Rocket Lab announces new launch date

Capitalism in space: Rocket Lab has announced a new launch window for the first operational launch of its Electron rocket, beginning on June 23 for fourteen days.

Those dates are based on New Zealand time. If they launch at the very beginning of this window it will occur on June 22 in U.S.

The two month delay was caused by a problem with a “motor control unit.” This has been replaced. In the interim they have also added two more commercial payloads to the rocket.

“The Democrat Party is committed to the New Rules. And the New Rules are tyranny.”

Link here. Schlicter goes on to say,

It can’t be a surprise. After all, the Democrat Party has bulldozed every norm, custom, and tradition out there in its quest for undisputed power. It spews hatred at its opponents – hey, everyone reading this is racist, sexist, and a denier of #science and so forth. The Democrats will happily deny you your free exercise of religion – put on your aprons people, because you can bake a cake or be bankrupted. They seek to suppress speech by encouraging fascism both in academia and by online tech companies, and if you think they won’t pass laws to limit speech given the chance, you’re fooling yourself. Hell, they tried to amend the First Amendment to overturn Citizens United, a case where the government tried to ban a movie critical of Hillary Clinton.

Let’s say that again, because it’s madness. The position of the left-of-center party in the United States is that the government should be allowed to arrest and imprison people for making a film critical of a politician.

He is also mirroring what I wrote here and here From the second link:

[T]he left and Democrats are becoming very nonchalant about demanding the nullification of the Constitutional rights of anyone who disagrees with them. This is not to be taken lightly. They mean it. Give them a victory in an election and they will begin to do it.

I have seen nothing in recent events to change that conclusion. If anything, the rise of radical socialism in the Democratic Party only reinforces it.

China launches two test cubesats to the Moon

The launch this week of a Chinese communications relay satellite to be used for its Chang’e-4 lunar lander also included the launch of two test cubesats designed to test such satellites in interplanetary space.

One of the two Longjiang (‘dragon river’) microsatellites that launched with Queqiao but set to operate together in lunar orbit, carries an optical microcamera (Arabic) developed by the King Abdulaziz City for Science and Technology (KACST) of Saudi Arabia.

The instrument weighs around 630 g and is capable providing images of the Moon with a resolution of 38 m per pixel at a perilune of 300 km and 88 m per pixel at the expected apolune of 9, 000 km away the lunar surface.

The Longjiang-1 and -2 satellites, developed by Harbin Institute of Technology (HIT) in Northeast China, will test low-frequency astronomy and space-based interferometry in lunar orbit. However, they also carry amateur radio payloads, meaning amateurs can send commands to take and download an image of the Moon using the KACST camera.

It seems that China is trying to compete with the U.S. in the development of interplanetary cubesats. The inclusion of an instrument developed in Saudi Arabia is also another indication that the new colonial movement in space continues to pick up steam.

Rogozin takes over Roscosmos

Former Deputy Prime Minister Dmitry Rogozin has now officially been named the head of Roscosmos.

It appears Rogozin will continue the Putin government’s policy of consolidating the entire aerospace industry into Roscosmos.

Along with the new appointment, the Russian press reported on Rogozin’s plans to initiate yet another reorganization of Roskosmos to absorb Tactical Rocket Armaments company, specialized in battlefield missiles, and, possibly, the Almaz-Antei enterprise, developing anti-aircraft and anti-missile systems.

This policy also suggests that Russia’s continuing fade as a major player in the international launch market will continue. They will focus on internal needs, but will no longer be able or willing to compete for business outside of Russia. Without any internal competition, and with corruption rife within these industries, Roscosmos under Rogozin will stumble along issuing press releases about future great projects, few of which will really happen, while it acts instead as a pork barrel jobs program for friends of Putin.

Can we trust any deal with North Korea?

Link here. The article, from the science journal Nature, is an interview with a South Korean nuclear expert who is very skeptical of any claims by North Korea that it has dismantled its nuclear program.

