Starliner return delayed again to June 26th

In a press briefing today, Boeing and NASA announced that they have decided to delay the return of Boeing’s Starliner capsule, carrying two astronauts, another four days to June 26, 2024. The landing would take place just before dawn, landing at White Sands in New Mexico.

The decision to delay is related to the results from the hot fire tests of the aft thrusters of Starliner on June 15, 2024. Engineers want to review the data, which included finding that one of the eight thrusters is producing unacceptable results and will not be used for the rest of the flight. The other seven thrusters however produced acceptable results, “good thrust” as noted by one official.

The extra time to review the data is also because these thrusters are on the service module, which will not return to Earth. They want to make sure they understand the issues entirely. The longer time docked to ISS is also giving them better data for future longer missions.

As for the helium leaks, the level of leaking appears to be dropping, and in fact dropped after the hot fire burns, and “appears to be somehow related to the thrusters.” Either way, the safety margins remain sufficient so that the return is not threatened in any way by these leaks.

The valve issue also seems under control, with all the valves now working as expected.

Overvall, engineers have decided they have a safe vehicle that can not only be used to return to Earth as scheduled, they are confident that they could also use Starliner as a lifeboat in a sudden emergency.

Surprise! Scientists discover that eating cheese makes you happier in old age!

Science discovers the obvious: A computer analysis of 2.3 million people in Europe has found that eating cheese helped make them healthier and happier as they aged.

A mediation analysis identified 33 factors that mediate “between the well-being spectrum and the aging-GIP” – essentially, statistically, the disease, behaviors and lifestyle choices that significantly reduce the healthy aging score. Key ones included TV watching, smoking, medication use, heart failure, attention-deficit hyperactivity disorder (ADHD), stroke, coronary atherosclerosis and ischemic heart disease.

Cheese, on the other hand, swung the pendulum the other way in both its impact on the well-being spectrum and aging-GIP. One of five key lifestyle mediators the data testing identified, it had a 3.67% positive impact on those healthy aging factors (whereas, for example, higher fruit intake had a 1.96% positive result and too much TV time, an indication of a more sedentary lifestyle, had a 7.39% negative impact on the score for both indicators).

While interesting, this research is generally junk. The number of uncertainties and assumptions are so large that no one should take any of these positive and negative scores very seriously. Furthermore, the study basically discovers something that is patently obvious from the beginning: If you are active and eat well, you will be healthier in old age. If you are a couch potato who smokes, you will likely be sicker in old age.

Why cheese (and fruit) should improve these scores is intriguing, but simply suggests that the study is not very useful. The intriguing (and amusing) nature of these results guarantees however that it will blasted by every mainstream news source in the coming days, with little mention of the weakness of the research.

Once again, the first known binary of two supermassive black holes flares as predicted

The predicted orbit of OJ287

Using a variety of space telescopes astronomers have successfully predicted and then observed a major flare that occurred on November 12, 2021 from OJ287, the first known binary of two supermassive black holes located 3.5 billion light years away at the center of a very active galaxy dubbed a blazar.

On Nov. 12, 2021, TESS detected OJ 287 brightening by about two magnitudes for about 12 hours, as it released as much energy in that short burst as 100 average galaxies would release in the same time. This flare was attributed to a jet from the second black hole; observations from the other telescopes supported that result as well, with Fermi in particular detecting a significant outburst of gamma rays.

The figure to the right comes from the published paper [pdf], and shows the orbit of the smaller supermassive black hole — weighing 150 million solar masses — as it circled the larger central supermassive black hole — weighing 18 billion solar masses — from 2000 to 2021.

This was not the first time such a flare from OJ287 had been predicted and observed. Astronomers also did it in 2019. These observations now strongly confirm the predicted orbit of the small black hole, as shown in the figure.

Rocket Lab gets a new 10-launch contract from Japanese satellite company

Rocket Lab yesterday signed a new 10-launch contract with the Japanese satellite company Synspective, with the launches scheduled for the 2025-2027 timeframe.

Rocket Lab has been Synspective’s sole launch provider since 2020, having already launched four of its satellites, with two other launches already under contract. Thus, the satellite company has bought sixteen total launches from Rocket Lab. Its constellation is designed to provide surface data in any weather condition, using radar.

