SpaceX’s Falcon 9 launches 21 second generation Starlink satellites

SpaceX today successfully launched 21 second generation Starlink satellites, dubbed V2-minis because they are smaller than the full version that will be launched on Starship.

The Falcon 9 rocket used a first stage flying on its third flight. It successfully landed on a drone ship in the Atlantic. The fairings were completing their second flight.

The 2023 launch race:

13 SpaceX
7 China
3 Russia
1 Rocket Lab
1 Japan
1 India

American private enterprise now leads China 14 to 7 in the national rankings, and the entire world combined 14 to 12. SpaceX alone leads the entire world combined 13 to 12.

The shift away from government schools, at all levels, accelerates

Parents are rejecting this in droves
Parents are rejecting this mantra in droves

It has been clear for decades that the public schools in most major urban areas — all of which have been run by Democrats — have been failing badly at their primary task of educating children. Two recent stories underlined this failure.

First, in Baltimore a study found that not one student in twenty-three of the city’s schools was proficient in math.

Through an analysis of 150 Baltimore City Schools, 23 of them, including 10 high schools, eight elementary schools, three high schools and two middle schools, no students met math grade-level expectations, according to a report by Project Baltimore. Approximately 2,000 students took the state administered math exams that tested proficiency levels.

…An additional 20 schools in the district had no more than two students proficient in math, Project Baltimore reported. Another three schools in the district, which are for incarcerated students and students with disabilities, had no students that met grade-level expectations.

Essentially, just under one third of all of Baltimore’s public schools failed to teach any of their students math. Period. For any school system to accept this level of failure is beyond disgusting. Everyone who works for Baltimore’s schools should be canned, now.

Then, just days later, another story revealed that fifty-five of Chicago’s public schools were also totally incompetent at teaching math or reading, and should find other work.

Drilling success for Curiosity in the marker layer?

The fifth drill hole in the marker band
Click for original image.

It appears from the most recent image sent back from Curiosity today of its February 25, 2023 attempt to drill into the marker layer on Mount Sharp — the fifth such attempt — the rover finally succeeded in getting deep enough to collect sufficient sample material for analysis.

That image is to the right, cropped, reduced, and sharpened to post here. Note that it is not yet confirmed from the science team that this drill attempt was deep enough. What makes this particular drilling attempt intriguing is how the many thin layers of the marker layer responded to the stress of the drill. The top layer cracked like a plate and separated from the adjacent lower layer during drilling. It apparently was hard enough to retain most of its structure, and rather than crumble the drill stresses caused a large section to break away and lift off.

The panorama above, cropped and reduced to post here, was taken the same day from this location, produced from 37 photos taken by the rover’s right navigation camera. The cropped section above looks forward at what I previously labeled “a Martian hill of pillows.” The overview map below shows the context of this panorama.

Galaxies afloat in space

Galaxies afloat in space
Click for original image.

Cool image time! The picture to the right, cropped and reduced to post here, was taken by the Hubble Space Telescope and released today. It is part of a survey project studying what the press release calls “jellyfish galaxies,” spiral galaxies that have long extended arms.

As jellyfish galaxies move through intergalactic space they are slowly stripped of gas, which trails behind the galaxy in tendrils illuminated by clumps of star formation. These blue tendrils are visible drifting below the core of this galaxy, and give it its jellyfish-like appearance. This particular jellyfish galaxy โ€” known as JO201 โ€” lies in the constellation Cetus, which is named after a sea monster from ancient Greek mythology. This sea-monster-themed constellation adds to the nautical theme of this image.

On the lower left is what the press release calls an elliptical galaxy, probably because it has no obvious arms. It is however shaped more like a spiral galaxy, since ellipticals tend to be spherical. If you look close you will also notice at least five-plus other galaxies in this picture, all smaller either because they are much farther away or are simply much smaller.

New company aims at providing floating ocean-going spaceports for rocket companies

A new startup, The Spaceport Company, is building a floating ocean-going spaceport for smallsat rocket companies, with the company’s long term goal to provide a range of floating spaceports for rockets of all sizes.

The Spaceport Company is planning to demonstrate a sea-based launch platform in May, conducting four sounding rocket launches from a modified ship in the Gulf of Mexico. โ€œThat will help us prove out our logistical, operational and regulatory procedures,โ€ said Tom Marotta, founder and chief executive of the company, during a panel at the SpaceCom conference Feb. 23.

