Behind The Black – Robert Zimmerman

Planet-wide groundwater system on Mars

February 28, 2019 9:15 am Robert Zimmerman

Old news: The European Space Agency today released a press release announcing the results of a science paper that appears to have found evidence of a planet-wide groundwater system on Mars.

I call this old news because I reported on this paper a month ago here on Behind the Black: Well water likely available across Mars.

We are now near the end of my February birthday-month fund-raising drive. If anything should justify a donation or subscription, this story should provide it. You can either wait for the mainstream press to rewrite press releases, or you can support my effort to get real news to you now, reported with both enthusiasm and honest skepticism.

I really do hate to brag, but I also don’t believe in false modesty.

Close-up of Bennu’s north pole

February 28, 2019 8:58 am Robert Zimmerman

Click for full image.

The OSIRIS-REx science team has released a very high resolution image taken of Bennu’s north pole region. To the right is the most interesting part of that image, cropped by me to show here.

This image shows a region near asteroid Bennu’s north pole on the terminator line between the asteroid’s day and night sides. The OSIRIS-REx spacecraft’s MapCam camera obtained the image on Feb. 20 while in orbit around the asteroid from a distance of 1.1 miles (1.8 km). At this distance, each pixel covers approximately 4.5 inches (12 cm) of Bennu’s surface. The largest boulder, located slightly left of the center, measures around 52 feet (16 meters) across, which, for scale, is the length of the trailer on a semi-truck.

In other words, if this was a truck stop along an interstate highway, you could see the driver getting out of that semi to head inside for dinner.

The spacecraft right now is not doing much science work. They are in what they call the Orbital A phase of the mission, where they are in a very low orbit along the terminator line between night and day — generally a mile above the surface — and are using this orbit to give the engineering team practice maneuvering at such an orbit while they transition from using the stars to navigate to using landmarks on the surface.

ExoMars prototype test driven from 6,000 miles away

February 28, 2019 8:43 am Robert Zimmerman

The engineering team that will drive ExoMars 2020 on the surface of Mars in 2021 has completed a test drive using an engineering prototype, controlling it from more than 6,000 miles away.

Experts at the European Space Agency’s centre in Oxfordshire completed a series of tests across nearly 6,900 miles (11,000 km) in order to see how the Mars rover reacts to commands across large distances.

When on the surface of Mars, the rover will need to be controlled when it is up to 250 million miles from Earth.

The trials team used a new model called ‘Charlie’ to test hardware, software and to practice science operations for the future European Space Agency (ESA) ExoMars rover, which will look for life on Mars in 2021. The Atacama desert was chosen because it is the closest we can get to a Martian-like environment.

I must admit that every press release from Europe about ExoMars 2020 gives me worried chills. Each release is often filled too much with empty boasts and little substantive detail. Worse, each seems to repeatedly remind me of some guy working in his garage on a weekend project.

The issue could merely be a case of poor press release writing, but something about each release makes these alarm bells go off in the back of my mind. With the launch only about sixteen months away, I hope I am wrong.

Arianespace successfully launches first set of six OneWeb satellites

February 27, 2019 3:44 pm Robert Zimmerman

Capitalism in space: Using a Russian-built Soyuz rocket, Arianespace today successfully launched the first set of six OneWeb communications satellites.

This is the first of 21 Soyuz launches to put the entire OneWeb constellation into orbit. OneWeb also has launch contracts with Virgin Orbit’s LauncherOne.

The 2019 launch standings:

2 SpaceX
2 China
2 Europe (Arianespace)
1 ULA
1 Japan
1 India
1 Russia

It could be argued that this Soyuz launch should be placed under Russia. I place it under Europe because they are the one’s who signed the contract.

The U.S. now leads China and Europe 3-2 in the national rankings.

Waterlike Martian lava flows

February 27, 2019 2:03 pm Robert Zimmerman

Click for full image.

Each month the Mars Reconnaissance Orbiter (MRO) science team highlights with captions about four out of the 300-500 new images released that month.

Of the four captioned images in February, the first was entitled “Almost Like Water,” and focused on the waterlike nature of the lava flow. The image on the right is a cropped and annotated section of that featured photograph, with the yellow arrows indicating the flow directions.

