Why I use Linux

2:27 pm

Linux can be a pain sometimes, and it requires a bit more hands-on work by the user to make it function, but overall in the ten years since I abandoned Windows and switched to Linux (first with the Debian operating system and now with Kubuntu) I have found my work on my computer to be far more satisfying and successful. I can mostly get things done the way I like to do them, not as dictated by some software geek working at Microsoft’s headquarters.

Which is why this story interested me: “I thought my daughter clicked on ransomware – it was the damn Windows 10 installer.” It describes a number of stories where Windows 10 took control of a person’s computer and imposed an upgrade, against their will.

This story, among many others, only confirmed for me that my decision in 2006 was a wise one. I will never return to Windows, and if I was certain that computer projectors could read Linux laptops I’d switch the laptop to Linux as well.

It is just a shame however that so many people still stick with Windows, as it often makes doing their work difficult, if not impossible. When a product doesn’t work for you, you find another product. That’s how freedom and competition work.

SpaceX’s second first stage barge landing

9:10 am

Below is video of the Falcon 9 first stage landing last night. There isn’t really much to see, because this happened at night. However, I must repeat that this happened at night. In other words, SpaceX was able to bring its first stage down accurately in the middle of the ocean onto a tiny barge in the dark.

Who says the impossible is not possible?

During the live telecast, the audience broke out into a chant of “USA! USA!”, as they did after the previous first stage landings. Can you guess why?

Does Trump have the best space policy?

8:59 am

This opinion column looks at the three remaining politicians campaigning for president, and finds that Donald Trump probably has the most favorable position toward commercial space.

While all three candidates mouth favorable platitudes towards NASA and space exploration, all three also express reluctance to fund a giant government space program. Trump however was the only one to note the positive aspects of commercial space and express

…support for the government partnering with private space companies like Elon Musk’s SpaceX. “I think there needs to be a growing partnership between the government and the private sector as we continue to explore space,” Trump told AIAA. “There seems to be tremendous overlap of interests so it seems logical to go forward together.”

Obviously, one can’t and shouldn’t put much faith in what any politician says during the campaign. Nonetheless, this might be a hopeful sign that if elected, Trump would push to dump NASA’s SLS/Orion and have NASA instead focus on buying space exploration services designed and operated by private companies.

SpaceX lands the first stage again!

12:08 am

The competition heats up: In tonight’s launch, SpaceX not only put a commercial satellite into geosynchronous orbit, it successfully landed the first stage on a barge, a landing they did not expect to succeed.

Go here to watch a launch replay. The landing is at about 38 minutes.

With this success, I think they have demonstrated that they can recover that first stage in almost every circumstance. The next big challenge: Launch Falcon Heavy and recovering all three of its first stages.

Luxembourg signs deal with asteroid mining company

10:32 am

The competition heats up: As part of its outer space development program, the government of Luxembourg has signed a deal with asteroid mining company Deep Space, Inc. to build an orbital demonstration test satellite.

The inaugural project of this exciting new partnership is Prospector-X™, an experimental, low Earth orbit technology demonstration mission, designed to test the company’s innovative deep space technology. These key enabling technologies will be instrumental to the success of the company’s first deep space resource exploration missions in the near future. The Prospector-X spacecraft will be built at Deep Space Industries’ new European headquarters, in Luxembourg, in conjunction with the company’s international and American partners, including the Interdisciplinary Centre for Security, Reliability, and Trust (SnT) at the University of Luxembourg.

It essentially appears that Luxembourg is creating its own space program, focused entirely on profit by acting as the venture capitalist for private commercial companies. Most interesting.

Congressman proposes major changes to regulation of commercial space

9:46 am

Doug Messier has posted a detailed analysis of Congressman Jim Bridenstine’s (R-Oklahoma) proposed American Space Renaissance Act (ASRA) that is definitely worth reading.

Most of the changes appear aimed at organizing the regulation process of commercial space more completely under FAA control, rather than the hodge-podge of agencies that presently have responsibility. The bill also encourages NOAA and NASA to increase their use of commercial data for weather and Earth remote sensing.

