The Top Fell Off Australia's First Orbital-Class Rocket, Delaying Its Launch

1 Comment
Australia's first orbital-class rocket launch was delayed after the nose cone of Gilmour Space's Eris rocket unexpectedly detached due to an electrical fault during final preparations. Although no damage occurred and no payload was onboard, the company is postponing the launch to investigate and replace the fairing before attempting another test flight. Ars Technica reports: Gilmour, the Australian startup that developed the Eris rocket, announced the setback in a post to the company's social media accounts Thursday. "During final launch preparations last night, an electrical fault triggered the system that opens the rocket's nose cone (the payload fairing)," Gilmour posted on LinkedIn. "This happened before any fuel was loaded into the vehicle. Most importantly, no one was injured, and early checks show no damage to the rocket or the launch pad."

Gilmour was gearing up for a launch attempt from a privately owned spaceport in the Australian state of Queensland early Friday, local time (Thursday in the United States). The company's Eris rocket, which was poised for its first test flight, stands about 82 feet (25 meters) tall with its payload fairing intact. It's designed to haul a payload of about 670 pounds (305 kilograms) to low-Earth orbit.

While Gilmour didn't release any photos of the accident, a company spokesperson confirmed to Ars that the payload fairing "deployed" after the unexpected electrical issue triggered the separation system. Payload fairings are like clamshells that enclose the satellites mounted to the top of their launch vehicle, protecting them from weather on the launch pad and from airflow as the rocket accelerates to supersonic speeds. Once in space, the rocket releases the payload shroud, usually in two halves. There were no satellites aboard the rocket as Gilmour prepared for its first test flight.
The report notes that the Eris rocket is aiming to "become the first all-Australian launcher to reach orbit."

***REVISED RECIPE, MAKES A HALF DOZEN***

1 tablespoon butter, plus more for the pan
1 tablespoon sugar
1 egg
1-2 teaspoons vanilla
1 cup milk (or maybe more)
1 tablespoon cornstarch
1/2 teaspoon kosher salt
1/4 teaspoon baking soda
1 teaspoon baking powder
1 1/2 cups all-purpose flour (or maybe less)

Melt the butter, then mix in the sugar to cool it down. Stir in the egg until smooth, then the vanilla and the milk — enough milk to get you 1 1/2 cups total liquid. Stir in the starch, salt, baking soda, baking powder and flour — enough flour to get the thickness you want (see video). Mix until the batter is almost but not entirely smooth (see video). Rest the batter at least 15 minutes before you cook.

Heat a nonstick pan until butter browns but not very rapidly. Smear the pan with butter, then use a towel to smear a little batter all over the pan to create a thin film — wipe off until almost clean. (This will get you more even color on your first batch of pancakes.) No additional butter is needed if you're cooking on teflon. Cook the pancakes until you see bubbles and the bottom has solidified and browned, then flip and finish the other side.

Germany’s Cabinentaxi: The Double-Sided Monorail That Wasn’t Meant To Be

1 Comment

The 1970s was a perfect time for alternative modes of transport to be trialed that might replace cars in the wake of the global oil crisis. One of these was the Cabinentaxi, or C-Bahn as it was later called, which was a variation on the standard suspended and monorail concepts.

It was a people mover concept, with ‘pods’ (or cabins) that’d ride either on top of or below the suspended track. It was tested intensively over the course of six years, performed admirably, and completely failed to materialize commercially due to budget crunch times around the world.

Recently [Tim Traveller] went to the muddy farm field that once housed the big test track (pictured above), of which nothing remains but the gates and a sign. Despite the fact that few people have heard of Cabinentaxi prior to seeing [Tim]’s video or reading this, there is a big Wikipedia entry on it, as well as a (German language) site dedicated to the technology.

What made the C-Bahn different from trains and buses were the smaller pods, high throughput capacity and ability to call a pod on demand at any of the stations. This kind of flexibility is what is seen more or less with today’s people moving systems at airports and some cities, except the C-Bahn was classified as a personal rapid transport (PRT), with on-demand pods that could travel between any two stations without stopping or delays. This is something that isn’t seen with public transport today, even if self-driving cars purport to one day do this kind of trick.

Considering that this technology died most due to economical circumstances, we remain hopeful to see its revival one day.
