Honoring the Apollo 8 astronauts

1:24 pm

Apollo 8 astronauts Frank Borman, Bill Anders, Jim Lovell

They are still here. Fifty years after becoming the first humans to leave Earth orbit and travel to another world, a mission that NASA believed only had a 50-50 chance of success, the three Apollo 8 astronauts are still with us, hale and hearty despite the passing of many years.

On October 6 the Museum of Science and Technology honored all three men with a magnificent event. The picture on the right was taken during that event, shortly after the three men, Frank Borman, Bill Anders, and Jim Lovell (from left to right) had posed for a typical group shot. It far better reveals their personalities, with Borman looking outward, Anders thoughtful, and Lovell laughing.

Borman and Lovell are ninety years old, while Anders is about to turn eight-five on October 17. Yet, all three remain as sharp as they were in 1968, when they circled the Moon. Only the wear and tear of age and time is slowing them down. It was an honor to see them again and shake their hands. It was also sad, as it was clear that time stops for no one, no matter how deserving. Flying to the Moon on a mission that many thought incredibly risky couldn’t stop them. Time unfortunately will.

We are blessed to still have them. Once again during the dinner presentation they talked of their mission, kidding each other repeatedly about what had happened, and talking about why they went and what they thought the future might hold. Borman was pessimistic about the future of space, but then he remains fixated on the concept of a government program for space. Anders meanwhile was in touch with the rise of private commercial space, and advocated that it is where the future lies.

Lovell was Lovell, as always a space cadet, enthused for the future exploration of space, no matter how we do it.

This event is likely only the beginning. Over the next year there are going to many similar events, celebrating the fiftieth anniversary the 1960s Apollo triumph, right through to the landing in July. To me, however, it will always be Apollo 8 that had the most historical impact. Everything that happened afterward merely reinforced what that flight taught us.

Below the fold are two more pictures from the event.

China plans next Long March 5 launch for January 2019

9:19 am

The new colonial movement: China has begun the assembly of the third Long March 5 rocket for its next launch, now set for January 2019.

The article provides the most detailed information yet released about the failure during the rocket’s second launch:

The cause was determined to be damage to the turbopump on one of the two cryogenic YF-77 first stage engines, prompting a redesign of the structure and test-firing in Xi’an.

This is still somewhat vague, though it does confirm that the rocket engine needed a redesign.

Should this January 2019 launch go well, it will allow China to move forward on all of its ambitious space exploration plans, including the building of its own space station, numerous robotic missions to the Moon and Mars, followed eventually with manned missions to the Moon.

Update on SpaceX’s effort to recover/reuse its rocket fairings

9:13 am

Link here. Key paragraph:

SpaceX recently began seriously attempting to recover Falcon 9 payload fairings, albeit almost exclusively during West Coast launches in order to let Mr. Steven attempt to catch the parasailing halves in the Pacific Ocean. Thus far, SpaceX engineers and technicians have not yet solved the challenging problems, although fairing halves have reportedly landed as few as 50 meters from Mr. Steven’s grasp and at least five have been recovered intact after landing gently on the ocean surface. On the East Coast, Falcon fairings are not nearly as lucky, typically alternating between smashing directly into the ocean and landing gently upon it, depending SpaceX’s need for experimental recovery data.

The article outlines some of the technical issues they have been facing, as well as how pieces of some fairings have been recovered many hundreds of miles away by fishermen.

An update on China’s Chang’e-4 lunar lander

7:36 am

Link here. Chang’e-4 is set to land on the far side of the Moon, sometime in December. The article provides some additional details, including information about the likely landing site in Von Kármán crater. It also notes that there are three launches planned at the spaceport prior to the December launch, and that any issue on any of those launches could delay Chang’e-4’s lift-off. .

Ceres’s poles have shifted by as much as 36 degrees

10:31 am

A new analysis of Dawn data suggests that the poles of Ceres have wandered by as much as 36 degrees, and the data also adds further support for the existence of a liquid water layer between the dwarf planet’s crust and mantle.

“The most surprising aspect of this paper is to me the observation that the pole of Ceres must have followed an indirect path to its current pole. A multi-step reorientation could mean that the equatorial density anomaly was still evolving during the reorientation, and this could be because the crust and mantle were weakly rotationally coupled, allowing the crust to start reorienting while the mantle would lag behind,” Tricarico said. “If crust and mantle are allowed to shift with respect to one another, that could point to a layer of reduced friction between crust and mantle, and one of the possible mechanisms to reduce friction could be an ancient water ocean beneath the crust.”

