Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on July 14, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), showing the very bottom section of the long and endlessly deep south slopes of Valles Marineris, the largest known canyon in the solar system.

The many layers here are likely evidence of repeated volcanic flood lava events, over several billion years, after which the canyon formed.

On the overview map above the black dot in the southeast section of the area of the canyon dubbed Melas marks this location. The picture’s northeast corner is essentially the floor of Valles Marineris. From this point the elevation gain to the southwest corner of the picture 3.5 miles away is about 3,300 feet.

The rim itself however is far far higher, about fifty miles farther to the southwest and climbing about 22,000 feet more. Along those fifty miles you’d have to also climb over two intervening mountain ranges, one about 4,000 feet high and the second about 6,000 feet high.

Valles Marineris is big, so big it is hard to imagine a canyon this size. It makes many moutain ranges on Earth seem small.

Ingenuity completes 60th flight, sets new speed record

September 27, 2023 12:33 pm Robert Zimmerman

Click for interactive map.

On September 25, 2023 the Mars Helicopter Ingenuity completed its 60th flight on Mars, traveling 1,116 feet in 133 seconds at an altitude of 53 feet.

In doing so, the helicopter set a new speed record, approximately 17.9 miles per hour. As has become somewhat routine, it flew for slightly farther and longer then its original flight plan, probably because it needed a bit of extra time to find a safe landing spot.

The overview map above shows in green the flight’s approximate distance and route, with the red dotted line indicating the future planned route of the rover Perseveranc. Since the Perseverance science team has not yet updated its rover/helicopter location map to indicate the exact landing spot, I have roughly marked it based on the distance traveled and its intended direction, to the northwest.

The blue dot marks Perseverance’s present location, where it is presently drilling to obtain anotther core sample.

Iran launches spy satellite

September 27, 2023 11:23 am Robert Zimmerman

Iranian officials today confirmed the successful launch of its Qased rocket, placing a classifed Noor spy satellite into orbit.

The Space Force confirmed this announcement, tracking two objects (one likely the satellite and the other the upper stage) in a 442 by 456 kilometer orbit with a 60.0 degree inclination. That steep inclination will allow the satellite to cross over two thirds of the Earth’s surface.

This was Iran’s first launch in 2023, and third launch of this type spy satellite and rocket since 2020. The leaders in the 2023 launch race remain the same:

68 SpaceX
44 China
13 Russia

Expect long delays after third Artemis mission

September 27, 2023 10:24 am Robert Zimmerman

Link here. The article outlines from a different perspective the many problems faced by NASA’s Artemis program, specifically related to its SLS rocket.

First, that fourth Artemis mission will require a larger first stage, which is far behind schedule and should not be ready until late 2028 (though I predict at least one to two years beyond that date).

Second, that larger upper stage will require completion of a new mobile launcher platform, replacing the mobile launcher now in use that cost about a half billion and will only be used three times. The new launcher platform however is also behind schedule and overbudget. Its completion is not expected until 2027 (though I predict at least one year beyond that date).

Thus, even if the third Artemis mission flies in 2026, as presently scheduled, it will be at least two years before the fourth can fly, but more likely the gap will be three to four years.

Everything related to NASA’s SLS rocket is a mess. If the people running our government had brains, they would immediately dump it and do everything they can to speed development of Starship/Superheavy, which has a better design, is reusuable, is more powerful, has greater capabilities, and most important of all, will be able to fly frequently and quickly at a very low cost, something that SLS will never be able to do.

Unfortunately, the people running our government have no brains, or to be more precise, refuse to use them because of their own selfish petty interests. SLS will go on, wasting billions. And the effort to squelch Starship/Superheavy will also continue, because these petty federal officials can’t have a private company show them up. No way! It must be their way, or the highway!

Nearest supernova in a decade confirms such stars lose mass prior to exploding

September 27, 2023 10:03 am Robert Zimmerman

taken by the Gemini North telescope in Hawaii.

Astronomers making a detailed analysis of the data from the nearest supernova in a decade, SN 2023ixf and located in the Pinwheel Galaxy only 20 million light years away, has confirmed what other research had suggested, that such stars lose significant mass prior to exploding.

