SpaceX sees no schedule impact from first stage landing failure

8:15 am

Capitalism in space: SpaceX officials expect the first stage landing failure during yesterday’s launch to have little impact on the schedule of upcoming launches.

They also indicated that the cause of the landing failure had something to do with a malfunction in the stage’s grid fins. More important however was this tidbit about the second stage:

Koenigsmann also revealed at the briefing that the rocket’s upper stage, which successfully placed the Dragon cargo spacecraft in orbit, used redesigned composite-overwrapped pressure vessels (COPVs) used to store helium to pressurize the stage’s propellant tanks. SpaceX redesigned those COPVs after a September 2016 pad explosion in order to meet NASA safety requirements for future commercial crew missions.

NASA requires SpaceX to perform at least seven launches with the redesigned COPVs before the agency will allow its astronauts to fly on the vehicle. Koenigsmann said he believed this was the second launch to use the redesigned COPVs, after the launch of the Es’hail-2 communications satellite Nov. 15.

SpaceX appears very unconcerned about getting those remaining five flights, which illustrates their expectation that 2019 will have a substantial number of launches in the first half of the year, prior to the tentative June launch date for the first manned Dragon mission.

The vast southern highlands of Mars

3:34 pm

Small section of Rocky Highlands

Rocky highlands

Cool image time! This week the Mars Reconnaissance Orbiter (MRO) science team made available its monthly release of new images taken by the high resolution camera on Mars Reconnaissance Orbiter (MRO). The image above is just a small cropped section from one of those new images, released under the name “Rocky Highlands.” The image on the right is a cropped and reduced section of the full photograph, with the white box indicating the small section above. If you click on either you can see the full resolution uncropped photograph and explore its complex and rough terrain.

What should immediately strike you looking at the small inset section above is the difficulty anyone is going to have traversing this country. There are no flat areas. Every inch seems to be a broken and shattered collection of ridges, pits, craters, or rippled dunes. And the inset above is only a tiny representation of the entire image, all of which shows the same kind of badlands.

This forbidding place is located in the southern highlands of Mars, north of Hellas Basin and south of the transition zone that drops down to the northern lowland plains. The white cross on the map below indicates the image location, with green representing the transition zone, blue the northern plains, and red/orange the southern highlands..

Falcon 9 launches Dragon; 1st stage return fails

12:32 pm

SpaceX’s Falcon 9 rocket today successfully launched a Dragon cargo capsule to ISS.

Unfortunately, a problem with the first stage had it fail to land on its target landing pad, instead landing in the ocean. This failure is the first in quite some time for a SpaceX first stage. It was the first failure however of their Block 5 first stages, which might impact the manned Dragon launch schedule set for this coming year.

The leaders in the 2018 launch race:

33 China
20 SpaceX
13 Russia
10 Europe (Arianespace)
8 ULA

This SpaceX launch was the 100th successful rocket launch for 2018, the first time the global rocket industry has reached the century figure since 1991, before the fall of the Soviet Union. As SpaceX’s 20th launch this year it sets a new record for launches by a private company. In fact, this total exceeds the average number of launches for the entire U.S. from 2001 to 2016, and clearly demonstrates how SpaceX has not only become the world’s dominate launch company, its effort to foster competition into the launch industry has served to energize it, for everyone.

In the national rankings, China continues to lead the U.S. 33 to 32.

Ariane 5 launches two satellites

7:23 am

Arianespace yesterday successfully placed a South Korean weather satellite and an Indian communications satellite into orbit using its Ariane 5 rocket.

The Indian satellite was initially supposed to launch in the spring, but ISRO pulled it back to India just after its arrival in French Guiana to do more checks on it because of the failure of another satellite using similar components.

The leaders in the 2018 launch race:

33 China
19 SpaceX
13 Russia
10 Europe (Arianespace)
8 ULA

Arianespace had predicted it would do 14 launches this year. As this launch is described as its last 2018 launch, it appears they have fallen short of that prediction.

