Two Dragon Mars missions in 2020?

7:06 pm

It appears that SpaceX is considering flying two test Dragon capsules to Mars in 2020.

NASA’s manager of science missions, Jim Green, said on Tuesday that the 2020 launch window when Earth and Mars are in favorable alignment for relatively short transits is getting crowded. Speaking Tuesday at the Humans to Mars conference in Washington, DC, Green said, “Every 26 months, the highway to Mars opens up, and that highway is going to be packed. We start out at the top of that opportunity with a SpaceX launch of Red Dragon. That will be followed at the end of that opportunity with another Red Dragon. Those have been announced by SpaceX.” NASA plans to launch a Mars lander in 2020 as well.

Two Red Dragon missions in 2020 have not yet formally been announced by SpaceX. Company spokesman John Taylor told Ars he would have to look into the question of sending two Dragons to Mars in 2020. However, other industry sources told Ars this is definitely under consideration by SpaceX, although no final decisions have been made.

That would mean two Falcon Heavy launches that year, just for this. And it would happen long before NASA manages its first launch of a complete SLS rocket.

Aetna leaves last two Obamacare exchanges

3:50 pm

Finding out what’s in it: Aetna has pulled out of its last two Obamacare exchanges, in Delaware and Nebraska.

Aetna projected more than $200 million in losses from its exchange plan businesses this year following a loss of $700 million for 2014 through 2016. The insurer attributed the losses to “marketplace structural issues, that have led to co-op failures and carrier exits, and subsequent risk pool deterioration.” Aetna said it had 964,000 individual commercial plan members as of the end of 2016, but that number dropped to 255,000 at the end of March.

Essentially, Obamacare is destroying the health insurance industry, because no insurance company can afford to offer insurance when anyone can simply wait until they are sick — “a pre-existing condition” in the politically stupid parlance of the time — before buying insurance. This also means that the Republican plan, in whatever form it will be take when it finally reaches Trump’s desk, will do nothing to save the industry either, since it appears that the Republicans are terrified of being called mean and will thus keep the requirement that insurance companies sell insurance to anyone, whether they are sick or not.

New multi-wavelength image of Crab Nebula

12:00 pm

Crab Nebula

Cool image time! The image on the right, reduced and cropped to show here, was created in November 2012 using a number of different telescopes, both on the ground and in space, to image the Crab Nebula in as much of the entire electromagnetic spectrum as possible.

This image combines data from five different telescopes: The VLA (radio) in red; Spitzer Space Telescope (infrared) in yellow; Hubble Space Telescope (visible) in green; XMM-Newton (ultraviolet) in blue; and Chandra X-Ray Observatory (X-ray) in purple.

Be sure to check out the full image at the Hubble website. It is packed with fascinating details you need to zoom in to to see.

SLS oxygen tank dome dropped and damaged

11:46 am

You can’t make this stuff up. The dome for the oxygen tank for NASA’s SLS rocket has been accidently dropped and has been damaged beyond repair.

No details yet. It appears they can build another dome from available parts, but this will likely cause additional delays to the SLS launch schedule.

Update: More information here.

The damage was limited to the one dome section of the tank, which was not yet welded to the rest of the tank. “Assessments are ongoing to determine the extent of the damage,” she said. Henry said that the incident was classified as a “Type B” mishap. Such a mishap, according to NASA documents, covers incidents that cause between $500,000 and $2 million in damage. No one was injured, she said.

The liquid oxygen tank involved in the incident was a qualification model, intended for testing, and not flight hardware. Henry said it wasn’t immediately clear how long the investigation would take.

Palestinian Authority stops shipping medicine to Gaza

11:02 am

They’re such nice people! Because of the political battle between Hamas, running Gaza, and the Palestinian Authority, running the West Bank, the Palestinian Authority has stopped its quarterly shipments of medicine to Gaza.

Palestine Today quotes Dr. Munir Bursh, the pharmacy director at the Ministry of Health in Gaza, saying that the Palestinian Authority has stopped supplying medicines and baby formula to Gaza altogether. “90% of the treatment of cancer patients in the Gaza Strip has stopped due to the lack of the supply of drugs,” he said. Bursh added, “This is reprehensible and very strange, threatening a major health disaster up to the collapse of the health situation in Gaza, because the Ramallah government has been responsible for supplying medicine to Gaza, despite the deficit in the previous years.”

