An evening pause: At first glance you might think this an April Fool’s piece, but it really isn’t. To be a good April Fool’s joke, you have to be fooled for at least a little while, something this does not do. What this video does do however is illustrate in an hilarious way the empty fake nature of television news. This is what they do normally, which has as much reality as this video.

Rather than have two more consecutive posts about SpaceX, I’ve decided to post these two together in an effort to avoid making this website look like a site totally devoted only to this one company.
The first story makes it clear that SpaceX will almost certainly fly the first unmanned demo missions of its manned capsule later this year. We should also get an idea whether the first manned flight will occur before the end of the year, or slip into 2019, in May.
The second story reveals once again the robust and growing financial value of SpaceX.
Elon Musk-led SpaceX Corp is raising $507 million in a new round of funding, valuing the company at around $26 billion, according to a filing seen by Reuters. New articles of incorporation filed by the company last week and sent to Reuters by private analytics firm Lagniappe Labs showed the addition of 3 million ‘Series I’ shares from a previous version filed in November.
The filing also gave the initial value of the Series I shares as $169, 25 percent higher than a value given in its previous fundraising round late last year.
As Al Jolson once said, “You ain’t seen nothin’ yet!” I expect that SpaceX’s value will only go up in the coming years.
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.
"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
Europe’s Mars Express orbiter has taken a high resolution image of Ismenia Patera, a very large crater located in the Arabia Terra region of Mars, the largest part of the transition zone between the low flat northern plains and the high rough southern terrain.
The crater is intriguing to scientists because they are not sure if it was created by an impact, or a volcano.
Certain properties of the surface features seen in Arabia Terra suggest a volcanic origin: for example, their irregular shapes, low topographic relief, their relatively uplifted rims and apparent lack of ejected material that would usually be present around an impact crater.
However, some of these features and irregular shapes could also be present in impact craters that have simply evolved and interacted with their environment in particular ways over time.
There is also additional evidence that this region was once home to volcanic activity. If so, that activity would have changed the terrain, and thus made its geological history more complex and difficult to decipher, a fact that is important since this is also a region that might have been at the edge of theorized northern Martian Ocean.
Link here. In requesting permission to recover Dragon capsules in the Gulf of Mexico, SpaceX submitted a great deal of information to the FAA about its effort to recover and reuse the fairings of its Falcon 9 rocket. Doug Messier of Parabolic Arc has done a nice job of excerpting that information at the link.
For example, SpaceX is not only trying to recover the fairings, it is trying to recover the new fairing drogue chutes that it uses to slow the fairings down and then ejects before splashdown.
To me, however, one tidbit that stood out like a beacon and actually tells us more about SpaceX’s future anticipated launch rate was this quote:
From 2019-2024, SpaceX anticipates the frequency of launches involving fairing recovery to increase. In 2018, SpaceX anticipates approximately two recovery attempts, and from 2019-2024, SpaceX anticipates approximately three recovery attempts per month. Thus, for all seven years, SpaceX anticipates up to 480 drogue parachutes and 480 parafoils would land in the ocean.
This is further confirmation of SpaceX’s public prediction that it will soon be launching about 30 to 40 times per year. These numbers also equal the best yearly rates the entire United States launch industry ever achieved, and suggest that the entire launch industry in the next decade will be experiencing a significant boom, since aggressive competition usually causes an increase in business for all competitors.

Researchers have devised a new much more efficient technique for removing carbon dioxide from the smoke of power plants.
The memzyme meets the Department of Energy’s standards by capturing 90 percent of power plant carbon dioxide production at a relatively low cost of $40 per ton. Researchers term the membrane a “memzyme” because it acts like a filter but is near-saturated with an enzyme, carbonic anhydrase, developed by living cells over millions of years to help rid themselves of carbon dioxide efficiently and rapidly.
“To date, stripping carbon dioxide from smoke has been prohibitively expensive using the thick, solid, polymer membranes currently available,” says Jeff Brinker, a Sandia fellow, University of New Mexico regents’ professor and the paper’s lead author. “Our inexpensive method follows nature’s lead in our use of a water-based membrane only 18 nanometers thick that incorporates natural enzymes to capture 90 percent of carbon dioxide released. (A nanometer is about 1/700 of the diameter of a human hair.) This is almost 70 percent better than current commercial methods, and it’s done at a fraction of the cost.”
The article also notes at the end that this technology could also be adapted to scrubbing CO2 from spacecraft atmospheres.

