pit features on floor of crater

Time for some more weird Mars geology! Today the science team for the high resolution camera on Mars Reconnaissance Orbiter released its monthly batch of new images. There is a lot of interesting stuff buried therein, some of which I will feature periodically in the next month.

The image on the right, reduced in resolution to post here, is a good example. (If you click on the image you can see the full resolution version.) It shows a scattering of pits in three specific areas on the crater floor, all in a line going from the northeast to the southwest. Yet, the rest of the crater floor lacks similar pits, and is either very smooth or has a mottled appearance. Both the smooth and the mottled areas appear to have a very faint trend going from the northwest to the southeast, which to my eye appears caused by the general wind direction that flows across the crater floor.

Even more intriguing, the pits in these three areas appear to be mostly oblong and also trend from the northeast to the southwest, cutting across the general trend of the rest of the crater floor. You can see this in the cropped closeups from the full resolution image below, showing the two boxed areas indicated on the image on the right.

UN agreement reached on space sustainability

8:59 am

In February a UN committee helped negotiate a agreement with 87 nations for establishing rules for space sustainability.

The agreement was reached during a meeting of the United Nations Committee on the Peaceful Uses of Outer Space (COPUOS). COPUOS was created in 1959 as the main UN body to govern the exploration and use of space, and was instrumental in the creation of the five major space treaties. It has been the main multilateral forum where countries meet to discuss space issues and share updates on national activities and practices. As of 2018, those eighty-seven countries are formal members of COPUOS, with Bahrain, Denmark and Norway being the most recent additions. There are also nearly 40 observer organizations, including the Secure World Foundation.

…In 2016, the first set of 12 guidelines were agreed to by a consensus of all the members of COPUOS, and the mandate of the LTS Working Group was extended through 2018. The most recent meeting of STSC in February 2018 saw the LTS Working Group reach consensus on nine more guidelines and the preamble text, bringing the total to 21, as well as agreeing to review their implementation and potentially update them. The 21 guidelines represent countries’ best practices across a broad spectrum of space issues.

Though all of the guidelines essentially confirm policies that these nations have been following, they were reaffirmed by this agreement partly because of the Chinese anti-satellite test in 2007 that produced a lot of space junk.

A review of the guidelines reveals them to be mostly sensible and necessary. The problem is that this process is establishing the precedent that such rule-making should apply to all space activities, and it shall be imposed by UN committees of government bureaucrats here on Earth. For example, the process here appears to be entirely political, and involved none of the actual companies that build and produce rockets and satellites.

At some point in the future, such rule-making should be the responsibility of those who work and and live in space. I predict when that time comes, the UN and the political bureaucracies from these nations will be loath to give up this power. Stay tuned for the eventual rebellion that will follow.

Astronomers find a dozen black holes near center of Milky Way

8:40 am

Astronomers have discovered a dozen smaller black holes orbiting near Sagittarius A* (pronounced “A-star”), the supermassive black hole at the center of the Milky Way.

Charles Hailey from Columbia University in New York and colleagues used archival data from Nasa’s Chandra X-ray telescope to come to their conclusions. They report the discovery of a dozen inactive and low-mass “binary systems”, in which a star orbits an unseen companion – the black hole.

The supermassive black hole at the centre of the Milky Way, known as Sagittarius A* (Sgr A*), is surrounded by a halo of gas and dust that provides the perfect breeding ground for the birth of massive stars. These stars live, die and could turn into black holes there. In addition, black holes from outside the halo are believed to fall under the influence of Sgr A* as they lose their energy, causing them to be pulled into its vicinity, where they are held captive by its force. Some of these bind – or “mate” – to passing stars, forming binary systems.

They have extrapolated their data to predict the existence of thousands more of these small black holes near the galaxy’s center.

Sightseeing

8:48 am

Biosphere-2

Posting has been light the past few days, and will be today, because we have a friend visiting from back east. This of course provides an excuse to do some sightseeing. Yesterday we visited Biosphere-2, the first time I have ever been there, as shown in the picture above. Today we are heading down to Bisbee, Arizona.

I plan to write up my impressions of Biosphere-2 tomorrow. Stay tuned!

