Contract cancelled for Vostochny launchpad for Angara

8:54 am

The coming dark age: The Russian government has cancelled its construction contract for the much delayed Vostochny launchpad for their new much delayed Angara rocket.

Deputy Prime Minister Yuri Borisov, who curates the space and defense industry for the Russian government, announced the news on January 23 after the latest meeting with Prime Minister Dmitry Medvedev dedicated to financial problems at Roskosmos. Medvedev singled out Vostochny as a symptomatic example of poor management at the State Corporation. Only five out of 19 facilities were officially completed in Vostochny in the first phase of construction by the deadline last year, Medvedev said, according to the public recap of the meeting released by the Russian government.

After the closed-door event, Borisov told journalists that the aborted contract on the Angara pad cost the project at least six months in delays, but, he essentially admitted that the actual completion of the critically needed facility would be pushed back by around two years. “Let’s not have any illusions, nobody will be able to build (Angara pad) by 2021,” Borisov told reporters about the recent official deadline for the project, “Today, due to the juggling of prime contractors, the deadline is beyond 2021, but it (has to be) no later than 2023, because otherwise, it would be desynchronized with the development of the rocket, which would be ready but no place to launch from.”

These problems suggest that the corruption in Russia’s aerospace industry must be incredibly embedded. They, like our own incompetent federal government, can’t seem to get anything accomplished.

New impact on the Martian south polar cap

10:02 am

New impact on Mars' south pole

Cool image time! The image to the right, cropped to post here, was taken on October 5, 2018 by the high resolution camera on Mars Reconnaissance Orbiter (MRO) and shows a recent meteorite impact that occurred sometime between July and September of 2018 on the Martian polar cap . If you click on the image you can see the entire photograph. As noted in the captioned press release,

It’s notable because it occurred in the seasonal southern ice cap, and has apparently punched through it, creating a two-toned blast pattern.

The impact hit on the ice layer, and the tones of the blast pattern tell us the sequence. When an impactor hits the ground, there is a tremendous amount of force like an explosion. The larger, lighter-colored blast pattern could be the result of scouring by winds from the impact shockwave. The darker-colored inner blast pattern is because the impactor penetrated the thin ice layer, excavated the dark sand underneath, and threw it out in all directions on top of the layer.

Location on edge of south polar cap

It is not known yet the size of this meteorite. The location is shown in the overview image to the right, with the impact indicated by the white dot. The black circle in the middle of the image is the south pole itself, an area where MRO’s orbit does not allow imagery. This location, on the edge of the Martian polar cap, is helpful to scientists because it has excavated material from below the cap, providing them a peek into previously unseen the geology there. Had the impact been farther south, on the thicker cap, that hidden material below the cap would likely not have been exposed.

The cap itself is made up of both ice and frozen carbon dioxide, though the CO2 is mostly seen as frost during winter months that evaporates during the summer.

Blue Origin reveals redesigned New Glenn rocket

9:32 am

Capitalism in space: In a video animation Blue Origin last week revealed a new redesigned version of its orbital New Glenn rocket.

There are a few notable differences between the rocket depicted in the new video and the New Glenn we saw in a similar 2017 animation. For example, the older version featured a payload fairing — the protective nose cone that surrounds spacecraft during launch — that was bullet-shaped and 18 feet (5.4 meters) wide. The current incarnation boasts a 23-foot-wide (7 m) fairing with a traditional snub-nosed look. (A previously envisioned three-stage New Glenn featured this bigger fairing, but this booster variant is no longer part of Blue Origin’s plans.)

And the first stage’s six landing legs will apparently now deploy a bit differently — by unfolding outward from the bottom, much as Falcon 9 legs do, rather than sort of sliding downward.

These changes are almost certainly are the result of the company’s Air Force contract that gave it $500 million in development money in exchange for having a say in how the rocket is built.

For example, I am not surprised that New Glenn now more closely resembles the Falcon 9. The modern American military is not known for its daring or innovation. It had to be sued to finally agree to award contracts to SpaceX. Now that the Falcon 9 is well proven, however, the military bean-counters are probably demanding that New Glenn copy it, rather than introduce innovations of its own.

