Pratt & Whitney Projects Peak Number of Grounded Aircraft to be Lower Than Previously Thought

FlightGlobal reports that Pratt & Whitney “expects the peak number of aircraft grounded as a result of manufacturing problems with geared turbofan engines will be lower than previously anticipated as the propulsion specialist continues to work through the issue.” In September, the engine maker “expanded a previously announced requirement for ‘accelerated inspections’ of the PW1100G engines that power Airbus A320neo-family jets due to a manufacturing problem.” Caused by contamination “of the powder metal material used to make high-pressure turbine and compressor disks, the issue will see thousands of aircraft taken out of service over the next two years for checks.” But “speaking to analysts on a full-year earnings call on 23 January, Christopher Calio, chief operating officer of P&W parent RTX, said although the recovery process was in its early stages, progress is being made.”

NASA’s Ingenuity Helicopter Comes Back Online on Mars After Communications Glitch

SPACE reports that Ingenuity has officially “regained communication with ground control.” According to a January 20 NASA post, Perseverance “had conducted long-duration listening sessions to help pinpoint Ingenuity’s signal.” Everything “seemed fine during the probe’s 72nd hop on Mars’ red surface, as it successfully climbed to an expected maximum altitude of 40 feet (12 meters) and communicated its ascension status with Perseverance.” But, during descent, NASA said that “communications between the helicopter and rover terminated early, prior to touchdown.”

X-59 Promises to Open a New Era of Supersonic Travel

The Times (UK) reports the X-59, built by Skunk Works, “promises to open a new era of supersonic travel.” The X-59 “has been designed to fly faster than the speed of sound without generating the thunderous, window-rattling sonic boom that has, until now, accompanied all supersonic flight. Instead, it should produce what NASA describe as a ‘gentle sonic thump’ – about as loud as a car door being slammed several metres away. The aim is to persuade regulators, including in Britain, to amend rules that have banned faster-than-sound commercial flights over land since the 1970s because of the noise nuisance.” Later this year, according to The Times, the “X-59 will pass over densely populated areas of the US. Residents will be asked what they think about the thump and the findings will guide future legislation.”

Japan Becomes Fifth Country to Land a Spacecraft on the Moon

ABC News reports “Japan became the fifth country in history to reach the moon” when one of its uncrewed spacecrafts “successfully made a soft landing on the lunar surface early Saturday.”  Japan’s Smart Lander for Investigating Moon (SLIM) touched down within the Shioli crater at 10:20 a.m. Eastern, Jan. 19 (12:20 a.m. JST, Jan. 20). JAXA confirmed the successful landing approximately two hours later. Japanese space officials “said the craft’s solar panel had failed to generate power, which could shorten its activity on the moon.”  Japan joins the US, China, the Soviet Union, and India as all having made it to the lunar surface.

Astronauts Arrive at ISS

Reuters reported a four-man crew “arrived at the International Space Station (ISS) early on Saturday for a two-week stay in the latest such mission arranged entirely at commercial expense by Texas-based startup company Axiom Space.” Their arrival “came about 37 hours after the Axiom quartet’s Thursday evening liftoff in a rocketship from NASA’s Kennedy Space Center in Cape Canaveral, Florida.”

B-21 Raider Flies Test Sortie from Edwards Air Force Base

Aviation Week reports that a “Northrop Grumman B-21 Raider flew a test sortie from Edwards AFB, California, on Jan. 17, notching the second acknowledged flight of the second-generation stealth bomber.” Defense News reports US Air Force spokeswoman Ann Stefanek said, “Flight testing is a critical step in the test campaign managed by the Air Force Test Center and 412th Test Wing’s B-21 combined test force to provide survivable, long-range, penetrating strike capabilities to deter aggression and strategic attacks against the United States, allies and partners.” According to Defense News, “Northrop Grumman has built or is in the process of building at least six test B-21s, including this first bomber. The B-21 program is now in the engineering and manufacturing development phase, and the test aircraft are production-representative platforms, meaning they are being built on the same line with the same tools, technicians and processes as production bombers. Ellsworth Air Force Base in South Dakota is to be the first base to receive a Raider, scheduled for delivery in the mid-2020s.”

Astrobotic’s Peregrine Moon Lander Disintegrates in Earth’s Atmosphere

The New York Times reports that a spacecraft that “was headed to the surface of the moon has ended up back at Earth instead, burning up in the planet’s atmosphere on Thursday afternoon.” Astrobotic Technology of Pittsburgh “announced in a post on the social network X that it lost communication with its Peregrine moon lander at 3:50 p.m. Eastern time, which served as an indication that it entered the Earth’s atmosphere over the South Pacific at around 4:04 p.m.” It was a sad end to a trip that “lasted 10 days and covered more than half a million miles, with the craft traveling past the orbit of the moon before swinging back toward Earth.” But the spacecraft “never got close to its landing destination on the near side of the moon.” The main payloads “on the spacecraft were from NASA, part of an effort to put experiments on the moon at a lower cost by using commercial companies.” Astrobotic’s launch “was the first in the program, known as Commercial Lunar Payload Services, or CLPS.”

AIAA Statement on the Axiom Space AX-3 Launch

FOR IMMEDIATE RELEASE

January 18, 2024 – Reston, Va. –  The American Institute of Aeronautics and Astronautics (AIAA) CEO Dan Dumbacher made the following statement:

“On behalf of the 30,000 professional and student members of AIAA, we congratulate the entire Axiom Space team on its successful AX-3 launch onboard a SpaceX Falcon 9 rocket. We applaud this private mission to the International Space Station (ISS), showing how NASA and private industry are working together to extend the human neighborhood into low Earth orbit.

It is exciting to anticipate the AX-3 crew’s busy schedule onboard the ISS orbiting laboratory, conducting more than 30 scientific investigations into human health and well-being, radiation exposure, genetic expression, and Earth observations. This meaningful research in space is expanding our scientific knowledge as we witness the space economy growing. These explorers and innovators are working to improve life on Earth and accelerate our off-world future. We look forward to following their progress.

We recognize the countless aerospace industry professionals involved in making this mission a success. We salute AIAA Corporate Member Axiom Space, as they collaborate with NASA and SpaceX. They are shaping the future of aerospace.”