In other words, the crust and mantle are not locked together. Imagine a baseball where the ballcover is not tightly held to the inner core, and slides around it. (Boy there are a lot of pitchers who wish they could get a hand on that baseball.) The cause of that looseness on Ceres is possibly because of a liquid layer in-between the crust and the mantle.

Need I note that there are uncertainties here?

The central peaks of Copernicus crater

9:41 am

Central peaks of Copernicus Crater

Cool image time! Lunar Reconnaissance Orbiter science team has released a new image of the central peaks of Copernicus Crater, shown on the right cropped and reduced in resolution.

Copernicus (9.62°N, 339.92°E), which is easily seen with a moderately powerful backyard telescope, is one of the best-known craters on the Moon. Despite its age (around 860 million years), it is well preserved with over 4000 meters of relief from floor to rim, and the tallest of its central peaks rises approximately 1300 meters above the crater floor. This image, centered on the central peaks, was captured just after dawn (86° incidence angle) as the Lunar Reconnaissance Orbiter slewed west to a 67°angle.

The image is similar to one taken back in 2012, but has a higher resolution because it was shot from 50 miles elevation instead of 75.

This crater was also the subject of one of the first breath-taking images ever taken of the Moon from lunar orbit, by Lunar Orbiter in November 1966.

The wider view taken by LRO gives some context for the image above. The peaks shown in closeup here are part of the lower right grouping. If you go to the first link above you can zoom in and explore all parts of the full image, and see some quite amazing details, including the large boulders scatter throughout the hollows between the peaks.

Giant ice pinnacles on Europa

9:15 am

In a new paper scientists note that getting the congressionally mandated Europa Clipper safely to the surface of Jupiter’s moon might be threatened by the existence there of forests of giant five-story high ice pinnacles.

Probes have shown that Europa’s ice-bound surface is riven with fractures and ridges, and new work published today in Nature Geosciences suggests any robotic lander could face a nasty surprise, in the form of vast fields of ice spikes, each standing as tall as a semitruck is long.

Such spikes are created on Earth in the frigid tropical peaks of the Andes Mountains, where they are called “pentinentes,” for their resemblance to devout white-clad monks. First described by Charles Darwin, pentinentes are sculpted by the sun in frozen regions that experience no melt; instead, the fixed patterns of light cause the ice to directly vaporize, amplifying minute surface variations that result in small hills and shadowed hollows. These dark hollows absorb more sunlight than the bright peaks around them, vaporizing down further in a feedback loop.

This work is based on computer models, so it has a lot of uncertainty. It also appears to assume that these pentinentes will be widespread across Europa’s equatorial regions, something so unlikely I find it embarrassing that they even imply it. I guarantee Europa’s surface will be more varied than that. If they are designing Europa Clipper properly, it will go into orbit first to scout out the best landing site, and will be able to avoid such hazards.

Competing proposals for military space operations

9:05 am

Turf war! Even as Trump is pushing for a new Space Force, the military bureaucracy is proposing competing proposals for rearranging its space bureaucracy.

Some of the details are a bit in the weeds but the following lays out some of the basics

Griffin and Wilson take very different approaches.

In her memo, Wilson suggests the Space Development Agency should be organized under the existing Space Rapid Capabilities Office and that it should be geographically and organizationally connected to U.S. Space Command. She recommends using “existing structures designed and chartered to acquire capabilities rapidly, rather than establishing new structures.”

Griffin is proposing a new D.C.-based agency with a staff of 112 government personnel that would report to him initially, but eventually would shift to the control of a new assistant secretary of defense for space, an office that would first have to be approved by Congress.

In Wilson’s plan, the Space Development Agency and other acquisition organizations would transition to the new Department of the Space Force. She pointedly pushes back on the idea of having an assistant secretary of defense for space or a Space Development Agency that reports to that office. She argues that such a setup would create additional bureaucracy that would be removed from the operators who use and maintain the equipment.

Griffin, a former NASA administrator, seems more focused in his proposal in transitioning the military towards using private commercial assets rather than building its own, but his apparent love for building his own empire might work against that stated goal.

Hubble in safe mode, down to two gyroscopes

8:52 am

The end might be near: The Hubble Space Telescope went into safe mode this weekend when one of its three working gyroscopes failed.

Hubble has six gyroscopes, all of which were replaced by spacewalking astronauts during a servicing mission in May 2009. The telescope needs three working gyroscopes to “ensure optimal efficiency,” mission team members have written, and the failure brings that number down to two (if the “problematic” one that had been off can’t be brought back online).