At first glance, the bill looks good, but it also is not likely to be passed as written. Moreover, not surprisingly it calls for a hefty increase in funding for the FAA agencies being given more responsibilities, but I wonder if Congress will comparably reduce the funding of those agencies it takes responsibility from. My instinct tells me no, which means of course that the government and bureaucracy grows again.

SpaceX gears up for first Falcon Heavy flight

9:27 am

The competition heats up: SpaceX has already begun construction of one of the booster cores for its first test flight of Falcon Heavy, and expects to have all built by summer.

They have not yet decided on the payload or goal of that first test flight, though they appear to still be aiming for an November launch.

Meanwhile, they have a 1:21 am (eastern) Falcon 9 commercial launch tonight, in which they will also attempt another first stage barge landing.

NASA signs engineering test agreement with new launch company

10:52 am

The competition heats up: NASA has signed an agreement to provide testing facilities to Generation Orbit so it can do test flights of its air-launched rocket.

Generation Orbit Launch Services, Inc. (GO) is pleased to announce the signing of a Space Act Agreement with NASA Armstrong Flight Research Center (AFRC) to collaboratively pursue the flight test and envelope clearance for the GOLauncher 1 air launched rocket vehicle. Utilizing AFRC’s experience and capabilities in flight test engineering for air launch rocket systems, the two year program will demonstrate integration of the GOLauncher 1 Inert Test Article (GO1-ITA) with NASA’s Gulfstream III research aircraft, captive carry flight testing, and release testing. Further, NASA AFRC will continue the development of its store separation analysis capability, eventually validating the toolset through release flight testing of the GO1-ITA.

Like many similar past SAA agreements, NASA will provide no money, but will make its facilities available for testing at no charge. For a new company like this, this availability will help them enormously, and is more in line with what NASA was originally designed to do.

Why Russian aerospace will not compete

8:57 am

The fallout from the scrub and one day delay of the first launch at Vostochny, while Vladimir Putin was there and watching, has generated an investigation and the suspension of one designer.

The official goal of the commission was to find causes of the failed launch attempt and to check the completeness of tests leading to the incident.

However given a minor technical impact of the delay, the investigation likely had the primarily political nature, namely it was aimed to demonstrate to the Kremlin that the industry problems were being dealt with. Moreover, Rogozin also made a decision during the work of the commission to suspend the responsibilities of Leonid Shalimov, the designer general at NPO Avtomatika, which supplied the hardware allegedly responsible for the incident. Rogozin summoned Shalimov to Moscow on May 6, apparently to present the results of the investigation. [emphasis mine]

When you develop any new system or cutting edge technology, things are certain to go wrong. This is the one certainty that I will admit to and gladly embrace, and to which good designers, scientists, and engineers all agree. Vostochny is brand new. It stands barely finished. No launch had ever been attempted there before. For there to be a one day delay because of a minor engineering issue is hardly a sign of poor workmanship. Instead, it suggests the people who built it did a reasonably good job, even as many of their managers ripped them and the project off.

What we see here is an industry that is being run not by people who understand the business, but by distant politicians whose only interest is power and control. Can you imagine any manager in Roscosmos anywhere being willing to approve the start of a radical new engineering project, faced with pressure from Putin and these power-hungry politicians in Moscow? It won’t happen. Until there is a change and the politicians let go of their control of this industry, Roscosmos is going to take the safe route every single time.

Nothing new is going to come from Russia’s aerospace industry for a very long time.

SpaceX updates its prices

9:03 am

The competition heats up: SpaceX this weekend updated the prices and listed capabilities for buying a Falcon 9 launch, while also adding the price and capabilities of its not-yet flown Falcon Heavy. Here’s the link to the SpaceX page.

The damage shakes out to $62 million for a Falcon 9 rocket launch with a payload of 4,020 kilograms (8,860 pounds) and $90 million for a ride on the much-anticipated Falcon Heavy rocket, set to debut in late 2016, which can ferry 13,600 kilograms (29,980 pounds) to Mars. In addition to adding an interplanetary destination to its wares, SpaceX has also upped the payload capacity of the Falcon 9 to low Earth orbit from 29,000 pounds to over 50,000 pounds.

