SpaceX successfully launches its Endeavour capsule carrying four astronauts

11:59 pm

Capitalism in space: SpaceX tonight used its Falcon 9 rocket to successfully launch its Endeavour capsule from Cape Canaveral, carrying four astronauts to ISS.

This was Endeavour’s fourth flight. It will dock with ISS in about 24 hours. The four-person crew included two Americans, one Russian (the second to fly on a Dragon capsule), and the first citizen of the United Arab Emirates to fly on an American spacecraft. He will stay on the station for six months.

The Falcon 9 first stage was making its first flight, and successfully landed on a drone ship in the Atlantic. This was only the fourth new first stage used by SpaceX since January 2022 (out of 75 launches), and the second launched this year.

The 2023 launch race:

14 SpaceX
7 China
3 Russia
1 Rocket Lab
1 Japan
1 India

American private enterprise now leads China 15 to 7 in the national rankings, and the entire world combined 15 to 12. SpaceX alone leads the entire world combined, including all other American companies, 14 to 13.

Genesis cover

On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.

 

The print edition can be purchased at Amazon or any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.


The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
 

"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

Cool image time! The picture to the right, cropped and sharpened to post here, was taken on January 2, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). Taken to fill a gap in the camera’s planned image schedule in order to maintain its temperature, the location was in this sense picked not for any particular scientific research project, but because the camera team decided they might find something interesting at this spot.

What they found is a vast flat plain of polygons, a feature found frequently on the surface of Mars and thought to be formed from processes similar to the drying that creates similar polygon cracks in dried mud here on Earth. In this case, the cracks are almost certainly in ice. As Colin Dundas of the U.S. Geological Survey’s Astrogeology Science Center in Arizona explained to me previously,

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 the Mars Society.

 

All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount. All editions can also be purchased direct from the ebook publisher, ebookit, in which case you don't support the big tech companies and the author gets a bigger cut much sooner.

 

Autographed printed copies are also available at discount directly from the author (hardback $29.95; paperback $14.95; Shipping cost for either: $6.00). Just send an email to zimmerman @ nasw dot org.

ULA about to be sold?

1:12 pm

According to anonymous sources cited by Eric Berger at Ars Technica today, the rocket company ULA may be sold by the end of this year.

The potential sale has not been disclosed publicly, but three sources confirmed to Ars that potential buyers have been contacted about the opportunity. These sources said a deal is expected to be closed before the end of this year and that investment firm Morgan Stanley and consulting firm Bain & Company are managing the transaction.

Berger correctly lists either Lockheed Martin or Boeing as the most likely candidates to purchase the company, simply by buying out their partner in the consortium. Both companies have strong reasons to obtain this company after the Vulcan rocket is flying. Boeing’s future building SLS is questionable, especially once Starship/Superheavy becomes operational. Lockheed Martin meanwhile has been very carefully moving into the new industry, investing heavily in the rocket startups ABL and Rocket Lab. It might want to own outright ULA, so it can better manage it.

Berger also speculates that Amazon or Blue Origin might be bidders as well. Somehow I doubt any company associated with Jeff Bezos will buy ULA, since he already has his own plaything in Blue Origin. Stranger things however have happened.

Either way, once Vulcan flies successfully it will then be a perfect time to put it up for sale, and others to buy it. The uncertainty will be reduced, and ULA will no longer be saddled with two rocket families, Delta and Atlas-5, both of which are expensive and non-competitive. Instead, it will have solid launch contracts with Amazon and the military, using Vulcan.

Such a sale will obviously also force major changes at ULA, possibly for the better. At such times the new management often uses the change as an opportunity to clean out deadwood as well as force major shifts in thinking.

Today’s blacklisted Americans: Pro-lifers banned from the Washington Monument because it is a “First Amendment-free zone”

12:41 pm

banned by the Biden administration
Banned apparently by the Biden administration

They’re coming for you next: As part of the annual pro-life March for Life demonstration in DC on January 20, 2023, volunteers running a food table were forced to move away from the Washington Monument because, as one park ranger told them, they were in a “First Amendment-free zone.”

