NASA names revised crew for next manned Dragon mission to ISS

9:34 am

NASA today named the two astronauts who will fly on the next manned Dragon mission to ISS, to be launched on September 24, 2024 for a six month mission, where they will be joined by the two astronauts who launched on Boeing’s Starliner in June but now will return with them when their Freedom capsule returns in February 2025.

NASA astronaut Nick Hague and Roscosmos cosmonaut Aleksandr Gorbunov will launch no earlier than Tuesday, Sept. 24, on the agency’s SpaceX Crew-9 mission to the International Space Station. NASA astronauts Zena Cardman and Stephanie Wilson, previously announced as crewmates, are eligible for reassignment on a future mission. Hague and Gorbunov will fly to the space station as commander and mission specialist, respectively, as part of a two-crew member flight aboard a SpaceX Dragon.

The updated crew complement follows NASA’s decision to return the agency’s Boeing Crew Flight Test uncrewed and launch Crew-9 with two unoccupied seats. NASA astronauts Butch Wilmore and Suni Williams, who launched aboard the Starliner spacecraft in June, will fly home with Hague and Gorbunov in February 2025.

With Starliner now scheduled to return on September 6th and Freedom not arriving until around September 24th, there will be an eighteen day period when Wilmore and Williams will have a limited and more risky lifeboat option on ISS. If an incident should occur that requires station evacuation there is room to squeeze them inside SpaceX’s Endeavour Dragon capsule presently docked there, but they will return without flight suits. Their Dragon flight suits will not arrive until September 24th, on the next Dragon. The suits they used on Starliner will not work on Dragon.

First New Glenn launch, set for October 13, 2024, only has an 8-day launch window

9:16 am

According to an article from Aviation Week today, in order for Blue Origin’s New Glenn rocket to get its payload of two Mars orbiters on their way to Mars it must launch within a very short window lasting only eight days, beginning on the present launch date of October 13, 2024.

The Oct. 13-21 launch window is an ambitious goal. The aft and mid modules of New Glenn’s reusable first stage were recently attached, clearing the path for installation of the vehicle’s seven methane-fueled BE-4 engines, CEO Dave Limp noted in an Aug. 23 update on the X social media site.

A static hot-fire at New Glenn’s Florida launch complex is planned prior to launch. The company did not release the status of the New Glenn upper stage, which is to be powered by a pair of BE-3U engines fueled by liquid oxygen and liquid hydrogen. A hot-fire of the second stage is also pending.

This launch will be the first ever for New Glenn. To get ready for that tight launch window it appears a great deal of work must be done in the next six weeks, some of which Blue Origin engineers will be doing for the very first time.

If there are any issues and that launch window is missed, the two NASA Escapade orbiters, built by Rocket Lab, will face a two-year delay until the next window to get to Mars re-opens. At that point New Glenn will likely do this launch with a dummy payload, since it needs to get off the ground in order to fulfill other launch contracts, including a 27-launch contract with Amazon for its Kuiper satellite constellation.

NASA solar sail successfully deploys

9:03 am

After experiencing a technical issue that initially delayed deployment, NASA engineers have now successfully deployed the boom of the 860-square-foot solar sail that had been launched in a cubesat only about four feet in size.

NASA’s Advanced Composite Solar Sail System is now fully deployed in space after a successful test of its sail-hoisting boom system. Mission operators confirmed success at 1:33 p.m. EDT (10:33 a.m. PDT) on Thursday, Aug. 29, after receiving data from the spacecraft. Centrally located aboard the spacecraft are four cameras which captured a panoramic view of the reflective sail and supporting composite booms. High-resolution imagery from these cameras will be available on Wednesday, Sept. 4.

The next step will be to test the sail’s ability to maneuver in space, including raising and lowering its orbit using the pressure of sunlight, just like sailboats use the wind.

NASA awards Intuitive Machines a new lunar lander contract

8:55 am

NASA yesterday announced that it has awarded Intuitive Machines a new lunar lander contract for $116.9 million to carry six NASA/ESA payloads to the surface of the Moon.

