Science fiction met space fact this week in the Seattle area when the cast of “The Expanse,” the science-fiction jewel in Amazon’s streaming-video crown, got a look at Blue Origin’s spaceship.

Amazon CEO Jeff Bezos is the common denominator in the meetup: He personally engineered the sci-fi series’ shift from SyFy to Prime Video, and announced it onstage at a space conference last May while I was sitting beside him. Bezos is also the founder of Blue Origin, the space venture that is testing its New Shepard suborbital spaceship and gearing up to build its orbital-class New Glenn rocket.

During last May’s sit-down with Bezos, I joked that cast of “The Expanse” might want to take a ride on New Shepard, just to get some real-life experience behind their portrayal of space travel. And Bezos played along.

Rocket Lab has successfully launched its first rocket of 2019, a mission for the U.S. Defense Advanced Research Projects Agency (DARPA) that will test a novel method to deploy a satellite antenna in orbit.

The Electron rocket carrying the single satellite lifted off today, Thursday, March 28 from the company’s Launch Complex 1 on the Māhia Peninsula in New Zealand, where all of the company’s previous four rockets have also launched from. As per tradition, the rocket was given a nickname, this time being “Two Thumbs Up” – in honor of a team member who tragically died in a motorbike accident recently.

Inside the rocket is DARPA’s Radio Frequency Risk Reduction Deployment Demonstration (R3D2) satellite. Weighing in at 150 kilograms (330 pounds), it is the largest single satellite Rocket Lab has ever launched. Indeed, 150 kilograms is the upper limit of what the Electron can lift.

What exactly would it take to create our very own Swartzchild Kugelblitz?

Kugelblitz! Powering a Starship With a Black Hole

“Interstellar flight certainly ranks among the most daunting challenges ever postulated by human civilization. The distances to even the closest stars are so stupendous that constructing even a scale model of interstellar distance is impractical. For instance, if on such a model the separation of the Earth and sun is 1 inch (2.5 centimeters), the nearest star to our solar system (Proxima Centauri) would be 4.3 miles (6.9 kilometers) away!”

SpaceX has silently published the first known detailed render of its new stainless steel Starship’s design on the cover of Popular Mechanic’s April 2019 issue, showing the next-generation orbital spacecraft reentering Earth’s atmosphere in a blaze of glowing metal and plasma.

Despite the fact that the render seems to only be available in print and then only through one particular news outlet, Teslarati has acquired a partial-resolution copy of the image to share the latest official glimpse of SpaceX’s Starship with those who lack the means, access, or interest to purchase a magazine. Matters of accessibility aside, SpaceX’s updated render offers a spectacular view of Starship’s exotic metallic heat shield in action, superheating the atmosphere around it to form a veil of plasma around the spacecraft’s hull. According to CEO Elon Musk, the hottest parts of Starship’s skin will be reinforced with hexagonal tiles of steel and transpiration cooling, a largely unproven technology that SpaceX is already in the process of testing.

A source familiar with Russia’s aerospace industry recently informed state newspaper RIA Novosti that NASA has provided Russian space agency Roscosmos with an updated planning schedule for International Space Station (ISS) operations, including a preliminary target for SpaceX’s first Crew Dragon launch with astronauts aboard.

According to RIA’s source, NASA informed Roscosmos that the agency was tentatively planning for the launch of SpaceX’s Demonstration Mission 2 (DM-2) as early as July 25th, with the spacecraft departing the ISS, reentering the atmosphere, and safely returning astronauts Bob Behnken and Doug Hurley to Earth on August 5th. In a bizarre turn of events, Russian news agency TASS published a separate article barely 12 hours later, in which – once again – an anonymous space agency source told the outlet that “the [DM-2] launch of Crew Dragon is likely to be postponed to November”. For the time being, the reality likely stands somewhere in the middle.

“Space has been expanding since the Big Bang 13.7 billion years ago,” said Harold “Sunny” White, head of NASA’s Eagleworks Laboratories: Advanced Propulsion. “And we know that when you look at some of the cosmology models, there were early periods of the universe where there was explosive inflation, where two points would’ve went receding away from each other at very rapid speeds. Nature can do it. So the question is, can we do it?”

There have been hints the past few years that NASA may be on the path to discovering warp bubbles that could make the local universe accessible for human exploration. NASA scientists may be close announcing they may have broken the speed of light. According to state-of-the art theory, a warp drive could cut the travel time between stars from tens of thousands of years to weeks or months. They say they have found a way to configure the hypothetical negative energy matter so that the warping could be accomplished with a mass equivalent to the Voyager spacecraft.

“What this does is it moves the idea from the category of completely impossible to maybe plausible,” said White in a talk at NASA’s Ames Research Center in 2014. “It doesn’t say anything about feasible. And so, unfortunately, that point usually gets missed a lot.”

Humans have figured out how to send spacecraft into the deep reaches of the solar system, but it will take major advances in spaceflight before we can hop over to other star systems or traverse the Milky Way. In the meantime, though, it doesn’t hurt to think about cool ways we might one day be able to accomplish that dream.

Enter: the “halo drive,” a concept that proposes leveraging the power of black holes and other gravitationally powerful phenomena to accelerate future spacecraft to near-light speeds.

Conceived by David Kipping, an astronomer at Columbia University, the halo drive involves shooting lasers at objects such as black holes or neutron stars in order to get a speed boost when the light beam boomerangs back to its starting point.

Turns out the key to making things lighter than air is…light!

California scientists think they’ve found a way to make objects levitate using concentrated light — a theory that could even propel spacecraft farther than they’ve ever traveled before, according to a report.

Researchers at the California Institute of Technology believe that by covering the surfaces of objects with microscopic nanoscale patterns specially designed to interact with beams of light, they could be propelled without fuel — and potentially by light sources millions of miles away, according to Phys.org.
