Hydrogen leak detected during today’s SLS tank test

Though engineers have apparently overcome the issue so that today’s tank test of NASA’s SLS rocket can continue, a hydrogen leak was nonetheless detected during fueling.

The fueling tank test is not yet complete.

At this moment I cannot imagine the military’s range office will allow NASA to launch on September 27th, as the agency has requested. To do so will require the range to ignore the possibility that the flight termination is inoperable, as its batteries are past their use-by date by almost a month. Combined with these ongoing leak issues, it would be irresponsible to do otherwise.

Russia launches three astronauts to ISS; China launches Earth observation satellite

Russia today successfully used its Soyuz-2 rocket to launch three astronauts to ISS, two Russians and an American flying as part of the NASA-Roscosmos barter deal whereby each agency flies an astronaut from the other in order to make sure everyone knows how to use each other’s equipment.

China in turn today used its Long March 2D rocket to launch an Earth observations satellite into orbit.

The leaders in the 2022 launch race:

42 SpaceX
38 China
12 Russia
7 Rocket Lab
5 ULA

American private enterprise still leads China 58 to 38 in the national rankings, and is now tied with the entire world combined at 58.

InSight’s power level holding steady

InSight's on-going power levels

The Energizer bunny of Mars, the InSight lander, continues to hold on. The engineering team tonight issued another status report, as shown in the graph to the right. For the past week the lander continued to produce 420 watt-hours per day, even though the tau level of dust in the atmosphere increased from 0.8 to 0.85.

The tau level of dust outside of the winter dust season is normally between 0.6 and 0.7. Even though Mars is moving out of winter, that level has increased slightly above InSight. And yet, even with a higher dust content and thus less sunlight, the lander’s dust-covered solar panels are generating power, at a very slightly higher level.

The InSight team had expected the lander to die in early September, at the latest. Instead, it keeps running, thus allowing it to detect on September 5th an impact created by a cluster of three asteroids, the first time scientists have ever pinpointed exactly when such a new impact occurred on Mars.

For the lander to survive for even longer, all it needs is one gust of wind across the solar panels to clean them off. The science team had expected this to happen periodically, based on past experience with the Spirit and Opportunity rovers. Unfortunately for InSight, it has not yet happened even once since it arrived on Mars in 2018. Nonetheless, it only has to happen once to save the lander.

Stay tuned. All is not yet lost.

Jupiter’s endless interweaving storms

Jupiter's endless interweaving storms

Cool image time! The photo to the right, rotated so that north is up and then reduced slightly to post here, was created by citizen scientist Thomas Thomopoulos from a raw photo taken by Juno during its 44th orbit of Jupiter.

To bring out the details Thomopoulos enhanced the colors, then enlarged the entire photo and cropped the area of interest.

Unfortunately, the Juno team that releases these photos does not provide information for easily establishing scale. In an email to me Thomopoulos noted that the largest circular storm in the northern half of the image is likely a vortex, which on Jupiter tend to range from 600 to 3,500 miles in diameter. He also noted that Juno was a little less than 27,000 miles away from Jupiter when this photo was snapped on August 17, 2022. Thus, I suspect this particular vortex sits on the larger end of that size range, which makes it a little less than half the size of the Earth.

As for the colors, as with many similar Juno images, the white clouds appear to almost always sit at the top of these storms and jets, almost like thunderheads.

Though the largest feature here is that large vortex to the north, most of the gigantic Jupiter storms visible seem instead to form as bands, the storms churning about madly as they are driven along the gas giant’s very fast ten hour rotation period.

NASA releases new overall objectives for exploration of solar system

NASA today released a new roadmap for its goal of exploring the Moon, Mars, and the rest of the solar system, with the goal of providing an overarching strategy for everything it hopes to accomplish.

The resulting revised 63 final objectives reflect a matured strategy for NASA and its partners to develop a blueprint for sustained human presence and exploration throughout the solar system. They cover four broad areas: science; transportation and habitation; lunar and Martian infrastructure; and operations. The agency also added a set of recurring tenets to address common themes across objectives.

You can read the full document here [pdf].