The announcement stated that the landing will be in the south pole region of the Moon, but did not reveal the specific location. Of the six science packages, the most important is a European Space Agency-led drill that will obtain samples from as much as three feet down and then analyze them.

The contract calls for a 2027 landing, and will be the fourth targeting the south pole region, following Intuitive Machines first attempted landing there early this year that landed but then tipped over, preventing its science instruments from functioning as planned.

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.

Starliner to return unmanned on September 6

8:44 am

NASA today announced that Starliner will undock from ISS on September 6, 2024 at about 6:00 PM (Eastern) and will then land six hours later at White Sands in New Mexico.

The announcement touts Starliner’s ability to fly autonomously, but based on what we know this is really not something to brag about. All Dragons do this routinely whether they are manned or not. Starliner required an upload of software to reconfirgure it for this, since it had originally been configured for a manned return and apparently that original software was not designed for an unmanned return.

In other words, the spacecraft as presently designed doesn’t have the ability to switch from autonomous to manned in a simple manner.

August 29, 2024 Quick space link

3:17 pm

BtB’s stringer Jay had no quick link stories today, but I thought for completion’s sake I should include this one from yesterday:

  • Blue Origin’s New Shepard yesterday completed its 8th manned suborbital flight

    • Not much else to say. These suborbital flights are nice, but they no longer represent the future, only the past. The future will be illustrated by Polaris Dawn, SpaceX’s next manned commercial orbital flight, scheduled to take off sometime in the next week or so, depending on weather and the FAA’s intransigence.

Fight! Fight! Fight! Jason Moorehead, who was fired for being in Washington on January 6, 2021 to attend a Trump rally at the Washington Monument (never getting within a mile of the Capitol and thus never participating in any way with any violent events there), has now won a wrongful termination suit from the Pennsylvania Allentown School District as well as two school board members.

On Aug. 16, a jury awarded Moorehead $131,500, most of which will come from the district. Two school board members, Lisa Conover and Nancy Wilt, are liable for $6,000 and $500 respectively. Moorehead had not specified a desired dollar amount for “loss of earnings, loss of career, reputational damage, mental and emotional pain and suffering,” and punitive damages.

Moorehead’s lawyer AJ Fleuhr said in statement that he and his client were happy “a federal jury recognized that the Allentown School District violated Jason Moorehead’s First Amendment rights to free speech, assembly, and political affiliation,” and that the named board members had “maliciously and wantonly attacked him.”

Changing Martian slope streaks

12:27 pm

Changing slope streaks on Mars
Click here, here, and here for original images.

Overview map

Time for some cool images from Mars taken over a dozen years! The three pictures above were taken, from left to right, in 2012, 2020, and 2024 and show the same exact Martian terrain. The first two pictures were photographed by the lower resolution context camera on Mars Reconnaissance Orbiter (MRO). The rightmost picture was taken on May 20, 2024 by MRO’s high resolution camera.

The white dot on the overview map to the right marks the location, in the middle of the vast lava flood plains found between Mars’ giant volcanos and north of the Medusae Fossae Formation, the largest volcanic ash deposit on Mars. The 1,200-foot-high mesa pictured above, its peak indicated by the red dot, is part of a group of such mesas that either represent the peaks of a mountain range now mostly buried by lava, or volcanic vents pushed up when those eruptions were occurring more than a billion years ago.

The focus of these pictures however is not volcanism, but the numerous slope streaks seen on the mesa slopes. Note how the 2012 earliest streaks are still visible in 2024, but have faded. Note also how there appears to have been no new streaks since 2020.

Slope streaks are a geological feature unique to Mars that at the moment remain unexplained. At first glance they appear to be a landslide of some kind, but years of orbital study has shown they do not change the topography at all, they never have debris piles at their base, and the streaks even sometimes actually flow up and over small rises in the slopes. They occur randomly throughout the year, and as seen above, over time fade.

