Updates on India’s space effort

It appears that India’s effort in space is evolving rapidly, based on several news stories today.

First, the Indian space agency ISRO signed a deal with Microsoft, whereby the software giant will provide support to private Indian space start-ups.

As part of a memorandum of understanding that Microsoft has signed with the Indian Space Research Organization, the firm will also provide space tech startups with go-to-market support and help them become enterprise ready, it said.

Startups handpicked by ISRO will be onboarded to Microsoft for Startups Founders Hub platform, where they will receive free access to several tools and resources. These tools include help with building and scaling on Azure, as well as GitHub Enterprise, Visual Studio Enterprise, Microsoft 365 and Power BI and Dynamics 365. [emphasis mine]

The highlighted phrase indicates once again that there is an aggressive turf war going on in India about who will control the aerospace industry. Similar to the battles that occurred at NASA in the 00s and 10s, there are people within ISRO who do not wish to cede their power to an independent private industry, and are doing whatever they can to block the Modi government’s effort to create such an independent industry.

In the end, as long as Modi government stands firm, this effort will fail. Private companies will increasingly succeed, and that success will feed the transition from a government-run industry to an independent and competitive one.

Drainage out of a Martian crater

Drainage out of a Martian crater
Click for full image.

Today’s cool image to the right, rotated, cropped, reduced, and sharpened to post here, not only gives us another example of a Martian geological feature that is unique to Mars and whose origins are not yet understood, it also shows what appears to have once been a lake-filled crater that over time drained out to the east through a gap.

This picture was taken on October 14, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). The inexplicable geology is called brain terrain, and it fills the floor of the crater on the picture’s left side. The rim shows a gap, from which a meandering channel continues downhill to the east. The lake inside the crater might not have been liquid water, but ice. The channel might not have been formed by flowing water, but by a glacial flow downhill.

What makes this glacial evidence especially interesting is that it is located in a very different part of the Martian mid-latitudes.

January 3, 2023 Quick space links

Courtesy of BtB’s stringer, who trolls the web to make sure I don’t miss any important stories.

  • Astronaut Walt Cunningham has passed away
  • Cunningham only flew in space once, on Apollo 7, the first shakedown flight of the Apollo capsule in October 1968. The flight lasted ten days, had no technical problems at all, though all three astronauts caught colds. Its success paved the way for the Apollo 8 mission around the Moon two months later.

 

 

  • The trailer for the Russian sci-fi movie, The Challenge, that was partly filmed on ISS last year, has now been released
  • It is very clear that they got a lot of good footage when they were on ISS. It is a shame however that this trailer doesn’t have English subtitles, because I think it probably could make some money from American filmgoers.

China releases first update on status of Yutu-2 since September

Yutu-2's travel path through December 2022

China today released its first update since September on the status of its Yutu-2 rover on the far side of the Moon. The map on the right shows the rover’s travels through December 2022.

As of today the rover has traveled 4,774 feet total, and about 450 feet since September. The goal, as stated in April 2021, was to “move northwest toward the basalt distribution area located about 1.2 km away.” At the time the rover was only averaging about 100 feet travel per lunar day. According to these numbers, it picked up the pace in the past year, though it is unclear whether it has reached that goal.

The soft icy Martian northern lowland plains

The soft icy Martian northern lowland plains

In a cool image post last week, I noted that the near surface “ice sheets in the northern lowland plains are never … smooth, even if well protected.” The picture to the right, cropped, reduced, and sharpened to post here, provides an excellent example. It was taken on November 2, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

It is winter, and the sunlight is coming from the southwest, only 27 degrees above the horizon. The mound on the left is soft, while the depression on the upper right appears to have sand dune ripples sitting on top of a flat glacial mound. This depression may be an eroded crater (no upraised rim) or it could be a sink caused by the sublimation of the near surface ice.

Everywhere else the flat plains are stippled with small knobs.