Within hours of going supernova, core-collapse supernovae produce a flash of light that occurs when the shock wave from the explosion reaches the outer edge of the star. SN 2023ixf, however, produced a light curve that didn’t seem to fit this expected behavior. To better understand SN 2023ixf’s shock breakout, a team of scientists led by CfA postdoctoral fellow Daichi Hiramatsu analyzed data from the 1.5m Tillinghast Telescope, 1.2m telescope, and MMT at the Fred Lawrence Whipple Observatory, a CfA facility located in Arizona, as well as data from the Global Supernova Project— a key project of the Las Cumbres Observatory, NASA’s Neil Gehrels Swift Observatory, and many others. This multi-wavelength study, which was published this week in The Astrophysical Journal Letters, revealed that, in sharp contradiction to expectations and stellar evolution theory, SN 2023ixf’s shock breakout was delayed by several days.

“The delayed shock breakout is direct evidence for the presence of dense material from recent mass loss,” said Hiramatsu, adding that such extreme mass loss is atypical of Type II supernovae. “Our new observations revealed a significant and unexpected amount of mass loss— close to the mass of the Sun— in the final year prior to explosion.”

The press release overstates the surprise of this discovery. Research in the last two decades of massive stars that are thought to be the progenitors of supernovae has shown that they lose mass in great amounts during eruptions. It was therefore not that surprising that this star experienced its own eruption prior to going supernova.

India successfully tests upgraded upper stage engine for manned mission

September 27, 2023 9:49 am Robert Zimmerman

India’s space agency ISRO has now successfully completed full power static fire engine tests of a more power version of the upper stage engine used by the most powerful version of its GSLV rocket, the LVM3, thus preparing it to launch that nation’s first manned mission, dubbed Gaganyaan.

On September 22, 2023, this test was conducted at the state-of-the-art test facility located at IPRC, Mahendragiri. During this test, the CE20 engine operated at the coveted 22-tonne thrust level for a duration of 670 seconds. Both the engine and the testing facility performed flawlessly, meeting all the performance parameters.

ISRO is still targeting 2024 for the first manned mission, but that target remains somewhat uncertain, though less so as one-by-one the agency completes these performance tests successfully.

Small group of astronomers call for renaming the Magellanic Clouds, accusing Magellan of racism

September 27, 2023 9:38 am Robert Zimmerman

They’re coming for you next: A new group of about fifty astronomers are now demanding that the Magellanic Clouds in the southern hemisphere be renamed because they don’t like it that Magellan was both a man of his time and also a white European explorer.

Magellan’s name is not fitting, astronomer Mia de los Reyes and colleagues argue. The leader of the first expedition to successfully circle the globe, Magellan enslaved and killed Indigenous people encountered on the voyage, which set out from Spain in 1519.

“Because we’re naming things in the night sky, which belongs to everyone, we think that it’s important to have names that reflect all of humanity,” says de los Reyes, of Amherst College in Massachusetts. She calls for the name change in an opinion piece published September 12 in Physics. Magellan’s voyage helped pave the way for Spanish colonialism in South America, Guam and the Philippines, says de los Reyes, who is Filipino American. “Many people see Magellan as a villain in the Philippines.”

No matter that Magellan was a great explorer who sacrificed his life to finally prove without doubt that the Earth was a sphere. No matter that he was the first person to document the existence of the Magellanic Clouds, which is why they are named for him. He was white and a European, and thus his place in history must be cancelled forever.

It also should not matter that the claims against Magellan are partly true, though magnified greatly into a slander by the use of Marxist terms. His prime mission was one of exploration, and the natives he kidnapped were taken not for purposes of slavery but to provide further documentation of what he had discovered.

No human being is perfect, and if we accept these demands to measure the past by these perfect standards we will have to cancel all history forever.

Which by the way is the real point. These radicals aren’t really interested in honoring the right people and taking honor away from the wrong people. What they want to do is to discredit all past Western history, and replace it with a Marxist fantasy that makes believe the achievements of European and Western Civilization never happened.

Giant Magellan Telescope begins fabricating its seventh mirror

September 27, 2023 9:23 am Robert Zimmerman

The fabrication of the seventh and last mirror for the Giant Magellan Telescope (GMT) has begun, with its completion and installation expected before the end of the decade.

In the project’s latest development, the Richard F. Caris Mirror Lab at another founding project partner, the University of Arizona, closed the lid on nearly 20 tons of the purest optical glass inside a one-of-a-kind oven housed beneath the stands of the university’s football stadium. The spinning oven will heat the glass to 1,165 degrees Celsius, so that as it melts, it is forced outward to form the mirror’s curved paraboloid surface. Measuring 8.4-meters in diameter—about two stories tall when standing on edge—the mirror will cool over the next three months before moving into the polishing stage.