These standings will be updated later today, assuming SpaceX’s Dragon launch to ISS goes off as scheduled.

The cameras that saved Hubble

11:42 pm

Link here. It is the 25th anniversary this week of the space shuttle mission that installed the two cameras that fixed the mirror issue on the Hubble Space Telescope, and the press release at the link provides a nice short overview of that mission, and what was involved to make it happen.

Of course, for a much more detailed look at this story, you could also buy and read A Universe in a Mirror. There are a lot of very fascinating stories that no single press release can possibly mention that I described with glee in writing this book.

SpaceX recovers fairings from ocean

11:36 pm

Capitalism in space: In its launch on December 3, SpaceX was unable to catch either half of the Falcon 9’s fairings as they floated down by parachute. However, both halves were recovered, and the company plans to try to dry them out and reuse them.

The recovery ship, Mr. Steven, failed to catch either in its giant net. Since both fairings however landed gently in the ocean, and were quickly recovered, the article notes that SpaceX is now considering a change in its method of recover. The method of landing appears to have the fairing halves almost act like small boats, thus protecting the delicate equipment on their interiors. It appears they have increased their waterproofing, and may now only need to get them out of the water quickly to make then reusable.

The basement of Mars

12:15 pm

Hellas Basin ripples

Cool image time! The photo on the right, cropped and reduced to post here, was taken by the high resolution camera of Mars Reconnaissance Orbiter (MRO) on May 2, 2018, and shows some very strange ripples and erosion features in one of the lowest elevation locations on Mars, inside Hellas Basin. If you click on the image you can see the full photograph, at full resolution. There are a lot of strange features here, so make sure you take a look at it. The ripples highlighted in the image are between what appear to be three lower basins, and seem to my eye to be ridges created as liquid ebbed and flowed in the basins, depositing material at the shoreline at repeatedly higher and lower levels.

hellas basin

This particular location is not only in Hellas Basin, but it is also located in the deepest part of Hellas, a curved valley located in the basin’s northwest quadrant, as shown by the darker areas in the overview image to the right. The red boxes are other MRO high resolution images, with the cross indicating where this image is located.

This is the basement of Mars, what could be called its own Death Valley. The difference however is that unlike Death Valley, conditions here could be more amendable to life, as the lower elevation means the atmosphere is thicker. The ripples also suggest that liquid water might have once been here, a supposition supported by other low area images of Hellas Basin, most of which show a flattish dappled surface that to me resembles what one would think a dry seafloor bed would look like. The image in this second link also shows what looks like ghost craters that over time became partly buried, something one would also expect to happen if they were at the bottom of a lake, though this could also happen over time on Mars with wind erosion and the movement of dust.

It is also possible that these features come from lava events, so please take my theorizing here with a great big grain of salt. At the same time, recent results have found evidence of paleo lakes scattered all along the eastern rim of the basin, reinforcing the possibility that these were water filled lakes once as well.

Nonetheless, the ripples in the first image above are truly fascinating, as it is clear that at the highest peaks erosion has ripped those peaks away, leaving behind a hollow shaped by the ripples themselves. These features remind me of some cave features I have seen, where mud gets piled but by water flow, and then is over time covered with a crust of harder calcite flowstone. Later, water then washes out the mud underneath, leaving the curved flowstone blanket hanging in the air.

Here in Hellas Basin it looks like something similar has happened, except that at these peaks the outside crust got broken away, allowing wind to slowly suck out the material underneath, leaving these ripple-shaped pits. Whether it was liquid water or lava that helped create these features, the geology left behind is both beautiful and intriguing. I wonder at the chemical make-up of the crust as well as the materials below. And I especially wonder if there are water sources buried within Hellas Basin.

Falcon 9 first stage successfully flies for the third time

11:51 am

Capitalism in space: During a successful launch today of 64 smallsats, SpaceX successfully landed for the third time the rocket’s first stage.

This first stage flew twice before, in May and August. With this flight it is primed for a fourth flight, I will bet sometime in the next two months.

