Often linked (perhaps wrongly so) to alien-occupied flying saucers that have stopovers on Earth from the outer reaches of deep space is an equally puzzling enigma: Unidentified Anomalous Phenomenon, or UAP.

Specialized sensors are now being dispatched into the field. This gear is built to sight UAP and decipher what’s behind frequent sightings in certain hot spots of activity. For years now, the UAP mystery has blossomed, driven in-part by military pilots that have recalled their related encounters.

Congressional hearings, specially set up military organizations, even NASA itself – all have been engaged in their own close-encounters with UAP. So far, a consistent cry is “more data.”

The early science look at NASA’s OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification and Security – Regolith Explorer) has begun. Initial studies of the 4.5-billion-year-old asteroid Bennu sample collected show evidence of high-carbon content and water, which together could indicate the building blocks of life on Earth may be found in the rock. Still to come, opening up the large canister that holds the majority of the asteroid collectibles.

NASA’s Perseverance Mars rover at Jezero Crater has found features resembling reef-like structures.
Mars Guy reports that, in the very place it might be reasonable to expect, Perseverance discovered circular rock structures resembling ones formed by microbial communities in some lakes on Earth. “This exciting possibility called for a closer look.”

NASA’s Curiosity Mars rover at Gale Crater has just started Sol 3973 duties.
“Winter is almost half over in Gale, but this rover doesn’t hibernate,” reports Natalie Moore, mission operations specialist at Malin Space Science Systems, based in San Diego, California.
The last time the rover stopped for more than a few sols was at the Ubajara drill site back in early May, almost a kilometer and 150 sols ago.

“Now, five months later, we’re approaching our next drill site in this area of alternating banded layers dispersed across lithified sand,” Moore added. “The scientist jury is still out on which block is their favorite, but the operations team is already preparing to begin a two-to-three week drill campaign in the near future. With solar conjunction fast approaching, it’ll be interesting to see how much of a drill campaign we can fit between now and November 11th.”

Two-sol plan
For the recently scripted two-sol (Sols 3968-3969) unrestricted plan, Moore said there’s a remote science block containing two Navcam activities to measure the atmospheric opacity and search for dust devils, noting “we’ve seen some large ones recently!”
Mastcam will follow up with a mono, Mastcam Right-only mosaic of the upper Gediz Vallis ridge that Curiosity has been driving parallel to since a crater cluster campaign.
The robot’s Chemistry and Camera (ChemCam) is to finish off the block with a 5×1 Laser Induced Breakdown Spectroscopy (LIBS) raster on a nodular bedrock target named “Black Giant,” with Mastcam Right scheduled to document the effort afterwards.

Filter wheel stalled
On sol 3953 (September 20th, 2023) the Mastcam-34mm (Mastcam Left) filter wheel stalled between filters L0 (clear) and L1 (green) while running a multispectral atmospheric opacity (tau) imaging sequence, explains Moore.
“Since then, the Mastcam team has been sending a series of diagnostic commands with varying motor drive parameters, in an effort to characterize the problem and get the filter wheel back to the L0 position where it is most often used,” Moore said. “To date, some progress has been made, and the team is hopeful that the L0 position will be reached soon.”
Analysis will then continue to determine if the filter wheel can be safely returned to normal service. “Remember, this rover has been outside Earth’s protection since late 2011! This isn’t the first time our engineering team fixed something remotely and it won’t be the last,” Moore reported.

Evening integration
After another Mastcam Left diagnostic activity was set to complete, the first arm backbone was slated to kick off and includes two contact science targets: “Helen Lake” (a less dusty dark-toned layer) and “Marion Peak” (a slightly dustier dark-toned layer).
The rover’s Mars Hand Lens Imager (MAHLI) was scheduled to take a full-suite of images on Helen Lake from 25, 5, and 2centimeters away and another mini-suite of images on Marion Peak from 25 centimeters and 5 centimeters away.
After the imaging, the robot’s arm turret was to spin to the Alpha Particle X-Ray Spectrometer (APXS) frame for their evening integrations on the two targets.

Nap the night away
The first orbiter to pass over Curiosity will be the [European Space Agency] Trace Gas Orbiter, which should send data packages back to Earth.
“We mostly nap the night away, and on the second sol we’ll wake up with another remote sensing block starting again with a Navcam dust devil movie. Mastcam will follow up this time with some near-field mosaics of sand troughs between blocks, and ChemCam will shoot their second LIBS target named “Bridgeport” on a smoother piece of bedrock,” Moore explained.
With Curiosity’s arm activities done, rover operators will be ready to drive and potentially end up near the rover’s next drill site.

Visual Capitalist – an online publisher focused on topics and markets such as technology, energy and the global economy – has issued an informative look at Moon exploration.
Preyash Shah of Visual Capitalist has provided an interesting overview of attempted and successful Moon landings:
Since before Ancient Greece and the first Chinese Dynasties, people have sought to understand and learn more about the Moon.
Curiosity and centuries of study culminated in the first Moon landing in the 1960s. But there have been many other attempted Moon landings, both before and after.
A chart by Shah illustrates all the Moon landings using NASA data since 1966 when Soviet lander Luna 9 touched down.

