NASA picks Mars 2020 landing site: Jezero Crater

11:00 am

Jezero Crater

NASA has picked Jezero Crater has the landing site for its as yet unnamed 2020 Mars rover.

Jezero Crater is located on the western edge of Isidis Planitia, a giant impact basin just north of the Martian equator. Western Isidis presents some of the oldest and most scientifically interesting landscapes Mars has to offer. Mission scientists believe the 28-mile-wide (45-kilometer) crater, once home to an ancient river delta, could have collected and preserved ancient organic molecules and other potential signs of microbial life from the water and sediments that flowed into the crater billions of years ago.

Jezero Crater’s ancient lake-delta system offers many promising sampling targets of at least five different kinds of rock, including clays and carbonates that have high potential to preserve signatures of past life. In addition, the material carried into the delta from a large watershed may contain a wide variety of minerals from inside and outside the crater.

The geologic diversity that makes Jezero so appealing to Mars 2020 scientists also makes it a challenge for the team’s entry, descent and landing (EDL) engineers. Along with the massive nearby river delta and small crater impacts, the site contains numerous boulders and rocks to the east, cliffs to the west, and depressions filled with aeolian bedforms (wind-derived ripples in sand that could trap a rover) in several locations.

The red dot on the map of Mars below shows this location. The blue dot is Gale Crater where Curiosity landed. The purple dot is the landing site for the European ExoMars rover. The yellow dot is where Opportunity has been roving, and the black dot is Spirit’s location.

Computer model suggests universe has innumerable exomoons

10:28 am

A supercomputer simulation has shown that ice-giant planets like Uranus and Neptune can have their own dust disk during formation, thus allowing these kinds of planets to also form moons.

“So far it was believed that Uranus and Neptune are too light to form such a disk,” says the astrophysicist. Therefore, it was considered that the moons of Uranus could have formed after a cosmic collision – like our own moon, also a relatively infrequent event as the capture. Now the researchers who are also members of the NCCR PlanetS were able to refute this previous idea. Their extremely complex computer simulations reveal that in fact Uranus and Neptune were making their own gas-dust disk while they were still forming. The calculations generated icy moons in-situ, that are very similar in composition with the current Uranian satellites. From the simulations performed by the supercomputer called “Mönch” at CSCS it is clear that Neptune originally also was orbited by a Uranus-like, multiple moon system, but this must have been wiped out during the capture of Triton.

The new study has a much wider impact on moons in general, than only on our Solar System formation history. “If ice giants can also form their own satellites, that means that the population of moons in the Universe is much more abundant than previously thought,” summarizes Dr.Szulágyi.Ice giants and mini-Neptune planets are often discovered by exoplanet surveys, so this planet mass category is very frequent. “We can therefore expect many more exomoon discoveries in the next decade,” the astrophysicist says.

I actually don’t believe the assumption posited here that scientists previously believed Uranus and Neptune were too light to form disks. I think many astronomers might have believed that, while many others remained unsure, since it is more intuitive to expect such disks to form as these gas giants formed.

Either way, this computer model lends weight to those who believe the universe is littered with planets and moons, everywhere, many of which will exist in the habitable zones of all kinds of stars. These planets and moons might not have life, but they will be places we could live, when we begin colonizing interstellar space.

Hidebound government slowing smallsat industry

10:16 am

The smallsat industry has found itself slowed by the federal government’s reluctance to adopt the new technologies that allow tiny satellites to do the same things that once required big satellites.

Small satellites have been hailed as a game changer in the space industry, but the government’s slower than anticipated adoption of smallsat technology has been a disappointment for many companies. “When the smallsat movement started, the thinking was, ’We don’t need the government,’” said Bhavya Lal, a researcher at the IDA Science and Technology Policy Institute, a federally funded think tank. “But over the last five years, almost all the smallsat companies we talked to are eager for government contracts” to make up for lackluster commercial demand, she said. “It’s something they didn’t anticipate.”

IDA last year published a wide-ranging study of the small satellite industry. There is a “growing realization that there aren’t as many business customers as originally hoped,” Lal said. “Maybe that will change as broadband mega constellations come on line.” Companies like SpaceX and OneWeb are projected to build huge constellations of small satellites but projects have taken longer to materialize than predicted.

Advocates of small satellites say government agencies have little economic incentive to experiment with unfamiliar technology. They can afford to buy large satellites and have yet to be convinced that lower cost smallsats can provide comparable services. [emphasis mine]

I think the conclusion highlighted in the quote above is faulty, based on past data and not likely future events. They are looking at the customers that exist before the new smallsat rockets come on line. Once cheap access for smallsats is assured, from multiple launchers, I expect the number of business customers will rise quickly.

