Dragon cargo launch now delayed until July to fix fuel leak

9:32 am

Capitalism in space: Having now identified the source of a toxic hydrazine fuel leak in a Dragon cargo capsule that had been scheduled for launch on June 10th, SpaceX has now delayed the launch until July 11th so that it can fix the leak.

After removing propellant from the vehicle, “SpaceX was able to narrow down the source of the issue to a Draco thruster valve inlet joint,” the agency said. “Teams will now remove the specific hardware to replace it ahead of flight.”

Based on standard SpaceX procedures, it will not only replace this one valve, it will carefully figure out why it failed, and introduce an upgrade to all such valves so that this leak issue is never repeated. Such a policy has generally not been followed with much enthusiasm by older rocket companies in the past half century. The result had been the reappearance of such problems again and again, instead of a slow decline as each was found and eliminated.

Sierra Space developing crewed version of Dream Chaser; will train astronauts

9:24 am

Capitalism in space: In a press release mostly focused on touting the company’s new project to establish a training center for astronauts, Sierra Space dropped this bigger story:

A crewed variant of the Dream Chaser spaceplane is currently in development and will be operational in 2026, having successfully completed its System Requirements Review (SRR) earlier this month. Orbital Reef will be on orbit and operational in 2027.

Though it was always expected that the company would upgrade the cargo version of Dream Chaser it is presently building, until now it had been made no announcement to that effect. Moreover, until now Sierra Space has functioned much like the old big space companies, doing nothing without a contract from NASA. This effort to build a manned version of Dream Chaser is apparently occurring without any such contract. All Sierra has right now is a contract to launch cargo to ISS.

The astronaut training center fits in nicely with this new manned Dream Chaser, which also fits in nicely with Sierra Space’s partnership to build the commercial space station Orbital Reef.

Ingenuity successfully completes its 29th flight on Mars

3:51 pm

Ingenuity's 29th flight, estimated

Based on this tweet posted yesterday, Ingenuity has successfully completed its 29th flight on Mars, placing it in “a better communication position with the rover.”

According to the helicopter’s flight log, the flight lasted about 66 seconds, was about 587 feet long, and had a maximum altitude of 33 feet.

On the overview map to the right the green dot marks Ingenuity’s position before the flight. The yellow line is my guess as to the approximate flight path for this 29th flight. In this new position the helicopter is better aligned with the hollow that Perseverance will climb (as indicated by the red dotted line), and will therefore also have better line of sight communications with it.

The flight itself tells us that the engineers have not only gotten the helicopter recharged, they have developed new flight software to compensate for the loss of a sensor that was used to determine Ingenuity’s elevation.

Momentus concedes its Vigoride tug will probably not be able to deploy more satellites

9:32 am

Capitalism in space: Momentus yesterday conceded that because of the problems that have dogged the first flight of its Vigoride tug, it will probably not be able to deploy the remaining smallsats on board.

Previously the company had said that communications issues were interfering with deployment. This update revealed that the tug’s solar arrays had also not opened as intended.

After initially experiencing these anomalies, we were able to deploy two customer satellites from Vigoride on May 28. Since that time, we have continued efforts to deploy other customer satellites, but have not confirmed any subsequent deployments. While we previously established two-way communications with the Vigoride vehicle, we have not been able to continue such two-way communication, which we believe is due to the low power situation on the vehicle due to the deployable solar arrays not operating as intended.

Though this update is very unclear on this point, it appears that Vigoride was able to deploy three objects in total, or a total of six smallsats. How many additional smallsats failed to deploy is not clear.

The company plans its next launch in November, with additional launches next year.

Test of solar sail for de-orbiting smallsat ends successfully

9:22 am

Capitalism in space: The Canadian company Space Flight Labs announced yesterday that its first test of a solar sail for de-orbiting a small satellite ended successfully last month.

The CanX-7 (Canadian Advanced Nanospace eXperiment-7) was a three-kilogram, 10x10x34cm satellite that was launched on September 26, 2016. The satellite was funded by the Defence Research and Development Canada, the Natural Sciences and Engineering Research Council, COM DEV Ltd. (now Honeywell), and the Canadian Space Agency.

