First unmanned test flight of manned Dragon now set for Feb 9

10:01 am

Capitalism in space: SpaceX’s first unmanned test launch of its manned Dragon capsule, delayed repeated in recent months, has now been scheduled for no early than Feb 9, with its dress rehearsal countdown static fire test set for January 23.

It appears that this scheduled date is more firm than the previous ones, as it was announced as part of the upcoming schedule of the Eastern Range’s planning schedule.

The article provides some interesting details about the effect (or non-effect) the government shutdown on this launch. Bottom line: It should not prevent it, in the slightest. It must be repeatedly noted that the launch will use a SpaceX launch team on a SpaceX run launchpad, and will only require NASA participation during docking procedures, procedures that require NASA employees who have been deemed essential and thus are working (even if unpaid at the moment).

Is the pole of the Milky Way’s central black hole pointing directly at us?

9:42 am

The uncertainty of science: New data obtained using a constellation of Earth-based telescopes, working as a unit, strongly suggests that the pole of the Milky Way7s supermassive central black hole, dubbed Sagittarius A* (pronounced A-star), is pointing directly at us.

The high quality of the unscattered image has allowed the team to constrain theoretical models for the gas around Sgr A*. The bulk of the radio emission is coming from a mere 300 milllionth of a degree, and the source has a symmetrical morphology. “This may indicate that the radio emission is produced in a disk of infalling gas rather than by a radio jet,” explains Sara Issaoun, graduate student at the Radboud University Nijmegen in the Netherlands, who leads the work and has tested several computer models against the data. “However, that would make Sgr A* an exception compared to other radio emitting black holes. The alternative could be that the radio jet is pointing almost at us”.

The German astronomer Heino Falcke, Professor of Radio Astronomy at Radboud University and PhD supervisor of Issaoun, calls this statement very unusual, but he also no longer rules it out. Last year, Falcke would have considered this a contrived model, but recently the GRAVITY team came to a similar conclusion using ESO’s Very Large Telescope Interferometer of optical telescopes and an independent technique. “Maybe this is true after all”, concludes Falcke, “and we are looking at this beast from a very special vantage point.”

If this is true, it might explain why Sgr A* is generally observed to be one of the quietest central supermassive black holes known. Compared to many others, its flux of emissions is far less.

Democratic House threatens Webb cancellation

8:35 pm

The House, now controlled by the Democratic Party, has threatened cancellation of the James Webb Space Telescope should that project, already overbudget by $8 billion and 9 years behind schedule, fail to meet its present budget limits.

[The House budget] bill includes the full $304.6 million requested for JWST in 2019, but the report accompanying the bill offered harsh language, and a warning, regarding the space telescope given the cost overruns and schedule delays announced last year.

“There is profound disappointment with both NASA and its contractors regarding mismanagement, complete lack of careful oversight, and overall poor basic workmanship on JWST,” the report states. “NASA and its commercial partners seem to believe that congressional funding for this project and other development efforts is an entitlement, unaffected by failures to stay on schedule or within budget.”

The bill does increase the cost cap for JWST by about $800 million, to a little more than $8.8 billion, to address the latest overruns. “NASA should strictly adhere to this cap or, under this agreement, JWST will have to find cost savings or cancel the mission,” the report states.

I really don’t take this Congressional threat seriously. Our Congress is universally known in Washington as an easy mark for big money. The technique is called a buy-in, where you initially lowball the budget of your project, get it started, and then when it goes overbudget, Congress routinely shovels out the money to continue. Webb is a classic and maybe the worst example of this, but this game has been going on since the 1960s, with no sense that the Congresses of the last half century have had any problem with it.

And I especially don’t take it seriously from the Democrats who, even more than the Republicans, like to shovel money out.

The bankrupt unwillingness of both parties to care for the interest of the country for the past few decades in this matter explains why we have federal debt exceeding $20 trillion.

Ariane 6 might be in trouble

8:25 pm

Capitalism in space: Arianespace today announced that they will not be able to begin full production of their next generation rocket, Ariane 6, unless they get four more contracts from the partners in the European Space Agency.