Nonetheless, there is no harm in lobbying our government for more business, as long as this new industry doesn’t become dependent on it. If that happens, expect costs to rise and innovation to slow.

Sunset/sunrise on Mars

10:07 am

The sun on Mars's horizon

Cool image time! The image on the right, reduced to post here, was taken by Curiosity during a photo campaign this week to monitor Mars’s atmosphere. It looks out to the horizon at the Sun. I think the view is eastward, at Mount Sharp, as the Sun rises, but I am not sure. It might be looking west across the crater rim at sunset.

If you click on the image you can see it at full resolution. The haziness in the atmosphere might be left over from this summer’s global dust storm, but probably not, as I have read numerous reports in connection with Opportunity saying the storm is completely over and the atmosphere has now cleared. More likely it is from the windy conditions that are simply present these days at Gale Crater.

Regardless, it is quite cool because it illustrates how far we have come since the first planetary missions half a century ago. We can now routinely watch a sunset on Mars.

Conscious Choice cover

Now available in hardback and paperback as well as ebook!

 

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

 
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.

 

“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of the Mars Society.

 

All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount. All editions can also be purchased direct from the ebook publisher, ebookit, in which case you don't support the big tech companies and the author gets a bigger cut much sooner.

 

Autographed printed copies are also available at discount directly from the author (hardback $29.95; paperback $14.95; Shipping cost for either: $6.00). Just send an email to zimmerman @ nasw dot org.

SpaceX delays today’s Falcon 9 launch using booster for 3rd time

9:53 am

Capitalism in space: SpaceX has delayed today’s Falcon 9 launch that would have been the first time a first stage had launched for the third time.

“Standing down from Monday’s launch attempt of Spaceflight SSO-A: SmallSat Express to conduct additional pre-flight inspections. Once complete, we will confirm a new launch date,” SpaceX representatives said via Twitter on Saturday (Nov. 17).

They did not offer further details, so it’s unclear what issue prompted the call for further inspection.

The delay is expected to be about a week. I suspect that they decided, after their standard prelaunch static fire last week, to review the data more carefully. The Block 5 first stage has already flown twice this year, in May and August. A launch in November means they are averaging a relaunch every three months, a pace that is far faster than NASA ever achieved in reusing its space shuttle.

SpaceIL gets $5 million for its lunar lander/rover

9:46 am

Capitalism in space: SpaceIL, the Israeli non-profit building a lunar lander/rover that had been a finalist in the Google Lunar X-Price, announced today that it has received a $5 million donation from a Canadian billionaire.

SpaceIL announced Monday that [Sylvan] Adams would be joining their groundbreaking project and donating $5 million to the effort. The nonprofit organization’s spacecraft is due to be launched in early 2019 and reach the moon two months later, making Israel only the fourth country to soft-land on the lunar surface.

“This contribution to strengthening the Israeli space program, and encouraging education for excellence and innovation among the younger generation in Israel, is the best gift I could have asked for,” said Adams, who recently celebrated his 60th birthday, as he announced his contribution at the Israel Aerospaces Industries (IAI) MBT Space Division in Yehud, where the spacecraft is being assembled.

SpaceIL has said it’s mission is focused on education and inspiring Israel’s youth. If so, it seems to me that it is missing the boat. There is money to be made marketing their ability to build inexpensive planetary spacecraft.

Looking at the south pole of the Milky Way

9:36 am

Link here. The link provides instructions for finding the spot in the sky that corresponds to the south pole of the galaxy, pointing in a perpendicular direction away from its center.

No star marks the position. It sits in the faint southern constellation of Sculptor, the sculptor’s studio, hence its identification is intellectual rather than sensorial.

This is the case of the dog that did not bark. The reason there is little to see there is that you will be looking down out of the plane of the galaxy, in a direction with the fewest stars to see. The view is therefore looking out of our galaxy, at intergalactic space, vast and empty.

Virgin Orbit completes first capture-carry flight of LauncherOne

9:29 am

Capitalism in space: Virgin Orbit yesterday completed the first capture-carry flight of LaunchOne, flying the rocket attached to the bottom of Cosmic Girl, its 747 launch vehicle.

The flight lasted 80 minutes in total, during which Virgin Orbit’s flight crew assessed the take-off, landing, and low-speed handling and performance of the integrated system.

