An evening pause: I like this verse, which they reprised, with the chorus, which all people should echo.
When Britain first, at Heaven’s command
Arose from out the azure main;
This was the charter of the land,
And guardian angels sang this strain:
“Rule, Britannia! rule the waves:
“Britons never will be slaves.”

Cool image time! The Hubble Space Telescope has taken a magnificent global view of Jupiter. The image on the right is only a thumbnail. Make sure to go to the link to see the full image, which amazingly compares quite favorably with the images being sent down by Juno in orbit around the gas giant.
This Hubble image once again demonstrates the remarkable advantages of an optical telescope in space. Equipped with the right instruments, it could do much of the research now being done by the planetary missions, and do it from Earth orbit.The research possibilities and the knowledge revealed from the ability to see things clearly in the optical bands is truly endless.
Even more important, we are wired to what we see. Give us a good visual image and many questions can immediately be answered.
Capitalism in space: Two stories today highlight the contrasts that presently exist within the still unborn suborbital tourist industry:
In the first, Richard Branson made another one of his bold predictions, the same kind of prediction he has been making about Virgin Galactic now for almost a decade. Again and again he claims, based on nothing, that his spaceship will be carrying people into orbit in mere months. It never happens. It won’t happen here.
In the second, Jeff Bezos announces that he hopes to fly people on his New Shepard suborbital spacecraft by 2018, but at the same time he also announces that the program is delayed.
Bezos, speaking in front of the company’s exhibit at the 33rd Space Symposium here that features the New Shepard propulsion module that flew five suborbital spaceflights in 2015 and 2016, backed away from earlier statements that called for flying people on test flights later this year. “We’re going to go through the test program, and we’ll put humans on it when we’re happy,” he said. “I don’t think it’s going to be 2017 at this point. It could be.”
Bezos has been very careful, from the beginning, to make no bold or specific predictions about when his spacecraft will fly manned. Here, he is once again making it clear that any previously announced schedules were very tentative, and should not be taken too seriously.
Which person would you trust with your life on a suborbital flight?

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.
“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of the Mars Society.

The head of Roscosmos said at a space conference this week that his nation is open to extending its ISS partnership with the U.S. beyond 2024 to 2028.
Russia has several good and bad reasons for wanted to do this.
I will let my readers decide which of these reasons are the good reasons, and which are bad.
Capitalism in space: Orbital ATK is developing a new rocket, based on the solid rocket technology it provided for the space shuttle, to compete with SpaceX and ULA.
Two versions of the rocket are planned. The medium-lift variant will have a two-segment, solid-fuel first-stage motor and a single-segment, solid second. The heavy lifter will have a four-segment first stage and a single-segment second. Both versions can be outfitted with strap-on boosters for extra lift capacity, Orbital representatives said.
To complete the rocket’s development the company says it needs to win a follow-up contract that the Air Force has been issuing to help ween the U.S. from the use of Russian rocket engines.
Capitalism in space: In an effort to save costs ULA is reducing its workforce at Vandenberg by 48.
The company has been aggressively trying to streamline its operations to better compete against SpaceX. This reduction was expected, and based upon what I saw when I toured Vandenberg a few years ago, entirely justified. While SpaceX’s operations then looked lean and simple, ULA’s set up appeared a bit inefficient.
Capitalism in space: A new commercial satellite company, Global-IP Kayman, has purchased a Falcon 9 rocket to launch its first Boeing-built satellite late in 2018.
No word on whether the launch will use a reused first stage.
Since flying past Pluto in July 2014 New Horizons has now flown halfway to its next target, Kuiper Belt Object 2014 MU69.

