NASA’ safety panel illustrates the impossibility of exploration by NASA
Last week NASA’s Aerospace Safety Advisory Panel (ASAP) issued its 2017 report [pdf], detailing the areas it has concerns for human safety in all of NASA’s programs. Not surprisingly, the report raised big issues about SpaceX, suggesting its manned launch schedule was questionable and that there were great risks using the Falcon 9 rocket as presently designed.
ASAP was especially concerned with the issues with the Falcon 9 COPV helium tanks and how they were connected with the September 2016 launchpad explosion, as well as SpaceX’s approach to fueling the rocket. Below is a screen capture of the report’s pertinent section on this.
The report complements NASA and SpaceX for looking at a new design for the COPV helium tanks, but also appears quite willing to force endless delays in order to make sure the issue here is completely understood, even though this is likely impossible for years more.
ASAP also raises once again its reservations about SpaceX’s method of fueling the Falcon 9, which would have them fill the tanks after the astronauts are on board so that the fuel can be kept cold and dense to maximize performance. This issue I find very silly. The present accepted approach is to fill the tanks, then board the astronauts. SpaceX wants to board the astronauts, then fill the tanks. Either way, the astronauts will be in a rocket with tons of volatile fuel and oxidizer. I really do not see why it makes that much of a difference, especially with SpaceX building a successful track record using its approach with each successful commercial launch. They did 18 last year alone.
Below the fold is a screen capture of the report’s entire summary, with some sections highlighted by me.

1 in 10 graduates of DC schools rarely if ever attended school
The coming dark age: An investigation into the Washington DC school system has found a great deal of corruption in grading, including the fact that 1 in 10 graduates receive diplomas even though they rarely if ever attend school.
The report, commissioned by the Office of the State Superintendent of Education, portrays a school system riddled by student absenteeism and teachers who feel pressured to push chronically absent high school seniors across the graduation stage regardless of whether they earned their diplomas.
The review saved some of its sharpest criticism for Ballou High School, which has been engulfed in controversy amid a graduation scandal. The report found that the school’s administrators told teachers that a high percentage of their students were expected to pass and encouraged them to provide makeup work and extra credit to students, no matter how much school they missed. Teachers received little training in a new grading system, and their annual performance reviews hinged in small part on their success in graduating students.
At the same time the report was released, D.C. Public Schools Chancellor Antwan Wilson announced that Ballou Principal Yetunde Reeves, who had been reassigned pending the investigation, will not return to the Southeast Washington school.
While this kind of corruption in public schools is somewhat rampant throughout the country, it has tended to happen far more in cities and states that have been controlled for years by a one-party political machine, which in the U.S. has almost routinely been a Democratic Party machine. The problem isn’t specifically Democrats (though that party’s policies almost routinely make things worse). The problem is the one-party political machine and a reliance on a big government school system.
It would be far better to eliminate the whole public school system, including the taxes it confiscates, and leave it to the families in a local neighborhood to simply band together, hire a teacher, and start a one-room school house for their elementary school kids. These small schools could then band together to form a larger high school, all paid for directly by the parents.
Sounds absurd? It was how the colonies and the U.S. did it for their first few hundred years, until the late 1800s.
I admit that going back to the old way might not work, however. There has also been a dumbing-down of standards nationwide, by everyone. We also no longer have the moral and religious framework that dominated American culture before the mid-20th century that required all parents to get their kids educated.
Virgin Orbit gets another smallsat launch contract
Capitalism in space: Virgin Orbit has signed another launch contract, this time to launch nanosats for a company that provides services to the airline industry.
The flight, which is bound for a low-inclination orbit, is scheduled to occur in early 2019. GomSpace will use the launch to further build out a constellation of small satellites that will use Automatic Dependent Surveillance-Broadcast (ADS-B) and Automatic Identification System (AIS) signal monitoring to track civilian aircraft and ocean-going vessels. This satellite constellation will provide continuous monitoring between 37 degrees North and 37 degrees South, helping provide global situational awareness for air-traffic controllers and shipping companies, and aiding in the identification and location of wayward or missing planes and ships.
The satellites slated for flight on LauncherOne are based closely on the flight-proven hardware used in the successful GOMX-1 and GOMX-3 missions, and will be designed, manufactured, and commissioned by GomSpace. The constellation will be operated by GomSpace’s Mauritius-based customer, Aerial & Maritime Ltd., once in orbit.
This appears to be the fifth launch contract that Virgin Orbit has signed, all with different companies. The recent stories have all suggested commercial launches will begin in 2019. I wonder, considering the company has yet to test fly LauncherOne, its rocket, even once.
There could be many reasons the company is getting so many contracts at this time. They could be offering great deals, with no commitment. They could be farther along in testing than the public knows. They could be fooling the satellite companies (though I doubt this because of the number of companies now signed on). Their other partners, some quite large and powerful, might be exercising clout to get these small smallsat companies to announce a launch contract in order to improve Virgin Orbit’s footprint in the market.