According to SFL [Space Flight Labs] “the satellite successfully completed a seven-month aircraft tracking campaign before deploying its drag sails in May 2017 to demonstrate drag-sail based deorbiting.” SFL said it took five years for the drag sail to deorbit the satellite and without it the satellite wouldn’t have burned up in the atmosphere for roughly another 178 year.

When the four drag sails, each about one square meter in size, were deployed, engineers immediately measured an increase in the orbital decay rate. Though it still took five years to force a de-orbit, the system removed the satellite from orbit much sooner than otherwise.

The system is aimed at the smallsat market, satellites too small for other proposed removal methods that also might remain stranded in orbit for a very long time because of their small size.

FAA finally releases its environmental reassessment of SpaceX’s Boca Chica facility

11:44 am

SpaceX's plan of operations at Boca Chica

After almost a half year of delays, the Federal Aviation Administration (FAA) today released its environmental reassessment of SpaceX’s operations in Boca Chica, Texas, possibly recommending that future launches of Starship/Superheavy be allowed at that location but also leaving open the continuing ability of the federal government to block further flight tests.

The FAA determined that the Proposed Action would not result in significant environmental consequences and has issued a Mitigated Finding of No Significant Impact/Record of Decision (FONSI/ROD). … Required mitigation measures are listed throughout Chapter 3 of the final PEA [the environmental reassessment]. Should any future license or permit be issued to SpaceX to perform any aspect of the Proposed Action, the FAA will ensure that SpaceX implements these mitigation measures as conditions for licensure.

You can read the executive summary here [pdf]. The actual reassessment [referred to as the PEA] can be read here [pdf]. The key quote, on page 2 of the reassessment, is this:

The applicant has provided the FAA with a mission profile of proposed launch operations that is
analyzed in this PEA. The FAA’s Federal Action is to issue experimental permit(s) and/or a vehicle operator license to SpaceX for this mission profile, which is described in more detail in Section 2.1. If SpaceX modifies or adds operations as part of its Starship/Super Heavy program in the future, the FAA would analyze the environmental impacts of those activities in a tiered environmental document, which would summarize the issues discussed in this PEA that remain applicable (e.g., the environment around the Boca Chica launch site) and concentrate on the issues specific to the subsequent action (e.g., a mission profile involving a new landing site).

The completion of the environmental review process does not guarantee that the FAA will issue an experimental permit or vehicle operator license to SpaceX for Starship/Super Heavy launches at the launch site. [emphasis mine]

Essentially, SpaceX — after some revisions based on public comments — provided the FAA a detailed outline of its proposed operations, as summarized by the graph above (taken from the executive summary), and the FAA agreed to that program. However, this agreement by the FAA does not include any actual permits for flights or tests.

Furthermore, this recommendation by the FAA is not final. The reassessment also included in great detail a second option, dubbed the “No Action Alternative”:

Under the No Action Alternative, the FAA would not issue new experimental permits or licenses to SpaceX for any test or launch operations at the Boca Chica Launch Site. In this situation, SpaceX’s production and manufacturing that that do not require a license from the FAA or approval by any other federal agencies would continue at its existing facilities and production and manufacturing infrastructure would expand. Testing operations, including tank tests and static fire engine tests, that do not require approval by the FAA or other federal agencies would also continue at the VLA. In addition, SpaceX could conduct missions of the Starship prototype launch vehicle as authorized by the current license (LRLO 20‐119). 6 The license expires on May 27, 2023. This alternative provides the basis for comparing the environmental consequences of the Proposed Action.

Under this alternative, SpaceX operations at Boca Chica would be severely limited, and would essentially end in May ’23.

In reviewing both documents, it appears that the FAA has given SpaceX a go-ahead with this reassessment, but done so with many caveats. It will issue SpaceX its launch permits, probably on a per launch basis, each of which will require SpaceX to meet more than 130 pages of further environmental and social justice requirements. As noted in the first quote above, should SpaceX fail to meet any of those mitigation measures, future permits will be blocked.

Furthermore, the reassessment appears to have left it open for the White House to choose the “No Action Alternative.”

In either case this reassessment appears to have given any number of agencies within the federal government — including the White House — the clear ability to block SpaceX’s operations repeatedly, after each test flight.

