German rocket startup Hyimpulse’s first suborbital rocket arrives in Australia

9:32 am

The German rocket startup Hyimpulse today announced that its first suborbital rocket, the SR75, had arrived in Australia for its planned first test launch.

On 28 February, Southern Launch, the commercial outfit that manages the Koonibba Test Range, revealed that a launch attempt of the suborbital SR75 rocket would occur between late April and early May. This likely gives the team little room for the unexpected as it prepares for launch.

Those launch dates depend on whether Australia’s government will issue the launch licenses on time. So far its ability to do so in a timely manner has been difficult if not impossible. For example, the rocket startup Gilmour, which wants to launch from Bowen at about the same time, has been waiting more than two years to get its approval, delaying its first orbital test launch by more than a year.

PLD Space announces its upcoming plans

9:22 am

Capitalism in space: Having received in late January a $43.5 million grant, bringing its total funding to more than $120 million, the Spanish rocket startup PLD Space today announced its upcoming plans.

[T]he company intends to inaugurate the first serial space rocket factory in Spain in mid-2024. The facilities will also enable vertical integration of the launchers. The industrial site, whose building work is already underway, will house the factory for the first MIURA 5 units [the company’s orbital rocket] as well as the company’s head offices. In total, PLD Space will be able to count on 18,400 square metres of industrial facilities in Elche (Alicante).

…Also scheduled for 2024, construction work is to begin on the launch base at the European CSG spaceport in Kourou (French Guiana), which belongs to CNES [France’s space agency]. This site, covering over 15,700 square metres, will host MIURA 5’s first launches.

That France is now leasing launch facilities to private companies illustrates starkly how Europe is steadily abandoning Arianespace, the European Space Agency’s government-run commercial company. Instead, Europe is now choosing competition and private enterprise as its model. Expect these new companies, including PLD, to achieve big things in the coming years.

Voyager-1 back on line after software patch works

9:09 am

For the first time since November, Voyager-1 is sending data back to Earth coherently, after engineers figured out a way to isolate a corrupted computer chip.

The team discovered that a single chip responsible for storing a portion of the FDS memory — including some of the FDS computer’s software code — isn’t working. The loss of that code rendered the science and engineering data unusable. Unable to repair the chip, the team decided to place the affected code elsewhere in the FDS memory. But no single location is large enough to hold the section of code in its entirety.

So they devised a plan to divide the affected code into sections and store those sections in different places in the FDS. To make this plan work, they also needed to adjust those code sections to ensure, for example, that they all still function as a whole. Any references to the location of that code in other parts of the FDS memory needed to be updated as well.

The software patch was sent to the spacecraft on April 18, 2024, taking 22.5 hours to get there. It then took 22.5 hours for a response. On April 20th they received a confirmation that the patch had worked. Over the next few weeks more patches will be sent to Voyager-1 to allow it to resume sending science data back to Earth.

Both Voyager-1 and Voyager-2 were launched almost a half century ago, in 1977, and both are now more than more than 15 billion miles from Earth, traveling in interstellar space. Their computers are also the longest continuously running operating systems. Both only have a little more than two years left in their nuclear power supply, which was always expected to run out of power about a half century after launch. That both have continued to function for that entire time is a magnificent testament to the engineers who designed them.

On the left, certainty and violent passion; On the right, doubt and fearful timidity; This must change!

What the left wants to destroy
What the left wants to destroy

“If you will not fight for right when you can easily win without blood shed; if you will not fight when your victory is sure and not too costly; you may come to the moment when you will have to fight with all the odds against you and only a precarious chance of survival. There may even be a worse case. You may have to fight when there is no hope of victory, because it is better to perish than to live as slaves.” ― Winston S. Churchill

It is said that if you want to win a war, it is essential to know your enemy almost better than you know yourself, so that you know what will be required of you to win.

Americans, those who still believe in the Constitution and the basic values of our country — limited government and the right of each individual to life, liberty, and the pursuit of happiness — routinely still think they are in the majority, that given a fair fight they will always win against the fascists of the left because the general public will immediately recognize the justice of the right’s cause.

This is not only a grave error, it is an error that Americans have been making for decades. Year by year since the 1960s Americans of all stripes have been unwilling to fight for right when it could have been easily won without bloodshed. Now bloodshed is almost certainly required, and the right continues to be unwilling to fight hard. Instead it still thinks its victories can be won easily, and so it is lazy about fighting those battles.

The left

To understand best why the right continues to lose, we first have to look closely at the left. As a movement, it has for decades been passionate and unwilling to compromise. Its leaders and followers are filled with certainty, and have been willing to do whatever is necessary to win.

Patchy arms in a nearby spiral galaxy

9:16 am

Patchy arms in spiral galaxy
Click for original image.