Recent research has suggested their formation is related to dust avalanches triggered by dust storms, conclusions that are strengthened by the fact that slope streaks are generally found on dusty slopes, which in this case makes sense as the location is in the dry Martian tropics. That these dust avalanches do not change the topography at all, merely staining it, while sometimes actually flowing up and over rises, illustrates how Mars’ one-third gravity and thin, cold atmosphere makes things happen that are impossible on Earth.

Has the FAA grounded SpaceX?

9:59 am

The FAA statement yesterday seemed quite clear — that the agency was grounding all SpaceX launches until the investigation into the failed landing of a Falcon 9 first stage was completed. That clarity was further accepted by numerous news organizations today, all of which clearly described in their reporting the FAA’s action as a grounding of further SpaceX launches for an unspecified amount of time, from days to weeks. (See here, here, and here for just a few examples.)

Nonetheless, there are strong indications that the FAA’s grounding will be very short. For example, though no dates are presently firm, SpaceX continues to list at least two Starlink launches as well as the Polaris Dawn private manned mission as targeting launches over the next few days, with one Starlink launch still aiming for a 10:18 pm (Pacific) launch tonight from Vandenberg. That liftoff might be tentative, but that SpaceX is still pushing for that launch date suggests it is trying to pressure the FAA to back off.

And SpaceX has good reason to expect that pressure to work. The FAA has already admitted there were no public safety issues from the first stage failure. In the past it has allowed launches to proceed under that condition, even if the investigation was on-going. SpaceX is almost certainly making this point known to the FAA, if its managers don’t know it already. We will find out I think by the end of today.

Even if the FAA backs down, that it even attempted any grounding in this situation was an egregious abuse of its regulatory power. There was no rational reason for it to even hint at doing so, even based on its own regulations as well as its statutory authority. If the goal was to do its job and not to harass SpaceX and Elon Musk, it would have immediately announced that no grounding was required because no issues of public safety were involved in the failure. Instead, it pushed its power, forcing SpaceX to push back.

Lockheed Martin testing its own inflatable module design

9:40 am

Lockheed Martin recently successfully completed a test of its own inflatable module design, conceived in this case not as a full-scale module but as an airlock for ingress and egress from a space station.

In the Aug. 14 test, the inflatable airlock design was put through multiple, gas-in/gas-out cycles — essentially inflations and deflations with enough nitrogen gas to pressurize the airlock to the point it becomes as rigid as steel — to assess the extent to which its Vectran material strains over time, a process called creep. Knowing how creep affects a Vectran structure will allow Lockheed Martin to properly assess its operational life potential. Test engineers here have also put subscale softgoods habitat designs to the test, purposely bursting them to spotlight their robust nature and determine their pressure thresholds.

With the addition of Lockheed Martin, there are now at least four companies building inflatable modules for sale to space station companies. Sierra Space has the most developed module design, but a company in India recently announced it will build and sell its own. In addition, an American startup dubbed Max Space is building its own test module and hopes to launch next year.

NASA leans toward launching Europa Clipper as scheduled, despite transistor issue

9:26 am

Though the final decision will be made in early September, NASA revealed today in a short post that management is leaning towards launching the multi-billion Europa Clipper mission as scheduled on October 10, 2024, despite a very recently discovered transistor issue where the transistors were not properly hardened in construction for the harsh radiation environment surrounding Jupiter.

The next major milestone for Clipper is Key Decision Point E on Monday, Sept. 9, in which the agency will decide whether the project is ready to proceed to launch and mission operations. NASA will provide more information at a mission overview and media briefing targeted for that same week.

The Europa Clipper mission team recently conducted extensive testing and analysis of transistors that help control the flow of electricity on the spacecraft. Analysis of the results suggests the transistors can support the baseline mission. [emphasis mine]

The highlighted sentence suggests NASA officials have weighed the option between launching on time with a limited ability to do science once at Jupiter versus delaying the launch years to fix the transistors, and are now favoring the former option. The cost of delay would be high and long, and NASA officials might believe the bad press for that option would be much greater than a mission that only achieves its bare minimum results. For example, to admit publicly that NASA installed transistors that were not space-hardened when that necessity has been known about since the 1960s would be as embarrassing to the agency as it was for Boeing when it discovered it had installed flammable tape in its Starliner capsule. NASA management might be leaning to letting a flawed multi-billion dollar project launch, knowing its capabilities are quite limited, in order to avoid that embarrassment.