ULA has finally scheduled the much delayed Atlas 5 launch of Orbital ATK’s Cygnus ISS freighter for April 18.
Posted from Maswik Lodge on the south rim of the Grand Canyon.
Capitalism in space: ULA last week won three launch contracts, two from the Air Force and one from NASA.
Both rockets are part of the existing EELV Block Buy between the Air Force and United Launch Alliance. The mission assignments were announced Friday by the Pentagon. The missions exceed the lift performance of the SpaceX Falcon 9 rockets that has been certified by the Air Force for national security payloads, making ULA the only provider available to execute these heavy launches.
In other government-launch news, NASA said last month that the second satellite in the next-generation era of U.S. civilian weather observatories will be launched atop an Atlas 5-401 rocket. The Atlas 5 beat out the Falcon 9 in a competition to win the rights to launch the Joint Polar Satellite System spacecraft No. 2 in 2021 from Vandenberg Air Force Base.
For SpaceX to truly compete with ULA they need to get the Falcon Heavy flying.

A bunch of stories from Russia today appear to express that country’s political response to SpaceX’s success yesterday in launching a commercial satellite using a previously flown first stage.
It appears that these stories are quoting a variety of Russian officials who apparently did not get their stories straight. Also, it appears that much of what they are saying here is pure bluster. For example, in the third link the official makes the silly claim that the ability of their rocket engines to be started and then restarted repeatedly proves they are dedicated to re-usability. And the first two links don’t provide much back-up for the claims that they can complete with SpaceX, especially since SpaceX presently charges a third less than they do per launch, and that is using new boosters. With reused boosters SpaceX’s launch fees will be less than half what Russia has been charging for a Proton launch ($90 million vs $40 million).
Similarly, the claim that they will complete 30 launches this years is absurd. They won’t be able to launch Proton until May, at the soonest, because of the need to remove defective parts from all of their in-stock engines. Soyuz launches are similarly delayed while they check its engines also. To complete 30 launches in only seven months seems very unrealistic to me, especially since the best they have done in a full year this century is 34 launches, with an average slightly less than 30 per year.
Nonetheless, this spate of stories and statements by Russian officials shows that they are feeling the heat of competition, and also feel a need to respond. The first story has this significant statement:
Russia’s State Space Corporation Roscosmos is responding to the challenges with available possibilities, he added. “It has announced a considerable reduction in the cost of Proton rocket launches. The commercial price of this rocket’s launch is considerably higher than its prime cost and we have the potential for the price cut. But customers are giving up our services because the number of payloads [satellites] remains unchanged and does not grow. Correspondingly, a new player on the market snatches away a part of orders,” the expert noted.
Because of Russia’s low labor costs they have always had a large profit margin on their Proton launches. The $90 million they charged was set just below what Arianespace charged for its launches. It appears they are now planning to lower their prices further to match SpaceX.

The competition heats up: SpaceX plans to use two already flown first stage boosters when it does its first demo flight of Falcon Heavy later this year.
Musk said the rocket cores for Falcon Heavy’s first flight are two to three months away from completion. He emphasized that the first launch will carry a lot of risk, and as such, SpaceX doesn’t plan to carry a valuable payload or payloads with it. “We will probably fly something really silly on Falcon Heavy because it is quite a high risk mission,” he said.
SpaceX will seek to recover all the boosters from the first Falcon Heavy flight, assuming all goes according to plan. Musk said the two side boosters would land back at Cape Canaveral Air Force Station, followed by the center core returning to a drone ship in the Atlantic.
They will also try to recover the upper stage, but are not hopeful this will succeed. The article also notes that they hope to fly an additional four used boosters in 2017. SES is eager to use them on its three scheduled flights this year.
The company has also said that the booster that was successfully reused this week will not fly again, but will instead be put on display in Florida.