NASA pulls astronaut for medical reasons from Boeing manned flight

9:16 am

NASA has switched one member of the planned astronaut crew for the first manned Boeing Starliner mission presently scheduled in August because of medical reasons.

Eric Boe, one of three astronauts assigned to the first piloted test flight of a Boeing CST-100 Starliner commercial crew ship later this year has been removed from the mission due to unspecified medical issues, NASA announced Tuesday. He will be replaced by veteran astronaut Mike Fincke.

Boe will take over Fincke’s role as assistant to the chief for commercial crew operations in the astronaut office at the Johnson Space Center. In keeping with long-standing NASA policy regarding medical privacy, no details about the reason for Boe’s reassignment were provided.

The article notes that this is only the sixth time in the entire history of American manned space that such a switch was necessary. I hope Boe’s medical issue is not serious, and wish him well with the hope he will be flying on another Boeing or SpaceX flight quite soon.

Though not directly related to this story, to my mind the real question remains: Will NASA’s bureaucracy let this flight happen in 2019? I think it will have no choice, but it will be dragged kicking and screaming to the launchpad.

Arianespace slashes launch price for Ariane 5

9:10 am

Capitalism in space: Arianespace has announced that it is once again dropping the launch price for an Ariane 5 launch, in order to increase the chances it will win several contracts this year.

Arianespace is competing for two major launch contracts in the Asia-Pacific region that should be awarded this year and expects there could be tenders for another three, said [Arianespace Managing Director and Head of Sales for Asia-Pacific Vivian Quenet].

The article does not mention the actual price, but Arianespace had been charging about $100 million per launch satellite, while SpaceX had been charging $62 million (for a new Falcon 9) and about $50 million (for a reused one).

Rocket Lab gets DARPA launch contract

8:57 am

Capitalism in space: Rocket Lab today announced a new launch contract with DARPA, dedicating the company’s first launch in 2019 to that government military research agency.

DARPA’s Radio Frequency Risk Reduction Deployment Demonstration (R3D2) mission is scheduled for launch in late February and intends to space-qualify a prototype reflect array antenna to improve radio communications in small spacecraft. The antenna, made of a tissue-thin Kapton membrane, packs tightly inside the small satellite for stowage during launch, before deploying to its full size of 2.25 meters in diameter once it reaches low Earth orbit. This high compaction ratio enables larger antennas in smaller satellites, enabling satellite owners to take advantage of volume-limited launch opportunities while still providing significant capability. The mission could help validate emerging concepts for a resilient sensor and data transport layer in low Earth orbit – a capability that does not exist today, but one which could revolutionize global communications by laying the groundwork for a space-based internet.

…The mission, the first of monthly Electron launches this year, will lift-off from Rocket Lab Launch Complex 1 on the Māhia Peninsula of New Zealand. To ensure precise insertion and responsible orbital deployment, the R3D2 payload will be deployed via the Electron Kick Stage to a circular orbit. Using this unique launch method, Electron’s second stage is left in a highly elliptical orbit where the stage is subject to significant atmospheric drag, causing it to de-orbit and burn up to nothing in a reduced time frame. The Kick Stage is then used to deploy the satellite payload to a precise orbit, following which the Kick Stage can perform a de-orbit burn to speed up its re-entry, leaving no orbital debris behind in space. [emphasis mine]

The highlighted sections in the quote above indicate the schedule. Rocket Lab had suggested last year that once it successfully completed its November and December 2018 launches it would in 2019 launch monthly. They are still clearly pushing for that schedule, but it is also clear now that they will not launch in January and their February launch will be late in the month, suggesting the next launch will likely not be in March.

These delays at this point are not significant, though if they do not ramp up to that monthly schedule by the end of 2019 it will be.

This late announcement of a payload for the first 2019 launch also suggests that DARPA was willing to pay a premium to leapfrog over Rocket Lab’s already signed customers. My industry sources also suggest that the U.S. military has in the past few months become very very interested in these new smallsat rockets, and has been approaching them all to arrange future flights.

Moon hit by small meteorite during eclipse

12:57 pm

During the lunar eclipse two days ago on January 20, 2018 amateur astronomers were able to record the impact of a small meteorite.

