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.

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.

SILVER SPRING, Md. — Blue Origin has studied repurposing upper stages of its future New Glenn launch vehicle to serve as habitats or for other applications as part of a series of NASA-funded commercialization studies.

Brett Alexander, vice president of government sales and strategy at Blue Origin, said the company looked at ways it could make use of the second stage of New Glenn rather than simply deorbiting the stage at the end of each launch, but emphasized the company currently had no firm plans to reuse those stages at this time.

That study was part of a series of study contracts awarded by NASA last August to study future concepts to support commercial human spaceflight in low Earth orbit. “We focused there on the reuse of the second stage of New Glenn and what we might be able to do with that volume and capacity once we’re on orbit,” he said during a panel discussion about low Earth orbit commercialization at the American Astronautical Society’s Goddard Memorial Symposium here March 20.

Astronomers found a pulsar hurtling through space at nearly 2.5 million miles an hour — so fast it could travel the distance between Earth and the Moon in just 6 minutes. The discovery was made using NASA’s Fermi Gamma-ray Space Telescope and the National Science Foundation’s Karl G. Jansky Very Large Array (VLA).

“Thanks to its narrow dart-like tail and a fortuitous viewing angle, we can trace this pulsar straight back to its birthplace,” said Frank Schinzel, a scientist at the National Radio Astronomy Observatory (NRAO) in Socorro, New Mexico. “Further study of this object will help us better understand how these explosions are able to ‘kick’ neutron stars to such high speed.” Schinzel, together with his colleagues Matthew Kerr at the U.S. Naval Research Laboratory in Washington, and NRAO scientists Dale Frail, Urvashi Rau and Sanjay Bhatnagar presented the discovery at the High Energy Astrophysics Division meeting of the American Astronomical Society in Monterey, California. A paper describing the team’s results has been submitted for publication in a future edition of The Astrophysical Journal Letters.

Researchers at Caltech have designed a way to levitate and propel objects using only light, by creating specific nanoscale patterning on the objects’ surfaces.

Though still theoretical, the work is a step toward developing a spacecraft that could reach the nearest planet outside of our solar system in 20 years, powered and accelerated only by light.

A paper describing the research appears online in the March 18 issue of the journal Nature Photonics. The research was done in the laboratory of Harry Atwater, Howard Hughes Professor of Applied Physics and Materials Science in Caltech’s Division of Engineering and Applied Science.

A new report by Swiss investment bank UBS predicts that soon high speed travel through the near reaches of space will come to compete with long-haul airline flights.

UBS analysts estimate that space tourism alone will become a $3 billion market by 2030, while the space industry as a whole will double in worth from $400 billion today to $805 billion over the same period. And once we can spend a week of vacation in space, they ask, why not use the technology for Earth-bound long-distance travel?

“Space tourism could be the stepping stone for the development of long-haul travel on earth serviced by space,” wrote UBS analysts Jarrod Castle and Myles Walton in the report, as quoted by CNBC.
