Northrop Grumman completes test of Omega rocket 2nd stage

Capitalism in space: Northrop Grumman yesterday successfully executed a static fire test of the second stage of its OmegA rocket, set for first launch next year.

The first two stages are solid rockets, based on the solid rockets used by the space shuttle. They still have to test the liquid-fueled third stage.

The rocket’s development has essentially been funded by the military, and will thus be used mostly by them to launch national security payloads.

Another professor arrested for lying about working with China

Another professor, this time from the University of Tennessee, has been arrested for lying about his ties to China in a NASA proposal.

Anming Hu, an associate professor in the department of mechanical, aerospace and biomedical engineering at the university’s flagship Knoxville campus, was charged with three counts of wire fraud and three counts of making false statements…

Prosecutors say Hu defrauded the National Aeronautics and Space Administration by failing to disclose the fact that he was also a professor at the Beijing University of Technology in China. Under federal law, NASA cannot fund or give grant money to Chinese-owned companies or universities.

According to the indictment, as the University of Tennessee last December was preparing a proposal on Hu’s behalf for a NASA-funded project, Hu provided false assurances to the school that he was not part of any business collaboration involving China.

I wonder how much technical information he passed to China’s space effort.

First image of possible asteroid in orbit around the Earth

asteroid orbiting the Earth?
Click for full image.

The Gemini telescope in Hawaii has produced the first image of what might be only the second asteroid ever discovered in orbit around the Earth.

The newly discovered orbiting object has been assigned the provisional designation 2020 CD3 by the International Astronomical Union’s Minor Planet Center. If it is natural in origin, such as an asteroid, then it is only the second known rocky satellite of the Earth ever discovered in space other than the Moon. The other body, discovered in 2006, has since been ejected out of Earth orbit. 2020 CD3 was discovered on the night of 15 February 2020 by Kacper Wierzchos and Teddy Pruyne at the Catalina Sky Survey operating out of the University of Arizona’s Lunar and Planetary Laboratory in Tucson, Arizona.

The photo to the right has been cropped to post here. The streaks are stars, since the telescope was tracking the asteroid in an attempt to cull the most resolution of it from the image.

This object is only a few yards across, and could very well be a piece of space junk from a mission launched many decades ago. It is also not in a stable orbit around the Earth, and is expected to be ejected from that orbit in April.

The coming small satellite revolution

Today I received a press release from the Universities Space Research Association (USRA), announcing a half-day symposium in Washington, D.C. on March 26, 2020 entitled ““The SmallSat Revolution: Doing More with Less.” The announcement was an invitation for the working press to register and attend, noting that the speakers will include, among others, Thomas Zurbuchen, NASA’s associate administrator science, Jeffrey Mamber, president of NanoRacks, and Patricia Cooper of SpaceX.

As interesting as this might sound at first glance, I will not attend. For one thing, it is on the other side of the continent, and I can’t afford to fly cross country for such a short meeting. For another, I don’t see the point. I attended a lot of these DC symposiums when I lived in Maryland, and though they were often very educational and the free food (paid for almost always by the taxpayer) was always enjoyable, I routinely found them somewhat lacking in newsworthy content.

Thirdly, and most important, yesterday I attended a much more newsworthy one day conference here in Tucson on exactly the same subject, dubbed the Arizona Academic CubeSat Symposium. Unlike the Washington event above — which will likely be a mostly superficial look at the burgeoning cubesat industry — yesterday’s symposium was focused on letting students and scientists describe actual and very ambitious cubesat projects presently under construction or design.

In less than seven hours I saw the following:

VIPER lunar rover delayed, NASA seeks new bids for delivering it to Moon

NASA earlier this week revealed that it is delaying the launch of its VIPER lunar rover until 2023, even as it announced that it is seeking new bids from commercial companies for delivering it to Moon.

In the past two months NASA has apparently been trying to reorganize its unmanned lunar exploration, resulting it a variety of puzzling and sometimes sudden shifts in policy and direction. First they announced they are going to issue a request for proposals, then they delayed it, then they issued it only to withdrew it one week later, with no explanation.

