Engineers restore Voyager-1 after communications issue

9:20 am

The Voyager missions
The routes the Voyager spacecraft have
taken since launch.

Engineers have now manged to resume normal communications with the Voyager-1 interplanetary probe after it had shut down its main communications channel last month due to low power levels.

Earlier this month, the team reactivated the X-band transmitter and then resumed collecting data the week of Nov. 18 from the four operating science instruments. Now engineers are completing a few remaining tasks to return Voyager 1 to the state it was in before the issue arose, such as resetting the system that synchronizes its three onboard computers.

The X-band transmitter had been shut off by the spacecraft’s fault protection system when engineers activated a heater on the spacecraft. Historically, if the fault protection system sensed that the probe had too little power available, it would automatically turn off systems not essential for keeping the spacecraft flying in order to keep power flowing to the critical systems. But the probes have already turned off all nonessential systems except for the science instruments. So the fault protection system turned off the X-band transmitter and turned on the S-band transmitter, which uses less power.

The S-band transmitter had not been used since 1981, so it took awhile for ground engineers to find the very weak signal. Once found however it was possible to recover operations, though those operations will likely continue for only another year or two. The spacecraft’s power supply is expected to finally run out sometime in ’26 or ’27.

Two launches early today

9:11 am

China and SpaceX successfully completed launches early today.

First, the Chinese pseudo-company Landspace launched a new version of its Zhuque-2 methane-fueled rocket, lifting off from the Jiuquan spaceport in the northwest of China. The mission placed two test satellites into orbit, but more important, the launch tested the rocket’s new fuel-loading systems that copies SpaceX’s, loading the fuel quickly and cooling it to a lower temperature to increase its density and thus allow more to be packed into its tanks.

No word on where the rocket’s first stage crashed inside China.

SpaceX then placed 24 Starlink satellites into orbit, its Falcon 9 rocket lifting off from the Kennedy Space Center in Florida. The first stage completed its fifteenth flight, landing on a drone ship in the Atlantic.

The leaders in the 2024 launch race:

122 SpaceX
55 China
14 Russia
13 Rocket Lab

American private enterprise now leads the rest of the world combined in successful launches 141 to 82, while SpaceX by itself leads the entire world, including American companies, 122 to 101.

Etched terrain on Mars

Etched terrain on Mars
Click for original image.

Today’s cool image is another example of what I call a “What the heck!” image. The picture to the right, simply cropped to post here, was taken on September 22, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

It shows what the scientists label as “etched terrain,” an incredibly twisted and eroded landscape that to me actually defies description. In trying to research what scientists have learned and theorized about this terrain, it appears they think it is material that flowed over older terrain (thus its lack of many craters) that was subsequently eroded by later processes.

Why it eroded so strangely however is not really understood. It could have been caused by near-surface ice sublimated to the surface and thus causing many breaks, but since this terrain is located right on the equator in the dry tropics, it is a very long time since water was present here.

Hubble vs Webb, or why the universe’s secrets can only be uncovered by looking at things in many wavelengths

11:15 am

Hubble view of Sombrero galaxy
Click for original image.

Time for two cool images of the same galaxy! The picture above shows the Sombrero Galaxy as taken by the Hubble Space Telescope in 2003. The picture below is that same galaxy as seen by the Webb Space Telescope in the mid-infrared using false colors. From the press release:

In Webb’s mid-infrared view of the Sombrero galaxy, also known as Messier 104 (M104), the signature, glowing core seen in visible-light images does not shine, and instead a smooth inner disk is revealed. The sharp resolution of Webb’s MIRI (Mid-Infrared Instrument) also brings into focus details of the galaxy’s outer ring, providing insights into how the dust, an essential building block for astronomical objects in the universe, is distributed. The galaxy’s outer ring, which appeared smooth like a blanket in imaging from NASA’s retired Spitzer Space Telescope, shows intricate clumps in the infrared for the first time.

Researchers say the clumpy nature of the dust, where MIRI detects carbon-containing molecules called polycyclic aromatic hydrocarbons, can indicate the presence of young star-forming regions. However, unlike some galaxies studied with Webb … the Sombrero galaxy is not a particular hotbed of star formation. The rings of the Sombrero galaxy produce less than one solar mass of stars per year, in comparison to the Milky Way’s roughly two solar masses a year. Even the supermassive black hole, also known as an active galactic nucleus, at the center of the Sombrero galaxy is rather docile, even at a hefty 9-billion-solar masses. It’s classified as a low luminosity active galactic nucleus, slowly snacking on infalling material from the galaxy, while sending off a bright, relatively small, jet.