Once assembled, all seven mirrors will work in concert as one monolithic 25.4-meter mirror—a diameter equal to the length of a full-grown blue whale—resulting in up to 200 times the sensitivity and four times the image resolution of today’s most advanced space telescopes.

A decade ago it was expected that this telescope in Chile would follow the Thirty Meter Telescope (TMT), while also working in parallel with it, with TMT covering the northern hemisphere and GMT covering the southern hemisphere. Now GMT is likely to forever work alone, as TMT remains blocked in Hawaii by the government and anti-western, anti-white protesters, and will likely never be built.

Three astronauts return to Earth safely, completing 371 day mission

September 27, 2023 9:13 am Robert Zimmerman

One American, Frank Rubio, and two Russians, Sergey Prokopyev and Dmitri Petelin, early today safely returned to Earth in their Russian Soyuz capsule, completing the longest mission yet on ISS, 371 days, and the third longest human mission ever.

The mission was the longest by accident. It was originally supposed to be a standard six month tour, but was extended to a year when the Soyuz capsule they came in developed a leak in its coolant system and had to be replaced.

The previous record for an American in space of 355 days was set by Mark Vande Hei last year. This new year-long mission is only exceeded by two Russian missions on Mir, Valeri Polykov’s 439 day mission in 1994-1995, and Sergei Avdeyev’s 381 day mission in 1998-1999.

Sierra Space raises another $290 million in private investment capital

September 26, 2023 2:26 pm Robert Zimmerman

Sierra Space today announced that during its most recent funding round it successfully raised another $290 million in private investment capital, bringing the total capital it has raised to $1.7 billion.

The round is co-led by Japan’s largest bank, MUFG, Kanematsu Corporation, a Japanese trading company and Tokio Marine & Nichido Fire Insurance, Japan’s largest property and casualty insurance group with participation from Sierra Space’s existing investors. The companies are already participating in a JAXA (Japanese Aerospace Exploration Agency) study to explore how to conduct activities in LEO as the ISS approaches the end of service.

These Japanese partnerships act to strengthen Sierra’s already strong links to Japan, including ongoing negotiations to land its Dream Chaser reusable mini-shuttes at Oita Airport, as well as partnership deals with Kanematsu, Japan Airlines and Mitsubishi.

This successful fund-raising round suggests strongly that the company’s plans to finally have its first Dream Chaser cargo shuttle, Tenacity, ready to fly in December might actually happen. Or at least, that plan acted to convince these investors to pony up some cash.

Pushback: Federal court rules against ban of Christian student group by San Jose Unified School District

September 26, 2023 2:05 pm Robert Zimmerman

San Jose Unified School District: Where Satan
worshipers are welcomed and Christians banned.

They’re coming for you next: On September 13, 2023 the Federal Ninth Circuit Court overturned a ban of the student group, the Fellowship of Christian Athletes (FCA), by San Jose Unified School District, stating that the district cannot allow some groups it agrees with to meet on campus but ban religious groups it dislikes.

The history:

In April 2019, controversy erupted at the San Jose Unified School District’s Pioneer High School in California over a Fellowship of Christian Athletes requirement that student leaders comply with the group’s Statement of Faith and its Sexual Purity Statement. The former requires student leaders of the group to hew to the tenets of traditional Christian theology and the belief that “marriage is exclusively the union of one man and one woman,” while the latter affirms that “the appropriate place for sexual expression is in the context of a marriage relationship.” After a teacher complained about FCA’s faith requirements to the school principal and later presented his concerns to a school leadership “Climate Committee” composed of several school department chairs and administrators, the school revoked FCA’s official recognition as a school student club.

For the 2019-20 school year, FCA applied for recognition again and, predictably, was denied. Yet as the Ninth Circuit notes, the Satanic Temple Club, which even the complaining teacher believed was formed to mock FCA, was approved despite having its own set of non-religious “tenets” similar to FCA’s faith requirements.

Lacking funds to build its spacecraft, the VERITAS project team goes to Iceland

September 26, 2023 12:29 pm Robert Zimmerman

Because NASA has cut almost all funding for the VERITAS mission to Venus in order to fund its overbudget, badly managed, and behind schedule Mars Sample Return mission, the VERITAS science team, held over with only a tiny holding budget for the next seven years, has taken a geology trip to Iceland to study the volcanoes there.

Early last month, one such field campaign took the mission’s science team to a barren and rocky region in Iceland. There, they studied rocks and surfaces near an active volcano named Askja. Such volcanic areas are being used as analogs of Venus to understand the different types of eruptions that may occur on its surface, and to test out various technologies and techniques to prepare for the VERITAS (or Venus Emissivity, Radio Science, InSAR, Topography and Spectroscopy) mission, which is not expected to launch sooner than 2031.

