New method for scrubbing CO2 out of the air

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.

Environmental activists to build methane-detecting satellite

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.

Private space raised nearly $1 billion the first quarter of 2018

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.

Another smallsat rocket company enters the fray

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.

Jimi Hendrix On An Acoustic Guitar

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 gun to shoot down drones

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.

NanoRacks outlines its private space station plans

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.

Two investigations blame Northrop Grumman for Zuma failure

Two independent investigations have now placed the blame for the failure of the classified Zuma satellite to reach orbit on Northrop Grumman, not SpaceX.

Two independent investigations, made up of federal and industry officials, pointed to Northrop’s payload adapter as the cause of the satellite’s loss, the report said, citing people familiar with the probes. The payload adapter is a key part of deploying a satellite in orbit, connecting the satellite to the upper stage of a rocket.

…The investigations tentatively concluded that onboard sensors did not immediately communicate to ground systems that the satellite did not separate from the rocket, according to the Journal. Unbeknownst to officials at the time, the planned return of the rocket’s upper stage — a method of disposal to avoid adding space debris around the Earth — brought the satellite back down with it. By the time the satellite separated from the rocket it was too late, putting Zuma too low in orbit to save, according to the report.

I still have a nagging suspicion that Zuma actually did reach orbit, and this entire story that it never separated from the upper stage is all a disinformation campaign to help distract people from the satellite’s existence in orbit. At the same time, by this time I don’t put much faith in my own suspicions. These two reports appear to settle the matter.

NASA expands first manned Starliner mission

NASA has modified its contract with Boeing to allow its first manned Starliner test mission to add an astronaut and extend the mission’s length so that it more resembles an operational flight to ISS.

NASA is considering adding a third crew member to the Starliner’s “Crew Flight Test” and could extend its trip to the International Space Station from two weeks up to six months, the length of a typical ISS expedition. The potential changes, outlined in a contract modification with Boeing, could help NASA maintain its presence on the International Space Station through 2019 and beyond.

NASA’s last purchased ride aboard a Russian Soyuz spacecraft, upon which the U.S. has relied for access to the ISS since the shuttle’s retirement in 2011, is scheduled to launch in the fall of 2019.
Boeing’s new Starliner spacesuit features lightweight fabric, slim gloves and sneaker-like boots. But Boeing’s Starliner and SpaceX’s Crew Dragon may not be certified to fly four-person crews until after that. “This contract modification provides NASA with additional schedule margin if needed,” said Bill Gerstenmaier, head of human spaceflight operations at NASA headquarters in Washington. “We appreciate Boeing’s willingness to evolve its flight to ensure we have continued access to space for our astronauts.”

Doing this makes some sense, but I wonder why NASA chose to do it with Boeing’s Starliner instead of SpaceX’s Dragon. Starliner has never flown in any form, while the manned Dragon is based on SpaceX’s well tested design.

I suspect NASA will soon modify its SpaceX contract as well. It makes sense. Once you put humans on board, you might as well give yourself the option to do a full mission.

First SpaceshipTwo powered flight since accident

Capitalism in space? Virgin Galactic today successfully completed the first powered test flight of VSS Unity, the first such test flight since the flight accident that destroyed the first SpaceShipTwo and killed on pilot in October 2014.

VSS Unity was dropped from its WhiteKnightTwo mothership from about 50,000 feet (15,000 meters) over the mountains about 20 miles (32 kilometers) north of the Mojave Air and Space Port in California. Pilots David Mackay and Mark “Forger” Stucky fired Unity’s hybrid engine for 30 seconds, boosting the vehicle to a top speed of Mach 1.87 and a maximum altitude of 84,271 feet (25,686 m) before gliding back to the runway at the spaceport, Virgin Galactic representatives said.

During the descent, the crew deployed SpaceShipTwo’s feather system, which reconfigures the ship into a high-drag shuttlecock by moving its twin tail booms. The feather will be used to soften the vehicle’s re-entry into the Earth’s atmosphere during spaceflight.

They say that they hope to begin commercial flights later this year, but I remain exceedingly skeptical.

Another space station hotel company enters the market

Capitalism in space: A new space station hotel start-up, Orion Span, hopes to launch their first module by 2021, and begin accommodating guests by 2022.

Aurora Station will accommodate four paying guests and two crewmembers; these latter personnel will likely be former astronauts, Bunger said. Most of the guests will probably be private space tourists, at least initially, but Orion Span will be available to a variety of customers, including government space agencies, he added.