SpaceX was also going to try to recover half of the fairing, but as I write this there is no word yet on that effort. Also, the deployment of the 64 smallsats will start momentarily and take more than an hour. During the live stream, which you can watch as a replay at the link, it was very clear that one of SpaceX’s commercial goals with this launch was to promote the Falcon 9 as an affordable and viable vehicle for launching smallsats. SpaceX is anticipating the growth of that business, and wants to encourage smallsat manufacturers to buy their services. As I like to say, the competition is heating up.

The leaders in the 2018 launch race:

33 China
19 SpaceX
13 Russia
9 Europe (Arianespace)
8 ULA

China remains ahead of the U.S. in the national rankings, 33 to 31.

Update: What I neglected to mention, partly because I was writing this post while traveling, is that with SpaceX launch the company set a new annual record for the most launches in a year, which is also the record for the most launches in a year by any private company, ever.

OSIRIS-REx at Bennu

10:17 am

OSIRIS-REx has successfully completed its last maneuver engine burn to place it in proximity orbit around the asteroid Bennu.

The link takes you to the live NASA stream, which has been a bit hokey. This event is actually not that visually exciting, a bunch of engineers staring at computer screens awaiting data back from the spacecraft indicating that all has occurred as planned. In fact, some felt a bit staged, though the actual event was really happening.

The OSIRIS-REx team has released relatively little data so far, compared to most NASA missions. There will be a press conference in a week when they say they will release more information. I guess we will have to wait until then.

Update: the live stream has shifted to the docking of the manned Soyuz capsule at ISS, which is in itself a more riveting event than OSIRIS-REx’s last engine burn.

Russian Soyuz successfully launches three astronauts

8:01 am

A Russian Soyuz rocket today successfully launched three astronauts on a mission to ISS, less than two months after an early launch had resulted in a launch abort.

Hopefully by the end of 2019 American astronauts will no longer have to rely on Russian rockets for their access to space.

The leaders in the 2018 launch race:

33 China
18 SpaceX
13 Russia
9 Europe (Arianespace)
8 ULA

China remains ahead of the U.S. in the national rankings, 33 to 30.

All these numbers will change repeatedly in the next few days, as their are a number of launches scheduled, including a SpaceX launch later today, when they will attempt, for the first time, to reuse a first stage for the third time.

NASA commits $2.6 billion for commercial lunar exploration

8:49 pm

NASA today announced that it has committed $2.6 billion over the next ten years to buy delivery services to the Moon for its unmanned scientific missions, provided from nine different private companies.

The companies selected — Astrobotic Technology, Deep Space Systems, Draper, Firefly Aerospace, Intuitive Machines, Lockheed Martin Space, Masten Space Systems, Moon Express, Orbit Beyond — cover a range of companies from the well established to new companies not yet proven. This announcement essentially permits them all to bid on providing NASA delivery services to the moon for small unmanned probes. The press release states that:

These companies will be able to bid on delivering science and technology payloads for NASA, including payload integration and operations, launching from Earth and landing on the surface of the Moon. NASA expects to be one of many customers that will use these commercial landing services.

More information here. UPDATE: Doug Messier has published the press releases from most of the above companies, describing their individual projects, and I have added links to each.

The program appears modeled after NASA commercial cargo and crew programs, whereby the companies will own and control the orbiters, landers, and rovers they build, allowing them to market them to others for profit. It also appears designed to keep costs low, as did commercial cargo program. NASA is merely the customer.

This is good news. It suggests that the American space industry is continuing to transition away from big government programs, controlling everything, to a robust private industry that is in charge with the government merely one out of many customers.

More ice cliffs found on Mars!

4:26 pm

Another ice cliff

In my review of the November image download from the high resolution camera on Mars Reconnaissance Orbiter (MRO), I am, as a cave explorer and cartographer, naturally attracted to any image with “pit” in the title. The image to the right, cropped, rotated and reduced to post here, was released with the title “Pit in Mid-Latitude Mantle”. That immediately caught my eye, and in looking at it I was at first unimpressed. The three apparent collapses are interesting in that they all have south-facing sharp cliffs, but other than that I wasn’t sure why they were of interest.