“The vehicles flew like a dream today,” said Virgin Orbit Chief Pilot Kelly Latimer (Lt. Col, US Air Force, Ret.). “Everyone on the flight crew and all of our colleagues on the ground were extremely happy with the data we saw from the instruments on-board the aircraft, in the pylon, and on the rocket itself. From my perspective in the cockpit, the vehicles handled incredibly well, and perfectly matched what we’ve trained for in the simulators.”

They are aiming to begin commercial flights next year, and appear on schedule. If so, they will jump ahead into the number two spot in the smallsat rocket race, behind Rocket Lab but ahead of Vector.

China launches two GPS-type satellites

9:25 am

China yesterday used its Long March 3B rocket to successfully launch two more GPS-type satellites for its planned Beidou constellation of 35 satellites.

They have launched about half the constellation this year, and plan to complete it next year.

The leaders in the 2018 launch race:

32 China
18 SpaceX
11 Russia
8 ULA
8 Europe (Arianespace)

China has widened its lead over the U.S. to 32 to 30 in the national rankings. China also seems on schedule to meet or at least come very close to its predicted 40 launches this year, a number that doubles its previous high.

3D printed screws from fake moon dust

10:11 am

Researchers in Europe have successfully printed screws and gears using simulated moon dust.

These printed materials weren’t carbon-based plastic or metal, according to a statement from the ESA, but rather a sort of lunar ceramic. “Ground and sieved down to particle size, the regolith grains are mixed with a light-reacting binding agent, laid down layer-by-layer, then hardened by exposing them to light,” according to the statement. “The resulting printed part is then sintered in an oven to bake it solid.”

In other words, all these little gadgets had production histories closer to the dinner plate in your cupboard than the screws holding that cupboard together.

This is still an experimental project, so there’s a lot more testing to be done — including whether these parts are strong enough to stand up to the stresses of real-world use.

They might find these parts aren’t hard enough for their use as screws and gears, but finding a way to produce these parts in space rather than having them shipped from Earth will be essential for making any future space colony viable.

Luxembourg accepts full loss from Planetary Resources investment

10:05 am

Capitalism in space: Luxembourg this week admitted that its 12 million euro investment in Planetary Resources is a complete loss.

They had sold off their ten percent investment when a blockchain company purchased Planetary Resources on November 1. This article merely confirms the full loss from the companies sale.

When Planetary Resources was first revealed, the mainstream press went nuts touting its claims that it was an asteroid mining company, mostly because of the supposed involvement of several rich Google investors. I however had reservations, mainly because the company was selling itself as an asteroid mining company when there was no chance it was going to do any mining, for at least a decade.

Simply put, I do not like it when companies or governments make false and unrealistic claims. It raises a red flag in the back of my mind, which in turn makes me suspect that the company or government is almost certainly not going to achieve what it claims. Over the past decades I have learned to take that red flag seriously, and this is another case where it served me well.

SpaceX will not use Falcon 9 for BFR tests

9:49 am

In a series of tweets, Elon Musk revealed yesterday that SpaceX has decided it will no longer use its Falcon 9 to test Big Falcon Rocket (BFR) designs and has instead redesigned the BFR’s upper stage, dubbed the Big Falcon Spaceship (BFS), and will do those tests with that.

I suspect that the company got pushback from NASA and the Air Force about making any big changes to the Falcon 9 upper stage, and decided it was better to leave well enough alone. They have more flexibility making these changes and tests with BFS.

However, the main conclusion that I draw from writing up this post is that SpaceX has got to come up with better names for BFR and BFS. What they have now is boring and unwieldy. I am sure that Musk can think of two more exciting and easier to use names for the new rocket’s reusable first and second stages. And he should do it, now!

NASA suggests retirement of SLS when BFR and New Glenn fly

9:34 am

Capitalism in space: During an interview at a November 1st conference, a NASA official mentioned that if SpaceX’s Big Falcon Rocket (BFR) and Blue Origin’s New Glenn begin flying successfully the agency will seriously consider retiring SLS.

“I think our view is that if those commercial capabilities come online, we will eventually retire the government system, and just move to a buying launch capacity on those [rockets],” Stephen Jurczyk, NASA’s associate administrator, told Business Insider at The Economist Space Summit on November 1.

However, NASA may soon find itself in a strange position, since the two private launch systems may beat SLS back to the moon – and one might be the first to send people to Mars.