Largest volcanic eruption in years detected on Io

Using instruments on a ground-based telescope, one scientist based at the Planetary Science Institute (PSI) in Arizona has detected the largest volcanic eruption in years on the Jupiter moon Io.

PSI Senior Scientist [Jeff] Morgenthaler has been using IoIO, located near Benson, Arizona to monitor volcanic activity on Io, since 2017. The observations show some sort of outburst nearly every year, but the largest yet was seen in the fall of 2022. Io is the innermost of Jupiter’s four large moons and is the most volcanic body in the Solar System thanks to the tidal stresses it feels from Jupiter and two of its other large satellites, Europa and Ganymede.

IoIO uses a coronagraphic technique which dims the light coming from Jupiter to enable imaging of faint gases near the very bright planet. A brightening of two of these gases, sodium and ionized sulfur, began between July and September 2022 and lasted until December 2022. The ionized sulfur, which forms a donut-like structure that encircles Jupiter and is called the Io plasma torus, was curiously not nearly as bright in this outburst as previously seen. “This could be telling us something about the composition of the volcanic activity that produced the outburst or it could be telling us that the torus is more efficient at ridding itself of material when more material is thrown into it,” Morgenthaler said.

The material released by this eruption could impact Juno during future close approaches of Jupiter.

SpaceX raises another $750 million in private investment capital

SpaceX has just completed another round of fund-raising, gaining another $750 million in private investment capital.

This additional money now means that SpaceX has raised about $10 billion in private money, most of which is being used for the development of Starship and Superheavy. When we add the $4 billion SpaceX will get from NASA for Starship, the company now has $14 billion to build this new rocket.

Rocketry went BOOM! in 2022, but in a good way

In my 2021 annual report on the global launch industry, I noted that while 2021 was a banner year for the global launch industry:

Not all is sweetness and light of course. Competition and freedom always includes risk. Some of these new companies will certainly fail. The demand for launch services might not be enough to sustain them all. And factors outside the control of anyone, such as war and further panics like the Wuhan panic, could shut them all down.

In 2022 the launch industry not only topped 2021, setting a new record for successful launches in a single year, the industry was reshaped and changed by the very factors I warned about one year ago. The Russian invasion of the Ukraine resulted in Russia losing its one remaining satellite customer from the west, OneWeb, while the challenges of rocketry caused one already successful launch company, Astra, to suspend its launch services in order to develop a more competitive rocket.

Nonetheless, 2022 remained the most successful year ever in rocketry, smashing the record for successful launches in a single year, set the previous year, by more than 33%. The graph below illustrates well the unprecedented success of 2022.

Hakuto-R successfully completes second mid-course correction

Lunar map showing Hakuto-R's landing spot
Hakuto-R’s planned landing site is in Atlas Crater.

According to Ispace, the private lunar lander company based in Japan, its Hakuto-R lander has now successfully completed second mid-course correction, and is functioning as expected on its way to the Moon.

The maneuver was carried out shortly after midnight on Jan. 2, 2023 (Japan Standard Time) and operations were managed from ispace’s mission control center located in Nihonbashi, Tokyo. This orbital control maneuver is the second maneuver to occur while the lander has been traveling to the moon. The first orbital control maneuver was completed on December 15, 2022. The second maneuver was carried out at a greater distance from Earth and lasted for a longer period than the first maneuver, verifying the company’s capability to carry out orbital maneuvers under various conditions.

As of Jan. 2, 2023, the lander has traveled approximately 1.24 million kilometers from the Earth and is scheduled to be at its farthest point of approximately 1.4 million km from the Earth by Jan. 20, 2023. Once the lander reaches its farthest point from Earth, a third orbital control maneuver may be performed, depending on its navigational status.

While Hakuto-R carries a number of commercial payloads — including Rashid, the first lunar rover built by the United Arab Emirates (UAE) — its primary goal is engineering. Ispace is using this mission to demonstrate its ability as a company to do this, in anticipation of later commercial planetary missions.