Conscious Choice cover

Now available in hardback and paperback as well as ebook!

 

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

 
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.

 

“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of founder of the Mars Society.

 

All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount.

The insane mountain slopes of Mars’ deep canyons

Overview map

The insane mountain slopes of Mars' deep canyons
Click for original image.

Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on April 25, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The scientists label this layered deposits, but that hardly describes what we are looking at. This slope, as shown in the overview map above, is the north flank of the central ridgeline inside the giant enclosed canyon depression dubbed Hebes Chasma, located just north of the main canyon of Valles Marineris, the largest known canyon in the solar system.

From floor to peak the ridge is around 16,000 feet high. Yet, its peak sits more than 6,000 feet below the plateau that surrounds Hebes. In this one picture the drop from high to low is only 5,700 feet, with thousands of feet of cliff unseen below and above.

Yet every single foot of these gigantic cliffs is layered. Based on close-up data obtained by Curiosity on the slopes of Mount Sharp in Gale Crater on the other side of the planet, the layers we can see here only represent the most coarse sedimentary boundaries. Within these layers are likely thousands upon thousands of thin additional layers, each likely representing some cyclical climate proces on Mars, even down to individual years.

Note too that the lower slopes in this picture (near the top) suggest some form of erosion flowing downhill. What caused that erosion process however remains unknown. It could have been liquid water, or glaciers, or some other process unique to Mars that we still haven’t uncovered.

Just remember: These obnoxious disturbers of the peace are all Democrats

Lunar Reconnaissance Orbiter snaps picture of Chang’e-6 on far side of the Moon

Chang'e-6's landing site
Click for original image of Chang’e-6 on the Moon

The science team running Lunar Reconnaissance Orbiter (LRO) have now released an image of China’s Chang’e-6 lander on far side of the Moon, taken on June 7, 2024 one week after the spacecraft touched down.

Chang’e 6 landed on 1 June, 2024, and when LRO passed over the landing site almost a week later, it acquired an image showing the Chang’e 6 lander on the rim of an eroded ~50 meter diameter crater.

The LROC team computed the landing site coordinates as 41.6385°S, 206.0148°E, at -5256 meters elevation relative to the average lunar surface, with an estimated horizontal accuracy of plus-or-minus 30 meters.

The overview map to the right, showing the entire far side of the Moon, shows that picture as the inset in the lower left, cropped to post here. The black and white dot in the center is Chang’e-6’s lander, with the surrounding brightened ground showing the blast area produced by the engines during touchdown.

According to the LRO press release, the large dark area that surrounds the lander — as seen in the wider inset in the upper right — is a “basaltic mare deposit” — similar to the vast dark frozen lava seas evident to our own eyes on the near side of the Moon.

Webb produces false color infrared image of the Crab Nebula

The Crab Nebula as in infrared by Webb
Click for original image.

The false-color infrared picture to the right, reduced and sharpened to post here, was taken by the Webb Space Telescope of the Crab Nebula, located 6,500 light years away and created when a star went supernova in 1054 AD, in order to better understand its make-up and origins. From the caption:

The supernova remnant is comprised of several different components, including doubly ionized sulfur (represented in green), warm dust (magenta), and synchrotron emission (blue). Yellow-white mottled filaments within the Crab’s interior represent areas where dust and doubly ionized sulfur coincide.

The spectroscopic data from this infrared observation has in fact increased the puzzle of the Crab’s origin. Previously the data suggested the supernova that caused it was one type of supernova. This data now suggests it could have been a different type, without precluding the possibility of the first.

“Now the Webb data widen the possible interpretations,” said Tea Temim, lead author of the study at Princeton University in New Jersey. “The composition of the gas no longer requires an electron-capture explosion, but could also be explained by a weak iron core-collapse supernova.”

German rocket startup looking for alternatives to Saxavord spaceport

Australian commercial spaceports
Australia’s commercial spaceports. Click for original map.

Because of regulatory delays at the Saxaford spaceport in Great Britain, the German rocket startup Hyimpulse has signed a launch deal with the Australian commercial spaceport Southern Launch.

