Glaciers in the Phlegra mountains
Click for full image.

Cool image time! The photo to the right, cropped to post here, is just one of the many hundreds taken by the high resolution camera on Mars Reconnaissance Orbiter (MRO) as well as Europe’s Mars Express orbiter showing the thick icy glacial flows that surround practically every mountain or hill in the Phlegra mountains of Mars.

This picture was taken on November 3, 2021, and shows the eroding foot of an eroding glacial flow coming down from a small hill in a southeastern part of these mountains dubbed Phlegra Dorsa. The downward grade is to the north.

At 30 degrees north latitude it is not surprising these glacial flows are eroding, as they are at the southernmost limit of the mid-latitudes bands where such glaciers are found. Closer to the equator scientists have yet to find much evidence of ice.

The repeating arcs at the foot of this glacier suggest that it pushed downward in cycles, with each later cycle traveling a shorter distance. This supposition makes sense, considering scientists think the ebb and flow of these Martian glaciers has been determined by the cyclical changes in the planet’s rotational tilt.

The overview map below not only gives the context, it shows this location relative to the candidate landing sites for SpaceX’s Starship spacecraft.

China’s plans to dominate space revealed in a new Chinese government white paper

11:53 am

China's 2022 white paper on space

The new colonial movement: The Chinese government today released a white paper summarizing in broad terms what it has accomplished in space over the past five years and what it intends to do in the next five years.

If this white paper is ignored by western governments, the ramifications to human freedom and civilization in space will be profound, and quite likely tragic.

You can read the English text of the white paper here.

The paper makes clear China’s considerable successes and advancements in the aerospace sector since 2016. It ramped up its manned program with the launch of two prototype space modules followed by the on-going assembly of its fullsize station. It has successfully landed probes on the Moon and Mars, and brought back samples from the former. It is presently upgrading or replacing its older rockets. It has launched a full constellation of Landsat-type Earth-resource satellites. It has expanded its satellite communications and broadcasting capabilities. It has completed its 30-satellite GPS-type constellation.

And that’s only a short summary.

The white paper then outlines China’s ambitious plans for the next five years. Three areas are of greatest importance.

Will SpaceX recover Superheavy on land or at sea?

10:36 am

A recent job posting by SpaceX suggests it is still exploring its land or sea landing options for its Superheavy booster.

The job posting said that the company was “seeking a Marine Engineer to support … [its] current fleet of rocket and spacecraft recovery vessels, as well as the development of marine recovery systems for the Starship program.”

The article at the link outlines the many recovery options SpaceX has for Superheavy. The author notes that company’s recent focus has been to bring Superheavy back to its launchpad for quick relaunch. This new job posting suggests SpaceX has not finalized these plans.

First, it might be possible that SpaceX is merely preparing for the potential recovery of debris or intact, floating ships or boosters after intentionally expending them on early orbital Starship test flights. Second, SpaceX might have plans to strip an oil rig or two – without fully converting them into launch pads – and then use those rigs as landing platforms designed to remain at sea indefinitely. Those platforms might then transfer landed ships or boosters to smaller support ships tasked with returning them to dry land. Third and arguably most likely, SpaceX might be exploring the possible benefits of landing Super Heavy boosters at sea.

The author goes on to analyze the pros and cons for returning Superheavy to land, as well as the issues landing it at sea. Based on this analysis, SpaceX is probably planning to have Superheavy to return to land for the near future, even as it explores the sea option because it uses so much less fuel.

India’s new Vikram lunar lander almost ready for launch

9:41 am

The new colonial movement: India’s new Vikram lunar lander, planned for launch later this year on Chandrayaan-3, is now undergoing final tests and assembly.

All payloads for tracking the lunar activity, the alpha-particle X-ray spectrometer and the ChaSTE — the lone instrument to touch the lunar surface to perform thermal measurements of lunar high-latitude regions — and others are being integrated with the rover. These are getting ready for tests and launch later this year,” said Kiran Kumar, who is currently the chairman of the Physical Research Laboratory (PRL) Council and a member of the Apex Science Board of the ISRO.