But that doesn’t mean it’s time to panic. Hubble can do good science with two gyroscopes, or even one, astrophysicist Grant Tremblay, of the Harvard-Smithsonian Center for Astrophysics, said via Twitter Sunday.

While it is true that Hubble can do science on one or two gyroscopes, in that mode it will no longer be able to take the sharp spectacular pictures that represent its great glory.

Hubble was launched in 1990, fixed in 1993, and has been the most successful science robot ever launched. Scientists had hoped, when they made the James Webb Space Telescope their priority in the very early 2000s that both would be in space and operating to provide top notch science data, with Hubble working in visible wavelengths and Webb in the infrared. Webb’s endless delays and cost overruns has now probably made that impossible.

Worse, there are no plans to build a replacement for Hubble. For the first time since 1993, the human race will no longer be able to see, with our own eyes, the universe sharply.

SpaceX successfully launches Argentinian radar satellite

7:36 pm

Capitalism in space: SpaceX today successfully launched an Argentinian radar satellite, while also achieving the first on-land first stage recovery at Vandenberg.

The first stage was a Block 5 that was used and landed on a barge in July, meaning they turned it around in about two months, the fastest turn-around on the West Coast. With this successful landing on land at Vandenberg, they will able to speed up that turn-around time considerably in the future.

The leaders in the 2018 launch race:

26 China
17 SpaceX
8 Russia
7 ULA
6 Europe (Arianespace)

China remains the leader in the national rankings, 26 to 25, over the United States.

NASA pushes upgrades to interim and final SLS upper stages

7:27 am

Because of increased funding to SLS from Congress, NASA is now pushing Boeing to do upgrades to the interim SLS upper stage as well as its final full power upper stage, dubbed the Exploration Upper Stage (EUS) and originally planned for most SLS missions.

Those changes were prompted by the decision NASA made earlier this year to delay the introduction of the EUS. That stage was originally planned to enter use with the second SLS mission, Exploration Mission (EM) 2. Instead, the first flight of what’s known as the Block 1B configuration of SLS has been delayed to the fourth SLS launch, likely no earlier than 2024.

“That has put a slow down on the Exploration Upper Stage work,” said (John Shannon, vice president and program manager for the Space Launch System at Boeing). “We were rapidly approaching the critical design review.”

NASA has asked Boeing to spend some time to try and “optimize” the EUS with the goal of increasing the amount of additional payload it can carry. Such co-manifested payloads, such as modules for NASA’s proposed lunar Gateway, would be carried on the SLS underneath the Orion spacecraft. (emphasis mine)

Shannon also made what might be the biggest understatement I have ever heard when asked about SLS’s endless delays, noting that “We underestimated that somewhat,” referring to the time it has taken to build the rocket.

NASA got Congress to give them extra money to allow more flights of the interim stage, since putting humans on EUS on its first flight was absurdly risky. This way they could also avoid further delays on that first SLS/Orion manned mission, now set for 2023, almost twenty years since it was first proposed. By pushing for more upgrades, they can also justify again stretching the program out longer, thus stretching out the pork without actually flying anything.

The contrast with SpaceX’s development of Falcon Heavy with NASA’s development of SLS continues to be striking. The former was conceived, built, and launched in less than ten years, for a cost of half a billion. The latter remains unflown and unready to fly after fourteen years of development, and likely will not fly for another six years plus. And its development cost will likely top $50 billion by that time.

If I was a customer looking to buy a product, I would laugh NASA out of the room if it tried to sell me its SLS rocket. Unfortunately, the critters in Congress aren’t that smart, and continue to pour money into this dead end project, money that could be much more effectively spent buying rockets from the private sector.

Data from Voyager 2 suggests it is entering interstellar space

7:50 pm

New data since August from Voyager 2 now suggests it is finally leaving the heliosphere of the solar system and entering interstellar space.

Since late August, the Cosmic Ray Subsystem instrument on Voyager 2 has measured about a 5 percent increase in the rate of cosmic rays hitting the spacecraft compared to early August. The probe’s Low-Energy Charged Particle instrument has detected a similar increase in higher-energy cosmic rays.

Cosmic rays are fast-moving particles that originate outside the solar system. Some of these cosmic rays are blocked by the heliosphere, so mission planners expect that Voyager 2 will measure an increase in the rate of cosmic rays as it approaches and crosses the boundary of the heliosphere.

