FCC raises questions about SpaceX’s application to link cell phones to Starlink

9:20 am

The FCC has responded to SpaceX’s application to link cell phones to Starlink with a set of questions, mostly centered on finding out whether the company’s system might interfere with other communications systems.

“This analysis should take into account the worst case scenario of all satellites transmitting at the same time, including different power levels required for rain fade and cloud cover as well as clear sky conditions over a particular area of coverage,” the FCC wrote.

In addition, the same analysis should look at the “possibility of loss of service by other authorized satellite and terrestrial operators in that area,” the Commission added. Another request asks SpaceX to provide “a map with projected beam coverage” for the US, showing the maximum and typical power levels of the satellite cellular service. The FCC also wants to know how the company can shut down the cellular Starlink system in the event interference arises over certain geographic areas.

The FCC’s concerns appear reasonable, but no one should dismiss the possibility that politics are involved as well. The Biden administration, which now has a majority of appointees on the FCC, has made it clear it opposes almost everything Elon Musk is doing.

Virgin Galactic trims staff and spending

9:08 am

Despite having completed its fifth commercial suborbital flight on November 2, 2023, Virgin Galactic announced yesterday that it is laying off staff and cutting spending.

The number of people laid off was not revealed. Supposedly the company has done this as part of its effort to develop an upgraded version of SpaceShipTwo.

The company reported having $980 million of cash and equivalents on hand at the end of the second quarter this year, when it reported a net loss of $134.4 million. The company has not disclosed its estimated costs for development of the Delta vehicles, but said it expected those vehicles to enter service in 2026. The company expects only limited revenue from VSS Unity, which is able to fly monthly carrying up to four customers at a time.

I instead suspect that demand for suborbital flights is dwindling because of the competition from orbital operations. Had this company started flying a decade ago, as promised numerous times by Richard Branson, it would have been ahead of the curve. It didn’t and thus missed the boat.

Bulgaria to sign Artemis Accords

9:01 am

NASA yesterday announced that Bulgaria will sign the Artemis Accords tomorrow, becoming the 32nd nation to join the alliance.

The full list of signatories is as follows: Argentina, Australia, Bahrain, Brazil, Bulgaria, Canada, Columbia, Czech Republic, Ecuador, France, Germany, India, Iceland, Israel, Italy, Japan, Luxembourg, Mexico, the Netherlands, New Zealand, Nigeria, Poland, Romania, Rwanda, Saudi Arabia, Singapore, South Korea, Spain, the United Kingdom, the United Arab Emirates, the Ukraine, and the United States.

The competing alliance of communist nations, led by China, includes only Russia, Venezuala, Pakistan, Belarus, Azerbaijan, and South Africa. That former deep Soviet block nations like Bulgaria and Romania went with the west rather than China illustrates the international distrust of China and its authoritarian methods.

Regardless, we now see a rough outline of the coming cold war in space.

Lucy: Dinkinesh’s moon is actually a contact binary

8:42 am

Dinkinesh's contact binary moon
Click for original image.

As more images have arrived from Lucy’s fly-by of Dinkinesh scientists have discovered that its moon is actually a contact binary.

The Lucy picture to the right, cropped, reduced and sharpened to post here, shows that contact binary on the right.

This image shows the asteroid Dinkinesh and its satellite as seen by the Lucy Long-Range Reconnaissance Imager (L’LORRI) as NASA’s Lucy Spacecraft departed the system. This image was taken at 1 p.m. EDT Nov. 1, 2023, about 6 minutes after closest approach, from a range of approximately 1,010 miles. From this perspective, the satellite is revealed to be a contact binary, the first time a contact binary has been seen orbiting another asteroid.

Data from the fly-by is still being downloaded.

SpaceX launches 23 Starlink satellites

8:27 am

SpaceX last night successfully launched 23 Starlink satellites, its Falcon 9 rocket lifting off from Cape Canaveral.

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

The leaders in the 2023 launch race:

80 SpaceX
50 China
14 Russia
7 Rocket Lab
7 India

American private enterprise now leads China 92 to 50 in successful launches, and the entire world combined 92 to 79. SpaceX by itself once again leads the rest of the world (excluding American companies) 80 to 79.

While 100 universities condemn Hamas, the Ivy League is condemned for looking the other way

1:33 pm

These might be the worst colleges in the country
These are probably the worst colleges in the country

The one good thing that has come from the horrible slaughter of innocents by Hamas on October 7th is that it has made obvious the bankruptcy of America’s so-called elite Ivy League colleges, suggesting without question that if you are either a high school student who wants to get a real education or an employer who wants to hire the best college graduates, these are not the places to find either.