A launch date has not yet been set. Moreover, for this mission to fly India has got to get its rocket program flying again. It has been essentially shut down for two years because of its panic over the Wuhan virus.

SpaceX aiming to launch 52 times in 2022

9:31 am

According to NASA officials, SpaceX is hoping to complete as many as 52 launches in 2022, a pace of one launch per week.

The impressive figure was given during a virtual meeting of NASA’s Aerospace Safety Advisory Panel, or ASAP, which gives guidance to the space agency on how to maintain safety within its biggest programs. “NASA and SpaceX will have to be watchful during 2022 that they’re not victims of their success,” Sandy Magnus, a former NASA astronaut and member of the panel, said during the meeting. “There’s an ambitious 52-launch manifest for SpaceX over the course of the year. And that’s an incredible pace.”

Based on other sources, I had previously estimated a SpaceX manifest for ’22 to be 40 launches. That this new higher number comes from NASA’s corrupt safety panel, and was touted as a reason to raise questions about SpaceX, makes me suspicious of it.

Still, a launch pace by SpaceX of one launch per week is wholly possible. For one thing, the company needs to get a lot of Starlink satellites into orbit as quickly as possible. With its development of Starship blocked by government interference, it might have decided to up the pace of launches using Falcon 9.

Furthermore, because most of the rocket is reused, SpaceX has a far greater launch capacity. For every Falcon 9 it builds it gets ten or more launches from its first stage. This means SpaceX does not have to build as much to maintain a high launch pace.

As for the safety panel’s fears about such a pace, who cares? That safety panel has been consistently wrong about everything it has said about SpaceX and commercial space now for almost a decade. It is very likely wrong now. In a more rational world, NASA would have shut it down two years ago for doing such a bad job. Sadly, we no longer live in a rational world.

A Chinese space plane?

9:17 am

One of China’s pseudo-companies, named Space Transportation, has now announced that it plans to build and launch a fully reusable suborbital space plane to be used for both space tourism and point-to-point transportation, with the first flight targeted for ’24.

Space Transportation announced last August that it had raised $46.3 million for its hypersonic space plane plans, and the company has recently been conducting a number of tests of its Tianxing 1 and Tianxing 2 vehicles. A 10th flight test was conducted on Jan. 23, followed by another test in collaboration with a combustion laboratory belonging to Tsinghua University.

Details about these test flight activities have been limited, possibly due to the sensitive nature of hypersonic-related technologies.

The China Aerospace Science and Technology Corporation (CASC), China’s main space contractor, in 2020 and 2021 conducted highly secretive launch tests of suborbital and orbital vehicles from the Jiuquan Satellite Launch Center as part of a space plane development program. [emphasis mine]

It could very well be that the so-called Chinese super duper hypersonic military test flights that various anonymous and public officials in the U.S. military have claimed took place in the past few years were merely these ground tests by Space Transportation, ginned up to appear more dangerous and threatening.

If so, this fear-mongering by the American military community is somewhat shameful and dishonest, and in the long run is not the right way to go about its business. Their exaggeration of the threat leads to skepticism, which actually makes it more difficult to get their own hypersonic program funded.

Today’s story however is important. We must recognize that this attempt by China to apply hypersonic technology to commercial transportation applications is quite smart, and can eventually be dangerous to us. It will help stimulate development, which can then be applied to military applications.

It is also one of the rare times China has taken the lead in innovation. Except for one British rocket startup, as far as I know no western company is trying to develop hypersonic concepts for commercial purposes.

ABL test explosion to delay 1st launch three months

2:36 pm

Capitalism in space: An explosion last week during a static fire test of the upper stage engine of ABL Space’s RS1 rocket test explosion will delay that rocket’s first launch by three months, according to company officials.