In May 2012, Voyager 1 experienced an increase in the rate of cosmic rays similar to what Voyager 2 is now detecting. That was about three months before Voyager 1 crossed the heliopause and entered interstellar space.

The scientists warn that there is great uncertainty here, and that the actual transition into interstellar space might take longer than with Voyager 1 since Voyager 2 is traveling in a different direction and is leaving during a different time in the solar cycle.

Images of Mascot by Hayabusa released

7:43 pm

MASCOT descending towards Ryugu

The Hayabusa-2 science team today released images taken of MASCOT as it descended to the surface of Ryugu, including images showing where it landed.

In the image on the right, reduced slightly to post here, you can see MASCOT as it slowly moves downward towards the asteroid shortly after its release from Hayabusa-2. At the link there is another image showing the mini-lander as a white dot when it was still about 115 feet above the surface. Other images show its location on the surface where it operated for seventeen hours and completed three hops.

The next big event from Hayabusa-2 will be the spacecraft’s own landing, sometime later this month.

New Horizons makes final big course correction

7:26 pm

New Horizons this week successfully made its final major course correction in preparation for its January 1st fly-by of the Kuiper Belt object the science team has dubbed Ultima Thule.

NASA’s New Horizons spacecraft carried out a short engine burn on Oct. 3 to home in on the location and timing of its New Year’s flyby of the Kuiper Belt object nicknamed Ultima Thule.

Word from the spacecraft that it had successfully performed the 3½-minute maneuver reached mission operations at the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, at around 10:20 p.m. EDT. The maneuver slightly tweaked the spacecraft’s trajectory and bumped its speed by 2.1 meters per second – just about 4.6 miles per hour – keeping it on track to fly past Ultima (officially named 2014 MU69) at 12:33 am EST on Jan. 1, 2019.

As the spacecraft gets closer they will do more refinements, but right now they are a very precise course. The January 1st fly-by will end a spectacular fall season of planetary mission rendezvous, landings, fly-bys and sample gatherings.

IAU names two craters in honor of 50th anniversary Apollo 8 mission

8:33 am

Earthrise

The International Astronautical Union has named two craters “8 Homeward” and “Anders’ Earthrise,” both visible in astronaut Bill Anders iconic Earthrise image, in honor of the upcoming fiftieth anniversary of the Apollo 8 mission to the Moon.

The Working Group for Planetary System Nomenclature of the International Astronomical Union has today officially approved the naming of two craters on the Moon to commemorate the 50th anniversary of the Apollo 8 mission. The names are Anders’ Earthrise and 8 Homeward.

The newly named craters are visible in the foreground of the iconic Earthrise colour photograph taken by astronaut William Anders. It depicts the moment that our shiny blue Earth came back into view as the spacecraft emerged out of the dark from behind the grey and barren Moon. This is arguably the most famous picture taken by Apollo 8. It became iconic and has been credited with starting the environmental movement.

The image is to the right, with the two craters indicated. I have rotated the image so that the horizon is on the right, since is how Anders took it. As I noted in Genesis: the Story of Apollo 8 (now available as both an ebook and audiobook),

Bill Anders’ photograph of earthrise, taken on December 24, 1968, possibly one of the most reprinted photographs ever taken. The way it is usually reproduced, however, with the Moon’s horizon at the bottom, is not how Bill Anders took it.

Instead, the way it is shown on the cover of Genesis: the Story of Apollo 8 is the way he framed it, with the Moon’s horizon on the right. This is also how it is framed at Bill Anders’s home, which also was the first time I had ever seen it oriented that way. When I asked Anders why it was framed that way, he answered, “That’s how I took it.”

To Anders, floating in zero gravity, the earth wasn’t rising from behind an horizon line (which is how a human living on a planet’s surface would perceive it). Instead, floating in a space capsule seventy miles above the moon, Anders saw himself circling the moon’s equator. The lunar horizon therefore appeared vertical to him, and the earth moved right to left as it came out from behind the moon.

In 1968 the IAU had refused to accept some of the astronauts’ naming choices. This honor now somewhat corrects that injustice.

UPDATE: One more historical note: On Saturday there will be a 50th Reunion Dinner for the Apollo 8 astronauts at the Museum of Science and Industry in Chicago. I will be attending, so today is a travel day.

MASCOT ends its mission on Ryugu, as planned

10:52 pm

Hayabusa-2’s mini-lander MASCOT has ended its mission on Ryugu after seventeen hours, slightly longer than the planned sixteen hours.

The lander made one hop, and successfully transmitted all its data back to Hayabusa-2, which still has one more mini-lander on board that will be sent to Ryugu’s surface, probably after Hayabusa-2 makes its own landing.