In infrared the galaxy’s middle bulge of stars practically vanishes, exposing the weak star-forming regions along galaxy’s disk.

Both images illustrate the challenge the universe presents us in understanding it. Basic facts are often and in fact almost always not evident to the naked eye. We always need to look deeper, in ways that at first do not seem obvious. This is why it is always dangerous to theorize with certainty any explanation too soon, as later data will always change that explanation. You can come up with an hypothesis, but you should always add the caveat that you really don’t know.

By the way, this concept applies not just to science. Having absolute certainty in anything will almost always cause you to look like a fool later. Better to always question yourself, because that will make it easier for you to find a better answer, sooner.

We need only look at the idiotic “mainstream press” during the months leading up to the November election to have an example of someone with certainty who is now exposed as an obvious fool.

Firefly’s Blue Ghost lunar lander now targeting mid-January launch window

10:08 am

Landing sites on Moon

According to a media update from NASA yesterday, Firefly’s Blue Ghost lunar lander now targeting mid-January launch window for its unmanned mission to the Moon.

A six-day launch window opens no earlier than mid-January 2025 for the first Firefly Aerospace launch to the lunar surface.

The Blue Ghost flight, carrying 10 NASA science and technology instruments, will launch on a SpaceX Falcon 9 rocket from Launch Complex 39A at the agency’s Kennedy Space Center in Florida. Media prelaunch and launch activities will take place at NASA Kennedy.

The first quarter of 2025 will be a busy time for unmanned missions to the Moon. In addition to Firefly’s mission, the American startup Intuitive Machines also hopes to launch its Athena lander to the Moon’s south pole in February. Though it will launch after Blue Ghost, it will get to the Moon first, as it is taking a more direct week-long route compared to Blue Ghost’s 45-day journey. In addition, the Japanese company Ispace is targeting its own January launch for its Resilience lander.

If all three lift off as planned, there will be three landers heading for the Moon in early 2025.

Engine for Japan’s new Epsilon-S rocket explodes during static fire test

9:36 am

For the second time in a row an engine for Japan’s new Epsilon-S rocket has exploded during a static fire test.

The test was conducted inside of the restricted area at Japan’s Tanegashima Space Center in southwestern Japan, and the Japan Aerospace Exploration Agency is investigating, Chief Cabinet Secretary Yoshimasa Hayashi told reporters.

An Epsilon project manager, Takayuki Imoto, told an online press conference from Tanegashina that the explosion occurred 49 seconds into the planned two-minute test, causing fire and scattering broken parts of the engine and damaging the facility.

The Epsilon-S is being built by Japan’s space agency JAXA. It is intended to replace the solid-fueled Epsilon rocket that was initially conceived in 2013 to lower launch costs and provide JAXA with a rocket that could complete with the many new smallsat rocket startups worldwide. That rocket however only launched six times and never achieved its goals. JAXA had been targeting March for the first launch of Epsilon-S, but that is now unlikely, especially considering these two engine failures during tests.

France to resume suborbital launches at French Guiana

9:14 am

Now that France’s space agency CNES has taken the management of its French Guiana spaceport back from the European Space Agency’s Arianespace government company, it has been moving to make the spaceport more attractive to multiple future launch customers. Previously it announced that it is offering launchpads to multiple new rocket startups. Now it has announced that has signed a contract with the French startup Optus Aerospace to reopen its closed suborbital launchpad for the first time in decades.

Officially inaugurated in 1968, the Ensemble de Lancement Fusées-Sondes (ELFS) launch complex hosted the Guiana Space Centre’s first launch on 9 April 1968, with a Véronique sounding rocket that reached an altitude of 113 kilometres. Between 1968 and 1992, more than 350 sounding rockets were launched from the facility.

On 25 November, CNES announced that it had signed a contract with Opus Aerospace to use the ELFS facility for the launch of its Mésange rocket.

In other words, under the control of a government entity, Arianespace, which also controlled all European launches for decades, the variety of launches declined. As soon as control was lifted from this government monopoly however the possibilities expanded quickly.