The incident took place in the seventh in a series of hot-fire tests of the stage in Mojave. The overall test campaign started in December with a series of fill-and-drain, cold flow and ignition tests, followed by the hot-fire tests. Piemont said that, at the time of the anomaly, at least five more tests were planned before the company completed the test campaign.

That upper stage was being tested ahead of the first RS1 launch from Kodiak Island, Alaska. “After some final engine design changes were identified last summer, we set an aggressive schedule to try to launch by the end of 2021,” Piemont said. “Our schedule slipped a bit in past few months, but our programs were converging towards a launch from Kodiak in February.”

It now appears the RS1 will not launch any earlier than May.

Scientists: Liquid surface water might have existed on Mars as recently as 2.3 billion years ago

10:00 am

Map showing locations of salt deposits
Click for full image.

Using orbital data from Mars Reconnaissance Orbiter (MRO), scientists have found salt deposits on Mars where nearby crater counts suggest that the salt water that once held these deposits could have evaporated away as recently as 2.3 billion years ago.

Using [MRO’s] cameras to create digital elevation maps, Leask and Ehlmann found that many of the salts were in depressions – once home to shallow ponds – on gently sloping volcanic plains. The scientists also found winding, dry channels nearby – former streams that once fed surface runoff (from the occasional melting of ice or permafrost) into these ponds. Crater counting and evidence of salts on top of volcanic terrain allowed them to date the deposits.

Past data has suggested that if liquid surface water had existed on Mars, it was gone by three billion years ago.

You can read the scientists’ research paper here.. The maps to the right, figure two from the paper, shows the locations of discovered salt deposits, almost all of which are in the Martian southern cratered highlands of Mars.

Is there uncertainty in these results? My regular readers know that the answer is of course yes. The biggest problem for these Mars researchers is that, despite the surface evidence that liquid water should have once flowed on the surface of Mars, no scientist has yet come up with a satisfactory model of Mars’ past climate that would have made that possible. The planet was either too cold or had too thin an atmosphere, based on other data. And getting it warmer or with a thicker atmosphere involves inventing any number of scenarios that are all questionable, based on what is presently known.

There is also the increasing evidence that glaciers of ice, not water, might have carved those winding, dry channels. If so, many of the assumptions that liquid water existed might simply be wrong, or incomplete. The scientists who wrote this report recognize this importance of ice on Mars, and note in their abstract that

…we think that the water source came from surface runoff, rather than deep groundwater welling up to the surface. The small amounts of water required are most likely from occasional melting of ice.

As always, more data is needed, with the most useful data that will clarify these conclusions being that gathered by future colonists on the surface of Mars itself.

Russia schedules July 23rd for launch of its first unmanned lunar lander in decades

9:37 am

The new colonial movement: The Russia design bureau that is building Luna-25, Russia’s first unmanned lunar lander since the 1970s, has announced that it is targeting July 23, 2022 for launch.

The lunar mission will be launched atop a Soyuz-2.1b carrier rocket with a Fregat booster from the Vostochny spaceport in the Russian Far East. Under the lunar project, the Luna-25 automatic station will be launched for studies in the area of the lunar south pole. The lander is set to touch down in the area of the Boguslawsky crater.

Boguslawsky crater is about 125 miles from the nearest known permanently shadowed craters, and about 250 miles north of the south pole. It is thus not landing in what is presently thought to be the most valuable real estate on the Moon because of the possible presence of water ice, though there might be other resources at Boguslawsky that interest the Russians.

New Arianespace Vega-C rocket being prepared for first launch in April

9:22 am

Engineers in French Guiana are now preparing all the components of the first Vega-C rocket, built by the Italian company Avio, for its first launch in April.

Vega-C is an upgraded version of the Vega rocket and is currently set to launch no earlier than April 2022. The rocket will feature improved first and second stage solid rocket motors, an upgraded liquid-fueled AVUM+ upper stage, and usher in an era of propulsion system commonality between the Vega and Ariane rocket lines.