This skepticism seems reasonable to me. Consider the history. The Clinton administration signed a deal with North Korea (very similar in many ways with Obama’s Iran nuclear deal) that was supposed to prevent North Korea from getting the bomb. Instead, all it did was allow us to make believe it wasn’t happening, even as North Korea developed the technology and eventually completed several underground tests of nuclear bombs.

We shall see if Trump allows himself to get fooled, like Clinton. Right now, the indications are no. At the same time, it pays to be as skeptical of any politician as this South Korean nuclear expert is of North Korea. None of these power-hungry politicians can be trusted, even Trump. When the general public makes the mistake of trusting them it always gets screwed.

Update: Trump has canceled the summit with North Korea.

Satellite images of Iran’s missile program

Using images produced by the private satellite company Planet, experts have exposed Iran’s secret rocket program.

The images are fascinating and definitive. They even reveal what must be solid rocket motor test stands, with the ground scars left over after tests.

These pictures were the proof outlined in a recent news article that showed the joke that was the Iran nuclear deal.

ICBMs are not defensive weapons. They are by nature offensive weapons, used as a deterrent in some contexts, but the deterrent value lies in their offensive nature. They are designed to strike long distances away from borders and frontiers as a means of extending offensive capabilities. Paired with a nuclear-weapons program, they become an even greater offensive threat, one that would destabilize the entire region.

Defenders of the [nuclear deal] will argue that the deal eliminated the threat of that pairing, but that’s nonsense. Even if Iran abided by the terms of the [deal], it would only have had to wait ten years to produce a nuclear weapon. Having an ICBM platform available for a nuclear warhead to fit it would fit perfectly into a strategy of dominating the region by nuclear blackmail, and would force others in the region to develop or acquire their own systems to counter it.

This is just another reminder that we cut a deal with a terrorist state that didn’t do anything to restrict its terrorist or its ability to develop platforms for later use against us. If anything, the [nuclear deal] provided financial support for these efforts and others in the region, fueling conflict and pushing Iranian hegemony all the way to the Mediterranean, all without getting anything in return other than a piece of paper. We didn’t even get American detainees out of Iran. It’s a complete debacle, only becoming even more apparent with the passage of time.

But the leftist elitists who run our cultural and intellectual communities continue to think Trump is an idiot for pulling out of the deal. I ask, who is the real idiot here?

New NOAA weather satellite has serious problem

Can’t anybody here play this game? The cooling unit required to take infrared images in the new NOAA weather satellite GOES-17, launched in March, is not functioning properly.

“This is a serious problem,” Volz said Wednesday in a conference call with reporters. “This is the premier Earth-pointing instrument on the GOES platform, and 16 channels, of which 13 are infrared or near-infrared, are important elements of our observing requirements, and if they are not functioning fully, it is a loss. It is a performance issue we have to address.”

Detectors for the infrared channels must be cooled to around 60 Kelvin (minus 351 degrees Fahrenheit) to make them fully sensitive to infrared light coming from Earth’s atmosphere. For about 12 hours each day, the cooler inside the Advanced Baseline Imager, or ABI, is unable to chill the detectors to such cold temperatures, officials said.

Infrared images from weather satellites are used to monitor storms at night, when darkness renders visible imagery unavailable. The three visible channels from the ABI are not affected by the cooling problem.

“The other wavelengths, the near-infrared and infrared wavelengths — the other 13 — need to be cooled to some extent beyond the capability of the system at present,” said Tim Walsh, NOAA’s program manager for the GOES-R weather satellite series. “There’s a portion of the day centered around satellite local midnight where the data is not usable, and that’s what we’re addressing.”

GOES-17 is the second of a four satellite constellation being built by NOAA costing $11 billion.

It appears that an identical cooling system was installed on the first of this satellite constellation, GOES-16, and has been working perfectly in orbit since November 2016. Why the new unit isn’t working remains a puzzle.

The real issue here is the cost and complexity of these satellites. Because they are so complex and take so long to build, replacing them is difficult if not impossible. Wouldn’t it be better to launch many cheaper satellites to provide redundancy at a lower cost?