The Falcon Heavy is expected to put slightly more than 50 tons into low Earth orbit, half of what a Saturn 5 could do, and about two thirds what the first version of SLS will be able to do. Yet, their price to buy a launch is actually less than what every other rocket company is charging for rockets approximately comparable to the Falcon 9 and about 500 times less than the cost to build that SLS rocket (what an SLS actually costs to launch is anybody’s guess, but it certainly ain’t anywhere near $100 million). And the upgrades on the Falcon 9 have also made it better than those other rockets because it can now put 25 tons into low Earth orbit, only slightly less than the space shuttle.

That they have added the Falcon Heavy is also more evidence that they are confident that its first test flight will be this year.

Money for space

9:35 am

The competition heats up: Three stories today about investors putting money into different space related business ventures are worth consolidating into one post, as they all indicate the same thing.

The first story involves a takeover by SES of the O3b satellite constellation that provides internet service globally. They already have 12 satellites in orbit, and have plans to launch 8 more by 2019. A partial list of their customers (Digicel Pacific, Royal Caribbean Cruise Lines, American Samoa Telecom, Speedcast, Rignet, Bharti International (Airtel), Timor Telecom, CNT Ecuador, Entel Chile and NOAA) illustrates the solidity of the company’s success, which is also why SES is spending $20 million to own it.

In the second two stories we find investment capital being committed for two different and unusual space-tourism-related companies. World View plans to launch high altitude balloons with passengers, taking them up 20 to 30 miles for a several hour journey on the edge of space. That they have secured an additional $15 million in investment even as their deal with the city of Tucson is being challenged in court indicates the confidence the investors have in their business.

SpaceVR is even more interesting. They plan to launch smallsats with cameras providing a 360 degree view, and link them to virtual reality headsets here on Earth. Consumers will then be able to experience being in space, without actually going. Though the press release does not specific how the product will be sold, it suggests that they are aiming for the education and museum market.

All three stories prove that the modern investment community, normally very adverse to high risk endeavors, is increasingly finding that the financial benefits of space travel and anything related to it are worth the financial risks. This fact can only lead to good things for the eventual development and exploration of space.

Moreover, the third story once again demonstrates the value of reducing the cost to get into orbit. SpaceVR’s idea is a very good one, but it couldn’t have happened before SpaceX forced a reduction in launch prices. Beforehand, no one could have afforded to buy the product because of the high cost to launch the satellites. Now, because the launch price is affordable, it can be marketed at a realistic price.

In other words, lower the price, and you increase the number of customers able to buy your product. I expect the rocket business to boom in the coming years.

SpaceX gets its first official Air Force contract

8:52 am

The competition heats up: On April 27 the Air Force made it official and announced that SpaceX has won its first military contract, breaking ULA’s launch monopoly.

This contract award really isn’t a surprise, as SpaceX had been certified by the Air Force as a qualified bidder, and ULA had declined to bid on this particular contract, leaving SpaceX as the Air Force’s only possible contractor.

Update: The Air Force has admitted that SpaceX’s $83 million price is 40% less than what ULA has typically charged for a comparable launch, confirming what Elon Musk and SpaceX (and many others, including myself back in 2005) have claimed all along, that the Air Force’s EELV bulk buy (giving ULA an Air Force launch monopoly) was a bad idea, discouraging innovation, forcing costs up, and guaranteed to force the government to spend a lot of unnecessary extra money.

I must add that it is definitely worthwhile reading my UPI column from 2005 again, now, more than a decade later. I predicted quite accurately what has subsequently happened following the merger of Lockheed Martin and Boeing to form ULA.

Billy Joel and Michael Pollack – New York State of Mind

6:01 pm

An evening pause: Hat tip Frank Kelly. As Frank emailed me, “Student Michael Pollack asks Billy Joel if he can accompany him on piano, playing New York State of Mind. Billy Joel accepts and asks, “What key do you play it in.” Pollack: “What key do you want it in?” Just from that Joel can tell he can play, then Pollack starts playing, and this is important, when he starts, Joel instantly knows he’s [good]. Perhaps he realizes he might be a reason this kid learned piano. Joel is a bit amazed, watch it, he relaxes and just lets Pollack do his thing; he even makes a flamboyant point of putting his sunglasses on.”

