India’s Aditya-L1 solar telescope initiates some science observations

9:18 am

According to India’s space agency ISRO, its Aditya-L1 solar telescope has begun science observations with one instrument, even as it continues its journey to its final position at L1, one million miles from the Earth.

The activation of STEPS occurred on September 10, 2023, at a distance exceeding 50,000 km from Earth. This distance equates to more than eight times the Earth’s radius, placing it significantly beyond the Earth’s radiation belt region. Following the successful completion of essential health checks for the instrument, the data collection process continued until the spacecraft had travelled beyond the 50,000 km mark from Earth.

All units of STEPS are currently operating within normal parameters. A graphical representation illustrates the measurements, showcasing fluctuations in the energetic particle environment within Earth’s magnetosphere, which were collected by one of the instrument’s units.

It is expected Aditya-L1 will reach L1 in January, where it will begin round-the-clock observations of the Sun, in parallel with NASA’s Soho telescope, which has been at L1 since the 1990s.

Russian investigators pin down cause of Luna-25 failure

10:03 am

Though the investigation is not yet complete, reports out of Russia indicate that the cause of the failure of Luna-25 during an engine burn while in orbit around the Moon has been identified.

The article at the link provides the details, which involve problems with two “BIUS-L accelerometers” during the flight, which for reasons not yet understood were switching from the primary to the secondary randomly during the journey to the Moon, apparently because of some failure.

However, ahead of the fateful lunar orbit correction on August 19, both accelerometers worked correctly, but once the maneuver started, one set failed again, while the flight control system never switched to data from the second set. As a result, onboard computers were not receiving data about critical parameters required for properly completing the orbit correction, such as orientation of the spacecraft in space, velocity and altitude.

If confirmed, this crash scenario would likely implicate deficiencies in the development or testing of the flight control system and its software rather than any mechanical problem of the propulsion system, which was implied in the initial statement about the incident. [emphasis mine]

The highlighted sentence says it all. The serious quality control problems that have hampered Russia’s space efforts remain, and in fact appear systemic throughout its entire aerospace industry. In fact, this failure of a planetary probe helps explain the many difficulties Russia has been having in its war in the Ukraine, attributable to these same issues.

China launches military reconnaissance satellite

9:52 am

China today successfully launched a classified military reconnaissance satellite, using its Long March 2D rocket lifting off from its Xichang spaceport in the south of China.

No word on where the rocket’s lower stages crashed in China. All the stages use hypergolic fuels, which are extremely toxic.

The leaders in the 2023 launch race:

65 SpaceX
43 China
13 Russia
7 Rocket Lab
7 India

American private enterprise still leads China in successful launches 76 to 43, and the entire world combined 76 to 69. SpaceX by itself now trails the rest of the world combined (excluding American companies) 65 to 69.

The first stage completed its fifth flight, landing on a drone ship in the Atlantic.

The leaders in the 2023 launch race:

65 SpaceX
42 China
13 Russia
7 Rocket Lab
7 India

American private enterprise now leads China in successful launches 76 to 42, and the entire world combined 76 to 68. SpaceX by itself now trails the rest of the world combined (excluding American companies) 65 to 68.

Don Rickles, Ruth Buzzi, and Arte Johnson – bloopers from Rowan & Martin’s Laugh-In

6:01 pm

An evening pause: This sequence shows the almost vain attempt to shoot a series of quick jokes using the running gag of Buzzi playing her character “Gladys” on a park bench being “accosted” by Arte Johnson, playing his character “Tyrone”. Rickles adds another element. It shows again that humor is at its heart silliness. If you can’t be silly you can’t be funny, and these three comedians certainly understood that.

Hat tip Cotour.

Virgin Galactic sets Oct 5th launch date for its fifth commercial suborbital flight in ’23

4:47 pm

Virgin Galactic today announced that the launch window for its fifth commercial suborbital flight this year and ninth overall will open on Oct 5th.

The flight will include three private passengers, two Americans and one Pakistani, and a crew of five Virgin Galactic employees.

At this point I don’t consider these suborbital flights to be very newsworthy. However, I decided to highlight this news release because of its stark contrast with Blue Origin. Even before last year’s mishap that grounded Blue Origin’s own suborbital spacecraft, New Shepard, it never flew this frequently. Virgin Galactic took far too long to begin flying (two decades), but it does appear that is now wasting no time trying to catch up.

Blue Origin meanwhile continues to drift along, accomplishing little and appearing to do even less with time.

FAA confirms: No Starship/Superheavy launch license until Interior approves

4:00 pm

The Kafkaesque Interior Department strikcs again!
The Kafkaesque Interior Department
strikcs again!

They’re coming for you next: In an email today, the FAA confirmed what I had reported yesterday, that though it hopes to issue a launch license for the next orbital test flight of SpaceX’s Starship/Superheavy rocket by the end of October, no license will be issued until Fish & Wildlife in the Interior Department agrees.

Before it is authorized to conduct a second Starship/Super Heavy launch, SpaceX must obtain a modified license from the FAA that addresses all safety, environmental, and other regulatory requirements. As part of that license application determination process, the FAA will review new environmental information, including changes related to the launch pad, as well as other proposed vehicle and flight modifications.