This is a pattern we see throughout the government aerospace industry. NASA’s Webb and WFIRST telescopes are big and take decades to build. God forbid they fail at launch. SLS and Orion are big and take decades to build. God forbid they fail at launch. The Air Force’s numerous military satellites are big and take decades to build. God forbid an enemy takes one out.

In all these cases, failure means we get nothing after spending a lot of time and money. And replacing the loss will take years and billions of dollars.

Common sense says it is time to rethink this entire operation. Unfortunately, this is the federal government. The concept of rethinking anything, or even thinking at all, is too often a completely alien concept. I do not expect anything to change, unless we elect new people in Congress and the Presidency who are willing to take a hammer to this whole insane system and smash it bluntly. Trump is kind of this type of new person, but even he isn’t willing to change that much, only some things, such as the EPA, that irk him in particular. Otherwise, he has left much of the federal bureaucracy alone — as can be seen by his administration and NASA both gearing up to fund both LOP-G and WFIRST— thus continuing this pattern of big and expensive projects that take forever to build.

Mars rover update: May 23, 2018

Summary: Curiosity drives down off of Vera Rubin Ridge to do drilling in lower Murray Formation geology unit, while Opportunity continues to puzzle over the formation process that created Perseverance Valley in the rim of Endeavour Crater.

For a list of past updates beginning in July 2016, see my February 8, 2018 update.

Curiosity's travels on and off Vera Rubin Ridge

For the overall context of Curiosity’s travels, see Pinpointing Curiosity’s location in Gale Crater.

Since my April 27, 2018 update, Curiosity has continued its downward trek off of Vera Rubin Ridge back in the direction from which it came. The annotated traverse map to the right, cropped and taken from the rover’s most recent full traverse map, shows the rover’s recent circuitous route with the yellow dotted line. The red dotted line shows the originally planned route off of Vera Rubin Ridge, which they have presently bypassed.

It appears they have had several reasons for returning to the Murray Formation below the Hematite Unit on Vera Rubin Ridge. First, it appears they wanted to get more data about the geological layers just below the Hematite Unit, including the layer immediately below, dubbed the Blunts Point member.

While this is certainly their main goal, I also suspect that they wanted to find a good and relatively easy drilling candidate to test their new drill technique. The last two times they tested this new technique, which bypasses the drill’s stuck feed mechanism by having the robot arm itself push the drill bit against the rock, the drilling did not succeed. It appeared the force applied by the robot arm to push the drill into the rock was not sufficient. The rock was too hard.

In these first attempts, however, they only used the drill’s rotation to drill, thus reducing the stress on the robot arm. The rotation however was insufficient. Thus, they decided with the next drill attempt to add the drill’s “percussion” capability, where it would not only rotate but also repeatedly pound up and down, the way a standard hammer drill works on Earth.

I suspect that they are proceeding carefully with this because this new technique places stress the operation of the robot arm, something they absolutely do not want to lose. By leaving Vera Rubin Ridge they return to the more delicate and softer materials already explored in the Murray Formation. This is very clear in the photo below, cropped from the original to post here, showing the boulder they have chosen to drill into, dubbed “Duluth,” with the successful drill hole to the right.

Drilling success for Curiosity

For the first time in more than a year, Curiosity has successfully used its drill to obtain a sample from beneath the surface of Mars.

Curiosity tested percussive drilling this past weekend, penetrating about 2 inches (50 millimeters) into a target called “Duluth.”

NASA’s Jet Propulsion Laboratory in Pasadena, California, has been testing this drilling technique since a mechanical problem took Curiosity’s drill offline in December of 2016. This technique, called Feed Extended Drilling, keeps the drill’s bit extended out past two stabilizer posts that were originally used to steady the drill against Martian rocks. It lets Curiosity drill using the force of its robotic arm, a little more like the way a human would drill into a wall at home.

I plan to post a rover update either today or tomorrow, with more details about this success. Stay tuned!