In May, HyImpulse launched the inaugural flight of its suborbital SR75 rocket from the Southern Launch Koonibba Test Range. The flight had initially been expected to be launched from SaxaVord in Scotland, but delays in the construction of the facility forced the company to look elsewhere for a host.

On 6 June, Southern Launch announced that it had signed a Memorandum of Understanding with HyImpulse for the launch of additional SR75 missions from Koonibba. The agreement also included provisions for the pair to explore the possibility of launching orbital flights aboard the HyImpulse SL1 rocket from Whalers Way Orbital Launch Complex on the south coast of Australia.

According to Hyimpulse’s November 2023 deal with Saxaford, it was to have flown two suborbital flights of the SR75 in 2024 and one orbital flight of SL1 in 2025.

It could very well be that SL1’s first orbital test launch will still take place from Saxavord, but the several years of delays caused by the red tape from the UK’s Civil Aviation Authority in approving Saxavord has forced its customers to seek alternatives. Hyimpulse for example now has agreements not only with Southern Launch in Australia. The French space agency CNES has approved it to launch from French Guiana as well.

In addition, the German rocket startup Isar Aerospace in November 2023 signed a deal with the new Andoya commercial spaceport in Norway. Andoya had come into this spaceport competition very late, but it apparently won this deal because Isar saw the regulatory problems in the UK and decided to look elsewhere.

New evidence suggests some titanium on Boeing and Airbus planes might be fake

According to information provided to the FAA from Boeing, the documentation from a subcontractor for some of the titanium used on some Boeing and Airbus planes might be faked, suggesting that the titanium is fake as well.

Boeing discovered this possibility when one of its suppliers discovered holes in some metal pieces due to corrosion.

Apparently, Italian parts supplier Titanium International Group found small holes in titanium in December 2023, and also raised suspicions about the authenticity of documentation. It notified Spirit AeroSystems of the issue, which in turn informed Airbus and Boeing in January 2024. According to three anonymous sources close to the matter, affected planes include those built between 2019 and 2023 and involve the Boeing 737 MAX, 787 Dreamliner and Airbus A220 programs.

…The problem has been traced back to a Chinese supplier that sold titanium to Turkish company Turkish Aerospace Industries in 2019. Documentation from this Chinese supplier claimed that the titanium had been sourced from another Chinese firm, Baoji Titanium Industry – however, Baoji Titanium has confirmed that it did not provide this batch of titanium “and has no business dealing with this company.” [emphasis in original]

In other words, no one has any idea where that first Chinese supplier got the titanium, because its documentation was false.

Both Airbus and Boeing have done numerous tests and found no problems, though both have said they will remove any suspect parts. Spirit meanwhile has removed all the suspect parts, even though tests suggested the parts were “of sufficient quality for the aerospace industry.”

The real story here is not that these parts are unsafe (they apparently are not). The real story is the dependence by these airplane companies on so many subcontractors, some of which are subcontractors of subcontractors of subcontractors and also come from a hostile power. It leaves them all very vulnerable to others’ mistakes or malfeasance. During the Cold War it would have been inconceivable to rely on Soviet-built parts. Yet, today American airlines routine rely on Chinese companies when the Chinese government has made it clear it sees us as an enemy to be defeated.

Archaeologists discover 35 glass jars at Mount Vernon from 1700s, most containing edible preserved fruits

During an on-going renovation at George Washington’s Mount Vernon home, archaeologists have discovered 35 glass jars from the 1700s, with most containing preserved cherries and berries that appear completely edible.

Of the 35 bottles, 29 are intact and contain perfectly preserved cherries and berries, likely gooseberries or currants. The contents of each bottle have been carefully extracted, are under refrigeration at Mount Vernon, and will undergo scientific analysis. The bottles are slowly drying in the Mount Vernon archaeology lab and will be sent off-site for conservation.

