SpaceX destroys Starship prototype #7, as planned

September 24, 2020 12:46 pm Robert Zimmerman

Capitalism in space: SpaceX last night successfully pressurized its seventh Starship prototype to failure, as planned.

The culmination of three nights and more than 20 hours of concerted effort, SpaceX was finally able to fill Starship test tank SN7.1 with several hundred tons of liquid nitrogen before dawn on September 23rd. With just an hour left in the day’s test window, SpaceX closed the tank’s vents, allowing its cryogenic contents to boil into gas and expand with no outlet. At 4:57 am CDT, SN7.1 burst, bringing its lengthy test campaign to a decisive end.

I have embedded video of the test below the fold.

With the completion of this test the way is now clear for the 60,000 foot hop of Starship prototype #8, no earlier than October 11th.

Axiom, SpaceX, and NASA finalizing first wholly private manned mission

September 24, 2020 12:38 pm Robert Zimmerman

Capitalism in space: Axiom, SpaceX, and NASA are close to finalizing the deal for the first wholly private manned mission to ISS, tentatively set for October 2021.

One of the topics Axiom is negotiating with NASA involves how much insight the space agency will have into the private astronaut mission. While the Axiom missions will be managed by commercial companies, the AX-1 flight will fly with a reusable Crew Dragon spacecraft that will carry NASA astronauts on other missions. “There’s a certain amount of insight (NASA) would like on our flight, on a commercial flight,” [Axiom official] Suffredini said Friday. “So that is one aspect of that process. We’re using a vehicle that is going to be re-flown, and NASA will certify the re-flights because they want to do re-flights.”

Axiom and SpaceX will also have to confirm a schedule with NASA for the AX-1 mission to dock with the space station. The orbiting research complex has a busy schedule of arriving and departing crew and cargo vehicles, and managers also have slot in spacecraft dockings amid spacewalks, experiments, and other critical operations.

NASA also oversees safety of the space station with the program’s international partners.

The private companies however will in the end be responsible for the flight.

There have been rumors that the passengers on this flight will be Tom Cruise and his film director, though this is not confirmed. Also, these same arrangements will be used for the tentative 2023 private flight of the winner of a proposed reality television show dubbed Space Hero.

Blue Origin scrubs New Shepard flight today

September 24, 2020 12:21 pm Robert Zimmerman

Capitalism in space: Blue Origin today scrubbed the first New Shepard flight in ten months.

From the company:

We’ve detected a potential issue with the power supply to the experiments. Launch is scrubbed for today. New launch target forthcoming.

Ten months since their last flight, and the power supply to the experiments has a problem the day of the launch? Sorry if I sound harsh, but that does not speak well for the company’s quality control systems.

OSIRIS-REx team confirms date for sample grab from Bennu

September 24, 2020 12:16 pm Robert Zimmerman

Click for full image.

The OSIRIS-REx science team has confirmed October 20, 2020 as the date the spacecraft will attempt a sample grab from the asteroid Bennu.

OSIRIS-REx is charged with collecting at least 2 oz. (60 grams) of Bennu’s rocky material to deliver back to Earth – the largest sample return from space since the Apollo program – and the mission developed two methods to verify that this sample collection occurred. On Oct. 22, OSIRIS-REx’s SamCam camera will capture images of the TAGSAM head to see whether it contains Bennu’s surface material. The spacecraft will also perform a spin maneuver on Oct. 24 to determine the mass of collected material. If these measures show successful collection, the decision will be made to place the sample in the Sample Return Capsule (SRC) for return to Earth. If sufficient sample has not been collected from [the primary landing site] Nightingale, the spacecraft has onboard nitrogen charges for two more attempts. A TAG attempt at the back-up Osprey site would be made no earlier than January 2021.

The press release at the link provides a lot of technical and interesting details about the sample-grab-and-go attempt, expected to put the spacecraft in contact with the asteroid’s surface for no more than sixteen seconds.

The maneuver itself is quite risky, as the available smooth landing area, as shown in the image above, is only half the size the equipment was designed for, and surrounded by large boulders.

Corroding glacier in crater rim gully?

September 24, 2020 9:45 am Robert Zimmerman

Click for full image.

