SpaceX puts another 22 Starlink satellites into orbit

1:57 pm

SpaceX last night successfully launched another 22 Starlink satellites into orbit, its Falcon 9 rocket lifting off from Cape Canaveral.

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

The leaders in the 2023 launch race:

69 SpaceX
44 China
13 Russia
7 Rocket Lab
7 India

American private enterprise now leads China in successful launches 79 to 44, and the entire world combined 79 to 71. SpaceX by itself now trails the rest of the world combined (excluding American companies), 69 to 71.

Note that this was the 151th successful launch in 2023, all done in the first three quarters, and strongly suggesting the world will complete more than 200 launches this year. This number will top the record of 179 set last year by more than ten percent, and be more than double the number of launches achieved almost every year since Sputnik in 1957.

Hadar Nehemya – Song of Songs

6:01 pm

An evening pause: As Friday night begins the Sabbath in the Jewish faith, this seems appropriate tonight. The group is called 12 Tribes Music. Watch with closed captions turned on to see the King James English translation of these the lyrics, from the Song of Solomon of the Old Testament. The improvised sections of the performance however are wholly modern.

Hat tip Judd Clark.

  • China announces a few basic details of its Chang’e-6 sample return mission

    • All they say is it will launch on a Long March 5 rocket in May 2024, head to the South Pole-Aitken Basin on the far side of the Moon, and operate for 53 days (which likely includes the return of the sample to Earth). Jay spotted one mystery however: The coordinates provided (“S43, W154”) are no where near the south pole, though it is likely in the northernmost part of Aitken Basin.

Updated map of Yutu-2’s travels on far side of the Moon

3:01 pm

Map showing Yutu-2 full route on Moon
Click for original image.

The Chinese agency operating the Yutu-2 rover on the far side of the Moon today released an updated map showing the rover’s full route since landing, the first update since January 2023. That map is to the right, reduced to post here. The landing site is in the lower right, with the rover presently in the upper left.

Since January the rover has apparently traveled only about 300 feet, even though it has had about eight lunar days to travel. Note too that the last update was also the first in three months. It appears the Chinese are either having issues with the rover (not surprising as it has been operating on the Moon for almost five years, since January 2019), or they have decided they don’t need to tell anyone what they are doing.

Since the rover was not expected to last more than a few lunar days (several Earth months), the former is more likely.

Today’s blacklisted American: Coach fired by Vermont school for simply expressing some facts during a civil conversation

2:11 pm

Vermont: Where you are only allowed to say things that support the queer agenda
Vermont: Where the only speech allowed must
support the queer agenda

They’re coming for you next: Despite founding the snowboarding program at Woodstock Union High School in Vermont in 2011 and heading it for its entire history, David Bloch was immediately fired without due process by his school the day after he had a very civil private conversation with his students about males claiming to be female and competing against women.

This is what he did, according to his non-profit legal firm, the Alliance Defending Freedom:

In February [2023], Bloch and his team were waiting in the lodge for a competition to start. That day, Bloch’s team was set to compete against a team that had a male snowboarder who identifies as a female and competes against females. During downtime in the lodge, Bloch overheard a conversation between two of his athletes about that male competing against females. Bloch joined the conversation to comment that people express themselves differently and that there can be masculine women and feminine men. He also affirmed that as a matter of biology, males and females have different DNA, which causes males to develop differently from females and have different physical characteristics, and that those biological differences give males an advantage in athletic competitions.

The conversation was respectful among all parties and lasted no more than three minutes. It took place entirely outside the presence of the male snowboarder who identifies as female, and Bloch’s team and the other team went on to compete without incident. After the competition, the two teams and their coaches, including Bloch, shared a bus home.

The very next day the superintendent of the Windsor Central Supervisory Union, Sherry Sousa, called Bloch into her office to tell him he was fired, even though the investigation against him was incomplete.

Is this the source of the sand for the giant dune sea that surrounds the Martian North Pole?

12:49 pm

Overview map

Circling the north pole of Mars is a gigantic dune field dubbed Olympia Undae, with its densest regions (marked in red on the overview map to the right) estimated to be 700 miles long and covering 120 degrees of longitude.

Where does all the sand come from that created this dune ocean? We now have a rough idea. The arrows on the map to the right indicate the direction of the prevailing winds, as recently determined by scientists studying the orientation of dunes. From this it appears that much of the dust comes from the north polar icecap itself, from its lower layers where dust and ice are cemented together. The prevailing winds, especially in the canyons that cut into the icecap, drive that dust out from the lower layers, where it over eons has piled up in that circular ocean of sand.

The white cross marks the location of today’s cool image, an attempt by scientists to photograph at high resolution one of the sources of this sand, on the edge of the icecap.