And the space hotel will get bigger over time, if everything goes according to plan. As demand grows, Orion Span will launch additional modules to link up with the original core outpost, Bunger said. “Our long-term vision is to sell actual space in those new modules,” he said. “We’re calling that a space condo. So, either for living or subleasing, that’s the future vision here — to create a long-term, sustainable human habitation in LEO [low Earth orbit].”

This makes three companies vying to build the first private space stations, with Bigelow and Axiom Space already in the game.

Revisiting Biosphere 2

Biosphere 2

This week Diane and I have a friend visiting from back east. As locals generally do when guests visit, we used this visit as an excuse to go sightseeing at local attractions that we somehow never got the time to visit on our own.

So on Tuesday we drove north to take a tour of Biosphere 2, what has been called “a giant space-age ark in the middle of the desert.” The idea, as sold heavily to the public when it was built in the late 1980s and early 1990s, was that eight people would try to live in a closed system for two years, demonstrating the technology needed to both build colonies on other worlds as well as protect the environment here on Earth.

The system wasn’t really closed however (power came from outside), and during the first two year mission it seemed they were somewhat lax about keeping the system closed.

One Biospherian accidentally cut off the tip of her finger and left for medical care. When she returned, she carried in two duffle bags of supplies to the supposedly self-sustaining environment (which presumably would not have been feasible on, say, Mars).

There were also financial issues, as mentioned by our tour guide and confirmed by news stories. Its backer, Texas oil man Edward Bass, spent somewhere between $150 to $200 million. It seems however that the managers running Biosphere 2 didn’t keep good books, and when Bass asked for an accounting they couldn’t provide it. Instead, they attempted to sabotage the project’s second mission.

Rocket Lab next launch window opens April 20

Capitalism in space: Rocket Lab today announced that the first official operational launch of its Electron rocket will take place in a window beginning April 20.

If this launch is successful, expect the company to begin to ramp up its launch pace. Their goal is to have the ability to launch once every three days, which will also give them the ability to quickly schedule payloads at a moment’s notice.

SpaceX launches Dragon to ISS

SpaceX successfully launched a reused Dragon capsule into orbit yesterday, once again using a reused first stage.

To show you how routine this has become, I myself completely forgot the launch was happening yesterday, and spent that time doing my monthly bills. Oy.

They did not attempt to recover the first stage, using it instead to do re-entry flight tests as it landed in the Atlantic Ocean. I suspect they have decided that it is not cost effective to recover used first stages, and would rather dump them in the ocean than pay the cost to recover, test, and store them.

The leaders in the 2018 launch standings:

10 China
7 SpaceX
4 Russia
3 Japan
3 ULA

China and the U.S. continue to be tied in the national standings.

SpaceX ship returns with this week’s fairing apparently intact

Despite tweets from Elon Musk suggesting it had hit the water at “high speed,” SpaceX’s recovery ship appears to have returned with one half of the fairing intact.

There are several images at the link showing the fairing on the ship. That it recovered it out of the water without damage seems surprising and unlikely. Nonetheless, that it looks intact means that the parafoil managed to slow it down enough to limit damage as it hit the water, and the company seems to be making real progress towards making these fairings reusable.

A detailed look at Orbital ATK’s Next Generation Launcher (NGL)

Link here. Based on the solid rocket technology developed for the shuttle and then for Ares, they hope to make the first launch in 2021, and actually do two flights that year to get certified by the Air Force so that they can bid on military launch contracts.

Development money for this rocket has come mostly from the Air Force, not from private funds raised by Orbital ATK. It also seems to me that it has taken far longer to get it built than it should if they really wanted to get a rocket up and running to compete for business. Moreover, they expect the Air Force to certify them after only two launches, while it took SpaceX a lawsuit and far more launches to get the same certification.

Thus, all told there is a bit of crony capitalism involved here. NGL might turn out to be a good deal, in the long run, but forgive me if I reserve my opinion.

FCC approves SpaceX 4K+ satellite constellation with strict new requirements

Capitalism in space: The FCC today approved SpaceX proposed gigantic 4,425 Starlink satellite constellation, designed to provide internet access worldwide, while also imposing a deadline for its launch and requiring the company to provide detailed de-orbit plans.

