SpaceX aims for December 29 launch of Falcon Heavy
Capitalism in space: SpaceX has set a date for the first Falcon Heavy launch as no earlier than December 29.
They hope to be able to do a number of dress rehearsal countdowns prior to actual launch, which is what makes this schedule somewhat tentative.
While SpaceX has ample experience lighting all nine engines of the Falcon 9 simultaneously, with every Falcon 9 going through a full duration hot fire at McGregor followed by a static fire on the launch pad before all nine engines are lit a third time for launch, no company in the U.S. rocket industry has experience lighting 27 engines at the same time.
While each of the three Falcon Heavy debut cores – two flight-proven cores for the side-mounted boosters (boosters B1023 and B1025) and a new core for the central core (booster B1033) – have undergone hot fire testing at McGregor, they were all fired separately because the Texas test site is not built to accommodate three cores at the same time.
This means SpaceX will not gain a full understanding of how all 27 engines light until the more-crucial-than-usual static fire at LC-39A at Kennedy.
Users blocked from files by Google Docs
Reason 4,320,333 why I do not use Google: Some users of Google Docs yesterday were blocked by the company from their files because of “terms of service violations.”
In response to some of these reports, a Google employee tweeted that the team handling Google Docs was looking into the matter. Later Tuesday, Google said in a statement that it had “made a code push that incorrectly flagged a small percentage of Google Docs as abusive, which caused those documents to be automatically blocked. A fix is in place and all users should have full access to their docs.”
Although the error appeared to be a technical glitch, the fact that Google is capable of identifying “bad” Google Docs at all is a reminder: Much of what you upload, receive or type to Google is monitored. While many people may be aware that Gmail scans your emails — for instance, so that its smart-reply feature can figure out what responses to suggest — this policy extends to other Google products, too.
Here’s what this story reveals: Google monitors the content of the files that people store on Google Docs. Google has also developed software that can decide if some of that content is acceptable or unacceptable, to Google. Google can then block access to those supposedly private files, thus giving it the power to silence the work of anyone the company doesn’t like.
Sounds peachy-keen, doesn’t it?
Scientists receiving EPA grants will no longer serve on EPA advisory panels
EPA head Scott Pruitt today announced that any scientist receiving EPA grants will no longer be allowed to serve on three EPA science advisory panels.
In the past three years, members of the Science Advisory Board, the Clean Air Scientific Advisory Committee, and the Board of Scientific Counselors received about $77 million in direct EPA grants while serving, according to agency calculations. “Strengthening independence from EPA; increasing state, tribal, and local government participation; and adding geographic diversity and fresh perspectives will improve the integrity of EPA’s scientific advisory committees,” Pruitt told reporters, government officials, and policy analysts in attendance.
The issue is a conflict of interest. These same scientists could not fairly advise EPA since they depended on that agency for major funding. The result was that these panels would often recommend the EPA to fund research that these scientists favored and were known to focus on, thus giving them an advantage in obtaining grants. Not surprisingly, this research often pushed the theory of global-warming and anti-industry regulation. This old-boy network for funneling funds to the right people, regardless of its legitimacy, is now hopefully cut off.
House on Haunted Hill
An evening pause: For Halloween tonight a slightly different treat: a full length movie! House on Haunted Hill (1958) starred Vincent Price, and was directed by William Castle. As Leonard Maltin put it, “Campy fun.”
NASA wants private company to take over Spitzer Space Telescope
NASA has issued a request for proposals from private companies or organizations to take over the operation of the Spitzer Space Telescope after 2019.
NASA’s current plans call for operating Spitzer through March of 2019 to perform preparatory observations for the James Webb Space Telescope. That schedule was based on plans for a fall 2018 launch of JWST, which has since been delayed to the spring of 2019. Under that plan, NASA would close out the Spitzer mission by fiscal year 2020. That plan was intended to save NASA the cost of running Spitzer, which is currently $14 million a year. The spacecraft itself, though, remains in good condition and could operating well beyond NASA’s current plan.
“The observatory and the IRAC instrument are in excellent health. We don’t have really any issues with the hardware,” said Lisa Storrie-Lombardi, Spitzer project manager, in a presentation to the committee Oct. 18. IRAC is the Infrared Array Camera, an instrument that continues operations at its two shortest wavelengths long after the spacecraft exhausted the supply of liquid helium coolant.
The spacecraft’s only consumable is nitrogen gas used for the spacecraft’s thrusters, and Storrie-Lombardi said the spacecraft still had half its supply of nitrogen 14 years after launch.
The way a private organization could make money on this is to charge astronomers and research projects for observation time. This could work, since there is usually a greater demand for research time than available observatories.
Minotaur-C successfully launches 10 commercial smallsats
Capitalism in space: Orbital ATK’s Minotaur-C rocket today successfully launched 10 commercial smallsats.
