Used Dragon to fly in 2017
The competition heats up: SpaceX has confirmed that they will reuse a Dragon capsule to bring cargo to ISS in the spring of 2017.
This plan had already been revealed earlier. The news here is simply that NASA and SpaceX have finalized the decision and picked the actual schedule cargo mission that will use a Dragon capsule. What is more significant is this:
SpaceX plans to reuse Dragon spacecraft through the remainder of its current CRS contract, which runs through SpX-20. [Benjamin Reed, SpaceX director of commercial crew mission management] did not discuss how many Dragon spacecraft are available to be reused, or how many times SpaceX believes a Dragon capsule can be flown.
If successful, Reed said it would allow SpaceX to end production of the cargo Dragon spacecraft. “We’ll be reflying Dragons going forward, and be able to close down the Dragon 1 line and move all the way into Dragon 2,” he said, referring to the next-generation version of the Dragon being developed for commercial crew missions.
In other words, their goal is to transition very quickly from disposable capsules to a fleet of capsules that they fly over and over again.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The print edition can be purchased at Amazon or any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News
Schiaparelli lander successfully separates from orbiter
In preparation for its Mars landing on October 19, Schiaparelli has successfully separated from the Trace Gas Orbiter of the European/Russian ExoMars 2016 mission.
They had some initial communications issues soon after separation, all of which have now been resolved.
China launches two astronauts on 30-day space station mission
China today (Monday in China) launched two astronauts successfully on a 30-day mission to their second space station, Tiangong-2.
They have not yet docked with the station.
Now available in hardback and paperback as well as ebook!
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.
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.
“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.
All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount. All editions can also be purchased direct from the ebook publisher, ebookit, in which case you don't support the big tech companies and the author gets a bigger cut much sooner.
Autographed printed copies are also available at discount directly from the author (hardback $29.95; paperback $14.95; Shipping cost for either: $6.00). Just send an email to zimmerman @ nasw dot org.
Problems with Juno’s main engine
Valve problems detected during Juno’s orbital insert around Jupiter has caused engineers to delay the October 19 engine burn that would have lowered the probe’s orbit around Jupiter.
Mission managers for NASA’s Juno mission to Jupiter have decided to postpone the upcoming burn of its main rocket motor originally scheduled for Oct. 19. This burn, called the period reduction maneuver (PRM), was to reduce Juno’s orbital period around Jupiter from 53.4 to 14 days. The decision was made in order to further study the performance of a set of valves that are part of the spacecraft’s fuel pressurization system. The period reduction maneuver was the final scheduled burn of Juno’s main engine. “Telemetry indicates that two helium check valves that play an important role in the firing of the spacecraft’s main engine did not operate as expected during a command sequence that was initiated yesterday,” said Rick Nybakken, Juno project manager at NASA’s Jet Propulsion Laboratory in Pasadena, California. “The valves should have opened in a few seconds, but it took several minutes. We need to better understand this issue before moving forward with a burn of the main engine.”
Because of this, they will instead use this next close approach to Jupiter to do pure science, something that they would not have done during the engine burn. Though this is a good example of turning lemons into lemonade, it will not be a good thing if Juno can never reduce its orbit to 14 days. A 53 day orbit will mean that they can only do good research every two months, and will seriously limit what they can learn over the long run.
Antares launch delayed by faulty cable
Orbital ATK has delayed its first launch in two years of its redesigned Antares rocket after discovering a cable needed to be replaced during prelaunch tests.
The launch is now scheduled for 7:40 pm (Eastern) Monday.

Good distractions
My posting this week has been somewhat slack, mostly because I am trying to finish up a caving monograph for a survey project that has been on-going for the past five years. I have also been swamped with the very last changes to my policy paper for the Center for New American Security, which now has the title Capitalism in Space: Private Enterprise and Competition reshape the Global Aerospace Launch Industry. (I am hoping that title causes a few liberal heads to explode when the paper is released in the coming days.) I am also off on another cave project this weekend, so I will not be posting again until Sunday night.
Hopefully, things will ease up next week. In the meantime, enjoy your weekends and do not get too depressed over the insanity and madness that appears to be taking over our society.