What could possibly go wrong? The Environmental Defense Fund (EDF), historically one of the U.S.’s most partisan and aggressive environmental activist groups, has announced that it has raised millions to build a satellite to measure atmospheric methane, with a launch aimed for 2020.
The EDF, which is based in New York City, aims to launch the satellite as early as 2020. The environmental group and its scientific partners at Harvard University and the Harvard-Smithsonian Center for Astrophysics in Cambridge, Massachusetts, say that their planned ‘MethaneSAT’ will make the most precise measurements of methane yet from space. Their goal is to monitor emissions from roughly 50 major oil and gas fields that account for around 80% of the world’s oil and gas production. But the satellite could also be used to estimate emissions from landfills and agriculture.
“We need good solid data so that we really can support global action on climate change, and we’ve got to do it fast,” says Steven Hamburg, the EDF’s chief scientist.
MethaneSAT is an offshoot of the EDF’s research on greenhouse-gas emissions from US oil and gas facilities. In 2012, the group spearheaded a collaboration with industry and academic scientists to better quantify methane emissions and identify leaky infrastructure, from the wellhead all the way to the urban distribution system. That work is ongoing, but suggests that methane emissions from oil and gas facilities exceed US government estimates. Last year, the EDF helped to launch another collaboration with industry partners, governments and academics to carry that research forward internationally. [emphasis mine]
While I applaud their effort to do real research, I have serious concerns about the objectivity of their work. It appears they are aiming this satellite to look specifically at oil and gas facilities, the big enemies of the global-warming community, and clearly wish to document evidence for human-caused global warming. Thus, it will not be surprising if their research results end up biased in these directions.
Nonetheless, this project’s funding, much of it from private sources, highlights the on-going shift away from government money for the funding of space missions, as did my previous post As noted at the link above,
The EDF declined to provide a precise cost estimate for its satellite because the design remains in flux, but said that it is likely to be in the tens of millions of dollars. The group is seeking extra support from philanthropists to operate the satellite once it’s in orbit. All the data will be freely available. Hamburg says that the project provides a new model for funding targeted space missions. “We’re going to be the first, but I think we’re going to see this approach be used by others as well,” he says.
Capitalism in space: A survey of the money raised in the first quarter of 2018 has found that commercial space has raised nearly $1 billion, all from non-government sources.
The April 10 report by Space Angels, a fund that invests in early-stage space companies, concluded that there was $975.8 million in non-government equity investment in space companies in the first quarter of 2018. That would put the industry on a pace for nearly $4 billion for the year, a figure similar to the estimate made by Space Angels for investment in the industry in 2017.
Just over half of that total for the first quarter, though, came from a single investment identified by Space Angels: a $500 million investment in SpaceX led by Fidelity Investments. That investment is intended “to drive development of their satellite communications network, Starlink,” the report stated.
It appears from the article that the bulk of the investment capital went, not to launch rocket projects, but to satellite proposals. Even so, those satellites will have to get launched, so investment in private rockets is sure to go up in the coming years.
Capitalism in space: A new smallsat rocket company, EXOS Aerospace Systems & Technologies, has announced that it will do a test launch out of Spaceport America on May 5, the anniversary of Alan Shepard’s first suborbital flight, of a rocket it dubs SARGE.
The press release did not specifically say whether the test launch would be suborbital or not, though I strongly suspect so. Nor can I find any details about this rocket or the launch at the company’s website. The company sells itself as building reusable rockets, and the press release includes a video of a hover static fire test of one rocket. Other videos at the company’s website show short clips of other flights were an earlier rocket returned to Earth by parachute. They state that SARGE is an upgrade, so maybe they are going to use its engines to slow the landing.
Either way, the smallsat launch industry is getting very crowded. This company seems right now aimed at capturing the suborbital science and school portion of the market that is looking for cheap quick ways to get payloads up into space for very short periods at very low cost.
The search for new exoplanets orbiting the three stars of the Alpha Centauri star system is intensifying, despite significant viewing challenges and solar activity that precludes life around one star.
The system’s two sunlike stars, Alpha Centauri A and B, orbit each other closely while Proxima Centauri, a tempestuous red dwarf, hangs onto the system tenuously in a much more distant orbit. In 2016, astronomers discovered an Earth-mass planet around Proxima Centauri, but the planet, blasted by radiation and fierce stellar winds, seems unlikely to be habitable. Astrobiologists think the other two stars are more likely to host temperate, Earth-like planets.
Maksym Lisogorskyi, an astronomer at the University of Hertfordshire in Hatfield, U.K., tried to find them with an instrument on the European Southern Observatory’s (ESO’s) 3.6-meter telescope in Chile. He and his colleagues looked for Doppler shifts in the spectral lines of the stars’ light that would be caused if a planet tugged them back and forth. But Lisogorskyi told the meeting that the stars’ surfaces are turbulent, and prone to flares that also jiggle the spectral lines, masking the subtle signals from any Earth-size planets. “The lines do all kinds of things,” he says. Although Alpha Centauri has been a primary target for the planet-finding instrument since it was inaugurated in 2005, it has seen nothing so far.
Also hampering observations are the current positions of the two stars. As viewed from Earth, they are very close together, making them harder to study individually, Lily Zhao of Yale University told the meeting. More precise observations should become possible as their 80-year orbit carries them farther apart. In the meantime, Zhao and her colleagues have succeeded in ruling out the presence of giant planets around either star, based on a decade’s worth of data from three instruments on different telescopes. “There are no Jupiters in the system, but there may be plenty of Earth-sized planets still to discover,” she said.
I am skeptical of the conclusions of the astrobiologists who think there may be habitable Earth-like planets in orbit around the close binary. Binary formation makes planetary formation difficult, and even if they are there the stars’ orbits would make stable orbits unlikely. Nonetheless, the research is good, as the techniques learned will be applicable elsewhere.
India’s PSLV rocket tonight successfully launched a replacement GPS satellite for its navigational system, replacing the satellite lost on a PSLV launch last year.
The leaders in the 2018 launch standings:
11 China
7 SpaceX
3 Japan
3 Russia
3 ULA
3 Europe
3 India
It surely is getting crowded near the bottom. It is also interesting that nations like India and Japan are still running neck and neck with Russia and Europe. Just last year their total launches didn’t match Europe’s, and was just a touch over half of Russia’s.
Update: News articles today say that, according to the head of ISRO, India is aiming for another 9 launches in 2018, for a total of 12, a new record for that country, while Russia’s space chief says they will complete 30 launches before the end of the year. I think India’s prediction is accurate, while Russia’s is hogwash.