Only a small quantity of the preserved fruits has been analyzed, with the following results:

  • 54 cherry pits and 23 stems have been identified thus far, suggesting that the bottles were likely full of cherries before bottling. Cherry pulp is also present.
  • Microscopy suggests that the cherries may have been harvested by snipping from trees with shears. The stems were neatly cut and purposefully left attached to the fruit before bottling.
  • The cherries likely are of a tart variety, which has a more acidic composition that may have aided in preservation.
  • The cherries are likely candidates for DNA extraction, which could be compared against a database of heirloom varieties to determine the precise species.
  • The pits are undergoing an examination to determine if any are viable for germination.

The last point is most fascinating. Imagine if a new cherry tree could be grown from a pit that was likely picked when George Washington was alive.

Perseverance looks back at downstream Neretva Vallis

Perseverance looks backwards
Click for full resolution version. Highly recommended!

Cool image time! The panorama above was released today by the science team of the Mars rover Perseverance, created from 56 pictures taken by the rover’s high resolution camera. It looks east, downstream into Neretva Vallis, what is believed to be the ancient riverbed that produced the delta that now exists inside Jezero Crater.

The yellow lines in the overview map below indicate the approximate area shown by the panorama. The blue dot marks where Perseverance was located when it took these pictures on May 17, 2024.

Make sure you look at the full resolution image. Neretva Vallis, the depression in the center of the panorama, is about a quarter-mile wide. The green dot on the map marks Ingenuity’s final landing spot. Though the helicopter is somewhere inside that panorama, it does not appear to be visible as it lies on the far side of one of those dunes.

It is also possible that Ingenuity is visible, but is only a tiny dark dot that makes it hard to identify. In reviewing the high resolution image closely, there is one dot that could be Ingenuity.

Space Force names SpaceX, ULA, and Blue Origin as its launch providers for the next five years

As part of the military’s program for issuing launch contracts, the Space Force yesterday announced that it has chosen SpaceX, ULA, and Blue Origin as its launch providers, allowing them to bid on $5.6 billion worth of planned launched over the next five years.

The NSSL Phase 3 program was structured into two “lanes.” Lane 1 is for less demanding launches to low Earth orbit, while Lane 2 is reserved for heavy lift rockets capable of delivering payloads to nine reference orbits, including some of the most demanding national security missions.

The selection of Blue Origin, SpaceX, and ULA for Lane 1 contracts confirms that no other launch providers met the criteria. Seven bids were submitted, according to the DoD announcement.

The Space Force apparently rejected the other four unnamed companies because they “are still maturing their launch capabilities.” It will allow them to re-submit applications next year, and could approve others for bidding at that time, which is a major change from past policy. Previously the military would name approved companies, but not reconsider others for years, a policy that limited its options and reduced competition. Now it appears it will be doing so frequently, possibly every year, in order to regularly increase the number of companies that can bid on military contracts.

This change is excellent news for the American launch industry, as it means the Pentagon has finally ended its long standing launch policy that played favorites.

Voyager-1 now returning science data from all working instruments

Engineers have now resumed full science operations on Voyager-1, presently more 15 billion miles from Earth, after computer issues shut the spacecraft down in November 2023.

The team partially resolved the issue in April when they prompted the spacecraft to begin returning engineering data, which includes information about the health and status of the spacecraft. On May 19, the mission team executed the second step of that repair process and beamed a command to the spacecraft to begin returning science data. Two of the four science instruments returned to their normal operating modes immediately. Two other instruments required some additional work, but now, all four are returning usable science data.

The four instruments study plasma waves, magnetic fields, and particles. Voyager 1 and Voyager 2 are the only spacecraft to directly sample interstellar space, which is the region outside the heliosphere — the protective bubble of magnetic fields and solar wind created by the Sun.

Voyager-2 is 12 billion miles from Earth. Both spacecraft are using what are the longest continously running computers ever built, having been turned on 47 years ago. Both spacecraft however do not have much longer to live, despite the recent fixes. The nuclear power source for both no longer provides enough power to run all their instruments, and will run down completely sometime in 2026, as expected, when operations will finally cease.

The spacecraft however will continue to fly out into interstellar space. In 40,000 years or so Voyager-1 will get within 1.6 light years of the star Gliese 445 in the constellation Camelopardalis, while at the same time Voyager 2 will pass 1.7 light-years from the star Ross 248 in the constellation Andromeda.

