SpaceX announced a new capability for the Dragon spacecraft on Sept. 27 in the unlikely event of a parachute failure. Dragon now has built-in redundancy to propulsively land using its SuperDraco thrusters, saving the vehicle and potential crew from a rough landing or imminent danger.

SpaceX introduced the concept of a propulsive landing Dragon over ten years ago. When SpaceX revealed Dragon 2, it was marketed as capable of propulsively landing anywhere on Earth and was initially designed to land exclusively with the SuperDracos. However, SpaceX ultimately pursued the use of parachutes as the main form of recovery for Dragon 2 missions.

Much has had to change with Dragon 2 since May 30, 2014, to make it the reliable crewed spacecraft we know it as today. Now, SpaceX has decided to bring back one of the main capabilities that was believed to have been left behind in development.

Scientists have used gene-editing techniques to boost the repair of nerve cells damaged in multiple sclerosis, a study shows. The innovative method, which was tested in mice, supports the development of cells that can repair the protective myelin coating around nerves, restoring their ability to conduct messages to the brain.

The findings, now published in Nature Communications, offer a potential route for future treatments to stop disability progression, experts say.

Our bodies have the ability to repair myelin, but in multiple sclerosis (MS), and as we age, this becomes less effective. There are currently no treatments to boost this process.

Company Awarded AFRL Contract to Investigate the Delivery of Five-to-Ten-Ton Capacity Containers Anywhere in the World in 90 Minutes

LOUISVILLE, Colo. – October 3, 2024 – Sierra Space, a leading commercial space company and defense-tech prime that is Building a Platform in Space to Benefit Life on Earth® and protect economic freedom in the Orbital Age®, announced today that it has been awarded a competitive, firm-fixed-price contract for the Rocket Experimentation for Global Agile Logistics (REGAL) program by Air Force Research Laboratory (AFRL). This new contract aims to revolutionize logistics and materiel returns from space, placing Sierra Space at the forefront of defense and space logistics innovation.

Earlier this year, the company unveiled its Sierra Space Ghost decelerator – a revolutionary logistics spacecraft designed for rapid payload return from Earth orbit – and shared the results of successful beta flight testing. The REGAL contract will support efforts to conceptually design and scale this new breakthrough technology, with the goal of landing critical supplies anywhere on the planet within 90 minutes.

Radian Aerospace has $31 million of funding to develop a single stage to orbit spaceplane. It will use a 3,000 meter long sled to get it up to launch speed. It will deliver 2.27 tons to anywhere on Earth in under one hour. It can land on a regular runway.

The Spaceplane will be about as long as a Boeing 787 and as wide as a 737.

The spaceplane is designed to be fully reusable for up to 100 missions. They plan a 48-hour turnaround time between flights and a 90-minute on-demand launch capability, significantly reducing costs and increasing mission flexibility.

NASAs Europa Clipper, the largest spacecraft designed for a planetary mission, was recently moved to the SpaceX hangar at Launch Complex 39A in anticipation of its launch.

The spacecraft, encapsulated within payload fairings for protection, is set to be mounted on a SpaceX Falcon Heavy rocket.

Part of the delight in reading science fiction is seeing how real science can be extrapolated to envision future technologies, whether here on Earth or in extraterrestrial environments. Starships are a ubiquitous presence in science fiction and a prototypical example of technology that can stimulate the imagination of future scientists and engineers. As a materials scientist, I am particularly intrigued by the role of various materials (metals, ceramics, glasses, polymers, nanomaterials, etc.) in building the starships of tomorrow.

The purpose of this science-meets-science fiction initiative, which we are calling Project Starship, is to deepen the connection between the scientific and science fiction communities, helping to stimulate new interest in both fields. To kick off this series of articles, Grimdark Magazine reached out to three leading voices in dark science fiction to explore the materials required for designing the starships from within their fictional universes. First up is Graham McNeill, a British novelist best known for his Warhammer 40k novels, including Nightbringer. Next is Richard Swan, critically acclaimed author of the dark science fiction trilogy, The Art of War. Finally, Essa Hansen is author of the dark science fiction series, The Graven, which begins with the critically acclaimed Nophek Gloss.

NASA is developing a new Lunar Terrain Vehicle (LTV) for the Artemis missions to the Moon, enabling astronauts to explore more expansively and conduct in-depth scientific research.

The Ground Test Unit (GTU), a prototype, is being tested on Earth to evaluate different rover concepts and ensure reliability and functionality before deployment. This initiative includes collaborations with three vendors and aims to bolster technological advancements for future lunar and Martian explorations.

As NASA advances the Artemis II mission, significant strides are being made with the mobile launcher at Kennedy Space Center.

Recently moved back to the Vehicle Assembly Building after undergoing extensive testing and upgrades, the launcher is central to launching the next Moon rocket. Alongside, the crawler-transporter marked a historical milestone, reaching over 2,500 miles since its inception, reinforcing its title as the heaviest self-powered vehicle by Guinness World Records.

When is an empty tube not an empty tube? When it’s a ramjet that uses rotating detonation technology to propel aircraft at hypersonic speeds. A case in point is Venus Aerospace’s new Venus Detonation Ramjet 2000 lb Thrust Engine (VDR2).

One of the biggest hurdles that need to be cleared in making hypersonic flight practical is building engines that are capable of sustained thrust.

Currently, hypersonic systems are mainly based on glide bodies that are boosted to high speed and altitude by rockets and then accelerate to over Mach 5 by gliding back to lower altitudes. However, if you want to build airliners that can fly from San Francisco to Tokyo in one hour, you need something more like a jet engine.
