Audit finds SLS unlikely to launch in 2018

4:00 am

A NASA audit has found that it is unlikely that the first SLS test flight will take place as scheduled in 2018, and that the first manned flight is also likely to be delayed from its 2021 launch target.

“NASA’s first exploration missions — EM-1 and EM-2 — face multiple challenges that will likely delay their launch,” the report states. The missions “are not likely to launch by 2018 or 2021, respectively,” it continues.

When might a crew launch? Hard to say.

The report says incomplete NASA information makes it “more difficult for both the agency and external stakeholders to gain a full understanding of the costs of that mission or to assess the validity of the agency’s launch date assumptions.”

If the first manned flight happens in 2023, as now expected, it means that it will occur 20 years after George Bush first proposed the Crew Exploration Vehicle (Orion) and the heavy lift rocket to put it into space. The total cost to fly this one mission will be approximately $43 billion.

Let me repeat that: $43 billion and 20 years to fly a single manned mission. Does no one in government see something wrong with this picture?

China launches advanced communications satellite

9:28 pm

China today successfully launched an experimental communications satellite, outfitted to test the use of ion engine attitude thrusters as well as ground-to-orbit laser communications tests.

The article also outlines China’s busy launch schedule in April, which will include the launch and first test flight of their Tianzhou-1 cargo freighter. That flight will test the freighter’s ability to rendezvous and dock with their Tiangong-2 test space station module. This article notes that the freighter has been mounted on its Long March 7 rocket in preparation for launch in mid-April.

I must say that I am very glad to get out of Newark Airport. Though they have recently upgraded the airport, they have done so at the cost of providing affordable services to the traveler. All the restaurants there are very over-priced, and provide tiny portions. I actually ended up eating two dinners at two different restaurants in order to get enough food, and paid almost $40 for the pleasure. In addition, the tip was automatically added to the bill. I had no choice about that, even though the service was routinely bad. (They had installed tablets at every table so that you could order by computer. Getting a waiter to provide water however was practically impossible, and when I did get one they were slow to bring it.)

In addition, there were no fast food restaurants, which I normally avoid but would have been a far better choice in this case.

Newark is part of the New York urban area, a decidedly leftwing Democratic enclave. Thus, I am not surprised that things there cost too much, provided poor service, and also provided few choices.

First Falcon Heavy side first stage ready for initial tests

9:11 pm

Capitalism in space: SpaceX prepares for first Falcon Heavy launch this fall, with the first side stage ready for its first hot fire static tests while the company prepares the launchpads.

They need to finish repairing the launchpad damaged in the September 1 explosion so that the Falcon 9 can once again launch from there. Once this is done, they have an estimated sixty days of additional work to do with the Falcon Heavy pad. It is expected the switch back to the old pad will take place by August. meaning that the first Falcon Heavy launch will likely happen no earlier than October.

China and South Korea agree to counter North Korea’s missile/nuclear program

9:33 am

Under pressure from the Trump administration to do something about North Korea’s out-of-control and aggressive nuclear and missile program, China has worked out an agreement with South Korea to take “strong action”.

It remains a question how serious this response will be, but it is also the first sign in a long time that China is finally taking the threat from North Korea seriously.

Update: China refuses acceptance of coal from a fleet of North Korean ships.

This new story confirms that China was serious about this ban when it announced it in February. Set to run to at least the end of this year, the loss of income to North Korea, very poor already, should have some influence there. Whether good or bad, however, remains unknown. One cannot expect irrational and mad individuals holding great power to come to rational conclusions.

Turkey moves to create its own space agency

9:22 am

The new colonial movement: A draft bill to create a Turkish space agency has been introduced in that country’s parliament.

The Turkish Space Agency, according to the draft bill, will also be in charge of coordinating, managing, and operating all satellite requirements, design, manufacture, launch, and operations in Turkey, as well as coordinating private Turkish industries towards those goals. Jane’s Defence Weekly reports that the draft bill for the Turkish Space Agency has previously been held up for years due to a dispute between the Turkish military and several Turkish administrations as to who should be the lead within the agency. The draft bill in front of parliament suggests that the military have lost that argument, doubtless because of the aftermath of the July 2016 attempted coup, and instead it will take the lead on technical issues rather than policy and strategy.