With the maiden flight of the Ariane 6 now 18 months away (in July 2020), Arianespace CEO Stéphane Israël said the company had anticipated signing a manufacturing contract with ArianeGroup in the second part of last year to begin production beyond the first rocket.

So far, European public entities have purchased three Ariane 6 missions — two from the European Commission for launching Galileo navigation satellites, and one from France for the CSO-3 military imaging satellite — but have not committed to the number envisioned at the start of the Ariane 6 program in 2014.

“We are confident it will happen,” Israël said of the remaining government missions. “But it is not done yet. We are working in this direction. It is now quite urgent because industry has anticipated the manufacturing of these first launchers, but now we need these institutional contracts to fully contractualize the first Ariane 6s.”

I wonder if the fact that the cost for an Ariane 6 launch is expected to be remain higher than a comparable SpaceX launch is the reason they are having trouble getting a commitment from their European partners. Why buy this rocket, when you can get the same service for less?

Stratolaunch ends plan to build rockets for its giant Roc aircraft

8:14 pm

Capitalism in space: Stratolaunch has decided to cease work on the family of second stage rockets plus engine, announced in August and September 2018, that would have launched from the bottom of its giant Roc airplane.

Instead, they will only launch Northrop Grumman’s Pegasus rockets from Roc.

This does not look good for the company. Roc is vastly oversized for Pegasus, which really doesn’t need it. It also suggests that the death of Paul Allen has had a bad effect on the company.

ULA successfully launches U.S. spy satellite

7:47 pm

Capitalism in space: Using its Delta-4 Heavy rocket, the most powerful in its rocket family, ULA today successfully placed a National Reconnaissance Office (NRO) spy satellite into orbit.

It was also revealed in this article that ULA plans a total of seven launches in 2019, including today’s launch, the fewest in a year since ULA was formed in 2007 from a partnership of Boeing and Lockheed Martin.

The standings in the 2019 launch race:

1 China
1 SpaceX
1 Japan
1 ULA

The U.S. leads in the national standings 2 to 1 over China.

Scientists calculate length of Saturn’s day

6:58 pm

Using Cassini data of the rotation rate of Saturn’s rings, scientists have calculated what they think is the precise rotation rate of the planet itself.

Using new data from NASA’s Cassini spacecraft, researchers believe they have solved a longstanding mystery of solar system science: the length of a day on Saturn. It’s 10 hours, 33 minutes and 38 seconds. The figure has eluded planetary scientists for decades, because the gas giant has no solid surface with landmarks to track as it rotates, and it has an unusual magnetic field that hides the planet’s rotation rate.

The answer, it turned out, was hidden in the rings. During Cassini’s orbits of Saturn, instruments examined the icy, rocky rings in unprecedented detail. Christopher Mankovich, a graduate student in astronomy and astrophysics at UC Santa Cruz, used the data to study wave patterns within the rings. His work determined that the rings respond to vibrations within the planet itself, acting similarly to the seismometers used to measure movement caused by earthquakes. The interior of Saturn vibrates at frequencies that cause variations in its gravitational field. The rings, in turn, detect those movements in the field.

…Mankovich’s research, published Jan. 17 by Astrophysical Journal, describes how he developed models of Saturn’s internal structure that would match the rings’ waves. That allowed him to track the movements of the interior of the planet – and thus, its rotation. [emphasis mine]

This work certainly seems ingenious, clever, and somewhat convincing, but I must admit I laughed when I read their estimate of the day length above, to the second. That is ridiculous. Their margin of error cannot possibly be that small. Mankovich has for sure narrowed the uncertainty in the length of Saturn’s day, but forgive me if I remain skeptical as to the precision claimed.

Volcanic vent between Arsia and Pavonis Monsa

1:14 pm

volcanic vent on Mars

Cool image time. The photo on the right, rotated, cropped, and reduced to post here, was taken in September by the high resolution camera of Mars Reconnaissance Orbiter (MRO) and was part of the November image release. Click on the image to see the entire photograph at full resolution.