The article at the link focuses on this research, but the real story is this quote:

The VERITAS science team — which is being supported by a shoestring budget of $1.5 million until 2028, after NASA pulled the mission’s funding earlier this year and disbanded its entire engineering wing — collected samples of young rocks and recent lava flows near the Askja volcano that will be analyzed in a lab, according to a NASA statement.

The reason the budget was pulled was to scrap together any funds available from within NASA’s planetary program for that Mars Sample Return Mission, which is doing to the planetary program what the Webb Space Telescope did to NASA’s astronomy program: killing it. As long as NASA and Congress remain committed to that sample return mission, do not expect many new planetary missions to other planets to fly. Its budget has already quadrupled, and its launch is already expected to be delayed. Worse, the mission’s basic design remains tentative, with many major components nothing more than cool graphics on powerpoint presentations, despite having spent gigantic amounts already.

A mountain buried by lava on Mars

September 26, 2023 10:53 am Robert Zimmerman

Click for original image.

Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on July 6, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

This 500-to-600-foot-high hill represents what is likely the top of a much larger mountain, now buried by the flood lava that surrounds it. The edge of that flood lava can be seen best along the base of the hill’s northern slope, where this now hardened lava had washed up against that slope.

That this Martian mountain is very old can be discerned from two features. One, it had to have been there when the lava flowed, and scientists estimate these lava flows are at least one billion years old. Second, peak’s rounded shape and eroded edges (showing terraced layers) suggest it has been here for far longer, allowing Mars’ thin atmosphere and climate to weather it down.

SpaceX donates used Merlin engine and Falcon 9 grid fin to Smithsonian

September 26, 2023 9:10 am Robert Zimmerman

A SpaceX used Merlin engine and a Falcon 9 grid fin will go on display at the Smithsonian Air & Space museum when it reopens its east wing after a major renovation.

In addition to the 2019 launch of SpaceIL’s “Beresheet” moon lander, which entered lunar orbit but crashed into the moon’s surface, the donated Merlin engine was one of nine that flew on the first stages of two other Falcon 9 rockets. In 2018, it was launched twice from Vandenberg Air Force Base (today Space Force Base) in California, helping to loft commercial communications satellites (Iridium-6) and an Argentinian Earth-observation satellite (SAOCOM 1A). The latter stage was the first to land on land on the U.S. West Coast, as opposed to using one of SpaceX’s ocean-going droneships.

The grid fin flew only once, on the 2017 launch that placed a South Korean communications satellite in orbit.

From an engineering perspective, one can’t help wondering why SpaceX chose to donate these items in particular. Why for example did the grid fin fly only once? And why was the Merlin engine retired?

Bob Smith out at Blue Origin

September 25, 2023 8:03 pm Robert Zimmerman

Though this change probably comes four years late, the CEO of Blue Origin, Bob Smith, announced today that he is resigning from the company, effective at the end of the year.

The company’s incredibly slow implementation of all of its projects, which begun when Smith took over in 2017, has made it something of joke punchline in the space business. Suborbital test flights of its New Shepard spacecraft went from almost monthly test flights to none for years. Its orbital New Glenn rocket is four years behind schedule, and it is still doubtful it will fly next year. And the company’s BE-4 rocket engine was also years behind schedule and even now has caused enormous delays for its one outside customer, ULA, delaying the launch of its Vulcan rocket by at least four years. As noted at the link:

Smith brought a traditional aerospace mindset into a company that had hitherto been guided by a new space vision, leading to a high turnover rate. And Blue Origin remains significantly underwater, financially. It is likely that Bezos is still providing about $2 billion a year to support the company’s cash needs.

Crucially, as Blue Origin meandered under Smith’s tenure, SpaceX soared, launching hundreds of rockets and thousands of satellites. Smith, clearly, was not the leader Blue Origin needed to make the company more competitive with SpaceX in launch and other spaceflight activities. It became something of a parlor game in the space industry to guess when Bezos would finally get around to firing Smith.

Smith will be replaced by Dave Limp, who had been Amazon’s VP for devices and services until last month. Whether he can get this company moving again is still an unknown, considering he was also involved in launching Amazon’s Kuiper satellite constellation, the development of which has been as slow and uninspiring as all of Blue Origin’s projects.

Pushback: Pennsylvania HS students stage walk-out protesting rule allowing boys inside girls’ bathrooms

September 25, 2023 1:03 pm Robert Zimmerman

“A little child shall lead them,” painting by James L. Johnson.