SpaceX wins launch contract for Dragonfly mission to Titan

8:58 am

NASA yesterday announced that it has awarded the launch contract for sending its Dragonfly mission to Titan to SpaceX’s Falcon Heavy rocket.

The firm-fixed-price contract has a value of approximately $256.6 million, which includes launch services and other mission related costs. The Dragonfly mission currently has a targeted launch period from July 5, 2028, to July 25, 2028, on a SpaceX Falcon Heavy rocket from Launch Complex 39A at NASA’s Kennedy Space Center in Florida.

Dragonfly is a truly cutting edge mission. Though we have relatively limited information about Titan’s atmosphere and the environment on its surface, it will attempt to fly there like a helicopter, landing and taking off multiple times.

And though there are certainly additional costs required for such a mission, that quarter-billion dollar contract price probably triples what it normally costs SpaceX for a Falcon Heavy mission. Even if it requires the expending of all three first stages, the company is almost certainly getting a big windfall from this deal.

Martian mountains amidst a deep sea of sand

11:17 am

Overview

A Martian mountain surrounded by a sea of sand
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on July 9, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). The white dot on the overview map above marks the location, inside the deep enclosed and very large 130-mile-wide depression dubbed Juventae Chasma.

The mountain in the picture raises above the sand sea that surrounds it from 1,000 to 2,300 feet, depending on direction, as the downhill grade of the sand sea is to the east. Thus, on the west the mountain rises less, while on the east the height is the greatest.

The inset illustrates the extent of the sand sea. It covers the ground for many miles in all directions. The way the sand surrounds these mountains suggests the prevailing winds blow from the west to the east. In fact, the facts suggest that this sand is volcanic ash that was blown into Juventae from many eruptions that occurred over time to the west, where it got trapped. The wind and gravity deposited the sand into the 20,000 to 25,000-foot-deep chasm, where the wind was insufficient to lift it out again.

One wonders how deep that sand sea might be. The lack of any surface features at all suggests it could be quite deep, burying everything but the highest peaks. In fact, if a geologist could drill a core through that sand I suspect he or she might be able to document the entire eruption history of much of Mars.

Italy to resume use of its San Marco spaceport off the coast of Kenya

9:21 am

Italy's offshore San Marco spaceport
Click for full map.

Italy has now decided to re-open its long unused San Marco spaceport facility off the coast of Kenya, resuming launches from its off-shore launch platform.

During its active life beginning in 1967 a total of eight launches occurred from this site, with the last flight occurring in 1988.

In late 2023, the Minister of Enterprise and Made in Italy, Adolfo Urso, first proposed reopening the facility for rocket launches. While unsubstantiated by other sources, local publication MalindiKenya.net reported at the time that the move would be used to create an “ideal launch base for the Italian Vega launcher, thus avoiding paying France for the use of the French Guiana base.”

In October 2024, during a presentation just before the 75th International Astronautical Congress kicked off, Minister Urso explained that the country had decided to move ahead with its plans to once again launch rockets from the Luigi Broglio Space Center.

The present plans will have the site managed by the Kenya Space Agency, established in 2017, with Italy providing the rockets and satellites, all of which are expected to be smallsats. It appears that the rocket company Avio, which builds the Vega-C rocket, might be aiming to use this site as an commercial launchpad, thus allowing it to bypass the French-run French Guiana spaceport. Located close to the equator and on the coast, this site would offer satellite companies a very wide range of orbits.

Launches galore in the past twelve hours

8:49 am

The past twelve hours was quite busy at spaceports worldwide, with two American companies completing three different launches from three different spaceports, while China added one of its own.

First China launched two radar-mapping satellites, its Long March 2C rocket lifting off from its Jiuquan spaceport in northwest China. No word on where its lower stages, that use very toxic hypergolic fuels, crashed inside China. Though this launch was first, it actually took place in the early morning of November 25th, in China.

Next, Rocket Lab completed two launches, though one was not an orbital flight. First it completed its second of four planned launches of its HASTE suborbital version of its Electron rocket, lifting off from Wallops Island in Virgina. HASTE had been quickly improvised by the company when it realized there was a real market for hypersonic suborbital testing, and Electron could be refitted for that purpose. This launch actually occurred prior to the Chinese launch.

