Rather than use American manned capsules, NASA is considering buying more Soyuz astronaut flights

10:32 am

Because of the delays imposed by its safety panel in the development of two American-made manned capsules, NASA is now considering buying more Soyuz astronaut flights from Russia.

Past experience has shown the difficulties associated with achieving first flights on time in the final year of development. Typically, problems will be discovered during these test flights. The consequences of no US crew on ISS warrant protection by acquiring additional seats. The absence of U.S. crewmembers at any point would diminish ISS operations to an inoperable state,” noted a procurement document published on February 13.

NASA is considering contracting with the State Space Corporation “Roscosmos” for these services on a sole source basis for two (2) Soyuz seats and associated services to the International Space Station (ISS) on the Russian Soyuz spacecraft vehicle. This transportation would be for one crewmember in the Fall of 2019 and one crewmember in the Spring of 2020.

Remind me again: What country does NASA work for? From this I think it is Russia, not the United States. The agency has no problem putting its astronauts on a Soyuz rocket, even though Russia has had chronic quality control problems that not only caused a Soyuz launch abort last year but also had someone drill a hole in a manned capsule, an act of sabotage that Russia has still not explained or solved.

Meanwhile, it slow-walks and delays in any manner it can the manned efforts of two American companies, so that it is forced to use Russian rockets. This is unconscionable. Where is Trump, the “America-First” guy? Why isn’t he stepping in and putting an end to this political gamesmanship that clearly favors a foreign power over American companies?

IAU approves China’s proposed names for Chang’e-4 landing site

10:07 am

That was fast! The International Astronomical Union (IAU) has approved all of the proposed names that China submitted for the features at or near Chang’e-4 landing site.

The IAU Working Group for Planetary System Nomenclature has approved the name Statio Tianhe for the landing site where the Chinese spacecraft Chang’e-4 touched down on 3 January this year, in the first-ever landing on the far side of the Moon. The name Tianhe originates from the ancient Chinese name for the Milky Way, which was the sky river that separated Niulang and Zhinyu in the folk tale “The Cowherd and the Weaver Girl”.

Four other names for features near the landing site have also been approved. In keeping with the theme of the above-mentioned folk tale, three small craters that form a triangle around the landing site have been named Zhinyu, Hegu, and Tianjin, which correspond to characters in the tale. They are also names of ancient Chinese constellations from the time of the Han dynasty. The fifth approved name is Mons Tai, assigned to the central peak of the crater Von Kármán, in which the landing occurred. Mons Tai is named for Mount Tai, a mountain in Shandong, China, and is about 46 km to the northwest of the Chang’e-4 landing site.

Compare this fast action with the IAU’s approval process for the names the New Horizons team picked for both Pluto and Ultima Thule. It took the IAU more than two years to approve the Pluto names, and almost three years to approve the Charon names. It is now almost two months after New Horizons’ fly-by of Ultima Thule, and the IAU has not yet approved the team’s picks for that body.

Yet it is able to get China’s picks approved in less than a month? Though it is obviously possible that there is a simple and innocent explanation for the differences here, I think this illustrates well the biases of the IAU. Its membership does not like the United States, and works to stymie our achievements if it can. This factor played a part in the Pluto/planet fiasco. It played a part in its decision to rename Hubble’s Law. And according to my sources, it was part of the background negotiations in the naming of some lunar craters last year to honor the Apollo 8 astronauts.

The bottom line remains: The IAU has continually tried to expand its naming authority, when all it was originally asked to do was to coordinate the naming of distant astronomical objects. Now it claims it has the right to approve the naming of every boulder and rock anywhere in the universe. At some point the actual explorers are going to have to tell this organization to go jump in a lake.

Major natural gas discovery off of South Africa coast

7:31 pm

The French oil and gas company Total has made a major natural gas discovery off the coast of South Africa that could contain one billion barrels.

Total said it had made a significant gas condensate discovery after drilling its Brulpadda prospects on Block 11B/12B in the Outeniqua Basin.

“It is gas condensate and light oil. Mainly gas. There are four other prospects on the license that we have to drill; it could be around 1 billion barrels of total resources of gas and condensate,” [Chief Executive Patrick] Pouyanne said.