At the moment they are modifying the Vega launchpad and building a new mission control center. Once completed in March they will stack the rocket.

Vega-C, like its predecessor, is powered by solid rockets, which Avio believes can be competitive with reusable rockets, at least for the next decade or so. Arianespace also hopes to lower costs by using the exact same solid rocket boosters on both Vega-C and its new Ariane 6 rocket. Vega-C’s first stage, using a P120C solid rocket motor, is also used as side boosters on Ariane 6.

China tests space junk removal robot in geosynchronous orbit

9:08 am

China has apparently used a space junk removal robot to tug a defunct Chinese satellite out of geosynchronous orbit, thus opening that slot for future satellites.

Ground tracking by ExoAnalytic Solutions found that the robot, dubbed SJ-21, apparently docked with the defunct satellite on January 22nd. Since then:

In an email to Breaking Defense this afternoon, Flewelling [of ExoAnalytic] said the latest tracking data gathered earlier today from ExoAnalytic’s telescopes show the SJ-21 separating from the Compass G2, leaving the latter in the eccentric “super-graveyard drift orbit.” SJ-21 now has moved back to a near-GEO orbit.

The orbit places the defunct satellite in an orbit above the geosynchronous orbit satellites use, but in an orbit that is not typical.

This work is comparable to what the Japanese/American company Astroscale is presently testing in low Earth orbit, though it appears far more sophisticated. In fact, based on what SJ-21 has done so far, it appears China is far ahead of everyone else in developing in-orbit robotic servicing capabilities.

Astroscale stops orbital capture demo after detecting “anomalous spacecraft conditions”

5:22 pm

Capitalism in space: Astroscale has halted an ambitious demonstration in-orbit of its magnetic capture technology when its engineers detected “anomalous spacecraft conditions.”

The demo involved a client satellite (posing as space junk) and a separate robot. Both were equipped with Astroscale’s magnetic capture device. A test in August had successfully separated the two units by a small distance, and then demonstrated that the magnetic capture device could grab the client satellite.

In the on-going but paused demo the robot was to separate, fly a distance away, and then use its autonomous programming to rendezvous with the client and then recapture it again. It successfully separated but that’s when the anomalies were detected. Engineers are now reviewing the data to see if they correct these issues and then proceed with the rest of the demo.

If successful Astroscale would demonstrate that their magnetic capture system works, thus giving them a strong selling point to have satellite companies buy it and install it on their satellites. Then, when the satellite was no longer needed Astroscale could send a robot up, capture it, and then de-orbit it safely.

Oman signs deal with companies to build and launch its first probe beyond Earth orbit

1:33 pm

Capitalism in space: The Sultanate of Oman has finalized an agreement to have the Polish company SatRevolution build its first probe to go beyond Earth orbit and have Virgin Orbit launch it.

The target beyond Earth and the missions specific goals has not yet been determined, though the goal is to launch it before the end of ’24.

This agreement is in a addition to an earlier agreement by the same entities to build and launch Oman’s first satellite, set to launch from an airport runway in Cornwall, Great Britain, sometime later this year.

What this agreement tells us that there is money to be made building spacecraft and launching them. Oman wants to have its own space program, like its neighbor the United Arab Emirates (UAE), but like the UAE it does not have the aerospace industry to make that possible. The solution? Hire the skillsets of private companies, in this case from the U.S. and Poland.

Stratolaunch wins Air Force hypersonic research contract

1:17 pm

Capitalism in space: Stratolaunch today announced [pdf] that is has been awarded by the Air Force contract to study whether its Roc aircraft carrier and Talon-A research craft will be useful in test hypersonic weapons and spacecraft.

Stratolaunch, LLC is pleased to announce a research contract with the U.S. Air Force Research Laboratory (AFRL).