I suspect SpaceX will immediately apply for a launch permit, and hope that political pressure will force the federal agencies to approve that permit.

NOTE: This analysis is based on a first quick review. The documents are long and purposely written to make it hard to figure out what is being proposed. More review is still required.

Perseverance's first cliff
Click for full image.

Time for some cool images from Perseverance! The rover, now on Mars for more than a year, has finally begun its journey up the delta of material that some time in the past flowed through a gap in the rim of Jezero Crater. In doing so, it has also finally got close to a nearby cliff, within fifty feet or so, and used its high resolution left mast camera (mastcam) to take the photos to the right. The first, cropped and reduced to post here, was a wider shot taken on June 10, 2022, with the red arrow pointing to the part of the cliff featured in the second image below, taken on June 12, 2022, after the rover had moved in closer. This second photo is also cropped and reduced to post here.

Astra launch a failure when upper stage shuts down prematurely

11:09 am

Capitalism in space: A launch attempt today by Astra of two NASA weather cubesats, designed to study the evolution of storms in the tropics, was a failure when the upper stage engine shut down prematurely.

This was the second launch failure for Astra out of three launch attempts in 2022. Both this failure and the February 10th failure occurred after the first stage has successfully done its job. The first was due to the failure of the fairings to separate. Today the fairing ejected properly, but then the second stage engine failed.

The launch however did illustrate something quite profound. Though it occurred about one hour and forty-three minutes into its two hour launch window, the launch team was able to recycle the count three times due to various issues and still launch. What makes this significant is that such quick countdown recycles have now become very routine.

When SpaceX did its first quick countdown recycle back during its first Falcon-1 launches in the 2000s it was astonishing, as NASA would never do such a thing. If a NASA shuttle launch aborted close to launch, the agency would always stand down for at least a day to figure things out. Even today, its ability to do a quick countdown recycle with its SLS rocket is almost impossible, as shown during its first attempt to do a dress rehearsal countdown of SLS in April. With each abort the agency had to reschedule for the next day or even later. It had little ability to quickly turn things around.

Private enterprise has since proven that such slow operations are inefficient and unnecessary.

Meanwhile, Astra needs to fix this issue and launch again. It was able to investigate and fix the fairing issue that caused that February launch failure in just over a month. Hopefully it can do the same again.

Russia proposes restart of ExoMars partnership with ESA

8:17 am

Russia’s aerospace corporation Roscosmos has proposed to the European Space Agency (ESA) that its partnership to launch and land ESA’s Franklin rover on Mars be renewed, despite the Ukraine War and Roscosmos’ confiscation of 36 OneWeb satellites.

[According to Roscosmos head Dmitry Rogozin] the equipment and Kazachok landing platform for the mission have the potential for launch in 2024. “ESA colleagues promised to make requests to their patrons, who are ESA member states. If they cooperate and give their consent, the mission may be implemented,” Rogozin said.

He estimates the likelihood of this scenario to be at about 708%. [sic] Roscosmos plans to get the response in late June. [emphasis mine]

It would not be surprising if ESA made this deal, despite its stupidity. Roscosmos’ actions recently, especially related to OneWeb, prove the people running it are very untrustworthy business partners. Yet Europe’s historic willingness to deal with the devil for short term gain — eventually and repeatedly leading to overall disaster — is legendary.

Momentus’s space tug successfully deploys two smallsats, despite communications issue

8:21 pm

Capitalism in space: In a brief update released on May 31st, Momentus announced that despite the communications issues engineers are having with the communications system on its Vigoride space tug, it was still able to successfully deploy two smallsats several days earlier.

The update also says that the company plans “… to continue work to address the anomalies on the Vigoride spacecraft announced on May 27 and deploy additional customer satellites.”

Based on these updates, as well as the company’s description of this mission, it is not clear how many other smallsats still need to be deployed.

Russian government gives Roscosmos permission to negotiate astronaut barter deal

8:00 pm

The Russian prime minister yesterday signed a decree giving Roscosmos permission to negotiate a astronaut exchange deal with NASA, whereby for every American that flies on a Soyuz to ISS one Russian would fly on either a Dragon or Starliner capsule.