The lava appears to have flowed smoothly around obstructions, almost like water, forming streamlined islands. In the southern part of this image, a branch of the flow diverts around a small crater, and eventually rejoins the main part of the flow. [Visible in the full photograph] Irregular-shaped ring structures appear on the northern end and are related to the volcanic activity that formed the flows.

You can see an example of one of those islands near the top of the above image.

This is hardly the only MRO image showing such flows. In fact, the February image release included a bunch, some of the more intriguing of which I highlight below. These lava flows are seen in many different places on Mars, in a wide variety of geological settings, facts that suggest that volcanic activity was once very widespread and ubiquitous on Mars.

No laser communications system at Tabby’s Star

February 27, 2019 10:32 am Robert Zimmerman

If alien megastructures exist at Tabby’s Star, new research has precluded the likelihood that those aliens are using lasers for communications within those gigantic structures.

[The scientists checked] for laser signatures, on the not unreasonable grounds that any structure large enough to encase a star – Boyajian [Tabby’s Star] is almost one-and-a-half times the mass of the sun – would have an internal communication system, for which lasers would represent a good candidate medium.

In the latest research, Lipman and colleagues decided to test the idea. They analysed 177 high-resolution spectra from the star, gathered by the Lick Observatory’s Automated Planet Finder telescope as part of the Breakthrough Listen Project. They estimated that the data was so detailed that lasers with power greater than 24 megawatts should show up. To hunt for them, the researchers developed an algorithm to perform a pixel-by-pixel analysis of each spectrum in order to identify “spatially unresolved emission lines that meet the criteria for an artificial laser signal”.

The good news is that they found several. The bad news is that a secondary multi-step analysis designed to pick up false positives discounted them all. “The top candidates from the analysis can all be explained as either cosmic ray hits, stellar emission lines or atmospheric air glow emission lines,” they conclude.

We must remember that alien megastructures are the most unlikely explanation for the random light fluctuations of Tabby’s Star. This research helps to strengthen that conclusion.

Europe to build reusable first stage

February 27, 2019 10:15 am Robert Zimmerman

Capitalism in space: Even as Europe works to develop Ariane 6, their non-reusable next generation rocket, Ariane Group and the French are now considering replacing it with a different rocket with a reusable first stage.

Late last week, the European rocket maker Ariane Group and the French space agency CNES announced the creation of an “acceleration platform” to speed development of future launch vehicles. The initiative, called ArianeWorks, would be a place where “teams work together in a highly flexible environment, open to new players and internationally.”

“In this era of NewSpace and in the context of fierce competition, ArianeWorks will accelerate innovation at grassroots level, in favor of mid-tier firms and start-ups, with commitment to reducing costs a major priority,” a news release sent to Ars states.

As part of the announcement, the organizations released a promotional video for the group’s first step—a so-called Themis demonstrator. The goal of this project is to build a multiple-engine first-stage rocket that launches vertically and lands near the launch site. The rocket will be powered by Europe’s Prometheus engine, a reusable liquid oxygen and methane engine that may cost as little as $1 million to build.

Essentially they are copying SpaceX’s Falcon 9 rocket, except for the fuel. And they admit it. Moreover, this action tells us that the problems Ariane 6 has had getting European contracts has become serious enough that they have finally recognized that it simply cannot compete with the new wave of reusable rockets expected in the next decade. Building a new rocket that does not have a reusable capability is not viable in the coming market.

They should have recognized this four years ago, but better late then never.

Beresheet’s second engine burn stopped by computer reset

February 27, 2019 8:40 am Robert Zimmerman

It appears that the second engine burn to raise the orbit of Israel’s privately built lunar lander, Beresheet, did not happen as planned because of an unexpected computer reboot.

In a statement Tuesday morning, SpaceIL and Israel Aerospace Industries (IAI) engineers said they were investigating the malfunction, but said that other than a known problem with the navigation system’s star tracker, the Beresheet’s systems were all functioning properly.

The maneuver was scheduled to take place Monday night, as the spacecraft passed near the Earth in an area where the Ramat Gan-based SpaceIL ground crew would not be in direct communication with the craft.

During the pre-maneuver phase, the spacecraft computer reset unexpectedly, and the maneuver was automatically cancelled.

The question that immediately comes to mind: Did they purchase a space-hardened computer? Cosmic rays can wreck havoc on computer memory, causing just this type of unexpected reset, so computers in space need to be much better shielded than on Earth.