The women were setting up a table to provide some fellow pro-life supporters with bagels and coffee when a park ranger told them they were in a “First Amendment-free zone” and had to move out of the granite plaza surrounding the famous obelisk. They relocated on the grass, inches next to the plaza, with the approval of the park ranger. Later, a police officer approached the ladies and told them they were allegedly “getting complaints” about their table being on the path. Police told them they had to leave, and the women complied.

These women had set up the same table at the same spot the year before, with no problems.

Though the granite plaza itself is considered a “restricted zone” where “Activities may only occur within these areas on specified dates to maintain the contemplative and respectful environment of the memorial,” these women were only running a craft service table, an activity that the park service only the year before did not consider a violation of this rule.

Furthermore, we know this was not the reason the ranger and police officer moved to remove them. By his own words, the ranger called this area a “First Amendment-free zone,” thus telling them that they were not allowed to express their opinions there and had to leave, even though the park website itself specifically contradicts this ranger, proudly stating that.

Intelsat develops airplane WiFi antenna that can access both Intelsat and OneWeb satellites

9:48 am

Intelsat has now completed flight tests of a new airplane WiFi antenna designed to access both Intelsat and OneWeb satellites during flight.

By using the Intelsat and OneWeb satellite networks together, Intelsat can offer the benefits of LEO’s low latency along with the redundancy GEO provides to address network hotspots that LEO networks on their own cannot address. Whether aircraft are flying polar regions or over the most populated cities in the world, the ESA antenna will offer seamless coverage from takeoff to touchdown.

At just 90 pounds and with no moving parts, the new antenna stands just 3.5 inches tall on the top of the aircraft. The terminal’s low profile has the lowest drag of any product Intelsat has ever offered.

With this antenna, Intelsat keeps itself in the game. Airlines can provide more complete coverage by using it and signing deals with both OneWeb and Intelsat to provide WiFi to passengers.

UK bureaucracy provisionally clears Viasat-Inmarsat merger

9:40 am

We’re here to help you! The United Kingdom’s Competition and Markets Authority (CMA) has now provisionally approved the merger deal between the two communications satellite companies Viasat and Inmarsat by admitting the obvious, that the deal will do nothing to reduce competition in the presently thriving communications satellite industry.

Over the past 4 months, an independent CMA panel has gathered and scrutinised a wide range of evidence in order to better understand the sector, as well as the potential impact of the deal. This included internal documents from Viasat and Inmarsat, as well as the companies’ competitors (including their plans for future expansion); evidence from airlines; the CMA’s own analysis of sector conditions – and how these could change.

…The CMA’s investigation into the Viasat/Inmarsat deal has provisionally found that, while the companies compete closely in the aviation sector – specifically in the supply of satellite connections for onboard wifi – the deal does not substantially reduce competition for services provided on flights used by UK customers.

Duh. In other words, these bureaucrats spent four months determining what is self-evident to every person who pays any attention to the business of space. Furthermore, both companies are badly threatened by the new players in this industry, like OneWeb and Starlink. This dithering by bureaucrats threatens their survival, as these older companies want to merge to give them the resources to better compete. Being forced to sit and wait only increases the chances that both will go bankrupt, thus reducing competition, the very thing this government agency is supposed to encourage and protect.

Not that the CMA has come to any real decision yet. As its press release notes so nobly, “Today’s findings are provisional, and the CMA will now consult on its findings and listen to any further views before reaching a final decision.”

A Russian Mars airplane?

9:26 am

According to Russia’s state run press, a team of engineers at the Moscow Aviation Institute (MAI), working in partnership with engineers from India, are developing a fixed-wing robotic airplane for use on Mars.

The work on the Marsoplane began in April 2022 after the funding request was approved by the Russian Science Fund. Karpovich believes that the team of scientists will be able to successfully test the technology demonstrator by the end of next year. “By the end of 2024, the Russian side will have to publish ten articles, build and successfully test the technology demonstrator,” she said. [emphasis mine]

It would be nice if this project succeeded but do not get your hopes up. Note the emphasis on the number of papers published. This indicates the goal of this project is not actually building this airplane, but to maintain the careers of its engineers here on Earth. In fact, the whole article has this feel, which by the way is consistent with almost all Russian space projects for the past two decades. Lots of talk, some engineering tests, but nothing real ever gets built that actually flies.