NASA has been pushing for this arrangement for about a year, but Russia was at first skittish about flying on Dragon. Then its invasion of the Ukraine raised further barriers. Now that it is clear the Russians have no options in space but to stick with ISS for at least the next few years, the Russian government has relented and will allow this barter arrangement to go forward.

NASA had been pushing to put the first Russian on a Dragon in the fall. That flight is now likely to happen.

Of course, all this could change should things change drastically in the Ukraine. The partnership on ISS remains quite fragile politically, even if the astronauts and engineers and workers of both sides continue to work together well.

Dusty Gale Crater in the winter

Cool image time! The panorama above, created from five images taken by Curiosity’s left navigation camera on May 25, 2022, looks north across the floor of Gale Crater at its rim about 25 miles away.

The butte on the left I think (though I am not certain) is the backside of the same butte seen from the front in December 2021. Then, Curiosity was below it looking up. Now, Curiosity is above it looking down.

For scale, that butte is about ten feet high. Navarro Mountain on the right is about 450 feet high, but looks less impressive because it is farther away.

It is now winter in Gale Crater, a time period when there is more dust in the atmosphere. This fact becomes very evident if you compare this panorama with a similar one taken in December 2021 in the Martian fall. Then, the air is crystal clear, and the rim can be seen in great detail. Now, though visible (barely) on the left, the haze makes the more distant peaks on the right almost invisible.

Curiosity has climbed about 1,750 feet since it landed in 2012. It is still about 12,600 feet below the peak of Mount Sharp. The blue dot and yellow lines in the overview map to the right indicates Curiosity’s location when the panorama was taken, and the approximate area covered by it.

Be sure and look at the full resolution panorama, especially the section near the middle, where the dramatic nature of this terrain is most evident.

Stratolaunch test flight of Roc ends prematurely

9:25 am

Capitalism in space: A recent Stratolaunch test flight of its giant carrier airplane Roc was ended prematurely because engineers had detected an unexpected “test result”.

“While completing Roc testing operations, we encountered a test result that made it clear we would not achieve all objectives for this flight,” the California-based company, which was created by Microsoft co-founder Paul Allen more than a decade ago, said in Twitter update. “We made the decision to land, review the data, and prepare for our next flight.”

The company has provided little additional information. The flight itself was planned to last as much as 3.5 hours, but only lasted about an hour and a half.

Stratolaunch’s present plan is to offer Roc and its Talon-A payload as a testbed for testing hypersonic flight.

Delay in Psyche launch wrecks smallsat asteroid mission

9:18 am

The two month delay in the launch of NASA’s Psyche asteroid mission because of software issues has apparently wrecked a smallsat asteroid mission that was to launch as a secondary payload on the Falcon Heavy rocket.

Janus, a NASA smallsat mission selected in 2019, will launch two identical spacecraft as secondary payloads on the Falcon Heavy rocket whose primary payload is Psyche. After a series of Earth flybys, each Janus spacecraft was to fly by different binary asteroids, designated 1996 FG3 and 1991 VH.

However, the mission’s principal investigator said June 8 that mission plan is no longer possible. Speaking at a meeting of NASA’s Small Bodies Assessment Group (SBAG), Dan Scheeres of the University of Colorado noted that mission plan assumed Psyche launched in August of this year as previously planned. NASA announced May 23 that the mission’s launch had been delayed to no earlier than Sept. 20 to provide more time for testing the spacecraft’s software.

With the revised launch date, he said it’s no longer possible for the spacecraft to perform those Earth flybys with the existing spacecraft design. “Those flybys were essential for setting up our flybys of our target binaries, 1991 VH and 1996 FG3,” he said.

The Janus team are right now scrambling to see if they can find other asteroids the spacecraft can reach, based on the new launch date. Their work however is badly hampered by the uncertainty of that date, which could still change for many reasons.

The heart of the problem, as Scheeres notes, is its status as a secondary payload.

“We have no ability to influence the launch dates or the targeting of the launch vehicle, and that arises from our status as a rideshare,” he said.

The article also describes two other NASA interplanetary smallsat missions that have been badly hindered because of their status as secondary payloads. All three stories strongly suggest that in the future it will make much more sense to put such missions on its own rocket, as the primary payload. This is what NASA did with its CAPSTONE smallsat mission to the Moon, which will launch on a Rocket Lab Electron rocket sometime before the end of the month.

