Upcoming space mission to test Purdue-developed drag sail pulling rocket back to Earth

Called “Spinnaker3,” this drag sail isn’t the first to be launched into space. But it is among the first to be large enough for deorbiting the upper stage of a launch vehicle. The Firefly Alpha launch will target an orbit altitude of about 200 miles, but the Spinnaker3 drag sail is capable of providing deorbit capability from orbit altitudes of 400 miles or greater.

WEST LAFAYETTE, Ind. — A rocket is going up into space with a drag sail. The goal? For the drag sail to bring the rocket back to Earth, preventing it from becoming like the thousands of pieces of space junk in Earth’s lower orbit.

The drag sail, developed by Purdue University engineers, will be on board a Firefly Aerospace rocket expected to launch in November from Vandenberg Air Force Base in California.

This sail and six other “Dedicated Research and Education Accelerator Mission” (DREAM) payloads are flying on Firefly Aerospace’s Alpha launch, the first flight for the launch vehicle company.

This NASA Animation Shows What It’s Really Like to Travel Close to The Speed of Light

If you’re a fan of science fiction, chances are you encountered a few franchises where humanity has spread throughout the known Universe. The ships that allow them to do this, maybe they use a warp drive, maybe they “fold space,” maybe have a faster-than-light (FTL) or “jump” drive.

It’s a cool idea, the thought of “going interstellar!” Unfortunately, the immutable laws of physics tell us that this is simply not possible.

However, the physics that govern our Universe do allow for travel that is close to the speed of light, even though getting to that speed would require a tremendous amount of energy.

NASA boffin invents ‘engine concept’ that travels at 99% the speed of light – and it could ‘break the laws of physics’

O,.o earth to Mars 12.5 minutes.

A NASA scientist has cooked up plans for a bonkers new rocket engine that can reach close to the speed of light – without using any fuel.

Travelling at such speeds, the theoretical machine could carry astronauts to Mars in less than 13 minutes, or to the Moon in just over a second.

However, the real purpose of the so-called “helical engine” would be to travel to distant stars far quicker than any existing tech, according to NASA engineer Dr David Burns.

Astronomers Mystified by Eerie Phenomenon on Mars: Ultraviolet “Nightglow” Spreads Across the Planet’s Sky Every Night

This is an image of the ultraviolet “nightglow” in the Martian atmosphere over the south pole. Green and white false colors represent the intensity of ultraviolet light, with white being the brightest. The nightglow was measured at about 70 kilometers (approximately 40 miles) altitude by the Imaging UltraViolet Spectrograph instrument on NASA’s MAVEN spacecraft. A simulated view of the Mars globe is added digitally for context, and the faint white area in the center of the image is the polar ice cap. The image shows an unexpectedly bright glowing spiral in Mars’ nightside atmosphere. The cause of the spiral pattern is unknown. Credit: NASA/MAVEN/Goddard Space Flight Center/CU/LASP

Every night on Mars, when the sun sets and temperatures fall to minus 80 degrees Fahrenheit and below, an eerie phenomenon spreads across much of the planet’s sky: a soft glow created by chemical reactions occurring tens of miles above the surface.

An astronaut standing on Mars couldn’t see this “nightglow”—it shows up only as ultraviolet light. But it may one day help scientists to better predict the churn of Mars’ surprisingly complex atmosphere.

Why is it important to consider human rights in space?

From most people’s perspectives, space law is a fairly niche field. Even more niche are particular sub-fields of space law, such as space human rights law. Despite being so niche, though, one can argue that space human rights law is extremely important. It defines how humans treat each other as they expand into new off-planet environments. It thus fundamentally shapes how humanity engages with space. To learn more about the intersection of human rights and space exploration, we spoke to Jonathan Lim, a solicitor at the law firm WiseLaw. He is also the founder of Jus Ad Astra, a project at WiseLaw that develops legal principles pertaining to space exploration.

What role do human rights play in space exploration?

Human rights are inalienable and universal values that recognize the inherent value of each person. They are based upon the common values of dignity, equality, and respect shared across all cultures, religions, and philosophies. The intersection between human rights and outer space can be viewed through two perspectives.

Surviving bacteria in space

Research has shown that bacteria are surprisingly resistant organisms, both on Earth and in space, especially when they form ‘biofilms’. The relative isolation of astronaut crews poses a particular challenge to the field of biohazard management and this will only increase for future missions to the Moon and Mars. This article, based on a presentation at the Asgardia Space Science & Investment Congress (ASIC) in Darmstadt, Germany, in October, explains some of the issues and describes the state of play in this research.

Gregg Maryniak – interviewed by Corrinne Graham, for Space Renaissance Academy Mentorship Programme

Corrinne Graham (Economic financial analyst, Space Renaissance USA) interviewed Gregg Maryniak, about his history, motivation and aims to inspire young generations to find their way to the outer space. Gregg is the co-founder, together with Peter Diamandis, of the X-Prize Foundation. The X-Prize is recognized, by the space community, as the initiative that triggered the New Space revolution, by demonstrating that the low cost access to space was feasible and mature. He was the Executive Director of the Space Studies Institute, founded by Gerard O’Neill in Chicago, US. He’s on the Board of Directors of the Singularity University and keeps on restlessly working to inspire and motivate youngs, students and public opinion at large, explaining why human expansion into space is needed and very urgent, in order not to miss our “launch window”. During the conversation, we acknowledged that we agree on many points, all of them primary relevant to the survival and continued progress of civilization. Namely the common appreciation for the O’Neill’s model, that gives priority and preference to artificial rotating structures – the “space colonies” – since they assure 1G artificial gravity. Also, we are 100% in tune about the extreme urgency of kicking-off civilian expansion into outer space, and the subsequent need to make people to understand it. The big risk – said Gregg — is to miss our launch window, the period in which social and economic conditions are favorable to begin really moving into space. When I asked him whether he thinks that humanity is doing everything that is to be done, and if we are in time, on our evolutionary road to space, his answer was a clear “NO”. So we understood that we also agree on the most urgent technology advances to be raised as priority: the enabling technologies, necessary to bring untrained civilians to travel, live and work in space. Namely low acceleration vehicles, protection against cosmic radiations, artificial gravity, green environments and artificial ecosystems in space habitats. Gregg is a great achievement indeed, in our SR Academy Mentorship Programme. After this first meeting, we’ll try to hold other ones, properly announced on social networks, with the target to bring the above discussion to large public opinion.
