Bigelow advocates his space stations for lunar missions

11:08 am

The competition heats up: Robert Bigelow today advocated using his privately built inflatable space station modules as a tool for launching future American lunar missions.

Bigelow’s company is eager to put a space station depot in lunar orbit, from which such activities and others can be initiated, as well as support onboard research. “We do not have the technologies, and there is zero business case for Mars. We do have a business case for the moon. And that’s why the moon absolutely makes the best sense,” Bigelow said. “And we can do the lunar activities far sooner than we can with Mars, which stretches out to, NASA’s views are Mars may be in the 2040s.”

His “New Space” company, Bigelow Aerospace of Las Vegas, designs space habitats, including a fully self-contained space station with 330 cubic meters of living and working space, which he said is ready for a lower-Earth orbit or, in about three years given the expected advancements in rocketry, for lunar orbit.

The key statement above is the comparison between lunar missions and Mars missions, at this time. The Moon has the chance to be profitable in the near future. Mars does not. If you had money to invest (even if it is taxpayer dollars) which would you invest it in?

The winds of Mars

10:00 am

New data from Curiosity has confirmed that the winds of Mars have been the primary force shaping the red planet’s landscape for billions of years.

The new data suggests that Mount Sharp once filled Gale Crater, and it was the winds that eroded it away to create the impression that it is the crater’s central peak. Instead it appears that it is the crater’s original floor!

Below the fold is the video from the link showing a number of dust devils imaged by Curiosity.

This link provides a gif animation showing the surprisingly significant changes to the ripples in the sand dunes directly below Curiosity that take place in only one day. The changes are astonishing, and show that even though Mars’ atmosphere is far thinner than Earth’s, it is capable of moving things quickly across the Martian surface.

"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

The oldest fossils ever?

7:35 pm

Scientists think they have found the oldest fossils ever in Canada.

Scientists say they have found the world’s oldest fossils, thought to have formed between 3.77bn and 4.28bn years ago. Comprised of tiny tubes and filaments made of an iron oxide known as haematite, the microfossils are believed to be the remains of bacteria that once thrived underwater around hydrothermal vents, relying on chemical reactions involving iron for their energy.

If correct, these fossils offer the oldest direct evidence for life on the planet. And that, the study’s authors say, offers insights into the origins of life on Earth. “If these rocks do indeed turn out to be 4.28 [bn years old] then we are talking about the origins of life developing very soon after the oceans formed 4.4bn years ago,” said Matthew Dodd, the first author of the research from University College, London.

This discovery reminds me of the Mars fossils discovered in the late 1990s. There were enormous uncertainties with that discovery, all of which eventually caused most scientists in the field to reject the result. The same thing could be the case here.

Still in Dallas. I hope to get caught up tomorrow.

China considering multi-asteroid mission

7:16 pm

The competition heats up: China is considering an unmanned probe to visit three different asteroids, including Apophis.

According to details that have previously emerged, one proposal is for a launch via Long March 3B rocket to take place in early 2022, with rendezvous with Apophis a year later and spend 220 days in orbit.

Then the probe would depart Apophis for a flyby of 2002 EX11 in 2025, and finally landing on 1996 FG3 in 2027, where it would, in Ji’s words, “conduct in-situ sampling analysis on the surface”.

The proposal is only in the design stage, but it should definitely be taken seriously. China is committing more and more of its resources to its space program, as that program is giving that government a big payoff in international recognition.

Posted in the airport in Dallas, where I have to wait an extra three hours because American Airlines practically shut the door to my connecting flight in my face. Their flight from Belize was late, and then Customs and the TSA conspired to create giant lines for no reason. Even though I had a friend at the gate with whom we were in contact by text who could tell them I was only a minute away, they shut the door anyway.

I have avoided American for more than a decade because they did something as obnoxious to me before. I think it might be a decade before I fly them again.

Conscious Choice cover

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.

Heading Home

10:22 pm

Today we completed our last caving trip in Belize. I and many of the expedition’s participants head home tomorrow.

Because our cave trips take so much time, I have not had time to post anything these last few days. I will try to post tomorrow during my return home, but expect full posting to resume on Thursday.