Those tests will be a precursor to developing a full-scale sea-based platform, based on a ship design called a liftboat. That ship can sail to a location and lower legs to anchor itself on the seafloor. The boat can then lift itself out of the water and serve [as] a launch platform.

That first orbital platform would provide launch services for smallsat rockets capable of launching up to one ton, and if the company’s suborbital test launches go well and further investment capital arrives, could be operational by 2025.

Astroscale raises $76 million in private investment capital from Mitsubishi, space tourist Maezawa, and others

The Japanese startup Astroscale, which is focused on removing orbital space junk and robotic satellite repair, has raised $76 million in private investment capital, bringing the total it has raised from private sources to $376 million.

Astroscale Holdings Inc. (“Astroscale”), the market leader in satellite servicing and long-term sustainability across all orbits, has closed a Series G round with more than U.S. $76 million in funding from new investors Mitsubishi Electric, Yusaku Maezawa, Mitsubishi UFJ Bank, Mitsubishi Corporation, Development Bank of Japan, and FEL Corporation.

The investors are of interest. Billionaire Maezawa, who has already flown to ISS as a tourist and has purchased a lunar mission on SpaceX’s Starship, contributed $23 million of the $76 million. Mitsubishi in turn has contributed at least $25 million. Both suggest Astroscale is now on very solid financial ground.

It also appears that the big players in Japan see Astroscale’s business plan as viable and expected to be profitable.

Manned Endeavour launch tonight on Falcon 9 scrubbed at T-2:12

UPDATE: New launch date, still tentative pending investigation into the technical issue that forced tonight’s scrub, is now March 2, 2023, at 12:32 am Eastern.

The fourth manned launch of SpaceX’s Endeavour Dragon capsule, carrying four astronauts, was scrubbed tonight at T-2:12 because of an issue with ground ignition system of the rocket. As of posting no additional details had been released, as the launch team was in the process of standing down, unloading the fuel from the rocket in preparation for getting the astronauts out of the capsule safely.

Assuming the issue can be fixed quickly, there is another launch opportunity tomorrow, February 28, at 1:22 am (Eastern). For SpaceX a launch scrub for technical reasons has become remarkably rare. In fact, the only other scrub since 2020 for technical reasons took place in July 2022. During that time the company successfully launched more than 100 times, thus getting off the ground as scheduled about 99% of the time, excluding weather delays.

While the Endeavour capsule will be making its fourth flight, when this launch finally takes place the rocket’s first stage is a new stage and will be making its first flight. This has also become a relatively rare event for SpaceX. In 2022, of the company’s 61 launches, only three used new first stages. So far this year this launch will be the second new stage to fly, out of the thirteen launches so far.

IBEX in safe mode

On February 18, 2023, NASA’s Interstellar Boundary Explorer (IBEX) went into what the engineers have dubbed “contingency mode”, which seems to be a variation of safe mode, due to a computer issue that is preventing the spacecraft from accepting commands.

While fight [sic] computer resets have happened before, this time the team lost the ability to command the spacecraft during the subsequent reset recovery. The team also was unsuccessful in regaining command capability by resetting ground systems hardware and software.

Flight software still is running, and the spacecraft systems appear to be functional. However, while uplink signals are reaching the spacecraft, commands are not processing. If the mission teamโ€™s efforts to find and remedy the loss of command capability remain unsuccessful, IBEX will perform an autonomous reset and power cycle on March 4.

IBEX was designed to study the boundary between the interstellar space and the solar system, and do it somehow from Earth orbit.

Where to get legal help if you have been illegally blacklisted

Today’s blacklist column is a follow-up of an earlier column from August 2022, when I provided a detailed list of the various legal non-profit firms that now take on cases to defend the blacklisted. The number of such firms has grown, and I decided it was time to provide a new more complete list.

These non-profit law firms are all dedicated to fighting the leftโ€™s shameless effort to illegally and immorally blacklist, blackball, censor, and destroy its opposition, and have been increasingly successfully in winning their cases. The list, though obviously not all inclusive, describes what appear to be the most active and successful non-profit law firms presently winning first amendment cases nationwide. (Note too that the ACLU is not on the list, as that organization a long time ago abandoned its foundational goal of protecting free speech and has instead become an agent acting to increase the left’s power over ordinary citizens.)

In choosing among these law firms, make sure you review their entire website and the many cases they are handling. Some firms might be less appropriate for your situation, and it is necessary on your part to do the due diligence to figure this out.