Big money here, which can change the balance of power in terms of fossil fuel energy resources.

Hat tip Max Hunt. I had missed this when it was announced on February 7.

Monitoring a fresh-looking Martian landslide

Click for full image

Time for two cool images! To the right are two images taken by the high resolution camera on Mars Reconnaissance Orbiter (MRO), the top one taken in April 2012, and the bottom taken in December 2018. Both have been cropped and reduced slightly in resolution to post here.

The second image is trying to answer, in only a small way, one of the most fundamental questions of the Martian environment: How fast does it change? The images from orbit have periodically seen evidence of new impacts. MRO images have tracked dust devil tracks. And we know that somehow water, ice, wind and volcanic activity have eroded and reshaped the surface over eons.

What we don’t know truly and with detail is the pace of these changes, with any accuracy. The pace of some things over time seems obvious. For example, Mars’s inactive but gigantic volcanoes suggest that once volcanism was very active, but over time has ceased so that today it is unclear if any is occurring. Similarly, the geological evidence suggests that in the far past water flowed on the surface, producing catastrophic floods. Now that liquid water is all but gone, and this erosion process as ceased.

Hawai’i public radio joins campaign against spaceport

9:30 am

According to an article today by Hawaii’s local NPR station, it would be a bad idea to build a new spaceport there, based on the experience of Alaska residents near their own similar spaceport.

This article could be the poster child for fake news. It very biased, indicating that this local NPR station has decided to join the campaign to block construction of the spaceport on the state’s Big Island. For example, despite a title (“Alaska Residents Urge Caution to Hawaiʻi Officials Considering Spaceport”) that implies strong opposition in Alaska to their spaceport, there is no evidence in the article to support that implication. The article only inteviews two Alaska residents, both of whom admit to being strong opponents of their own spaceport, from the beginning. This is hardly a fair sampling of local opinion, and certainly does not give us a good picture of the impact the spaceport has had in Alaska.

This article’s bias is further compounded in that it only quotes one Hawaiian, a state senator who strongly opposes the proposed Hawaiian spaceport.

While there might be strong opposition to both the Alaskan and Hawaiian spaceports, this article is not very convincing. If anything, it makes me skeptical, and suspicious that the entire opposition is a ginned up political campaign, of which this NPR station is now willingly participating.

SpaceX protests NASA launch contract to ULA

8:59 am

Turf war! SpaceX has filed a protest against a NASA launch contract award to ULA for almost $150 million for the Lucy asteroid mission in 2023.

In a statement, SpaceX, the California company founded by Elon Musk, said it was the first time it had challenged a NASA contract.

“SpaceX offered a solution with extraordinarily high confidence of mission success at a price dramatically lower than the award amount,” the company said in a statement to The Washington Post. “So we believe the decision to pay vastly more to Boeing and Lockheed for the same mission was therefore not in the best interest of the agency or the American taxpayers.”

This protest might explain the politics of two other stories recently:

In the first case two California politicians are using their clout to pressure the Air Force for the benefit of SpaceX. In the second the Air Force inspector general office is using its clout to pressure the Air Force to hurt SpaceX.

All these stories illustrate the corrupt crony capitalism that now permeates any work our federal government does. In order to get government business, you have to wield political power, which means you need to kowtow to politicians and bureaucrats. Very ugly, and very poisonous.

Asteroid to eclipse Sirius, the sky’s brightest star, on February 18

8:46 am

On February 18, 2019 a four-mile wide asteroid is going to pass in front of Sirius, the sky’s brightest star, and block its light for just under two seconds.

Can a 7-kilometer-wide asteroid make Sirius disappear? You bet it can. That just might happen on Monday night, February 18th. That evening around 10:30 p.m. MST (5:30 UT February 19th), there’s a good probability that the 17th-magnitude 4388 Jürgenstock will occult the sky’s brightest star for up to 1.8 seconds. Visibility stretches along a narrow path from the southern tip of Baja California to the Las Cruces–El Paso region, up through the Great Plains, and north to the Winnipeg area. While only a limited number of people may see this event, anytime Sirius disappears, however briefly, it’s news!