Today’s cool image to the right, rotated and cropped to post here, shows a gully flowing down the north facing rim of a 30-mile-wide crater in the southern cratered highlands. It was taken on June 30, 2020 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

To my eye the corroded ridges and pits running down the western side of this gully look like a corroded ice, as if we are looking at a glacier that the light of the Sun, which in the southern hemisphere hits this north-facing slope more directly and for longer periods of time, is causing it to sublimate away with time.

The wider shot below shows the entire rim, flowing downhill from the south to the north.

California to ban all gas-powered vehicles

September 23, 2020 8:55 pm Robert Zimmerman

This is not the Babylon Bee: California Democratic governor Gavin Newsom today announced that as of 2035 the state will outlaw all gas-powered vehicles.

Newsom said that his new executive order would “eliminate” the sales of “internal combustion engines” and move to electric vehicles — a move that he said would create jobs and allow California to “dominate” the market, and address climate change. Those who currently own gas-powered vehicles would still be allowed to operate them and to sell them on the used market.

2035 happens to be the same year that former Vice President Joe Biden has set as a deadline for the U.S. to eliminate fossil fuels from electricity production, five years later than originally proposed by Rep. Alexandria Ocasio-Cortez (D-NY) in her “Green New Deal.” Ocasio-Cortez led the climate change panel on the “Biden-Sanders Unity Task Force” earlier this year.

The ignorance displayed by this policy decision is spectacular. These Democrats obviously believe that the power from electric cars comes from magic. They also seem to believe that new technology can magically be decreed, by government fiat.

What this degree will do is bankrupt California, and make living there a living hell, suitable only for the very very rich or the very very poor (whose survival will be wholly dependent on those very very rich).

Remember this when you go to vote in November. Newsom, Ocasio-Cortez, and Biden are very typical of the modern Democratic Party. Give it power and it will do the same for the entire nation.

Survival rates for COVID-19

September 23, 2020 8:43 pm Robert Zimmerman

The CDC last week posted its new estimate of the survival rates for COVID-19, broken up by age.

This link put those number in clear terms:

0-19 years: 99.997%
20-49 years: 99.98%
50-69 years: 99.5%
70+ years: 94.6%

Those numbers are practically identical to those of the flu. In other words, practically no one dies from it. It makes some people sick for a week or so, and then goes away.

And we have destroyed western civilization over this. It boggles the mind (for those who are still using it).

The worst part is that no one will believe me. Instead, too many will be outraged that anyone would even hint that this virus is not the plague.

Four graphs prove the utter failure of lockdowns and masks

September 23, 2020 5:43 pm Robert Zimmerman

The data is now in. Not only is the coronavirus nothing more than a very bad flu, harmless to the vast majority of the population, the bad policy imposed by almost all governments worldwide has done nothing to alleviate it, and in fact has probably helped kill people, from both the virus and their bad policy.

This conclusion is starkly illustrated in the following four graphs (source), all of which show the history of COVID-19 during the entire 2020 epidemic, now clearly ending. All four graphs are updates of graphs I’ve referenced previously, but now they take us through the epidemic’s present waning, and give us a better context of both the virus’ flu-like nature and the terrible policies imposed by governments in their panic over it.

Daily mortality from COVID-19 in the U.S.

First to the right we have the daily mortality numbers for the entire United States. The steady drop in deaths since epidemic’s second peak on August 12th is very evident. The epidemic appears to be winding down, though very slowly. Furthermore, it had an unusual summer peak that is almost never seen in such respiratory diseases. The reasons for both the slowness of the virus’s decay and its second peak will become clear as we look at the next three graphs, covering the epidemic’s peak in New York, New Jersey, and California.

The first Starlink user test results

September 23, 2020 9:50 am Robert Zimmerman

Capitalism in space: The first Starlink test results by actual users are finally coming out, and they suggest that the constellation will deliver very fast internet speeds indeed.

The article however reveals this tidbit that up until now SpaceX has managed to keep nicely obscured:

While Starlink will provide the kind of speeds and latency that should work for many services and games, Musk said the company simply won’t have the capacity to compete in major metro markets—a caveat often left unmentioned in Starlink coverage. “It’s not good for high-density situations,” Musk said. “We’ll have some small number of customers in LA. But we can’t do a lot of customers in LA because the bandwidth per cell is simply not high enough.”

As a result, Starlink won’t do much for the estimated 83 million Americans stuck under a broadband monopoly (usually Comcast), or the millions more whose only options are a duopoly; usually either the cable company or a sluggish DSL line from the local phone company.