Also, though I will comment then in greater length about SpaceX’s announcement on Monday that they plan on sending two tourists around the Moon by 2018, I want to note here that this announcement is clearly Elon Musk’s response to the effort by NASA to delay the launch of commercial crew because of so-called safety issues so that SLS/Orion might fly first. Musk is telling the world that NASA’s safety concerns are crap (to which I generally agree) and he intends to prove this with his own lunar manned mission.

New auto-destruct system to increase launch rate

7:12 am

The competition heats up: A new auto-destruct system operating by computer, using GPS, and installed on each rocket should allow the launch rate in Florida to ramp up significantly.

Up until now it took several days to reconfigure the ground-based radar facilities. This system, first used on the most recent Falcon 9 launch, does not require this. It also involves fewer people to operate it. They expect that they will soon be able to launch up to 48 missions per year, some on the same day.

Sorry for the lack of posting on Friday. And it will be the same on Saturday. We have been underground all day surveying a cave, and will be doing it tomorrow as well. I should have time Sunday night to catch up.

Meanwhile, thanks to all the people who have generously donated or subscribed to Behind the Black. I am forever grateful for your support.

The life of Robert Mitchum

6:01 pm

An evening pause: While a little long for an evening pause, this half-hour documentary does a nice job of telling the surprisingly normal story of actor Robert Mitchum. What struck me most about it was how ordinary Mitchum’s life was. I’ve also seen the same thing with almost every Apollo astronaut that I have interviewed. Like most very famous people from the mid-twentieth century, they do not see themselves as particularly special. In fact, they led life with a certain humbleness, something that is hard to find today, especially among modern actors.

India’s government a barrier to private space

8:47 pm

Even as India and its space agency show themselves to increasingly be a major player in the worldwide aerospace market, it appears that India’s governmental policy on private satellite communications is acting as a barrier that blocks the growth of a commercial space industry.

India’s current satcom policy, first rolled out in 1997 and then updated in 2000, is clearly outdated. A senior ISRO official who attended the ORF event (but declined to be identified) pointed out that all the existing satcom policy says is Indian satellite companies will be given preference over foreign multinational companies. “How does this preference play out? If the department of space is worried about national security concerns, they should lay down clear guidelines for security compliance by foreign satellites. The existing policy doesn’t talk about this, which inevitably leaves it to ISRO, DoS and Antrix’s discretion,” the official told The Wire.

And this discretion has held up multiple applications for satellite manufacturing and foreign direct investment over the last decade. Hughes’ Krishna is particularly frustrated over this. “If a company submits an application for satellite broadband services in India, irrespective of where the satellites will be made, it needs a specific timeline on when it will hear back from ISRO or the DoS. Will it be two years, three years or five years? It is difficult to line up future investments if speedy clearance is not given,” Krishna said.

Essentially, India’s Department of Space (DoS) and its space agency ISRO control all licensing, and have been using that power to delay or deny the issuing of any private satellite licenses, since such efforts are in competition with these government agencies.

The situation here is very similar to what existed in the U.S. with NASA for most of the last half of the 20th century. The agency did not want private launch companies competing with its own manned programs, and diligently worked to block their efforts. If you wanted to be part of manned space, you did what NASA told you to do and you built what they told you to build. It wasn’t until the rise of the commercial space programs to launch cargo to ISS that NASA’s grip on manned space was finally broken.

India now faces the same problem. ISRO has done an excellent job, as NASA did in its early years, in getting India’s space industry started. It now needs to back off, stop running things and simply be a customer of these competing private companies, letting freedom do the job instead of government dictate. The question now is whether the Indian government will allow this to happen. There are many vested interests there that will resist.

Dragon safely berths at ISS one day late

8:12 pm

As expected, SpaceX’s Dragon freighter safely berthed at ISS today, one day late.

French astronaut Thomas Pesquet steered a 58-foot robotic arm to snare the unmanned Dragon at 5:44 a.m. EST, as the two spacecraft flew 250 miles above northwestern Australia. “Looks like we got a great capture,” radioed Shane Kimbrough, commander of the six-person Expedition 50 crew, to flight controllers in Houston.

