Masten unveils two new reusable suborbital rockets
The competition heats up: Masten Space Systems has unveiled two new small reusable suborbital rockets, designed to be used for short research flights.
The new unmanned rockets can take off and land vertically, can be reused in a short amount of time, and and hover in mid-air. The approximately 15-foot rockets are a lot smaller than the reusable rockets that Blue Origin and SpaceX are launching, landing, and (in Blue Origin’s case) already reusing. They can’t travel as high or carry nearly as heavy of a payload, but they could prove to be useful for gathering science data in suborbital space.
The link has a short video showing the rockets in operation. Very impressive, even if small.
Elon Musk sends a tweet and the world listens
The competition heats up: Yesterday Elon Musk sent out a tweet that simply repeated something his company has been saying now for several months — but with one slight additional detail — and the press went gaga.
What Musk said was that SpaceX hopes to reuse one of its used Falcon 9 first stages by September or October. Previously they had merely said they were aiming to do it before the end of the year. Since SES has offered one of its satellites for the job, and since it has had for months two such satellites scheduled for launch by SpaceX in September and October, this announcement by Musk is not really much of a surprise. Yet, the tweet was enough for all of the following mainstream news sources to gin up news-breaking headlines:
- Nikkei Asian Review: SpaceX to launch reused rockets by year-end
- CNET: SpaceX aims to relaunch a rocket for the first time later this year
- Mashable: SpaceX aims to relaunch a used Falcon 9 rocket as early as September
- Los Angeles Times: SpaceX aiming to launch its first reusable rocket in the fall
- Popular Science: SpaceX Plans To Re-Use A Rocket For The First Time This Fall
- The Verge: SpaceX plans to relaunch a used rocket for the first time this fall
I am not really complaining. What I am really noting is how serious the world now takes what Musk and SpaceX are doing. They say they plan to do something new and revolutionary, and people sit up and take notice. And the reasons are twofold. First, everything they have said they were going to do, they have done. Musk’s announcement has to be taken seriously. Second, Musk owns SpaceX, and does not really need anyone’s permission to do this. He isn’t in a negotiation with numerous other players, as has been the case with NASA and its projects for the past half century. We know that if he wants to try something, the only things that could stop him are lack of capital and lack of good engineering, neither of which are an obstacle in this case.
So, be prepared for the first relaunch of a rocket’s first stage sometime this fall. And don’t be surprised if that isn’t the only new thing SpaceX accomplishes at the time.
FAA warns public of military GPS jamming tests
The FAA has issued a warning that GPS at high elevations may be unreliable during jamming tests being conducted by the U.S. military during June.
The FAA issued an advisory warning pilots on Saturday that global positioning systems (GPS) could be unreliable during six different days this month, primarily in the Southwestern United States. On June 7, 9, 21, 23, 28, and 30th the GPS interference testing will be taking place between 9:30am and 3:30pm Pacific time. But if you’re on the ground, you probably won’t notice interference.
The testing will be centered on China Lake, California—home to the Navy’s 1.1 million acre Naval Air Weapons Center in the Mojave Desert. The potentially lost signals will stretch hundreds of miles in each direction and will affect various types of GPS, reaching the furthest at higher altitudes. But the jamming will only affect aircraft above 5,000 feet. As you can see from the FAA map below, the jamming will almost reach the California-Oregon border at 40,000 feet above sea level and 505 nautical miles at its greatest range.
Elon Musk to meet with Defense Secretary
The competition heats up: A private meeting to discuss modern innovation between Elon Musk and Defense Secretary Ash Carter has been scheduled for Wednesday.
Ash Carter, the U.S. Secretary of Defense, and Elon Musk, SpaceX’s founder and chief executive, will discuss innovation June 8 in a private meeting, the Pentagon’s top spokesman said. “Elon Musk is one of the most innovative minds in this country and the secretary, as you know, has been reaching out to a number of members of the technology community to get their ideas, their feedback, find out what’s going on in the world of innovation,” Peter Cook, the Pentagon’s press secretary said during a June 6 briefing. “The secretary’s had a number of meetings with business leaders and innovation leaders in particular out in Silicon Valley, other parts of the country, and I think that’s his goal here: to hear directly from Elon Musk on some of these issues.”