SpaceX will have to launch at least half of its constellation of Ku- and Ka-band satellites within six years of today, per the agency’s recently revised rules, or its authorization freezes at the number of satellites in operation at that date. The FCC in September relaxed its deadline, giving operators nine years to launch their full constellation, but even those rules are stricter than what SpaceX would refer. The launch-provider-turned-satellite operator asked the FCC for an okay to launch 1,600 satellites in six years — just over a third of its full constellation.

SpaceX said the FCC’s deadline was “impractical” and that it could start broadband service without the full constellation. The FCC said no, but gave SpaceX permission to re-submit a waiver request in the future. SpaceX said in October it plans to start service with 800 to 900 satellites.

SpaceX’s constellation is the largest of all the applicants, generating concern about its potential to enshroud the Earth in a cloud of space debris. Fleet operators OneWeb, Spire, SES and Space Norway all expressed concern about how SpaceX will protect the space environment when operating so many satellites. But weighing more heavily with the FCC was NASA, which said a constellation as large as SpaceX’s likely needs to meet more stringent standards than what NASA recommends for de-orbit reliability. NASA’s reliability standard is that at least 90 percent of satellites can deorbit properly after their mission is complete.

The FCC did say that SpaceX will have the right in the future to request a waiver on the launch deadline.

Blue Origin changes engines for New Glenn second stage

Capitalism in space: In order to maintain its goal of launch its orbital New Glenn rocket by 2020, Blue Origin has changed the engine it will use in the rocket’s second stage from a version of its main BE-4 engine to new version of their already developed BE-3 engine, used in their reusable New Shepard suborbital spacecraft.

A Blue Origin executive told SpaceNews the company is shelving development of a vacuum-optimized version of BE-4 and will instead use vacuum-optimized versions of flight-proven BE-3 engines for New Glenn’s second stage and optional third stage. “We’ve already flown BE-3s, and we were already in the development program for BE-3U as the third stage for New Glenn,” said Clay Mowry, Blue Origin’s vice president of sales, marketing and customer experience. “It made a lot of sense for us to switch to an architecture where we get there faster for first flight.”

The BE-3U is the upper stage variant of the liquid hydrogen-fueled BE-3 engine that has powered Blue Origin’s reusable New Shepard spacecraft on seven suborbital test flights since its 2015 debut. Mowry said switching to the BE-3U for New Glenn’s second stage will allow Blue Origin to conduct the rocket’s first launch in the fourth quarter of 2020. He declined to say how much time the engine change saves compared to the original configuration.

This quiet change, which the company made with no fanfare, carries with it some significant information as well as important ramifications. First, the BE-3 engine is less powerful than the planned BE-4, which is why they will use two BE-3 engines in the second stage instead of one BE-4, while also extending the length of the stage to accommodate more fuel. Though they claim the change will increase the rocket’s range, I suspect however that even with these changes New Glenn’s overall orbital payload capacity will be reduced.

Second, the change indicates that development of the BE-4 engine is proceeding slower than expected, threatening their 2020 launch goal. They have had one test failure that set them back, and the change suggests to me that they are having issues with making the engine restartable.

Third, if they have problems making the BE-4 engines restartable, this means their plans to reuse the first stage of New Glenn will be impacted. While those first stage engines do not need to restart on any single flight, reusing them requires this capability.

Fourth, problems with the BE-4 might cause ULA to reject it and choose Aerojet Rocketdyne’s AR-1 engine for its new Vulcan rocket. Up to now ULA has indicated it prefers the BE-4. These issues might change that.

Fifth, this change, combined with the continuing lack of New Shepard test flights, suggests that the company is increasingly considering abandoning this suborbital spacecraft.

I am doing a lot of speculating here, and could be very wrong on many if not all of these suppositions. We shall have to wait and see.

World View launches first balloon flight since explosion, raises $26.5 million

Capitalism in space: World View today launched its first Stratollite balloon flight since one exploded on December 19 as it was being prepared for launch.

The flight was commissioned by the NASA Flight Opportunities program office for two principal customers, the NASA Ames Research Center and Space Environment Technologies, both of which are studying radiation detection and its energy levels at different altitudes. The balloon vehicle is expected to gather data and stay aloft for less than 24 hours, depending on winds and landing conditions, a World View spokesman said.

More important, the company announced that it had raised $26.5 million in investment capital. All told, it is estimated that the company has raised $48.5 million in three rounds of fund-raising.