The intolerant religion of peace
No matter how peaceful and friendly and tolerant the majority of Muslims might be, their religion continues to attract and generate the most intolerance and hate and violence worldwide. Below are just a few stories in the past 24 hours that illustrate the increasingly vicious nature of Islam:
- The Temple Mount and Western Wall – Judaism’s holiest site – are reclassified as exclusively Muslim by the UN in major victory to Palestinian cause
- Pakistan – 150 Sunni Muslim Clerics issue death Fatwa for Christian Asia Bibi
- Palestinians: “We Are Proud of You. You Killed Jews!”
This is only three stories. If I wanted, I could have listed dozens, from all over the world, all giving examples of Islamic hate for and violence against anyone that is not a practitioner of that religion.
In the first story, the UNESCO declaration that these Jerusalem sites are exclusively Muslim didn’t only rub out thousands of years of Jewish history, it also wiped out thousands of years of Christian history as well. As has been historically typical of Islam, it cannot tolerate other religions. When Islam conquered Israel it did not respect the site of the Jewish Second Temple, it instead immediately built its own temple on top of it, claimed ownership, and has since worked to exclude Jews and Christians from the site. Now Muslim countries are trying to use the UN to strengthen their claim and to justify their effort to remove all Jews from the Middle East, an effort that is well illustrated by the .third story.
Vanishing Obamacare plans
Finding out what’s in it: More than a million people are losing their health insurance plans this year as insurers increasingly flee Obamacare.
The number above was determined by
At least 1.4 million people in 32 states will lose the Obamacare plan they have now, according to state officials contacted by Bloomberg. That’s largely caused by Aetna Inc., UnitedHealth Group Inc. and some state or regional insurers quitting the law’s markets for individual coverage.
…Nationwide estimates of the number of people losing their current plans are higher. For example, Charles Gaba, who tracks the law at ACASignups.net, estimates that 2 million to 2.5 million people in the U.S. will lose their current plans, compared with 2 million a year ago. Gaba’s estimate is based on insurance company membership data.
For the people losing plans, there are fewer and fewer choices. One estimate by the Kaiser Family Foundation predicts that for at least 19 percent of the people in Obamacare’s individual market next year there will be only one insurer to choose from.
Obviously, the solution is to ask the people that wrote this bad law to fix it. We should all vote Democratic on election day, and help make this disaster even worse!
Kaguya data released at last
Seven years after the mission ended Japan has finally released the full catalog of images and videos taken by its lunar orbiter Kaguya.
No explanation for the long delay has been provided. Overall, this is just another example of what to me appears to be a bloated, bureaucratic, and slow to move Japanese space program. Their rockets are expensive, their planetary probes have had repeated problems, and they seem to be very uninterested in stepping up their game to compete in the increasingly competitive international race to explore and settle the solar system. That it took them more than seven years to release this data is quite shameful.
ExoMars 2016 bearing down on Mars
This article provides a detailed look at Sunday’s arrival of ExoMars 2016 at Mars.
If all goes right the Schiaparelli lander will soft land on the surface while the Trace Gas Orbiter will enter an initial 185 by 60,000 mile orbit, which will slowly be adjusted so that by January it can begin its atmospheric research.
Though the Russian contribution to this mission was only the rocket that sent it to Mars, if the mission succeeds it will be the first time any Mars mission with major Russian participation has succeeded. The failure rate for any Russian effort to go to Mars has been 100%. And it hasn’t been because the missions have been particularly difficult. The majority of their failures occurred in the 1960s and 1970s, even as they were very successfully completing much harder lander missions to Venus.
It has almost as if there is a curse against any Russian attempt to visit the Red Planet. Hopefully, that curse will finally be broken on Sunday.
No more manned Soyuz purchased by NASA after 2019
The competition heats up: Both Boeing and SpaceX better get their manned capsules working by 2019, because NASA at this point has no plans to buy more seats on Russian Soyuz capsules after the present contract runs out.
Even as the commercial crew schedules move later into 2018, NASA officials say they are not considering extending the contract with Roscosmos — the Russian space agency — for more launches in 2019. The last Soyuz launch seats reserved for U.S. astronauts are at the end of 2018.
It takes more than two years to procure components and assemble new Soyuz capsules, so Russia needed to receive new Soyuz orders from NASA by some time this fall to ensure the spacecraft would be ready for liftoff in early 2019.
The second paragraph above notes that even if NASA decided it needed more Soyuz launches, it is probably too late to buy them and have them available by 2019.
