In the United States: the first rocket launched from a 3D printer

Status: 03/23/2023 09:07 AM

The first launch of an almost entirely 3D-printed rocket ended after just three minutes. During the first test flight, „Terran 1” did not reach orbit as planned. Shortly after takeoff, it fell into the sea.

The world’s first 3D-printed rocket didn’t reach orbit for its first test flight as planned. The unmanned Terran 1 took off from the launch pad at Cape Canaveral in the US state of Florida – but it did not reach the hoped-for altitude and crashed into the Atlantic Ocean after about three minutes of flight time.

The first stage lifted off after launch from the Space Force’s Cape Canaveral Station as planned. The upper stage also initially ignited, but then stopped, causing the rocket to fall into the sea. It was already planned that „Terran 1” will reach low Earth orbit in eight minutes. The test flight aboard Relativity Space was only the company’s first 3D-printed metal product six years ago.

The operating company is still satisfied

According to Relativity Space, the goal of the first test flight was to collect data and show that a 3D-printed rocket can withstand the pressure of launch and flight. According to the operating company, this was a success: Relativity Space wrote on Twitter that the launch of „Terran 1” confirmed the technology and would enable the launch of the next rocket, „Terran R”. This is the biggest evidence of the new approach to additive manufacturing, the letter continues.

Made of alloy

According to the California company Relativity Space, „Terran 1” is the largest object ever produced using a 3D printer. Most of the tree parts for the 33-meter rocket, including the engines, came from the company’s giant 3D printers in Long Beach, California. According to the manufacturer, 85 percent of the „Tiran-1” missile consists of 3D-printed metal parts. The larger versions should have a higher percentage and be reusable many times.

Other aerospace companies are also using 3D printing, but parts make up only a small part of their rockets. Founded in 2015 by two young aerospace engineers, Relativity Space has attracted the attention of investors and venture capitalists.

Migrants from Senegal: “Nothing works in this country”

Migrants from Senegal: “Nothing works in this country”

As of: May 12, 2024 at 2:31 p.m

The number of people from West Africa heading to Europe has increased significantly. Not only do they want to escape poverty, they also want to feel a lack of prospects.

Written by Kay Costner, Ard Rabat

Sheikh Ndaw, 24, just wants to leave. Although the young mechanic has a job, nothing can stop him in Senegal: “I have my job, I work every day, but nothing works.” “Nothing works in this country.” His declared goal is Europe. And he already knows how to get there: by boat. From the point of view of the young Senegalese man, there is no other way out: “The only option is to go there illegally. Because I cannot afford the legal way, the plane.”

This makes the young man a very typical case for his generation. At least this is what migration researcher Professor Ali Tandian of Gaston Berger University in Saint Louis in northern Senegal sees. It is naive to think that most people leave their country in search of work, says Tandiyan.

Poverty is by no means the only reason

It’s more complicated, and the reasons are more complex: „Research shows us that those who migrate are not as poor as you think,” Tandiyan explains. “They are people who work. But they work for others so that the profits do not come back to them. Or they are people who are forced to do multiple jobs.”

Tandiyan talks about the so-called “working poor.” Indeed, statistics indicate that the poorest of the poor in Africa do not have the strength or means to undertake the long, often life-threatening journey – let alone pay the smugglers.

So it’s the people with the least limited resources who get going. The data also shows that the number of migrants leaving their homes within Africa is several times higher than the number heading to Europe in often small wooden fishing boats.

The number of immigrants is increasing rapidly

However, 13,000 people arrived in the Canary Islands via the so-called North Atlantic Route in the first three months of this year, five times the number of people the previous year. Many of them are from Senegal.

Most are driven by desperation — or by dreaming of a better future in their heads, says migration expert Tandiyan. “With all the illusions, the heroism of immigration and the glorification of travel for immigrants, people think it’s possible to find their way around once you’re gone.”

When Tandean talks about “delusions” and “glorification,” he is referring to a social media phenomenon that has been giving Europeans headaches for years: young immigrants and influencers in North Africa have repeatedly filmed themselves in TikTok photos and videos, smiling and smiling completely. On their perilous journeys in small boats across the Mediterranean.

They stood relaxed in front of their smartphone cameras and acted as if it was a harmless fun ride with a glorious future waiting beyond the horizon. And not about a flight that kills thousands every year.

Many films that appeared years ago have now been deleted. But this does not solve the problem. In West Africa too, these posts, often shared hundreds of thousands of times, may still haunt the minds of many young people.

Will the new government change anything?

Regarding Senegal’s youth, aspirants took power at the beginning of April: “I often tell young people: the solution is not to ride boats.” Politician Ousmane Sonko addressed his young countrymen with these words in 2019. Sonko is well respected, especially among young Senegalese, and served as prime minister for a few weeks after his party colleague Diomai Fay won the presidential election in a landslide.

You now have the opportunity to make a difference. The main tasks they set for themselves are: job creation; Improving the conditions of rural residents and fishermen; Curb inflation.

„Immigration is not yet on our politicians’ agenda,” criticizes Tandiyan. Senegal’s newly elected government, celebrated by many young people, now has the opportunity to change that. The big question is whether she will.

