Mission’s to the Moon’s south pole.

The space station startup Voyager Technologies, the lead company in the consortium building the Starlab space station, announced today that is its acquiring the lunar lander startup Astrobotic Technology.

The acquisition directly supports NASA’s Artemis program and Administrator Jared Isaacman’s commitment to a permanent American presence on the Moon by 2028. Voyager intends to accelerate investment to scale Astrobotic’s lunar and reusable rocket programs in support of America’s Moon Base plans.

Following Voyager’s strategic investment in Max Space’s expandable habitat architecture, the company’s capabilities will span the full arc of lunar operation. This includes lunar mission management, communications and propulsion; surface delivery via Astrobotic’s Peregrine and Griffin landers; surface power through Astrobotic’s LunaGrid solar distribution system; long-duration habitation through Max Space; dust mitigation with Voyager’s clear-dust repellent coating; and in-situ resource production.

After three years of delays, Griffin is scheduled to launch on a Falcon Heavy rocket before the end of this year, landing near the south pole with four NASA payloads and Astrolab’s Flip demo rover, as indicated on the map to the right. Astrobotic has launched one previous lander in 2024, but was unable to attempt a landing because of a fuel leak that occurred shortly after launch.

The giant specially designed barge that SpaceX plans to use to transport Starships and Superheavys from Boca Chica to Florida, dubbed “You’ll Thank Me Later”, arrived in Texas last week.

Avid Space, a Starbase streaming outlet part of Labpadre, captured the barge’s arrival, posting images, of which the one to the right is a screen capture. From the first link:

The retrofitted barge Marmac 31, nicknamed “You’ll Thank Me Later” by Elon Musk’s space firm, arrived at the Port of Brownsville last week. It will be used to carry Starship megarockets built at Starbase to Florida and eventually other destinations.

The Starbase-headquartered company has said it would use barges to float the rockets to Florida for launches from there until the Starship factory that it’s building at NASA’s Kennedy Space Center is complete. The company has been in talks with port officials about a 50-year lease for an 83-acre site that would be used as a terminal for the 400-foot-long rockets. Those negotiations are ongoing.

This barge’s arrival in Texas not only makes Starship launches from Florida more likely in the near future, it gives SpaceX the option to buy other launch sites along the Gulf coast, such as that rumored purchase in Louisiana.

Webb detects methane being released by interstellar comet 3I/Atlas

Using the Webb Space Telescope, astronomers have now detected methane in the cloud of material released by the interstellar comet 3I/Atlas as it zipped past the Sun last fall.

The observations were taken using Webb’s MIRI (Mid-Infrared Instrument) on two separate dates as the comet traveled back out of our solar system after whipping around the Sun (post-perihelion). The first observation occurred Dec. 15 to 16, when the comet was about 205 million miles from the Sun. This was followed by a second observation Dec. 27, when the comet was about 236 million miles from the Sun.

For the first time on an interstellar visitor, Webb directly detected methane gas. Methane is highly volatile, meaning it sublimates from solid ice into a gas very easily. Its delayed appearance in comet 3I/ATLAS suggests it was buried below the comet’s top surface layer and protected from sublimation until heat from the comet’s close pass to the Sun reached deeper parts of the icy subsurface. The amount of methane relative to water found is surprisingly high, with few similar analogs in our own solar system.

Webb’s observations also confirmed that comet 3I/ATLAS remains unusually rich in carbon dioxide, releasing far more carbon dioxide relative to water when compared to typical solar system comets.

You can read their peer-reviewed paper here [pdf]. This new data confirms that Comet 3I/Atlas is not from our solar system, as its make-up is sufficiently different from solar system comets to show this. It also gives us a hint as to the solar system it came from. At the same time, the comet’s behavior is remarkably similar to solar system comets, suggesting our solar system evolved much like others.