Update on Starship in Texas and Florida

9:01 am

Link here. The article goes into great detail describing the status of the Superheavy booster prototype and the Starship prototype now planned for that first orbital launch, with this comment:

While some claim FAA is the hold up for Starship plans [I wonder who], even if the FAA had approved a launch in December of last year, SpaceX likely still would not have been ready for an orbital launch.

Maybe so, but why do journalists today have to bend over backwards making believe the federal government is not a problem, or is not interfering with this private company’s operations? It clearly is a problem, and is interfering with private companies, and it is doing so more and more for political reasons. Good reporting must note this.

The report also provides details on the status of SpaceX’s Florida Starship orbital launchpad. The company only began serious construction in Florida in April, yet large sections of the launch tower as well as its foundation have already been built. The pace of construction — as well as SpaceX’s past history building the Boca Chica launchpad — suggests this launchpad could be ready before the end of the year.

Compare that with NASA’s incompetent effort to build its SLS mobile launchers. The contrast is striking.

SLS’s 2nd mobile launcher to cost more than $1.5 billion, 3x what was initially budgeted

11:47 am

SLS's two mobile launchers, costing $1 billion
NASA’s bloated SLS mobile launchers

According to an inspector general report [pdf] released today, the second mobile launcher being built by the company Bechtel to transport its SLS rocket from the assembly building to the launch site is likely going to cost more than $1.5 billion, three times what was initially budgeted, and will not be completed any earlier than the end of 2027, four years behind schedule.

Compounding Bechtel’s projected cost increases and schedule delays, an ML-2 [mobile launcher-2] project analysis provided only a 3.9 percent confidence level that the nearly $1 billion cost [twice the original budget] and October 2025 [2.5 years late] delivery estimates were accurate. NASA requires projects to develop budgets and schedules consistent with a 70 percent joint cost and schedule confidence level (JCL), meaning a 70 percent likelihood the project will finish equal to or less than the planned costs and schedule. In fact, an Independent Review Team analysis determined the project would require an additional $447 million and 27 months, for a total contract value of $1.5 billion and a launcher delivery date of December 2027—a schedule that would enable an Artemis IV launch no earlier than the end of 2028.

The first mobile launcher, shown on the left in the graphic, cost more than $1 billion and will used only three times, at most. The second, on the right, is required for all of the assigned interplanetary tasks being given to the full size version of SLS beyond those first three test flights. Without it that version of SLS cannot launch. And even if the launcher is ready by 2028, as the IG report suggests, that will be more than a decade behind schedule, and six years from now.

Amino acids found in asteroid samples brought back from Ryugu

10:01 am

Japanese scientists revealed this week that they have detected more than 20 types of amino acids in the asteroid samples brought back from Ryugu by the probe Hayabusa-2.

Kensei Kobayashi, professor emeritus of astrobiology at Yokohama National University, said the unprecedented discovery of multiple types of amino acids on an extraterrestrial body could even hint at the existence of life outside of Earth. “Proving amino acids exist in the subsurface of asteroids increases the likelihood that the compounds arrived on Earth from space,” he said.

It also means amino acids can likely be found on other planets and natural satellites, hinting that “life could have been born in more places in the universe than previously thought,” Kobayashi added.

Let me emphasize that this is not a discovery of life on Ryugu, only chemistry that is found in life on Earth. Such chemistry however can be found outside of life as well. What this detection suggests however that it is relatively common to produce such complex chemistry in hostile space environments, which increases greatly the possibility of life everywhere in the universe.

Progress in completing the deployment of one of Lucy’s solar panels

9:45 am

Lucy solar panel graphic
Artist’s impression of solar panel

In the past month engineers for the Lucy asteroid mission have conducted a series of successful short tests to see if they can complete the unfolding of one of the probe’s two large solar panels.

On May 9, the team commanded the spacecraft to operate the array’s deployment motor using both the primary and back-up motor windings simultaneously to generate more torque, i.e. a harder pull. The motor operated as expected, further reeling in the lanyard that pulls the solar array open. After running the motor for a series of short intervals to avoid overheating, the team paused to analyze the results. Data from the spacecraft showed that the deployment was proceeding similarly to engineering ground tests, allowing the team to move forward with the second stage of the attempt. Analysis of the data also suggested that there was still additional lanyard to be retracted. The team sent the same commands again on May 12. Although this series of commands did not latch the solar array fully open, it did advance the deployment enough to increase the tension that stabilizes the arrays as was hoped.