In other words, the service will likely not be made available in dense urban areas, at least not initially.

New Shepard test flight set for tomorrow

September 23, 2020 9:42 am Robert Zimmerman

Capitalism in space: Blue Origin has scheduled a New Shepard test flight set for tomorrow morning at 10 am (Central), the first test flight in ten months.

This will be the seventh flight of this particular New Shepard spacecraft, the thirteenth overall for the program.

In March the company’s CEO had promised three flights by the end of 2020, with the last manned. The press release above howeveronly mentions that tomorrow’s test flight is the first of two, both now emphasizing how they will be flying payloads testing technology for lunar landings. No mention is made of a later manned mission.

It seems increasingly that Blue Origin is abandoning its suborbital space tourism business. If not, they sure don’t seem very enthusiastic about it any longer. Instead, they appear to be hyping New Shepard as a testbed for their effort to develop the manned lunar lander for NASA.

That same March update from the CEO had also said they would be initiating commercial production of their BE-4 rocket engine this year. All we have had so far is delivery of one testbed engine — not flightworthy — to ULA. ULA soon revealed there are problems with the engine.

All in all, Blue Origin is becoming less and less impressive, as time passes. Their suborbital tourism project appears to be abandoned. Their rocket engine has problems. And their New Glenn orbital rocket appears stalled.

All they have right now is their development contract with NASA to build a manned lunar lander, and in that case Blue Origin is only a minor player, even if the company is listed as the lead contractor. Their big partners (Lockheed Martin, Northrop Grumman, and Draper) will build the bulk of the lander, should NASA finally get the project financed by Congress.

The company’s failure to deliver so far is a true shame, as the company has ample finances, backed by Jeff Bezos’ billions.

A patch of chaos in the Martian cratered southern highlands

September 22, 2020 1:12 pm Robert Zimmerman

Click for full image.

Today’s cool image, rotated, cropped, and reduced to post here, takes us to the cratered southern highlands of Mars. Taken by the context wide angle camera on Mars Reconnaissance Orbiter, this image shows us a strange isolated patch of what appears to be chaos terrain, which on Mars generally means an area of random knobs and mesas cut by canyons and channels.

The large bulk of chaos terrain on Mars is found near or in the transition zone between the lowland northern plains and the southern cratered highlands, and is thought to have been created by slow erosion, possibly by glaciers. This erosion process is aided by the gradient downhill from those highlands to the lowlands.

This location however is in the middle of the cratered highlands, and shows no obvious slope in any direction. And though the location is in the mid-southern latitudes, there is no obvious evidence of glaciers among these knobs and mesas. Furthermore, the mesas are not all the same height. Instead, a large portion appear to have been shaved off, as if some giant came in with a putty knife and scrapped away at them.

This can be clearly seen by the close-up below, taken by MRO’s high resolution camera on July 16, 2002 of the area indicated by the white box, which for scale is about 2 1/4 miles square.

NASA lays out Artemis budget and plan to get astronauts to Moon

September 22, 2020 10:10 am Robert Zimmerman

In a obvious lobbying effort to get Congress to fund the Trump administration’s Artemis project to land humans on the Moon by 2024, NASA yesterday released a new updated plan and budget for the program.

More here.

The document [pdf] outlines the specific plans for each of the first three Artemis flights, with the first unmanned, the second manned and designed to fly around the Moon, and the third to land a man and a woman on the Moon. Overall the plan is budgeted at about $28 billion, with $3.2 billion needed immediately to fund construction of the lunar lander. From the second link:

Bridenstine said he remains optimistic Congress will fully fund lander development because of what he described as broad bipartisan support for the Artemis program. He said he’s hopeful an expected continuing resolution that would freeze NASA’s budget at last year’s spending levels will be resolved in an “omnibus” spending bill before Christmas or, if the CR is extended, by early spring. “It is critically important that we get that $3.2 billion,” he said. “And I think that if we can have that done before Christmas, we’re still on track for a 2024 moon landing. … If we go beyond March, and we still don’t have the human landing system funded, it becomes increasingly more difficult.”

And what happens then?

“It’s really simple. If Congress doesn’t fund the moon landing program, then it won’t be achieved (in 2024), I mean it’s really that simple,” Bridenstine said. But he quickly added: “I want to be clear, if they push the funding off, our goal will be to get to the moon at the earliest possible opportunity.”