Aerojet Rocketdyne trims and reorganizes workforce

9:07 am

Capitalism in space: In an effort to reduce costs and increase efficiency Aerojet Rocketdyne is cutting approximately 300 jobs while closing facilities in California and Virginia.

Rancho Cordova’s nearly 70-year run as a hub of the aerospace industry will soon end. On Monday, Aerojet Rocketdyne Inc. announced that it would relocate or eliminate about 1,100 of its 1,400 local jobs over the next 2 1/2 years and shut down manufacturing operations in the area. The company also said it would close its facility in Gainesville, Va.

Rocket engine manufacturing will be consolidated in a new plant in Huntsville, Ala. In all, 800 jobs will be added in Huntsville by the end of 2018.

The company is faced with stiff competition from Blue Origin and others, and until now has resisted changing its methods of operation, which in the past relied on generous government contracts that were uninterested in lowering costs. That world appears to be ending, and so it appears that the Aeroject Rocketdyne is finally changing as well. This is a good thing, as it increases the chances that the company will survive.

Scientists find persistent cold spot on Jupiter

8:59 am

In reviewing data for the past fifteen years have scientists have identified an unexpected cold region in Jupiter’s upper mid-latitudes as large as the Great Red Spot.

“The Great Cold Spot is much more volatile than the slowly changing Great Red Spot, changing dramatically in shape and size over only a few days and weeks, but it has re-appeared for as long as we have data to search for it, for over 15 years,” Stallard said. “That suggests that it continually reforms itself, and as a result it might be as old as the aurorae that form it – perhaps many thousands of years old.”

The Great Cold Spot is thought to be caused by the effects of the magnetic field of the planet, with the massive planet’s spectacular polar aurorae driving energy into the atmosphere in the form of heat flowing around the planet.

Though they think the cold region is related to the aurora, I suspect they really do not have enough information to really understand what is going on.

Sweden delivers science instrument for Chinese lunar probe

8:54 am

The new colonial movement: The Swedish Institute of Physics has completed construction and delivered a science instrument to be flown on China’s Chang’e 4 spacecraft that will bring an orbiter, lander, and rover to the Moon’s far side in 2018.

The instrument will be installed on the rover, and will study the surface and how it interacts with the solar wind. This will also be a continuation of research performed by India’s Chandayaan-1 orbiter.

New Horizons goes back to sleep

8:43 am

The New Horizons science and engineering team has placed the spacecraft back in hibernation mode for the first time since prior to its fly-by of Pluto in 2014.

During hibernation mode, much of the New Horizons spacecraft is unpowered. The onboard flight computer monitors system health and broadcasts a weekly beacon-status tone back to Earth, and about once a month sends home data on spacecraft health and safety. Onboard sequences sent in advance by mission controllers will eventually wake New Horizons to check out critical systems, gather new Kuiper Belt science data, and perform course corrections (if necessary).

This hibernation period will last until September, when they will wake the spacecraft so that they can make a mid-course correction in preparation for the January 1, 2019 flyby of Kuiper Belt Object 2014 MU69.

The storms of Jupiter

9:26 am

The storms of Jupiter

Cool image time! The image on the right, taken by Juno during its fifth close fly-by of Jupiter in late March and cropped to post here, shows two of the major storms in what I think is one of Jupiter’s main large mid-latitude belts. The full image, posted below in a significantly reduced form but annotated by me to indicate the location of the inset, covers a much larger area, but I have specifically zoomed into these two storms to highlight how large these storms are as well as how much detail is hidden within them.

In the bright spot in particular (officially called A6 by planetary scientists) you can see a hint of the existence of innumerable mini-storms. Juno’s camera does not have the resolution to image these smaller storms, but this image suggests that the gas giant’s atmosphere is far far far more complex than we can yet imagine.

Full image of Jupiter reduced and annotated

Unfortunately, these images do not provide a scale. Based on a global image taken by Juno in October 2016 and matching the gas giant’s major horizontal bands, the annotated full image strip on the left appears to cover a little less than a third of Jupiter, from about 10 degrees latitude to about 50 degrees latitude. From this I estimate that if we put the Earth in the inset image it would probably be only slightly larger than the image itself, which means these two storms would cover most of one hemisphere.