Chinese pseudo-company launches six satellites from off-shore barge

9:12 am

The Chinese pseudo-company Galactic Energy today completed a launch of six satellites, its Ceres-1 rocket lifting off from a barge off the coast of northeast China.

China’s state-run press once again illustrated how fake these pseudo companies are, in that it made no mention of the company in its official report, stating simply that the launch was completed by “China.” The companies might raise investment capital funds and sign contracts and make profits, but in the end they only do what they are told to do by the Chinese communists, and at any point those communists can confiscate the company for the government’s own purposes.

The leaders in the 2024 launch race:

84 SpaceX
36 China
10 Rocket Lab
9 Russia

American private enterprise still leads the rest of the world combined in successful launches 99 to 54, while SpaceX by itself leads the entire world, including American companies 84 to 69.

  • Blue Origin touts the assembly of New Glenn’s first flight first stage

    • The tweet does not say when this was accomplished, but considering the scheduled launch date is only a little more than six weeks away, it seems they are cutting things close indeed. It is clear they are getting close to that first launch, but it is also unclear they can meet the launch window required for their payload, two Mars orbiters.

FAA grounds SpaceX because of first stage landing failure early today

1:36 pm


“Great business you got there! Really be
a shame if something happened to it!”

They’re coming for you next: Once again the FAA has expanded its harassment of SpaceX by now grounding the company from any further launches while it “investigates” the failed landing of a Falcon 9 first stage last night. The FAA statement is as follows:

“The FAA is aware an anomaly occurred during the SpaceX Starlink Group 8-6 mission that launched from Cape Canaveral Space Force Station in Florida on August 28,” the FAA said Wednesday in a statement. “The incident involved the failure of the Falcon 9 booster rocket while landing on a droneship at sea. No public injuries or public property damage have been reported. The FAA is requiring an investigation.”

The FAA’s actions against SpaceX since Biden became president have consistently been unprecedented and biased against the company. » Read more

Today’s blacklisted American: Woman arrested in Arizona for publicly criticizing a public employee

12:55 pm

They’re coming for you next: While making a public comment criticizing the town’s attorney at the local city council meeting for Surprise in Arizona, Rebekah Massie was ordered to either shut up or be arrested by the town’s mayor, Skip Hall, because the council does not allow citizens to make such criticisms during the public comment period.

When she had the audacity to note quite correctly that she was entirely within her first amendment rights to say whatever she wanted, Hall then had her arrested.

I have embedded the video of this event below. It is egregious beyond words.

Evidence of Martian near-surface ice in an unusual location

Evidence of Martian near-surface ice in an unusual location
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on May 27, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). Labeled merely as a terrain sample, it was likely taken not as part of any specific research request, but to fill a gap in the camera’s picture-taking schedule so as to maintain its proper temperature.

The picture however shows features that help confirm earlier research into the near-surface ice believed to permeate Mars’ middle latitudes. The knobby flat terrain both inside and outside of the crater resembles what scientists have labeled “brain terrain”, an as-yet unexplained geological feature unique to Mars and usually associated with near-surface ice and the glacial features found above 30 degrees latitude.

This 1.4-mile-wide unnamed crater is located at 40 degrees north latitude, so expecting near-surface ice or glacial features here is not unreasonable. The location however is different for other reasons, that make this data more intriguing.

Musk: Starlink will be made available to all cell phones in emergencies

9:34 am

Elon Musk has announced that SpaceX will make its Starlink internet constellation available to anyone with a cell phone should they need it during an emergency in remote areas.