Stratolaunch, under partnership with Booz Allen Hamilton, is on contract with AFRL to examine and assess the feasibility of hypersonic flight tests of a wide range of Air Force experiments and payloads on a frequent and routine basis.

Stratolaunch supports national security objectives for hypersonic offensive and defensive weapons development through the design, manufacture, and operation of a fleet of reusable hypersonic aerospace vehicles air-launched from its globally deployable carrier aircraft, Roc. The company plans to augment existing Department of Defense flight test resources through affordable, commercially contracted, rapid-turnaround hypersonic flight testing for the Department of Defense and its prime contractor partners.

This contract is not to do actual tests, but to study whether Stratolaunch’s equipment can make hypersonic tests easier, cheaper, and more frequent, as the company promises.

Eta Carinae: The star that proved Hubble was fixed

1:02 pm

The Space Telescope Science Institute, which operates both the Hubble Space Telescope and the James Webb Space Telescope, today released a wonderful short video summarizing in images the decades of knowledge that Hubble has gleaned of the massive star Eta Carinae.

I have embedded that video below the fold. What makes Eta Carinae special is that when Hubble was pointed at it shortly after the first repair mission in 1993, that photo proved without a doubt that the telescope’s vision had been fixed. More important, the photo proved that Hubble was going to routinely show us things never before seen. In this case, we got our first sharp and unambiguous view of a massive star exploding.

Isar Aerospace wins $11.3 million in EU innovation competition

9:05 am

Capitalism in space: The German rocket startup company Isar Aerospace has won the first place $11.3 million prize in the European Innovation Council Horizon Prize in the category of low-cost rockets.

Isar was one of three finalists for the prize announced earlier this month by the European Commission, along with another German small launch vehicle developer, Rocket Factory Augsburg, and Spanish company Payload Aerospace, which is working on a reusable small launcher. Those three came from an initial pool or more than 15 applicants, Breton said at a ceremony during the conference to announce the winner.

Isar hopes to launch its rocket, called Spectrum, late this year.

Whether this contest marks the beginning of an open and competitive launch industry in Europe remains unclear. Apparently the EU is thinking of creating what it calls the “European Space Launcher Alliance,” which — from the vague descriptions of it as well as the reservations expressed by Isar officials — might force independent companies to cater their actions to the needs of the larger rocket companies, like Airbus and ArianeGroup. This quote suggests the thinking of those larger companies:

“We understand how important it is for Europe to grab and keep leadership,” said Morena Bernardini, vice president of strategy at ArianeGroup. “This is possible only if industry is pushing in one direction.” [emphasis mine]

If I was a new startup, the highlighted words from this powerful established big space company would worry me enormously. Who decides what that “one direction” is? And what if different companies want to approach rocketry differently?

Lucy update: cause of solar array issue identified

8:49 am

Lucy solar panel graphic

According to the principal scientist for the Lucy asteroid mission, engineers think they have identified what caused one of Lucy’s two fanlike solar arrays to fail to deploy completely.

The +Y array, rather than unfurling a full 360 degrees, instead went 347 degrees. In that configuration, the spacecraft is still generating more than 90% of its expected power. “Power is not an issue for the spacecraft, nor will it be through the entire mission if we have to fly it like it is.”

The arrays unfurl when a motor pulls on a lanyard, swinging one end of the array around and into place. Levison said that the most likely reason the array did not latch is that, for some reason, there was a loss of tension in the lanyard during deployment. That caused it to fall off a spool and wrap around the motor shaft. About 75 centimeters of lanyard remains to be pulled in.

It appears they in April will turn on the array’s motor to try to pull the lanyard in that last little bit. If that doesn’t work, they will then simply leave things as they are, as it appears the array is open enough to give them sufficient power for their mission.

There are risks to that course, however. Because the array is not latched open, it could begin to close, and thus result in less power to the spacecraft. Furthermore, its unlatched state appears to make some planned engine burns too risky.