The meeting is private, which means an agenda or discussion items are generally not released. More details were not immediately available.
I am sure about one thing: This meeting is going to make the corporate board of ULA very nervous.
The history of the stopwatch
Link here. The most fascinating part of this story is the recent discovery of the very first stopwatch, previously unknown, built in 1816, and remarkably similar to the standard analog stopwatches used for decades until the arrival of digital equipment.
The layout of the compteur also makes one suspect it ended up in 1816 via a time machine. Instead of inking paper, it has a silvered and frosted metal dial dominated by a large fraction-second hand like later stopwatches, and three subdials for marking hours, minutes, and whole seconds Along with this, the stopwatch has a button at 12 o’clock to start and stop it, plus an 11 o’clock button to instantly reset the dials. This is a feature common to modern stopwatches and one not thought to be invented until 1862 by Adolphe Nicole.
LISA Pathfinder proves space-based gravity wave detection technology
Engineers have announced that the gravity wave detection technology being tested in orbit by Europe’s LISA Pathfinder works.
To show that the necessary sensitivity is possible, LISA Pathfinder measures the distance between two masses, both of which are inside the spacecraft. “We’ve shrunk the arm of a large gravitational wave antenna to 35 centimeters so we could show it works properly,” Paul McNamara, LISA Pathfinder project scientist, told the press conference.
LISA Pathfinder was launched in December 2015 to a spot 1.5 million kilometers from Earth. When its test masses where first released to float free in February, “the relief was unbelievable,” McNamara says. Science operations began on 1 March and on that first day the team was able to measure distance variations between the masses much smaller than LISA Pathfinder’s mission requirements, Stefano Vitale, the mission’s principle investigator, told reporters. After a month, the variations were even smaller, “very close to [eLISA] requirements,” he says.
They now hope to launch an array of at least three such spacecraft by the mid-2030s.
Russia delays next manned Soyuz flight
Russia has confirmed previous reports and has officially delayed the next manned Soyuz launch to ISS from June 24 to July 7.
They remain vague about the issue causing the delay, this time only saying they want more time to test software. Previous reports suggested the issue was with the capsule’s control thrusters.
Meanwhile, no word on whether they have figured out why the upper stage on the previous Soyuz rocket launch shut down prematurely.
SpaceX lobbies Texas government for spaceport backing
The competition heats up: In testimony today before the Texas legislature, a SpaceX official called for more government funding to support the company’s spaceport construction in Boca Chica near Brownsville, Texas.
At a recent joint legislative committee hearing held at UT-Rio Grande Valley in Brownsville, Caryn Schenewerk, senior counsel and director of governmental affairs for SpaceX, pointed out that zero dollars were appropriated to the Texas Spaceport Trust Fund during last year’s legislative session. In contrast, Schenewerk said, Florida commits $20 million a year to its spaceport infrastructure fund.
“One of the things I want to highlight for you is that unfortunately, the spaceport trust fund was not funded in the 84th Legislature and we will certainly be advocating for it to be considered by the 85th and for it to be part of the budget in the 85th Legislature,” Schenewerk testified. “By contrast, Florida consistently funds its space infrastructure fund to a tune of $20 million a year. Those infrastructure matching grants go to exactly the kind of activities that we are undertaking at Boca Chica. They are public-private partnerships for investing specifically in what is so costly an undertaking, the infrastructure.”
Obviously, SpaceX’s spaceport is going to require an increased financial commitment by the state government to build and maintain the increased infrastructure that such large operations require. At the same time, SpaceX doesn’t need a handout. They shouldn’t expect the taxpayers to pay for their private spaceport.
The article does provide some updated information about the spaceport’s construction status. It looks like they are aiming for a 2018 launch date.
Titan over Saturn’s rings
Cool image time! The picture on the right, taken on January 26, 2016 by Cassini and reduced and cropped to show here, captures Titan above Saturn’s rings, which are themselves partly obscured by the shadow of Saturn (unseen on the right) that falls across them.