NASA abandons core module idea for its commercial space station program

8:56 am

The American space stations under development

Bowing to the unanimous opposition by the three most advanced commercial space station startups, NASA official Bethany Stevens yesterday announced that it is abandoning its proposed core module space station concept and returning its commercial space station program to its original plan, whereby the private stations all compete independently.

Industry has provided extensive feedback making the case for a sustainable commercial market in which NASA is one customer among many, along with assurances regarding available transportation capabilities. The industry position will now shape the path forward as NASA proceeds with the original commercial strategy.

Over the coming weeks, NASA will work with stakeholders and industry to refine flexible requirements and acquisition plans, with a draft RFP expected later this month.

The original plan was for the private sector to compete for one or two major construction contracts from NASA. The core module approach, put forth under NASA administrator Jared Isaacman’s leadership in March, instead made them all part of a government space station, like ISS, at least initially. Under that plan the new commercial space stations would attach their first modules to a government-built core module that NASA would first build and own. Isaacman proposed this because he and NASA believed it didn’t have the budget to finance more than one commercial station, and that the agency didn’t think there was sufficient market to make up the difference.

Officials from Vast, Starlab, Axiom and elsewhere all expressed opposition to the core module plan, insisting there was sufficient market to finance their stations, even without NASA. They also opposed the core module plan because it would require major changes in their present designs, and they had great doubt NASA could build that core module quickly enough for their financial purposes.

Isaacman and NASA apparently listened to these objections, and were convinced their idea was a mistake and the industry was right. It is now reviewing its budget and will decide whether it can do what it originally hoped, award two stations a major contract.

Either way, the recent news from all these three stations suggests they are increasingly in a strong position, whether or not they win that NASA contract.

France buys two manned missions from space station startup Vast

8:30 am

Haven-1 with docked Dragon capsule
Artist rendering of Haven-1 with docked
Dragon capsule

In a major deal that solidifies its future space station plans, the space station startup Vast yesterday announced that the French government had agreed to fly two Vast manned missions, first to ISS and then to its Haven-1 single module space station scheduled for launch in 2027.

Today at the Choose France Summit, created by the President of the French Republic, Emmanuel Macron, Vast announced its commitment to establish its European headquarters in Paris and an agreement with the Government of France, for two missions involving two French astronauts: the sixth private astronaut mission to the International Space Station and the Haven-1 test flight, the first crewed mission to Vast’s Haven-1 commercial space station scheduled to launch in 2027.

…Both missions are expected to last approximately two weeks and are planned for 2027, with transportation provided by SpaceX on a Dragon spacecraft launched aboard a Falcon 9 rocket.

For the ISS mission, the astronaut will be rookie Arnaud Prost. For the Haven-1 mission, the astronaut will be veteran Thomas Pesquet, who has flown twice to ISS with a cumulative total of just under 400 days in space.

Vast had previously signed preliminary deals with Lithuania, Colombia, Uzbekistan, Japan, the Czech Republic, and the Maldives, but none of those deals had committed to a manned mission. I had speculated that these nations were waiting for Haven-1 to launch and be declared operational. France has decided not to wait.

This deal is also a major coup for Vast over its space station competitor Starlab, which had previously signed a deal with the European Space Agency and Airbus in an effort to position itself as Europe’s future space station. That deal however had not included any actual missions.

UPDATE: Vast appears to have also signed an agreement with the United Kingdom to fly one of its astronauts to Haven-1. And in this case the astronaut, John McFall, is a former paralympian who lost one leg in a motorcycle accident. This would would make him the first person with disabilities ever to fly in space.

My present ranking of the five stations under development, with Vast now in the lead and Starlab and Axiom tied for second.

Blue Origin CEO: “We will fly again before the end of this year.”

8:01 am

New Glenn launchpad damage
New Glenn launchpad damage. Click for
video source.

In a tweet on X late yesterday, Blue Origin’s CEO David Limp gave a generally positive report of the damage to the launchpad and facilities after last week’s explosion during a static fire test of its New Glenn rocket.