Researchers develop liquid nitrogen spray that removes lunar dust

9:18 am

In a significant breakthrough that might solve a problem that has been on on-going threat to future lunar exploration, researchers at Washington State University have developed a liquid nitrogen spray that appears able to remove the Moon dust that sticks to spacesuits and equipment.

The sprayer removed more than 98% of moon dust simulant in a vacuum environment with minimal damage to spacesuits, performing better than any techniques that have been investigated previously.

You can read their paper here.

During the Apollo lunar landings the astronauts found Moon dust to be a serious problem. It is not only abrasive and attaches itself to everything, it caused in some astronauts what they called “lunar hay fever”, suggesting that on longer Moon missions the dust could cause serious health issues.

The process is not yet perfected. For example, it has not yet been tested in lunar gravity. Moreover, techniques for applying this spray practically during actual lunar operations do not yet exist. Nonetheless, this appears to be the first technique found that might work.

No resolution in sight for Blue Origin’s investigation into New Shepard flight abort

9:00 am

According to one Blue Origin official, the company’s investigation into the New Shepard flight abort continues without resolution, nearly six months after the incident occurred shortly after launch on a flight in September 2022.

Speaking at the Next-Generation Suborbital Researchers Conference here Feb. 28, Gary Lai, chief architect for New Shepard at Blue Origin, said the company was continuing to investigate the Sept. 12 uncrewed mission, designated NS-23. On that flight, the crew capsule, which had experiments but no people on board, fired its launch escape motor about a minute after liftoff from the company’s West Texas test site.

The company has provided few updates about the status of the investigation since the incident and has not estimated either when the investigation would be complete or when New Shepard flights would resume. “We are investigating that anomaly now, the cause of it,” he said after a talk about New Shepard at the conference. “We will get to the bottom of it. I can’t talk about specific timelines or plans for when we will resolve that situation other than to say that we fully intend to be back in business as soon as we are ready.”

The pace of this investigation fits the generally slow manner in which Blue Origin appears to do everything. Six months later and it appears as if its engineers are still unclear about the cause of the abort. Nor is the company able to say when it will resume launches. This slow response matches the very leisurely pace the company set to fix its BE-4 orbital rocket engines, a pace so slow it caused a three year delay in the launch of ULA’s Vulcan rocket, and an even longer delay (with no end in sight) for Blue Origin’s own New Glenn rocket.

Considering that it has customers waiting to fly, this slow pace will not recommend it to future or even present customers. It would not surprise me if several — for both the suborbital and orbital spacecraft — quietly jump ship and arrange launch services elsewhere.

Layers upon layers on Mars

3:47 pm

Layers on Mars
Click for original image.

Today’s cool image once again illustrates that the geology of Mars will almost certainly center on a study of layers, as increasingly the orbital and rover images are telling us that the red planet is covered with innumerable layers, one after another, each created by another cycle, some seasonal, some global, and some related to climate and the planet’s fluctuating rotation tilt as well as its orbit around the Sun. And some might also be random volcanic events, unrelated to the cycles.

The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on October 10, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). Labeled by the science team “Layering in western Arabia Terra”, this section only shows a small amount of the layering visible in the full image. From east to west the ground rises in a series of terraces, each representing a different layer of distinct geology.

Today’s blacklisted American: University tells student it will block her speech, even off campus and on her private time

1:56 pm

Elisa Carroll: censored by Villanova
Villanova student Elisa Carroll

They’re coming for you next: Villanova University recently told one of its students, Elisa Carroll, that it has the right to stop her from distributing pro-choice literature or contraceptives, even if she is doing it on a public sidewalk off campus and on her own time.

Carroll, recognizing that as a religious college Villanova would not provide contraceptives for its students, wanted to make them available anyway. She also recognized that she should not do it on campus, in order to respect the university’s stance. Instead, she decided to set up an unaffiliated organization that would offer such things close to but off-campus.

The university decided this was still unacceptable, and moved to forbid it.

Villanova Director of Student Involvement JJ Brown told Carroll the university would prevent her from distributing the contraceptives on a public sidewalk near campus. Brown told her that given the sidewalk’s proximity to campus and because Carroll is a Villanova student, the university could prevent her from promoting any contraceptive advocacy organizations there, including by handing out contraceptives.