This week’s announcement is another attempt to release this request, accompanied by the delay in VIPER. Though NASA says the delay is to allow “for upgrades so that the rover can conduct longer and more exciting science on the Moon”, I think instead it is to simplify it so that the commercial companies will be able to launch and land it. VIPER’s heritage designs come from an earlier NASA rover project dubbed Resource Prospector that was cancelled because it was going to be too expensive and complex. I think the private companies building landers for such a rover told NASA that they couldn’t handle those heritage designs, forcing NASA to rethink.

If my suspicions are true, this is actually a very good sign. NASA is allowing the private sector to guide it in ways to save money and work more efficiently. That guidance might cause some initial delays as NASA shifts course, but in the long run it will make for a better run operation, costing less while accomplishing more.

Chinese scientists publish radar results from Chang’e-4 lander

Layers as seen below ground by Chang'e-4 radar

The new colonial movement: Chinese scientists today published their first ground-penetrating radar results from their Chang’e-4 lander on the far side of the Moon.

Using a ground-penetrating radar instrument on Chang’e-4, researchers have found that the rover is likely sitting on different layers of ejecta—debris from multiple impacts over time that rained down at high velocities to blanket the lunar surface and now fill the crater. “[We] see a very clear sequence of [layers],” says Elena Pettinelli of Roma Tre University in Italy, one of the paper’s co-authors.

The rover’s radar instrument was able to penetrate up to 40 meters below the surface of the moon, more than twice the distance achieved by its predecessor, the Chang’e-3 mission, which landed on the lunar near side in December 2013. Data from the latest mission show three distinct layers beneath the rover: one made of lunar regolith, or soil, down to 12 meters; another made of a mix of smaller and larger rocks down to 24 meters; and a third with both coarse and fine materials extending the rest of the 40-meter depth.

The figure to the right comes from the paper [pdf] Though the layers have not been dated, their differences suggest different past events in the formation of this surface.

These results are excellent, but they also have many uncertainties. Radar can tell you a lot, but the only way you can really ever know anything about what’s below ground is to go there and actually do some digging.

Starship moved to launch site

Capitalism in space: SpaceX’s Starship-SN1 prototype has been transported to its launch site at Boca Chica in preparation for a series of tests prior to its first launch hop, hopefully to a height of 12 miles.

Whether SN01 is still destined for flight, it’s safe to say that Starship SN01 tank testing could begin in a matter of days — SpaceX currently has early-morning roadblocks indicative of such testing scheduled from February 29th to March 2nd. SpaceX is likely to kick off by filling SN01 with water to check its tanks for leaks, followed by liquid nitrogen – chemically neutral but still incredibly cold. After that, SN01 would likely graduate to Raptor engine installation and a wet dress rehearsal (WDR) with liquid oxygen and methane before moving on to a static fire attempt, if all goes well.

I have embedded below the fold a fifteen minute video showing the transport operation. The pace is slow, so I suggest playing it at 2x normal speed, using the settings.

My immediate thought in watching this video is that SpaceX’s mobile transport vehicle certainly cost far less than the two mobile launchers NASA built for SLS (for a cost of about a billion dollars). In fact, SpaceX’s entire Starship development program will likely cost less than what NASA spent on just its mobile launchers.

Sea Launch launch platform finally moving to Russia

A giant Russian ship has arrived in California and has loaded for transport to Russia the Sea Launch giant mobile launch platform that now belongs to the Russian airline company S7.

The tale behind this move is long and convoluted. Sea Launch had been a partnership between Boeing, Russia, and the Ukraine, designed to lower the cost to launch with a launch platform that could be moved into the best location for each launch. After a launch failure the company went bankrupt, however, and Boeing wanted out. In addition, Russia invaded the Crimea, going to war against the Ukraine, making that part of the partnership impossible.

Russia didn’t have the money to buy Boeing out, so Boeing put a lien on the platform, preventing anyone from using it. Eventually, Russia paid Boeing off by providing the company several passenger seats on their Soyuz spacecraft that it could sell, which as far as I can tell have not been used. Along the way the Russian airline company took possession, though in truth it is really the Russian government in charge. They hope to use it to launch a next generation Soyuz rocket upgrade, supposedly built by S7.

Northrop Grumman completes first robotic docking to a satellite

Capitalism in space: Northrop Grumman’s Mission Extension Vehicle (MEV) on February 25, 2020 completed first robotic docking to a satellite for the express goal of extending that satellite’s life.