Starliner’s return delayed again

NASA today announced that the return of Starliner from ISS, carrying two astronauts, has been delayed again, from June 18th to June 22nd.

It appears engineers want to perform more tests of the the spacecraft’s attitude thrusters before undocking. The failure of some thrusters during docking on June 6th has raised some concerns.

NASA and Boeing teams also prepared plans for Starliner to fire seven of its eight aft-facing thrusters while docked to the station to evaluate thruster performance for the remainder of the mission. Known as a “hot fire test,” the process will see two bursts of the thrusters, totaling about a second, as part of a pathfinder process to evaluate how the spacecraft will perform during future operational missions after being docked to the space station for six months. [emphasis mine]

The highlighted words are kind of a lie. While there is no doubt this test will tell engineers a lot about future operations, such a test, while attached to ISS, would never have been approved had the thrusters all worked as planned during docking. The real reason for this static fire test is to make sure the thrusters will work once undocked.

If they don’t work, there could be a safety issue putting the astronauts in Starliner for return to Earth.

NASA plans a press briefing on June 18th at noon (Eastern) to outline in better detail the situation.

Study: Dust removal at Jezero 9x greater than InSight landing area

Figure 2 from the paper
Figure 2 from the paper. Click for original.

Using data from the Mars rover Perseverance, scientists have concluded that dust removal rate in Jezero crater is almost ten times greater than where InSight landed in western Elysium Planitia.

The graph, figure 2 from their paper, illustrates that differents starkly. From their abstract:

Dust removal is almost 10 times larger than at InSight’s location: projections indicate that surfaces at Jezero will be periodically partially cleaned. The estimations of the effect of the accumulated dust as a function of time are encouraging for solar-powered missions to regions with similar amounts of dust lifting, which might be determined from orbital data on where dust storms originate, dust devils or their tracks are found, or seasonal albedo changes are noted.

In other words, it might be practical to send solar powered rovers to different places on Mars, if first research was done to see if the conditions there would regularly clear dust from those panels.

This research confirms what had been implied by the different experiences of landers/rovers in different places on Mars. InSight landed near the equator in a region south of the giant shield volcano Elysium Mons. It only survived four years, with steadily lower energy levels, because no wind or dust devil ever cleared the accumulating dust on its solar panels. Spirit meanwhile landed about 1,500 miles southwest of InSight, yet its power levels were still healthy after more than five years of operations, when those operations ended because the rover could no longer move. The rover Opportunity meanwhile on the other side of the planet lasted more than fourteen years. Both rovers relied on solar power, like InSight, but their solar panels kept getting cleared of dust by wind and dust devils.

It is unclear if this wind research has been done for Europe’s Franklin rover, presently scheduled to land in Oxia Planum in 2028. Franklin will rely on solar panels, and though its nominal mission on the surface is only supposed to last seven months, it is always assumed it will continue until the rover fails.

A new lawsuit filed against Elon Musk by former SpaceX employees

Elon Musk, a target for destruction by the left
Elon Musk, a target for destruction

The lawfare won’t stop until morale improves! A new lawsuit has been filed against Elon Musk by eight former SpaceX employees, who now accuse him of sexually harassing them by his sometimes pointed tweets on X, calling those tweets “juvenile, grotesque sexual banter.”

The suit also says Musk’s tweets “had the wholly foreseeable and intentional result of encouraging other employees to engage in similar conduct.”

At SpaceX’s Hawthorne offices, the suit claims, company meetings and employees mimicked Musk’s humor. At meetings, the lawsuit alleges, senior engineers called mechanical parts “chodes” and “schlongs.” A camera that was placed on the bottom of a second-stage Falcon rocket was referred to as the “Upskirt Camera,” and a structure used by astronauts to transfer from SpaceX’s Dragon spacecraft to the International Space Station was called the “Fun Tunnel,” a euphemism for anal sex.

Read the whole article. The complaints are quite hilarious. These employees need to get a life. This is all silly stuff, hardly worth even two nanoseconds of concern.