The FAA will complete a Written Reevaluation (WR) to the 2022 Programmatic Environmental Assessment (PEA) evaluating the new environmental information, including Endangered Species Act consultation with the U.S. Fish and Wildlife Service. If the FAA determines through the WR process that the contents of the PEA do not remain valid in light of the changes proposed for Flight 2, additional environmental review will be required. Accordingly, the FAA has not authorized SpaceX’s proposed Flight 2. [emphasis mine]

Tragically, my April prediction is coming true. This launch is almost certainly not going to occur before November, and will almost certainly be delayed until next year.

Note again that until the Biden administration, SpaceX was not required to get a detailed environmental reassessement after every Boca Chica test launch. Fish & Wildlife was not involved, as it shouldn’t be. SpaceX made its engineering investigation, the FAA reviewed it quickly, and the company launched again, at a pace of almost one test launch a month, with almost every launch resulting in a crash landing or an explosion.

Under the Biden administration the rules suddenly changed. Now, all launches are environmental concerns, even though we have empirical data for more than seventy years at Cape Canaveral that rocket launches not only do no harm to wildlife, they allow it to thrive because the spaceport creates large zones where nothing can be developed.

In other words, the Biden administration is playing a raw and cruel political game, designed to kill Starship/Superheavy. And it is succeeding, because it will be impossible to develop this rocket on time for its investors and NASA at a pace of only one test launch per year.

Today’s blacklisted American finally wins his four-decade-long fight against the federal government

1:52 pm

So Kafkaesque even Kafka would be astonished
So Kafkaesque even Kafka would be astonished

Bring a gun to a knife fight: In 1982 Sidney Longwell bought a federal oil and gas lease from the Interior Department, with the intention of making money from the oil he extracted from Montana’s Lewis and Clark National Forest. Such leases were not unusual up until then, and in this case was obtained in a perfectly legal manner.

It was not to be, at least for the next four decades, as the Interior Department under five different Presidents repeatedly changed the rules and made arbitary decisions in an effort to somehow illegally cancel that lease. The story, as described by his non-profit law firm, Mountain States Legal Foundation, is quite ugly.

Sidney Longwell first bought his federal oil and gas lease in 1982. But after years of back-and-forth, the Clinton Administration suspended his lease indefinitely in 1993, placing it in regulatory limbo. A decade of fruitless bureaucratic review followed. Finally, in 2013, and with help from Mountain States Legal Foundation, he took the DOI to court, where the agency was forced to address Sidney’s lease. When pressed in 2016 for a decision, the DOI canceled the lease! So, Mountain States and Sidney sued them again.

A triangular Martian hill

A triangular Martian hill
Click for full image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on May 29, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what the science team labels an “unusual shaped hill” that is estimated to be about 20 to 40 feet high.

What makes it unusual? First, it sticks up out of the endless northern lowland plains for no obvious reason, though its shape suggests the existence of bedrock topography that is now buried by the dust and debris that coats the surface of those plains.

Second, the hill itself suggests that it formed after it was covered with debris. Note the crater near its northeast cliff. It appears that the cliff chopped off part of the crater, suggesting that the hill was once level with the surrounding terrain. Some later underground pressure pushed it upward, with its angled sides determined by existing faults.

Why those forces tilted the hill upward as it did, with only its eastern fringes raised, is a question a wide view might answer.

New analysis of Chandrayaan-1’s lunar orbital data might explain its detection of widespread surface hydrogen on the Moon

9:52 am

The Earth's magnetic field, shaped by the solar wind
The Earth’s magnetic field, shaped by the solar wind

One of the significant finds coming from India’s first lunar orbiter, Chandrayaan-1, was the detection of hydrogen in many places across the entire lunar surface, in places where it seemed impossible for hydrogen to be there, even if it was locked in a molecule like water.

Researchers in Hawaii now think they have found an explanation by linking that data to the Earth’s long magnetotail, formed by the solar wind pushing against the Earth’s magnetic field. The graphic to the right illustrates that process. The scientists focused on the kind of weathering processes that occurred both when the Moon was inside that tail, and when it was not.

Li and co-authors analyzed the remote sensing data that were collected by the Moon Mineralogy Mapper instrument onboard India’s Chandrayaan 1 mission between 2008 and 2009. Specifically, they assessed the changes in water formation as the Moon traversed through Earth’s magnetotail, which includes the plasma sheet.

“To my surprise, the remote sensing observations showed that the water formation in Earth’s magnetotail is almost identical to the time when the Moon was outside of the Earth’s magnetotail,” said Li. “This indicates that, in the magnetotail, there may be additional formation processes or new sources of water not directly associated with the implantation of solar wind protons. In particular, radiation by high energy electrons exhibits similar effects as the solar wind protons.”

In other words, the evidence suggests that the hydrogen signal seen by Chandrayaan-1 might have been a very temporary implacement of that hydrogen by the solar wind, which ceases during the Moon’s periodic passages through the magnetotail. The Moon’s harsh environment then causes that hydrogen to vanish, only to reappear when it is once again exposed to the solar wind.

None of this is confirmed, so some skepticism is required. If true, however, it would provide further evidence that the hydrogen signal seen at the lunar poles that scientists hope is evidence of ice in the permanently shadowed craters might be nothing of the sort, and we shall find little ice there.