Sunspot update: The most sunspots since 2014

Time for my monthly sunspot update, based on NOAA’s monthly graph that tracks the number of sunspots on the Sun’s Earth-facing hemisphere. The newest graph, with December’s numbers added to the timeline, is below. As always, I have added some additional details to provide context.

In December the half-year pause in the ramp up to solar maximum ceased, with the Sun seeing the most sunspots since September 2014. This high activity far exceeded the predicted sunspot count for December 2023, almost doubling it. In fact, December’s sunspot count almost equaled the predicted peak for the upcoming solar maximum, which is not supposed to happen until sometime in 2025.

Cool image time! The photo to the right, rotated, cropped, reduced, and sharpened to post here, was taken on October 12. 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). Dubbed simply as a a “terrain sample” by the science team, the picture was not taken as part of any specific research project, but instead to fill a gap in the orbiter’s shooting schedule so as to maintain the camera’s proper temperature. When MRO’s science team does this, they try to pick something in the area below that might be interesting. Sometimes they succeed, but often the features in the picture are nondescript.

The white line delineates the rim of a faint and very eroded small crater. Are the depressions that are mostly concentrated just to its south and east sinks or past impact craters? I haven’t the faintest idea. The overview map below helps to answer this question, but only partly.

Philippines issues warning about Chinese rocket debris from launch

Flight path of Long March 3B
Click for full resolution image.

UPDATE: A tweet from China shows that the strap-on boosters of this rocket crashed near homes in China, though no one was hurt.

Original post:
—————–
The Philippine government issued a statement yesterday warning the public about possible debris from the December 29th launch by China of its Long March 3B rocket.

The Philippine Space Agency (PhilSA) is recommending precautionary measures related to expected unburned debris from the Long March 3B rocket scheduled for launch today between 12:33 PM and 01:10 PM Philippine time from the Xichang Satellite Launch Center in Xichang, Sichuan Province, China. Upon confirmation of planned launch dates, PhilSA immediately issued an advisory to all relevant government agencies on the estimated drop zone area and proposed the issuance of appropriate warnings on air and marine access.

Based on the Notice to Airmen (NOTAM) issued by the Civil Aviation Administration of China (CAAC) to the Civil Aviation Authority of the Philippines (CAAP), expected unburned debris, such as the rocket boosters and payload fairing, is projected to fall within a drop zone area located within the vicinity of Recto bank, approximately 137 kilometers from Ayungin Shoal and 200 kilometers from Quezon, Palawan. The unburned debris is designed to be discarded as the rocket enters outer space. While not projected to fall on land features or inhabited areas within the Philippine territory, falling debris poses danger and potential risk to ships, aircraft, fishing boats, and other vessels that will pass through the drop zone.

Though the drop zone avoided inhabited areas, it included regions where fisherman worked, and the flight path still flew over inhabited areas. The risk was extremely low, but it appears China also made no effort prior to launch to coordinate this situation with other governments, such as the Philippines. Its warning apparently arrived just before launch. Thus, there was risk that Filipino fisherman were in the drop zone at launch.

SpaceX successfully launches Israeli imaging satellite

SpaceX today successfully launched an Israeli Earth-observation satellite, using its Falcon 9 rocket.

The first stage successfully completed its eleventh flight, touching down softly at SpaceX’s facility at Vandenberg Space Force Base.

This launch completes SpaceX’s 2022 launch year, with a record 61 launches, one more than predicted by the company earlier in the year, and the most ever by a privately owned company.

The leaders in the 2022 launch race:

62 China
61 SpaceX
21 Russia
9 Rocket Lab
8 ULA

The U.S. now leads China 85 to 62, while trailing the rest of the entire world combined 94 to 85. The 85 launches for the U.S. is a new record for a single year, smashing the record of 70 launches set in 1966.

On Monday I will publish my annual full roundup of the state of global launch industry, based on the 2022 numbers.