The most astonishing thing about this roadmap is its utter lack of any mention of race or gender, especially when one considers how obsessed the Biden administration and its minions in federal bureaucracy have been over such things. The goals are entirely focused on exactly what they should be focused on, exploration and research, with the goal of partnering with as many private and governmental entities as possible to get it done in the most efficient way.

The strange scattered rocks of Gediz Vallis on Mars

The strange rocks of Gediz Vallis
Click for full image.

Cool image time! The photo to the right, reduced to post here, was taken on August 20, 2022 by Curiosity’s high resolution camera. It shows some of the scattered and very delicate rocks that it is finding on the floor of Gediz Vallis, the valley the rover had been striving for since landing more than a decade ago and finally entered in mid-August.

Because of Mars weak gravity, about 39% of Earth’s, and very thin atmosphere, about 1% of Earth’s, it is possible for surface rocks to erode into such delicate shapes. The shapes appear to be further encouraged by the many layers that exist in Mars, with each layer having different characteristics. In the case of the hanging flakes to the right, these layers were more resistant to erosion and thus remains intact while material above and below was slowly blown away.

Researchers develop strongest-yet 3D printed titanium

Capitalism in space: Researchers at Monash University in Australia have successfully developed a 3D printed titanium alloy that has an internal strength exceeding that of normal commercially produced titanium.

In tests, the team demonstrated that the new titanium alloy had both elongation and tensile strengths (stretching and tension, respectively) of over 1,600 MPa. For reference, most commercial titanium alloys top out at around 1,000 MPa. This is also the highest specific strength for any other 3D-printed metal alloy, the team says.

Since 3D printing is going to be the main industrial manufacturing process in space, this process and the titanium it produces is certainly going to looked at with great interest by those who wish to build things in space. Imagine having a 3D printer that can make strong titanium parts in almost any needed shape. The possibilities are endless.

Astrobotic to build solar power grid for use by others on Moon

Astrobotic's proposed lunar electric grid

Capitalism in space: Astrobotic yesterday announced its plan to build a solar power system on the Moon, using its rovers, thus reducing the weight and cost of other projects.

The graphic to the right illustrates how the system will work. First, vertically deployed solar panels, attached to a small rover, will unfold to produce power. These can be placed in many locations, thus providing each location a source of electricity. Second, an additional rover will be linked to the panel, providing power storage and a moveable wireless charger for transferring power to a customer’s equipment.

Astrobotic plans to begin deploying and demonstrating LunaGrid elements as early as 2026 with the goal of the first operational LunaGrid by 2028 at the lunar south pole. With LunaGrid power service available, a host of science, exploration, and commercial activity can begin sustained and continuous operation.

The biggest advantage of this proposed grid concept is its scalability. To provide more power Astrobotic need only send more panels to a location. The more the merrier. And all can be built in an assembly-line manner, thus making construction very cheap and efficient.

Webb instrument has technical issue partly preventing its use

Because a an issue with the mid-infrared instrument (MIRI) on the James Webb Space Telescope, the telescope’s engineering team has paused use of that instrument while it reviews the situation.

On Aug. 24, a mechanism that supports one of these modes, known as medium-resolution spectroscopy (MRS), exhibited what appears to be increased friction during setup for a science observation. This mechanism is a grating wheel that allows scientists to select between short, medium, and longer wavelengths when making observations using the MRS mode. Following preliminary health checks and investigations into the issue, an anomaly review board was convened Sept. 6 to assess the best path forward.

The Webb team has paused in scheduling observations using this particular observing mode while they continue to analyze its behavior and are currently developing strategies to resume MRS observations as soon as possible. The observatory is in good health, and MIRI’s other three observing modes – imaging, low-resolution spectroscopy, and coronagraphy – are operating normally and remain available for science observations.

I am quoting almost entirely NASA’s short announcement. The announcement is vague, confusing, and (quite typically) written to minimize the reality of the issue. I can’t figure out how MIRI’s other observing modes are available if they have paused use of a mechanism that allows them to choose modes.

Regardless, Webb is awful young to have this kind of problem.

