Exos suborbital reusable rocket aborts prematurely during third launch

10:07 pm

Capitalism in space: The third flight of Exos Aerospace’s reusable suborbital rocket SARGE was cut short today shortly after launch when the rocket had attitude control problems.

A reusable suborbital rocket developed by Exos Aerospace suffered a loss of attitude control seconds after liftoff on a test flight June 29, but the rocket was still able to glide safely back to Earth.

Exos’ Suborbital Autonomous Rocket with GuidancE, or SARGE, rocket lifted off from Spaceport America in New Mexico at about 2 p.m. Eastern. In the company’s webcast, the rocket started gyrating seconds after liftoff before disappearing from view.

Controllers were able to reestablish some control of the rocket, aborting the flight. The rocket deployed a drogue parachute and parafoil while venting unused propellant. The rocket slowly descended under that parafoil, landing within view of the launch pad 14 minutes after liftoff.

That it appears they were able to safely recover the rocket and its payloads is significant, even though this failure is a setback for the company.

Fascist mob sends journalist to emergency room in Portland

11:12 pm

They’re coming for you next: A fascist mob today attacked a journalist so violently today that they sent him to the emergency room.

Andy Ngo, a photojournalist and editor at Quillette, landed in the emergency room after a mob of antifa activists attacked him on the streets of Portland during a Saturday afternoon demonstration.

The assailants wore black clothing and masks, and were engaged in a counter-protest against several right-wing groups, including the Proud Boys. Ngo is a well-known chronicler of antifa activity, and has criticized their illiberal tactics on Fox News. He attended the protest in this capacity—as a journalist, covering a notable public event.

According to Ngo, his attacker stole his camera equipment. But video footage recorded by another journalist, The Oregonian’s Jim Ryan, clearly shows an antifa activist punching Ngo in the face. Others throw milkshakes at him:

It increasingly appears that Portland is now controlled by the modern version of the KKK, fascist hooded thugs who act to physically attack anyone who might be opposing them in any way at all. And like the KKK, these modern fascist thugs have deep links with the Democratic Party.

Meanwhile, the police and government in Portland does nothing.

Rocket Lab successfully completes third commercial launch in 2019

10:44 pm

Capitalism in space: Rocket Lab today successfully completed its third commercial launch in 2019, putting seven smallsats into orbit.

If you go to about 21 minutes into the video at the link you can watch the launch.

Rocket Lab is slowly shifting towards its goal of one launch per month leading to two launches per month by the end of the year. That this single somewhat tiny U.S. company (with many ties in New Zealand) now ties the nation of India, the world’s most populous democracy, and has more launches than well-established U.S. launch companies like ULA and Northrop Grumman speaks, volumes about the power of freedom and competition.

The leaders in the 2019 launch standings:

9 China
8 SpaceX
5 Russia
5 Europe (Arianespace)
3 India
3 Rocket Lab

The U.S. now leads China in the national rankings 14 to 9.

This will likely be the last launch in June. We are now at the year’s halfway point. The total number of launches in 2019 is 37, down from the 2018 count of 54. This suggests that the totals for entire year will also be less, but we shall see. As expected the drop is mostly due to fewer big satellite launches. However, if the smallsat launch companies begin to ramp up this year, as they have predicted, they could make up the difference.

Insight engineers get first look at hole

4:46 pm

InSight Mole hole
Click for full image.

The Insight engineering team has successfully lifted the mole structure allowing them to see the hole the mole was pounding into the Martian ground in their effort to diagnose why the mole has been unable to drill more than a foot or so down.

The image to the right shows the mole, the white tubelike structure, inside the hole. As noted by Instrument Lead Tilman Spohn,

I along with others from the team were a bit shocked when we saw how large the pit actually is. Its diameter is about two times the diameter of the mole. The bottom of the pit is difficult to see (we expect better images once the lift is complete) but it seems that it is about 2-2.5 mole diameters deep. A mole diameter is 27mm. So the mole must have compacted the regolith quite a bit. In addition to its own volume it must have displaced about half of its buried volume.