Update on the video game Pioneer 2140CC & its February 1st Kickstarter launch

9:39 pm

With less than a week before the start of the Kickstarter campaign on February 1, 2022 to raise at least $73,000 to pay for producing the video game Pioneer 2140CC (based on my science fiction book, Pioneer), Aaron Jenkin, the game’s producer, tonight sent out an update to the subscribers of the Kickstarter newsletter.

Besides describing the growing interest from our potential audience as well as his recent successes at marketing, Aaron’s the big announcement was the release of the game’s trailer, embedded below:

I was personally quite impressed with this trailer, which Aaron tells me he created himself. It captures perfectly what I tried to say in the book, and does so while adding intelligently the necessary game elements that any video game must have. Pioneer is about the human spirit, faced with the actual dangers that future space explorers will face, not the typical science fiction faux aliens or artificial cartoon character conflicts that are all too common in many sci-fi movies. Space is deadly and alien, and it will be the noblest achievement of humanity to make it possible for humans to live and work there.

If you are interested in supporting the game (as well as buying it when it is published), go to PioneerSpaceGame.com and subscribe to the newsletter for future updates counting down to the February 1st launch.

You might also want to read Pioneer first. It won’t necessarily help you play the game, but it will put you in the right mindset.

Planetary scientists fight back: “Pluto is a planet!”

6:04 pm

A group of eminent and active planetary scientists have just published a new peer-reviewed paper documenting how moons and asteroids were routinely referred to as planets from Galileo until 2006 when a very small number of scientists at an International Astronomical Union (IAU) meeting decided arbitrarily that the definition must be changed.

That IAU definition, which required an object to have a solar orbit and the vague ability of the object to clear that orbit, somehow made Pluto a non-planet. It has also never been accepted by planetary scientists, who consider it inconsistent, vague, and useless in their research as well as in teaching students about planetary science. I know this attitude is real because of what planetary scientists have told me consistently in many interviews since 2006.

The new paper appears to be part of a new aggressive campaign by planetary scientists to get that IAU definition dumped, and replace it with the definition planetary scientists have been using forever, which is that if the object is large enough for gravity to shape it into a spherical shape, it is a planet. This is still the definition they routinely use when discussing large moons like the Moon or the large Galilean moons of Jupiter or the larger moons of Saturn or Pluto itself.

It also appears, based on information at the link, that this campaign is beginning to make headway. To that I say, Hallelajuh!

Mars’ youngest lava flow

Mars' youngest lava flow
Click for full image.

Today’s cool image is in some ways another version of my last cool image yesterday. Both are in Mars’s volcano country. Both show what appears to be a lava flow.

Yesterday’s image showed the leftover evidence of a confined flow of lava running in a meandering pattern like a river, and was somewhat distant from the biggest nearby volcanoes. Today’s cool image, to the right and rotated, cropped, and reduced to post here, is instead located smack dab on the inside of what is thought to be Mars’ youngest major lava event, the Athabasca flood lava plain, and in fact is near its outlet, when about 600 million years ago it belched out enough lava in just a matter of a few weeks to cover an area about the size of Great Britain.

The overview map below illustrates this.

Ukrainian rocket company signs deal with Portuguese spaceport organization

10:43 am

Capitalism in space: Ukrainian startup rocket company Promin Aerospace has signed an agreement with the Atlantic Spaceport Consortium (ASC), a Portugal organization that is aimed at building launch facilities on Portuguese-controlled islands in the Atlantic.

Promin has raised $500K for what it claims will be “the smallest solid rocket capable of launching a payload into orbit.” ASC meanwhile is presently building a suborbital launch site in the Azores.

How much of this is real is entirely unknown. The reality of both appear to me to be somewhat nebulous. Nonetheless, if successful the partnership will put another new cheap orbital rocket as well as another spaceport on the map.

