The trials and tribulations of Blue Origin’s BE-4 engine

Link here. The article tries to provide some explanations for the delays at Blue Origin that have put the BE-4 engine years behind schedule.

The first and most important fact gleaned from the article is that flightworthy versions of this engine will not be ready this summer as promised, and will likely not get delivered to ULA for its Vulcan rocket before the end of the year, causing its inaugural launch to be delayed to the second half of ’22. This also means that Blue Origin’s own orbital rocket, New Glenn, will likely not launch until late next year, at the earliest.

Moreover, the engines that Blue Origin will deliver to ULA will not be fully tested, and might require replacement if tests on other engines reveal more problems.

The article’s most important revelation about the delays however is this:

One of the most persistent problems, sources said, is that the BE-4 engine testing and development program has been relatively “hardware poor” in recent years. Effectively, this means that the factory in Washington has not had enough components to build development engines, and this has led to extended periods during which no testing has occurred on the stands in Texas.

It was surprising to hear this because back in the spring of 2017 Blue Origin stated publicly that its development program was hardware rich. After arriving as CEO in late 2017, however, [Bob] Smith appears to have focused more on a substantial reorganization of Blue Origin’s leadership rather than hardware development. Other programs were prioritized, too, so the BE-4 team did not get all the resources and freedom it needed to proceed at full throttle. [emphasis mine]

To put it more bluntly, Smith decided it was more important to rearrange the deck chairs rather than launch lifeboats into the water. As a result, Blue Origin has essentially wasted the last four-plus years.

There are signs that the company has changed course away from Smith’s focus, but we shall have to wait and see. The childish press release issued by Blue Origin yesterday, claiming its manned lunar lander was far better than SpaceX’s Starship and should have been chosen by NASA, suggests that the course change has not been as thorough as one would hope. The amount of intellectual dishonesty contained in that release is somewhat disturbing, especially coming from a rocket company:

Blue Origin appears to be, at minimum, cherry picking its comparisons. The graphic notes that the Starship-Super Heavy system hasn’t launched yet. Starship has launched six miles into the air on several occasions, but not with its Super Heavy booster. It also points out that SpaceX’s Starship facilities in Boca Chica, Texas have never accommodated an orbital launch. Blue Origin, though has never launched any rocket to orbit from anywhere.

The graphic doesn’t, however, note the cost of the Starship lunar lander. SpaceX’s proposal estimates that it will cost NASA $2.9 billion, while Blue Origin’s gave a price of $5.9 billion. [emphasis mine]

For the management of a rocket company to not recognize the fundamental facts indicated by the highlighted words above, or to make believe they are unimportant, does not bode well for that rocket company. Rather than focusing on getting its rocket finally off the ground, the management appears instead unwilling to face some hard facts, and fix them.

Meanwhile, SpaceX keeps barrelling along, focused not on petty managment issues or whiny complaints, but on actually building rockets that fly.

Zhurong travels another 700 feet on Mars

Zhurong's location

According to a new update from China’s state-run press today, since the last update of its Zhurong Mars rover on July 31st, the rover has traveled just over 700 feet, for a total travel distance of about 2,624 feet, just under a half mile.

As of August 6, 2021, the rover has worked on the surface of Mars for 82 Martian days and the orbiter has been in orbit for 379 days. The two are in good condition and functioning properly.

The report provides no other real information.. I have indicated on the map to the right the range in which this travel distance could have taken Zhurong. Hopefully they will release more information soon.

The nominal mission was originally planned for 90 days. Right now it looks like the rover will easily exceed that.

SpaceX stacks Starship on top of Superheavy

Superheavy with Starship on top
Click for original image.

Capitalism in space: Only three days after the company had rolled Superheavy prototype #4 to the launchpad, SpaceX today stacked Starship prototype #20 on top, uniting for the first time the entire rocket.

All told, the rocket is 395 feet high, about 32 feet taller than the Saturn-5.

The photo to the right, reduced slightly to post here, was posted by Elon Musk earlier today. It also makes obvious several things that will be different for this Starship flight compared to the previous suborbital hops. Starship’s dark exterior is because it is covered with thermal tiles designed to protect it as it returns to Earth flying through the atmosphere at orbital speeds.

Note also the grid fins on Superheavy. Apparently they will be open during the entire flight, instead of unfurling shortly after stage separation as is done with Falcon 9.

I am not sure what the vertical attachments near the bottom of Superheavy are for. The plan is for the stage to land in the Gulf of Mexico, so it does not need landing legs. Could these be attachment points for holding the rocket to the launchpad?

I have been predicting a late September/early October date for this rocket’s first orbital launch test. SpaceX is sure working hard to beat that timeline. They still need to do tank tests and static fire tests of the whole assembly, but based on past schedules, they might get this done in only a few weeks. If so, it means they might be able to launch before the end of August.

My god, if only other American rocket companies worked in this manner. Imagine what wonders they all could accomplish.

Astra to attempt orbital launch later in August

Capitalism in space: The smallsat rocket company Astra has announced that it will attempt to complete its first successful orbital launch before the end of this month, launching a Space Force satellite.

The U.S. Space Force has booked two missions with Astra, the Bay Area company announced today (Aug. 5). The first flight will launch a test payload for the Department of Defense’s Space Test Program from the Pacific Spaceport Complex in Kodiak, Alaska, during a window that runs from Aug. 27 through Sept. 11.

Astra has two previous test launches that attempted to reach orbit and failed. The second barely missed, because of a fuel mixture issue that had it run out of fuel prematurely.

If successful, this will make Astra the third operational American smallsat rocket company, following Rocket Lab and Virgin Orbit. Four others have promised launches in 2021. By next year the competition in this smallsat launch industry should be quite fierce.

