If and when we ever get an asteroid mining industry off the ground, one of the most important decisions to be made in the structure of any asteroid mining mission would be how to get the resources back to where all of our other infrastructure is – somewhere around the Earth. That decision typically will focus on one of two propulsion methodologies – chemical rockets, such as those we already use to get us into space in the first place, or solar sails, which, while slower and unable to get us into orbit, don’t require any fuel. So, which propulsion methodology is better for these future missions? A study by researchers at the University of Glasgow looked at those two scenarios and came out with a clear-cut answer – solar sails.Continue reading “Are Chemical Rockets or Solar Sails Better to Return Resources from Asteroids?”
The New Ariane 6 Heavy Lift Rocket is Finally on the Launch Pad, But Won’t Liftoff Until Late 2023
A prototype of ESA’s new heavy lift rocket is now fully assembled and sitting on the launchpad at Europe’s Spaceport in French Guiana. But according to officials at a briefing last week, the space agency and the rocket’s prime contractor, ArianeGroup, have decided to delay the first flight of the Ariane 6 to the fourth quarter of 2023 after several issues were brought to the fore in an external review.Continue reading “The New Ariane 6 Heavy Lift Rocket is Finally on the Launch Pad, But Won’t Liftoff Until Late 2023”

Musk Suggests That Starship Will Probably Make an Orbital Flight in November
SpaceX Founder and CEO Elon Musk recently took to Twitter and hinted that the much-anticipated Starship—currently undergoing upgrades in preparation for its upcoming maiden flight—could launch as soon as November.
Responding to a question from a curious Twitter account asking about updates for Starship’s orbital flight date, Musk responded, “Late next month maybe, but November seems highly likely. We will have two boosters & ships ready for orbital flight by then, with full stack production at roughly one every two months.” As usual, his tweet garnered thousands of likes and hundreds of retweets.Continue reading “Musk Suggests That Starship Will Probably Make an Orbital Flight in November”
More Rocket Launches Could Damage the Ozone Layer
There are few things in this world that brings feelings of awe and wonder more than a rocket launch. Watching a literal tower of steel slowly lift off from the ground with unspeakable power reminds us of what humanity can achieve despite our flaws, disagreements, and differences, and for the briefest of moments these magnificent spectacles are capable of bringing us all together regardless of race, creed, and religion.Continue reading “More Rocket Launches Could Damage the Ozone Layer”
In a Comprehensive new Test, the EmDrive Fails to Generate any Thrust
The EmDrive is a hypothetical rocket that proponents claim can generate thrust with no exhaust. This would violate all known physics. In 2016, a team at NASA’s Eagleworks lab claimed to measure thrust from an EmDrive device, the news of which caused quite a stir. The latest attempt to replicate the shocking results has resulted in a simple answer: the Eagleworks measurement was from heating of the engine mount, not any new physics.Continue reading “In a Comprehensive new Test, the EmDrive Fails to Generate any Thrust”
This Rocket Engine’s Thrust Chamber was 3D-printed and Only has Three Parts
This week, European engineers hot-fire tested a fully 3D-printed thrust chamber that could one day power the upper stages for rockets. The chamber has just three parts, and was constructed using additive layer manufacturing, another name for 3D printing.
This hot-fire test lasted 30 seconds and was carried out on May 26, 2020 at the DLR German Aerospace Center’s Lampoldshausen testing facility. The European Space Agency said that additional tests are planned for next week.Continue reading “This Rocket Engine’s Thrust Chamber was 3D-printed and Only has Three Parts”
Every Part of Blue Origin’s New Glenn Rocket is Gigantic, Including its Nose Cone
Massive. Enormous. Huge. Gigantic. And whatever other words you find in the thesaurus all do the job when it comes to describing Blue Origin’s New Glenn Rocket. Especially its nosecone.Continue reading “Every Part of Blue Origin’s New Glenn Rocket is Gigantic, Including its Nose Cone”
A New Kind of Rocket that’s Lightweight and Easier to Construct: a Rotating Detonating Engine. Unfortunately, it’s Also Completely Unpredictable
In the current era of space exploration, the name of the game is “cost-effective.” By reducing the costs associated with individual launches, space agencies and private aerospace companies (aka. NewSpace) are ensuring that access to space is greater. And when it comes to the cost of launches, the single-greatest expense is that of propellant. To put it simply, breaking free to Earth’s gravity takes a lot of rocket fuel!
To address this, researchers at the University of Washington recently developed a mathematical model that describes the workings of a new launch mechanism: the rotating detonation engine (RDE). This lightweight design offers greater fuel-efficiency and is less complicated to construct. However, it comes with the rather large trade-off of being too unpredictable to be put into service right now.Continue reading “A New Kind of Rocket that’s Lightweight and Easier to Construct: a Rotating Detonating Engine.

Watch NASA Test an SLS Tank to Destruction
By the time a rocket actually launches, it’s components have been through a ton of rigorous testing. That’s certainly true of NASA’s SLS (Space Launch System) which is the most powerful rocket ever built. That’s right, something is finally going to surpass the Saturn V, the rocket that took Apollo astronauts to the Moon.Continue reading “Watch NASA Test an SLS Tank to Destruction”
Japan’s First Private Rocket Flies to Space
Have you heard of Interstellar Technologies? They’re the latest private company to launch their own rocket into space. They’re a Japanese company, and like other private space companies, their stated goal is to lower the cost to access space.Continue reading “Japan’s First Private Rocket Flies to Space”