On May 26, the spacecraft was again commanded to deploy the solar array. As in the first two attempts, both motor windings were operated simultaneously for short periods of time to avoid overheating. Afterwards the team again analyzed the data from the event, which again showed that the array was continuing to open. The team repeated the deployment command sequence a fourth time on June 2. While the array still did not latch, the data indicates that it continued to further deploy and stiffen throughout the attempt.

The graphic above illustrates the problem. The engineers will attempt further windings, and still hope the panel will open entirely and latch. If not, the stiffening suggests the panel will still stabilize in this open position, which up to now has been sufficient to produce about 90% of the power predicted and enough to complete the mission.

Vulcan likely delayed until ’23

9:35 am

According to Eric Berger at Ars Technica, continuing delays with both the rocket’s payload and main engines, ULA’s Vulcan rocket will almost certainly not launch before the end of this year, as hoped by the company.

The rocket’s first stage BE-4 engines are being built by Blue Origin, and are already four years behind schedule. According to Berger’s sources, they will not be delivered to ULA until mid-August, which makes a launch in ’22 very unlikely, especially because both the engines and rocket are new, and will need time for fitting and further testing as a unit.

As for the payload, Berger’s assessment is not based on any new information. The payload, Astrobotic’s first lunar lander dubbed Peregrine, has also been experiencing delays, but the article provides no further information on whether it will miss its targets to be ready in ’22.

Regardless, it appears that Blue Origin is still dragging in its effort to build the BE-4 engine. If Vulcan cannot launch this year, it will threaten ULA’s long term future, since the company is depending on it to replace its Atlas-5 and Delta rockets. The delays now are allowing others to catch up and grab business that ULA might have garnered had Vulcan been operational as planned.

Webb gets its first large micrometeoroid impact

9:18 am

In a carefully worded press release this week, NASA revealed that one segment of the primary mirror of the James Webb Space Telescope had been hit by a micrometeoroid.

Between May 23 and 25, NASA’s James Webb Space Telescope sustained an impact to one of its primary mirror segments. After initial assessments, the team found the telescope is still performing at a level that exceeds all mission requirements despite a marginally detectable effect in the data. Thorough analysis and measurements are ongoing. Impacts will continue to occur throughout the entirety of Webb’s lifetime in space; such events were anticipated when building and testing the mirror on the ground.

The reason such events were expected is because — unlike most telescopes (including Hubble) — Webb’s mirrors are not enclosed in a tube for protection. To do so would have made the telescope far too expensive to build or launch.

After describing in great detail all the work done prior to launch to anticipate such hits and deal with them, the press release then mentioned this fact almost as an aside:

This most recent impact was larger than was modeled, and beyond what the team could have tested on the ground.

Localized damage to the primary mirror of any telescope is not unusual. With ground-based telescopes such issues are not infrequent and easily worked around. The same applies to Webb. The engineers will calculate how to calibrate this particular segment to minimize distortion from the impact.

However, that the telescope experienced a hit larger than ever modeled, so soon after launch, suggests that those models were wrong, and that larger and more frequent hits can be expected. If so, this could be very worrisome, as over the long run it could shorten the telescope’s life in space significantly.

Close-up on another flaky Martian rock

Cool image time! The picture above, reduced to post here, was taken by Curiosity’s high resolution camera on June 5, 2022 (sol 3494). It shows a close up of another flaky rock near where the rover is presently sitting (the blue dot on the map to the right), similar to the one that I highlighted on May 28, 2022 but zoomed in closer.

Not only can you seen the layered flakes extending out from the rock’s main body, you can see what appear to be small deposits of material between the flakes, as if at one point the material was being placed here by condensation, either from the atmosphere or liquid.

The curvy rounded edges of the rock’s larger flakes could have been caused by the same process, or by long slow wind erosion over the eons since the flakes were formed.