The uncaptioned release dubs this feature as “Small Eruptive Vents South of Pavonis Mons.” In truth, these vent pits are located almost exactly the same distance from both Pavonis Mons, the middle volcano in the line of three giant Martian volcanoes, and Arsia Mons, the southernmost of the three.

The image is interesting for several reasons. First, note the bulge surrounding the vent, making this look almost like a miniature volcano all its own. In fact, that is probably what it is. When it was active that bulge was likely caused by that activity, though it is hard to say whether the bulge was caused by flow coming from out of the vent, or by pressure from below pushing upward to cause the ground to rise. It could even have been a combination of both.

To my eye, most of the bulge was probably caused from pressure from below pushing upward. The edge of the bulge does not look like the leading edge of a lava flow. Still, this probably happened so long ago that Martian wind erosion and dust could have obscured that leading edge.

That this is old is indicated by the dunelike ripples inside the large pit, and the pond of trapped dust in the smaller pit. Because of the thinness of the Martian atmosphere it takes time to gather that much dust, during which time no eruptions have occurred.

One more interesting detail: If you look at the pits in full resolution, you will see that, based on the asymmetrical wind patterns between the west and east rims, the prevailing winds here are from the west. Located as it is just to the east of the gigantic saddle between Arsia and Pavonis Mons, this wind orientation makes sense, as a saddle between mountains tends to concentrate the wind, much like a narrowed section in a river produces faster water flow and rapids. As for why the wind blows mostly from the west, my guess (which should not be taken very seriously) is that it is probably caused by the same meteorological phenomenon that causes this generally on Earth, the planet’s rotation.

Bill to pay federal workers will not pay those not working

9:00 am

UPDATE: Thanks to my readers (see comments below), it appears that the essence of this story is wrong, and that the bill did provide for payment of salaries, even to those who did not work during the shutdown, essentially giving these federal employees a free paid vacation. What makes it even more galling is that federal workers generally are paid about twice what employees in the private sector get, and also get far better benefits, including vacation and sick time that is far far far longer. Now they get a cherry on top of that.

Some fiscal sanity enters Washington: The bill passed and signed this week by President Trump to pay federal workers will only provide pay to those who actually worked during the government shutdown.

While this might seem cruel to these workers, it is no different that the reality experienced by everyone in the private sector, and it is very fair to the taxpayers.

Astronomers begin their 2020 decadal survey

8:46 am

The astronomy community has begun work on their 2020 decadal survey, the report they issue at the start of every decade since the early 1960s outlining their space priorities for the upcoming ten years.

While the first four decadal surveys were very successful, leading to the surge in space telescopes in the 1990s, the last two surveys in 2000 and 2010 have been failures, with the former proposing the James Webb Space Telescope and the latter the Wide Field Infared Survey Telescope (WFIRST), both of which have not launched, are behind schedule, and significantly over-budget.

The new survey appears focused on addressing this.

The 2020 decadal survey will develop detailed cost estimates for each project, as well as guidance for what managers can do if money gets tight. “We have to look at the budget reality while also doing things that are visionary,” says Fiona Harrison, an astronomer at the California Institute of Technology in Pasadena and co-chair of the effort.

Unfortunately, it is also going to focus on leftist identity politics.

Responding to problems of racism and harassment in science, the survey will also assess the state of astronomy as a profession and make recommendations for how it can improve. “We’re going to go there,” says the other co-chair, Robert Kennicutt, an astronomer at the University of Arizona in Tucson and Texas A&M University in College Station.

I do not have high hopes for this decadal survey, or for space science in the 2020s. The space astronomy community chose badly in the past twenty years, and it is likely going to take another decade for it to recover. For example, WFIRST appears to be going forward, and it also appears that it will be the same financial black hole that Webb was, eating up the entire space astrophysics budget at NASA for years.

Smallsat rocket company Relativity Space gets Air Force okay to launch from Florida

8:29 am

Capitalism in space: The smallsat startup company Relativity Space has gotten Air Force approval to launch its 3D printed Terran rocket from Cape Canaveral.