The problem that has forced the Russians to recall all Proton second and third stage engines has been identified as the use of the wrong materials in solder joints.
According to specifications, the structural walls and the nozzle chamber of the gas generator had to be fused together with the help of the solder designated G70NKh, which employs nickel, chromium and manganese alloy (Ni-Cr-Mn). However the investigation revealed that due to mismanagement of the raw material usage at the Voronezh Mechanical Plant, the required alloy had been replaced with the PZhK-1000 solder comprised of palladium, nickel, chromium and silicon (Pd-Ni-Cr-Si). Because the replaced solder did not meet specifications, it could lead to structural disintegration of the nozzle head during the firing of the gas generator.
The discovery of the problem with the solder triggered inspection of other engines and revealed that all RD-0210 and RD-0212 engines from the second and third stages that had been manufactured during 2015 and 2016 had been equipped with defective gas generators. In order to re-certify these engines for flight, each of them would have to be disassembled, the gas generator would have to be removed and replaced, followed by the re-assembly and re-testing of each engine!
The article also notes that the next Angara rocket is also “unfit for flight” due to unspecified defects. It also notes widespread corruption and mismanagement throughout the Russian aerospace industry.
Sadly, the decision by the Putin administration to consolidate their industry into one huge corporation run by the government, and thus eliminate any competition, is only going to make solving this problem more difficult. What Russia needs is competition, with many different companies free to challenge each other for business. It also needs to allow companies to fail and go out of business.
Instead, everything is controlled from above, and thus no competition can happen. Rather than finding a new company to build these engines, the government is going to provide the company “economic aid” in order to modernize it. This is like putting a band-aid on a broken bone.
The competition heats up: Even as SpaceX made history yesterday in its successful use and recovery of a used first stage, it also recovered for the first time the fairing that protected the satellite.
For the first time, SpaceX also recovered the payload fairing, the conical shaped structure on top of the rocket that surrounds and protects the spacecraft during launch. The fairing separates from the spacecraft in two sections during the launch sequence — in this case, 3 minutes and 49 seconds after launch — and usually falls into the ocean and breaks into pieces. SpaceX outfitted these two fairing sections with parachutes so they could be recovered, which apparently will become standard practice.
Musk also indicated that they are now going to begin an effort to recover the second stage. “What’s the worst that could happen? It blows up? It would anyway.”
An evening pause: The video focuses on a shuttle launch, but I think the words apply to all launches, and especially to those that break new ground.