In response, Carroll asked for help from the Foundation for Individual Rights and Expression (FIRE), which immediately fired off a letter to Villanova, telling it in no uncertain terms the illegality as well as the immorality of its threat.

The panorama above, cropped, enhanced, and annotated to post here, was taken by left navigation camera on the Mars rover Perseverance on February 27, 2023, looking ahead at its future path on the delta that flowed into Jezero Crater sometime into the past. The arrow points at Ingenuity, now sitting ahead of the rover after completing its 46th flight sometime this weekend.

On the overview map to the right, Perservance’s present location is indicated by the blue dot. The green dot marks Ingenuity’s position, and the yellow lines indicate the approximate area viewed by the panorama above. The red dotted line indicates Perseverance planned future route, though it is likely the science team will make many side trips along the way. The bigger dots are points of special interest, where the scientists hope to drill for core samples.

The ridge on the right is the rim of Belva Crater. The higher mountain behind it is likely the rim of Jezero Crater itself, about four miles away. The helicopter sits about 250 feet away.

Unlike the rocky terrain where Curiosity is presently traveling in the foothills of Mount Sharp in Gale Crater, the terrain here in Jezero Crater appears much more benign, almost like a sand desert of dunes. This is not sand, nor are the hills dunes, but wind erosion and dust appear to have smoothed and hidden the geology more than in Gale Crater.

ESA invites private companies to build lunar satellites for communications and navigation

9:47 am

Capitalism in space: The European Space Agency (ESA) has now invited European and Canadian companies to build the lunar communications and navigation satellites that will be needed to serve the many future manned and unmanned missions presently being planned by the U.S. and Europe.

Under its Moonlight programme, ESA is inviting space companies to create these lunar services.

By acting as an anchor customer, ESA is enabling space companies involved in Moonlight to create a telecommunication and navigation service for the agency, while being free to sell lunar services and solutions to other agencies and commercial ventures.

Once Moonlight is in place, companies could create new applications in areas such as education, media and entertainment – as well as inspiring young people to study science, technology, engineering and maths, which creates a highly qualified future workforce.

According to the press release, almost 100 companies have already expressed interest.

It is however unclear how much freedom the companies will have in designing and creating these satellites, based on ESA’s own descriptions of the project. It appears that ESA wants to design them, and is simply looking for private companies to build them. Under this arrangement, ownership will not belong to the companies, even if they are given the freedom to make money selling the capability to others. In fact, past history suggests that in the end, ESA will eventually retract this part of the deal, because of its desire to fully control the satellites it designed.

NASA names solar scientist as its new science head

9:32 am

NASA today announced the appointment of solar scientist Nicola Fox as the chief of the agency’s science division, taking over from solar scientist Thomas Zurbuchen.

Fox’s actual qualifications for the job are stellar.

Born in Hitchin, Herefordshire, England, Fox received a B.S. in physics from The Imperial College of Science, Technology and Medicine in London, an M.S. in Telematics and Satellite Communications from the University of Surrey, and returned to Imperial College London for her Ph.D. in Space and Atmospheric Physics. She worked at NASA’s Goddard Space Flight Center before joining APL in 1998.

At NASA Fox has led its the solar science division, as well as been the project scientist for the Parker Solar Probe, presently orbiting the Sun.

For the Biden administration and our modern culture that unfortunately always seems more focused on race and gender, the only thing that really matters about Fox however is her sex, a fact that the linked article seems obligated to mention in this manner:

Only one other woman, Mary Cleave, an environmental research engineer and former astronaut, has headed [the science division] in the agency’s almost 65-year history.

How evil! Our racist society oppressed women all those years, holding them back!

In fact, it is actually becoming increasing difficult for any white and heterosexual male to get major management jobs anywhere. The race- and gender-baiters always talk about getting rid of the “glass ceiling,” but in their obsession with giving jobs to woman and minorities, they have simply placed it over others.

Ispace provides update on its Hakuto-R1 lunar lander on the way to the Moon

9:09 am

Lunar map showing Hakuto-R1's landing spot
Hakuto-R1’s planned landing site is in Atlas Crater.