SpaceX fires seven engines on Superheavy prototype #7

Capitalism in space: SpaceX today successfully did a static fire engine test of seven engines on its Superheavy prototype #7, intended to be the lower stage of the first Superheavy/Starship orbital test.

The link takes you to the full live stream. Below I have cued that live stream to just before the test occurred. Everything seems to go as planned, with no obvious anomalies.

SpaceX continues to be moving closer and closer to that first orbital flight.

Interstellar clouds backlit by nearby massive star

Interstellar clouds backlit by nearby massive star
Click for full image.

Cool image time! The photo to the right, cropped and reduce to post here, was taken by the Hubble Space Telescope of what astronomers believe is a newly formed massive star about 9,000 light years away that has periodically spewed out material during eruptions.

The scientists hope to use Hubble to determine the speed in which this material is flying away from the star by taking pictures at intervals and then measuring the amount of change from image to image. This data will also allow the scientists to better gauge the distance to this star, as well as its actual mass, information that will help them better understand what is happening.

I highlight this picture however simply because of its beauty. The interstellar clouds on the left are all apparently backlit by the brightest star on the right, and thus their shape is easy to perceive.

InSight’s seismometer detects its first new impact on Mars

Martian impact discovered by InSight
Click for full image.

Using data from InSight’s seismometer that suggested a new impact had occurred at a specific location on September 5, 2022 on Mars, scientists used the high resolution camera on Mars Reconnaissance Orbiter (MRO) to search and find that impact.

The photo to the right, reduced to post here, is that MRO photo.

The initial impact itself created a small marsquake that was detected by InSight’s seismometer. The instrument recorded seismological data that showed the moment the meteoroid entered Mars’ atmosphere, its explosion into pieces in the atmosphere, and finally, the impact that created a series of at least three craters in the surface.

MRO then flew over the approximate site where the impact was “felt” to look for darkened patches of ground using its Context Camera. After finding this location, HiRISE captured the scene in color. The ground is not actually blue; this enhanced-color image highlights certain hues in the scene to make details more visible to the human eye – in this case, dust and soil disturbed by the impact.

This was thus the first new Martian impact detected based on its actual occurrence, rather than simply finding a change between two photos taken at different times. The latter only tells you a time period when the impact occurred. InSight’s detection here marks the impact’s exact moment.

Nor is this the only such discovery. It appears that InSight detected at least two other impacts (here and here), that only subsequently were linked to MRO impacts. In those cases, the new impact had already been found by MRO, and only afterward were scientists able to identify its seismic vibration in InSight data, thus pinpointing the exact date it took place.

Orbital tug company signs launch agreement with German rocket startup

Capitalism in space: The orbital tug company Spaceflight today signed a launch agreement with the German rocket startup Rocket Factory Augsburg (RFA).

The agreement formalizes the plan for Spaceflight to fly its Sherpa® orbital transfer vehicles (OTVs) and other rideshare payloads on upcoming RFA missions from a variety of European launch sites, including from facilities in the United Kingdom, French Guiana and others. The companies are targeting mid-2024 for their first launch.

Rocket Factory is one of three German startup rocket companies pushing to complete the first German commercial launch. While Isar Aerospace had raised the most capital, it remains unclear which of these companies will win.

Valeri Polykov, holder of the record’s longest stay in space, passes away

Valeri Polykov
Valeri Polykov

Russian astronaut Valeri Polykov, who holds the record for the longest spaceflight yet of any human in history, has passed away at the age of 80.

In 1994 and 1995 Polykov spent 437 days on Russia’s space station Mir, the equivalent of fourteen months and two weeks. His thoughts at launch, as he told me personally when I interviewed him while writing Leaving Earth, were not so confident:

“What if something goes wrong?” [he explained]. “I had sacrificed so much time. The government has spent so much, more than they can afford. And I’ve learned so much for them myself, for them.

“Better I die if something went wrong,” he thought. “Better if I had a gun to shoot myself.”

Nothing went wrong however. Polykov, a doctor, had pushed for this long mission to find out if it would be possible for a person to function after a year-plus of weightlessness upon arrival on Mars. Originally planned to last 18 months, circumstances eventually shortened it to 14 months-plus. When Polykov came home in March 1995, he managed to walk a few steps on his own, shortly after being removed from the capsule. To his mind, he had proved that a person could function on their own on Mars after such a long flight.