A hint at Mars’ past climate cycles

Terraced glaciers in Martian crater
Click for full image.

Cool image time! The photo to the right, cropped to post here, was taken on October 28, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what the scientists label as a “layered feature” inside a small 4,500-foot-wide crater.

Located at 36 degrees north latitude, we are likely looking at glacial ice layers inside this crater, with each layer probably marking a different Martian climate cycle. The terraces suggest that during each growth cycle the glaciers grew less, meaning that less snow fell with each subsequent cycle. This in turn suggests a total loss of global water over time on Mars.

The overview map below gives us the wider context.

Royal Astronomical Society ends blacklisting of James Webb

That’s nice of them: The Royal Astronomical Society in Britain last week announced that it has ended its blacklisting of James Webb, the man who headed NASA during the 1960s space race, by once again permitting writers of science papers for its Monthly Notices journal to use the full name of the James Webb Space Telescope.

The Royal Astronomical Society (RAS) previously criticized NASA for not immediately addressing concerns that Webb persecuted queer employees; the NASA-led James Webb Space Telescope (JWST or Webb) that launched in December 2021 is named after him. But with new information to hand suggesting Webb played no direct role in these issues, Webb’s name can now reappear in scientific papers, the RAS stated Dec. 22.

“The RAS will now allow authors submitting scientific papers to its journals to use either ‘James Webb Space Telescope’ or the acronym ‘JWST’ to refer to the observatory,” RAS officials wrote. The major journals of the RAS include the Monthly Notices of the Royal Astronomical Society (MNRAS), one of the top astronomical journals worldwide.

The society backed off from its position after NASA published a long detailed report documenting the utter falsehood of the claim. Too bad this so-called science organization didn’t consider the evidence itself before issuing its blacklist order. One would think scientists above all would consider evidence, not undocumented slanders, as essential before condemning a person.

China’s Long March 3B rocket launches “experimental satellite”

China today successfully used its Long March 3B rocket to launch from an interior spaceport what its state-run press labeled an “experimental satellite.”

No word on where the rocket’s strap-on side boosters or first stage crashed within China.

The leaders in the 2022 launch race:

62 China
60 SpaceX
21 Russia
9 Rocket Lab
8 ULA

The U.S. still leads China 84 to 62 in the national rankings, but trails the entire world combined 94 to 84.

This launch cements for China the top spot in launches over SpaceX, since SpaceX only has one more launch planned in 2022, scheduled for just before midnight tonight.

A “What the heck?” glacier image on Mars

Glacial material on Mars
Click for full image.

Sometimes a cool image goes from bafflement to obvious as you zoom into it. The cool image to the right, cropped to post here, does the opposite. It was taken on October 11, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). I have purposely cropped it at full resolution, so that its eroded glacier nature is most obvious.

The cracks and hollows are likely caused by the sublimation of the near surface underground ice, breaking upward so that the protective surface layer of debris and dust collapses at some points, and cracks at others.

The overview map below further confirms the likelihood that we are looking at glacial features, but when we also zoom out from this close-up we discover things are not so easily explained.

Using reflected light from Jupiter to photograph Ganymede’s night side

Ganymede as seen in the reflected light of Jupiter
Click for full image.

During Juno’s June 7, 2021 close fly-by of Ganymede, scientists used its instruments to obtain the first good image of a part of this Jupiter moon. What made the achievement especially amazing was that the area photographed was only lit by the reflected light from Jupiter, the equivalent of its “earthshine.” From the paper’s abstract:

On 7 June 2021, the Juno spacecraft flew within about 1,000 km of the surface of Jupiter’s largest moon, Ganymede. The Mission used their sensitive navigation camera to photograph the moon’s dark side where it was lit only by scattered sunlight from Jupiter. This new imaging approach revealed multiple surface features, including a patchwork of different surface textures (such as grooved terrain), several craters, and ejecta deposits. These features had not been visible in images collected by previous spacecraft.