This was the first time ever that a commercial robotic satellite docked with a second commercial satellite for such a purpose. It was also the first time such a docking has been done using no government funds.

More information here.

MEV-1 will stay docked to this satellite for about five years, providing it attitude control and guidance. The robot will then move the satellite into a safe graveyard orbit, detach, and be then capable of docking with a second satellite to extend its life as well. Moreover, Northrop Grumman is building a second MEV, with the hope it will be hired to save other satellites.

This achievement lays the foundation for a new stage in commercial space. It proves that unmanned robots can dock with objects in space, both to repair them and extend their life, but also to remove them from orbit and thus reduce the quantity of space junk.

Building an artificial pond

An evening pause: This engineering not only illustrates the human ability to develop complex technology, it also illustrates how difficult it can be to accomplish what nature does naturally. Think about this the next time you hear someone talking about terraforming Mars.

Virgin Galactic losses grow in second public report

In its second quarterly report, Virgin Galactic’s losses grew from $46 million to $73 million, even as the public trading value of its stock value has skyrocketed in the past few months.

The company is also about to start taking deposits from new customers for suborbital tourist flights.

Whether this will happen, and be profitable, remains an unknown. The company has taken so long and spent so much developing its suborbital spaceship that they are now being overtaken by orbital space tourism.

SpaceX gets approval for Starship/Super Heavy factory in LA

Capitalism in space: Having abandoned plans to build its Starship/Super Heavy rocket factory at the Port of Los Angeles in 2019, SpaceX has changed its mind and now gotten approval for the factory from the LA City Council.

First announced in March 2018 and abandoned for about a year beginning in March 2019, SpaceX has refreshed plans to build giant rocket parts in a California port, simplifying aspects of the original proposal and relying heavily on the fact that steel is far easier to handle than carbon fiber. Now, the company wants to refurbish and repurpose a number of old abandoned buildings already present at Port of LA Berth 240, effectively replicating a somewhat smaller version of the Starship production facilities SpaceX is in the middle of building in South Texas.

With Los Angeles Harbor Commission and City Council approvals both safely in hand, SpaceX’s Port of LA Starship is now officially a question of “when”, not “if”. When the concept first popped back into the public discourse late last month, it came alongside a report from CNBC reporter Michael Sheetz that SpaceX wanted to start building Starship parts as few as 90 days after it reapproached Port officials.

The speed in which SpaceX is moving here is very typical for the company. Bodes well for real test flights both this year and next.

Europe considering delaying ExoMars2020 two years

The Europe Space Agency (ESA) is considering delaying the launch of its ExoMars2020 Mars rover two years because of continuing problems with its parachutes.

According to a spokesperson for the European Space Agency (ESA), a “working-level review” for the project was held among ESA and Roscosmos officials in late January, and a preliminary assessment was forwarded to the respective heads of the space agencies, Jan Wörner of ESA and Dmitry Rogozin of Roscosmos, on February 3. “They instructed the respective inspectors general and program chiefs to submit an updated plan and schedule covering all the remaining activities necessary for an authorization to launch,” the ESA spokesperson said. “This plan will be examined by the two agency heads who will meet on 12 March to jointly agree the next steps.”

It appears that the European and Russian officials will make a public announcement about ExoMars next month. Their options include pressing ahead with a launch this year or delaying two years until the next favorable window for a launch to Mars opens. Given multiple issues with the mission, a source said a delay is the most likely option.

The parachutes are not the only problem. They have just discovered during thermal testing that the glue used in the the hinges of the rover’s solar panels comes unstuck.

In August 2019, when the parachute issues were first revealed (after much hemming and hawing by ESA officials), I predicted a 50-50 chance they’d delay. When in September 2019 the problems were found to be more serious than first admitted, I lowered the chances of meeting the 2020 launch date to less than 25%.

Right now I predict that the launch of ExoMars2020 will not occur this summer, but will be delayed until the next Martian launch window in 2022. You heard it here first.