The freighter will remain docked at ISS for a month while they off load it and load it with experiments being sent home.

NASA signs technology development contracts with eight companies

10:23 pm

The competition heats up: NASA today announced the award of contracts to eight small companies to develop new technologies for the advancement of smallsat launch capabilities.

The contracts cover a wide range of launch concepts, from testing new imaging technology for spotting asteroids to new rocket engine development to new rocket designs. The key component however of all these contracts is this:

These fixed-priced contracts include milestone payments tied to technical progress and require a minimum 25 percent industry contribution, though all awards are contingent on the availability of appropriated funding. The contracts are worth a combined total of approximately $17 million, and each have an approximate two-year performance period culminating in a small spacecraft orbital demonstration mission or the maturation of small launch vehicle technologies.

In other words, the companies have to provide some of the funding, since the technology being developed will benefit them. They also will only be paid once they meet certain milestones, and any cost overages will be their responsibility. The result? The U.S. has the chance of giving birth to eight new space companies, all with cutting edge technology that can compete in the new launch market. And the country gets this for a measly $17 million.

Aerojet Rocketdyne sets record testing new rocket engine

10:06 pm

The competition heats up: In recent static fire tests of its new AR-1 rocket engine Aerojet Rocketdyne set a record for the highest chamber pressure for any American engine using oxygen and kerosene.

They hope to convince ULA to use this engine in its Atlas 5 rocket to replace the Russian engine they presently use. At the moment, though ULA has made no commitment, it appears however that the company is favoring Blue Origin’s engine instead. That Congress favors Aerojet Rocketdyne is their one ace in the hole, since Congress controls the purse strings.

A solar system of exoEarths!

1:53 pm

Astronomers have discovered a nearby solar system of exoplanets, all approximately Earth-sized with at least three in the habitable.

Following these initial findings, the star was systematically monitored to find out whether it contained any other planets. The result of this follow-up exceeded all expectations: TRAPPIST-1 has at least seven planets, all of which are Earth-sized (to within 15%). The six nearest planets (b to g) orbit their star in 1.5 to 12 days (the period of the seventh planet remains to be determined), and are 20 to 90 times closer to their star than the distance from the Earth to the Sun. At such distances, the tidal forces exerted by the star are considerable, locking the planets into synchronous rotation, which means that they rotate about their axis exactly once in one orbit, thus always showing the same face to their star (just as the Moon does relative to the Earth).

The planets of TRAPPIST-1 have insolations, and therefore average temperatures, similar to Earth’s: the insolation of the innermost planet (b) is slightly higher than that of Mercury, while the outermost planets (g and h) have an insolation that is a little lower than that of Mars. The insolations of at least three of the planets (e, f and g) are compatible with the existence of liquid water on their surface for a wide range of atmospheric compositions, as is shown by numerical simulations of their climate. Due to their synchronous rotation, it cannot be excluded that the planets with the highest irradiation (b, c and d) may harbor liquid water in temperate regions with little or no sunlight.

More here. The star, a cool dwarf, is only 40 light years away.

Sea Launch deal finalized?

1:29 pm

The competition heats up? Two articles today in the Russia press suggest that either their settlement deal with Boeing over bankrupt Sea Launch is either on the verge of signing or the Russians are trying to pressure Boeing to an agreement by use of the press.

The first article says that a final agreement is about to be signed, but provides no date or indication from Boeing that they have agreed to terms. The second announces that the private Russian company that is acquiring Sea Launch from the Russian government to compete in the commercial launch market has been given a launch license by the Russian government, and will launch its first rocket from Baikonur later this year, using the Ukrainian Zenit-M rocket that was designed to fly from the Sea Launch floating platform. .This launch is intended as a test flight prior to restarting launches from the Sea Launch platform itself.