Make sure you go to look at the full image. This is the kind of vista that artists in the 1950s imagined we’d see once we began to explore the solar system.
Astronauts enter privately built BEAM module
Led by American Jeff Williams, two astronauts opened the hatch and entered Bigelow’s BEAM inflatable module on ISS today.
Williams officially opened the hatch at 08:47 UTC. Along with Russian cosmonaut Oleg Skripochka, Williams entered BEAM for the first time to collect an air sample and begin downloading data from sensors on the dynamics of BEAM’s expansion. The astronaut reported that the interior of BEAM looks “pristine”. However, he added the temperature was on the cool side – with Houston adding they recorded 44F as the temperature at bulkhead – but no condensation was visible. He then took air samples, as is the procedure for entering a new module.
They will install interior sensors over the next two days, and then shut the hatch. The module will then remain closed for most of its planned two year stay on ISS to test its operation in space.
The article also includes some nice details about the possible uses of Bigelow’s much larger B330 modules, two of which are under construction right now.
Why I won’t use Windows
A remote wildlife project in central Africa has been significantly hampered by the unwanted Windows 10 forced upgrades.
The Chinko Project manages roughly 17,600 square kilometres (6,795 square miles) of rainforest and savannah in the east of the CAR, near the border with South Sudan. Money is tight, and so is internet bandwidth. So the staff was more than a little displeased when one of the donated laptops the team uses began upgrading to Windows 10 automatically, pulling in gigabytes of data over a radio link.
And it’s not just bandwidth bills they have to worry about. “If a forced upgrade happened and crashed our PCs while in the middle of coordinating rangers under fire from armed militarized poachers, blood could literally be on Microsoft’s hands,” said one member of the team. “I just came here recently to act as their pilot but have IT skills as well. The guy who set these PCs up didn’t know how to prevent it, or set a metered connection. I am completely livid.”
As I’ve noted before, I have been using Linux for ten years. Though there have been some areas of annoyance (no software is perfect), I have not found myself limited in what I need to do, in any important matter. If you’ve got a spare older computer that you’re not using right now, install Linux on it and play with it. You will soon find that it does everything a Windows machine does, without the crap.
Luxembourg to invest $200 million in space mining
The competition heats up: The government of Luxembourg has budgeted $200 million to invest in private proposals to mine asteroids for profit.
This government commitment is different than other government space projects in that they are not creating a “space program”, they are literally acting as a venture capitalist, putting their money into private efforts in exchange for profit.
June 3, 2016 Zimmerman/Batchelor podcast
Embedded below the fold. I outlined some history of the Hubble Space Telescope, as well as provided some added context to why there was so much more press excitement surrounding the space plans of Elon Musk and Jeff Bezos, compared to the press disinterest in recent years of similar NASA proposals.

NASA signs Blue Origin for suborbital missions
The competition heats up: NASA has contracted with Blue Origin to use its New Shepard suborbital spacecraft for suborbital research missions.
The company hasn’t actually won any contracts, but is now certified to bid on any of NASA’s suborbital research work, as are Masten Space Systems, Near Space Corporation, UP Aerospace, Virgin Galactic, and World View Enterprise. The difference is that of all these companies, only Blue Origin has a ship built and already flying.
The Rosetta science team wants your help!
The scientists running Rosetta are asking the public to help them pour through the more than 20,000 images of Comet 67P/C-G to identify any changes the comet has undergone since the spacecraft’s arrival.
Why the Goldwater Institute sued to block Tucson space deal
Link here.
The fundamental reason is that the Institute believes that, in signing its deal with World View to build its headquarters and launch site in Tucson, Pima County violated several laws as well as Arizona’s constitution. We are supposed to be a nation of laws, and thus government officials should not be allowed to violate those laws, even if they have the best of intentions.
I must say that, though I have no doubt that putting World Views space tourism balloon company in Tucson would be financially good for the city and Arizona, allowing elected officials to break the law to make deals with private companies is a very bad way to do it, and will in the end lead to far worse consequences.