Meanwhile, the two Minerva-2 bouncers continue to operate on Ryugu.

Commercial crew test flights delayed again

10:43 pm

NASA today released an updated schedule for the Dragon and Starliner test flights, indicating the first Dragon flight has been pushed to January 2019.

  • SpaceX Demo-1 uncrewed flight test: January 2019 (delayed from November 2018)
  • Boeing uncrewed Orbital Flight Test: March 2019 (delayed from late 2018/early 2019)
  • SpaceX Demo-2 crewed flight test: June 2019 (delayed from April 2019)
  • Boeing Crew Flight Test: August 2019 (nominally still in mid-2019 as earlier stated)

It appears from the article that SpaceX was prepared to fly its first flight in December, meaning only a one month delay, but scheduling conflicts at ISS forced them to push it to January.

With the Boeing flights, the scheduling has less to do with delays and more do to do with setting more precise launch dates.

A vent on Mars?

1:29 pm

A vent on Mars?

Cool image time! In their exploration of the surface of Mars using Mars Reconnaissance Orbiter (MRO), scientists often image geological features that strongly resemble Earth features. Sometimes, if real, the resemblances are significant, as they indicate important geological activity on Mars that can tell us a lot about the conditions and environment there.

The image on the right, cropped and reduced in resolution to post here, is a good example of this. It was taken by MRO on June 14, 2018, just before the global dust storm obscured the planet’s middle latitudes for most of the summer, and was part of the monthly release of new images from the spacecraft. (If you click on the image you can see the full resolution picture.) The release website, which includes no caption, describes this feature as an “apparent vent,” a determination that certainly seems reasonable. The shadowed dark features suggest an abrupt oblong pit near the edge of a cliff, formed in the center of a collapsed sink. The tear-drop shape of the collapse sink and surrounding darkened areas also suggests that something is venting from it and then blowing away to the east and south, forming the darker stained ground. Some of the dark features to the southeast might also be smaller vents, releasing their own materials into the atmosphere.

The location also reinforces this suggestion, located on the southeast lava slopes of one of Mars’ larger volcanoes, Elysium Mons. This is also a region, dubbed Athabasca Valles, that some planetary scientists believe is one of the youngest lava flows on Mars.

Finally, it appears that the pit here has darkened considerably recently. MRO has taken images of this pit twice previously, in 2008 and 2010, and in both images the pit is much lighter in color, with its sandy dune-covered floor much easier to see. In the new image the floor is now very dark. This might be caused by shadows and the angle of the Sun, but I don’t believe so. It is also clear when comparing all three images that the surrounding area, including the flow to the southeast, has also darkened with time.

All this data suggests that the pit is venting something into the air, and it is settling on the ground to the southeast, blown there by the prevailing winds. Nor is this pit the only such feature in this region. Other images by MRO show a lot of similar dark splotches.

The problem is that this feature is not on Earth but on Mars. Determining what is being vented, and why, is therefore made more difficult. Based on Earth data you would assume this is some form of volcanic vent, releasing gases from below the surface. On Mars that assumption might not hold. We might instead be seeing the venting of any number of possible materials, such as underground water-ice, carrying with it other underground materials and thus darkening the surface.

We also can’t assume that the venting is occurring because of volcanic processes. On Mars the evidence so far gathered suggests that active volcanic activity ceased a very long time ago, even for this very young lava region. The venting is likely caused by something else, a fact that in itself is probably the most significant take-away from these images.

Something appears to be causing an active vent on the surface of Mars. Finding out the root cause of that venting is probably one of the more interesting questions facing researchers who study the Martian surface.

SpaceX turned down government money to build Falcon Heavy

10:17 am

Capitalism in space: In a presentation yesterday in Europe, one of SpaceX’s executives, Hans Koenigsmann, made it clear that SpaceX paid entirely for the development of Falcon Heavy, and in fact turned down an offer of government funding.

According to the SpaceX executive, the company was actually approached by “the government”, with the unknown agency or agencies stating – in Hans’ words – that they wanted to be a part of the rocket’s development. According to Hans, SpaceX responded in an extremely unorthodox fashion: “we said, ‘Nope! We just wanna build it, you can buy it when it’s ready and we’ll charge you for the service.’” He noted in the next sentence that funding was the primary lever on the table: “It’s a great position to do this, you gotta find the money, you gotta know people that have money and are willing to invest in your company, and [SpaceX has] been lucky enough to know some of those people.”