I have been saying that this should happen since almost the first day this website was started in 2011. To quote from a September 14, 2011 post:

To be really blunt, this new rocket, like all its predecessors, will never fly either. It costs too much, will take too long to build, and will certainly be canceled by a future administration before it is finished. It is therefore a complete waste of money, and any Congress that approves it will demonstrate how utterly insincere they are about controlling spending.

It appears that I was wrong with this prediction on one count. SLS might actually fly a few times, but only to allow its supporters in Congress and NASA to justify that support. When the private rockets come on line in the early 2020s, cheaper, faster, and better designed (with re-usability), NASA and Congress will then finally say that these rockets are better and that SLS will die, and they will also both make believe they were saying that from the very beginning.

Antares rocket launches Cygnus freighter to ISS

10:46 pm

Capitalism in space: Northrop Grumman’s Antares rocket today successfully launched its Cygnus freighter to ISS.

This was only the second launch this year by the division of Northrop Grumman that used to be Orbital ATK. They have been trying to launch a research satellite using their Pegasus rocket, but have had engineering issues that keep delaying it.

The leaders in the 2018 launch race remain unchanged:

31 China
18 SpaceX
11 Russia
8 ULA
8 Europe (Arianespace)

China continues to lead the U.S. in the national rankings, 31 to 30. The U.S. total now exceeds last year, and is the most this century. We have now had 91 launches this year, the most since 2014. I expect that number to go up significantly, with a real chance it will pass 100 launches for the first time since 1990, just prior to the fall of the Soviet Union.

Man attacked in Tucson for wearing MAGA hat

10:52 am

They’re coming for you next: A man was attacked and suffered a broken ankle in Tucson last week because he was wearing a pro-Trump MAGA hat.

Sparks says he was downtown last week wearing the iconic red hat and encouraging his fellow Tucsonans to vote Republican, when he was suddenly attacked from behind. “I felt a very strong grasp on my hat, and it pulled me back and grabbed a lot of hair,” Sparks told the outlet (video below). “The assailant had jumped onto my ankle from behind. And so I — not knowing yet my ankle was broken into four pieces — I turned around to grab and take the hat back. My hands latched onto the hat.”

At that point, he said, they both fell to the ground, his ankle shattered. “Then I heard the words Hitler, Nazi and Trump,” said Sparks. “He was shouting things like that.”

This is obviously Trump’s fault. And Maxine Waters should be proud at the willingness of this Democrat to follow her advice!

The fractured floor of Komarov Crater

10:35 am

Fractured floor of Komarov Crater

Cool image time! The Lunar Reconnaissance Orbiter (LRO) oblique image on the right, reduced significantly from the original to post here, shows the deeply fractured floor of Komarov Crater on the Moon’s far side. As noted at the image link,

The spectacular fractures that cut across the floor of Komarov crater [about 85 kilometers or 50 miles diameter] were formed when magma rose from the mantle, uplifting and fracturing the crater in the process. In this case the magma did not erupt to the surface, thus the fractures remain visible.

The Komarov fractures are quite large, the major left-to-right fracture that cuts across the center of the scene is over 500 meters deep [1,600 feet] and 2500 meters wide [1.5 miles]. When did they form? The large number of craters superimposed on the floor and fractures testifies to their ancient ages. Likely they are of the same vintage (>2.6 billion years) as the Mare Moscoviense lava plains just to the north

An overview of Komarov Crater as well as other LRO images of it can be found here.

The question that comes to my mind is the relative rarity of craters with such large fractures on their floors. I have noted this for Mars as well. It is expected that there is melt on the floor of all large impact craters. Why do a few produce such pronounced fractures, while most do not? This website posits one explanation, but its complexity leaves me unsatisfied. It also doesn’t explain why it happens only rarely.

Advisory panel to Space Council pans Gateway

9:54 am

The advisory panel to the Space Council gave NASA’s Gateway lunar orbiting platform low marks in a meeting in Washington yesterday.

NASA’s plan for returning to the Moon met with opposition today at a meeting of the National Space Council’s Users’ Advisory Group (UAG). Not only members of the UAG, but former NASA Administrator Mike Griffin, who was there as a guest speaker on other topics, offered his personal view that NASA is moving too slowly and the lunar orbiting Gateway is unnecessary.

Makes sense to me, especially based on the description of Gateway put forth by NASA at the meeting:

In the first part of the 2020s, NASA plans to launch series of very small and later mid-sized robotic landers and rovers, while at the same time building a small space station, currently called the Gateway, in lunar orbit. The Gateway is much smaller than the International Space Station (ISS) and would not be permanently occupied. Crews would be aboard only three months a year and eventually the Gateway would be a transit point for humans travelling between Earth and the lunar surface or Mars.