Race to the Moon
The 1960s and 1970s marked an era of intense competition between the U.S. and the Soviet Union as they raced to conquer the Moon.
During the Cold War, space became a priority as each side sought to prove the superiority of its technology, its military firepower, and its political-economic system.
In 1961, President John F. Kennedy set a national goal to have a crewed lunar landing and return to Earth.
After several failed attempts from both sides, on July 20, 1969, the Apollo 11 mission was successful and astronauts Neil Armstrong and Buzz Aldrin became the first humans to set foot on the Moon.

Fervor waned
After the Apollo missions, the fervor of lunar exploration waned. From 1976 to 2013, no Moon landing attempts occurred due to budget constraints, shifting priorities, and advances in robotic missions.
However, a new chapter in space exploration has unfolded in recent years, with emerging players entering the cosmic arena. With its Chang’e missions, China has made significant strides, landing rovers on the Moon and exploring the far side of the Moon.
India, too, has asserted its presence with the Chandrayaan missions. In 2023, the country became the 4th nation to reach the Moon as an unmanned spacecraft landed near the lunar south pole, advancing the country’s space ambitions to learn more about the lunar ice, potentially one of the Moon’s most valuable resources.

Exploring Lunar Water
Since the 1960s, even before the historic Apollo landing, scientists had theorized the potential existence of water on the Moon.
In 2008, Brown University researchers employed advanced technology to reexamine lunar samples, discovering hydrogen within beads of volcanic glass. And in 2009, a NASA instrument aboard the India’s Chandrayaan-1 probe confirmed the presence of water on the moon’s surface.

Water is deemed crucial for future space exploration. Beyond serving as a potential source of drinking water for future Moon explorations, ice deposits could play a pivotal role in cooling equipment. Lunar ice could also be broken down to produce hydrogen for fuel and oxygen for breathing, essential for supporting extended space missions.
With a reinvigorated interest in exploring the Moon, manned Moon landings are on the horizon once again. In April 2023, NASA conducted tests for the launch of Artemis I, the first American spacecraft to aim for the Moon since 1972. The agency aims to send astronauts to the Moon around 2025 and build a base camp on the lunar surface.

Scheduled for launch next year, the bus-sized CSST houses a two-meter (6.6 foot) diameter primary mirror. This ultraviolet-optical space telescope is to co-orbit with the country’s Tiangong orbital outpost. It has a nominal mission lifetime of 10 years, but the observatory’s space duties could be extended.

That failed Russian Luna-25 robotic lunar lander was likely taken out by out-of-whack accelerometer hardware, part of the BIUS-L component that provides angular velocity measurements.
Russia’s rekindling of its lunar program following the former Soviet Union’s pioneering Moon exploration initiatives that ended in 1976 will move forward, according to Roscosmos chief, Yuri Borisov.
During preparations for descent to the surface, Russia’s Luna-25 Moon lander experienced an anomaly that caused it to impact into the southwest rim of Pontécoulant G crater on Aug. 19, 2023, at 7:58 a.m. EDT (11:58 a.m. UTC).

In a look into the Luna-25 mishap, the craft’s propulsion system on August 19 operated for 127 seconds instead of a planned 84 seconds – an incorrect propulsive maneuver that sent the lander onto a crashing finish on the Moon.
On August 19 that impulse was meant to form the probe’s pre-landing elliptical orbit. However, communication with the automatic station was interrupted. A subsequent search for Luna-25 did not produce results.

Abnormal functioning
According to a Roscosmos posting, the culprit was the abnormal functioning of the on-board control complex, “associated with the failure to turn on the accelerometer unit in the BIUS-L device (angular velocity measurement unit) due to the possible entry into one data array of commands with different priorities for their execution by the device. In this case, the distribution of commands in data arrays is random (probabilistic) in nature.”

The on-board control complex received zero signals from the accelerometers of the BIUS-L device. Reportedly, this hardware had not been previously flown under actual space conditions.
“This did not allow, when issuing a corrective pulse, to record the moment the required speed was reached and to timely turn off the spacecraft propulsion system, as a result of which its shutdown occurred according to a temporary setting,” the Roscosmos Telegram communiqué adds.

Moving forward
Recommendations to avoid a similar issue on subsequent lunar missions have been formulated.
At the now-underway International Astronautical Congress meeting in Baku, Yuri Borisov also reported that the interdepartmental commission to determine the reasons for the abnormal functioning of the Luna-25 automatic station had completed its work and that a report was being prepared to the Government of the Russian Federation.

“No one is going to fold their arms, and we are determined to continue the lunar program. Moreover, we are considering the possibility of shifting the Luna-26 and Luna-27 missions to the left in order to get the results we need as quickly as possible,” Borisov said.

Consider it sound advice.
The use of tiny microphones on NASA’s Mars Perseverance has proven big time beneficial to both engineers and scientists. They can identify wind gusts even hear the staccato popping sounds made by instrument-generated laser pulses.
Similarly, the swirling blades of the Ingenuity Mars helicopter have been picked up, as has the pumping rhythm of an oxygen-making experiment.
Hear, hear! Flights of the Ingenuity Mars helicopter have been picked up by the Perseverance rover, offering both valuable engineering and scientific data.

Thanks to the Perseverance machinery rolling about within Jezero Crater, it’s time to turn up the volume on microphones for extra-planetary exploration.