Delays by ESA in the construction of the service module for Orion, plus the tornado damage at the Michoud facility in Louisiana, could force NASA to delay the first unmanned test launch of the SLS rocket, presently planned for late in 2018.
NASA is also considering delaying the flight further should the agency decide to make this first unmanned test flight a manned one. They also say they will need more money if they have to put people on the first flight. I guess $43 billion and almost 15 years wasn’t enough.
By the way, it took less than four years to win World War II. From Kennedy’s speech to the Apollo 11 landing was only eight years. One wonders when we, as a nation, will finally wake up and realize that SLS is not a rocket to the Moon, but an never-ending jobs program unable to accomplish anything in space.
New data from the Mars atmospheric probe MAVEN has confirmed that much of Mars’ atmosphere was stripped away over the past few billion years by the solar wind.
This result confirms data from Curiosity, but adds the detail that the solar wind was a major component in causing the loss of atmosphere.
The investigation of the Russian supply of rocket engines for its Proton rocket has discovered that practically every engine, numbering over seventy, had defects that needed repair.
71 engines, mostly used to power the second and third stages of the Proton rocket, require complete overhauls to remove defects. Arbuzov did not specify what was wrong with the engines. In January, Interfax reported on an investigation into high-quality metals swapped by a plant manager for cheaper alternatives. “Most of the work will be done in 2017, but we understand that some portion will inevitably slip into 2018,” Arbuzov said. “Our main goal is to avoid disrupting the government space program’s launch schedule, or the schedules of the Defense Ministry and commercial customers.”
There is also the possibility that these defects will be found in Soyuz rocket engines as well. Stay tuned.
[UPDATE: I have been informed by Vector’s PR department that they have recently changed the company’s name, dropping “Space Systems” from the title. I can’t really change the title here, but I thought I note this fact for my readers.]
Today I got a quick tour of Vector Space System’s very blue collar but active rocket factory in Tucson, Arizona. My tour guide was Jim Cantrell, the CEO of the company.
Cantrell, shown on the right in front of one of his side businesses fixing and refurbishing race cars and rare luxury sports cars (also located in this factory), started out with a love of race cars, which he still builds and races. As he said to me, “Long endurance car racing is still my thing.”
However, he has also spent his life in the space business. He has worked for government agencies and numerous private businesses, including SpaceX at its very beginning. Vector Space Systems is an effort put together by him and several other people to capture the smallsat market, a market he truly believes is going to explode with activity in the coming years. If things go as he wishes, they hope to launch at least one hundred times a year, from multiple launch sites. Their goal is simplicity and quick turnaround at an inexpensive cost.
The company is presently in the testing phase leading up to their first orbital launches, which they hope to start in 2018. Right now they are building a series of full scale versions of their Vector-R rocket with a dummy second stage. The idea is to do a string of suborbital test flights, the first of which will fly in about a week from Mohave in California, with the second flying from the Georgia spaceport in Camden County. The image below is the first stage of that first test rocket.
For this flight their main goal is to test the engine, which Cantrell is showing me in the picture to the right. I was astonished at how small and simple the engine was. In fact, the rocket itself was amazingly small. It looked like it could almost fit inside a typical moving truck.
Below and to the right is the first stage for their second test flight, presently being assembled. They hope it will be ready for flight in only a few weeks after the first flight. They plan five suborbital test flights, with the last capable of getting about 90% to orbit. Along the way they will test their avionics, the rocket’s balancing systems, and its computer and tanks. Once these tests are complete they will then move to testing the orbital version in 2018.
Obviously, all this depends on every test flight being successful. But then, even if something goes wrong they will learn something and move on. For example, they recently transported an engineering version of the rocket to the visitor center at Kennedy. As Cantrell explained, “We learned things new just making that move.”
In the end, I think the bumper sticker to the right, attached to the window of Vector Space System’s office, sums everything up. The people at Vector want to make money in space, but they — like everyone in the space business — also love making rockets and engines and going fast. What better combination from life could you ask for?
The competition heats up: SpaceX has successfully launched a commercial satellite using a previously flown first stage.
Even more important, they landed that first stage on a barge, and can even consider using it again!
The uncertainty of science: A new theory now shows that dark energy, the apparent acceleration of the universe’s expansion rate on large scales, does not need to exist in order to explain the data that astronomers have obtained.
In the new work, the researchers, led by Phd student Gábor Rácz of Eötvös Loránd University in Hungary, question the existence of dark energy and suggest an alternative explanation. They argue that conventional models of cosmology (the study of the origin and evolution of the universe), rely on approximations that ignore its structure, and where matter is assumed to have a uniform density. “Einstein’s equations of general relativity that describe the expansion of the universe are so complex mathematically, that for a hundred years no solutions accounting for the effect of cosmic structures have been found. We know from very precise supernova observations that the universe is accelerating, but at the same time we rely on coarse approximations to Einstein’s equations which may introduce serious side-effects, such as the need for dark energy, in the models designed to fit the observational data.” explains Dr László Dobos, co-author of the paper, also at Eötvös Loránd University.
In practice, normal and dark matter appear to fill the universe with a foam-like structure, where galaxies are located on the thin walls between bubbles, and are grouped into superclusters. The insides of the bubbles are in contrast almost empty of both kinds of matter. Using a computer simulation to model the effect of gravity on the distribution of millions of particles of dark matter, the scientists reconstructed the evolution of the universe, including the early clumping of matter, and the formation of large scale structure.
Unlike conventional simulations with a smoothly expanding universe, taking the structure into account led to a model where different regions of the cosmos expand at different rate. The average expansion rate though is consistent with present observations, which suggest an overall acceleration.
In other words, the uneven structure of the universe has never been considered in previous models, and once included in the equations the need for dark energy disappears.
Last night the National Interest posted an op-ed written by me and drawn from my policy paper, Capitalism in Space.
The title is “Private Space wins the Race.”