It appears that they have upgraded the accused Taurus rocket in renaming it Minotaur-C.
After Orbital ATK suffered a series of launch failures with the Taurus rockets — which led to the loss of NASA’s Orbiting Carbon Observatory as well as its Glory climate-monitoring satellite — the company redesigned the Taurus. The new and improved rocket uses newer and more reliable technologies that Orbital ATK had built for its other Minotaur rockets.
This success is a very good thing for Orbital ATK, as the rocket likely gives them a strong position in the emerging smallsat market.
New exoplanet defies accepted theories of planet formation
The uncertainty of science: A newly discovered exoplanet, the size of Jupiter and orbiting a star half the size of the Sun, should not exist based on all the presently favored theories of planet formation.
New research, led by Dr Daniel Bayliss and Professor Peter Wheatley from the University of Warwick’s Astronomy and Astrophysics Group, has identified the unusual planet NGTS-1b – the largest planet compared to the size of its companion star ever discovered in the universe.
NGTS-1b is a gas giant six hundred light years away, the size of Jupiter, and orbits a small star with a radius and mass half that of our sun.
Its existence challenges theories of planet formation which state that a planet of this size could not be formed by such a small star. According to these theories, small stars can readily form rocky planets but do not gather enough material together to form Jupiter-sized planets. The planet is a hot Jupiter, at least as large as the Jupiter in our solar system, but with around 20% less mass. It is very close to its star – just 3% of the distance between Earth and the Sun – and orbits the star every 2.6 days, meaning a year on NGTS-1b lasts two and a half days.
No one should be surprised by this. While the present theories of planet formation are useful and necessary, giving scientists a rough framework for studying exoplanets, they should not be taken too seriously. We simply do not yet have enough information about how stars, solar systems, and planets form.
SpaceX completes installation of two antenna dishes in Boca Chica spaceport
Capitalism in space: SpaceX has completed the installation of two ground station antenna dishes in its Boca Chica spaceport that will be used to facilitate communications with its manned Dragon missions.
A SpaceX spokesman said the antennas will also be used to track flights from Boca Chica once they’re underway. The company acquired the 86-ton antennas from NASA’s Kennedy Space Center at Cape Canaveral and transported them to Boca Chica via semitrailer. The first antenna was installed this summer.
The article also implies that SpaceX plans to eventually launch manned missions from Boca Chica.
Satellite data business to grow to $8.5 billion by 2026
Capitalism in space: An industry analysis says that the satellite data market should grow to $8.5 billion by 2026, with the potential to reach $15 billion.
Euroconsult has identified approximately 20 companies that have announced intentions to develop lower-cost constellations to collect data at a high rate of revisit based on smallsat and cubesat technologies. As of 2017, these new operators have attracted more than U.S.$600 million in venture capital to fund their initiatives. None of the newly announced initiatives have yet reached full capacity; for these constellations to come to fruition, additional investments will be required.
Competition is expected to be fierce on the supply side, as companies must differentiate themselves in the marketplace and bring innovative solutions to maintain market share. Consolidation (such as MDA and DigitalGlobe, OmniEarth and EagleView, Terra Bella and Planet) could linger as companies refine business models and continue to seek investments. DigitalGlobe, for example, is aiming to add a lower-cost satellite constellation (Legion) to its portfolio to counter the probable impact of low-priced solutions entering the market. Airbus will also develop its own very high resolution (VHR) optical system, given that the next generation French defence system will not be commercialized.
Astronomers find 20 more exoplanet candidates in Kepler archive
Worlds without end: Astronomers reviewing the Kepler archive have found 20 more exoplanet candidates, including one that has a mass about 97 percent of the Earth with an orbit 395 days long circling a star like the Sun.
The planet would be colder than Earth, as its star is slightly cooler than the Sun, and its orbit is slightly farther away. Nonetheless, this is an amazing twin, and would certainly be a prime target when interstellar travel becomes routine.
Orbital ATK to launch first Minotaur-C in six and a half years
Capitalism in space: Orbital ATK will try today to successfully launch its renamed Taurus rocket, six and a half years after its previous two launches had ended in failure.
The rocket is now called Minotaur-C and will attempt to launch ten Planet Lab smallsats. As Taurus, the rocket failed 3 times out of 9 launches, and from what I could tell watching the launch industry, was basically a dead product. I am now astonished that it is coming back to life. Apparently, Planet Lab got a good launch price, and can take the risk since its smallsats represent a relatively small investment and can be replaced much more easily than the two research satellites (Orbiting Carbon Laboratory and Glory) that NASA lost in the rocket’s previous two launches more than half a decade ago.
The article outlines nicely the history of this rocket, and how its failures significantly set back the growth of Orbital ATK. Hopefully, it will succeed now, and provide the U.S. another player in the increasingly competitive global launch market.