The photo appears to be part of a larger mosaic that the rover’s science team is having the camera take of the strange geology that now surrounds Curiosity. The science team also appears to be continuing its beeline south towards the rover’s original planned route, indicated by the red dotted line on the map. The green dot marks the approximate location of a seasonal recurring dark streak on the cliffside, suggesting some form of seepage, while the white arrows mark a distinct layer that scientists have identified in many places on the flanks of Mount Sharp.

Cool image time! The photo to the right, cropped and reduced to post here, was created from a raw image from the Jupiter orbiter Juno by citizen scientist Sergio Diaz-Ruiz. As he notes in his caption:

Several jet streams at high latitude, near the north pole of the planet, crowned by clouds, contrast with a dark oval just over the center.

The original was taken on February 25, 2022 during Juno’s fortieth close approach to Jupiter. As Diaz-Ruiz notes, the contrast with the dark oval and the higher lighter clouds is striking. It is almost as if thermals rising over that oval are pushing the lighter clouds away.

This is only the fourth Juno image that Diaz-Ruiz has processed. All are quite stunning, and worth a look.

Musk: Starlink will not go public until ’25 at the earliest

9:17 am

Capitalism in space: According to Elon Musk, a public sale of stock for the Starlink internet satellite constellation has now been pushed back another three to four years, and will not occur any earlier ’25.

His revised date means Starlink’s IPO has been delayed once again for another three years. In an email to SpaceX workers in 2019, also obtained by CNBC, Musk gave a three-year timeline for Starlink’s public offering, meaning an IPO could have taken place this year.

In 2020, Musk tweeted that Starlink would “probably IPO” in “several years.” He then tweeted in June 2021 that it would be “at least a few years before Starlink revenue is reasonably predictable” and taking it public any earlier would be “very painful.”

This quote however from Musk I think best describes his experience being in charge of a publicly traded company: “Being public is definitely an invitation to pain.”

Rogozin suggests Russia will stay on ISS till at least ’24

9:10 am

In remarks this past weekend on Russian television, Roscosmos head Dmitry Rogozin said that Russia now plans to continue its international partnership on ISS till at least 2024.

“The ISS will work exactly as long as the Russian side needs to work on it,” Rogozin said. “There are technical problems. The station has been operating beyond its lifespan for a long time. We have a government decision that we are working until 2024.”

…Earlier this year, it was reported by some media outlets that Russia was planning to quit the ISS, blaming Western sanctions, following comments Rogozin made on state television. Rogozin said: “The decision has been taken already, we’re not obliged to talk about it publicly. I can say this only—in accordance with our obligations, we’ll inform our partners about the end of our work on the ISS with a year’s notice.”

The Russian government is presently attempting to develop its own space station for launch before the end of this decade. Since such Russian projects have for decades routinely been delayed, for decades, it is likely that the Putin government has decided that it is better to stay on ISS for the moment then quit and have no space station at all.

Russia has also been negotiating with China to partner with it on China’s space station. While China says it is willing, it also appears entirely uninterested in committing any of its funds to help Russia. It might allow a Russia astronaut to visit its station at some point, but that would likely be the limit of that space station partnership.

All in all, Russia’s space effort faces a dim future. ISS is going to be replaced with several private commercial stations owned by American companies, none of which want to partner with Russia. And Russia doesn’t really have the funds to build its own station. Nor does it have a competitive aerospace industry capable of developing its own stations.

Unless something significant changes soon, Russia’s place in space will shrink considerably in the next ten years.

Russian company S7 ends project to build private rocket

8:50 am

The Russian company S7 has ended its project to build a private rocket, citing lack of funds and a dearth of Russian investors.

Due to a lack of opportunity to raise funding, the project to create a light-class carrier rocket has been suspended,” the press service said.

The company said that was the reason why it let go some of its staff – 30 people out of more than 100 – in June. “Still, S7 Space continues to operate in some areas, such as additive and welding technologies where work is underway,” it said.

S7 first announced this rocket project in 2019. Development was suspended in 2020, however, when the Putin government imposed new much higher fees on the company for storing the ocean launch platform Sea Launch, fees so high that the company was soon negotiating to sell the platform to a Russian state-run corporation.

