NASA’s Jet Propulsion Laboratory (JPL) announced hundreds of layoffs, calling the move “painful but necessary.” The news came via a workforce statement and memo to JPL employees. JPL has been on the forefront of space exploration for decades. It was a camera, engineered by the space agency, on Voyager 1 that was able to capture the pale

NASA's Jet Propulsion Laboratory has laid-off an additional 325 workers after an earlier round of 500 job cuts earlier in the year, largely because of budgetary constraints.

(EMAILWIRE.COM, October 31, 2024 ) The UAV-Drone Propulsion Systems Market is forecasted to grow from USD 6,994 million in 2024 to USD 11,098 million by 2029, at a CAGR of 10.9%. As UAV applications expand across sectors like defense, government, and commercial use, demand is accelerating for more...

The Jet Propulsion Laboratory, NASA's research center responsible for robotic space missions, will lay off more workers before the year ends due to budget constraints. JPL Director Laurie Leshin has announced in a memo addressed to employees that the reduction will affect 325 people, or about five percent of its whole workforce. Leshin explained that the lab took various measures to meet its budget allocation for the 2025 fiscal year and to minimize the adverse effects of a limited budget on its workers. In the end, though, JPL "reached the difficult decision" to make "one further workforce reduction."

The lab already cut 530 employees and cut over 100 contractors from its roster earlier this year because of uncertainty over the final budget that the Congress will give NASA for 2024. It also froze hiring in response to the dilemma. The main reason why the lab had to implement those measures was because the Mars Sample Return Program was allocated a much smaller budget than it needed. NASA had requested $950 million for the mission, but only $300 million was allocated for it. 

NASA's original plan was to bring home the samples collected by the mission in 2040. But its budget ballooned from $7 billion to $11 billion, and as The Washington Post notes, the government found the return date "unacceptable." For the 2025 fiscal year, NASA only requested $200 million for the project that could go through significant changes. The agency is now looking for ways to alter the mission and is even considering proposals from private companies. 

Leshin said that the layoffs will affect all areas of the lab, including its technical, business and support divisions. "[W]e had to tighten our belts across the board, and you will see that reflected in the layoff impacts," she said. JPL's director also said that the US presidential election results have nothing to do with the reduction that the "action would be happening regardless" of its outcome. 

Using nuclear propulsion technologies to support a human mission to Mars in 2039 will require NASA to pursue an aggressive and urgent technology development program, says a new report from the National Academies of Sciences, Engineering, and Medicine.

A propulsion apparatus for an endoscope includes a propulsion assembly for mounting on a tip device of the endoscope, for propulsion in a body cavity. First and second wire devices are disposed to extend from the tip device in a proximal direction, having a coil winding, for rotating to drive the propulsion assembly. First and second motors are connected with proximal ends of respectively the first and second wire devices, for rotating the first and second wire devices. A timer is actuated if a speed difference between rotational speeds of the first and second motors becomes equal to or more than a reference speed value, for measuring an elapsed time. A break detector detects breakage of the first wire device if the elapsed time becomes equal to or longer than a predetermined time. A controller controls the first and second motors in response to an output of the break detector.

A propulsion device using fluid flow quickly discharges the vortex flow generated on an upper surface of the propulsion device to the outside to improve the propulsion and thrust of transportation means provided with the propulsion device. For this purpose, the propulsion device includes a fluid storage unit in which a downwardly curved fluid storage surface is formed between a first inlet line and a first outlet line such that a fluid storage space is formed on the fluid storage surface. A fluid flow unit in which a downwardly curved fluid flow surface is formed between a second inlet line and a second outlet line which are outwardly and backwardly inclined such that a fluid flow space is formed on the fluid flow surface. The-fluid flow surface adjacent to the second outlet line becomes gradually flattened as it extends outwardly.

Self-propelling, programmable nanoscopic motors capable of harvesting energy from absorbed photons and undergoing subsequent photoeletrochemical (PEC) reactions are provided. A nanomotor can have a three-dimensional Janus configuration and can sense the direction of a light source. By controlling the zeta potential of different parts of the nanomotor with chemical modifications, the nanomotor can be programmed to show either positive phototaxis or negative phototaxis.

A gas turbine engine system and method of operating gas turbine engines are provided. The gas turbine engine assembly includes a gas turbine engine includes a power shaft configured to rotate about an axis of rotation. The gas turbine engine assembly also includes a first fan and a second fan coupled to the power shaft coaxially with the gas turbine engine. The gas turbine engine assembly also includes a first fan duct configured to direct a first stream of air to the first fan. The gas turbine engine assembly also includes a second fan duct configured to direct a second stream of air to the second fan. The gas turbine engine assembly also includes an exhaust duct configured to direct a stream of exhaust gases of the gas turbine engine in a direction of the axis of rotation.

Two Seattle-area space ventures — Tethers Unlimited and Rocket Propulsion Systems — are among 124 businesses receiving $750,000 Phase II grants from NASA's Small Business Innovation Research program. The two-year grants, announced today, support the further development of technologies that can benefit future space missions as well as life on Earth. All of the recipients, hailing from 31 states in all, received $125,000 Phase I grants during earlier rounds of funding. "We are encouraged by the ingenuity and creativity we’ve seen from these companies in their Phase I work," Jenn Gustetic, NASA's SBIR program executive said in a news release.… Read More