Unfortunately, these anti-Musk employees do have a life, and it is a very sad one, consumed wholly with destroying Musk, not accomplishing anything worthwhile on their own. These eight former employees are the same ones who were fired after they published an internal letter in SpaceX calling for others in the company to denounce Musk for his tweets. Following their firing they also instigated a National Labor Relations Board (NLRB) suit against Musk, which is presently suspended because SpaceX is claiming the NLRB’s very existence is unconstitutional, and no further action on the complaint will occur until the courts decide on that claim.

This new lawsuit is simply another example of new harassment of Musk by these former employees.

Astronauts cancel ISS spacewalk due to “spacesuit discomfort issue”

UPDATE: A later update by NASA provided no new information on why the spacewalk was canceled, but did announce a new date for the EVA, June 24th, while adding “The crew members on the station are healthy, and spacesuits are functioning as expected..”

My guess is that one of the astronauts had a personal but minor health issue, that out of privacy concerns NASA cannot reveal.

Original post:
——————
A spacewalk planned for today was postponed when the two astronauts involved stopped putting on their spacesuits and instead put them aside “due to spacesuit discomfort issue.”

That is all we know at this point. Was the issue a technical problem with the suits? Or was it something related to the astronauts themselves, such as one experienced stomach problems for instance?

No more details are as yet available. The NASA-designed American spacesuits used on spacewalks on ISS are very complicated and prone to technical problems. If that was the cause it could result in a serious delay before the next spacewalk takes place.

FAA announces schedule for new EIS public meetings on SpaceX’s Starship/Superheavy operations at Cape Canaveral

FAA has now announced the schedule of public meetings in connection with the new environmental impact statement (EIS) it is doing for SpaceX’s proposed Starship/Superheavy operations at Cape Canaveral.

On June 12 and 13, the Federal Aviation Administration (FAA) will host a series of public scoping meetings to inform the public and answer questions about SpaceX’s proposal to launch Starship from Launch Complex 39A (LC-39A). There will also be a virtual meeting on June 17 for those unable to attend in person.

…Among those attending the public hearings will be representative of the Department of the Air Force, the U.S. Space Force, the U.S. Coast Guard, U.S. Fish and Wildlife Service, the Merritt Island National Wildlife Refuge, Canaveral National Seashore and SpaceX.

FAA officials claim this new EIS is required, after doing one only five years ago, because of major changes in SpaceX’s design of Superheavy. For example, it originally planned to land the rocket on a drone ship. Now it wants to catch it with the arms on the launch tower.

The FAA’s argument for this new EIS might sound plausible at first glance, but these regulations were never intended to require new environmental statements every time a project underwent changes. The goal was to make sure the environment would not be impacted by the work, and the first 2019 EIS achieved that. None of the changes SpaceX is proposing change significantly its impact on the local environment.

Moreover, the FAA has three-quarters of a century of empirical data at Cape Canaveral proving that spaceports help the local environment, not hurt it. We know without doubt that none of SpaceX’s launch plans will do harm. The FAA should get out of the way.

Instead, it is sticking its nose into everything. This new EIS is merely mission creep, government bureaucrats both covering their backsides while creating new work that increases their power and justifies bigger budgets for their existence.

Review of 4th Superheavy/Starship flight; FAA clears SpaceX for next flight

Link here. The article provides a detailed step-by-step review of everything that happened on the fourth Superheavy/Starship orbital test flight on June 6, 2024, as well as describing the changes being applied to Starship and Superheavy due to that flight.

However, the article also included this announcement from the FAA, stating that it will not do its own mishap investigation on that flight.

The FAA assessed the operations of the SpaceX Starship Flight 4 mission. All flight events for both Starship and Super Heavy appear to have occurred within the scope of planned and authorized activities.

While this decision means SpaceX can go ahead with the fifth test launch as soon as it is ready — no longer delayed while it waits for the FAA to retype SpaceX’s investigation and then approve it — it is unclear whether this FAA decision will allow SpaceX to attempt a tower landing of Superheavy, with the tower’s arms catching the rocket.

If the FAA has not yet approved a tower landing, I suspect SpaceX will forgo that attempt on the next launch in order to get it off the ground as soon as possible, even as it pushes the FAA for such an approval for a subsequent launch.