Sheikh Ndaw, 24, doesn’t want to wait for an answer. He is ready to risk his life and leave Senegal by boat to Europe.

WABC radio in New York fired Giuliani, who is close to Trump. He is said to have repeatedly spread lies about the 2020 US election.

WASHINGTON — Rudy Giuliani is no longer allowed to speak on conservative radio station WABC in New York. The lawyer and former mayor of New York, who is close to Donald Trump, has repeatedly spoken of Joe Biden’s victory being rigged in the 2020 US election. There is no evidence of that, says John Catsimatidis, owner of WABC Radio – and draws conclusions.

We warned him once. We warned him twice.” The New York Times. Giuliani refused to avoid the topic of the 2020 US elections and thus had no choice but to suspend him. “Look, I like the guy as a person, but you can’t do that.”

Giuliani suspects censorship because he is not allowed to talk about election fraud on the radio

Meanwhile, Giuliani feels his freedom of expression is being restricted, so he spread the word about the 2020 US presidential election. He also urged his followers to contact the radio station and ask if they support freedom of expression.

Giuliani and other Trump supporters spoke out about censorship after the incident. For example, right-wing politician and Trump adviser Steve Bannon accused the radio station, which also broadcasts on Channel X, of stabbing the entire MAGA (Make America Great Again) program in the back. For radio chief Catsimatidis, there seems to be no going back on his decision. Question for guardianWhen asked if he could envision working with Giuliani in the future, he said no.

Giuliani served as mayor of New York from January 1994 until the end of December 2001, and was one of the Republican Party’s candidates to succeed US President George W. Bush. After Trump’s defeat by Biden in the 2020 US elections, the lawyer became a central figure in Trump’s attempts to overturn the election result.

Giuliani has repeatedly publicly defended the theory that the election was tampered with, and was subsequently ordered by a US court to pay $148 million.

Putin’s soldiers demand the use of an old weapon in the Ukraine war

Ukrainian kamikaze drones are increasing casualties among Russian forces in a particularly brutal way. The soldiers turn to Putin pleadingly.

Donbass – They came on the orders of Kremlin autocrat Vladimir Putin. Many of them remain in Ukraine as other victims of Russia. As of early May 2024, more than 450,000 Russian Army soldiers have been killed or wounded in the Ukraine war. This was reported by the British Ministry of Defense in London, which is closely monitoring the situation. According to French estimates, at least 150,000 of these soldiers are no longer alive.

Russia’s losses: Drones wreak havoc on Putin’s army in Ukraine war

One of the reasons for the heavy losses suffered by the Russian Armed Forces in the Ukraine war: the treacherous drones used by the Ukrainians. Russian soldiers have now literally turned to the Kremlin regime and demanded an ancient weapon.

Casualties in the Ukraine war: Russian soldiers demand anti-drone rifles

A video is circulating on X (formerly Twitter) showing two Russian soldiers fighting a Ukrainian drone. Finally one of the soldiers destroys the drone with a rifle blast. Its model looks quite modern, but rifles are also available in older versions – from the 17th century.

“We need rifles, we need rifles!” “These drones are a real problem for us and we are struggling to find an effective way to control them to ward them off,” a Russian soldier recently declared in a video that went viral on social media. “We are tired of them, these damn drones! The gun saves the lives of ten people, „If not more. They’re just shooting at us.” The soldier’s photo looks like a cry for help in the Ukraine war, as if he were asking civil society to raise money to buy rifles because the Russian army is abandoning its soldiers again?

Vladimir Putin’s losses: Russian soldiers fear Ukrainian drones

Another Russian soldier appears in an American news magazine Newsweek “Drones are a constant nuisance and we have no ways to deal with them,” he was quoted as saying. Will rifles be a decisive factor for us on the ground to minimize casualties against Ukrainian forces? Ukrainian military bloggers frequently post videos on social networks about how Russian soldiers are directly attacked by suicide drones, or how drones drop grenades on them. In such cases there is often no escape for them.

Why guns? In the modern defense industry, the so-called air burst ammunition is based on this. In this case, the ammunition is exploded in the air by a detonation charge and releases many small fragments over a large radius. This creates a veritable cloud of shrapnel or submunitions. Shotguns work similarly, and also fire ammunition that disperses through the air over a large radius, greatly increasing the likelihood of hitting flying targets – such as drones.

Russia’s losses in the Ukraine war: Kamikaze drones have become dangerous for tanks

Since the T-72, T-80 and T-90 battle tanks on the Russian side, as well as Ukrainian Leopard 2 and M1 Abrams tanks, have proven vulnerable to suicide drones, the Western arms industry is at least pushing to develop protection systems. Remotely active such as Trophy. These also fire shrapnel at lightning speed in order to neutralize an approaching projectile with a sort of ammunition cloud. Which again resembles the traditional single soldier rifle.

As the Russian army advances towards Chasiv Yar in the Donbass region west of Bakhmut, a Ukrainian soldier, among others, called for more reactive armor for Abrams tanks due to the threat of drones – just to name a few. Both sides often link the old but powerful RPG-7 anti-tank grenade to drones for tank combat. Or, as harsh as it may sound, using it to hunt down individual soldiers. (evening)
