NASA delays unmanned test of manned Dragon again

9:43 am

While not yet confirmed, industry rumors for the past twenty-four hours are saying that NASA has once again forced a delay in the launch of SpaceX’s unmanned test of manned Dragon, pushing it back into March.

I have linked to one article, but I have been hearing these rumors from a number of sources.

This delay, if true, will cause SpaceX scheduling problems in numerous ways. First, it will conflict with the second Falcon Heavy launch, presently planned for March using the same launchpad. Second, it forces a pushback on the manned Dragon launch. Because SpaceX will use this capsule to fly its launch abort mission, it needs at least three months to prep this capsule for its reuse. Assuming that is a success, it will then need three more months to assess that launch abort flight and prepare for the manned flight. This means the manned flight cannot happen prior to October.

Why the delays? Nowhere in this article or in any of the rumors I have heard has any real reason been given. The article says the following, with the important words highlighted:

As of the first week of December 2018, SpaceX was reportedly planning towards a mid-January 2019 launch debut for Crew Dragon. By the end of December, DM-1 was no earlier than the end of January. By the end of January, DM-1 had slipped to from late-February to NET March 2019. Put in slightly different terms, SpaceX’s Crew Dragon launch debut has been more or less indefinitely postponed for the last two months, with planning dates being pushed back at roughly the same pace as the passage of time (i.e. a day’s delay every day).

Admittedly, DM’s apparently indefinite postponement may well be – and probably is – more of an artifact than a sign of any monolithic cause. While the US government’s longest-ever shutdown (35 days) undoubtedly delayed a major proportion of mission-critical work having to do with extensive NASA reviews of SpaceX and Crew Dragon’s launch readiness (known as Readiness Reviews), much of the 60+ day DM-1 delay can probably be attributed to the complexity of the tasks at hand. Being as it is the first time SpaceX has ever attempted a launch directly related to human spaceflight, as well as the first time NASA has been back at the helm (more or less) of US astronaut launch endeavors in more than 7.5 years, significant delays should come as no surprise regardless of how disappointing they may be. [emphasis mine]

The first paragraph above outlines the endless delays that appear to me to be entirely caused by NASA’s endless review process, much of it designed solely to delay things, for political reasons. SpaceX has clearly been ready to launch since December. Moreover, NASA is somewhat irrelevant to this launch, as it is run by a SpaceX launch team on a SpaceX-run launchpad. The delays are all paperwork related, imposed by NASA bureaucrats hostile to this commercial private spacecraft because it is showing the world NASA’s own inability to build its own manned rocket and spacecraft, SLS/Orion.

These NASA bureaucrats are clearly putting their own interests ahead of the interests of the nation. While they play petty political games with this launch, their delays risk putting us in the position next year of having no way to ferry our own astronauts to and from our own space station. The contract with Russia runs out this year, and Russia has said that it would be very difficult for them to quickly schedule more flights beyond that.

Meanwhile, what is Trump doing? Nothing. He is allowing this, even though he has the power to prevent it.

Chinese cubesat snaps picture of Earth and Moon from deep space

9:21 am

The Moon and Earth

A interplanetary cubesat, Longjiang-2, launched with China’s communications relay satellite that they are using to communicate with Chang’e-4 and Yutu-2 on the far side of the Moon, has successfully taken a picture of both the Moon and Earth, as shown in the picture on the right.

Longjiang-2 is confirming what the MarCo cubesats proved from Mars, that cubesats can do interplanetary work.

And the picture is cool also. This was taken on February 3, when the entire face of the Moon’s far side is facing the Sun, illuminating it all. This timing also meant that the globe of the Earth would be entirely lit.

LRO photographs Chang’e-4 on lunar surface

9:00 am

Chang'e-4 on the lunar surface

The Lunar Reconnaissance Orbiter (LRO) science team has released a spectacular oblique image that shows Chang’e-4 on the floor of Von Kármán crater.

Four weeks later (30 January 2019), as LRO approached the crater from the east, it rolled 70° to the west to snap this spectacular view looking across the floor towards the west wall. Because LRO was 330 kilometers (205 miles) to the east of the landing site, the Chang’e 4 lander is only about two pixels across (bright spot between the two arrows), and the small rover is not detectable. The massive mountain range in the background is the west wall of Von Kármán crater, rising more than 3000 meters (9850 feet) above the floor.

