James Webb Space Telescope getting closer to launch

The multi-billion dollar successor of the Hubble telescope, NASA’s James Webb Space Telescope, has completed a couple of crucial tests and is closer to its shipment to French Guiana for launch, NASA said. “With the completion of its latest series of milestone tests, NASA’s James Webb Space Telescope has now survived all of the harsh conditions associated with a rocket launch to space,” the U.S. space agency said.

The James Webb Space Telescope is the world’s largest, most powerful, and complex space science telescope ever built; the program – named after the second NASA Administrator in the sixties – is led by NASA, along with its partners ESA (European Space Agency) and the Canadian Space Agency. “Webb is NASA’s next great space science observatory, which will help in solving the mysteries of our solar system, looking beyond to distant worlds around other stars, and probing the mystifying structures and origins of our universe,” NASA said.

U.S. Transportation Command to study use of SpaceX rockets to move cargo around the world

The U.S. military command that oversees logistics operations has signed an agreement with SpaceX and XArc to study the use of space launch vehicles to transport supplies in an emergency. Army Gen. Stephen Lyons, commander of U.S. Transportation Command, announced the agreement Oct. 7 at a National Defense Transportation Association virtual conference. “Think about moving the equivalent of a C-17 payload anywhere on the globe in less than an hour,” Lyons said. The C-17 is a very large military cargo plane capable of transporting a 70-ton main battle tank.

Transportation Command has signed a cooperative research and development agreement, known as CRADA, with SpaceX and Exploration Architecture Corporation (XArc) to study concepts for rapid transportation through space. “There is a lot of potential here,” said Lyons He noted that one of the challenges of military logistics is the “tyranny of distance and time, and global access.” Space transportation is weight- and volume-constrained compared to airlift, and has limited options for launching and recovery operations. “As industry advances to overcome these challenges and decrease costs, a space transportation capability to put a crucial cargo quickly on target at considerable distances makes it an attractive alternative,” said U.S. TRANSCOM Deputy Commander Vice Adm. Dee Mewbourne.

‘Self-eating rocket’ tech snags funding from UK government

The U.K. government aims to spur the development of rockets that gobble themselves up on the way to orbit. The Ministry of Defence’s Defence & Security Accelerator (DASA) has pledged £90,000 — about $117,000 USD at current exchange rates — for the continued development of the “autophage” rocket engine, which is being built by researchers at the University of Glasgow in Scotland. The tech is a great fit for small rockets “because scaling down a rocket reduces the mass of the propellant more than it reduces the mass of all the other components, including the tanks that hold the propellant itself,” Patrick Harkness, of the University of Glasgow’s James Watt School of Engineering, said in a statement. “The autophage concept is simple: burn the tanks as well,” Harkess said. “That saves the excess mass, and it means that we can miniaturize the vehicle without hitting this wall.”

The Glasgow team has already test-fired a version of the autophage engine that burns all-solid propellant. The DASA money will help fund research into the use of a more energy-rich hybrid propellant, team members said. “The body of a hybrid autophage rocket will be a tube of solid fuel, containing a liquid oxidizer,” Harkess said. “The entire assembly will be consumed, from the bottom up, by an engine which will vaporize the fuel tube, add the oxidizer and burn the mixture to create thrust. The engine will have consumed the entire body of the rocket by the time the assembly reaches orbit, and only the payload will be left. It is a much more mass-efficient process.” The hybrid engine will be test-fired next year, at Kingston University in London, if all goes according to plan.