An evening pause: There are two clips, with the second beginning at 4:37. This is I think more interesting than good. The first clip is well shot, but it clearly is an unfinished music video because Hendrix himself I think was unsatisfied with his performance. The second is better performed, as it is a improvised performance at what appears to be a party. Regardless, they are worth watching because even when he played below par you can see he is playing at a level above most.

A company is now marketing to the military a jamming devise, designed like a gun, that acts to shut down all commercially-made drones.
the gun is as simple as point-and-shoot, with a 30 degree cone of effect on whatever target is being aimed at. And a newer version of the device is even attachable to an assault rifle, similar to how one would attach an M203 grenade launcher. “You point in that direction, and when the drone flies into the cone … the cheaper drones would just crash. But the better ones will fly back to base,” he added. “It can also track the drone and follow it back to home and see who was actually flying it.”
The jammer, which really isn’t a gun, is aimed at disarming the commercial drones used in the Middle East by the radical Islamic fighters, who don’t have the technology to build their own more sophisticated weapons. Sadly, I can see a time in the future where ordinary citizens might want one too.
The satire site the Babylon Bee has been hitting home runs all week with a series of posts poking fun at Facebook’s founder Mark Zuckerberg in connection with his appearance this week at a Senate hearing.
From the last story:
Passing a set of tablets around the room, the tech billionaire asked every person present to read and accept the full 335,000-word, 6-point-font document before they could proceed. “If you would please just click the button signing all of your personal data over to me, yada yada yada, we can get this show on the road,” Zuckerberg said calmly before taking a sip of water. “It’s your basic, no-frills TOS. Nothing to worry about in there, I promise.”
The congressmen quickly skimmed the first of the 1,342 digital pages before clicking “accept” as per their customary approach to signing important legislation as part of their daily jobs, according to sources present.
We must remember that Facebook had previously tried to censor the Bee for publishing “fake news,” and the Bee has clearly not forgiven them for it.
The Juno science team has released an animation that shows, in infrared and in three dimensions, the storms of Jupiter’s north pole.
The link has three videos. One shows the gas giant’s surprisingly irregular magnetic field, as found by Juno. The first and third show a low and a high fly-over of the north pole, in infrared. I have embedded both fly-overs below the fold. First watch the high fly-over, which is the first video. This will make the low fly-over more understandable as it flies over the eight smaller storms that encircle the pole’s central vortex.

Capitalism in space: NanoRacks, which already makes money launching private payloads to ISS, has revealed its plans for building its own private space station using converted Atlas 5 upper stages.
This project was previously called Ixion, but they have dropped that name, and will now call the first station Independence-1.
They have a contract with NASA for the initial development, and hope to convince the agency to pay them to next build a full-size test prototype. The video at the link to me was exceedingly unconvincing however. It shows a robot beginning the process of refurbishing a used upper stage while in orbit, and simplifies the process to an almost ludicrous degree. While I surely believe it can be done, it will not be simple. The difficulties should not be dismissed.

Fascist New York: A Hawaiian man is going to jail for two years, simply because he mistakenly brought a legally purchased gun into New York City, locked safely in his car.
Officers interviewed Camp’s girlfriend who told them, out of spite, he says, about a weapon he had in his car. In a small compartment behind the seat of his ’85 Chevrolet El Camino, Camp stored a Hi-point .45 pistol he bought legally in Ohio for $140 and that he kept locked away in a safe. When the officers found the weapon, Camp was arrested and charged with a Class C Felony.
His girlfriend had a far-left stance on guns. She said it frightened her to have one in their apartment and so Camp kept it locked safely away in the car to appease her, he explained.
Even his former girlfriend didn’t realize the draconian nature of New York’s gun laws. “I’ve never used it to menace or threaten anyone, especially not her,” Camp said. “She even later told me she regretted turning me in to the police, saying she believed I would ‘just pay a big fine.’”
No matter. New York City does not recognize the second amendment of the Bill of Rights. You do not have the right to bear arms there, even though the threat of gun violence from criminals is far higher than most of the rest of the country.
Note the absurdity of this. New York’s draconian gun control laws were supposedly passed to prevent criminals from getting guns. Instead, they are being used to jail innocent citizens whose only reason for owning a gun is to protect themselves from those illegally armed criminals.