Virgin Galactic reopens suborbital ticket sale, raises price, delays next flight

Capitalism in space: Virgin Galactic announced yesterday that it is resuming ticket sales for flights on its reusable SpaceShipTwo spacecraft, raising the price from the old price of $250,000 to a new price of $450,000.

Virgin Galactic is offering customers three options: purchase a single seat, buy several together or book an entire flight on the eight-passenger Unity (or other space planes that come into operation, such as the recently built VSS Imagine). The company also sells seats for microgravity research and professional astronaut training. Those are in a different tier, going for $600,000 apiece, Colglazier said during a call with investors on Thursday afternoon.

The announcement also revealed that they are delaying their next flight until September. That flight has been scheduled for the summer for months. The company is also delaying the start of regular commercial flights until late in ’22, in order to make some upgrades to their spacecraft.

By that time, regular orbital tourist flights will have become almost routine. Moreover, one has the option to experience weightlessness for far less buying a ticket on one of the various companies that fly “vomit comet” airplanes.

One wonders if the demand for these flights will be sustainable. We shall see.

China launches military communications satellite

China’s Long March 3B rocket yesterday successfully launched a military communications satellite.

This was China’s eighth government launch since the beginning of July, in a span of only five weeks.

The launch was from an interior spaceport, so the rocket’s strap-on boosters and first stage core landed within China. No word if any landed near or on habitable areas, or if the Chinese were using parachutes or grid fins to control their landing.

The leaders in the 2021 launch race:

26 China
20 SpaceX
12 Russia
3 Northrop Grumman
3 Rocket Lab

The U.S. still leads China 30 to 26 in the national rankings.

Ingenuity successfully completes 11th flight

Ingenuity about to land
Click for full image.

Ingenuity has successfully completed its 11th flight, safely touching down at approximately its planned landing spot. From the science team’s tweet:

[Ingenuity] has safely flown to a new location! Ingenuity flew for 130.9 seconds and traveled about 380 meters before landing.

The image to the right, reduced to post here, was taken mere seconds before landing, and shows the helicopter’s shadow directly below it on the ground.

This particular flight was the first that did not push Ingenuity’s abilities, merely flying in a straight line to put it in a good position for later flights and to keep it ahead of Perseverance.

So far they have only released five images from the flight. Expect the rest to be downloaded from Perseverance in the next few days.

As thousands of teachers endorse critical race theory, home schooling surges

What apparently Critical Race Theory sees as education for elementary school kids.
What apparently Critical Race Theory sees as education for
elementary school kids.

In the past few months state legislatures across the country have passed resolutions that ban schools from teaching the Marxist and bigoted program dubbed Critical Race Theory (CRT).

Not surprisingly, the leftists who dominate our school systems have fought back. The very leftist Zinn Education Project immediately created a petition calling for teachers to defy such laws and to continue to teach CRT, which teaches children to hate whites and to give minorities privileged status.

In the two months this petition has been on line almost 6,000 teachers have signed it, with many adding comments of defiance. This one is typical:

Curiosity: Nine years since landing on Mars and the way forward

The way forward for Curiosity
Click for full image.

In today’s Curiosity update written by planetary geologist Abigail Fraeman, she noted this significant fact:

Project scientist Ashwin Vasavada pointed out a great fact at the beginning of planning today: At around 4 o’clock in the afternoon on Sol 3199 (the first sol in the plan we are creating today), Curiosity will begin its 10th Earth year on Mars. In the last nine years, the rover has traveled 26.3 km [16.3 miles], climbed over 460 m [1,509 feet] in elevation, and collected 32 drilled samples of rock.

Her update includes the first image taken by Curiosity upon landing, a view of Mount Sharp using the rover’s front hazard camera. In that picture, the mountain is far away, as the rover was sitting on the flat floor of Gale Crater.

The photo above, cropped and enhanced to post here, was taken yesterday by one of Curiosity’s navigation cameras, and looks out across the rocky mountainous terrain the rover is soon to travel. As Fraeman also notes,

China’s Long March 6 launches two military technology test satellites

Using its Long March 6 rocket, China yesterday successfully placed two military technology test satellites into orbit, designed to test “new interference suppression technology for Ka-band mobile communications satellites.”

The launch occurred at one of China’s interior spaceports. No word on whether the rocket’s first stage crashed near habitable area.

The leaders in the 2021 launch race:

25 China
20 SpaceX
12 Russia
3 Northrop Grumman

Details on the Russian movie to be shot on ISS in October

Link here. The article provides a lot of details about who will fly, who will do what, and who is slated as back-ups if the primary crew of actress and director fail their training. However, I found the description of the movie to be the most interesting thing:

Shipenko revealed the script is still being fine-tuned, but the plot involves a cosmonaut who suffers a cardiac arrest during a spacewalk and, although he survives, he will require surgery to ensure he can handle the Soyuz return to Earth. A female cardiac surgeon, named Zhenya, has to be sent to the ISS to perform the procedure with only a few weeks to prepare for the trip.

Unlike the American space films like Gravity, this story is incredibly well grounded in reality. The Russians have actually experienced examples of station astronauts getting so sick in space that their missions had to be aborted early. In one case it was a prostate infection. In another it was the mental illness of the entire crew.

This story is also comparable to situations that have occurred in Antarctica, a very similar environment to the station. In the early 2000s the doctor in Antarctica had to perform surgery on herself because she had developed cancer. Then in 2016 Buzz Aldrin had to be evacuated due health issues.

If done right, this could not only make a damn good movie, it will also do so by revealing the true dangers of going to space.