Details on Starliner changes
This article provides some details about the design changes being made to Starliner that have caused its first test flight to be delayed until 2018.
André Rieu – The Beautiful Blue Danube
An evening pause: What I think makes these performances by Rieu and his orchestra so especially appealing is that he finds musicians who are glad to show how much they enjoy playing this lovely music. He recognizes the importance of fun.
And yes, as a child of the 1960s, I cannot help listening to this music and see spaceships docking. Those of my generation will of course immediately know to what I am referring. Will anyone younger?
Hat tip Edward Thelen.
New power source for planetary missions?
Research at JPL has developed new materials called skutterudites that have the potential of increasing the efficiency and power output of the radioisotope electric generators used on deep space missions where solar power will not work.
The new eMMRTG would provide 25 percent more power than Curiosity’s generator at the start of a mission, according to current analyses. Additionally, since skutterudites naturally degrade more slowly that the current materials in the MMRTG, a spacecraft outfitted with an eMMRTG would have at least 50 percent more power at the end of a 17-year design life than it does today.
“Having a more efficient thermoelectric system means we’d need to use less plutonium. We could go farther, for longer and do more,” Bux said.
This being NASA research, they are moving somewhat slowly in testing and confirming whether these new materials will work. They hope that after passing further reviews in 2017 and 2018 the agency might finally approve their use in subsequent missions.
Ten times more galaxies than previously believed
The uncertainty of science: A new analysis from Hubble and other telescope data suggests that the universe actually contains ten times more galaxies than previously estimated, several trillion instead of the past estimate of 100 to 200 billion.
I would not bet much money on this conclusion. I suspect that further research will find even more galaxies, since our deep observations of the universe are at the moment confined to a mere handful of Hubble deep field images that cover only a few tiny specks of space.
This new analysis however did confirm previous estimates that suggest the universe has evolved and changed significantly over time.
In analysing the data the team looked more than 13 billion years into the past. This showed them that galaxies are not evenly distributed throughout the Universe’s history. In fact, it appears that there were a factor of 10 more galaxies per unit volume when the Universe was only a few billion years old compared with today. Most of these galaxies were relatively small and faint, with masses similar to those of the satellite galaxies surrounding the Milky Way.
These results are powerful evidence that a significant evolution has taken place throughout the Universe’s history, an evolution during which galaxies merged together, dramatically reducing their total number. “This gives us a verification of the so-called top-down formation of structure in the Universe,” explains Conselice.
Breakthrough increases plant yields by one third
Plant scientists have found a way to encourage plants to better use atmospheric nitrogen, thus increasing yields by more than one third.
For years, scientists have tried to increase the rate of nitrogen fixation in legumes by altering rhizobia bacterioid function or interactions that take place between the bacterioid and the root nodule cells.
Tegeder took a different approach: She increased the number of proteins that help move nitrogen from the rhizobia bacteria to the plant’s leaves, seed-producing organs and other areas where it is needed. The additional transport proteins sped up the overall export of nitrogen from the root nodules. This initiated a feedback loop that caused the rhizobia to start fixing more atmospheric nitrogen, which the plant then used to produce more seeds. “They are bigger, grow faster and generally look better than natural soybean plants,” Tegeder said. “Some evidence we have suggests they might also be highly efficient under stressful conditions like drought.”
The technique not only produces healthier plants and more seeds, it reduces the need for fertilizer, the overuse of which can be an environmental issue.
The Moon gets pounded more than expected
The uncertainty of science: A close review of Lunar Reconnaissance Orbiter (LRO) images now suggests that asteroid impacts occur 33% more than previously estimated.
The research also suggests that the lunar surface gets rechurned faster than previously thought, which could force planetary scientists to adjust their solar system aging system that is based on crater counts.
The article makes the entirely false claim that this increased rate of impacts poses a threat to lunar colonies, probably in an effort by these scientists to lobby for funds for a combined lunar orbiter-lander mission. The first lunar colonies will likely be placed below ground, partly to protect them from the harsh lunar environment as well as from radiation, and partly because that will be the easiest way to build those colonies. The impacts being measured here are all relatively small, and would not threaten these underground colonies.
More Proton delays
The Russian investigation into problems during the last Proton launch in June has caused them to once again push back the next launch from November until December 2016.
There are still no details or updates from that investigation, including any hint as to why the rocket’s second stage had problems.