Then I took at look at this image’s location. It is somewhat far south on Mars, at latitude -60 degrees, sitting south of Hellas Basin, the deepest basin on Mars. This location is in the same general area where scientists announced in January the discovery of eight cliffs with visible exposed ice layers. The white horizontal bar below Hellas Basin on the map below and to the right shows the region where seven of those ice cliffs were located. To quote the January press release:

The location of known ice scarps on Mars

These eight scarps, with slopes as steep as 55 degrees, reveal new information about the internal layered structure of previously detected underground ice sheets in Mars’ middle latitudes.

The ice was likely deposited as snow long ago. The deposits are exposed in cross section as relatively pure water ice, capped by a layer one to two yards (or meters) thick of ice-cemented rock and dust. They hold clues about Mars’ climate history. They also may make frozen water more accessible than previously thought to future robotic or human exploration missions.

Researchers who located and studied the scarp sites with the High Resolution Imaging Science Experiment (HiRISE) camera on MRO reported the findings today in the journal Science. The sites are in both northern and southern hemispheres of Mars, at latitudes from about 55 to 58 degrees, equivalent on Earth to Scotland or the tip of South America. “There is shallow ground ice under roughly a third of the Martian surface, which records the recent history of Mars,” said the study’s lead author, Colin Dundas of the U.S. Geological Survey’s Astrogeology Science Center in Flagstaff, Arizona. “What we’ve seen here are cross-sections through the ice that give us a 3-D view with more detail than ever before.”

In an email correspondence today with Dr. Dundas, he confirmed that the image to the right was of ice cliffs not included in the January paper. The image was a follow-up of an earlier MRO image and was taken to confirm the ice cliff’s existence.

What I noticed in reviewing the January paper was that these three new ice scarps were actually outside the white bar on the map above, located at -60.7 degrees latitude, 83.5 degrees longitude.

Blue Origin reveals more details about New Glenn

9:00 am

Capitalism in space: Blue Origin’s release of a payload user guide has provided space geeks a wealth of new information about the design of its New Glenn orbital rocket.

Numerous other items of interest are mentioned on the Guide, with launch vehicle specific elements such as a large common bulkhead being employed on the second stage and common tooling on the second stage and that is also aluminum orthogrid material in its construction. The rocket will use autogenous pressurization for both stages.

The large 7 meter fairing has the ability to launch very large payloads such as space telescopes, but also dual payloads – not unlike Ariane 5 regularly conducts.

The Guide refines some performance numbers, with 1060 kN (240,000 lb) total thrust cited for the second stage, which is slightly down from the 125,000 lb per BE-3U – the second stage engine-performance previously stated by Blue Origin’s online resources.

The article at the link also provides some updates on the status of the construction of the rocket’s launchpad, landing barge, and manufacturing facility.

South Korea test flies its first home-built rocket engine

8:54 am

The new colonial movement: South Korea yesterday successfully completed a suborbital test flight of its first home-built rocket engine.

The 75-ton-thrust engine was fired up and launched the first-stage rocket at the Naro Space Center in Goheung, South Jeolla Province, at 4 p.m., as part of the country’s long-term project to launch the Korea Space Launch Vehicle-2 (KSLV-2), dubbed Nuri, in 2021.

The Ministry of Science and ICT said it achieved an engine burn-time of 151 seconds, which exceeded its goal. It earlier said the test launch would be considered a success if the engine maintained a burn-time of about 140 seconds. The test rocket also reached a maximum altitude of 209 kilometers, 319 seconds after liftoff, and safely landed in international waters southeast of Jeju Island.

The planned orbital launch in 2021 makes this one of many new rockets, from both countries as well as private companies, set to become operational in the early 2020s. It looks like that decade will be especially exciting for space.