They are now in negotiations to obtain a twenty year lease on one of the launchpads there.

Relativity hopes to sign a 20-year agreement granting it exclusive use of Launch Complex 16, a former Titan and Pershing missile site also used by NASA’s Gemini and Apollo programs. It was deactivated in 1988.

The company plans to spend more than $10 million to renovate the pad, build payload processing and integration hangars and install fuel and lightning protection systems.

It’s not yet known how many jobs will be based in Florida. The company has grown from 14 to 60 people over the past year, adding experience with a dozen former senior executives of existing Cape launchers SpaceX, Blue Origin and United Launch Alliance

The company has raised significant investment capital, $45 million, but there is no indication from the article when they plan their first test launches.

New local dust storm activity near silent Opportunity

8:19 am

The Opportunity science team reported today that they have noted an increase in local dust storm activity just south of the silent rover.

The storm is expected to increase in opacity (tau) at the rover site to greater than 1.5 over the next few days. No signal from Opportunity has been heard since Sol 5111 (June 10, 2018) during the historic global dust storm. Opportunity likely experienced a low-power fault, a mission clock fault and an up-loss timer fault. Since the loss of signal, the team has been listening for the rover over a broad range of times, frequencies and polarizations using the Deep Space Network (DSN) Radio Science Receiver.

This activity, plus the fact that they have still not been able to re-establish contact with the rover during the recent dust devil season, when they had hoped a devil might clear the dust off the solar panels, bodes very bad for the rover. The Curiosity team is also seeing more dust activity, and notes that these dust storms will also act to reduce the number of dust devils.

Congress and Trump give free paid vacation to federal workers during shutdown

10:05 am

The swamp wins: President Trump yesterday signed a Democratic Party bill guaranteeing the pay for all furloughed federal employees for the time they are either furloughed from work or working now without pay.

The signing of the Government Employee Fair Treatment Act of 2019, sponsored by Sen. Benjamin Cardin, D-Md., requires that all government employees be compensated for “wages lost, work performed, or leave used” during the shutdown, the Whitehouse announced in a news release.

Obviously, it seems just to pay for their time those who have been forced to work without pay. Why those who have not been needed are getting paid however seems very unjust, to the taxpayer. It would seem to me that they should not be paid for work they did not do. More apropos would be to consider removing them from the payroll permanently, as it appears based on this shutdown that most are likely unneeded to begin with.

SpaceX shifts some Starship/Super Heavy construction to Texas

9:03 am

Capitalism in space: SpaceX has decided to shift some of the construction of its new Starship/Super Heavy rocket from Los Angeles to its Boca Chica facility in Texas.

In tweets later Jan. 16, Elon Musk, the founder and chief executive of SpaceX, said that development of the vehicle itself, including the Raptor engines that power it, would continue in Hawthorne, while at least the prototype versions of Starship are built in Texas. “We are building the Starship prototypes locally at our launch site in Texas, as their size makes them very difficult to transport,” he said.

A shift to South Texas, industry sources said, could be a way to reduce expenses, given the lower cost of living there versus the Los Angeles area. However, that region of Texas has a much smaller workforce, particularly in aerospace, compared to Southern California.

Meanwhile, I keep hearing from my sources in the industry that SpaceX is facing more serious problems because of the coming decline in the manufacture of large geosynchronous satellites. The smallsat revolution appears to be the cause, and SpaceX’s larger rockets are not ideal for launching these tiny satellites. I am not entirely convinced of this pessimistic conclusion, but if SpaceX is in trouble it will likely be a tragedy for manned spaceflight. The smallsat rockets cannot put people in space. Neither can the gigantic government rockets like SLS. Without innovative companies like SpaceX building and launching large rockets for profit, the development of the large inexpensive rockets needed for human travel will be significantly hampered.

Fix pinpointed for Hubble main camera

8:54 am

Engineers have identified the issue that put the main camera of the Hubble Space Telescope into safe mode last week, and expect to have the camera back in operation in two or three days.