Beethoven – Moonlight Sonata

An evening pause: Here what counts is the audience. From the youtube webpage:

Mongkol is a 61-year-old former logging elephant. His captive-held life was spent hauling trees in the Thai forest. His body shape is deformed through hard labor, he lost his right eye and tusk in this brutal logging practice. Mongkol was rescued and brought to Elephants World to spend the rest of his days relaxing peacefully in freedom by the River Kwai. I discovered Mongkol is an extremely gentle, sensitive elephant who enjoys music, especially this slow movement by Beethoven which I play to him occasionally in the day and night.

I think he listens with as much rapt pleasure as anyone who loves Beethoven.

Enclosed Martian canyon, filled with ice

Ice-filled canyon on Mars
Click for full image.

Cool image time! The photo on the right, rotated, cropped, and reduced to post here, was taken by the high resolution camera on Mars Reconnaissance Orbiter on November 21, 2019. The uncaptioned image was simply entitled “Ice-filled Graben.”

The location is on the lower flanks of the giant volcano Alba Mons, which in itself sits north of Olympus Mons and the volcanic Tharsis Bulge. The canyon is called a graben because it was formed when a section of the crust slips downward along parallel faults. It does not have the features of a rill, or lava flow, as it starts and stops suddenly. It probably formed due to the rise of the volcano, pulling apart its flanks along faults, causing some sections then to slip downward.

How do the scientists know this is ice-filled? I suspect they have other data that indicates the presence of water, but there are also clear features inside this canyon that resemble the glacial features found elsewhere on Mars. For example, note the parallel lines near the canyon walls. These indicate past surface levels as well as layers within the ice from cyclic climate processes. The line of pits along the southwest wall, where the surface gets more sunlight, also suggests that this sunlight is causing more ice to sublimate away.

Finally, the graben is located at 46 degrees north latitude, definitely far enough north for such ice to exist, based on ample other research.

College apologizes because teacher accurately quotes historical document

The coming dark age: The head of the University of Oklahoma has publicly apologized for a journalism professor because that professor had, after warning the class, accurately read aloud an historical document that included the word “nigger.”

The heart of the apology says it all:

The professor, a faculty member in History, read from a historical document that used the “N-word” repeatedly. While she could have made the point without reciting the actual word, she chose otherwise. Her issuance of a “trigger warning” before her recitation does not lessen the pain caused by the use of the word. For students in the class, as well as members of our community, this was another painful experience. It is common sense to avoid uttering the most offensive word in the English language, especially in an environment where the speaker holds the power.

This apology is downright hostile to the pursuit of knowledge, and coming from the head of a university is especially appalling.

My regular readers know that I forbid the use of obscenities by commenters, as I oppose the recent cultural trend to make their use ubiquitous and casual. I think it debases everyone, and prevents thoughtful debate. However, if you want to get an accurate sense of history you must have the open-mindedness to tolerate hearing such things in order to understand that history.

Moreover, this administrator assumes that his students are so pathetically weak and delicate that hearing this word would destroy them. Poppy-cock! What is really happening is that he is bowing to the race-mongers and political bullies who have been using their demands on what language to speak to force everyone to endorse their political rule.

The future is grim if it will become impossible to learn anything that might offend you. In fact, in that culture you really will not be able to learn anything at all.

NASA leaning towards long-duration flight for 1st Dragon mission

Capitalism in space: According to one former astronaut as well as a review of photos of the training being given to the astronauts who will fly on SpaceX’s first manned Dragon flight, this Space News article thinks that NASA will make that first flight a long-duration mission.

This Dragon demo mission is officially still planned as a short mission, no more than two weeks. To extend it requires additional training, which the photos appear to show, and would thus delay its launch by as yet an unspecified time period.

The article also cites a third reason NASA is now favoring the long-duration option: The issues with Boeing’s manned Starliner capsule:

Another factor in any decision to extend Demo-2 is the status of the other commercial crew vehicle, Boeing’s CST-100 Starliner. That vehicle flew an uncrewed test flight in December, but software problems during the flight, including one which shortened the mission and prevented a docking with the ISS, have raised questions about whether a second uncrewed test flight will be needed. An investigation into those problems is expected by the end of this month.

Even if NASA decides a second uncrewed test flight of Starliner is not needed, a review of all of the spacecraft’s one million lines of code, and other reviews, is likely to delay a crewed test flight of the spacecraft. NASA and Boeing had previously agreed to make that test flight a long-duration mission, with NASA astronauts Mike Fincke and Nicole Mann and Boeing astronaut Chris Ferguson performing space station training in addition to that for the Starliner itself.