The propellant farm, oxygen, liquid hydrogen and LNG tanks are all in good shape. This is good luck because these are very long lead items. The water tower is also good. The big support tower is damaged, but it can be repaired in place rather than torn down and replaced. The booster “Never Tell Me The Odds” [first stage] and the three GS-2s [upper stages] that were onsite in the integration facility also look good.

…In addition, we had already been working for some time on eliminating our transporter-erector in favor of an alternative vertical conop, and we’ll now go directly to that; so we don’t need a new transporter-erector.

He added that they will proceed quickly in launching the present design of New Glenn, instead of upgrading to the proposed more powerful version, as some in the space community have speculated. He then said what I quote above: “We will fly again before the end of this year.”

While many in the space community appear skeptical of this possibility, I am not. Getting the launchpad rebuilt and workable again based on this report does not seem a gigantic challenge. If the Russians can rebuild their Soyuz pad in just over three months there is no doubt an American company with the financial and technical resources of Blue Origin can do as well if not better. Moreover, except for the replacing the strongback with a vertical mobile transporter, the rest of the work requires no redesign.

The big question however will be tracing the cause of the explosion and fixing that. But even here, I can’t see this taking more than seven months. I might have said so three years ago, before Limp took over from Blue Origin’s previous very bad CEO, but Limp has made a decided effort to quicken Blue Origin’s operational pace. I think he will make this happen.

I also think there is a potential very bright silver lining to this failure. If Limp does what he should, Blue Origin is going to recover from this incident a much better company. By forcing quick action, Limp is going to be able to separate the wheat from the chaff in his staffing, and weed out the bad eggs in the company.

An active galaxy peered at by Webb in the infrared

10:57 am

M77 as seen by Webb
Click for original image.

Cool image time! The false-color infrared image to the right, cropped and reduced to post here, was taken by the Webb Space Telescope as part of a research of “massive, nearby, star-forming galaxies.” It shows Messier 77 (M77), a barred spiral galaxy located 45 million light-years away.

What makes the image cool are the eight diffraction spikes, which are an artifact of Webb and its camera.

Called diffraction spikes, they are created because the intense light from the unresolved AGN is bent (“diffracted”) very slightly at the edges of Webb’s hexagonal mirror panels and around one of the struts that hold up its secondary mirror. This distinctive six-plus-two-pointed pattern is the same for any image taken by Webb. For diffraction spikes to appear, the light source has to be very bright and very concentrated, so they’re most often seen on stars. But in some galaxies, as here, the nucleus is bright and compact enough to make diffraction spikes appear as well.

In the case of M77, the nucleus is especially bright.

At the heart of M77 is a compact region filled with hot gas that handily outshines the rest of the galaxy put together, even overcoming the light-gathering capacity of Webb’s cameras. This is an active galactic nucleus (AGN), and it’s powered by M77’s central supermassive black hole, which is eight million times as massive as our Sun. Gas in the galaxy’s central regions is pulled by the strong gravity into a tight and rapid orbit around the black hole, where it crashes together and heats up, releasing tremendous amounts of radiation.

The result is this very cool image that also highlights a great deal about galaxies and their evolution.

China successfully completes maiden launch of its Long March 12B rocket

9:09 am

China today successfully completed a surprise and unannounced first launch of its new Long March 12B rocket, lifting off from its Jiuquan spaceport in northwest China. Video of the launch (courtesy of BtB’s stringer Jay) can be viewed here.

The launch was unusual in several ways. First, no prelaunch “notices to airmen” were provided to warn them how to avoid the rocket’s flight path. This violates all standard procedures.

Second, this first test flight was also an operational one, placing a batch of Qiafan (SpaceSail) satellites into orbit. This internet constellation is meant to compete with Starlink and Leo, and will eventually have as many as 12,000 satellites in orbit. At present it is aiming to get 648 in orbit by the end of the year. China’s state-run press however did not reveal the number of satellites launched. After the previous launch in mid-May it was estimated there were about 170-180 satellites already in space, suggesting the count has now exceeded 200.