Others disagreed. As I wrote in Leaving Earth, though he was almost normal within a week of landing,

Polykov had come back to Earth very weak. For at least those first few hours, he needed help from those around him. Any spacefarer arriving on Mars after a year in space must be prepared to face that same challenge.

Regardless, Polykov, like Brian Binnie, was one of the early giants in space exploration. His contribution must not be forgotten.

SpaceShipOne pilot Brian Binnie passes away

R.I.P. Brian Binnie, who piloted SpaceShipOne on its second flight that won the Ansari X-Prize back in 2004, passed away on September 15, 2022 at the age of 69.

Brian’s record flight was the second of two SpaceShipOne flights needed to win the $10 million Ansari X Prize. The prize was given for the first privately-built crewed vehicle to make a flight above 100 km (62.1 miles) twice within two weeks. Mike Melvill made the first flight for the Ansari X Prize competition five days earlier.

The success of this private spaceship proved that private enterprise could do better than government, if given the chance. It laid the groundwork for the renaissance in American rocketry we are seeing today.

His part in this history must not be forgotten.

Webb takes its first infrared image of Mars

Webb's first infrared image of Mars
Click for full image.

Astronomers have now released the the James Webb Space Telescope’s first infrared image of Mars, taken on September 5, 2022.

The image to the right, cropped and reduced to post here, shows some of the data obtained. Because Mars is so close, it is actually too bright for Webb’s instruments. To get any data, the exposures were very very short, and still the brightest areas — as indicated by large areas of yellow — are overexposed. The cause of the different brightness of Hellas Basin, however, is not simply because the basin — the deepest point on Mars — is cooler.

As light emitted by the planet passes through Mars’ atmosphere, some gets absorbed by carbon dioxide (CO2) molecules. The Hellas Basin – which is the largest well-preserved impact structure on Mars, spanning more than 1,200 miles (2,000 kilometers) – appears darker than the surroundings because of this effect. “This is actually not a thermal effect at Hellas,” explained the principal investigator, Geronimo Villanueva of NASA’s Goddard Space Flight Center, who designed these Webb observations. “The Hellas Basin is a lower altitude, and thus experiences higher air pressure. That higher pressure leads to a suppression of the thermal emission at this particular wavelength range [4.1-4.4 microns] due to an effect called pressure broadening. It will be very interesting to tease apart these competing effects in these data.”

The NASA press release says the scientists are preparing a paper analyzing the spectral data and what it revealed about “dust, icy clouds, what kind of rocks are on the planet’s surface, and the composition of the atmosphere,” I suspect however that Webb’s capabilities for studying Mars are much more limited than implied, and that it will over time take much fewer images of the red planet, compared to Hubble.

SpaceX launches 54 Starlink satellites on Falcon 9

After four scrubs on four consecutive days, SpaceX tonight finally successfully put 54 Starlink satellites into orbit.

The first stage successfully completed its sixth flight, landing on a drone ship in the Atlantic. The fairings halves completed the third and fourth flights, respectively.

The leaders in the 2022 launch race:

42 SpaceX
37 China
11 Russia
7 Rocket Lab
5 ULA

American private enterprise now leads China 58 to 37 in the national rankings, and the entire globe 58 to 56. At 58 successful launches, 2022 is now the third most active year in the entire history of the United States, with only 1965 and 1966 having more launches.

This post is late because I spend the weekend in the mountains, caving. Twas a much needed break.

SpaceX now offers more expensive high performance Starlink for residential customers

SpaceX has now made available the much more expensive Starlink high performance terminals — previously only available to business customers — for its residential customers.

The purchase price for the terminal is the same as for business customers, $2,500. The standard terminal package costs only $599. However, residential customers who buy this more expensive terminal will still pay the standard $110 month rate for the service, instead of the $500 monthly fee that business customers will pay.