Hubble data shows expansion of supernova remnant

9:57 am

Cygnus loop filament

Astronomers have created a four-second long movie using Hubble images collected over twenty years that shows the expansion of one filament in the Cygnus Loop supernova remnant, the explosion of which is thought to have occurred 20,000 years ago.

The picture above is one frame of that movie. The filament is estimated to be two light years in length.

By analyzing the shock’s location, astronomers found that the shock hasn’t slowed down at all in the last 20 years, and is speeding into interstellar space at over half a million miles per hour – fast enough to travel from Earth to the Moon in less than half an hour. While this seems incredibly fast, it’s actually on the slow end for the speed of a supernova shock wave.

Two versions of the movie are at the link, with the longer providing excellent context.

Parker completes 17th close fly-by of the Sun, setting new records

9:43 am

The Parker Solar Probe on September 27, 2023 completed its seventeenth close fly-by of the Sun, setting new speed and distance records.

Set up by a gravity-assist flyby of Venus on Aug. 21, the close approach (known as perihelion) occurred at 7:28 p.m. EDT, with Parker Solar Probe moving 394,736 miles per hour (635,266 kilometers per hour) around the Sun – another record. The milestone also marked the midway point in the mission’s 17th solar encounter, which began Sept. 22 and continues through Oct. 3.

It zipped past the Sun at a distance of only 4.51 million miles, also a record.

Whether it survived this fly-by will not be confirmed until October 1, when it is able to safely send its first data back after moving far enough away from the Sun to reopen communications.

Orbital Reef partnership between Blue Origin and Sierra Space in trouble

9:36 am

According to anonymous sources, CNBC reports that the partnership between Blue Origin and Sierra Space to build the private commerical Orbital Reef space station is possibly breaking up.

The companies announced Orbital Reef as a co-led project in 2021, but updates about the project dried up in the past year. The pair of private space companies are now navigating a potential end to the Orbital Reef partnership, according to three people who spoke to CNBC about the situation.

Those people, speaking on the condition of anonymity to discuss nonpublic matters, emphasized that discussions are ongoing and described the situation as fluid. But other development projects with more significant current contracts – such as Blue Origin’s Blue Moon lunar lander and Sierra Space’s Dream Chaser spaceplane – have taken higher priority for both companies, those people said.

To readers of Behind the Black, this possible break-up is not a surprise. In June Sierra’s announcement of its own independent space station based on its LIFE modules suggested it had its own doubts about Orbital Reef. Then in August, when Sierra announced a partnership with Redwire to launch LIFE as an independent station, I wrote this:

What struck me about this deal is the shrinking mention of Blue Origin. Originally that company was listed as one of the major players in building this private space station, dubbed Orbital Reef, in which LIFE is only the first module. In the past year however its participation seems less and less significant in every subsequent press release. It appears to still be part of the project, but it is Sierra Space that is leading the effort, and appears to be making things happen.

But then, the track record of Blue Origin is to not make things happen. It could very well be that events are once again overtaking it. Sierra Space can’t wait for Blue Origin to slowly get its act together. It is finding ways to get things done, even if that means Blue Origin gets left behind.

Today’s CNBC story reinforces this conclusion. So does its timing with the removal of Blue Origin’s CEO, Bob Smith, earlier this week. It could be that the failure of Blue Origin in the Orbital Reef partnership was the final straw for Jeff Bezos.

The problem for NASA in this is that the agency awarded a $130 million contract to the Orbital Reef partnership, with Blue Origin listed as the lead contractor which controls the contract. If that partnership ends, that contract must get renegotiated or cancelled, or gets transferred from Blue Origin to Sierra Space (the most likely outcome).

Ispace wins $55 million NASA contract for lunar landing mission

9:17 am

The Japanese company Ispace, which is also establishing operations in the U.S., has won a $55 million NASA contract to send a lunar landing plus communications relay satellites to the Moon in 2026.

Ispace’s Hakuto-R1 lander attempted a landing on the Moon in April, but crashed. The company has a second Hakuto-R mission presently targeting launch next year. The NASA contract would the company’s third, which will be built in its new U.S. facility and be called Apex-1.

In today’s briefing, Ispace representatives announced that the primary customer for its upcoming Mission 3 is NASA, which has selected the company as part of its Commercial Lunar Payload Services program (CLPS). Ispace stated during the briefing that it has signed a $55 million contract with NASA for Mission 3 in order to land near the lunar south pole carrying approximately 210 pounds (95 kg) of scientific payloads.

But that’s not all the mission will do. On its way to the lunar surface, Mission 3 will deliver relay satellites that will remain in orbit around the moon to serve as communication relays.

Though it will not be surprising if these launch dates slip, Ispace is in a strong position to succeed, considering it is presently the only private company to launch a Moon lander, and got very close to putting it down on the lunar surface successfully.