The image on the right has been reduced to post here. If you click on it you can see a larger version, but you need to download a very large file at the above link to see it at full resolution.

Boeing partners with commercial supersonic jet startup

2:36 pm

Boeing today announced that it is partnering with startup Aerion Corp to build a 12-passenger commercial supersonic jet, dubbed the AS2.

Boeing said it would provide engineering, manufacturing and flight-test resources to bring the AS2 to market. The amount of the investment wasn’t disclosed.

The first flight for the plane — which, at about 1,000 miles per hour, will cruise 70 percent faster than today’s quickest business jets — is scheduled for 2023. Launch customer Flexjet, a fractional aircraft operator, has ordered 20 of the models. The 12-passenger aircraft has a list price of $120 million.

This isn’t the first or only private effort going on right now to develop supersonic jets for commercial travel. Another company, Boom Supersonic, has raised significant capital and already has its own orders for planes, though as far as I can tell it did not fly its initial test flights in 2018, as they had promised.

MarCO interplanetary cubesats likely dead

2:29 pm

More than two months after they provided relay communications for the landing of InSight on Mars, and more than a month since any contact has been heard from them, engineers now consider the two MarCO cubesats to likely be dead.

Now well past Mars, the daring twins seem to have reached their limit. It’s been over a month since engineers have heard from MarCO, which followed NASA’s InSight to the Red Planet. At this time, the mission team considers it unlikely they’ll be heard from again.

MarCO, short for Mars Cube One, was the first interplanetary mission to use a class of mini-spacecraft called CubeSats. The MarCOs – nicknamed EVE and WALL-E, after characters from a Pixar film – served as communications relays during InSight’s landing, beaming back data at each stage of its descent to the Martian surface in near-real time, along with InSight’s first image. WALL-E sent back stunning images of Mars as well, while EVE performed some simple radio science.

All of this was achieved with experimental technology that cost a fraction of what most space missions do: $18.5 million provided by NASA’s Jet Propulsion Laboratory in Pasadena, California, which built the CubeSats.

WALL-E was last heard from on Dec. 29; EVE, on Jan. 4. Based on trajectory calculations, WALL-E is currently more than 1 million miles (1.6 million kilometers) past Mars; EVE is farther, almost 2 million miles (3.2 million kilometers) past Mars.

Their loss of contact more than a month after the November landing of InSight actually shows their incredible success. Both MarCO cubesats functions well past Mars, demonstrating that these tiny satellites can do much of the same things bigger satellites costing billions do.

The location for a future Martian colony?

Pit draining into Kasei Valles

Regular readers of this webpage will know that I am a caver, and am fascinated with the pits and caves that have so far been identified on Mars, as illustrated by an essay I wrote only last week.

Some of the cave research I have cited has being led by planetary scientist Glen Cushing of the U.S. Geological Survey. Two weeks ago Dr. Cushing sent me a slew of pictures of caves/pits that he has accumulated over the years, many of which he has not yet been able to highlight in a paper. At least two were images that I had already featured on Behind the Black, here and here.

One pit image however I had never seen. A cropped and reduced close-up is shown on the right, with the full photograph viewable by clicking on the image. In many ways this pit is reminiscent of many pits on Mars. Its northern rim appears to be an overhang several hundred feet deep that might have an underground passage continuing to the north. The southern lip is inviting in that its slope appears to be very accessible for vehicles, meaning this pit/cave might be a good location to build a first colony.

Because of that accessible southern lip, I decided to do more digging about this particular pit. I was quickly able to find the uncaptioned release of the complete image by doing a quick search through the image catalog of Mars Reconnaissance Orbiter’s (MRO) high resolution camera. That image, reduced and cropped to post here, is shown below, on the right.

The story of an American family that moved to Russia

10:36 am

Link here. Russia has enormous problems, and I would be the last person to suggest leaving the United States to live there. Nonetheless, it is very instructive to read this article and the detailed explanation given by the father, Hal Freeman, as to why they moved.