SpaceX notes that the high-performance Starlink kit would be best for users who reside in harsh environments, such as those who are in hot or cold climates. Starlink’s Support Page also indicates that the high-performance dish has better download speeds in hot weather, better snow melt capability, improved water resistance, and better visibility of satellites.

I would expect that eventually, when SpaceX is faced with competition in this market, these features will end up on all its terminals. Until then, however, new customers will have to make a choice.

ABL completes dress rehearsal countdown for its first RS1 rocket launch

Capitalism in space: The smallsat rocket company ABL successfully completed a full dress rehearsal countdown for its first RS1 rocket this past week, and is presently negotiating with the FAA the launch date for that rocket’s first test launch.

Though ABL is its own independent company, one of its biggest investors has been Lockheed Martin. In fact, in almost all ways, ABL is a Lockheed Martin division, and appears to be part of the older and bigger company’s strategy for entering the smallsat market.

Cool image time! Today we return to the Athabasca Valles flood lava event, believed to be the youngest major lava event on Mars that I highlighted in a cool image last week.

Then, I showed two meandering lava flows near the edge of this Great Britain-sized flood lava plain, produced 600 million years ago in only a matter of weeks. Today, we take a look deep within the lava plain. The photo to the right, rotated, cropped, and reduced to post here, was taken on May 6, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what the scientists label “a lava-crater interaction.”

In plain English, we are looking at a crater that has been inundated by the flood lava, filling it.

Starlink being tested in Antarctica

Capitalism in space: The National Science Foundation (NSF) has begun testing a single Starlink terminal at its McMurdo station in Antarctic, with the hope that the service can improve communications at the station significantly.

Everyone at the base shares a 17 Mbps link, according to the United States Antarctic Program, which severely limits what people can do. The station actually blocks people from using high-bandwidth apps like Netflix, cloud backups, and video calls, with the exception of once-weekly Skype or FaceTime sessions at a public kiosk or mission-critical communications.

The addition of Starlink probably doesn’t mean that McMurdo residents will be able to hold a Netflix movie night or anything — the terminals can handle around 50-200 Mbps, which still isn’t a ton to go around, even during the winter when far fewer people are at the base — but it could help make transferring important scientific data off of the icy continent easier.

According to SpaceX’s plans, this new service in Antarctica means that by year’s end Starlink will be available on all seven continents.

CAPSTONE update: Situation improved but not resolved

Advanced Space, the company operating the CAPSTONE smallsat lunar orbiter that is on the way to the Moon, has issued a hopeful update on the efforts to regain full control of the spacecraft after it began tumbling out-of-control on September 8th.

The communications situation has dramatically improved, the power state of the spacecraft appears to be sufficient for continuous (duty cycled) heating of the propulsion system which dropped below its operational temperature, Over the past few days, CAPSTONE’s power – though limited by the orientation of the spacecraft in its spin relative to the Sun – appears to be sufficient for heating of the propulsion system. When the spacecraft propulsion system temps are at +5C for 12+ hours the system will be further evaluated for use in the recovery operation. Information on the cause of the anomaly has been obtained and is being evaluated, and recovery plans that mitigate risk of further anomalous behavior are being developed. We do not have a timeline for a recovery attempt.

It appears they have not yet done the detumble maneuver that the engineers think will bring the spacecraft back to nominal operations. However, the spacecraft appears to also be on its planned course towards the Moon, so all signs suggest a full recovery is likely.

Rocket Lab successfully launches commercial radar satellite

Capitalism in space: Rocket Lab today successfully used its Electron rocket to place a commercial radar Earth observation satellite into orbit.

This was the company’s 30th successful launch. As of this writing, the satellite itself has not yet deployed.

The leaders in the 2022 launch race:

41 SpaceX
37 China
11 Russia
7 Rocket Lab
5 ULA

American private enterprise now leads China 57 to 37 in the national rankings, and the entire world combined 57 to 56. The 57 successful American launches so for this year ties for third place with 1964 and 1967 for launches in a year. The record number of U.S. launches in a single year was 70, in 1966. That record should almost certainly be topped this year.

SpaceX will once again attempt to launch 54 Starlink satellites later tonight, having cancelled several times this week due to weather.