The MIDAS survey is a Moon-watching that scours video of its surface in the hopes of detecting the tiny flashes associated with meteorite impacts. In this case, MIDAS scored a home run, and it was the first time the system was able to spot an impact during a total lunar eclipse.

“In total I spent almost two days without sleeping, including the monitoring time during the eclipse,” [Jose] Madiedo explained to Gizmodo. “I was exhausted when the eclipse ended—but when the automatic detection software notified me of a bright flash, I jumped out of my chair. It was a very exciting moment because I knew such a thing had never been recorded before.”

The meteorite itself wasn’t terribly large, and is estimated to have only been around 22 pounds.

I have embedded the video of the impact below the fold. It is very short, and the flash is not very impressive, but it still is quite cool.

No Planet X needed

9:11 am

The uncertainty of science: New computer models now suggest that the orbits of the known Kuiper Belt objects can be explained without the need for the theorized large Planet X.

The weirdly clustered orbits of some far-flung bodies in our solar system can be explained without invoking a big, undiscovered “Planet Nine,” a new study suggests.

The shepherding gravitational pull could come from many fellow trans-Neptunian objects (TNOs) rather than a single massive world, according to the research.

“If you remove Planet Nine from the model, and instead allow for lots of small objects scattered across a wide area, collective attractions between those objects could just as easily account for the eccentric orbits we see in some TNOs,” study lead author Antranik Sefilian, a doctoral student in the Department of Applied Mathematics and Theoretical Physics at Cambridge University in England, said in a statement.

When you think about it, having many many scattered small objects in the Kuiper Belt makes much more sense than a few giant planets. Out there, it would be difficult for large objects to coalesce from the solar system’s initial accretion disk. The density of material would be too low. However, you might get a lot of small objects from that disk, which once formed would be too far apart to accrete into larger planets.

The use of the term “Planet Nine” by these scientists however is somewhat annoying, and that has less to do with Pluto and more to do with the general understanding of what it means to be a planet that has been evolving in the past two decades. There are clearly more than eight planets known in the solar system now. The large moons of the gas giants as well as the larger dwarf planets, such as Ceres, have been shown to have all the complex features of planets. And fundamentally, they are large enough to be spheres, not misshaped asteroids.

UAE’s Mars mission on schedule for 2020 launch

8:59 am

The new colonial movement: According to one of the chief engineers for the United Arab Emirates’ (UAE) unmanned mission to Mars, dubbed Hope, the spacecraft is on schedule for its 2020 launch by a Japanese rocket.

If all goes right, Hope will go into Martian orbit in 2021.

The quotes in the article from that chief engineer reveal somewhat the overall shallowness of UAE’s space effort at this point.

Omar Hussain, Lead Mission Design and Navigation Engineer for the Emirates Mars Mission, speaking at the Science Event 2019 held at Mohammed Bin Rashid Space Centre in Dubai, said the team have had to overcome a number of challenges along the way.

“It is too early to talk about a specific date just yet but everything is on track and there have been no delays,” said the 29-year-old Emirati. “Speaking for myself, it has been challenging because I had to switch from planning for Earth-based projects to interplanetary missions.

“It took a lot of education to get to that point as I had never done a mission that goes beyond the Earth’s lower orbits. I had to study how I would get the spacecraft from Earth to Mars.”

The goal with their space program is to help diversify UAE’s economy. It might eventually do this, but for now, they I think are very dependent on the help they are getting from others. Japan is providing the rocket, and India the engineering expertise for the spacecraft.

Problem found with Angara’s most powerful version

8:41 am

The new colonial movement: Engineers of the most powerful variant of Russia’s next generation Angara family of rockets, the Angara A5, have found a serious design issue in the engines that they appear to be having problems solving.

The issue with the Angara A5 was brought to attention by scientists at rocket engine manufacturer Energomash in a paper ahead of a space conference later this month.

The paper, reported by RIA news agency on Friday and published online, said the engines of the Angara A5 could produce low frequency oscillations that could ultimately destroy the rocket.