Or as Joel says at the end, “The guy’s got chops.” Stick with it, it only gets better.

Tallest tunnel slide to open in London

9:43 am

A reason to go to London: The world’s tallest tunnel slide, almost 600 feet long and 250 feet high, is being built as part of a sculpture that was part of the 2012 Olympic games location.

Once complete, the slide will be 178-m (584-ft) long and 76-m (249-ft) high, making it, according to the ArcelorMittal Orbit, the “world’s tallest and longest tunnel slide.” Riders will experience 12 twists and turns, including a tight corkscrew section called the “bettfeder,” which is German for “bedspring.” The slide ends with a 50-m (164-ft) straight stretch to the ground.

It is estimated that it will take about 40 seconds for people to descend the slide, with riders expected to hit speeds of up to 15 mph (24 km/h). On the way down, there will be dark sections, as well as points where it will be possible for riders to see out of transparent polycarbonate windows, providing brief views out over the Olympic Park and surrounding areas.

Dragon to go to Mars in 2018

9:33 am

The competition heats up: Though no details have yet been released, SpaceX has announced through its twitter feed that they plan to send a Dragon to Mars by 2018.

This is not really a surprise, as rumors have been circulating literally for years of Musk’s Martian goals. Nor am I doubtful they can do it. What is important about this announcement is that it suggests that they are now confident that the delays for the first Falcon Heavy launch are mostly over, and that it will happen in the fall as presently planned. With this rocket they will have the launch capability to do a test flight to Mars.

April 25, 2016 Zimmerman Space Show appearance

10:43 am

My appearance on the Space Show yesterday is now available as a podcast. I strongly recommend people listen to it, especially the first hour. During that section I compared at length the cost and practicality of the Falcon Heavy with SLS/Orion, and noted how badly Congress and Presidents from both parties have served the American people these past twenty years in mismanaging our aerospace industry.

David Livingston called it a rant, and criticized me for it during the show, but I think the time has come for more Americans to rage in horror at the foolishness and possible corruption of our elected leaders in Washington.

A close look at Falcon 9’s reusable cost savings

10:33 am

Link here.

The analysis is interesting and thoughtful, though some of the negative comments quoted from a former NASA engineer only illustrate why NASA was unable to do this very well. Moreover, these comments from Arianespace’s chief suggest that Arianespace doesn’t understand basic economics.

Arianespace Chief Executive Stephane Israel, in an April 23 briefing at Europe’s Guiana Space Center here on the northeast coast of South America, said Europe’s launch sector can only guess at how much SpaceX will need to spend to refurbish its Falcon 9 first stages. Israel said European assessments of reusability have concluded that, to reap the full cost benefits, a partially reusable rocket would need to launch 35-40 times per year to maintain a sizable production facility while introducing reused hardware into the manifest.

…Israel’s argument, which he has made before, is that even if first stages can be recovered and refurbished in a cost-effective way, the launch rate needed for maximum cost savings – and hence price reductions to customers – is beyond Europe’s reach. The only nations today whose governments are launching sufficiently often to reach those rates are the United States and China, and even these government markets may be insufficient, in and of themselves, to close the business case.

The customer base is not static. If you lower the price, the customer base grows, a fact that Elon Musk understands and which has been driving his effort from day one.

New smallsat rocket company obtains financing

9:59 am

The competition heats up: A new rocket company, Vector Space Systems, has announced that it has obtained seed money to begin the development of a new rocket for launch very small satellites.

Vector is designed to provide dedicated launches of very small spacecraft. The vehicle is capable of placing satellites weighing up to 45 kilograms into a basic low Earth orbit, and 25 kilograms into a standard sun synchronous orbit. Those launches will cost $2–3 million each, with the higher price reserved for “first class” launches reserved as little as three months in advance.

This rocket would compete with Virgin Galactic’s LauncherOne and Rocket Lab’s Electron for the smallsat and cubesat business.

Problems at Stratolaunch?