Hubble’s Wide Field Camera 3 (WFC3) took itself offline last week as a safety precaution, after onboard software noticed anomalous voltage readings within the instrument. But Hubble team members have now determined that voltage levels actually remained within the normal range, ascribing the glitch to a telemetry issue rather than a power-supply problem.

The mission team reset the relevant telemetry circuits, gathered some more engineering data and then brought the WFC3 back to an operational state. “All values were normal. Additional calibration and tests will be run over the next 48 to 72 hours to ensure that the instrument is operating properly,” NASA officials wrote in a Hubble update Tuesday (Jan. 15).

None of this changes the reality that it is almost a decade since the last shuttle repair mission, and Hubble is facing a long slow decline leading to its eventual loss, with no replacement planned by anyone.

Oregon & Washington politicians considering supervision of parents of all newborn babies

8:35 am

They’re coming for you next: The Democratic politicians in both Oregon and Washington are pushing new legislation that would mandate supervision by government health care workers of the parents of all newborn babies.

According to the Beaver Valley Times, “When the program is complete, every new parent — this includes adoptions — would receive a series of two or three visits by someone like a nurse or other health care practitioner. The visits could include basic health screenings for babies; hooking parents up with primary care physicians; linking them to other services; and coordinating the myriad childhood immunizations that babies need.”

The program has been piloted in Lincoln County but has not been tried statewide.

Sen. Elizabeth Steiner Hayward (D-Beaverton), who sits on the powerful Ways and Means Committee that will hammer out the language of the legislation, has said that universal home visits are a priority for her.

And Oregon is not alone in the push for “universal” home visits. Washington Governor Jay Inslee tweeted earlier this month, “My budget would also offer universal home visits. This gives every new parent the opportunity to get a visit from a nurse during the first few weeks back home with their newborn to share important information and build confidence.”

While it’s not clear whether either of these programs would be mandatory, the use of the term “universal” suggests that they would. It’s frightening to think about what would happen to parents who refuse such visits.

Read it all. It is obvious to both the author and I that while the present programs are vague about their mandatory nature, the goal is that they will soon become so.

Boston mayor wants doctors to grill patients about guns

9:52 am

They’re coming for you next: Boston’s liberal mayor want to require doctors to ask patients if they own guns and then lecture them about gun safety.

This act would require medical professionals to ask patients about guns in the home, and bring up the topics of gun safety. The goal, Boston Police Commissioner William Gross said, is to identify those at risk for domestic violence, suicide or child access to guns in order to guide people to mental health counseling, resources or other help. “We’re just asking them to help identify ways to save lives,” Gross said.

The fact that a patient owns guns would not be put in their medical record, and is not intended to have physicians help solve crimes.

If my doctor asked me this, I would tell him to jump in a lake. It is none of his business. However, this is clearly aimed at raising the social cost of gun ownership by making society more hostile to it. The next step would be to demand this data be recorded, which would then provide the government a list of gun owners that they can target.

Summer has finally arrived on Titan’s northern hemisphere

9:42 am

The uncertainty of science: In a review of Cassini data from 2016, scientists have finally identified rain in the northern polar regions of Titan, signaling the onset of summer there.

The whole Titan community has been looking forward to seeing clouds and rains on Titan’s north pole, indicating the start of the northern summer, but despite what the climate models had predicted, we weren’t even seeing any clouds,” said Rajani Dhingra, a doctoral student in physics at the University of Idaho in Moscow, and lead author of the new study accepted for publication in Geophysical Research Letters, a journal of the American Geophysical Union. “People called it the curious case of missing clouds.”

Dhingra and her colleagues identified a reflective feature near Titan’s north pole on an image taken June 7, 2016, by Cassini’s near-infrared instrument, the Visual and Infrared Mapping Spectrometer. The reflective feature covered approximately 46,332 square miles, roughly half the size of the Great Lakes, and did not appear on images from previous and subsequent Cassini passes.

Analyses of the short-term reflective feature suggested it likely resulted from sunlight reflecting off a wet surface. The study attributes the reflection to a methane rainfall event, followed by a probable period of evaporation. “It’s like looking at a sunlit wet sidewalk,” Dhingra said.