The CEO of the Japanese company Ispace yesterday gave a media briefing on the status of its Hakuto-R1 lunar lander, essentially stating that the spacecraft is doing fine and is on target to land on the Moon at the end of April as planned.

Ispace CEO Takeshi Hakamada said during a media briefing Monday that the flight has provided operational data that will inform subsequent missions. “We have acquired tons of data and know-how” on the lander and its subsystems, he said. “They are very viable assets for ispace.”

That includes information on the lander’s structural performance during launch and deployment, as well as the performance of thermal, communication and power subsystems. “It’s almost impossible to assume everything perfectly before the mission,” Hakamada said. “It is inevitable to face off-nominal events.” Some off-nominal events in the mission so far include thermal temperatures hotter than the company anticipated and a brief, unexpected issues with communications after the lander deployed from the Falcon 9. The thermal issues have not affected operations.

This mission, while carrying commercial payloads such as the UAE’s Rashid lunar rover, is mainly aimed at finding out these engineering details in order to make the next two missions in ’24 and ’25 more likely to succeed. The ’24 mission is also planned as a test mission, but it will carry commercial payloads for both Japanese and Taiwanese customers. On the ’25 mission, the main customer is NASA.

The shift away from government schools, at all levels, accelerates

3:51 pm

Parents are rejecting this in droves
Parents are rejecting this mantra in droves

It has been clear for decades that the public schools in most major urban areas — all of which have been run by Democrats — have been failing badly at their primary task of educating children. Two recent stories underlined this failure.

First, in Baltimore a study found that not one student in twenty-three of the city’s schools was proficient in math.

Through an analysis of 150 Baltimore City Schools, 23 of them, including 10 high schools, eight elementary schools, three high schools and two middle schools, no students met math grade-level expectations, according to a report by Project Baltimore. Approximately 2,000 students took the state administered math exams that tested proficiency levels.

…An additional 20 schools in the district had no more than two students proficient in math, Project Baltimore reported. Another three schools in the district, which are for incarcerated students and students with disabilities, had no students that met grade-level expectations.

Essentially, just under one third of all of Baltimore’s public schools failed to teach any of their students math. Period. For any school system to accept this level of failure is beyond disgusting. Everyone who works for Baltimore’s schools should be canned, now.

Then, just days later, another story revealed that fifty-five of Chicago’s public schools were also totally incompetent at teaching math or reading, and should find other work.

Drilling success for Curiosity in the marker layer?

The fifth drill hole in the marker band
Click for original image.

It appears from the most recent image sent back from Curiosity today of its February 25, 2023 attempt to drill into the marker layer on Mount Sharp — the fifth such attempt — the rover finally succeeded in getting deep enough to collect sufficient sample material for analysis.

That image is to the right, cropped, reduced, and sharpened to post here. Note that it is not yet confirmed from the science team that this drill attempt was deep enough. What makes this particular drilling attempt intriguing is how the many thin layers of the marker layer responded to the stress of the drill. The top layer cracked like a plate and separated from the adjacent lower layer during drilling. It apparently was hard enough to retain most of its structure, and rather than crumble the drill stresses caused a large section to break away and lift off.

The panorama above, cropped and reduced to post here, was taken the same day from this location, produced from 37 photos taken by the rover’s right navigation camera. The cropped section above looks forward at what I previously labeled “a Martian hill of pillows.” The overview map below shows the context of this panorama.

Galaxies afloat in space

Galaxies afloat in space
Click for original image.

Cool image time! The picture to the right, cropped and reduced to post here, was taken by the Hubble Space Telescope and released today. It is part of a survey project studying what the press release calls “jellyfish galaxies,” spiral galaxies that have long extended arms.

As jellyfish galaxies move through intergalactic space they are slowly stripped of gas, which trails behind the galaxy in tendrils illuminated by clumps of star formation. These blue tendrils are visible drifting below the core of this galaxy, and give it its jellyfish-like appearance. This particular jellyfish galaxy — known as JO201 — lies in the constellation Cetus, which is named after a sea monster from ancient Greek mythology. This sea-monster-themed constellation adds to the nautical theme of this image.

On the lower left is what the press release calls an elliptical galaxy, probably because it has no obvious arms. It is however shaped more like a spiral galaxy, since ellipticals tend to be spherical. If you look close you will also notice at least five-plus other galaxies in this picture, all smaller either because they are much farther away or are simply much smaller.