The presentation also said under this plan that Americans would not land on the Moon until 2028.

It is all fantasy. I guarantee if the government goes with Gateway it will not land on the Moon before 2035, and that is optimistic. Tied as it is to very expensive SLS and the government way of building anything, Gateway will likely see at least five years of delays, at a minimum. Remember also that the first manned launch of SLS is not expected now before 2024, and will likely have a launch cadence of less than one launch per year. How NASA expects to complete Gateway and then land on the Moon only four years later, using this rocket, seems very unrealistic to me.

This does not mean Americans won’t get to the Moon sooner however. I fully expect private enterprise to do it in less than a decade, and for far cheaper. Eventually the dunderheads in government will realize this, but we must give them time to realize it. Their brains work slowly.

FCC approves four proposed satellite constellations, including SpaceX’s of 7,500+

9:40 am

Capitalism in space: The FCC has approved licenses to launch four different proposed smallsat satellite constellations, totaling almost 8,000 satellites.

Of that total, more than 7,500 would belong to SpaceX’s proposed Starlink constellation.

The new regulatory approvals set the stage for two companies, SpaceX of Hawthorne, California, and Telesat of Ottawa, Canada, to expand constellations already approved last year with more satellites in the rarely used V-band spectrum. Canadian startup Kepler Communications and LeoSat, a company licensed from the Netherlands, also received approvals, Kepler for 140 Ku-band satellites and LeoSat for 78 Ka-band satellites.

Of the four, SpaceX is by far the largest with 7,518 satellites constituting what it calls a “very low Earth orbit,” or VLEO constellation that would operate slightly below 350-kilometers. At that altitude, SpaceX says atmospheric drag would pull spent satellites down in one month, assuaging concerns about the magnitude of debris that that many satellites could create in higher orbits.

While SpaceX likely plans to launch its satellites on its own rockets, the other companies will likely depend on the new smallsat rocket companies — Rocket Lab, Virgin Orbit, Vector — that are about to all come on line.

Escape velocity on Phobos changes a lot depending on location

9:34 am

A new computer analysis of the shape of the gravitational field of the Martian moon Phobos suggests that the escape velocity varies significantly, depending on where you are on the moon’s surface.

Phobos is an odd duck among our solar system’s moons. It’s tiny (a fraction of a percent the size of our own moon) and is shaped like a potato; that weird shape draws gravity to different places, depending on where you are.

All these features make Phobos a challenge to travel on, researchers report in Advances in Space Research. In some places, moving any faster than 5 kilometers per hour would be enough to free you from the moon’s meager gravitational pull, sending you off into space where you’d likely be captured by Mars’s gravity and end up orbiting the Red Planet. The fastest you could travel anywhere on Phobos would be about 36 kilometers per hour, or a little faster than a golf cart, the team finds.

Obviously, this must be recognized for any mission trying to land and explore the moon.

Rocket Lab raises an additional $140 million

9:29 am

Capitalism in space: Rocket Lab has raised an additional $140 million in investment capital following its successful first operational launch last week.

The company announced Nov. 15 that it closed a Series E funding round, led by existing investor Future Fund, an Australian sovereign wealth fund. Several other existing investors also joined the round, including Greenspring Associates, Khosla Ventures, Bessemer Venture Partners, DCVC (Data Collective), Promus Ventures and K1W1. One new investor, Accident Compensation Corporation of New Zealand, joined the round.

The Series E round comes after the company raised $75 million in a Series D round in March 2017. The company has now raised more than $288 million to date. Rocket Lab did not disclose the valuation of the latest round, but said it exceeded the “$1-billion-plus” valuation from its Series D round.

In the race to grab the smallsat market, Rocket Lab is far ahead of its nearest competitors, Virgin Orbit and Vector. If I had to rank them at this moment, I would say that Virgin Orbit is second with Vector third.

Defense offers much lower $5 billion Space Force cost

9:23 am

The deputy defense secretary yesterday said that the cost for creating a Space Force should be around $5 billion, not $13 billion as proposed by the Air Force.

The cost to create President Trump’s Space Force could be lower than $5 billion and certainly will be in the single-digit billions, Deputy Defense Secretary Patrick Shanahan said at a briefing Thursday, pushing back against Air Force estimates that put the price tag at $13 billion or more.