Though the data somewhat matches their climate models, those models did not predict the rain’s late arrival, which means they need revision. I guarantee that this will not be the last revision, though without an orbiter at Saturn it will probably be decades before we have new data to make that possible.

Shake-up at half billion dollar government ecology project

9:24 am

Even as the government shutdown continues, the contractor managing a $434 million ecology project has dismissed two project managers and dissolved a 20-member scientific advisory board.

The turmoil is the latest in a long line of woes for NEON, which launched in 2000 and has faced ballooning budgets and allegations of mismanagement by its previous operator. Battelle took over NEON’s operations in 2016 and, in 2018, appointed Collinge, an environmental scientist at the University of Colorado Boulder, as the network’s observatory director and chief scientist. The non-profit also created the 20-member Science, Technology & Education Advisory Committee (STEAC) to advise NEON.

STEAC members credit Battelle with saving NEON, and construction of its observatories is now on schedule. But several see the dismissals and cancellation of the board as a breach of trust with the scientists who hope to use NEON data. “That’s burning bridges, which you just can’t afford to do in a small community,” says Ankur Desai, an atmospheric scientist at the University of Wisconsin–Madison.

“I understand fully that this is very difficult and emotional for some people,” says Battelle spokesperson Patrick Jarvis. “Our goal remains to develop amazing data products and help the research community understand what’s going on at the broadest ecological level.”

The article includes a lot of whining by scientists about this, but I wonder. I also wonder at this project’s real scientific value. It could be legitimate, with the contractor merely cleaning house to make it run better. Or maybe it’s a boondoggle that is aimed solely at confirming the politically-driven environmental theories of the green activist community. If I had to guess, based on the track record of most big government projects these days, I’d pick the latter.

Argentinian smallsat company signs 90 satellite deal with China

9:14 am

An Argentinian smallsat company, Satellogic, has signed a 90 satellite launch deal with China.

Satellogic’s constellation seems likely to compete with the remote-imaging satellite constellations operated by San Francisco-based Planet and Seattle-based BlackSky. The company promises to remap Earth at 1-meter pixel resolution every week and dramatically reduce the cost of high-frequency geospatial analytics.

The deal is officially signed with a so-called private launch company in China dubbed China Great Wall Industry, but that company merely acts as an agent for a Chinese government space operation, China Aerospace Science and Technology Corp.

What this means however is that China’s launch rate is going to go even higher in the next few years.

A detailed look at the layoffs at SpaceX

9:07 am

Capitalism in space: Link here. Because of California’s complex employee protection laws, SpaceX has provided the government there a detailed list describing the 577 layoffs taking place in California.

Technicians — a critical role at any rocket company — make up the lion’s share of laid-off employees, with 174 positions eliminated (30.2% of all layoffs in Hawthorne). Engineers come next with 97 jobs let go, or nearly 17% of the locally terminated workforce.

Managers and supervisors together make up about 7% of the layoffs in Hawthorne. Positions listed under “Other” include baristas, dishwashers, drivers, recruiters, writers, and an investigator.

The article really doesn’t tell us much, other than the large majority of the 10% reduction are occurring in California, which makes me wonder if SpaceX is acting to reduce its presence in that high-tax, high-regulation state.

Arianespace plans at least 12 launches in 2019

8:59 am

Capitalism in space: The head of Arianespace today announced that it plans at least 12 launches in 2019.

Stéphane Israël, CEO of Evry, France-based Arianespace, said the company has four launches of the light-lift Vega rocket planned for this year, plus the maiden flight of the next-generation Vega C.

Arianespace’s first mission of the year is an Ariane 5 launch on Feb. 5. The rocket will carry two satellites — Arabsat’s Saudi GeoSat-1/Hellas Sat-4 and the Indian space agency ISRO’s GSAT-31 — to geostationary transfer orbit. All five Ariane 5 missions planned for this year will carry two satellites, as is customary, Israël said in an interview.