Bad climate science, bad climate journalism

February 26, 2019 1:17 pm Robert Zimmerman

The coming dark age: It appears that the most fundamental concept of science, that all research is subject to skepticism, questioning, and doubt, is no longer followed by the world’s leading science journal Science, in either the research or journalism it publishes.

In reporting today how the Trump administration is establishing a climate review panel that will include global warming skeptics, this so-called science journal describes this effort as follows:

The White House is recruiting researchers who reject the scientific consensus on climate change for its “adversarial” review of the issue.

The proposal to form a “Presidential Committee on Climate Security” at the National Security Council (NSC) has shifted, into an ad-hoc group that will review climate science out of the public eye. Those involved in the preliminary discussions said it is focused on recruiting academics to conduct a review of the science that shows climate change presents a national security risk.

William Happer, a senior director at the NSC and an emeritus Princeton University physics professor not trained in climate science, is leading the effort.

Among those who have been contacted are the relatively small number of researchers with legitimate academic credentials who question the notion that humans are warming the planet at a rapid pace through the burning of fossil fuels. A number of the names the White House is targeting are those frequently invited by Republicans to testify at congressional hearings on climate change where uncertainty is emphasized.

The stated goal of the committee, according to a leaked White House memo, is to conduct “adversarial scientific peer review” of climate science. [emphasis mine]

The article also stated that the panel “will also include scientists who agree with the vast majority in the field of climate science that humans are warming the planet at a pace unprecedented in the history of civilization.”

First of all, it is not clear that “a vast majority in the field of climate science” agree with that global warming hypothesis. And even if it was, it would not matter. Science isn’t determined by consensus or majority rule. It is determined by facts, and if the facts don’t support the beliefs of 97% of all climate scientists, all 97% of those scientists are wrong. That this writer and the editors at Science don’t understand this is shocking.

SpaceX first stage for launch abort returns to port

February 26, 2019 8:54 am Robert Zimmerman

Capitalism in space: The first stage that SpaceX used (for the third time) last week to put three payloads into orbit, including Israel’s privately built lunar lander Beresheet, has returned to port and begun its preparation for its fourth launch, the launch abort test required before the company can fly humans on its Dragon manned capsule.

Musk tweeted that the launch escape test could occur in April. Hans Koenigsmann, SpaceX vice president of build and flight reliability, said Friday that teams are looking at whether the in-flight abort could be moved forward from June.

SpaceX plans to reuse the Crew Dragon spacecraft slated to fly to the space station this weekend for the in-flight abort. Assuming a March 2 launch, the capsule is scheduled to splash down in the Atlantic Ocean on March 8, where teams will retrieve the spacecraft and bring it back to Cape Canaveral for the abort test.

The timing of the in-flight abort test “depends on when Crew Dragon comes back,” Musk tweeted. “That’s scheduled for launch next Saturday, but (there’s a) lot of new hardware, so time error bars are big.”

Officials do not expect the Falcon 9 booster to survive the abort test, likely ending its lifetime at four launches, and three intact landings. “High probability of this particular rocket getting destroyed by Dragon supersonic abort test,” Musk tweeted. [emphasis mine]

Unless something significant goes wrong during next week’s unmanned Dragon test flight, the only thing that I see preventing a June or earlier launch abort test would be the paperwork NASA demands SpaceX fill out in order for the agency to rubberstamp the flight.

Beresheet successfully completes first in-space engine burn

February 26, 2019 8:44 am Robert Zimmerman

Capitalism in space: The privately-funded Israeli Beresheet lunar lander has successfully completed its first orbital maneuver.

The 30-second engine burn raised its orbit’s low point by 600 kilometers. They will next do a series of similar maneuvers to steadily raise the orbit’s high point until it carries the spacecraft into the Moon’s sphere of gravitational influence. The actually landing is presently scheduled for April 11.

SpaceIL was set up as a non-profit, with this its only planned mission. However, the subcontractors who built Beresheet’s lander and batteries are now looking into commercializing their capabilities.

Israel Aerospace Industries, which built the lander, has shown an interest in commercializing the platform. In January it announced a partnership with German company OHB to make it available for potential future missions by the European Space Agency or other national space agencies.

Around the time the Falcon 9 carrying Beresheet lifted off, Japanese company ispace also announced milestones in the development of its lunar lander systems. The company announced an agreement with Japanese firm NGK Spark Plug to test its solid-state battery technology on its Hakuto-R lunar lander mission, scheduled for 2021.