There seems to be a little rim surrounding the pit but most of the displacement likely was compaction. We cannot see the inclination of the wall very well but it at least seems to me that the mole was “precessing” (like a spinning top) and carved a conical hole. This is consistent with the recordings of our tiltmeter STATIL during the hammering in March. We will have to wait for better images to confirm or disprove that. In any case, the apparent compaction seems to be compatible with a large porosity, relatively low density.

What they do next is unknown. From what I understand, they do not have the option of lifting the mole out and trying a different location. Moreover, the images and data suggest it wouldn’t matter anyway. The mole is apparently not designed to drill a shaft in this kind of ground.

Seminar at Cornell will question use of “reason” and “rationality”

3:02 pm

The coming dark age: A six-week seminar this summer at Ivy League Cornell University will question the use of either “reason” and “rationality.”

The goal of the entire seminar is to demonstrate that knowledge, and truth, is always tied to power, which means that all knowledge, and truth, is entirely subjective, and if discovered by some ethnic groups in power (whites or Christians or Jews), other ethnic groups out of power have the right, the obligation, to reject that knowledge, and truth, in order to establish their own power base.

So, if an leftist Antifa fascist thug hits me, a white Jew, over the head with a rock and kills me, I can declare I am still alive because my interpretation of knowledge and truth is different than that leftist Antifa fascist thug.

Even more important, that leftist Antifa fascist thug will be justified in claiming he or she did nothing wrong, because from his or her perspective of knowledge and truth they did not kill me, but merely stopped me from oppressing them unjustly.

That dark age is coming on very fast. Be warned.

Hat tip Robert Pratt of Pratt on Texas.

Court reduces Oberlin total judgment by smallest amount

11:14 am

The court in Ohio has reduced the total jury award in the Oberlin slander case against Gibson’s Bakery to $25 million total, but by what looks like the smallest amount possible based on its interpretation of the law.

The jury originally returned a total compensatory verdict of $11 million and punitive verdict of $33 million. In these posts we detailed the arguments of the parties as to how to Ohio’s tort reform caps applied to the calculation:

The key disputes as to how to apply Ohio tort reform caps on noneconomic compensatory damages centered on whether each claim for each plaintiff was separately subject to the cap, or did the cap apply to all claims of each plaintiff. The court appears to have ruled, as plaintiffs argued, that the cap was per claim.

More significantly, the tort reform law limits punitive damages to 2X compensatory, but the issue was whether that applied to pre-cap compensatory damages or post-cap compensatory damages. That was about a $10 million swing. The court appears to have agreed with the plaintiffs argument that under the plain reading of the statute, the 2X cap applied to pre-cap compensatory damages.

Another way to put it is the court has awarded Gibson’s the maximum award possible based on its legal interpretation. To me, this suggests that the court is as offended as everyone else by Oberlin’s refusal to accept the decision while spreading falsehoods about the case and maligning the jury.

They will have a hearing on how much Oberlin will have to pay for Gibson’s attorney’s fees on July 10.

The travels of China’s Yutu-2 rover on the Moon

9:34 am

Yutu-2 and Chang'e-4
Click for full image.

The Lunar Reconnaissance Orbiter (LRO) science team today released images that track the travels of China’s lunar rover Yutu-2 from its landing on January 30, 2019 through June 3, covering the rover’s first six lunar days on the Moon.

The image to the right, cropped, reduced, and annotated to post here, shows the relative positions of both spacecraft as of June 3, 2019. In the release they also included a gif movie showing the progression of Yutu-2’s movements since landing.