9:39 am

In the heat of competition: Vulcan Aerospace, the company building the giant Stratolaunch airplane designed launch orbital rockets from its underbelly, does not yet have a rocket for this purpose.

Originally that rocket was to be built by SpaceX, but that partnership ended in 2012.

Stratolaunch then contracted out its rocket work to Orbital Sciences Corp. (now Orbital ATK). The company also contracted with Aerojet Rocketdyne for six RL10C-1 rocket engines with an option for six more for use in the launch vehicle’s third stage.

The agreement with Orbital ended without the production of a launch vehicle, with Beames saying the rocket was not economical. Stratolaunch officials said they were reassessing the project in light of the shift in the market recently toward smaller satellites.

In 2015, Beames said that Stratolaunch was examining more than 70 launch vehicles for use with the Stratolaunch aircraft. He indicated that the company might use multiple launch vehicles to serve different payload classes. Beames said the company would announce its launch vehicle strategy in fall 2015, but that time came and went with no announcement. [emphasis mine]

It is very worrisome for them to be hunting for a rocket at this point of design. I am reminded of Virgin Galactic and SpaceShipTwo, which changed engine designs midstream, causing them enormous engineering problems and delays.

Orbital ATK negotiating lease for part of VAB

9:36 pm

The competition heats up: Orbital ATK has begun negotiations with NASA for possibly leasing part of the Vehicle Assembly Building (VAB) for use in connection with a military rocket.

Virginia-based Orbital ATK is one of two rocket companies that launch resupply missions to the International Space Station, but this deal would not involve those missions or that rocket, the company’s Antares. The Antares launches from NASA’s space port at Wallops Island, Va., carrying the Orbital ATK Cygnus capsule.

The new rocket that Orbital ATK hopes to develop and one day assemble in the VAB would be a medium- to heavy-lift rocket.The planned rocket currently referred to by the name the Air Force set for it, the Evolved Expendable Launch Vehicle-class rocket.

It sounds like Orbital ATK is putting together a bid to compete for the Air Force rocket contract, and needs to get a handle on the costs for using the VAB at Kennedy in order to make the offer credible.

Largest jet engine ever test fired

9:31 am

The competition heats up: General Electric has completed the first test firing of the largest airplane jet engine ever built.

With a front fan spreading a full 11 ft (3.35 m), the GE9X is a world record holder and generates thrust in the order of 100,000 lb. To accommodate the aeronautical behemoth, the Peebles facility was recently upgraded with a larger air intake, extra fuel tanks to feed the giant engine, and high temperature gear to deal with the hotter, more efficient design.

GE says that the GE9X is currently undergoing its first Full Engine To Test (FETT). This is the next level of the test series, which began in 2011 at the component level, and marks the first test of the complete system, which comes only six months after the engine design was finalized. GE says that this relatively early testing was to ensure that the test data was available as soon as possible for the certification engines, which are scheduled to be installed in GE Aviation’s flying test bed for certification of flight testing in 2018.

OneWeb satellite factory coming to Florida

9:00 am

The competition heats up: OneWeb officially announces its plan to build its satellite factory in Florida.

OneWeb Satellites LLC prepares to break ground on its new estimated $85 million high volume satellite manufacturing factory in Exploration Park, Florida. Announced during a ceremony with Florida Governor Rick Scott and OneWeb founder Greg Wyler, the factory near NASA’s Kennedy Space Center is set to open in 2017, with delivery of initial satellites later that year or early the next. OneWeb Satellites is a joint venture between OneWeb, a satellite based internet provider, and Airbus Defence and Space, the world’s second largest space company.

I think this news report of the press conference notes the most important aspect of this satellite factory, its assembly-line approach:

Typically, communications satellites take four to five months to assemble, Brian Holz, chief executive of OneWeb Satellites, a joint venture of OneWeb and Europe’s Airbus Group’s Defense and Space said during an event near the future location of the factory. “We’re going to build one in an eight-hour shift,” he said. He did not give details but said the factory would be highly automated.

If all goes right, they should begin launch satellites in large numbers within two years, which will mean a lot of additional launch business for the smallsat rocket industry.