A special valve had been fitted to mitigate the issue, but in some cases the oscillations continued, it said. Energomash did not immediately reply to a request for comment.

This sounds to me like “pogo,” a somewhat common issue with rockets. A resonance builds up within the engines during launch, and the vibration can grow strong enough to cause serious damage. The Saturn 5 had this issue during its second test launch, requiring a redesign of the upper stage engine hydrogen fuel lines.

With this history in mind, I would still not make that much of a big deal about this issue. The Angara A5 is a new rocket. It simply needs testing in flight followed by engineering revisions to work out these kinks.

The problem will be Russia’s government. Putin wants this rocket flying, for his own political purposes, and the question remains whether he will allow its proper engineering development to proceed at the correct pace. This does not mean development should be slow, but that failure is accepted and allowed for while you maintain a fast pace.

Hayabusa-2 names features on Ryugu

10:37 am

The Hayabusa-2 science/engineering teams have now revealed the names they have given to all the significant features on Ryugu that they have photographed.

To name a place on a celestial body in the Solar System, you must first decide on a theme. For example, the theme for places on Venus is the “names of goddesses”. During discussions between the domestic and overseas project members, suggestions such as “names of castles around the world”, “word for ‘dragon’ in different languages” and the “names of deep-sea creatures” were proposed for the place name theme on Ryugu. After an intense debate, the theme was selected to be “names that appear in stories for children” and a theme proposal was put to the IAU WG. The proposal was accepted on September 25, after which the discussion moved to selecting the topographical features to be named and the choice of name.

The link provides a table describing the meaning of many of the names, which is often quite amusing. For example, Kolobok Crater comes from a Russian story about “A small round bread that ran away from home.”

Kickstarter campaign starts to finance launch of garage-built cubesat

10:19 am

Capitalism in space: PocketQube has initiated a 30-day Kickstarter campaign to fund the launch of its first home-made plastic cubesat.

I have written about this project previously, because it epitomizes the old-fashioned vision of a single guy or gal working in his or her basement or garage to build a new invention. It now appears they are getting close to being ready to launch.

Make sure you watch their video at the first link above. It not only explains what they’ve accomplished so far as well as what they hope to do, it is quite amusing at how it pokes fun at the kind of fake-epic videos we see from NASA, promising big but delivering little. In the case of this project, they are instead promising little, but if they succeed they should deliver big.

This quote from the Kickstarter page though I think reveals once again where the real barriers to commercial space lie:

The biggest risk to the project is licensing. The FCC has placed additional burdens on small satellite operators after an incident earlier this year that resulted in four unlicensed satellites being placed into orbit. Possible delays in our applications could result in Mini-Cubes missing the flight. We do have a backup flight should that happen but it will not launch until 2020 at the earliest.

The quote refers to Swarm’s unlicensed launch of four cubesats in March 2018, and the FCC’s subsequent response, imposing fines and strict reporting requirements on Swarm. It now appears some of those strict reporting requirements have been applied across the board to all cubesat companies, increasing costs and paperwork, and even threatening their viability.

No matter the justification, it is once again the government that stands in the way of the ability of free humans to follow their dreams. I have seen this pattern repeat itself for the last half century, resulting in little space exploration since the Apollo landings. It now stands in the way of a new revolution in commercial space.

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

10:01 am

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

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

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

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

9:42 am

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

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

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

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

Democratic House threatens Webb cancellation

8:35 pm

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

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

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

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

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

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

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

Ariane 6 might be in trouble

8:25 pm

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

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

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

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

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

Stratolaunch ends plan to build rockets for its giant Roc aircraft

8:14 pm

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

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

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

Scientists calculate length of Saturn’s day

6:58 pm

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

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

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

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

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

Volcanic vent between Arsia and Pavonis Monsa

1:14 pm

volcanic vent on Mars

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

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

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

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

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

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

Bill to pay federal workers will not pay those not working

9:00 am

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

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

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

Astronomers begin their 2020 decadal survey

8:46 am

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

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

The new survey appears focused on addressing this.

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

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

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

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

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

8:29 am

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

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

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

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

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

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

New local dust storm activity near silent Opportunity

8:19 am

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

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

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

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

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

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

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