Billionaire wants to build spinning space station for testing artificial gravity

Capitalism in space: Billionaire Jed McCaleb, who earned billions in software and cryptocurrency, has started a company dubbed Vast to develop and build a spinning space station for testing the pros and cons of artificial gravity.

McCaleb is self-financing at the moment, though he hopes to turn his station eventually into a money-making proposition. His company is also right now very small, but he clearly is going for the best in who he is hiring:

Currently, the company has about 20 employees, including Kyle Dedmon, former SpaceX vice president for construction and facilities; Tom Hayford, a systems engineer who has worked for Relativity Space and SpaceX; Molly McCormick, a former SpaceX human factors engineer and Honeybee Robotics program manager; and Colin Smith, a former SpaceX propulsion engineer. In addition, former SpaceX vice president Hans Koenigsmann is advising the company.

This new private space station joins by my count the four other American private space stations now proposed, including Axiom’s station, a partnership led by Sierra Space building Orbital Reef, Nanorack’s Starlab station, and Northrop Grumman’s upgrade station based on its Cygnus freighter.

That’s five private space stations under development in the United States. And there could be others that I have missed.

Overlapping galaxies

Overlapping galaxies, as seen by Hubble
Click for full image.

Cool image time! The picture to the right, cropped and reduced to post here, was taken by astronomers using the Hubble Space Telescope, and captures two galaxies that happen to overlap in their line of sight to Earth.

The two galaxies, which have the uninspiring names SDSS J115331 and LEDA 2073461, lie more than a billion light-years from Earth. Despite appearing to collide in this image, the alignment of the two galaxies is likely just by chance — the two are not actually interacting.

This image was taken as part of the citizen-scientist project dubbed Galaxy Zoo, whereby volunteers review lower resolution images of strange-looking galaxies and propose the best for Hubble higher resolution imaging.

Astronomers propose method for predicting the stars that will go supernovae

The uncertainty of science: Using a computer model based on the most recent data that suggests red supergiant stars like Betelgeuse are the kind of stars that produce certain kinds of supernovae, astronomers now think they have a method for predicting which of those stars are about to go supernovae.

You can read the science paper here. From the link above:

In a few examples, astronomers have looked back at old catalogs and found images of the stars before they exploded, and they all seem to be red supergiants like Betelgeuse. That’s a clear indication that those kinds of stars are supernova candidates, ready to go off at a moment’s notice.

The stars that result in these kinds of supernovas are thought to have dense shrouds of material surrounding them before they explode. These shrouds are orders of magnitude denser than what’s measured around Betelgeuse.

More importantly, the data suggests that once this shroud of material forms, the supernova will follow, in just a few years. As the scientists conclude in their paper:

The final overarching conclusion we can make from this work is that, shortly before core-collapse, [red supergiants] must undergo some prodigious mass-losing event which radically alters the appearance of the star. Therefore, the signature of an imminent explosion should be a dramatic change in the progenitor stars’ optical – near-IR photometry on timescales of less than a month. Such a signature should be detectable in the coming era of wide-field short cadence photometry. [emphasis mine]

Near-IR (infrared) photometry is exactly in the wavelengths in which the James Webb Space Telescope operates. Thus, if it is lucky and sees this kind of star in an image, and a supernova follows shortly thereafter, this theory will have been proven correct.

Company providing satellite engines for smallsats raises $28 million

Capitalism in space: Morpheus, a German company focused on providing small satellites engines for maneuver and de-orbit, has successfully raised $28 million in private investment capital.

Morpheus, a company originally focused on producing miniature electric thrusters, has broadened the scope of its business to offer propulsion systems and software to help satellites maneuver in orbit and deorbit at the conclusion of their missions.

Last year, Morpheus unveiled a suite of products designed to reduce the cost and complexity of operating satellite constellations. The Sphere Ecosystem includes thrusters with nontoxic propellant, plug-and-play autopilot, space mission software and a web application.

This is not the only German company moving into the new space market. Three startup rocket companies have all successfully raised capital. Morpheus’s success, along with those rocket companies, suggests that Germany is quickly transitioning from a government-run space industry to a privately-run one.