Regardless, we shall find out soon. To start commercial operations by early 2019 they must do some initial flight tests of LauncherOne this year. Time is running out for them to meet this schedule.
Criminal charges filed by Navy against commanders of collision ships
The Navy today announced that it is filing criminal charges against the commanding officers of the two ships that were involved in collisions earlier this year.
The commanders of the two guided-missile destroyers that were involved in fatal collisions with merchant ships in 2017 will face military criminal charges that include charges of dereliction of duty, hazarding a vessel and negligent homicide, after the two incidents that resulted in the death of 17 sailors total, USNI News has learned.
Cmdr. Bryce Benson, former commander of USS Fitzgerald (DDG-62), along with three Fitzgerald junior officers, face a mix charges that include dereliction of duty, hazarding a vessel and negligent homicide related to the June 18 collision between the ship and ACX Crystal that resulted in the death of seven sailors, according to a statement from the U.S. Navy provided to USNI News.
Cmdr. Alfredo J. Sanchez, former commander of USS John S. McCain (DDG-56), faces similar dereliction of duty, hazarding a vessel and negligent homicide charges for the Aug. 21 collision between the guided-missile destroyer and a chemical tanker off the coast of Singapore that resulted in the death of 10 sailors.
I don’t know whether the military trials will be public (they should be), but if so they will reveal some very interesting details about what was happening on these Navy ships that allowed these collisions to occur.
Falcon Heavy static fire test delayed again
It appears that the first static fire test of the Falcon Heavy has been delayed again from today to later in the week.
There is no word on why the delay, but all indications suggest that they are going through the process step-by-step with great care. As they find things that need addressing they are addressing them, and that only when all issues are resolved will they go forward.
Detailed update on Falcon Heavy static fire test set for later today
Link here. The article has a lot of good information not only about the test but about the launchpad and how it will be used in the future.
One take-away that I came off with however came from the picture of the Falcon Heavy on the launchpad. It made me realize how far apart the two side stages sit from the core stages, as the rocket is now reconfigured. My impression of most strap-ons today is that they are placed very close to the core, and they generally have aerodynamic cones that slope away from the core, so that the air is directed away from the space between the stages. Falcon Heavy however has all that space, and the side strap-ons have rounded cones.
I wonder if this is one of the rocket’s most worrisome unknowns, as it travels through Max Q, the period shortly after launch when the stresses created from its speed and the atmosphere are the highest. As designed, a lot of atmosphere will travel between the stages. While this isn’t entirely unique (the shuttle had a somewhat comparable gaps between its various parts), I do wonder.
On the way home
Diane and I are about to board the airplane here in the Bahamas to return to the U.S. Twas an interesting and pleasant weekend.
Not surprisingly, the TSA were pigs as we left. It turns out that it is forbidden to carry from foreign countries a ham sandwich on the plane to eat. Either that, or they like to steal sandwiches from passengers for their own lunch.
As I said to the TSA agent, “Pigs. This is not the country I was born into.” She then tried to debate politics with me and I said, “No, please, let’s not.”
The real evil here is that the agent was upset that I was honest about having the sandwich. If I had lied and said we had no food with us, they wouldn’t have checked and all would have been fine. The whole setup was designed to make everyone dishonest and liars. If you were honest, you were punished.
VSS Unity completes 7th glide test
Capitalism in space: Virgin Galactic’s Unity suborbital spaceship completed 7th glide test today.
I must admit that I am only reporting this because I feel obligated to. This was their first flight in five months, and they have still not done a powered flight. I cannot get excited about Virgin Galactic and SpaceshipTwo until I actually see them reach space, something they have still not accomplished after fourteen years of development.
Rocket Lab announces January launch window
Capitalism in space: Rocket Lab has announced that it will attempt the second test launch of its Electron rocket during a nine day launch window beginning on January 20.
Bad weather and technical issues prevented this launch in December. Meanwhile, Japan is also planning a test launch in January of its only smallsat rocket, the SS-520. The Japanese entry is a demo mission designed and built by that country’s space agency, while Rocket Lab is entirely private. Both however provide more evidence that 2018 will be a booming year (no pun intended) for rockets.
SpaceX pushes back its manned flights
The first launch dates for SpaceX’s manned Dragon capsule have apparently been rescheduled, with the new dates August 2018 for the first unmanned demo flight and December 2018 for the first manned flight.
This is a four month delay from the previous announced dates of April and August.

Russia to launch a dozen cubesats for Planet
Capitalism in space: Planet has signed a deal with the Russian government entity that bundles smallsat secondary payloads to launch a dozen cubesats on a Soyuz rocket presently scheduled to launch later this year.
This agreement provides further evidence that the cubesat commercial industry is here to stay. There are a lot of these contracts right now (India is scheduled to launch 30 tomorrow). The need for more small rockets to launch such satellites appears almost overwhelming, and thus a good financial choice.