Analysis of InSight’s landing site

8:42 am

Link here. It appears they landed within a small crater filled with sand.

InSight landed in what’s called a hollow, a crater that has been filled in with soil and leveled flat. In images taken from the elbow of the lander’s stowed robotic arm, the edge of the crater is visible. Once the team determines the diameter of the crater—it could be meters, maybe tens of meters—researchers can infer its depth and the amount of sand blown into it. Either way, this bodes well for the heat probe instrument, called HP3, which should penetrate the material with ease. “This is about as good news for HP3 as you could possibly hope,” he says.

Landing in the hollow was fortunate for another reason. InSight didn’t quite hit the bull’s-eye of its target landing zone, and ended up in terrain that, overall, is rockier than desired. But the hollow is mostly devoid of rocks. One, about 20 centimeters across, sits close to the lander’s feet, whereas three smaller ones lie farther away—but none poses a threat to placing the instruments. The hollow is flat and lacks sand dunes, and small pebbles indicate a surface dense enough to support the weight of the instruments. “We won’t have any trouble whatsoever,” Golombek says.

They still need to pin down exactly where the lander is, on the surface. They know, within a few kilometers, but it will take more work to narrow that down to a precise location.

Successful launch tonight for India’s PSLV rocket

10:50 pm

The new colonial movement: India’s PSLV rocket successfully placed 31 satellites into orbit, including an Indian Landsat-type satellite plus 30 commercial smallsats.

This ties India with Japan at six launches for the year. With one more launch scheduled for this year, they should end up ahead of Japan.

The leaders in the 2018 launch race remain unchanged.

33 China
18 SpaceX
11 Russia
9 Europe (Arianespace)
8 ULA

At 95 total successful launches so far this year, 2018 now matches the total from 1993, the last time the global aerospace industry accomplished that many. That year, China and Japan had one launch each, Europe seven, with the rest by Russia and the U.S. Now the wealth is much more widely spread, and has a strong potential to grow significantly in the next few years.

The lava tubes and canyons of Cerberus Fossae

3:08 pm

Cerberus Fossae rock falls

Cool image time! In the November image release from the high resolution camera on Mars Reconnaissance Orbiter (MRO) I found the image on the right (cropped to post here), dubbed “Possible Rock Falls on Steep Slopes in Cerberus Fossae.” You can see the full image by clicking on the photo on the right.

The cropped section focuses on the steep cliffs of this deep canyon, formed when lava flowed down from the giant volcano Elysium Mons almost like water, following the faults created by the bulging volcanoes to carve a long series of parallel canyons more seven hundred miles in length. Not only can individual boulders be seen piled up on the base of the canyon, you can see on the lower right a large section of cliff that has broken off and partly fallen, propped now precariously on the cliff’s steep slope. I would not want to be hiking below it at the base of this canyon.

Elysium Mons and Cereberus Fossae

This photograph itself made me more interested in looking at other MRO images of Cerberus Fossae. The context map on the right shows that MRO has taken numerous images along the length of these faults, indicated by the red boxes. The location of the above image is shown by the white cross, at the western end where the canyons tend to be steep, deep, and pronounced. In taking a look at the many images of Cerberus Fossae, I found a variety of canyons, plus pit chains, lava tube skylights, and one especially intriguing image, posted below, that shows what appears to be an extended collapse along the length of what was once an underground lava tube.

Investigators uncover extensive corruption in Roscosmos

9:05 am

An investigation of Roscosmos by Russian prosecutors has revealed extensive violations of law, all of which occurred in only the last year and a half.

The Russian Prosecutor General’s Office has detected systemic legal violations in the work of State Space Corporation, Roscosmos, between 2017 and the first half of 2018. In total, 1,700 violations had been revealed, Official Spokesman Alexander Kurennoy said, adding that 16 criminal cases had been launched.