New company aims at providing floating ocean-going spaceports for rocket companies

9:29 am

A new startup, The Spaceport Company, is building a floating ocean-going spaceport for smallsat rocket companies, with the company’s long term goal to provide a range of floating spaceports for rockets of all sizes.

The Spaceport Company is planning to demonstrate a sea-based launch platform in May, conducting four sounding rocket launches from a modified ship in the Gulf of Mexico. “That will help us prove out our logistical, operational and regulatory procedures,” said Tom Marotta, founder and chief executive of the company, during a panel at the SpaceCom conference Feb. 23.

Those tests will be a precursor to developing a full-scale sea-based platform, based on a ship design called a liftboat. That ship can sail to a location and lower legs to anchor itself on the seafloor. The boat can then lift itself out of the water and serve [as] a launch platform.

That first orbital platform would provide launch services for smallsat rockets capable of launching up to one ton, and if the company’s suborbital test launches go well and further investment capital arrives, could be operational by 2025.

Astroscale raises $76 million in private investment capital from Mitsubishi, space tourist Maezawa, and others

9:20 am

The Japanese startup Astroscale, which is focused on removing orbital space junk and robotic satellite repair, has raised $76 million in private investment capital, bringing the total it has raised from private sources to $376 million.

Astroscale Holdings Inc. (“Astroscale”), the market leader in satellite servicing and long-term sustainability across all orbits, has closed a Series G round with more than U.S. $76 million in funding from new investors Mitsubishi Electric, Yusaku Maezawa, Mitsubishi UFJ Bank, Mitsubishi Corporation, Development Bank of Japan, and FEL Corporation.

The investors are of interest. Billionaire Maezawa, who has already flown to ISS as a tourist and has purchased a lunar mission on SpaceX’s Starship, contributed $23 million of the $76 million. Mitsubishi in turn has contributed at least $25 million. Both suggest Astroscale is now on very solid financial ground.

It also appears that the big players in Japan see Astroscale’s business plan as viable and expected to be profitable.

Manned Endeavour launch tonight on Falcon 9 scrubbed at T-2:12

12:05 am

UPDATE: New launch date, still tentative pending investigation into the technical issue that forced tonight’s scrub, is now March 2, 2023, at 12:32 am Eastern.

The fourth manned launch of SpaceX’s Endeavour Dragon capsule, carrying four astronauts, was scrubbed tonight at T-2:12 because of an issue with ground ignition system of the rocket. As of posting no additional details had been released, as the launch team was in the process of standing down, unloading the fuel from the rocket in preparation for getting the astronauts out of the capsule safely.

Assuming the issue can be fixed quickly, there is another launch opportunity tomorrow, February 28, at 1:22 am (Eastern). For SpaceX a launch scrub for technical reasons has become remarkably rare. In fact, the only other scrub since 2020 for technical reasons took place in July 2022. During that time the company successfully launched more than 100 times, thus getting off the ground as scheduled about 99% of the time, excluding weather delays.

While the Endeavour capsule will be making its fourth flight, when this launch finally takes place the rocket’s first stage is a new stage and will be making its first flight. This has also become a relatively rare event for SpaceX. In 2022, of the company’s 61 launches, only three used new first stages. So far this year this launch will be the second new stage to fly, out of the thirteen launches so far.

IBEX in safe mode

11:38 am

On February 18, 2023, NASA’s Interstellar Boundary Explorer (IBEX) went into what the engineers have dubbed “contingency mode”, which seems to be a variation of safe mode, due to a computer issue that is preventing the spacecraft from accepting commands.

While fight [sic] computer resets have happened before, this time the team lost the ability to command the spacecraft during the subsequent reset recovery. The team also was unsuccessful in regaining command capability by resetting ground systems hardware and software.

Flight software still is running, and the spacecraft systems appear to be functional. However, while uplink signals are reaching the spacecraft, commands are not processing. If the mission team’s efforts to find and remedy the loss of command capability remain unsuccessful, IBEX will perform an autonomous reset and power cycle on March 4.

IBEX was designed to study the boundary between the interstellar space and the solar system, and do it somehow from Earth orbit.