In other words, when given an opportunity to either rely on government funding or some other source of capital for a given R&D project, SpaceX – or at least Hans Koenigsmann, VP of Reliability – would apparently recommend the latter option in almost all cases. Again, without being prompted, he elaborated on his feelings about funding sources, culminating in a statement that is simply profound coming from an executive in the aerospace industry. The following quote is unabridged and straight from Hans himself:

“You need to [try to not] get money from the government, otherwise the government will tell you what to build and how to build it… they will tell you how to build this and that’s just not always – I mean for some things it’s the best to do, but in others it’s actually not.”

In other words, don’t let the government run your business. Use the government as an eventual customer, but build your product in a way that will not make them your only customer.

You can watch his entire presentation in the embedded video below the fold. Koenigsmann also noted that this Sunday’s first attempt to land a first stage at Vandenberg will likely produce a spectacular show for anyone who watches.

How one region’s space industry represents the world

9:20 am

bumper sticker

On October 2 I attended for the first time a monthly meeting of the Arizona Space Business Roundtable, an informal gathering put together by Stephen Fleming of the University of Arizona’s Strategic Business Initiatives and designed to allow the various space businesses of southern Arizona to network together as well as highlight what they are accomplishing to themselves and to others.

This particular meeting involved the presentation to the business community of a study that looked into the potential growth possibilities for space within the Tucson region. The study had been financed by the University of Arizona, several local venture capital companies, and the local county government, and had found that southern Arizona’s most likely source of space business in the near future would revolve around the need to track and monitor the large number of satellites expected to be launched in the coming decades. This would also involve substantial military work, as well as related space junk clean-up duties. The study also found that the southern Arizona space industry is well suited to provide much of the growing support services that future space missions, both governmental and private, will need. You can read more about the study’s results and the meeting at this Arizona Star article.

What struck me most about this gathering and the space industry of southern Arizona, however, is how much it resembles the regional space industries in numerous other places throughout the United States and the world. In fact, during a panel discussion after the presentation Fleming specifically asked the panelists — made up of several local companies (Vector, Worldview, Paragon) and two venture capital companies — what other regions in the U.S. posed the most competitive threat to southern Arizona. The panelists quickly listed Denver-Boulder, Silicon Valley in California, Huntsville in Alabama, the Space Coast in Florida, and New Mexico. They also made it clear that this list was not complete.

All of these regions are presently prospering and, more important, growing. All see a bright future in space, and all are aggressively competing to grab as large a market share in this future as they can. Even more significant, there appears to be more than enough business to go around. With numerous new countries pushing their own space efforts (China, India, UAE, Great Britain, Luxembourg, to name only a few), and both the American government as well as private companies attempting their own missions to the Moon and beyond, the possibilities appear endless. A lot of government money and investment capital is presently being poured into space, and numerous regions throughout the world are reaching for that money and the future profits it will bring.

And all of these regions are stock full of numerous independent and private companies and individuals, all pushing their own ideas about how space should be explored and conquered.

There are many aspects of the present charge to explore and settle the solar system that I do not like and believe will actually hamper and slow that exploration and settlement. Nonetheless, this charge is happening worldwide, and with amazing and increasing vigor. Even the worst proposals, such as NASA’s Gateway project, are going to eventually lead to new space technologies and capabilities that will sooner or later make it possible for the human race to routinely travel throughout the solar system.

It appears that the next two decades will lay the groundwork for the next few centuries of space exploration. And much of that groundwork will take place out of sight of the general public, with small companies located in regions like these. As with all great endeavors, the structure is that of a pyramid. At the top is the leader (such as SpaceX) that everyone watches and admires. Below it however is a vast subculture that provides the foundation for that leadership, even as it pushes upward to compete against it.

These are exciting times. I suggest if you love space you climb on the rocket now, before it picks up so much speed it will be beyond your reach.

NASA study says deep space will cause cancer and destroy stomachs

8:35 am

We’re all gonna die! A NASA study on rats using simulated space radiation suggests that long duration space missions beyond Earth orbit will cause cancer as well as significant harm to human intestines.

The study, published by cancer researchers at Georgetown University Medical Center, used mice to test exposure to heavy ion radiation, which mimics the galactic cosmic radiation found in deep space. If that sounds complicated, essentially researchers compared “space” radiation to X-ray radiation and found its effects to be much more dangerous.

