burgeoning space tourism business, including both suborbital and orbital flights.

Without question there will be many more such articles in the coming days, as more information is gathered about what caused the failure of the Titan. As these three articles do, all will note the similarities and differences between deep sea tourism and space tourism.

First the differences. » Read more

Rocket Lab to attempt full recovery of first stage on next launch

In announcing the launch window, opening July 14th, for its next New Zealand launch, Rocket Lab also revealed that it will attempt the full recovery of the first stage after it splashes down softly in the ocean using parachutes.

Rocket Lab is also planning to conduct a marine recovery of Electron’s first stage as part of this mission. Rocket Lab’s recovery team will retrieve Electron using a customized vessel and transport the stage back to Rocket Lab’s production complex for analysis. Data from this recovered stage will inform Rocket Lab’s ongoing recovery and reuse program.

The company recently decided to forego any further attempts to snatch the first stage in the air before splashdown using a helicopter. Instead, it thinks it can recover the stage in good enough condition out of the water to use it or its engines again.

The launch itself will carry seven smallsats, four for NASA and three for two commercial companies.

House Democrats propose and Republicans approve Space Force increasing spaceport fees

We’re here to help you! The House Armed Services Committee, controlled by a majority of Republicans, has approved a defense funding bill that includes an amendment, proposed by a Democrat, that would allow the Space Force to charge much larger fees for the use of its spaceports.

Committee members signed off on the legislation June 22, which proposes $874 billion in defense spending. The full House is slated to vote on the bill in July. Included in the bill is an amendment offered by Rep. Salud Carbajal, D-Calif., that would allow the Space Force to collect fees from companies for the indirect costs of using the military’s launch ranges, like overhead infrastructure or other charges that a traditional port authority might impose on its users.

Today, per the Commercial Space Launch Act of 1984, the service is limited to collecting fees for direct costs like electricity at a launch pad. The law also restricts the Space Force from accepting in-kind contributions from commercial companies to upgrade its ranges.

The committee’s bill, if approved, would require commercial launch companies to “reimburse the Department of Defense for such indirect costs as the Secretary concerned considers to be appropriate.”

The bill also includes a Republican amendment that encourages the Space Force to charge other additional fees, or require private companies to do work the Space Force is presently handles.

Though the latter amendment might make sense, both amendments will likely achieve just one thing: making it much more expensive to launch from Cape Canaveral and Vandenberg. Whether those increased costs will be kept as low as possible is entirely unknown. We certainly should not trust officials in the federal government to do so.

Ariane-6 engineering test rocket at launchpad for engine tests

Ariane-6 test version at launchpad
Click for original image.

An engineering test version of ArianeGroup’s Ariane-6 rocket has arrived at the launchpad in French Guiana, where it will undergo a series of static fire engine and fueling tests.

As seen in this image [to the right] taken on 22 June 2023, the doors of this mobile gantry have been opened and the structure rolled back on rails. The operation, which takes about half an hour, was a trial run in preparation for a series test firings of the Vulcain 2.1 engine. These test firings will be conducted on the launch pad as part of ongoing preparations for the first-ever flight of Ariane 6. Removing the gantry for the first time – and then returning it – also helped validate the Ariane 6 ground infrastructure.

The Ariane 6 rocket visible here is not intended for flight. It is being used to check assembly procedures, electrical and fuel connections, telemetry, etc. Flight models, including the rocket that will make Ariane 6’s inaugural flight, are being built in Europe and integrated by prime contractor Ariane Group. After shipping to French Guiana, Ariane 6 core and upper stages are assembled horizontally, before being transferred to the launch pad and lifted upright inside the gantry, where the solid-fuel boosters and payload are attached. The horizontal assembly method cuts the time and cost of a launch campaign, and is a first for an Ariane rocket.

With only one Ariane-5 rocket launch left on its manifest, the European Space Agency desperately needs to get Ariane-6 off the ground and operational. It was originally supposed to make its first launch in 2020, thus overlapping the final launches of Ariane-5 by several years. At this moment it appears there will be a gap between when one rocket retires and the other begins flying.