Third, and in line with the first two items, China’s state-run press provided no information about where the rocket’s first stage crashed. Though this rocket uses much less toxic kerosene as its fuel, it is still a big object falling uncontrolled. China says it plans to make the first stage reusable, thus eliminating this problem.

This rocket itself is powerful, designed to put 20 tons in orbit, and gives China an increased capability to put mass into space.

FAA releases more information about SpaceX’s proposed Starfall recoverable capsule

8:41 am

Back in July 2025 it was reported that SpaceX was developing its own recoverable capsule design — dubbed Starfall and comparable in concept to Varda’s capsules.

Under the plan, internally called Starfall, SpaceX’s Starship rocket would bring products such as pharmaceutical components to space in small, uncrewed capsules, said one of the people, who spoke on condition of anonymity because the matter is confidential.

Starship would then deploy the capsules, which would spend time in orbit before reentering the atmosphere, where they could be recovered back on Earth, the person added.

Starfall concept

The FAA has now released an environmental assessment of the design that provides more information, including the first proposed demo missions. The graphic to the right is from that assessment, and provides a simplified illustration of the capsule’s size and shape.

The FAA decision approves two reentries of Starfall capsules in the Pacific Ocean about 1,300 kilometers off the coasts of California and Mexico. The capsules would launch on either Falcon 9 or Starship vehicles, going into orbit before reentry or flying a direct suborbital trajectory to the landing zone.

The capsules are disk-shaped, 0.75 meters tall and 3.1 meters in diameter at the top. The capsules have cold-gas attitude control thrusters but no other propulsion system and do not have the ability to deorbit on their own. The vehicle consists of two parts: a top plate and a heat shield. The top plate is an aluminum structure partially wrapped in an unspecified thermal protection material and weighs 1,400 kilograms. The heat shield is a carbon-fiber structure covered in thermal protection material and also contains nitrogen gas bottles used for the thrusters and other systems. It weighs about 700 kilograms.

The vehicle would slow its descent using a single main parachute, along with pilot and drogue parachutes, with the heat shield jettisoned before splashdown. The FAA documents state that SpaceX will use boats to recover all elements of the spacecraft after splashdown.

No timeline for these tests was provided. It appears SpaceX wants to manufacture and fly these in large numbers, using Starship. It also appears it would be in direct competition with Varda and a host of other startups that have raised capital and are developing their own capsules. In the U.S. Varda, Inversion Space, and Sierra Space have raised money for doing such orbital work. In Europe, The Exploration Company in France, Atmos in Germany, PLD in Spain, Genesis in Croatia, and Space Cargo in Luxembourg have also raised capital. So far, Varda is the only company to successfully fly capsules.

Because all would be depended on other rocket companies to launch their capsules, including SpaceX, Starfall raises some legitimate antitrust questions. SpaceX’s ability to undercut its rivals in this area, as both capsule and rocket provider, would be unmatched, and could easily wipe out all competition.

The competitive need for more launch providers at low cost is becoming increasingly critical.

Space Force awards SpaceX a $4.16 billion satellite contract, the second this week

2:17 pm

The Space Force yesterday awarded SpaceX a $4.16 billion contract to build a satellite constellation to track all flying objects, in addition to the $2.29 billion contract it awarded the company earlier in the week for a different data/communications constellation.

The $4.16 billion Other Transaction Authority agreement is for the Space-Based Airborne Moving Target Indicator (SB-AMTI) program, which aims to develop and field a network of satellites carrying sensors that can continuously detect and follow airborne targets. The deal will allow the Space Force to field an AMTI constellation by 2028, Space Systems Command said in a press release.

Space Force officials also noted that this contract is only the first, and that it does not intend to rely just on SpaceX for this tracking constellation. It intends to use “a highly diversified pool of traditional and non-traditional vendors, each bringing various capabilities” to the system.