Bring a gun to a knife fight: On September 22, 2023 hundreds of students attending high school in Pennsylvania’s Perkiomen Valley School District walked out of classes in protest when the local school board refused to pass a new rule that would forbid boys from using the girls’ bathroom.

The school board had voted against the rule earlier in the week. According to superintendent Dr Barbara Russell it rejected the rule because of its own “anti-discrimination code which states gender identity is a protected class.”

To put it in plain English, the law now allows transvestites or cross-dressing boys to leer at young girls while they go to the bathroom, and no one can do anything about it.

The students in these high schools however did not agree, and made that disagreement quite clear in their protest. I strongly suspect that even when they return to class, there is going to be an organized effort to protect the girls from such perversion. Note this quote:

Almost all of Mars’ geological mysteries in one spot

September 25, 2023 11:26 am Robert Zimmerman

Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on June 30, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). The scientists label it “Mesas in shallow trough,” but that is only describes a small part of what can be seen here, as I interpret it.

The picture itself shows a small portion of the floor of an unnamed 32-mile-wide crater, with the crater’s southeast interior rim beginning its rise in the lower right. First, note the meandering hollow in the upper left, suggesting some past flow. Second, note the pattern of small ridges on the flat crater floor, suggesting some past drying process that left cracks that later filled with material that formed the ridges at a later time. Third, the mesas themselves suggest chaos terrain, often formed on Mars in connection with glacial flows. Fourth, note that the trough which holds the mesas is on the edge of the crater floor, suggesting the trough and mesas mark the erosion that once occurred at the edge of some material, possibly ice, that once filled that floor.

The trough and small meander also signify something far larger that can only be seen when we zoom out.

Strange wormlike tube features on slopes of Martian shield volcano

September 22, 2023 1:20 pm Robert Zimmerman

Click for original image.

Cool image time! The picture to the right, cropped to post here, was taken on June 21, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The scientists label the strange tubelike features that are scattered throughout this picture as “landforms,” which is correctly vague because their origin is utterly inexplicable. The ground here is on the eastern slope of a small 20-mile-wide very flat shield volcano located about 150 miles northwest of the giant volcano Ascraeus Mons. The dark wind streaks point down that grade to the east, away from the shield volcano’s peak about 1,000 feet away. (If you look at the full image this indistinct peak is at dead center, with a linear depression (the volcano’s vent) beginning there and heading to the northeast for about four miles.)

Why these many tubes are all oriented in a northwest-southwest direction, at right angles to the slope, is baffling, especially because they hold to that same orientation all across the shield volcano, no matter the downward direction of the slope.

Pushback: California county sued for using cellphones to track movements of church-goers

September 22, 2023 12:14 pm Robert Zimmerman

Santa Clara seal

They’re coming for you next: Santa Clara county in California is now being sued by Calvary Chapel San Jose and its pastor Mike McClure for using without warrant the GPS data from the cellphones of the church’s members to track their movements without their knowledge.

On August 22, 2023, a lawsuit was filed by Advocates for Faith and Freedom on behalf of Calvary Chapel San Jose against Santa Clara County, California, for utilizing geofencing methods to spy on church members during the COVID-19 pandemic. Earlier this year, Santa Clara County imposed a $1.2 million fine against the church for not abiding by the State’s and County’s COVID-19 restrictions.

Santa Clara County utilized an investigative method known as geofencing. Geofencing is a technological tool the government uses to track people relative to their location and likely locations. This tool is typically used in police investigations of criminal activity and, in these instances, requires a warrant– which is not always granted.

The lawsuit complaint can be read here [pdf]. As it notes:

House speaker Kevin McCarthy proposes bill to extend “learning period” for rocketry

September 22, 2023 9:52 am Robert Zimmerman

The speaker of the House, Kevin McCarthy (R- California) today introduced what he calls the STAR act, which would extend the learning period that exempts the new human commercial space industry from heavy regulation from its impended expiration this year for eight more years, to 2031. From his statement:

The STAR Act would extend the learning period by 8 years to provide sufficient time for the FAA and commercial space industry to develop consensus standards for human safety in space flight. The bill’s proposed 8-year extension corresponds with the lengths of the original learning period — from 2004 to 2012—and the extension by Rep. McCarthy’s SPACE Act (P.L. 114-90) — from 2015 to 2023.

More information here. That McCarthy has introduced this bill suggests its chances of passage are high, assuming a very divided and partisan Congress can manage to pass anything in the coming weeks.