The constrast was made very clear by two letters this week. First, more than one hundred universities nationwide issued a letter harshly condemning Hamas while expressing whole-hearted support for Israel.

We Stand Together With Israel Against Hamas

We are horrified and sickened by the brutality and inhumanity of Hamas. Murdering innocent civilians including babies and children, raping women and taking the elderly as hostages are not the actions of political disagreement but the actions of hate and terrorism. The basis of all universities is a pursuit of truth, and it is times like these that require moral clarity. Like the fight against ISIS, the fight against Hamas is a fight against evil. We, the presidents and chancellors of universities, colleges and higher education associations across the United States of America and the world, stand with Israel, with the Palestinians who suffer under Hamas’ cruel rule in Gaza and with all people of moral conscience. [emphasis in original]

Not surprisingly, none of the Ivy League schools as well as Stanford and the entire California university system signed on. Apparently the torture, rape, and murder of women and children is okay with these “elite” colleges, as long as it is Jewish women and children who are tortured, raped, and murdered.

The second letter directly addressed this lack of moral commitment by these so-called “elite” colleges, and did so by attacking Harvard in particular. On November 4, Bill Ackman, a billionaire hedge fund manager and Harvard alumni, published a 3,000+ word letter directed Harvard’s president, Claudine Gay, and the Harvard Corporation Board, strongly condemning Gay’s unwillingness to unequivocally condemn the oppressive culture on Harvard’s campus, as well as its growing anti-Semitism.

The grand Valles Marineris of Mars

11:30 am

The grand canyon of Mars
Click for original image.

Time for another cool image of the grand canyon of Mars, Valles Marineris. The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on May 24, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows a small section of the floor of this gigantic canyon, where orbital data has detected light-toned materials. From the caption:

Many of the Valles Marineris canyons, called chasmata, have kilometer-high, light-toned layered mounds made up of sulfate materials. Ius Chasma, near the western end of Valles Marineris, is an exception.

The light-toned deposits here are thinner and occur along both the floor and walls, as we see in this HiRISE image. Additionally, the sulfates are mixed with other minerals like clays and hydrated silica. Scientists are trying to use the combination of mineralogy, morphology, and stratigraphy to understand how the deposits formed in Ius Chasma and why they differ from those found elsewhere in Valles Marineris.

The picture however gives no sense of the monumental terrain that surrounds it.

ESA commits to a zero space junk policy

9:18 am

The European Space Agency (ESA) announced yesterday that it is now commited to a zero space junk policy, and has established its own standards for the end-of-life disposal of all orbiting spacecraft, to be included during the design and construction.

The policy also requires collision avoidance systems as well as engineering designed to reduce light pollution that harms ground-based astronomy.

Three European nations sign deal with Arianegroup for use of Ariane-6

9:12 am

In a separate deal outside of the European Space Agency, Germany, France, and Italy have signed a deal with the private rocket company Arianegroup to use its still unlaunched Ariane-6, assuming the company can reduce costs.

The agreement will provide €340 million ($365 million) of financing a year for Arianespace’s Ariane 6 rocket in exchange for a commitment to an 11% cut in costs. The rocket will also be awarded at least four missions from public institutions a year, while the lighter Vega C launcher will get at least three.

Essentially the deal is intended to keep Ariane-6 afloat, as its high cost has made it difficult to attract customers. At the same time, the contract demands those costs be reduced, and adds pressure to that demand by noting that future and additional launches will be awarded on a purely competitive bidding process. It appears these three countries will open bidding not only to the new rocket startups being developed in Europe, but American rocket companies as well.

Japan delays asteroid mission due to its rocket problems

9:02 am

Japan’s space agency JAXA has decided to delay its Destiny+ mission to the asteroid Phaethon until 2025 due to the continuing problems getting its Epsilon-S rocket off the ground.

Epsilon-S is intended as an upgrade to Japan’s Epsilon rocket, but its development has been plagued by failures. In October ’22 there was a launch failure of Epsilon, and in July ’23 the second-stage solid-fueled motor of Epsilon-S exploded during a test.

Phaethon is the parent asteroid of the Geminid meteor shower that occurs each year in December. According to the original plan Destiny+ would have done its fly-by of the asteroid in 2029. No new arrival date has been announced.