In other words, the mini-storms inside the big bright oval are still larger than the biggest hurricanes on Earth, and they are packed together inside a much larger planet-sized storm.

What should fill us with even more awe is that this only covers a very thin slice of the top of Jupiter’s deep atmosphere. The planet itself is about 89,000 miles in diameter, more than ten times larger than Earth. The depth of its atmosphere is not really known, but it must be deeper than several Earths, piled on top of each other. In that depth there must be many atmospheric layers, each thicker and denser than the one above, and each with its own weather systems and complexities.

It will take centuries of research, including the development of new engineering capable of accessing this place, to even begin to map out its meteorology. And this is only one gas giant, of what we now know must be millions and millions throughout the galaxy.

If we have the nerve and daring, the human race has the opportunity to go out there and never be bored. There will always be something unknown to discover.

Soyuz returns ISS crew to Earth

8:12 am

A Russian Soyuz capsule safely returned three astronauts to Earth this morning.

This completes the second flight of the Soyuz-MS upgraded capsule.

The new MS series sports more efficient solar panels, a new Kurs NA approach and docking system weighing less than half that of its predecessor, additional micro-meteoroid debris shielding, and a modified docking and attitude control engine – which will add redundancy during docking and deorbit burns.

ULA slashes launch prices for Atlas 5

9:12 am

Capitalism in space: In order to compete with SpaceX ULA announced this week that it will cut its launch price for the Atlas 5 rocket by one third.

United Launch Alliance has dropped the price of its workhorse Atlas 5 rocket flights by about one-third in response to mounting competition from rival SpaceX and others, the company’s chief executive said on Tuesday. “We’re seeing that price is even more important than it had been in the past,” Tory Bruno, chief executive of United Launch Alliance, or ULA, said during an interview at the U.S. Space Symposium in Colorado Springs. “We’re dropping the cost of Atlas almost every day. Atlas is now down more than a third in its cost,” Bruno said.

It appears that they have discovered that the prime reason they lost their bid of an Air Force GPS satellite launch to SpaceX was because their price was too high.

Air Force willing to use re-used Falcon 9 first stages

9:09 am

Capitalism in space: The head of the Air Force’s space division said yesterday that they would be willing to launch satellites using Falcon 9 used first stages.

“I would be comfortable if we were to fly on a reused booster,” General John “Jay” Raymond told reporters at the U.S. Space Symposium in Colorado Springs. “They’ve proven they can do it. … It’s going to get us to lower cost.”

Hubble snaps close-up of Jupiter

4:08 pm

Jupiter by Hubble

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.

ULA prepares to choose engine for Vulcan

7:21 am

Capitalism in space: ULA’s CEO Tory Bruno announced at a space conference this week that should Blue Origin’s BE-4 engine pass its testing phase his company will be prepared to select it for their Vulcan rocket.

Bruno also said that no decision has yet been made, and that Aerojet Rocketdyne’s AR1 engine remains an option, though it is 18 to 24 months behind in development.

Russia proposes extending ISS beyond 2024

7:13 am

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.

  • Their shortage of cash will make it difficult for them to fly their own station.
  • They need a space station in order to maintain the jobs that exist at their mission control as well as throughout their space industry.
  • There are many good political reasons for them to maintain this space partnership with the U.S. It prevents the U.S. from completely breaking off relations, should Russia do something the U.S. doesn’t like (such as invading a nearby country).
  • They recognize that the ability to do long term research in an orbiting space station is essential for anyone who plans future interplanetary missions.

I will let my readers decide which of these reasons are the good reasons, and which are bad.

Orbital ATK developing new rocket

6:38 am

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.

ULA reduces workforce at Vandenberg

9:23 pm

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.

ULA gets three launch contracts

8:41 pm

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.

Bad solder joints cause of Russian Proton engine defects

8:49 am

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.

SpaceX recovers fairing of upper stage of Falcon 9

8:34 am

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.”

SLS faces more delays

5:34 pm

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.

Practically every Russian Proton rocket engine defective

4:36 pm

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.

A tour of Vector Space Systems

4:31 pm

Jim Cantrell and cars

[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.

Vector test first stage

Vector first stage engine

second 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.”

bumper sticker

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?