I remain doubtful the present Congress, with the House controlled by the Democrats, will fund this 2024 lunar landing. Since 2016 the entire political platform of the Democratic Party has been “oppose anything Trump.” They will not fund this project if it means he will get this landing during his second term.

If however Trump loses in November, the lame duck Congress might then go ahead and fund it before December, since the landing in 2024 will then occur during the Biden presidency.

Technically the plan reveals that NASA is trying to accelerate the development of the rendezvous and docking software for Orion. During the second flight, the first manned, the crew will do proximity maneuvers with the upper stage of the rocket. Under previous management NASA had not included this ability, as they had not planned to have Orion do any rendezvouses or dockings. That lack makes it impossible for Orion to fly on any other rocket but SLS. This change means the Trump administration recognizes this is a problem, and wants to fix it, especially because they also recognize that SLS is a poor long term option for future lunar missions.

OneWeb announces new launch schedule, cancels Ariane 6 launch

September 22, 2020 9:47 am Robert Zimmerman

Capitalism in space: OneWeb, as it restructures itself after its purchase by a partnership of an Indian company and the UK government, has announced a new launch schedule for completing its satellite communications constellation by 2022, with the first launch in December.

The key change is that they have cancelled their deal to fly OneWeb satellites on the first launch of Arianespace’s Ariane 6 rocket. From the first link:

Arianespace will conduct 16 Soyuz launches for OneWeb, each carrying 34-36 satellites, to complete OneWeb’s internet megaconstellation by the end of 2022. The revised contract canceled two Soyuz launches, and removed OneWeb as the customer for the inaugural Ariane 6 launch, an Arianespace spokesperson told SpaceNews.

The Ariane 6 cancellation is bad news for Arianespace’s new rocket, which has had trouble garnering customers. I am sure OneWeb was offered a great price to launch some satellites on that inaugural flight, and still OneWeb backed out.

For Russia this announcement is good news, even if they have lost two Soyuz launches. It means the bulk of their Soyuz launches will go forward, pumping money into the Russia’s starving commercial launch industry. This launch contract is essentially the only Russian commercial contract, with SpaceX stealing all of Russia’s former customers, and the bankruptcy had threatened it.

Finally, this announcement shows that OneWeb’s new owners have recognized that they have to get their satellites launched as fast as possible if they are going to compete with SpaceX’s Starlink constellation.

UAE to train astronauts at NASA

September 22, 2020 9:29 am Robert Zimmerman

The United Arab Emirates has signed an agreement with NASA to train its two future astronauts to ISS.

UAE astronauts Hazzaa AlMansoori and Sultan AlNeyadi have already begun their training at Nasa’s Johnson Space Center in Houston starting Monday, Salem AlMarri, head of the UAE Astronaut Programme, at the Mohammed Bin Rashid Space Centre (MBRSC), said during a media briefing. AlMansoori and AlNeyadi had earlier trained at the Yuri Gagarin Cosmonaut Training Center in Star City, Moscow, in September 2018 as part of their preparation for their launch to the ISS.

The two men will be launched to ISS by Russia using its Soyuz rocket and capsule. However, the UAE is smart to get them training in the U.S., as they need to work with U.S. mission control and U.S. systems on ISS. Moreover, I expect the UAE might wish to buy tickets eventually on either Dragon or Starliner, and this training lays the groundwork for that possibility.

Ryugu, like Bennu, appears to have rocks from other asteroids

September 22, 2020 9:21 am Robert Zimmerman

Japanese scientists today announced that 21 rocks identified by Hayabusa-2 on the asteroid Ryugu have a composition that suggests they were formed on another asteroid.

Although Ryugu’s surface is uniformly dark [because it is a C-type asteroid], the scientists behind the new research found numerous boulders scattered across the asteroid that were 1.5 or more times brighter than their surroundings — that is, they reflected at least 50% more light than most of the rest of Ryugu. This contrast made the researchers suspect these boulders may have come from outside the asteroid.

By analyzing the spectrum of light reflected off 21 of these boulders, the scientists deduced they were made of minerals known as anhydrous silicates. Prior studies have suggested that such water-poor, silicon-rich rocks make up silicaceous or S-type asteroids, the most common kind of asteroid found in the inner main asteroid belt. The brightness of these boulders also matches the brightness of S-type asteroids.