Axiom awards construction contract for building Houston space station factory

9:51 am

Capitalism in space: Axiom has awarded its first construction contract for building its space station factory at a Houston industrial park dubbed Spaceport Houston.

Phase I of the Houston Spaceport architecture and engineering design contract was awarded to Jacobs by Axiom Space. This 100,000 sq ft facility will be developed on a 400 acre-site, located within Ellington Airport, at the heart of Space City. Axiom Space, the privately funded space infrastructure developer intends to use this new spaceport to achieve its goal of assembling the first commercial international space station and providing access to low Earth orbit.

The choice by Axiom of Houston for this facility is, at first glance, somewhat puzzling. Once built here Axiom’s large station modules and equipment will then have to be transported to some launch facility, likely Kennedy in Florida. Wouldn’t it have made more sense to build them in Florida, close to where they will be launched?

The explanation lies in politics. Axiom’s management has many close ties to NASA and the Johnson Space Center. Furthermore, Axiom’s first modules will be docked to ISS, run by Johnson. Building in Houston will give Axiom brownie points with these government entities, which will in turn grease the wheels for anything Axiom needs to do at ISS.

Strong opposition to new proposed regulation by federal safety board

9:41 am

We’re here to help you! Both the FAA and the rocket industry, led by SpaceX and Blue Origin, have issued detailed written opposition to a proposal by the National Transportation Safety Board (NTSB) that it be placed in charge of all future space accident investigations.

The regulations would require companies conducting a launch or reentry under an FAA license or experimental permit to immediately notify the NTSB in the event of a mishap. The NTSB would conduct an investigation to determine the probable cause and provide recommendations to avoid similar events in the future.

The opposition notes that this will merely duplicate what the industry and the FAA already do. The rocket industry also noted that the NTSB’s present investigation responsibilities are aimed at helping the mature airline industry, not “a nascent industrial sector that is still in development, and is appropriately regulated as such.”

It appears that there is also opposition in the halls of Congress, as two congressmen have expressed their own opposition.

Without doubt the NTSB’s action here has been encouraged by the Biden administration. Democrats always want more regulation to enhance the power of government. Since Biden and his Democratic Party handlers took over, the federal bureaucracy’s effort to regulate and hinder space activities has definitely increased, such as its efforts to block SpaceX’s Starship development at Boca Chica.

Had the NTSB tried to propose this during the Trump administration it would have been quickly quashed. For example, when NOAA tried to claim it had the right to regulate all orbital photography and the Trump administration told them no, in no uncertain terms.

Falcon 9 upper stage to impact Moon

9:18 am

A Falcon 9 upper stage launched in February 2015 is apparently now on a course to impact the Moon this coming March.

According to Bill Gray, who writes the widely used Project Pluto software to track near-Earth objects, asteroids, minor planets, and comets, such an impact could come in March.

Earlier this month, Gray put out a call for amateur and professional astronomers to make additional observations of the stage, which appears to be tumbling through space. With this new data, Gray now believes that the Falcon 9’s upper stage will very likely impact the far side of the Moon, near the equator, on March 4.

Grey’s call out for more measurements is because there are uncertainties about this prediction. To prepare for observations of the impact by a variety of lunar orbiters, researchers need better data.

NM legislators propose sales tax on Virgin Galactic tourist flights

9:08 am

We’re here to help you: A bi-partisan proposal by two New Mexico legislators would create a 6% to 9% sales tax on any Virgin Galactic space tourist flights that take off from Spaceport America.

“If the flights really became regular, that could be a nice source of income, not only for the state but also from the GRT shared with the local communities,” [one of] the bill’s … sponsors, Democratic Rep. Matthew McQueen, said.

…”I can’t think of a particularly good reason why we wouldn’t tax this activity,” McQueen said.

McQueen might be too stupid to think of a reason, but I can think of dozens, and they are called the many other airport runways across the globe where Virgin Galactic can launch tourists and bypass this tax. The company already has agreements with several.