The traditional values, the loss of which many in America are lamenting, are largely the values of the Russian culture in which I live. I do not write as someone who has been told this. I live here. The Russian Orthodox Church has a strong influence on local life. There are also active Catholic and Protestant churches in my town. The Church and State work together at a national level. For example, both want to reduce the numbers of abortions which skyrocketed during the Communist era because abortion was commonly used for birth control. The Church has made a strong commitment to help women in “crisis pregnancies.” The laws are more restrictive now about when and for what reason abortions can be performed. Watching the news here after Gov. Cuomo signed the bill in New York permitting late term abortions, I was struck by the contrast between the agony of my Christian friends’ posts on Facebook and the smiles and celebrations of the governor and legislators in New York. Abortions are still performed in Russia, but the numbers are steadily declining and no one smiles, laughs or brags about them.

I realize many in America are very glad that the American government is intervening and the understanding of “morality” has changed radically. They applaud freedoms won for gay, lesbian, trans-gender and many other Americans who have been oppressed. They have the right to rejoice: They won. The Benedict Option is one way for those on the other “side” to adapt. Many have been and are living it out. Others, like me, decided it was not in our family’s best interest to risk the future of our children to stay. After the New York decision on abortion I received an e-mail from an American Orthodox mother asking questions about moving to Russia. She realized the struggles involved in such a move. She wrote, however, “We have to move. No matter how well we are doing in home schooling and church, we cannot keep the government out of the lives of our children.”

If you wish to be an adult, it requires you to be brutally honest about life, pushing aside your emotions to rationally think about the world around you. This article places that demand upon ordinary but moral Americans, especially those living in leftist-controlled regions on the coasts and big urban cities. Are the political policies being pursued in those places going to make the future good or bad for your children? Freeman decided they would not, and for the sake of his kids he moved.

Not everyone can move, or should. Instead, I would advocate Americans look hard at these modern leftist policies and begin the fight to stop them, here and now. Our children’s future depends on it. If we do not, they will find themselves starving in a place not unlike today’s bankrupt socialist Venezuela.

Decline continues in 2018 in geosynchronous satellite industry

9:39 am

Capitalism in space: According to this article from Space News, 2018 saw a continuing decline in orders for the construction of new large geosynchronous communications satellites.

Last year’s poor harvest of five commercial orders for large geostationary communications satellites proved even worse than 2017’s surprise low of just seven orders. Manufacturers continue to vie for fewer such contracts as satellite operators hold off buying new spacecraft while they wait for breakthrough advances in high-throughput technology and assess the potential of small-satellite constellations. [emphasis mine]

The highlighted text provides the explanation. The decline isn’t because the use of space for communications is going away, but because the technology is shifting from a handful of large geosynchronous satellites to many tiny low orbit constellations. What this means for the launch industry is that the smallsat rocket companies (Rocket Lab, Virgin Orbit, Vector) are in the driver’s seat, while the big rocket companies (SpaceX, Arianespace, ULA, etc) might be left holding the bag. These big rockets won’t go away either, but will become much more dependent on government contracts, either for the military or for civilian manned space.

The article provides a very detailed overview of 2018 and is definitely worth a full read.

SpaceX test fires next generation rocket engine

9:16 am

Capitalism in space: This week Elon Musk tweeted pictures of the first static test firing of the first flight Raptor engine, to be used on SpaceX’s next generation rocket, the Super Heavy first stage and the Starship upper stage.

The billionaire entrepreneur also tweeted out several videos of the 3-second test, which took place at the company’s development facility in McGregor, Texas.

Starship is the 100-passenger stainless-steel vehicle SpaceX is building to take people and cargo to Mars and other distant destinations. Starship will launch atop a giant rocket SpaceX calls Super Heavy. Both of these vehicles will be reusable and Raptor-powered. Starship will sport seven of the new engines, and Super Heavy will use 31 Raptors to get off the ground.

A “hopper” prototype that SpaceX will use to test the Starship design on short flights within Earth’s atmosphere will have three Raptor engines. This hopper will debut soon, Musk has said — perhaps within the next month or so, if everything goes according to plan.

This engine appears to be the first built with the intention to actually fly, and is likely going to be used in that “hopper” prototype.