Then Rocket Lab launched five more satellites for the satellite company Kineis, the third of five, its Electron rocket lifting off from one of its two launchpads in New Zealand.

Finally, SpaceX in the early morning of November 25th launched 23 Starlink satellites, its Falcon 9 rocket lifting off from Cape Canaveral in Florida. The first stage completed its thirteenth flight, landing on a drone ship in the Atlantic.

The leaders in the 2024 launch race:

121 SpaceX
54 China
14 Russia
13 Rocket Lab

American private enterprise now leads the rest of the world combined in successful launches 140 to 81, while SpaceX by itself leads the entire world, including American companies, 121 to 100.

Unloading of new Progress docked to ISS delayed due to “toxic smell”

10:02 pm

The unloading of cargo from the new Progress freighter that docked to ISS on November 23, 2024 halted immediately after hatch opening because of a “toxic smell” detected by the Russian astronauts.

The crew then proceeded with air leak checks in the docking port, but after opening the hatch between Poisk and Progress, it had to be closed immediately due to toxic smell and possible contamination hazard in the form of droplets, according to communications between the US mission control in Houston and the ISS crew in late hours Moscow Time on November 23.

Various systems aboard the ISS were activated to scrub the station’s atmosphere from possible contamination, while the hatch of the Poisk module leading into the pressurized cargo compartment of the Progress M-29 spacecraft remained closed. In particular, the Trace Contaminant Control Sub-assembly, TCCS, was turned on aboard the US Segment. The Russian crew was also reported donning protective equipment and activating an extra air-scrubbing system aboard the Russian Segment, which operated up to a half an hour.

By the end of today mission controllers from both Russian and the U.S. declared the air cleared and normal, and have begun unloading operations.

The cause remains unexplained.

New Glenn on the launchpad and vertical for the first time

The first completely assembled New Glenn, on the launchpad
The first completely assembled New Glenn,
on the launchpad

Blue Origin’s first New Glenn rocket to be fully stacked and ready for launch was finally placed vertical on its Cape Canaveral launchpad late November 21, 2024.

For the first time, the company placed a fully integrated, flight-capable rocket on the launch pad Thursday evening. The company rolled the rocket out of the hangar at Launch Complex 36 (LC-36) earlier. A static fire test with the full 98-meter-tall (320 ft) rocket is forthcoming, though a specific date hasn’t been announced.

…The upcoming integrated static fire test would be the first time that Blue Origin fuels a full-assembled. flight-ready New Glenn rocket. It previously conducted a static fire test of its upper stage, which saw a 15-second burn of the two BE-3U engines.

The picture to the right was released by the company that night.

No launch date has been announced. The present payload for this launch is the company’s own Blue Ring orbital tug on a Pentagon-supported test flight. The original payload, two smallsat NASA Mars orbiters built by Rocket Lab, had to be pulled when Blue Origin’s generally leisurely approach meant that it was unable to get the rocket ready in time to meet the October launch window.

That leisurely approach to business will have to end if Blue Origin really wants to compete in today’s modern aerospace industry.

Distinct gully draining the side of a Martian crater

Distinct gully in crater on Mars
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on August 20, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). The science team labels the entire picture simply as “gully,” obviously referring to that distinct and somewhat deep hollow in the middle of the picture.

Most gullies that have been found on Mars tend to look more eroded and rougher than this hollow. Here, it appears almost as if the process that caused this gully occurred relatively recently, resulting in its sharp borders that have not had time to crumble into softer shapes.

The crater interior slope is about 1,500 feet high. Whatever flowed down it however did not do it in an entirely expected manner. As it flowed it curved to the west, so that the impingement into the glacial material that fills the crater floor is to the west of the gully itself. Either that, or that impingement was caused by a different event at a different earlier time.

Starship gets contract to deliver Lunar Outpost’s rover to Moon

11:10 am

Capitalism in space: The lunar lander version of SpaceX’s Starship has won a contract from the startup Lunar Outpost to deliver its manned rover to the Moon.

The Colorado company announced Nov. 21 that it signed an agreement for SpaceX to use Starship to transport the company’s Lunar Outpost Eagle rover to the moon. The companies did not disclose a schedule for the launch or other terms of the deal.