At the moment it appears that while Russia has possession of the Sea Launch ocean floating launch platform, it has nothing to launch from it. Nor does there appear to be any Russia project that might eventually do so. The Putin government has quite successfully choked off S7 — fearing the competition it would bring to Roscosmos — and with it any other new rocket company.

France signs Artemis Accords

8:35 am

The U.S. State Department yesterday announced that France has become the twentieth nation to sign the Artemis Accords.

The full list of signatories so far: Australia, Bahrain, Brazil, Canada, Columbia, France, Israel, Italy, Japan, Luxembourg, Mexico, New Zealand, Poland, Romania, Singapore, South Korea, the United Kingdom, the United Arab Emirates, the Ukraine, and the United States.

France’s signing is a major breakthrough, as both it and Germany, major players in the European Space Agency, have appeared to resist signing on because to do so would have limited their ability to partner with Russia on space projects (Russia opposes the accords). The Ukraine War has apparently ended France’s resistance. It no longer has any partnerships with Russia, and is not likely to form any new ones in the near future.

We should expect Germany to sign on in the near future as well.

As I wrote in May, the future factions in space are now becoming clearer. On one side we have the American Alliance, signers of the accords who support private property. On the other we have Russia and China, who oppose the accords because they also oppose private property.

In May I also included a third faction, made up of non-aligned space powers. That faction now appears to be fading away, though it still includes Germany and India.

France re-approves Starlink service

8:56 am

Capitalism in space: After finally completing what France’s telecom bureaucracy ARCEP calls “a public consultation,” the French government once again approved Starlink service on June 2nd.

ARCEP had authorized Starlink in February 2021, however, France’s highest administrative court revoked the license April 5 after ruling that the regulator should have first launched a public consultation.

That ruling came after two French environmental activist organizations submitted an appeal to challenge Starlink’s frequency rights, citing concerns including the impact of megaconstellations on views of the night sky and space debris.

This approval, combined with recent approvals of Starlink in the Philippines and Nigeria, continues the steady expansion of Starlink service globally.

Woman arrested for trespassing at SpaceX’s Boca Chica facility

8:45 am

A Pittsburgh woman, Nivea Rose Parker, 20, was arrested on June 1, 2022 while trespassing at SpaceX’s Boca Chica facility.

SpaceX security personnel informed deputies a woman, later identified as Parker, was roaming around the fifth floor of the High Bay #1 building. Parker claimed to be an employee of SpaceX and wanted to speak to Elon Musk, security said. [emphasis mine]

Very little additional information has been made available. However, that Parker could get so far into one building, where rockets are assembled, is quite worrisome, considering the “hate Musk” campaign that is growing on the left. These people willfully riot and bomb facilities. SpaceX must take this trespass as a warning that worst could happen if it doesn’t tighten security at all its facilities, especially Boca Chica.

Fuel leak scrubs launch of Dragon cargo capsule this week

8:52 pm

A fuel leak detected during fueling of hydrazine in a Dragon cargo capsule as it was being prepared for a June 10th launch has forced SpaceX and NASA to delay the launch.

SpaceX detected “elevated vapor readings” of monomethyl hydrazine, or MMH, fuel in an “isolated region” of the Dragon spacecraft’s propulsion system during propellant loading ahead of this week’s launch, NASA said in a statement.

The fueling of the Dragon spacecraft is one of the final steps to prepare the capsule for flight, and typically occurs just before SpaceX moves the craft to the launch pad for integration with its Falcon 9 rocket.

The Dragon spacecraft has propellant tanks containing hydrazine fuel and nitrogen tetroxide oxidizer. The two propellants ignite upon contact with each other, providing an impulse for the cargo ship’s Draco thrusters used for in-orbit maneuvers.

Each Dragon spacecraft has 16 Draco thrusters, small rocket engines that generate about 90 pounds of thrust. The Draco engines are used for orbit adjustment burns and control the spacecraft’s approach to the space station, then fire at the end of the mission for a deorbit burn to guide the capsule back into the atmosphere for re-entry and splashdown.

According to the article, it is not yet confirmed that the leak came from the capsule. If so, however, it could become a more serious issue, especially with the recent story — denied strongly by NASA — that a hydrazine leak caused damage to the heat shield of Endeavour during the return of its Axiom commercial passenger flight.