The delay in Boeing’s long duration mission leaves a gap in the schedule for maintaining crews on ISS. Flying Dragon long-duration would help solve that.

Confirmed: Betelguese is brightening, as predicted

More observations have now confirmed that Betelguese is once again brightening, as predicted.

Photometry secured over the last ~2 weeks shows that Betelgeuse has stopped its large decline of delta-V of ~1.0 mag relative to September 2019. The star reached a mean light minimum of = 1.614 +/- 0.008 mag during 07-13 February 2020. This is approximately 424+/-4 days after the last (shallower: V ~ +0.9 mag) light minimum was observed in mid-December 2018. Thus the present fading episode is consistent with the continuation of the persistent 420-430 day period present in prior photometry.

In other words, the star’s dimming, though deeper than earlier dips, was right in line with a well-known variation cycle. While absolutely worth close observation and study, the data now strongly suggests that this is relatively normal behavior for this aging red giant star. It will likely go supernova sometime in the future, not likely now.

Quakes by InSight indicate Mars’ interior is active

Cerberus Fossae

The first seismic results from InSight’s seismometer now show that the interior of Mars is active, with regular moderately-sized quakes.

The Seismic Experiment for Interior Structure (SEIS) instrument – a seismometer developed by an international consortium under the leadership of the French space agency CNES – recorded a total of 174 seismic events between February and September 2019. Twenty of these marsquakes had a magnitude of between three and four. Quakes of this intensity correspond to weak seismic activity of the kind that occurs repeatedly on Earth in the middle of continental plates, for example in Germany on the southern edge of the Swabian Jura hills.

Although only one measurement station is available, models of wave propagation in the Martian soil have been used to determine the probable source of two of these quakes. It is located in the Cerberus Fossae region, a young volcanic area approximately 1700 kilometres east of the landing site.

Cerberus Fossae is a land of cracks and linear depressions located between the giant volcanoes, Elysium Mons to the north and Olympus Mons to the east. It is believed those fissures were caused by the rise of those volcanoes, stretching the crust and cracking it.

This new data from InSight strengthens this theory.

Watch a liberal lynch mob form and riot, in real time

Since the 2016 election campaign, the number of examples of physical attacks by leftists against conservatives, journalists, Trump supporters at campaign events, on college campuses, in restaurants, or simply on the street, has grown so much that they now seem to occur almost every day, and have become ubiquitous. In fact, they have grown so frequent that there are no longer unique and — in that sense — no longer newsworthy.

Just last week for example a couple was arrested for trying to run down two teenage boys with their car because the boys were riding bicycles with Trump flags.

According to an affidavit from Lake County, Indiana, Cailyn Smith, 18, and Kyren Jones, 23, were each charged on Thursday with two felony counts of intimidation and criminal recklessness over the incident involving the teens, who are brothers.

The brothers told police that they were riding their bikes at around 8:30 p.m. when a blue Chevy Malibu “swerved as if the driver wanted to hit them” and they had to ride their bikes into the grass, the affidavit stated.

A woman later identified as Smith then yelled “y’all scared just like your president” and “America is not great [expletive].” The couple reportedly sped off after the boys threatened to call the police.

As I say, this behavior has becoming horribly typical. The American left has become the most intolerant, close-minded, and vicious community I have ever seen in the U.S. in my entire life.

And with each passing day it is becoming even more violent and intolerant, its behavior rising to such levels of blind emotional hatred that we can almost guarantee it will soon lead to murder.

Space Force lobbies for $1 billion extra

The Space Force has put forth an extra wish list of missions/projects that require an $1 billion more above the $15 billion the agency has already requested in the next federal budget for 2021.

While about 10 percent of the request is for classified programs, the remaining funding runs the gamut, from bolstering space situational awareness to accelerating the development of navigational satellites to establishing new commercial satellite communication capabilities in low earth orbit.

Overall this wish list appears properly focused, aimed at upgrading or improving existing space military assets rather than growing the Space Force’s bureaucracy. We shall see over time if this proves true. I can’t help having doubts.