This result compliments the result yesterday from scientists studying Bennu with OSIRIS-REx, and was in fact released at the same time. Both asteroids apparently contain material from other asteroids, suggesting that asteroids in their initial formation (as rubble piles) are routinely a mixture of material from many asteroids, thrown out during impacts and then recaptured.

Despite fading epidemic governments vow to maintain lockdowns

September 21, 2020 2:52 pm Robert Zimmerman

Graph of U.S. deaths day to day through September 21, 2020

The lockdowns will never end: Despite the continuing and steady decline in COVID-19 deaths and cases, most state governments are vowing to maintain their lockdowns and mask mandates, some forever or until a vaccine is found.

Numerous high-ranking public authorities throughout the United States have pledged to continue enforcing COVID-19 restrictions — including social distancing rules and mask mandates — even as cases of and deaths attributed to the virus continue a steady two-month decline throughout the country.

Those officials have signaled that the restrictions will not be lifted unless and until an effective vaccine is developed, approved, distributed throughout the country and utilized by enough of the population to create functional herd immunity.

The graph to the right, compiled from this source, shows clearly that the epidemic is fading, and even at its peak never came even close to the terrifying predictions, all now proven to be wrong, of a lot of health officials and junk modeling scientists.

In fact, the numbers continue to show that coronavirus is really nothing more than a bad flu. Like the flu, it is relatively harmless to the young and healthy, who either will show no symptoms from it at all, or might get sick for a week or so and then recover completely. And like the flu, it is only really dangerous to the old and sick, who already have serious health problems which make them vulnerable to any new illness.

Note too that the average age at death from COVID-19 is about 78 years old, which is also identical to the average age expectancy of Americans. In other words, the disease did little to change the number of deaths at all. Even if there were excess deaths this year, they were not much more than we’ve had in previous bad flu seasons, and those additional deaths had no effect on the general population.

For such a disease, you do what we have done for centuries, you protect the weak, and let everyone else live their lives normally. We did not do this this time, and are now suffering from it.

Worse, too many people seem unwilling to accept the reality that the epidemic is ending. Instead, they get outraged by anyone who even suggests such a thing. They have fallen in love with their fear, and want to embrace it, forcing masks and restrictions on everyone forever, just so that they have a false sense of safety.

Unfortunately too many of our fascist governors and health bureaucrats have decided to take full advantage of that panicky fear and use it to gain more power over everyone. As it is said, power corrupts, and absolute power corrupts absolutely. For the past six months we have seen a perfect demonstration of this.

Martian channels within Martian channels

September 21, 2020 2:01 pm Robert Zimmerman

Click for full image.

Whatever caused the meandering canyons on Mars, whether glaciers or liquid water, it was a process that was long-lived and multi-staged, as indicated by today’s cool image to the right, rotated, cropped, and reduced to post here. This photo, taken on June 28, 2020 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), shows a large canyon cutting downward from a high ridgeline to the north. As that canyon begins to flow out out of the mountains and into the plains to the south, a secondary inner channel appears, meandering down the center of the larger canyon.

This canyon is located at 35 degrees south latitude, in the mid-latitude region where scientists have found evidence of a lot of glaciers. In fact, there are some hints of eroded glacial material in the small channels to the west of this main canyon. Also, there appear to be patches of corroding glacial ice on the south-facing slopes of the east and west hills that define the main channel. In the canyon itself however there appear to be few if any glacial-type features.

The overview map below gives the location context.

A UV aurora found on Comet 67P/C-G

September 21, 2020 9:06 am Robert Zimmerman

Using data from Europe’s now completed Rosetta mission to Comet 67P/C-G, scientists have detected evidence that the comet’s interaction with the Sun’s solar wind creates an aurora above the comet in ultra-violet wavelengths.

The data indicate 67P/C-G’s emissions are actually auroral in nature. Electrons streaming out in the solar wind – the stream of charged particles flowing out from the Sun – interact with the gas in the comet’s coma, breaking apart water and other molecules. The resulting atoms give off a distinctive far-ultraviolet light. Invisible to the naked eye, far-ultraviolet has the shortest wavelengths of radiation in the ultraviolet spectrum.

Labeling this phenomenon as an aurora is a bit of hype, as nothing is visible. However, the discovery does tell scientists how this comet’s coma, produced when the comet heats up in its approach to the Sun, interacts with the solar wind, and this in turn can teach them more about that wind, as well as other comets.

Rocks from Vesta on Bennu?