Exos to test the reusability of their suborbital rocket

February 26, 2019 8:35 am Robert Zimmerman

Capitalism in space: The smallsate rocket company Exos Aerospace has announced that they have scheduled its first fully reusable test flight of its SARGE suborbital rocket for March 2nd.

Exos completed the Pathfinder Launch on August 25, 2018 from Spaceport America. It was the first step in validating the SARGE SRLV that was flown and recovered for reuse. Exos gathered critical flight data that enabled advancing the design and setting them up for continued reuse of their SARGE vehicle.

,,,The “Mission 1” test flight of the SARGE reusable system will carry the commercial payloads flown under the programs listed below. A successful launch will further solidify the company’s plan to use this technology as the design basis of their Jaguar orbital launch vehicle with reusable first stage capable of carrying 100kg to Low Earth Orbit (200-400km).

The link provides the list of payloads. For their orbital rocket their plan seems straightforward and brilliant. Build a simple suborbital rocket that lands by parachute gently enough so that it can be reused. While using that commercially also use it as the testbed for building an orbital rocket whose first stage would also land by parachute.

This approach puts them in direct competition with Blue Origin and Virgin Galactic for the suborbital business, and likely at a much cheaper price than either. And if the plan works to orbit, it also positions them to be a strong competitor in the smallsat orbital rocket business, being the first with a reusable vertically launched rocket.

Hayabusa-2 touchdown images released

February 25, 2019 8:28 am Robert Zimmerman

Surface of Ryugu 1 minute after touchdown

The Hayabusa-2 science team today released images taken during its quick touchdown on the asteroid Ryugu last week.

The image to the right was taken:

roughly 1 minute after touchdown at an estimated altitude of about 25m (error is a few meter) [80 feet]. The color of the region beneath the spacecraft’s shadow differs from the surroundings and has been discolored by the touchdown. At the moment, the reason for the discoloration is unknown but it may be due to the grit that was blown upwards by the spacecraft thrusters or bullet (projectile).

The image proves that everything on Hayabusa-2 worked as planned, and it almost certainly captured some of that grit.

They are going to do at least two more touchdowns before they have Hayabusa-2 leave Ryugu and head back to Earth.

Most popular theorized particle for explaining dark matter now eliminated

February 23, 2019 11:54 am Robert Zimmerman

The uncertainty of science: The WIMP particle (Weakly Interacting Massive Particle), the most popular theorized particle to explain dark matter, has now been eliminated by experiments.

These experiments have now been ongoing for decades, and have seen no dark matter [WIMPs].

…Theorists can always tweak their models, and have done so many times, pushing the anticipated cross-section down and down as null result after null result rolls in. That’s the worst kind of science you can do, however: simply shifting the goalposts for no physical reason other than your experimental constraints have become more severe. There is no longer any motivation, other than preferring a conclusion that the data rules out, in doing.

Other theorized but less favored particles could still be proved to be dark matter, but the problem is getting harder and harder to solve, as presently assumed.

Dark matter has always been an invention created to explain the too-fast orbital velocities of stars in the other regions of galaxies. It could very well be however that the problem comes not from new physics and a newly contrived particle we can’t see, but from a deficiency in our overall observations of galaxies and what is there, within the constraints of the physics we know now.

Firefly to build and launch from Florida

February 23, 2019 9:35 am Robert Zimmerman

Capitalism in space: The smallsat rocket company Firefly Aerospace announced yesterday that it will build its rocket manufacturing facility at Cape Canaveral, as well as launch from there.

Texas-based launch startup Firefly Aerospace finally revealed its plan to build a manufacturing facility near Kennedy Space Center and outfit the Air Force’s Space Launch Complex 20 in Cape Canaveral for its two core launch vehicles — one of the first manufacturing facilities of its kind in the Sunshine State.

Firefly was shrouded under the codename “Maricopa” for months as Space Florida, the state’s space development agency, trickled out details of a deal that includes an 18-acre chunk of Exploration Park and 28 acres at LC20. The value of the deal is $52 million, and Firefly vows to put 200 of its 300 employees in the Cape.

Firefly’s first rocket, Alpha, will cost $15 million per launch, which means it will either launch a larger bunch of smallsats or they will be serving the larger smallsats in this new industry.