“Whoever made this decision is killing the entire people, and punishing the entire people.” He said that the PA supplies the Gaza Strip with medicines every two months, but it did not send any medicines for three months now.

Hospitals in Gaza are also worried about the closure of the Gaza power plant due to the spat between Hamas and Fatah, saying that they cannot desalinate the water needed for every day purposes.

The last line refers to the decision by the Palestinian Authority to stop paying its Gaza electrical bill, forcing Israel to stop supplying Gaza with electricity.

Japan begins testing new rocket engine

8:40 am

Capitalism in space: Japan has begun testing the rocket engine it will use in its next generation rocket.

The H-III will succeed the country’s current H-series rockets, H-IIA and H-IIB. The rocket will use commercially available components and a fuselage that can be mass produced, lowering launch costs to about half of the current price tag of approximately 10 billion yen ($88.6 million). The new, more powerful engine will allow the H-III to carry a midsize to large satellite weighing up to 6.5 tons — 60% more than the H-IIA.

If I understand this correctly, a launch with this new rocket will cost about $45 million, which will make it very competitive with SpaceX. At the same time, it is not as powerful, which means it will not serve the exact same customer base. Instead, its capacity makes it a direct competitor to India’s GSLV Mark III rocket.

SpaceX completes first static fire test of Falcon Heavy core stage

1:32 am

Capitalism in space: SpaceX this week successfully completed the first static fire engine test of the core stage of its Falcon Heavy rocket.

In a tweet, the company said that it completed the first static fire of the core stage of the rocket at the company’s McGregor, Texas, test site last week. The company did not disclose the precise date of the test or its duration. The company included in the tweet a video showing about 15 seconds of the test.

The Falcon Heavy uses three Falcon 9 first stages, or cores, along with an upper stage, an approach similar to United Launch Alliance’s Delta 4 Heavy. The two side booster cores for the first launch will be previously-flown Falcon 9 first stages, but the center core will be a new stage, modified to accommodate the side boosters.

The first launch is scheduled for sometime in the late summer, early fall.

The left moves to indoctrinate elementary school kids

9:18 am

Fascists: A new leftist movement has begun inserting racial and leftist indoctrination materials into elementary public school materials, teaching kids the evils of racism that are inherent in American society, before they are even aware that different races even exist.

Marxist theorist Paolo Freire advocated in Pedagogy of the Oppressed, that schools be used to inculcate radical values in students so they become agents of social change. Freire held that the so-called dominant pedagogy “silences” poor and minority children and that there is no such thing as a neutral educational system.

Joining Freire in his desire to use the educational system to level institutions is unrepentant communist terrorist and education theorist Bill Ayers, who has long advocated poisoning the minds of the young so they can agitate to fundamentally transform American society. “If we want change to come, we would do well not to look at the sites of power we have no access to; the White House, the Congress, the Pentagon,” he said in 2012. “We have absolute access to the community, the school, the neighborhood, the street, the classroom, the workplace, the shop, the farm.”

The article then describes at length actual examples of leftist and racist indoctrination in a variety of public elementary schools, going on right now. And make no mistake, the educational materials here are outright bigoted in their hatred of whites and American society. I am appalled that American parents are tolerating this.

The city of the future will watch you all the time

9:09 am

New computer software is making it possible for computers to quickly analyze the data provided by surveillance cameras, which in turn will allow businesses and government to track and identify city dwellers all the time.

Through partner businesses, Nvidia’s technology is set to take things even further, enabling autonomous aerial systems streaming video back from the sky, security robots driving themselves around looking for trouble spots, and ultra high resolution, super-wide panoramic cameras that capture a whole scene instead of needing to track and follow objects.

And instead of just recording and storing footage, every camera’s output would be constantly analyzed and crunched into useful data points. We’re talking facial recognition, vehicle recognition, and pattern tracking in road and pedestrian traffic.

Clearly this will be useful in a law enforcement and security sense, and several Nvidia partners are working along these lines. BriefCam, for example, is demonstrating technology that tracks individuals and vehicles through security footage, then produces super-quick review videos in which all events in a given time frame can be made to happen in a condensed format where a bunch of them are on screen at once.

It seems to me that this new technology fits very well with the urban leftist culture that runs most American cities these days. These fascist communities, run almost exclusively by Democrats, will cheer this surveillance as a way to protect themselves from bad things, including people with opinions they don’t like. Consider how useful this would have been to Berkeley, for instance, during its recent struggle to keep conservative speakers out of town.