This announcement is less a new deal for SpaceX and more an effort to convince NASA to award Lunar Outpost the full contract to build the rover. In April 2024 Lunar Outpost was one of three companies chosen by NASA to receive initial development grants to design their proposed manned lunar rovers. NASA expects to award the full contract, worth potentially up to $4.6 billion, to one of these three companies later this year, after seeing their preliminary designs. It wants to choose two, but at present says budget limitations make that impossible.

ESA and JAXA sign agreement to increase cooperation and accelerate development of Ramses mission to Apophis

10:18 am

The new colonial movement: The European Space Agency (ESA) and Japan’s own space agency JAXA on November 20, 2024 signed a new cooperative agreement to increase their joint work on several missions, the most important of which is the proposed Ramses mission to the potentially dangerous asteroid Apophis during its 2029 close fly-by of Earth.

Two agencies agreed to accelerate to study potential cooperation for ESA’s Rapid Apophis Mission for Space Safety (RAMSES) which aims to explore the asteroid Apophis that will pass close to our planet on 13 April 2029, including but not limited to provision of thermal infrared imager and solar array wings as well as possible launch opportunities.

The two countries are already working together on two different planetary missions, the BepiColombo mission to Mercury and the Hera mission to the asteroid Dymorphos. Both are on their way to their targets. This new agreement solidifies the commitment of both to make sure Ramses is funded, built, and launched in the relatively short time left before that 2029 Earth fly-by. At the moment the ESA has still not officially funded it fully.

NASA once again gambling on the lives of its astronauts for political reasons

10:07 am

Orion's damage heat shield
Damage to Orion heat shield caused during re-entry in 2022,
including “cavities resulting from the loss of large chunks”

NASA this week began the stacking one of the two strap-on solid-fueled boosters that will help power SLS on the Artemis-3 mission, still officially scheduled for September 2025 and aiming to send four astronauts around the Moon.

A NASA spokesperson told Ars it should take around four months to fully stack the SLS rocket for Artemis II. First, teams will stack the two solid-fueled boosters piece by piece, then place the core stage in between the boosters. Then, technicians will install a cone-shaped adapter on top of the core stage and finally hoist the interim cryogenic propulsion stage, or upper stage, to complete the assembly.

At that point the rocket will be ready for the integration of the manned Orion capsule on top.

The article at the link sees this stacking as a good sign that NASA’s has solved the Orion capsule’s heat shield issue that occurred during the unmanned return from the Moon on the second Artemis mission. The image to the right shows that heat shield afterward, with large chunks missing. Though it landed safely, the damage was much much worse than expected. At the moment NASA officials have said it has found the root cause, but those officials also refuse to say what that root cause is, nor how the agency or Orion’s contractor Lockheed Martin has fixed it.

China’s plan to land astronauts on the Moon

9:31 am

Mengzhou as of 2023
Click for source.

The new colonial movement: China’s state-run press yesterday revealed the basic flight plan its space program will use to land astronauts on the Moon in 2030.

China’s first manned lunar mission will begin with the launch of the Lanyue lunar lander aboard the country’s new heavy carrier rocket [the Long March 10], and Lanyue will then await the subsequent arrival of the Mengzhou manned spacecraft in space. Mengzhou will be poised for its rendezvous with Lanyue in lunar orbit, at which time the astronauts will transfer into the lander.

The lander will then separate and descend to the moon’s surface. Upon the completion of their lunar exploration, the astronauts will return to lunar orbit in the lander’s ascent stage. This stage will involve re-docking with the spacecraft, and will mark the beginning of the astronauts’ journey back to Earth.

This plan is a variation of the Apollo approach, but rather than sending the ascent/descent capsule and lunar lander on the same rocket, China will launch them separately and have them rendezvous in lunar orbit.

Mengzhou is intended to be a larger and reusable replacement for the Shenzhou capsules China is presently using to transport its astronauts to and from its Tiangong-3 space station. Unlike Shenzhou, which appears to be an upgrade of Russia’s Soyuz capsules, Mengzhou instead appears more conelike, as shown by the mockup image to the right, first revealed in 2023.

The next two Vulcan launches for the Pentagon slip to 2025

9:14 am

Both the Space Force and ULA have now admitted that the next two Vulcan launches, which both had hoped to launch before the end of this year, have now been delayed until 2025, and that Vulcan remains uncertified as yet by the military for its launches.