The stupidity of this legislative proposal at this time is compounded in that Virgin Galactic, the only customer Spaceport America presently has, is struggling badly. It has yet to fly any commercial flights, and is facing investor lawsuits and an aging fleet. Adding a tax on top of these problems could kill it, thus making this bill a perfect example of killing the goose that laid the golden egg, before the goose is even born. Moreover, it will certainly discourage anyone else from launching from New Mexico, especially as there are so many other spaceport options popping up worldwide with no such sales tax.

Startup building satellite electric thrusters signs deal with startup building refueling tankers

8:49 am

Capitalism in space: Phase Four, a startup building a new electric xenon thruster for use in satellites has signed an agreement with Orbit Fab, a startup building refueling systems for satellites already in orbit.

Under the agreement announced Jan. 24, the companies will work together to evaluate the refueling potential of traditional electric propulsion propellants like xenon for Phase Four Maxwell engines as well as new propellants like Advanced Spacecraft Energetic Non-Toxic propellant or ASCENT, a monopropellant developed by the Air Force Research Laboratory.

Orbit Fab last year launched its first prototype tanker, successfully testing the refueling port which it wants satellite makers to use so that future tankers can refuel them.

Webb successfully inserted in final orbital position at the Sun-Earth Lagrange point

3:01 pm

The James Webb Space Telescope today successfully completed a five minute firing of its engines to place it at the Sun-Earth Lagrange point dubbed L2.

Webb’s orbit will allow it a wide view of the cosmos at any given moment, as well as the opportunity for its telescope optics and scientific instruments to get cold enough to function and perform optimal science. Webb has used as little propellant as possible for course corrections while it travels out to the realm of L2, to leave as much remaining propellant as possible for Webb’s ordinary operations over its lifetime: station-keeping (small adjustments to keep Webb in its desired orbit) and momentum unloading (to counteract the effects of solar radiation pressure on the huge sunshield).

Engineers will spend the next three months aligning the segments of Webb’s large primary and secondary mirrors, while they wait for the telescope to cool down to the ambient very cold temperatures required for it to detect the tiny infrared heat emissions from very faint very very very distant objects.

U-shaped meandering Martian ridge

Broad U-Shaped meandering ridge on Mars
Click for full image.

Cool image time! The photo to the right, rotated, cropped, and reduced to post here, was taken on December 3, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what the scientists label a “Broad U-Shaped Ridge”. The two black squares are merely areas where no data was gathered.

Is this a fossilized river, of which scientists have identified more than 10,000 in the Arabia Terra transition region between the northern lowland plains and the southern cratered highlands? Arabia Terra however is literally on the other side of Mars, very far away.

The location, as shown in the overview map below, instead suggests that, if this U-shaped meander is a fossilized river, it isn’t one created by water or ice.

Another study says Mars does not have liquid water under its south pole

The uncertainty of science: A new study now claims that the presumed detection of lakes of liquid water under the Martian southern polar ice cap in 2018 was likely wrong, and that the detection was more likely volcanic rock.

The researchers think their conclusion — volcanic rock buried under ice — is a more plausible explanation for the 2018 discovery, which was already in question after scientists calculated the unlikely conditions needed to keep water in a liquid state at Mars’ cold, arid south pole.

“For water to be sustained this close to the surface, you need both a very salty environment and a strong, locally generated heat source, but that doesn’t match what we know of this region,” says the study’s lead author, Cyril Grima, a planetary scientist at The University of Texas at Austin Jackson School of Geosciences.

So my readers know how uncertain all of this is, note that the 2018 discovery of underwater liquid water was later confirmed by other scientists in 2020, then rejected by different researchers in 2021, who claimed it was clay instead.

In other words, the scientists have some inconclusive data that could mean many different things, either water, clay, volcanic rock, or maybe something else that someone hasn’t yet suggested. To really answer the question will require far more data, with some like required in situ on Mars itself.