Falcon 9 first stage returns to port, with a noticable list
The competition heats up: The first stage from SpaceX’s most recent Falcon 9 launch returned to port today, showing a visible lean.
Musk said that the stage was probably OK, but there was some risk of tipping. This was due to the fact that the contingency “crush core” was used up. He described on Twitter that the crush core was an aluminum honeycomb for energy absorption in the telescoping actuator. Once the stage was within sight of land, it became clear that the booster had a noticeable lean to it, due to the aforementioned contingency crush core being used up. The ramifications of this are still unclear, but Musk’s tweet implied that the crush core is easily replaceable.
Why I use Linux, part 2
Microsoft has changed its options so that Windows users will no longer be able to refuse an upgrade to Windows 10.
Microsoft’s Windows 10 nagware campaign has entered a new phase, with all options to evade or escape an upgrade finally blocked.
Recently, Microsoft’s policy had been to throw up a dialogue box asking you whether you wanted to install Windows 10. If you clicked the red “X” to close the box – the tried-and-tested way to make dialogue boxes vanish without agreeing to do anything – Microsoft began taking that as permission for the upgrade to go ahead.
Now Microsoft is changing gears. It has eliminated the option to re-schedule a chosen upgrade time once you’ve confirmed it while also removing the red “X” close option from the screen.
The moral dishonesty here is vile, to put it mildly. Microsoft is enforcing these upgrades by offering a series of sneaky bait-and-switch options that are intentionally designed to fool the user into doing something the user doesn’t want to do. And the company is doing this while still claiming that it isn’t forcing anything on anyone.
When you find yourself dealing with a lying snake-oil salesman, you only have yourself to blame if you continue that relationship and get screwed.
Billionaires propose big space plans
At separate interviews given during a media conference held this week in California, Elon Musk and Jeff Bezos each expressed their thoughts about what they hope to accomplish in space over the next few decades.
- Factories in space: Amazon founder Jeff Bezos unveils vision for the future
- Elon Musk wants people on Mars by 2025
First, Jeff Bezos outlined his belief that, in order to protect the Earth, humanity is going to have to eventually move its heavy manufacturing off the planet and into space. He thought colonizing the planets was a cool idea, but his focus remained with Earth, and using space as a way to protect it.
Musk meanwhile revealed his company’s long range plans for Mars, including their firm intention to send a Dragon capsule to the red planet during every future launch opportunity, beginning with 2018. Each mission will provide information needed to improve and develop their engineering so that they can hopefully send humans there by 2024.
A realistic appraisal of both men’s proposals will quickly recognize that they are probably overly optimistic. Bezos might be right that we should move our heavy industries into space, but he is not realistic to think this can happen soon, or is even possible. Musk’s company SpaceX might be laying the groundwork for the eventual colonization of Mars, but to think it will begin happening by 2024 is unrealistic.
Still, what both men are proposing are things that they are personally helping to make happen. Neither man has to get anyone else’s permission or approval to push these dreams. All they need to do is make sure the products they are building for accomplishing these tasks can also make money by providing services to others. Since this is exactly what both men are doing, they will likely achieve far more than anyone can imagine, even if the specific proposals they are putting forth now do not happen in their lifetimes.
This bright and very possible future is far different than the powerpoint proposals that NASA and big government have offered to us over and over again for the past four decades. Those ideas, while also ambitious, could never happen because they were dependent on the approval of too many other players, Congress, the public, the press, the bureaucracy. They were not founded on profits, so they became a drain on the economy instead of a source of wealth. The result was that we have gone nowhere and developed little new space technology in the years since the last Apollo landing.
Only now, with our renewed reliance on capitalism and profits, are we finally beginning to see the dreams expressed in those NASA powerpoint proposals coming to life. And it isn’t the government that is making them happen, but free individuals, with big dreams and the will to pursue them.
Expect there to be privately funded manned missions to Mars in the next decade. And expect there to be factories in orbit, far sooner than anyone expects.