The picture to the right is from figure 2 of the paper, cropped and reduced to post here. It shows a region on Ganymede that in the earlier images had shown few details because the lighting was poor and thus features were not easily discerned (as can be seen by the inset in the lower right). In the new picture, the only light was reflected from Jupiter, and its low angle brings out the surface topography.

Russian investigators conclude leak on Soyuz caused by external impact

ISS as of November 28, 2022
ISS after November 28, 2022 docking of unmanned Dragon freighter.
MS-22 is the Soyuz capsule that is leaking.

The Russian investigators yesterday concluded that the coolant leak on the Soyuz capsule docked to ISS was caused by an external impact, either by a meteroid or a small piece of space junk.

A decision on whether this capsule is still usable for manned flight will be made sometime in January. If not, Russia will move up the launch of the next Soyuz to ISS one month from March to February, but launch it empty. If so, managers will leave the schedule as is.

If the engineers determine the capsule is not flightworthy, it will mean however that until February, ISS is short one lifeboat. At present there are two Dragon capsules docked to ISS, one manned and one cargo. Both return to Earth with a habitable interior, but the cargo capsule is not intended for manned flight. In an emergency however it might be possible to use it.

This situation suggests that NASA should pay to get SpaceX to upgrade the cargo Dragons so that they could always be used as an emergency lifeboat.

SpaceX launches 54 more Starlink satellites

SpaceX early today completed its 60th successful launch in 2022, putting 54 Starlink satellites into orbit using its Falcon 9 rocket.

This achievement matches a prediction Elon Musk made early in 2022. More significant, except for two years (1965 and 1966), SpaceX completed more launches in 2022 than the United States achieved each year since Sputnik. And it did it not as a nation, but as a private company, for profit.

SpaceX’s achievement this year also allowed the U.S. to smash its own record for annual launches.

The first stage successfully completed its 11th flight, landing on a drone ship in the Atlantic.

The leaders in the 2022 space race:

61 China
60 SpaceX
21 Russia
9 Rocket Lab
8 ULA

The U.S. now leads China 84 to 61 in the national rankings, but trails the entire world combined 93 to 84.

Only one more launch, by SpaceX, is publicly scheduled for 2022.

Today’s blacklisted American: Black scientist blacklisted for doing good research

Oluseyi Hakeem, blacklisted
Hakeem Oluseyi, Space Science Education Lead
for NASA’s Science Mission Directorate

They’re coming for you next: Today’s blacklist column describes an effort to not only cancel from history the man who led NASA for almost the entire 1960s space race, but to also blackball a scientist for doing good research that proved the campaign was not based on any facts.

Shortly before the launch of the James Webb Space Telescope last year, a petition was instigated to get it renamed because of accusations that Webb had persecuted homosexuals during his term as NASA administrator in the 1960s. As is now typical of our modern bankrupt intellectual class, as soon as this petition was issued more than 1,700 people signed it, all accepting at face value its accusations against Webb without any further research.

One scientist, who happened to be black, took a more detailed look at those accusations however and found them to be spurious. As Hakeem Oluseyi wrote:

Finding Martian glaciers from orbit

Glacier flow on Mars
Click for full image.

Today’s cool image is a great example of the surprises one can find by exploring the archive of the high resolution pictures that Mars Reconnaissance Orbiter (MRO) has produced since it arrived in Mars orbit back in 2006. The picture to the right, rotated, cropped, and reduced to post here, was taken by MRO’s high resolution camera back on May 4, 2017. I only found it because I had picked out a October 24, 2022 high resolution image that covered a different area of this same flow feature just to the north east. In trying to understand that 2022 picture I dug to see other images had been taken around it, and found the earlier 2017 photo that was even more interesting.

Neither however really covered the entire feature, making it difficult to understand its full nature. I therefore searched the archive of MRO’s context camera, which has imaged the entire planet with less resolution but covering a much wider area per picture. The context camera picture below captures the full nature of this feature.