After long exposures to a low dose of galactic radiation, mice had permanent damage to their gastrointestinal tracts and could no longer absorb nutrients in food. The mice also developed cancerous growths in their intestines — raising concerns that astronauts who venture far into space would face the same deadly health issues. “While short trips, like the times astronauts traveled to the moon, may not expose them to this level of damage, the real concern is lasting injury from a long trip,” said Kamal Datta, head of Georgetown’s NASA Specialized Center of Research, in a press release.

More here.

Must I point out the uncertainties and weaknesses of this study? They did the test on rats. They simulated the radiation. And it appears they simulated the radiation dosages assuming the spacecraft would have little or no shielding, an absurd approach.

Space is dangerous, but there is no reason to exaggerate the dangers wildly, unless you wish to generate fake reasons for additional funding, as NASA is prone to do.

Curiosity to switch computers in effort to restore operations

10:44 pm

The Curiosity engineering team have decided to switch on-board computers in effort to figure out why the rover has been unable to store and send any data since September 15.

After reviewing several options, JPL engineers recommended that the rover switch from Side B to Side A, the computer the rover used initially after landing.

The rover continues to send limited engineering data stored in short-term memory when it connects to a relay orbiter. It is otherwise healthy and receiving commands. But whatever is preventing Curiosity from storing science data in long-term memory is also preventing the storage of the rover’s event records, a journal of all its actions that engineers need in order to make a diagnosis. The computer swap will allow data and event records to be stored on the Side-A computer.

Side A experienced hardware and software issues over five years ago on sol 200 of the mission, leaving the rover uncommandable and running down its battery. At that time, the team successfully switched to Side B. Engineers have since diagnosed and quarantined the part of Side A’s memory that was affected so that computer is again available to support the mission. [emphasis mine]

As indicated by the highlighted paragraph, the switch does carry some risk. Though they say they have isolated the problems with the A computer, they might be surprised when they turn it on.

Meanwhile, silence continues from Opportunity. After fourteen years of almost continuous rover operations on Mars, the United States have been roverless now for more than two weeks.

NASA signs agreement to work with SpaceIL’s privately built lunar rover

11:21 am

Capitalism in space: NASA, the Israeli space agency, and the private Israeli space company SpaceIL have signed a cooperative agreement to work together when SpaceIL’s privately built lunar rover is launched to the Moon in December.

NASA will contribute a laser retroreflector array to aid with ground tracking and Deep Space Network support to aid in mission communication. ISA and SpaceIL will share data with NASA from the SpaceIL lunar magnetometer installed aboard the spacecraft. The instrument, which was developed in collaboration with the Weizmann Institute of Science, will measure the magnetic field on and above the landing site. The data will be made publicly available through NASA’s Planetary Data System. In addition, NASA’s Lunar Reconnaissance Orbiter will attempt to take scientific measurements of the SpaceIL lander as it lands on the Moon.

This agreement is the first step in the transition from having the government build planetary probes to it becoming a customer, buying these probes from private companies that build them for profit.

A new Moon Race contest established

9:51 am

Led by Airbus, a number of private space companies and government agencies have established a new space contest dubbed “The Moon Race.”

The Moon Race competition is a global initiative founded by Airbus and international partners, aiming to boost the movement around Moon exploration and enable the demonstration of key technologies required for its sustainable exploration.

The Moon Race targets startups and SME’s worldwide and has the ambition to bring the winning teams to the lunar surface and provide solutions for the uprising lunar economy.

The competition is managed by “The Moon Race NPO gGmbH”, a not-for-profit organization based in Germany, whose goals are to manage The Moon Race competition and bring together the international space – and non-space – communities into one coordinated international initiative.

The partners listed so far are Airbus, Blue Origin, Vinci (an Italian space company), the European Space Agency, and Mexico’s space agency. Though their webpage is somewhat vague, it appears they are looking for new companies to join a program to compete for monetary prizes handed out year by year though 2023.

ISS’s international partners express interest in extending station’s life

9:42 am

While NASA has been considering the end of ISS, this week its international partners all expressed interest this week in extending its life beyond 2024.

During an Oct. 1 press conference at the 69th International Astronautical Congress (IAC) here, representatives of three ISS partner agencies said they were open to extending the station’s operations to 2028 or 2030 in order to maximize the investment they’ve made in the facility as a platform for research and preparation for exploration activities beyond Earth orbit.

Jan Woerner, director general of the European Space Agency, said the issue could come up at the next triennial meeting of the ministers of ESA’s member nations, scheduled for late 2019. “At the ministerial meeting next year, the ministerial council, I will propose to go on with ISS as well as the lunar Gateway,” he said. “I believe that we will go on.”