Cool image time! The photo to the right, reduced and sharpened to post here, was taken by the Hubble Space Telescope to study this southern hemisphere galaxy in detail. The galaxy, dubbed ESO 422-41, is located about 34 million light years away, and thus is a relatively close neighbor. From the caption:

A spiral galaxy, with a brightly shining core and two large arms. The arms are broad, faint overall and quite patchy, and feature several small bright spots where stars are forming. A few foreground stars with small diffraction spikes can be seen in front of the galaxy.

The patchy nature of the two arms makes each somewhat indistinct, so that at first glance this galaxy looks more like a elliptical blob, until you look close and notice those arms winding around that bright core. And as patchy as those arms are, the patches of blue are regions where new stars are forming.

China launches “remote-sensing” satellite

10:41 am

China today successfully launched what its state-run press stated was “a remote-sensing” satellite, its Long March 2D rocket lifting off from its Xichang spaceport in southwest China.

No other information about the satellite was released. The state-run press also provided no information about where the rocket’s lower stages, which carry very toxic hypergolic fuels, crashed within China.

The leaders in the 2024 launch race:

41 SpaceX
16 China
6 Russia
4 Rocket Lab

American private enterprise still leads the rest of the world combined in successful launches 47 to 28, while SpaceX by itself still leads the rest of the world, including other American companies, 41 to 34.

Computer models suggest there is no life in Europa’s underground ocean

11:22 am

The uncertainty of science: Several different computer simulations now suggest that the underground ocean inside the Jupiter moon Europa is inert and likely harbors no existing lifeforms.

He and his colleagues constructed computer simulations of Europa’s seafloor, accounting for its gravity, the weight of the overlying ocean and the pressure of water within the seafloor itself. From the simulations, the team computed the strength of the rocks about 1 kilometer below the seafloor, or the stress required to force faults in the seafloor to slide and expose fresh rock to seawater.

Compared with the stress applied to the seafloor by Jupiter’s gravity and by the convection of material in Europa’s underlying mantle, the rocks comprising Europa’s seafloor are at least 10 times as strong, Byrne said. “The take home message is that the seafloor is likely geologically inert.”

A second computer model also suggested that the moon’s deep magna is not capable to pushing upward into that sea, further reinforcing the first model that the sea is geological inert, lacking the heat or energy required for life.

Though unconfirmed and uncertain, these results when looked at honestly make sense. Europa is a very cold world. An underground ocean might exist due to tidal forces imposed by Jupiter, but that dark and sunless ocean is also likely to be very hostile to life. Not enough energy to sustain it.

Like the water imagined to exist at poles of the Moon, we go to Europa on the hope of finding life, even if that hope is very ephermal.

Update on SpaceX’s preparations for the 4th test flight of Superheavy/Starship

11:10 am

Link here. The article is definitely worth reading, as it tells us that SpaceX is pushing hard to be ready to launch in early May, as Musk has promised. The article also thinks SpaceX will be able to ramp up later launches to one every two months.

The article however is I think being naively optimistic about this timeline, because it naively assumes the FAA will quickly approve the launch licenses to meet that schedule. I guarantee the FAA won’t, as it has taken it one to four months after SpaceX was ready to launch to approve the licenses for the previous launches. The length of that approval process has shrunk each time, but FAA still made Space X wait each time, for no reason.

Making that schedule even more unlikely is SpaceX’s desire to do as many as nine test launches per year at Boca Chica. While the company could certainly do this, the environment reassessment issued in 2022 limits it to only five launches per year. It needs a waiver from the FAA and the Biden administration,
a waiver no one should expect considering the Biden administrations hostility to Musk.

Slovenia signs Artemis Accords

10:58 am

NASA announced yesterday that Slovenia has become the 39th nation to sign the Artemis Accords, joining the American alliance for exploring the Moon and the solar system.

The alliance now includes these nations: Angola, Argentina, Australia, Bahrain, Belgium, Brazil, Bulgaria, Canada, Columbia, Czech Republic, Ecuador, France, Germany, Greece, Iceland, India, Israel, Italy, Japan, Luxembourg, Mexico, the Netherlands, New Zealand, Nigeria, Poland, Romania, Rwanda, Saudi Arabia, Singapore, Slovenia, South Korea, Spain, Sweden, Switzerland, the United Kingdom, the United Arab Emirates, the Ukraine, the United States and Uruguay.

As with all the recent announcements, the NASA press release now insists that the accords are designed to “reinforce and implement key obligations in the 1967 Outer Space Treaty,” the exact opposite of the original goals of the accords. Rather than overvcome the Outer Space Treaty’s restriction on private property in space, the Biden administration is now using the accords to strengthen that restriction. To quote someone (Mussolini) whose policies the modern globalist world clearly admires, “Everything in the State, nothing outside the State, nothing against the State.”

This could all change with different leadership in Washington, but whether the administrative state, led by the Democratic Party, will allow such a thing at this point in history is very questionable. And they appear aided in this totalitarian effort by a meek and largely ignorant American public.