Regardless, SpaceX’s satellite division this week won two Pentagon contracts worth more than $6 billion. Not bad work if you can get it.

ULA’s Atlas-5 rocket launches 29 Leo satellites for Amazon

5:26 pm

ULA this evening successfully placed 29 more Leo satellites into orbit for Amazon, its Atlas-5 rocket lifting off from Cape Canaveral Space Force Station in Florida.

ULA is in the process of retiring the Atlas-5 rocket. It now has only seven Atlas-5 rockets left in stock, with one reserved for Leo launches and six for Boeing’s Starliner manned capsule (though there is a good chance some if not all of the Starliner launches will be switched to other payloads). Because its Vulcan rocket, intended to replace Atlas-5, is presently grounded, the company appears to be accelerating Atlas-5 launches, with the last few launches space only about a month apart.

With this launch, Amazon now has 331 Leo satellites in orbit, out of the 1,616 it needs to launch by July to meet its FCC license requirement. It is not going to meet that requirement, because two of the five rockets it contracted for launches are presently grounded (ULA’s Vulcan and Blue Origin’s New Glenn), and only one launch is presently scheduled before July, by Arianespace’s Ariane-6. Furthermore, ULA has only one more Atlas-5 scheduled for Leo, and the ten launches Amazon had purchased from SpaceX are not scheduled. For these reasons, Amazon has asked for a time extension, which the FCC is presently considering.

As this was only the fourth launch by ULA in 2026, the leader board for the 2026 launch race remains unchanged:

63 SpaceX

Firefly announces new stock sale aimed at raising more than a half billion in new funds

11:08 am

The publicly traded rocket/lunar lander company Firefly yesterday announced a new public offering of stock, totalling more than 12 million shares, with the goal of raising more than a half billion for “general corporate purposes.”

Firefly Aerospace (Nasdaq: FLY), a market leading space and defense technology company, today announced the pricing of its public offering of 4,000,000 shares of its common stock and 8,000,000 shares of common stock by certain selling stockholders (the “Offering”) at a public offering price of $48.00 per share. In addition, the selling stockholders have granted the underwriters a 30-day option to purchase up to an additional 1,800,000 shares of common stock at the public offering price, less underwriting discounts and commissions. The Offering is expected to close on June 1, 2026, subject to customary closing conditions.

Firefly intends to use the net proceeds from the Offering for general corporate purposes, including to support growth of core business and recently awarded programs and initiatives. Firefly will not receive any of the proceeds from the sale of shares by the selling stockholders.

Firefly's stock history

Simple math says this offering hopes to raise $576 million dollars, assuming the $48 per share price holds.

The graph to the right shows the full price history of Firefly’s stock since the initial public offering in 2025. After an initial high around $60, the stock sagged to around $20, and only has recovered back into the $40 to $50 range in the past few months. It appears therefore that the company has well timed this new offering.

Curiosity drill samples taken at different elevations show different Martian climates

10:11 am

Core samples used in study
Figure S1 of the study, showing the location
of the core samples. Click for source.

By comparing 20 different Curiosity drill samples taken during the rover’s fourteen years on Mars, scientists have detected hard evidence that the climate in Gale Crater was distinctly different at different elevations, for long periods.

This study shows that hematite can also be a marker of climate changes based on its crystallite sizes and structures, which change under different temperatures. The scientists found that hematite crystallites from higher elevations in Gale Crater were less than 10 nanometers in size, while crystallites from lower locations were generally larger, reaching up to 65 nanometers. These findings aligned with the observations that samples from higher elevations contained both hematite and goethite, while lower elevation samples lacked goethite.

They concluded that, under warmer conditions when the pH of water is neutral or slightly alkaline, goethite can transform into hematite. These warmer conditions also favored an increase in hematite crystallite size in the deeper layers of Gale Crater through a process known as Ostwald ripening, in which smaller crystallites dissolve and contribute to the growth of larger ones. “This can tell you that the top layers were colder and didn’t have enough water, or the water presence was relatively short-lived, so the crystallites didn’t have sufficient time and conditions to grow in size,” said Peretyazhko. “But the lower layers had longstanding warm water that allowed those crystallites to grow.”