The SpaceX CEO made the comments in an X post as the company, in partnership with T-Mobile, currently seeks approval from the Federal Communications Commission to operate its direct-to-cellular Starlink technology commercially. SpaceX says the satellite-based service would provide supplemental cell coverage to Americans from space that would close mobile “dead zones.” Cellular service providers AT&T and Verizon have raised concerns about the technology, including that it would disrupt their own mobile networks.

In a letter to the FCC on Friday, SpaceX said the service would connect first responders in a variety of environments and would be able to send wireless emergency alerts to everyone — not just T-Mobile customers — in places where there is no earth-based cellular coverage.

While this offer is morally correct, it is also good politics, as it acts as icing on the cake to encourage the FCC to approve that T-Moble license request. At the moment the technical details for making the proposal happen remain murky, but SpaceX’s willingness to offer this emergency service at no charge, something its competitors have apparently not, cannot hurt it in its negotiations with the FCC.

Boom completes second flight test of one-third-scale prototype supersonic jet

9:28 am

The airplane startup Boom Supersonic on August 26, 2024 successfully completed the second test flight of its one-third-scale prototype XB-1 supersonic jet, taking off from the Mojave Air & Space Port in California.

The flight was manned by the company’s chief test pilot Tristan Brandenburg, and had as its primary engineering goal to test the retraction and deployment of the jet’s landing gear. During the fifteen minute flight the plane climbed to 10,400 feet and a maximum speed of 277 miles per hour.

The test checklist included retracting and extending the undercarriage for the first time, checking the plane’s handling, and the activation of a new digital stability augmentation system for roll damping to help maintain control in stall conditions. In addition, the right wing of the XB-1 was fitted with tufting to monitor the direction and strength of airflow over the wing.

The company plans a 10-flight test program with this prototype, eventually leading to flights exceeding the speed of sound. Boom also claims that its design will reduce the sound of the sonic boom, thus allowing its commercial supersonic jet to fly over land and increasing its commercial value. At the moment it has orders to sell as many as 96 of its full-scale plane to various airlines, including United and Japan.

SpaceX launches 21 Starlink satellites but loses first stage at landing

8:44 am

SpaceX last night successfully placed 21 Starlink satellites into orbit, its Falcon 9 rocket lifting off from Cape Canaveral in the early morning hours.

The first stage however fell over on its drone ship in the Atlantic after landing. This was its 23rd flight, which would have been a record reuse of a Falcon 9 booster had it landed successfully. Because of this failure, SpaceX rescheduled another Starlink launch, delaying it one day until August 30, 2024, as engineers assessed the stage data to determine the cause of the problem. From the video is appears that one leg on the far side, out of sight, either failed to deploy or collapsed after landing.

To be clear, SpaceX anticipates only a one day delay in all its launches because of this issue.

The leaders in the 2024 launch race:

84 SpaceX
35 China
10 Rocket Lab
9 Russia

American private enterprise now leads the rest of the world combined in successful launches 99 to 53, while SpaceX by itself leads the entire world, including American companies 84 to 68.

Manned Polaris Dawn launch delayed due to weather

9:13 pm

SpaceX tonight scrubbed the launch of Jared Isaacman’s manned Polaris Dawn orbital mission due to poor weather predicted in the splashdown zones off the coast of Florida when the mission would have ended.

The flight has tentatively set now for August 30, 2024, but that remains a very preliminary date.

SpaceX however is not sitting on its hands while it waits for good weather for this manned mission. Tonight it has two Starlink launches scheduled a little more than an hour apart, one from Cape Canaveral in Florida followed by the second from Vandenberg in California. If the first launch is successful its Falcon 9 first stage will set a new record, flying for its 23rd time.

Judge: Vanderbilt student protester who violently took over a building can be prosecuted

1:40 pm

Leftist protesters break into Vanderbilt building
Anti-Israel protesters assault a security guard (grey jacket)
at Vanderbuilt. Click for full video.

The lawless left: A judge ruled this week that Vanderbilt student protester Jack Petocz, who was one of three who violently attacked and injured a security guard in the process of taking over a building on March 25, 2024, was not exercising his first amendment rights and can be prosecuted for assault and face an almost yearlong prison sentence.