The United Launch Alliance’s Vulcan will not be able to conduct two planned national security missions on its launch manifest for this year after delays with certifying the heavy-lift rocket. The comments came hours after a Space Force official cast doubt that the missions could be completed before the end of 2024.

ULA launched its second certification flight in October, roughly a month behind schedule, following a first flight in January that was nearly four years behind schedule. The Space Force is still assessing data from the October launch in partnership with ULA.

The military had said if ULA completed two Vulcan successful launches it would approve Vulcan for these launches. Though the second launch got its payload to its correct orbit, during launch the nozzle on one of its strap-on solid-fueled boosters fell off. Though officials keep saying they expect certification anyway, that certification has not happened. It appears right now that the military won’t do so until the investigation into the problem is completed and a fix is installed.

At the moment the only rocket company that can launch large payloads for the Pentagon is SpaceX. Though that company has not gouged the military in bidding (though it it could) this is not a good situation. The military wants options and redundancy, not simply to save money, but to give it flexibility. It needs ULA and Blue Origin to finally deliver their rockets.

November 19-20, 2024 Zimmerman/Space Show podcast

5:13 pm

My long appearance on the Space Show with David Livingston on November 19, 2024 is now available here.

I list the show as extending into November 20th because we had a sound glitch an hour into the November 19th live stream, forcing us to prematurely end the broadcast. David got the technical problem fixed the next day and we then aired another thirty or so minutes to complete the topics we had been discussing the day before. He then pieced the two sections together to produce this podcast.

Enjoy. Of course the central topic was the Starship/Superheavy flight that day, but we also touched on the consequences of a new Trump administration on SpaceX, NASA, SLS, and Artemis. I also provided an overview of the space efforts in Europe, India, Russia, and China.

Starship splashing down vertically
Starship splashing down vertically in the
Gulf of Mexico on November 19, 2024

Yesterday radio host Robert Pratt sent me a news story from a Texas newspaper, the Texas Tribune, which attempted quite surprisingly to capture fairly the local response to the most recent Starship/Superheavy test launch out of Boca Chica on November 19, 2024.

The reporter, Bernice Garcia, clearly made it a point to talk to a lot of people, especially those who came out to see the launch. As a result, she showed that in general, no matter what people felt about Donald Trump or Elon Musk, the local population was almost entirely in favor of SpaceX’s efforts there. For example:

Sanchez was slightly concerned about [the rocket’s sonic booms] but believed the benefits of jobs created by SpaceX was worth the risk. “They know what they’re doing,” Sanchez said.

But his favorable opinion of Musk’s company did not extend to Trump. A naturalized citizen who gained amnesty under the Reagan administration, Sanchez didn’t view Trump’s immigration policies as logistically sound. “If you throw those people out, who’s going to work?” Sanchez said. “You don’t see a white man laboring out in the sun. On the other hand, Mexicans, foreigners, people from other countries –– that’s why they come here, to work.”

While the story found locals with a whole range of opinions about Trump, both positive and negative, it only quoted one person who was hostile to SpaceX, and that quote and person tells us a great deal about the bankrupt nature of that opposition:

Gophers dropped near Mt St. Helens for one day cause a gigantic bloom of plant life 40 years later

12:02 pm

In 1982, two years after the Mt. St. Helens volcanic eruption, scientists decided to do an experiment: They dropped six gophers into one meter square enclosures near the eruption with the hope the animals’ digging for one day would bring good soil close enough to the surface to encourage the return of plant life.

The results forty-plus years later:

Six years after their trip, there were over 40,000 plants thriving where the gophers had gotten to work, while the surrounding land remained, for the most part, barren. Studying the area over 40 years later, the team found they had left one hell of a legacy. “Plots with historic gopher activity harbored more diverse bacterial and fungal communities than the surrounding old-growth forests,” the team explained. “We also found more diverse fungal communities in these long-term lupine gopher plots than in forests that were historically clearcut, prior to the 1980 eruption, nearby at Bear Meadow.”

“In the 1980s, we were just testing the short-term reaction,” Allen added. “Who would have predicted you could toss a gopher in for a day and see a residual effect 40 years later?”

You can read the published paper here. It appears the gophers’ action activated the microbiological life in the soil, which in turn made it easier for plant life to return.

The potential benefits of this research is gigantic, especially in areas that have been devastated by any number of natural and man made disasters.