SpaceX has about 100 Starlink terminals working in Iran

Though the Iranian government opposes their use, according to a tweet by Elon Musk SpaceX now has almost 100 Starlink terminals working in Iran.

Elon Musk announced that SpaceX has almost 100 Starlink terminals active in Iran. SpaceX activated Starlink services in Iran in September, supporting the United States’ stance on providing internet freedom and free flow of information to Iranians.

Unlike Ukraine, SpaceX does not have the cooperation of the Iranian government to expand Starlink services in the country. In Ukraine, President Volodymyr Zlenskyy and the Minister of digital transformation Mykhailo Feorov have actively supports Starlink connection during the war with Russia.

In contrast, the Iranian government is actively trying to limit its citizens’ internet access. The United States government has taken a stance against the Iranian government’s decision regarding internet access for its people.

SpaceX has routinely cooperated with foreign governments before selling terminals, likely because to do otherwise would get it in trouble with the U.S. State Department. In this case however the State Department appears to have approved this action, and SpaceX then made it happen.

China launches Earth observation satellite

China today successfully launched a classified Earth observation satellite using its Long March 4B rocket.

As the launch was from an interior spaceport, the rocket’s lower stages landed somewhere in the interior of China.

The leaders in the 2022 launch race:

61 China
59 SpaceX
21 Russia
9 Rocket Lab
8 ULA

The U.S. still leads China 83 to 61 in the national rankings, but trails the entire world combined 93 to 83.

At the moment, the only known remaining launches in 2022 are two SpaceX Falcon 9 launches. However, China routinely launches a lot in the November/December timeframe, so we should not be surprised if they complete one or two launches as well in the next few days.

The location is at 38 degrees north latitude, in the Martian northern lowland plains. At this latitude in these plains the geological features seen in high resolution pictures almost always invoke near surface ice, including processes that disturb that underground ice layer.

This picture is no different. Not only does it appear that a glacier is flowing down from the top of east-west ridge, the middle mound includes a crater with its southeast rim gone and appears filled with material that suggests ice.

A long-armed galaxy

Galaxy with long and faint tidal streams
Click for full image.

Cool image time! The photo to the right, cropped, enhanced, and reduced to post here, was taken by the Hubble Space Telescope as part of a survey of peculiar looking galaxies.

The peculiar spiral galaxy ESO 415-19, which lies around 450 million light-years away, stretches lazily across this image from the NASA/ESA Hubble Space Telescope. While the centre of this object resembles a regular spiral galaxy, long streams of stars stretch out from the galactic core like bizarrely elongated spiral arms. These are tidal streams caused by some chance interaction in the galaxy’s past, and give ESO 415-19 a distinctly peculiar appearance.

ESO 415-19’s peculiarity made it a great target for Hubble. This observation comes from an ongoing campaign to explore the Arp Atlas of Peculiar Galaxies, a menagerie of some of the weirdest and most wonderful galaxies that the Universe has to offer. These galaxies range from bizarre lonesome galaxies to spectacularly interacting galaxy pairs, triplets, and even quintets. These space oddities are spread throughout the night sky, which means that Hubble can spare a moment to observe them as it moves between other observational targets.

I have intentionally brightened the galaxy to make the two faint two tidal streams more obvious. That they are so faint compared to the galaxy itself is in itself a mystery.

Attack that injured Rogozin in the Ukraine also killed two

Dmitry Rogozin playing make-believe soldier
recently in the Ukraine

More details have now emerged about the explosion that injured former Roscosmos chief Dmitry Rogozin, including the fact that the attack, in Ukrainian occupied territory in Donetsk, also killed two.

The former head of Russia’s space agency was wounded when an artillery shell exploded as he celebrated his birthday in a hotel near the front line in Ukraine. Dmitry Rogozin, a flamboyant Russian politician who was once a deputy prime minister, was reportedly hit in the buttocks, head and back by shrapnel.