Once a month, LRO passes over the Chang’e 4 landing site, allowing LROC to capture a new image. LROC has now imaged the site five times (since the landing) and observed Yutu-2 to have traveled a total of 186 meters (distance measured using the rover tracks). If you squint, portions of the rover tracks are visible as a dark path in the images from April, May, and possibly June.

table of Yutu-2's movements through June 2019

The LRO release also included a table showing the distance Yutu-2 has traveled with each lunar day, shown on the right. The table does not include the 23 meters (75 feet) the rover traveled on its sixth lunar day. My estimate yesterday that Yutu-2 was traveling an average of about a 100 feet per day, with the distances per day shrinking with time, seems largely correct. During the rover’s fourth and fifth lunar days it moved very little, either because they had found something very interesting they wanted to inspect more closely, or they were moving more cautiously as the rover’s life extended past its planned lifespan of three lunar days.

On the sixth day however they increased their travels again, suggesting that either they had finished the observations at the previous location, or they had gained more confidence in the rover’s staying power.

SpaceX seeking more investment capital

9:09 am

Capitalism in space: SpaceX has begun its third round of private fund-raising this year, this time seeking more than $300 million.

The latest round, filed on Monday, seeks to raise $314.2 million at a price of $214 a share, according to a document seen by CNBC. The new equity would bring SpaceX’s total 2019 fundraising to $1.33 billion once completed.

The block of this new round appears to already be funded from the Ontario Teachers’ Pension Plan.

Chaos on Mars

9:01 am

Aurorae Chaos in Margaritifer Terra
Click for full image.

The Mars Express science team today released a digital perspective view of the chaos terrain located in the outlet region for the vast drainages, which include Marineris Valles, coming down from the Tharsis Bulge volcanic region that holds Mars’ largest volcanos.

The view, reduced to post here on the right, was created from a image taken by Mars Express on October 31, 2018. This chaos terrain is south of the various examples of chaos terrain previously highlighted here on Behind the Black (May 14, 2018, June 26, 2018, March 11, 2019, March 14, 2019). As they note,

The division between the chaotic terrain and plains can also be seen clearly in these images. The left (south) side of the image is notably smoother and more featureless than the jumbled right (north) side, and the two regions are split by a prominent line carving diagonally across the frame. The transition area around this scarp is especially broken and fractured; this is thought to be caused as the martian crust stretched and moved.

…
The ancient chaotic terrain we see on Mars holds information about how water once permeated and interacted with the planetary surface, including how it was transported, stored, and released.

Chaotic terrain is thought to have formed as chunks of the martian surface collapsed in dramatic events triggered by the heating of material containing ice or water-bearing minerals – possibly due to climatic or volcanic heat sources, or an impact from an asteroid or comet. This released large amounts of water, causing the terrain above to subside. The water then drained away quickly, leaving behind the messy, broken patterns seen in regions such as Aurorae Chaos, which is thought to have formed some 3.5 billion years ago.

Mars Express images don’t quite have the resolution of the high resolution images from Mars Reconnaissance Orbiter, but they cover a wider area, so that the spacecraft has now photographed almost the entire Martian surface since its arrival in Mars orbit in December 2003.

TESS finds exoplanet smaller than Earth

10:08 pm

Worlds without end: TESS has now found an exoplanet somewhere between Mars and the Earth in size, and is part of a solar system with two other Earth-sized planets.

L 98-59b is around 80% Earth’s size and about 10% smaller than the previous record holder discovered by TESS. Its host star, L 98-59, is an M dwarf about one-third the mass of the Sun and lies about 35 light-years away in the southern constellation Volans. While L 98-59b is a record for TESS, even smaller planets have been discovered in data collected by NASA’s Kepler satellite, including Kepler-37b, which is only 20% larger than the Moon.

The two other worlds in the system, L 98-59c and L 98-59d, are respectively around 1.4 and 1.6 times Earth’s size. All three were discovered by TESS using transits, periodic dips in the star’s brightness caused when each planet passes in front of it.

None of these planets is considered in the habitable zone however. Instead, they experience solar energies comparable to Venus.