In the U.S. the narrow path cuts through New Mexico, Colorado, Nebraska, South Dakota, and North Dakota. If you live in or near this path, this is definitely worth watching, especially since it will be happening at a convenient hour in the evening.

Update your GPS before April 6 or it might not work!

8:31 am

Older GPS and those that have not recently updated their firmware might not work properly after April 6, 2019.

GPS signals from satellites include a timestamp, needed in part to calculate one’s location, that stores the week number using ten binary bits. That means the week number can have 210 or 1,024 integer values, counting from zero to 1,023 in this case. Every 1,024 weeks, or roughly every 20 years, the counter rolls over from 1,023 to zero.

The first Saturday in April will mark the end of the 1,024th week, after which the counter will spill over from 1,023 to zero. The last time the week number overflowed like this was in 1999, nearly two decades on from the first epoch in January 1980.

You can see where this is going. If devices in use today are not designed or patched to handle this latest rollover, they will revert to an earlier year after that 1,024th week in April, causing attempts to calculate position to potentially fail. System and navigation data could even be corrupted, we’re warned.

Devices after 2010 should be all right, but it is advised to update the firmware to the latest version. Earlier devices might not fare so well.

The issue here is not so much handheld outdoor GPS units, but the GPS in smartphones as well as elsewhere. If you think a device you own uses GPS in any aspect, it is probably wise to update its firmware. The world is not going to end if you don’t, but you will guarantee that you will avoid some annoying inconvenience by doing so.

The anti-Semitic and bigoted Democratic Party

6:34 pm

Link here. I was going to write up something similar today, but Jeff Dunetz has done it for me.

His focus is partly that of the mainstream press’s effort to cover-up this bigotry, but in the process he also documents that bigotry quite well, documenting the support given to known anti-Semites and their causes by more than three dozen major Democratic elected officials, including Barack Obama, Congresswoman Maxine Waters (D-California), Senator Chuck Schumer (D-New York), Senator Kirsten Gillibrand (D-New York), Congressman Jerold Nadler (D-New York), Senator Kamala Harris (D-California), Senator Cory Booker (D-New Jersey), and Congressman James Clyburn (D-South Carolina), as well as newly elected Congress critters Rashida Tlaib (D-Michigan), Alexandria Ocasio-Cortez (D-New York), and this week’s star bigot, Ilhan Omar (D-Minnesota).

Nor have I listed every elected Democrat named. The bigotry that is taking over the Democratic Party is extensive. Nor is this a sudden event. It has been on-going now for decades, with no push back from the press or anyone within that party. It has now gotten so bad that the party routinely and willingly seeks the endorsements of known bigots like Al Sharpton and Louis Farrakhan.

Yet, in America it is still a safe bet that a large percentage of Jews will still be knee-jerk Democratic voters. It is this blind support that makes me so pessimistic for the future. The Democratic Party needed a house-cleaning by the voters more than twenty years ago, during the 1990s, and did not get it. Since then the corruption has grown to a point that it now is running the party. Yet the voters still support them.

Be warned. The worst is yet to come.

NASA officially declares Opportunity dead

1:44 pm

NASA today officially announced that the rover Opportunity — built to last 90 days — is dead, only three weeks after celebrating its fifteenth anniversary operating on the Martian surface.

This is what project scientist Steve Squyres had to say about the rover’s finish:

“When I saw that the storm had gone global, I thought this could be it,” said Squyres, explaining that Opportunity was a solar-powered vehicle and needed the sun for energy. “To have Opportunity – designed for 90 days – taken out after fourteen and a half years by one of the most ferocious dust storms to hit the planet in decades, you have got to feel pretty good about it.”

He said: “It was an honorable end, and it came a whole lot later than any of us expected.”

The article gives some nice background into the personal stories of many of the scientists who worked on Opportunity for all those years. For some overall scientific context, see this article. Or you can read the many rover updates I have written in the past two and a half years, which will give you a detailed sense of Opportunity’s travels along the rim of Endeavour Crater.