NASA’s horrible management of SLS

8:25 am

In this article from NASASpaceflight.com describing a recent status update from NASA of its SLS/Orion program (which remains years behind schedule and might see further delays) was the following quote, revealing much about NASA’s incompetence and corruption in building this boondoggle:

In contrast to the more centralized organization structure for the cancelled Constellation program, [SLS’s] three major programs [ground systems, Orion, and SLS] are managed independently: Exploration Ground Systems (EGS) based at KSC, Orion based at the Johnson Space Center (JSC) in Houston, Texas, and SLS based at the Marshall Space Flight Center (MSFC) in Huntsville, Alabama.

Each of the programs has resources to integrate with its other two partners, but ESD [Exploration Systems Development at NASA headquarters in DC] provides the overall coordination between all three. During Constellation, the equivalent organizations were projects directly managed by that now-cancelled program. [emphasis mine]

In other words, when Obama unilaterally cancelled Constellation (something he really didn’t have the power to do) and Congress micromanaged its reinstatement (creating SLS/Orion), the Obama administration and NASA abandoned a sensible management structure and allowed SLS/Orion to be a three-headed monster, difficult to coordinate and certain to go over-budget and fall behind schedule.

With this operational structure, even if SLS eventually flies successfully, it will be impossible for it to operate efficiently. Expect every one of its future efforts to always go over budget and to fall behind schedule.

Rocket Lab next launch window opens April 20

8:08 am

Capitalism in space: Rocket Lab today announced that the first official operational launch of its Electron rocket will take place in a window beginning April 20.

If this launch is successful, expect the company to begin to ramp up its launch pace. Their goal is to have the ability to launch once every three days, which will also give them the ability to quickly schedule payloads at a moment’s notice.

NOAA admits it wants the power to license all camera use in space

7:58 am

Government power grab: At a conference today a NOAA official revealed that its lawyers have decided to liberally interpret federal law so that the agency has the power to license all camera use in space.

According to Tahara Dawkins, director of Commercial Remote Sensing Regulatory Affairs (CRSRA) office,

[p]art of the licensing review for commercial remote sensing systems involves a check of any national security implications of that system, but it’s not clear what issues an onboard camera system, whose views of the Earth are typically low resolution and often obscured by the rocket itself, might pose.

Dawkins said that no previous SpaceX launches had NOAA commercial remote sensing licenses, even though many have flown onboard cameras, including several previous Iridium missions. An April 2 launch of a Falcon 9 from Florida carrying a Dragon cargo spacecraft had no such restrictions, she said, because that was considered a government mission. While the spacecraft is performing a mission under contract to NASA, the launch itself was considered commercial and licensed by the Federal Aviation Administration’s Office of Commercial Space Transportation.

NOAA was not aware of the previous launches that featured onboard cameras. “Our office is extremely small, and there’s a lot of things out there that we miss,” she said. “The onus is on the companies to come to us and get a license when needed.” [emphasis mine]

The highlighted words prove that the big publicity of the Falcon Heavy launch, showing the Tesla with the Earth in the background, instigated this stupidity. This office doesn’t have the slightest idea what is going on. Footage from rocket launches have become routine now for almost a decade. They saw the Tesla images and decided to exert their power, despite the fact that, as the article notes,

Part of the licensing review for commercial remote sensing systems involves a check of any national security implications of that system, but it’s not clear what issues an onboard camera system, whose views of the Earth are typically low resolution and often obscured by the rocket itself, might pose.

This is government overreach at its worst. If Trump is serious about cutting back regulation, he should step it now to shut this down.

SpaceX launches Dragon to ISS

8:03 am

SpaceX successfully launched a reused Dragon capsule into orbit yesterday, once again using a reused first stage.

To show you how routine this has become, I myself completely forgot the launch was happening yesterday, and spent that time doing my monthly bills. Oy.

They did not attempt to recover the first stage, using it instead to do re-entry flight tests as it landed in the Atlantic Ocean. I suspect they have decided that it is not cost effective to recover used first stages, and would rather dump them in the ocean than pay the cost to recover, test, and store them.

The leaders in the 2018 launch standings:

10 China
7 SpaceX
4 Russia
3 Japan
3 ULA

China and the U.S. continue to be tied in the national standings.

Near the Martian shoreline

1:20 pm

One of the prime areas of research for Mars planetary geologists is the region on Mars where the geography appears to transition from the southern cratered, rough terrain to the northern low, generally smooth, and flat plains. It is theorized by some scientists that the northern plains were once an ocean, probably shallow and probably intermittent, but wet nonetheless for considerable periods. The global map of Mars below, created by the laser altimeter on Mars Global Surveyor, clearly shows the obvious elevation differences between the low northern plans (blue) and the high, more cratered southern regions (changing from yellow to orange as you move higher).