The white dots on the map to the right shows the location of the drill samples used, taken along Curiosity’s travels as it climbed Mount Sharp. Overall Curiosity has climbed about 2,500 feet, so the differences found the samples mark the past climate differences between the crater floor and the mountain’s foothills. According to this data, the crater floor had long-standing water in some form, exceeding millions of years. At higher altitudes there was less and less, and it was there for increasingly shorter periods.

As the press release notes, “A unique highlight of this study is that the data comes from Martian samples, rather than from theoretical modeling.” Similar conclusions from earlier Curiosity data required Earth proxies and computer modeling. This result is from hard data from Mars.

South Korean rocket startup Innospace signs up another American satellite launch manager

8:20 am

Less than five seconds after launch
Hanbit-Nano less than five seconds after launch and
just prior to its failure in December 2025.

The South Korean rocket startup Innospace has signed a deal with the American company Ensemble Commercial Services to help obtain satellite contracts and manage the integration and deployment of these payloads.

This marks INNOSPACE’s second launch service distribution agreement in the U.S., following its agreement signed in August last year with Texas-based Arrow Science and Technology, LLC. By securing multiple local partners in the U.S., INNOSPACE plans to enhance customer accessibility in the North American market and accelerate its efforts to identify satellite launch demand and expand sales activities.

Under the agreement, Ensemble will identify potential customers in the U.S., including satellite companies, space startups and research institutions, and connect them with launch service opportunities offered by INNOSPACE for small satellites. Ensemble will also provide regular market updates on the U.S. satellite industry, launch demand trends and potential customer activities, supporting INNOSPACE’s sales activities in the U.S. market.

…With this agreement, INNOSPACE has now secured launch service distribution partners across nine companies in seven countries, including Taiwan, Japan, Italy, the Netherlands, the U.S., Germany and the United Kingdom.

Innospace has made one failed attempt in December 2025 to launch its Hanbit-Nano rocket. It hopes to try again in the third quarter of this year.

Blue Origin’s next New Glenn rocket explodes during static fire test on the launchpad

8:30 pm

New Glenn explosion

During a static fire test of the first stage tonight in preparation for the next launch scheduled for June 4), Blue Origin’s New Glenn rocket exploded just as the test began, destroying the first stage and much of the only launchpad the company has to launch this rocket.

The link above is cued to just before the explosion, shown in a screen capture to the right. BtB’s stringer Jay just sent me a link to a different video view, from farther away but is in some ways as spectacular. According to Blue Origin’s statement, all workers are accounted for, so fortunately there were no fatalities.

The rocket was to launch 48 Amazon Leo satellites. As those satellites were not on the rocket during this test, they are safe and can be launched elsewhere.

The failure will likely prevent any further New Glenn launches by Blue Origin for at least three to six months. Not only does the company have to determine and fix the cause of the failure, it will need to rebuild the launchpad. At best I expect the company will at best manage one test launch before the end of the year.

As for Amazon, this puts it in a big bind. It has only 302 satellites in orbit, but is required to have launched 1,616 by July, according to its FCC license. It has requested a waiver but the FCC has not yet responded. At the moment of the four companies it has hired to launch the satellites, two are now grounded:

  • ULA’s Vulcan rocket: 39 launches [GROUNDED]
  • Blue Origin’s New Glenn rocket: 24 launches (reduced from 27) [GROUNDED]
  • Arianespace’s Ariane-6 rocket: 18 launches (2 completed)
  • SpaceX’s Falcon-9: 13 launches (3 completed)
  • ULA’s Atlas-5 rocket: 8 launches (6 completed)

There is no timeline for when Vulcan and New Glenn will fly again. Arianespace hopes to do four to six more launches in ’26, but only one is an Amazon Leo launch, in June. ULA has six additional Atlas-5 rockets in stock, purchased by Boeing to launch its Starliner capsule to ISS. It is very possible a deal could be arranged with Boeing to switch some of those flights to Leo, since at present there are no plans to launch Starliner in the near future.