Two people were killed in the attack and several others were wounded, authorities in Donetsk said on Thursday, and Mr Rogozin said he was due to be operated on. Russian state news channel Rossiya 24 TV said the former space chief was celebrating his 59th birthday at the Shesh-Besh hotel and restaurant with several other separatist officials.

But Mr Rogozin insisted the incident took place during a “work meeting”.

Russian investigators think the shell came from a French-made Caesar self-propelled howitzer.

The criticism of Rogozin concerning this story has been quite ugly.

“A party 10 kilometres away from the front line with the Ceasar’s range of 40 kilometres? I would reprimand him for being childish,” [wrote Yuri Podolyaka, a prominent pro-Kremlin blogger.] “Two people have died in that restaurant, which, I think, is on his conscience.”

Rogozin’s path has been steadily downward since he was deputy prime minister of Russia’s defense department from 2011 to 2018. First he was demoted to head of Roscosmos, where he ended up losing Russia more than a half billion in income by his cancellation of the launch contract with OneWeb. Worse, that cancellation, and Rogozin’s confiscation of 36 OneWeb satellites, ended any chance of Russia getting any international business for years to come.

These actions caused him to be fired from Roscosmos in July, and shipped to the Ukraine (the modern equivalent of Siberia) to act as an envoy in the Russian-occupied territories. Once there, he did nothing to enhance his reputation. By holding this very public birthday party, at a public place so close to the front lines, was almost guaranteeing he and his party would be attacked.

I wish he quickly recovers from his injuries, but I also think Putin would be foolish to give this guy any further positions of authority.

Crater at the edge of the Martian south pole ice cap

Oblique view of south pole crater
Click for full image.

Overview map

Cool image time! The oblique panorama above, reduced and sharpened to post here, was created from an image taken on May 19, 2022 by the European orbiter Mars Express. Its location on edge of the layered deposits of ice and dust that form most of the Martian southern ice cap is indicated by the white rectangle on the overview map to the right. From the press release:

While it may look like a winter wonderland, it was southern hemisphere spring at the time and ice was starting to retreat. Dark dunes are peeking through the frost and elevated terrain appears ice-free.

Two large impact craters draw the eye, their interiors striped with alternating layers of water-ice and fine sediments. These ‘polar layered deposits’ are also exposed in exquisite detail in the rusty red ridge that connects the two craters.

The scattered white patches are either water frost, or the winter mantle of dry ice, both now sublimating away with the coming of spring.

The black line on the overview map indicates the extent of the layered deposits, and suggest that the ridgeline is not considered part of that ice cap layer, in contradiction to the press release language above.

Which is it? I would guess the answer is simply the uncertainty of science. Some scientists took a look here and decided the ridge was actually a base layer sticking up through the layered deposits. The European scientists who took this picture have instead concluded, based on the image, that the ridge is part of the layer deposits.

Newly passed Senate bill requires consultation between industry and government on space junk

Though the bill still needs to be passed by the House, a just passed Senate bill requires consultation between industry and government on space junk, short circuiting recent attempts at the FCC as well as in the House to impose arbitrary government regulations.

You can read the Senate bill here [pdf].

The final result will still be government regulation on the lifespan and final deposition of any object placed in orbit, from nanosats to large manned space stations, but unlike the earlier FCC proposal and House bill, NASA and other government agencies will have to obtain feedback from the commercial space industry before such regulations are imposed.

Sounds great, eh? In truth, this bill in the end still gives full power to the federal government to control the launching of future spacecraft of all sizes. It also leaves the details entirely up to the bureaucracy. If passed Congress would cede its regulatory power to unelected bureaucrats in the executive branch.

The requirement that industry consultation occur simply means that the initial regulations will likely make some sense. Beyond that however the power it bequeaths to the federal bureaucracy in NASA, FAA, FCC, and other agencies will in the long run be still abused.

The need for the establishment of an independent space-faring society, free from odious Earthbound regulation, continues to grow.