Shanahan, the lead Pentagon official working on the Space Force, expressed confidence the project would come to fruition — even though Democrats taking over the House have opposed it and the White House has broadly ordered the Pentagon to cut costs.

It appears that he is proposing that the military avoid the creation of a full-fledged new branch of the military and simply reorganize its space bureaucracy into a single office. This would not require Congressional approval, and is also what the military has been considering for the last few years.

Five billion however for an office still seems an ungodly amount of money to me. But then, this is how corrupt Washington functions.

Astronomers identify first progenitor star for Type 1C supernovae

3:27 pm

Astronomers have for the first time identified a progenitor star for a Type 1C supernovae.

[The search for supernovae progenitor stars has found] a few pre-supernova stars. But the doomed stars for one class of supernova have eluded discovery: the hefty stars that explode as Type Ic supernovas. These stars, weighing more than 30 times our Sun’s mass, lose their hydrogen and helium layers before their cataclysmic death. Researchers thought they should be easy to find because they are big and bright. However, they have come up empty. Finally, in 2017, astronomers got lucky. A nearby star ended its life as a Type Ic supernova. Two teams of researchers pored through the archive of Hubble images to uncover the putative precursor star in pre-explosion photos taken in 2007. The supernova, catalogued as SN 2017ein, appeared near the center of the nearby spiral galaxy NGC 3938, located roughly 65 million light-years away.

An analysis of the candidate star’s colors shows that it is blue and extremely hot. Based on that assessment, both teams suggest two possibilities for the source’s identity. The progenitor could be a single star between 45 and 55 times more massive than our Sun. Another idea is that it could have been a binary-star system in which one of the stars weighs between 60 and 80 times our Sun’s mass and the other roughly 48 solar masses. In this latter scenario, the stars are orbiting closely and interact with each other. The more massive star is stripped of its hydrogen and helium layers by the close companion, and eventually explodes as a supernova.

As can be seen by the quote above, identifying the star that exploded still leaves much unknown, including whether the star is a single or a binary. Still, they finally have some idea what kind of star erupts in a Type IIC supernovae, which will help constrain the theories for explaining the cause of these explosions.

Note also that this identification will not be confirmed until the supernova itself completely fades in about two years. They might find when that happens that the candidate progenitor is still there, meaning it was not the progenitor of the supernova at all.

Sixty documented-as-false anti-Trump news stories

9:11 am

Link here. A review of the sources for these stories show them coming mostly from the usual liberal news sources, places like CNN, the New York Times, the Washington Post, MSNBC, etc. I especially like #48:

48. May 28, 2018: The New York Times’ Magazine editor-in-chief Jake Silverstein and CNN’s Hadas Gold shared a story with photos of immigrant children in cages as if they were new photos taken under the Trump administration. The article and photos were actually taken in 2014 under the Obama administration.

Even after it was clearly documented that the fenced facilities were established during the Obama administration and that the Trump administration was simply continuing Obama policy in this area, these news organizations actually ramped up their coverage to make it seem as if Trump was the person who created this policy.

Liberals might wonder why Trump’s support remains strong, and rail against his crude attacks on the liberal press, but the bottom line remains: What he has been saying about the liberal press is largely true. They have stopped doing real reporting and have instead allowed their opposition to a Republican president to turn into blind hatred.

Moreover, Trump’s crude attacks have been a response to the left’s own crudeness and dishonesty, something the left refuses to admit to. And until we see a introspective reassessment by the liberal press, the crude attacks from both sides are only going to get worse.

India to attempt four more launches in 2018

8:50 am

The new colonial movement: In outlining the success of yesterday’s GSLV launch, the head of India’s space agency noted that they will attempt to complete four more launches before the end of the year.

Following the missions, Mr Sivan said, in January next, ISRO would launch the Chandrayaan-II mission (lunar lander) which will be the first operational mission of the GSLV-Mk III-vehicle.

Addressing reporters after the successful launch of the second developmental flight GSLV-MkIII-D2 carrying communication satellite GSAT-29, he said, “we have to achieve 10 missions before January.”

“That is six satellite missions as well as four launch vehicle missions. Definitely, the task in front of us is very huge,” he said.

According to him, after Wednesday’s flight, the heaviest launcher of India has completed its development flights and is entering into the operational group of launchers of ISRO, that is along with the PSLV (polar satellite launch vehicle) and GSLV.

Four launches in six weeks would require a launch every week and a half. IF ISRO can do this, they will demonstrate the ability to launch almost weekly, a capability that would place them close to becoming a world power in space.