Labeled global Map of Mars

Scientists have spent a considerable effort studying this transition zone (green on the map), illustrated by just one example I recently highlighted, showing that, though there does not appear to be a clear shoreline in many places, there is strong evidence that a shallow ocean repeatedly rose and fell in this transition zone, leaving behind geological ripple marks vaguely reminiscent of those seen on a beach caused by the rise and fall of the tides.

Today we highlight another example, taken in January 2018 at the location indicated by the cross on the above map.

Google and Amazon patent 1984-style devices that spy on you in your home

9:06 am

Another reason to dump these companies: Google and Amazon have both patented devices that are designed to spy on you at all times in your home.

The description of Google’s devices is particularly vile, and almost matches precisely the spying devices George Orwell created in 1984 that allowed the government to monitor its citizens 24 hours a day.

Google’s patent application outlines how audio and visual signals could be used to better understand a speaker’s mood or medical condition, according to the New York Times. The devices could listen to the ‘volume of the user’s voice, detected breathing rate, crying’. They could also detect a user’s coughing and sneezing.

The same patent applications reveals a device that could ‘recognize a T-shirt on a floor of the user’s closet’ with Will Smith’s face. It could then combine this with a browser history that shows searches for Mr Smith. This would allow Google to ‘provide a movie recommendation that displays, ‘You seem to like Will Smith. His new movie is playing in a theatre near you.’

In a separate patent application, Google describes a device that would give advice to parents for ‘areas of improvement’ such as spending more time with their children at supper. When children are near a drinks cabinet or are in their parents’ bedroom alone, the system may infer that mischief is likely to be occurring’, the patent read. On detecting mischievous behaviour, the smart device could even hand out punishments such as restricting mobile phone use.

Both Google and Amazon have made it clear in the past year that they are are increasingly partisan, strongly leftist with agendas favoring the Democratic Party. You therefore have to be a simpleton to think that this information will never be used by them for political reasons someday.

44 Democrats waived background checks for Imran Awan

8:53 am

Every Democrat in the House who hired Pakistani Imran Awan to run their computers, 44 in total, also exempted him from the required background checks.

All of them appear to have waived background checks on Imran Awan and his family members, even though the family of server administrators could collectively read all the emails and files of 1 in 5 House Democrats, and despite background checks being recommended for such positions, according to an inspector general’s report. The House security policy requires offices to fill out a form attesting that they’ve initiated background checks, but it also includes a loophole allowing them to simply say that another member vouched for them.

Among the red flags in Abid’s background were a $1.1 million bankruptcy; six lawsuits against him or a company he owned; and at least three misdemeanor convictions including for DUI and driving on a suspended license, according to Virginia court records. Public court records show that Imran and Abid operated a car dealership referred to as CIA that took $100,000 from an Iraqi government official who is a fugitive from U.S. authorities. Numerous members of the family were tied to cryptic LLCs such as New Dawn 2001, operated out of Imran’s residence, Virginia corporation records show. Imran was the subject of repeated calls to police by multiple women and had multiple misdemeanor convictions for driving offenses, according to court records.

This story is particularly disturbing. Either all 44 Democrats were incredibly stupid, or they actually wanted Awan capable of passing classified information to his sources in Pakistan. Either way, everyone of these Democrats is culpable, and if the latter is true, they are also traitors.

Tiangong-1 reentry window narrowed to only 3.4 hours and two orbits

5:30 pm

The sky is falling! The Tiangong-1 reentry window has now been narrowed to only 3.4 hours and two orbits, centered on 8:30 pm (Eastern) on April 1.

It appears the world might be dodging this very minor bullet. The new window, which the spacecraft has just now entered as I write this, has allowed for the first prediction on where it should come down, and it appears that this will be in the southern hemisphere in the Pacific west of South America.

Update: Tiangong-1 came down in the Pacific Ocean at 8:15 pm (Eastern) on April 1.

SpaceX ship returns with this week’s fairing apparently intact

8:08 am

Despite tweets from Elon Musk suggesting it had hit the water at “high speed,” SpaceX’s recovery ship appears to have returned with one half of the fairing intact.

There are several images at the link showing the fairing on the ship. That it recovered it out of the water without damage seems surprising and unlikely. Nonetheless, that it looks intact means that the parafoil managed to slow it down enough to limit damage as it hit the water, and the company seems to be making real progress towards making these fairings reusable.