New high resolution images of Ultima Thule

February 22, 2019 5:59 pm Robert Zimmerman

Click for full resolution image.

The New Horizons team has released new high resolution images of Ultima Thule, taken during its fly-by on January 1, 2019.

These new images of Ultima Thule – obtained by the telephoto Long-Range Reconnaissance Imager (LORRI) just 6½ minutes before New Horizons’ closest approach to the object (officially named 2014 MU69) at 12:33 a.m. EST on Jan. 1 – offer a resolution of about 110 feet (33 meters) per pixel.

…The higher resolution brings out a many surface features that weren’t readily apparent in earlier images. Among them are several bright, enigmatic, roughly circular patches of terrain. In addition, many small, dark pits near the terminator (the boundary between the sunlit and dark sides of the body) are better resolved. “Whether these features are craters produced by impactors, sublimation pits, collapse pits, or something entirely different, is being debated in our science team,” said John Spencer, deputy project scientist from SwRI.

Available at the link above is a three-second long movie they created from these images, showing Ultima Thule as it zips across the camera’s view.

Curiosity recovering from safe mode

February 22, 2019 5:44 pm Robert Zimmerman

Last week Curiosity suddenly went into safe mode, halting science operations for four days while engineers analyzed the issue.

Curiosity encountered a hurdle last Friday, when a hiccup during boot-up interrupted its planned activities and triggered a protective safe mode. The rover was brought out of this mode on Tuesday, Feb. 19, and is otherwise operating normally, having successfully booted up over 30 times without further issues.

Throughout the weekend, Curiosity was sending and receiving technical data, communicating with the team in order to help them pinpoint the cause of the issue. “We’re still not sure of its exact cause and are gathering the relevant data for analysis,” said Steven Lee, Curiosity’s deputy project manager at NASA’s Jet Propulsion Laboratory in Pasadena, California. JPL leads the Curiosity mission. “The rover experienced a one-time computer reset but has operated normally ever since, which is a good sign,” he added. “We’re currently working to take a snapshot of its memory to better understand what might have happened.”

…”In the short term, we are limiting commands to the vehicle to minimize changes to its memory,” Lee said. “We don’t want to destroy any evidence of what might have caused the computer reset. As a result, we expect science operations will be suspended for a short period of time.”

As far as I could tell, images were being uploaded to their public image page through February 20, when I did my last rover update. Since then however no new images have appeared. I fear this might be related to the computer issues Curiosity experienced in September that shut down operations for about six weeks and was never quite resolved. Of Curiosity’s two main computers both have now experienced serious problems.

Virgin Galactic’s Unity spacecraft completes 2nd test flight above 50 miles

February 22, 2019 5:00 pm Robert Zimmerman

Capitalism in space: Virgin Galactic’s Unity suborbital spacecraft today successfully completed its seconnd test flight above 50 miles, carrying a test passenger for the first time.

The vessel was ferried up attached to a larger plan called WhiteKnightTwo, dropped into the sky, and then taken up by rocket-powered engine to more than 50 miles above the Earth’s surface just before 9 a.m. local time. It landed safely 15 minutes later. The company said VSS Unity hit Mach 3.04 and traveled to an altitude of 55.87 miles or 295,007 feet, faster and higher than any test flight yet for the vessel.

In addition to the two pilots, Unity carried a test passenger, Beth Moses, the company’s chief astronaut instructor. Besides gathering data, she also unstrapped to experience weightlessness.

The link makes the false claim that this was the first time weightlessness was experienced in a commercial vehicle, even though numerous people have flown weightless on private “vomit comet” airplane flights.

It does appear that Virgin Galactic is finally, after fourteen years, getting close to that first ticketed tourist flight. It also looks possible that they will never quite reach 62 miles, the more commonly accepted definition for the beginnings of space.

NASA okays March 2, 2019 Dragon test flight

February 22, 2019 4:11 pm Robert Zimmerman

NASA has finally approved SpaceX’s unmanned test flight on March 2nd of its Dragon capsule.

They completed the last flight readiness review today, and the press conference revealing this decision is going on right now, at the link. They have noted one issue that came from the review today, relating to questions by the Russians about the software used by Dragon as it docks at ISS. It apparently they did not consider this a reason to delay the launch. They must think they can get it dealt with before the docking. (The manned Dragon docks itself directly with the station, rather than being berthed to the station by the robot arm, as is done with the unmanned cargo Dragon capsule.)