“During the period between 2017 and the first six months of 2018, documents on the activities conducted by the previous management of Roscosmos had been reviewed. Systemic violations of the law had been detected, particularly regarding the state’s defense procurement, with research and development work having been conducted improperly. This also concerns the area linked to state-of-the-art engineering, and where work on registering patents on intellectual property is carried out, they had been often disrupted. This includes the deadline of defense missions, where evidence of poor-quality products being supplied had been revealed,” he told reporters.

Furthermore, prosecutors had revealed violations of procurement legislation, namely when it comes to pricing and import substitution. “Also, the situation in the rocket and space industry in general was deemed unsatisfactory since the corporation hadn’t enacted the required controls for the appropriate expenditure of budget funds by all of the enterprises’ branches,” Kurennoy stressed.

I expect this situation in Russia will get far worse, as the corruption is a feature, not a bug, in their government-run centralized aerospace industry.

A cubesat communications satellite for the Moon

8:58 am

Capitalism in space: The smallsat company Surrey Satellite Technology is designing a cubesat communications satellite set for launch in 2021 designed to test technology for providing communications in lunar space.

Surrey Satellite Technology Ltd (SSTL) has today announced that it is designing a low cost 35kg lunar communications satellite mission called DoT-4, targeted for a 2021 launch. DoT-4 will provide the communications relay back to Earth using the Goonhilly Deep Space Network, and will link up with a rover on the surface of the Moon. SSTL is currently in discussions with a number of parties for the lunar mission, and expects to disclose further information on mission partners and funding early in 2019.

Sarah Parker, Managing Director of SSTL, said “SSTL has led the way in pioneering the use of small satellites for over 30 years and we are now raising our sights to change the economics of space around the Moon, and beyond.”

DoT-4 will be the pre-cursor mission for a larger lunar communications satellite to follow in the 2023 timeframe which will carry a more robust payload and which will also have the potential for navigation services. SSTL’s ultimate aim is to launch a full constellation of lunar communications satellites offering full service capability to enable new and regular opportunities for science and exploration and economic development of the space environment beyond Earth’s orbit.

It appears that Surrey is trying to grab the market for providing communications services for both NASA’s Gateway project as well as the number of private small lunar rovers that are expected to launch in the coming years.

I should add that this project probably only exists because Surrey and its investors know that it will have affordable access to space, using the new smallsat rockets coming from Rocket Lab, Vector, and Virgin Orbital.

The MarCo cubesat success

1:29 pm

Mars as seen by MarCo-B

The two MarCO cubesats that successfully relayed data from InSight to Earth during its landing yesterday continue to function, with one even sending back images. The photo on the right, cropped and reduced slightly to post here, was taken by MarCo-B.

Neither of the MarCO CubeSats carry science instruments, but that didn’t stop the team from testing whether future CubeSats could perform useful science at Mars. As MarCO-A flew by, it conducted some impromptu radio science, transmitting signals through the edge of Mars’ atmosphere. Interference from the Martian atmosphere changes the signal when received on Earth, allowing scientists to determine how much atmosphere is present and, to some degree, what it’s made of.

“CubeSats have incredible potential to carry cameras and science instruments out to deep space,” said John Baker, JPL’s program manager for small spacecraft. “They’ll never replace the more capable spacecraft NASA is best known for developing. But they’re low-cost ride-alongs that can allow us to explore in new ways.”

As a bonus, some consumer-grade cameras aboard MarCO provided “drive-by” images as the CubeSats sailed past Mars. MarCO-B was programmed to turn so that it could image the planet in a sequence of shots as it approached Mars (before launch, MarCO-A’s cameras were found to be either non-functioning or too blurry to use).

This engineering test proves that we don’t need to build billion dollar spacecraft every time we wish to send an unmanned scouting ship to another world. Cubesats will soon do the job quite well, and for a tenth the cost.

And there will be a lot of money to be made. Governments and private entities of all types will be eager to buy the services of the garage-built planetary cubesats that private companies are going to soon be building, in large numbers.

Moon rocks for sale!