At a separate briefing Oct. 2, Woerner emphasized the use of the station as a research platform and encouraged greater commercial activities there. “I believe we should use the ISS as long as feasible,” he said. “I always thought 2024 was the end, but now I learned it is 2028, and yesterday I learned it’s 2030. So, I will try to convince the ESA member states that ESA should be a partner in the future.” However, he noted that ESA could defer the decision on a post-2024 ISS extension until its following ministerial meeting in 2022.

Hiroshi Yamakawa, president of the Japanese space agency JAXA, also emphasized the importance of making the most of the station. “I’d like to make the most of the present ISS,” he said. “We have to maximize the output of the ISS. Whenever the deadline comes to the ISS, we would like to participate in the ISS and maximize output.” He added, though, that there was not a pressing need for Japan to decide on an ISS extension. “JAXA is requesting budgets annually, so I think in that sense JAXA is quite flexible.”

Dmitry Loskutov, head of international relations at the Russian state space corporation Roscosmos, said Russia already expected an extension. “We anticipate the continued functioning until 2028 or 2030,” he said.

While I can see many benefits for extending ISS, leaving it as a wholly government-run operation will reduce its effectiveness while increasing its cost. I also suspect all these agencies are lobbying for funding. If they can get money for both ISS and Gateway, it will increase their footprint in space significantly.

Hayabusa-2’s third mini-lander successfully lands on Ryugu

8:55 am

MASCOT image of Ryugu surface

Update: The image at right, reduced to post here, was taken by MASCOT during its descent. You can see the spacecraft’s shadow in the upper right. If you click on the image you can see the full resolution version.

Original post: The German/French-build mini-lander MASCOT has been successfully deployed by Hayabusa-2 and has successfully landed on the asteroid Ryugu.

MASCOT came to rest on the surface approximately 20 minutes after the separation. Now, the team is analysing the data that MASCOT is sending to Earth to understand the events occurring on the asteroid Ryugu. The lander should now be on the asteroid’s surface, in the correct position thanks to its swing arm, and have started to conduct measurements independently. There are four instruments on board: a DLR camera and radiometer, an infrared spectrometer from the Institut d’Astrophysique Spatiale and a magnetometer from the TU Braunschweig. Once MASCOT has performed all planned measurements, it is expected to hop to another measuring location. This is the first time that scientists will receive data from different locations on an asteroid.

The spacecraft took 20 pictures during its descent, which were beamed to Hayabusa-2 where they are presently stored.

Celebrate Earthrise Day!

1:59 pm

In only a little less than three months we will be celebrating the fiftieth anniversary of the December 1968 flight of Apollo 8 — first manned mission to another world. During that mission three humans spent 20 hours in orbit around the Moon, during which they read the first twelve verses of the Old Testament on Christmas Eve and became the first humans to witness an Earthrise and to photograph it.

To celebrate that achievement, a new website has been created, dubbed Celebrate Earthrise Day.

The website provides some great background material. You can listen to the astronaut’s Christmas telecast as well as see a recreation of the moment when the astronauts saw that Earthrise and Bill Anders took his famous color photo. The site also includes many photos from before, during, and after the mission, with many pictures coming from the personal family pictures of the astronauts. There is also audio of an 1988 Bill Anders’ interview, as well as a video of a fascinating presentation made by Bill and Valerie Anders, describing their life journey leading up to Apollo 8 and afterward.

Finally, and I think of most interest to my readers here, the site includes the audio of my introduction from the new audio edition of my book, Genesis: the Story of Apollo 8.

The site also includes the audio of one of the best radio interviews I have ever done, broadcast in 1998, on the subject of Apollo 8, our American culture, and the importance of each person choosing their path in life wisely. You can find that audio at the bottom of this webpage.

Check it all out. I think you will find it worth your while.

Deployment operations for Hayabusa-2’s MASCOT lander have begun

9:07 am

Engineers have begun the deployment sequence for Hayabusa-2’s MASCOT lander, with deployment planned for tomorrow.

Right now Hayabusa-2 is slowly moving closer to Ryugu, with live images appearing about once every half hour. More information about MASCOT can be found here. The lander can also hop like the MINERVA bouncers, but it can only do it once. Its battery life is about sixteen hours, so once it is deployed it will only operate on the surface for a short while.

Both the MINERVA and MASCOT mini-landers are mostly engineering tests for using small cubesat-sized spacecraft as probes. So far the MINERVA bouncers have been an unqualified success. Hopefully MASCOT will be as successfully.