New OSIRIS-REx close-up image of secondary asteroid landing site

Osprey landing site on Bennu
Click for full image.

The OSIRIS-REx science team today released one of the images taken during the spacecraft’s recent close reconnaissance of its secondary touch-and-go landing site on the asteroid Bennu.

I have cropped their oblique image to focus, in full resolution, on that landing site, dubbed Osprey, which is the crater on the left side of the photo. The boulder in that crater “is 17 ft (5.2 m) long, which is about the length of a box truck.”

After the fly-by, the science team had announced that the spacecraft’s laser altimeter had failed to operate, and the images taken by its highest resolution camera (not the camera that took today’s image) “are likely out of focus.”

Based on this image, what look like tiny pebbles inside the crater are actually boulders ranging in size from mere inches to as much as five feet across. If their high resolution images are soft, it will thus be hard to map out the terrain sufficiently to safely make a touch-and-go landing here.

More important, there is still no word on whether they have fixed the laser altimeter. Without it I suspect a landing will be very difficult, if not impossible.

SpaceX seeking $250 million more in investment capital

Capitalism in space: According to anonymous sources, SpaceX is once again seeking more investment capital, this time totaling $250 million.

Last year the company raised $1.33 billion. While not as much as the personal cash that Jeff Bezos has raised for Blue Origin by selling his personal Amazon stock, it has been enough for SpaceX to accomplish far more. Not only is the company about to launch its first manned mission, it has quickly begun assembling its Starlink internet constellation in orbit, while pushing forward on Starship construction.

First SLS launch pushed back again to April 2021

NASA on February 20, 2020 finally admitted that the first SLS launch cannot happen in 2020, and set a new target date no earlier than April 18, 2021.

The previous target launch date in November 2020 was always a pure fantasy. NASA just held off admitting it in order to defuse any political consequences for having a program, building SLS, that will end up taking them almost two decades to complete.

This new launch date is likely the most realistic so far, since the hardware for SLS is actually finally coming together. Nonetheless, if anything at all should go wrong along the way, especially with the full static test firing of the core booster of the first stage scheduled for no earlier than August, then expect more delays, possibly lasting years.

Engineers to use InSight’s scoop to help digging process

Insight’s engineers, having failed to get its mole pile driver to dig down as planned, now plan to use the lander’s scoop to push on the mole in the hope this will prevent it from popping up with each hammer drive.

[T]he mole is a 16-inch-long (40-centimeter-long) spike equipped with an internal hammering mechanism. While burrowing into the soil, it is designed to drag with it a ribbonlike tether that extends from the spacecraft. Temperature sensors are embedded along the tether to measure heat coming deep from within the planet’s interior.

…The team has avoided pushing on the back cap [at the top of the mole] until now to avoid any potential damage to the tether.

It appears to me that they are running out of options. This new attempt carries risks. It could damage the tether required to obtain underground temperature readings, the prime purpose of the experiment. However, if they don’t get the tether into the ground, this will also prevent the experiment from functioning. Thus, this attempt could essentially be a Hail Mary pass, gambling all on one last all-or-nothing gambit.

Airbus to cut 2,362 jobs, citing weak space market

Capitalism in space: Airbus announced this week that it plans to cut 2,362 jobs, citing as the reason “lower performance in space” as well as postponed defense contracts.

This quote from the article is revealing:

Airbus Defence and Space is the third satellite manufacturer to announce layoffs in the past 12 months. Thales Alenia Space said in September it was cutting around 6% of its workforce, following Maxar’s February 2019 announcement that it would dismiss roughly 3% of its employees.

The article however also indicates that 2019 saw a big recovery in geosynchronous satellite orders.

Though not stated, I suspect that part of Airbus’s problem is related to Ariane 6, which it is building in a joint partnership with Safran dubbed ArianeGroup. While designed to be less expensive to build, the rocket is not reusable, and its launch price is simply not competitive. Thus, getting contract orders has been very difficult.

Note also that ArianeGroup announced in November 2018 that it going to cut 2,300 jobs by 2022. I wonder if some of these cuts overlap the newly announced cuts.

Either way, these trims might be a good thing as Airbus and ArianeGroup work to cut their costs. Or they could be a bad thing, indicating that both are having trouble making sales. Only time will tell.