11:07 am

Several rocks brought back from the Moon by a Soviet unmanned spacecraft will be auctioned off on November 29, and you can buy them legally!

The lunar samples were originally presented by the Soviet government to Nina Ivanovna Koroleva, the widow of Sergei Korolev, the “Chief Designer” of the Russian space program. Under Korolev’s direction, the Soviet Union successfully put the world’s first satellite into Earth orbit and launched the first human into space. His unexpected death in 1966 came before he could see the outcome of the space race to the moon.

Four years after Korolev died, the Soviets launched Luna 16, the first of three robotic lunar sample return missions. Touching down after the U.S. Apollo 11 and Apollo 12 astronauts had come and gone from the moon, Luna 16 deployed an extendable arm to drill and extract a core sample 14 inches (35 centimeters) deep. The 3.5 ounces (101 grams) of soil and rocks that it collected were then deposited into a capsule for their return to Earth.

The display gifted to Koroleva contains three grains of the Luna 16 material, weighing about 0.0007 ounces (0.2 grams). The central fragment is basalt, typical of the moon’s mare (or “seas”) terrain while the adjoining two larger fragments are regolith with glass coatings caused by an micrometeoroid impact, according to Sotheby’s.

…In 1993, the lunar samples were estimated to sell for $30,000 to $50,000 before commanding eight times the higher valuation. The display, which has been held in the same private American collection for the past quarter century, is now expected to sell for $700,000 to $1 million.

I will not be surprised if this item sells for considerably more than $1 million.

Local opposition might delay UK spaceport

8:58 am

The United Kingdom’s first spaceport, proposed for the northern tip of Scotland, faces strong opposition from the local community as well as within the organization that owns the land.

The land is controlled by the Melness Crofting Estate (MCE), a company that represents about 56 local crofters. Three of its seven directors have resigned over how the plans have been handled.

George Wyper, one of those who stepped down, claimed that much of the community had been kept in the dark. In a ballot, 27 crofters voted to press ahead with talks to lease land to the spaceport while 18 voted against. Ten failed to vote and one ballot was rejected. Mr Wyper believes that important details were not shared. ‘Some people did not know what they were voting for,’ he said. ‘It’s getting quite vicious here — with Facebook and things. It’s causing a split in the community.’

He told the Highland Press & Journal: ‘There is quite a split in the community and a lot of bad feeling about this. It could go to the Scottish Land Court, which could take years to resolve.’

While in many ways some aspects of the opposition here reminds me of the opposition in Hawaii to the Thirty Meter Telescope, the difference is that that here it a large percentage of the landowners protesting. They have real standing, and thus are in a much stronger position to shut the spaceport down.

From what I can gather, the source of the problem here falls to the UK government, which apparently has done a very bad job in negotiating this deal.

InSight’s solar panels have opened

9:24 pm

InSight engineers have now reported that solar panels have opened and are functioning properly.

NASA’s InSight has sent signals to Earth indicating that its solar panels are open and collecting sunlight on the Martian surface. NASA’s Mars Odyssey orbiter relayed the signals, which were received on Earth at about 5:30 p.m. PST (8:30 p.m. EST). Solar array deployment ensures the spacecraft can recharge its batteries each day. Odyssey also relayed a pair of images showing InSight’s landing site.

“The InSight team can rest a little easier tonight now that we know the spacecraft solar arrays are deployed and recharging the batteries,” said Tom Hoffman, InSight’s project manager at NASA’s Jet Propulsion Laboratory in Pasadena, California.

This was the last major event in the landing sequence, and with it they can now shift to the slow deployment of instruments over the next few weeks. Results from this spacecraft will not be sudden or spectacular. It is going to take time to get the spectrometer placed and than time to gather quake data.

InSight has successfully landed

12:58 pm

NASA engineers have received confirmation that InSight has successfully touched down on the Martian surface.

Don’t count your chickens yet. They need to wait about five hours for the dust, kicked up by landing, to settle before they try opening the solar panels. That must succeed, or the mission will fail, having no source of power.