Judge Lynda Jones ruled during a preliminary hearing on Thursday that there was probable cause, and told Petocz he’s facing a possible jail sentence of up to 11 months and 29 days for the assault charge. Jones said Petocz may face more time if state prosecutors charge him with aggravated criminal trespass, a Class E felony.

It appears that Petocz was arguing that he was merely exercising his first amendment rights in breaking into the building and occupying it.

NASA IG: NASA’s effort to build new SLS mobile launcher is an epic disaster

12:20 pm

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

According to a new report [pdf] from NASA’s inspector general, both NASA and its contractor Bechtel have allowed the cost and schedule for the new larger SLS mobile launcher (ML-2) (on the right in the graphic) to go completely out of control, with the first launch on that platform to be delayed again until 2029.

NASA projects the ML-2 will cost over three times more than planned. In 2019, NASA estimated the entire ML-2 project from design through construction would cost under $500 million with construction completed and the ML-2 delivered to NASA by March 2023. In December 2023, NASA estimated the ML-2 project would cost $1.5 billion, including $1.3 billion for the Bechtel contract and $168 million for other project costs, with delivery of the launcher to NASA in November 2026. In June 2024, NASA established the Agency Baseline Commitment (ABC)—the cost and schedule baseline committed to Congress against which a project is measured—for a ML-2 project cost of $1.8 billion and a delivery date of September 2027. Even with the establishment of the ABC, NASA intends to keep Bechtel accountable to the cost and schedule agreed to in December 2023.

Despite the Agency’s increased cost projections, our analysis indicates costs could be even higher due in part to the significant amount of construction work that remains. Specifically, our projections indicate the total cost could reach $2.7 billion by the time Bechtel delivers the ML-2 to NASA. With the time NASA requires after delivery to prepare the launcher, we project the ML-2 will not be ready to support a launch until spring 2029, surpassing the planned September2028 Artemis IV launch date.

This quote actually makes things sounder better than they are. Bechtel’s original contract was for $383 million, which means the IG’s present final estimate of $2.7 billion is more than seven times higher. The contract was awarded in 2019 and was supposed to be completed by 2023, in four years. Instead, at best it will take Bechtel a decade to complete the job.

The IG notes that this contact was cost-plus, and considers this the main cause of these cost overruns. It also notes that NASA has had the option to convert the contract to fixed-price, but has chosen not to do so.

Possibly the most damning aspect of the IG report is its conclusion, which essentially admits that nothing can be done to fix this problem.

Webb finds six exoplanets, all flying in interstellar space without a star

11:11 am

Astronomers using the Webb Space Telescope have discovered six different planets ranging in mass 5 to 10 times that of Jupiter, all unattached to any star or solar system.

The most intriguing of the starless objects is also the lightest, having an estimated mass of five Jupiters (about 1,600 Earths). The presence of a dusty disk means the object almost certainly formed like a star, as space dust generally spins around a central object in the early stages of star formation, said Langeveld, a postdoctoral researcher in Jayawardhana’s group.

All of these starless planets likely formed like this one, coalescing like a star does but unlike a star never having enough mass to ignite.

The astronomers are next going to attempt to detect the atmosphere’s of these rogue exoplanets, though it is not clear exactly how they will do this unless one of the exoplanets just happened to transit across a more distant star, something that simply does not happen very often.

D-Orbit newest orbital tug deploys four smallsats

10:24 am

The Italian orbital tug company D-Orbit has now successfully deployed four smallsats from its newest tug, having been launched on August 16, 2024 on a SpaceX Falcon 9 rocket.

The tug still has one more satellite to deploy, after which it will remain in orbit as it also carries four additional customer “hosted” payloads that are using the tug itself as their service module.

This is D-Orbit’s second demo mission, the first flying in 2023. It also appears be completely successful, which puts this company in an excellent position to garner future contracts from many small satellite companies. It is also a partner in a $256 million Italian project to test in-orbit robotic satellite repair.