September 21, 2020 8:51 am Robert Zimmerman

Scientists reviewing data of Bennu from OSIRIS-REx have found six very bright boulders that have a make-up similar to that found on Vesta, which suggests they initially came from that asteroid.

The unusual boulders on Bennu first caught the team’s eye in images from the OSIRIS-REx Camera Suite. They appeared extremely bright, with some almost ten times brighter than their surroundings. They analyzed the light from the boulders using the OSIRIS-REx Visible and Infrared Spectrometer instrument to get clues to their composition. … The signature from the boulders was characteristic of the mineral pyroxene, similar to what is seen on Vesta and the vestoids, smaller asteroids that are fragments blasted from Vesta when it sustained significant asteroid impacts.

Of course it’s possible that the boulders actually formed on Bennu’s parent asteroid, but the team thinks this is unlikely based on how pyroxene typically forms. The mineral typically forms when rocky material melts at high-temperature. However, most of Bennu is composed of rocks containing water-bearing minerals, so it (and its parent) couldn’t have experienced very high temperatures. Next, the team considered localized heating, perhaps from an impact. An impact needed to melt enough material to create large pyroxene boulders would be so significant that it would have destroyed Bennu’s parent-body. So, the team ruled out these scenarios, and instead considered other pyroxene-rich asteroids that might have implanted this material to Bennu or its parent.

The make-up of Vesta matches. While these rocks might have been flung from Vesta during an impact there, eventually to settle on the surface of Bennu, Vesta is not the only possibility. We do not have a good census of the asteroids in the solar system. Others whose make-up is not yet determined could be a source, as well as an asteroid that no longer exists, destroyed by a collision long ago.

Regardless, these rocks confirm that in the process of formation in the early days of the solar system, asteroids of all types exchanged material.

First manned Artemis Moon mission might not go to south pole

September 19, 2020 3:59 pm Robert Zimmerman

In order to meet the Trump administration’s 2024 deadline for the first Artemis manned lunar landing, NASA is now considering sending that first mission to an equatorial target, rather than the Moon’s south pole.

The Artemis program landing site issue came up at two separate events with agency leaders this week, beginning with NASA Administrator Jim Bridenstine’s comments to open a digital meeting held by a NASA advisory group called the Lunar Exploration Analysis Group, on Monday (Sept. 14).

“For the first mission, Artemis 3, our objective is to get to the south pole,” Bridenstine said. “But … it would not surprise me if, for example, if we made a determination that the south pole might be out of reach for Artemis 3, which I’m not saying it is or isn’t,” interest in the Apollo sites may win out.

The engineering to get to the polar regions is more challenging, so rather than delay that first mission they are considering simplifying it instead.

The fact remains that Congress has still not funded any Artemis missions beyond the first unmanned and first manned flights, neither of which will land on the Moon. Whether that money will ever be forthcoming really depends entirely on the November election, as well as the success or failure of the upcoming full-up static fire engine test of the SLS first stage.

Mt Wilson Observatory survives wildfire

September 19, 2020 3:47 pm Robert Zimmerman

Firefighters in the past few days managed to stop the wildfire that had come within 500 feet of the historic Wilson Observatory, saving it from destruction.

There were some tense moments on the afternoon of Tuesday, September 15th, as the Bobcat Fire approached within 500 feet of the observatory complex. The battle was on after a 500–1,000 acre spot fire jumped Highway 2 in the Angeles National Forest. Fire crews rallied, cutting fire lines while aircraft flew fire suppression sorties overhead to defend the observatory. By Tuesday night, the worst had passed, though officials stressed that the effort was far from over.

The article also notes the tragic destruction of an amateur telescope observatory in another California wildfire. It will take $30,000 to local club to rebuild.

Les Paul & Mary Ford – There’s no place like home

September 18, 2020 6:01 pm Robert Zimmerman

An evening pause: From the youtube page:

Les and Mary perform “There’s No Place Like Home” with some classic add libbing, especially from Les. Mary Ford was a fine guitarist in her own right and that fact is ably demonstrated here. Watch for when Les goes wild and breaks his high E string. Mary is about to punish him when… Well, watch the video. And, dig those gorgeous 1952 Gibson Les Paul guitars, heavily customized by the master himself. Trivia: Les shattered and almost lost his right arm in a 1948 car crash. Les had the doctors set his elbow at an angle so he could still play guitar but he could never again fully extend his right arm.

Hat tip Wayne DeVette.