The landing information was relayed through the two MARCO cubesats flying past Mars, a landmark engineering achievement that in a sense is more significant than the landing itself. These cubesats have demonstrated that smallsats can do complex interplanetary tasks. Expect a revolution in the planetary space exploration world.

Bennu from 85 miles

8:53 am

Bennu at 85 miles

The OSIRIS-REx science team today released a new image of Bennu, taken by the spacecraft from only 85 miles on November 16, two weeks ago Its contrast has been increased to bring out the details.

The asteroid continues to remind me of Ryugu, a rubble pile of boulders with few smooth spots. I suspect the OSIRIS-REx engineers are going to struggle as much as the Hayabusa-2 engineers are in an effort to find a safe spot to grab a sample. The advantage however for OSIRIS-REx is that the main body of the spacecraft doesn’t have to get as close to the surface as with Hayabusa-2. They will come down only close enough for the robot arm to touch down.

Rendezvous is set for December 3.

Present and future landing sites on Mars

11:50 am

With InSight’s landing on Mars set for 11:54 am (Pacific) this coming Monday, November 26, 2018, I decided to put together a map of Mars showing the location of all the successful landers/rovers, adding the landing sites for the planned landers/rovers through 2020. This will give some context to InSight’s landing site.

Landing sites on Mars

The map does not show the landing sites for the failed Soviet, American, and British landers.

As I noted in describing the Mars2020 landing site, the location of the bulk of these landing sites, along the transition zone from the southern highlands and the northern lowlands, demonstrates the areas of the planet that interest geologists the most. It is here that we find many shoreline features, suggestive of the ocean that many scientists theorize existed intermittently in the northern lowlands. It is here that planetary scientists can quickly gather the most information about Martian geological history. And it is here that they have the opportunity to study the widest range of rock types.

From an explorer’s perspective, however, this approach has its limits. It does not provide us a look at a wide variety of locations. It is not directly aimed at finding lower latitude locations where ice might actually exist. And it is decidedly not focused in studying the planet from the perspective of future colonists. I am sometimes frustrated that we have as yet no plans to send any rovers into Marineris Valles, or to the western slopes of Arsia Mons, the southern most volcano in the chain of three giant volcanoes where there are indications that ice might exist underground, or to any of the places where caves are known to exist where a colony could be built more easily. In fact, the caves on the slopes of Arsia Mons seems a prime exploration target.

Eventually these locations will be explored, likely by private landers aimed at scouting out locations for future private settlements. I am just impatient.

ESA plans Vega rocket upgrades

9:33 am

In order to grab more market share, the European Space Agency today outlined a wide range of upgrades and options it is creating for its Vega rocket.

The article describes versions aimed at the smallsat market, the geosynchronous satellite market, and a recoverable mini-shuttle similar to the X-37B, dubbed Space Rider. All these options are expected to come on line by 2021.

Isn’t competition wonderful? Threatened by loss of market share by SpaceX, Europe has been forced to up its game, something it had been loath to do for decades.

Potentially dangerous bacteria found on ISS

9:24 am

Researchers have found five strains of bacteria on ISS that, while not dangerous now, has the potential to mutate into forms that could be a threat.

When Bezdan and colleagues ran the numbers on the space station microbes, however, they found that they were similar to only three – and rare ones, at that. They report similarities with strains found to date only once – one recovered from neonatal blood in a Tanzanian patient, another from a neonatal urine sample in the US, and the third from a 72-year-old woman with multiple health problems. In total, the researchers report, the eight strains thus “formed a unique ecotype”.

The ISS strains all contained genes associated with drug-resistance. They did not, however, contain combinations associated with high infection rates. Nevertheless, the results are enough for the researchers to sound a warning.

There are a lot of uncertainties here, including a lack of understanding of the effect of weighlessness on these bacteria. Nonetheless, this research highlights an important problem for future interplanetary spacecraft that has generally been ignored: Their small and limited ecology is very vulnerable to this kind of threat.