Israël said Arianespace has three firm Soyuz launches on its 2019 manifest, starting mid-February with the launch of 10 small telecom satellites for internet megaconstellation startup OneWeb.

Israël actually lists thirteen launches here, so I am not sure why the article sets the number at twelve. This number is only two more than my initial estimate based on scheduled launches listed here.

Update on Chang’e-4 plant experiments

5:32 pm

Link here. It appears the plant experiment has now run its course, designed as it was to end before the arrival of the first lunar night.

The experiment’s chief designer, Xie Gengxin of Chongqing University, told Xinhua that life inside the canister would not survive the lander’s first lunar night, which started on Sunday. The moon’s nighttime period lasts for about two Earth weeks.

It also appears that though the plant experiment included potato, cotton, and oilseed rape, only the cotton seeds spouted. China has only released a limited amount of information about this research, so to get further details we will likely have to wait for the published papers.

More updates from SpaceX’s Boca Chica launch site

9:16 am

Link here. The article reviews what has been done for the past few months, as well as what has been done most recently. All of this new work appears focused on preparing for test flights of Starship and Super Heavy.

I should note however that I am beginning to sense a little bit of Barnum in this work. The steel-clad Starship Hopper that SpaceX has assembled here is clearly not even close to doing any hopper tests, as it doesn’t appear to have fuel tanks and its engines appear to be mere “placeholders for fit checks.” It looks really really cool, however, and is impossible to hide to the public, so it thus has garnered the company a lot of attention.

Seeds sprout on Chang’e-4

9:01 am

The new colonial movement: The cotten seeds in a plant experiment on Chang’e-4 have now sprouted, becoming the first biological life to grow on the Moon.

On Tuesday, Chinese state media said the cotton seeds had now grown buds. The ruling Communist Party’s official mouthpiece the People’s Daily tweeted an image of the sprouted seed, saying it marked “the completion of humankind’s first biological experiment on the Moon”.

Fred Watson, Australian Astronomical Observatory’s astronomer-at-large, told the BBC the development was “good news”. “It suggests that there might not be insurmountable problems for astronauts in future trying to grow their own crops on the moon in a controlled environment. …I think there’s certainly a great deal of interest in using the Moon as staging post, particularly for flights to Mars, because it’s relatively near the Earth,” Mr Watson said.

Prof Xie Gengxin, the experiment’s chief designer, was quoted as saying in the South China Morning Post: “We have given consideration to future survival in space. Learning about these plants’ growth in a low-gravity environment would allow us to lay the foundation for our future establishment of space base.” He said cotton could eventually be used for clothing while the potatoes could be a food source for astronauts and the rapeseed for oil.

This experiment is actually a very big deal, as it is the first biological experiment, ever, to take place in a low gravity environment. All previous plant experiments in space have taken place in zero gravity, and thus failed to tell us anything about growth in a partial Earth gravity environment.

That the seeds have sprouted only tells us that they can. What we don’t know yet is if the low lunar gravity distorts their growth.

Iran rocket fails to place satellite in orbit

8:44 am

The new colonial movement: According to their government sources, Iran today tried and failed to place a Earth imaging satellite into orbit with their Simorgh rocket.

The rocket carrying the Payam satellite failed to reach the “necessary speed” in the third stage of its launch, Telecommunications Minister Mohammad Javad Azari Jahromi said.

Jahromi said the rocket had successfully passed its first and second stages before developing problems in the third. He didn’t elaborate on what caused the rocket failure but promised that Iranian scientists would continue their work.

I wonder how much of a failure this launch is. If they were testing an ICBM capability, then the successful operation of the first and second stages would likely rank this as a success. And even if their main goal wasn’t ICBM testing, in the end they have done so, as they can apply what they learn here to all military missile technology.

Update: You can see video of the launch at this Iranian press story, along with other details about Iran’s space effort. I found the comments there most educational however. Here’s one sample: “Iran needs to use its space technology to fire invincible hyper-sonic missiles from space at the Jews in Israel.” The comments are all not like this, but there are enough to give you a sense of Iran’s social culture.