The complexity of this Sea Launch situation boggles my mind. Russia has sold Sea Launch to a private Russian airline company, S7, which will use a Ukrainian rocket to launch satellites from the Sea Launch platform. Before that can happen however Russia has to settle its dispute with Boeing, which won a $300+ million settlement in court over the breakup of their Sea Launch partnership. That settlement reportedly includes free passenger seats on Soyuz flights to ISS, which Boeing is reportedly offering to sell to NASA, which might need them. Meanwhile, Russia does not seem to have a problem with a Russian company using a Ukrainian rocket, even though Russia itself has completely banned the use of Ukrainian equipment on any of its own space rockets or capsules.

The business of commercial space sometimes amazes me.

Dragon aborts berthing with ISS

10:36 am

Because the spacecraft had apparently rendezvoused with ISS about 15 minutes early today, the computers on Dragon aborted the berthing, backing off to try again tomorrow.

No explanation as to why the spacecraft arrived so much earlier than expected, though it is reported to be in excellent shape.

Last Soyuz-U launches Progress to ISS

10:25 am

Russia today successfully launched a Progress freighter to ISS using its last Soyuz-U rocket.

The Soyuz-U has been launched hundreds of times since the 1970s, but has been replaced by Russia because it uses equipment made in Ukraine. The newer versions of the Soyuz rockets are completely home-built, but also have been plagued by quality control problems and corruption within Russia.

Off to Belize

5:01 am

Today, Wednesday, I head to the airport to return to the western regions of Belize for a week of cave exploration and mapping. Last time I was there in May we began a cave survey. I am now the cartographer for this project, and this time I hope we can finish it.

I intend to post while in Belize, though it will likely have to wait until each evening when we get back from the caves. I also intend to do my Batchelor appearances, but this time live from Mayan Mountain Lodge in San Ignacio, where we will be staying. The lodge was gracious enough in May to let me use their office and phone, and I expect they will be agreeable again this time.

Anyway, off for more adventure. The world is much too fascinating a place to see it just from my desk by way of the internet. You have to get out and see it for real whenever you can!

Scientists propose new planet definition that reinstates Pluto

6:03 pm

Unhappy since 2006 with the definition of “planet” imposed by the International Astronomical Union (IAU) that demoted Pluto, planetary scientists, including New Horizons principal investigator Alan Stern, have now proposed a new definition that they think is more appropriate and would reinstate Pluto.

The scientists suggest planets should constitute as “round objects in space that are smaller than stars,” thus excluding white dwarfs, neutron stars, and black holes from the planetary status. “A planet is a sub-stellar mass body that has never undergone nuclear fusion and that has sufficient self-gravitation to assume a spheroidal shape adequately described by a triaxial ellipsoid regardless of its orbital parameters,” the proposal elaborates, noting that the Earth’s moon would constitute as a planet under the new definition.

Stern and his colleagues note that the IAU’s definition of a planet is too narrow and recognizes planets only as objects that orbit our sun and “requires zone clearing, which no planet in our solar system can satisfy since new small bodies are constantly injected into planet-crossing orbits.”

Make sense to me as well as a lot of people. The definition created in 2006 was never very satisfactory, and I know many planetary scientists who have never accepted it.

Pan Am Boeing 707 – 1965 Emergency Landing

6:01 pm

An evening pause: This television news report about a 1965 near disaster where a Pan American passenger jet’s engine and wing fall off and the captain brings everything down safely is fascinating to watch, partly because of the live action footage taken by one passenger, but also at how television news has evolved since then, for the worse. This 1965 report has no shots a newsperson standing in front of the camera telling us what happened, as is typical today. Instead, the filming focuses on the events and the witnesses themselves, and lets them tell the story in as straight-forward a manner as possible.

Testing of Virgin Galactic’s LauncherOne first stage engine

5:56 pm

The competition heats up: This week Virgin Galactic’s successfully completed a long duration static fire test of the first stage engine of its LauncherOne smallsat rocket.

I predict that LauncherOne will fly its first commercial flight before Unity, the company’s second SpaceShipTwo spacecraft, and it will do it multiple times. In fact, right now I firmly believe that Unity is never going to reach suborbital space, as they have designed it for an engine that simply doesn’t work, and can’t figure out how to redesign it to solve the problem.

LauncherOne meanwhile has at least one launch contract, and is being designed with a workable engine, right from the start.