All in all, Amazon’s only remaining option is SpaceX. Of the ten unflown launches in the SpaceX contract, none are as yet scheduled. It is now likely Amazon will negotiate a deal with SpaceX to accelerate that schedule. While SpaceX’s own launch manifest is quite crowded (launching its own Starlink constellation), making such a deal difficult, the company has also demonstrated its willingness to help competitors. It launched OneWeb satellites when that company’s deal with the Russians fell through. And it quickly launched those first three Leo missions, faster than anyone else.

This also will impact NASA’s just announced unmanned lunar lander program. One mission planned for this year, Blue Origin’s Blue Moon Mark-1 unmanned lander, was scheduled to launch on a New Glenn. In addition, a second New Glenn was set to launch NASA’s Viper rover next year. Neither will happen as scheduled.

An icy Martian crater filled with brain terrain

11:42 am

An icy Martian crater filled with brain terrain
Click for original image.

Cool image time! The picture to the right, rotated, cropped, and reduced to post here, was taken on March 26, 2026 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what the scientists label an “ice-rich crater fill.”

And yup, that’s what we got. The floor of this 2.8-mile-wide unnamed crater is filled with what planetary scientists have labeled brain terrain, a feature found only on Mars that they associate with the sublimation of near surface ice, but as yet do not fully understand its entire formation process. In the upper right is a full resolution inset of that brain terrain, to give a good sense of its strange nature.

On that floor there are also several small fresh impact craters, as well as older small impacts that have faded almost to obscurity due to that mysterious process forming the brain terrain.

Its iciness of the terrain is also indicated by the rim of the crater, which is distorted as well as blobby. At impact or subsequently the ground here was soft like mud, and thus easy to shape into these cushioned features. Thus, though the rim was almost certainly circular after impact, time and the muddy nature of this ground allows it to get bent and warped.

Nor is it surprising there is near surface ice at this location. We are at 41 degrees south latitude, well away from the dry Martian tropics. This picture simply provides more evidence that once you get above 30 degrees latitude, it will not be hard to find water on Mars.

New long term analysis of solar activity suggests the Sun is undergoing some form of internal structural change

9:36 am

Sunspot activity for the past two cycles
NOAA’s chart of sunspot activity.
Click for the most recent update.

The uncertainty of science: Scientists doing a new analysis of more than forty years of solar data have concluded that some form of “subsurface structural changes associated with successive 11-year [sunspot] cycles” are taking place, with those changes “ever more progressively confined just beneath the solar surface.”

Using almost 40 years of helioseismic data from six telescopes around the world in the Birmingham Solar Oscillations Network (BiSON), the researchers uncovered a gradual change in structure just beneath the surface that has spanned multiple cycles, with the current solar cycle 25 showing particularly strong signatures of these changes.

Lead author Professor Bill Chaplin, from the University of Birmingham, said: “The Sun has its own ‘active biorhythm’ creating rising and falling magnetic activity that shapes space weather. However, traditional surface measures don’t capture the full story – that the Sun may be entering a different mode of behaviour unfolding over decades.

“We have uncovered evidence of systematic changes in the solar activity cycle. Crucially, magnetic activity is becoming more tightly confined near the surface with each cycle.”

The confinement appears to be within the first 600 miles below the surface, which for the Sun is barely skin deep.

In reading the paper [pdf], it is very clear they have detected these changes, but are as yet unable to apply them to any larger fundamental processes. They are observing the Sun change, but don’t know why. It could be simply random fluctuations of behavior, or it could be part of the Sun’s normal behavior related to its magnetic field and the nuclear fusion that makes it burn.

In either case, this lack of deeper understanding means it is impossible as yet to predict what will happen next, or how those future changes will impact us here on Earth.