Another batch of caves/pits found on Mars

February 22, 2019 1:10 pm Robert Zimmerman

Four new pits on Mars

Overview of February 2019 pits

In the past year the monthly image releases from the high resolution camera on Mars Reconnaissance Orbiter (MRO) archive have frequently included newly discovered pit entrances. Each time I have written posts highlighting these new pits, in June, July, November 2018 and January 2019. In fact, this is happening so frequently I could almost label it a monthly update!

The November release imaged three pits found on the southern flanks of Arsia Mons. The January 2019 release found several north of the volcano, two of which are very close to the two middle new pits highlighted above. The February release, which is the focus of this post, included four more pits, shown above, all located north and west of Arsia Mons, as shown in the overview map to the right.

Pits 2 and 3 above appear to belong to a cluster of pits all located in the general area between Arsia and Pavonis Mons. (You can see their uncaptioned releases here and here.) Most sit alone on a flat somewhat featureless plain. Sometimes there are flow features nearby, but each pit usually seems to sit unique and unrelated to these other faint features.

Pit 1 is very intriguing in that it sits amid a very long chain of pits and canyons, all aligned, as shown in the image below and to the right.

Global warming in Tucson!

February 22, 2019 10:07 am Robert Zimmerman

Global warming in Tucson!

As I start writing this post it is snowing hard here in normally sunny and warm Tucson. In fact, this winter has been one of the coldest in years, averaging about 15 degrees below average, according to one long time resident and friend. He might have his number wrong, but without doubt this is the coldest winter I’ve experienced since we moved here in 2011. The image on the right was taken looking out across my backyard about ten minutes ago. The city of Tucson and the Santa Catalina mountains should be plainly visible in the distance. Instead, between falling snowflakes all one can see is whiteout.

Obviously, this is proof of global warming!

I am of course joking. A single storm, a single cold winter, or even a half dozen cold or warm winters, are nothing more than weather. Such events tell you nothing about the Earth’s climate or any of its global trends. Unfortunately, the global warming crowd does not seem to understand this. Get the temperature above normal for an hour, and they are screaming about how we are burning up and it is now necessary to abandon our constitutional rights to give the government the power to do whatever it wants, with them in charge.

And when the weather is cold? These same “experts” then claim that this also is proof of global warming. To any rational person, such claims are absurd, and serve only to prove that these experts are untrustworthy.

Today, Tony Heller at his The Deplorable Climate Science Blog put together a masterful essay outlining the failure of these irrational experts, entitled “The Five Top Arguments Against Climate Alarmism”, then summarized what this means in a second essay, “The Malicious Intent Behind Climate Alarmism.” As he so correctly concludes:

We need to have a robust discussion about our energy future centered around engineers – not decisions based on hysteria by politicians and academics who don’t know the first thing about climate or energy. The American people need to be educated, not fed propaganda and have their information sources censored. Our survival depends on an adequate supply of energy, not mindless hysteria and fear over an essential trace gas. Without carbon dioxide, life itself can not exist.

Without a reliable supply of energy, modern civilization can’t exist.

Read both of Heller’s posts. He backs up his conclusions with facts.

And by the way, by the time I finished this short post it stopped snowing. More proof of global warming!

NASA schedules Orion/SLS launch abort test

February 22, 2019 8:29 am Robert Zimmerman

My heart be still! NASA has now scheduled June 12 for its second Orion/SLS launch abort test.

Called Ascent Abort-2, the upcoming uncrewed test will launch from a pad at Cape Canaveral Air Force Station in Florida and last less than 3 minutes. Once Orion reaches an altitude of 31,000 feet (9,448 meters) about 55 seconds after liftoff, the tower-mounted abort rocket motor will rip the Orion space capsule from its booster to simulate a launch emergency escape.

The article also notes that this second abort test follows the last, which took place in May 2010, nine years previously. I want that amount of time to sink in. NASA allowed nine years to pass between its first and second Orion abort tests. Nine years. We fought and won World War II in about a third of that amount of time. The Civil War took about half that time. In fact, it took SpaceX less time to conceive, design, and launch the Falcon Heavy.

Any project that takes this long to accomplish anything is a fraud. It indicates that the goal of SLS/Orion is not to build and fly a manned capsule, but to suck money from the taxpayer for as long as possible.
