Some time ago, while visiting the Grand Canyon in Arizona, a photographer captured several short video clips of the landscape. In one of those clips, an unusual anomaly was discovered.
The original footage is only 1.9 seconds long, but within that moment, something remarkable was caught on camera. An unidentified aerial phenomenon (UAP) flashed across the frame, visible for less than a second, only noticeable when the video was paused and analyzed frame by frame.
The object was moving at an astonishing speed, covering an estimated two to three miles in under a second, far beyond the capabilities of any conventional aircraft, drone, or helicopter.
This isn’t the first time such anomalous flying objects have been observed. Their characteristics defy comparison with known aerial technology.
Some skeptics have proposed that the object might have been a rock thrown into the canyon from behind the camera. However, that explanation seems unlikely. Most people can only throw objects at speeds of 10 to 20 meters per second (approximately 22 to 45 mph). The velocity of this object far exceeded that range, and its near-invisibility in the unedited video suggests it was moving much faster.

Sols 4549-4552: Keeping Busy Over the Long Weekend
NASA’s Mars rover Curiosity acquired this image using its Left Navigation Camera on May 23, 2025 — Sol 4548, or Martian day 4,548 of the Mars Science Laboratory mission — at 07:17:19 UTC. NASA/JPL-Caltech Written by Conor Hayes, Graduate Student at York University
Earth planning date: Friday, May 23, 2025
In Wednesday’s mission update, Alex mentioned that this past Monday’s plan included a “marathon” drive of 45 meters (148 feet). Today, we found ourselves almost 70 meters (230 feet) from where we were on Wednesday. This was our longest drive since the truly enormous 97-meter (318-foot) drive back on sol 3744.
Today’s plan looks a little different from our usual weekend plans. Because of the U.S. Memorial Day holiday on Monday, the team will next assemble on Tuesday, so an extra sol had to be appended to the weekend plan. This extra sol is mostly being used for our next drive (about 42 meters or 138 feet), which means that all of the science that we have planned today can be done “targeted,” i.e., we know exactly where the rover is. As a result, we can use the instruments on our arm to poke at specific targets close to the rover, rather than filling our science time exclusively with remote sensing activities of farther-away features.
The rover’s power needs are continuing to dominate planning. Although we passed aphelion (the farthest distance Mars is from the Sun) a bit over a month ago and so are now getting closer to the Sun, we’re just about a week away from winter solstice in the southern hemisphere. This is the time of year when Gale Crater receives the least amount of light from the Sun, leading to particularly cold temperatures even during the day, and thus more power being needed to keep the rover and its instruments warm. On the bright side, being at the coldest time of the year means that we have only warmer sols to look forward to!
Given the need to keep strictly to our allotted power budget, everyone did a phenomenal job finding optimizations to ensure that we could fit as much science into this plan as possible. All together, we have over four hours of our usual targeted and remote sensing activities, as well as over 12 hours of overnight APXS integrations.
Mastcam is spending much of its time today looking off in the distance, particularly focusing on the potential boxwork structures that we’re driving towards. These structures get two dedicated mosaics, totaling 42 images between the two of them. Mastcam will also observe “Mishe Mokwa” (a small butte about 15 meters, or 49 feet, to our south) and some bedrock troughs in our workspace, and will take two tau observations to characterize the amount of dust in the atmosphere.
ChemCam has just one solo imaging-only observation in this plan: an RMI mosaic of Texoli butte off to our east. ChemCam will be collaborating with APXS to take some passive spectral observations (i.e., no LIBS) to measure the composition of the atmosphere. Mastcam and ChemCam will also be working together on observations of LIBS activities. This plan includes an extravagant three LIBS, on “Orocopia Mountains,” “Dripping Springs,” and “Mountain Center.” Both Mastcam and ChemCam also have a set of “dark” observations intended to characterize the performance of the instruments with no light on their sensors, something that’s very important for properly calibrating their measurements.
Our single set of arm activities includes APXS, DRT, and MAHLI activities on “Camino Del Mar” and “Mount Baden-Powell,” both of which are bedrock targets in our workspace.
Of course, I can’t forget to mention the collection of Navcam observations that we have in this plan to monitor the environment. These include a 360-degree survey looking for dust devils, two line-of-sight activities to measure the amount of dust in the air within Gale, and three cloud movies. As always, we’ve also got a typical collection of REMS, RAD, and DAN activities throughout.

On the night of Friday, May 16, something extraordinary lit up the skies over the American Southwest. A brilliant, fast-moving streak of light that captivated onlookers from Arizona to Colorado.
Witnesses in towns such as Safford, Fountain Hills, and Payson, as well as regions of New Mexico and Colorado, were left asking the same question: What exactly did we just see?
Speculation spread rapidly. Some suggested a Chinese rocket launch earlier that day could be responsible, possibly placing satellites into orbit. Others floated more exotic theories: perhaps STEVE, a rare atmospheric light phenomenon similar to the aurora borealis, or even a “light pillar,” formed when light reflects off high-altitude ice crystals.
Attempts to reach officials at Luke Air Force Base near Phoenix, Davis-Monthan Air Force Base in southern Arizona, and Kirtland Air Force Base in Albuquerque have so far yielded no response.
What if it wasn’t a rocket plume from a Chinese launch at all? What if something entirely different passed near our planet, like a comet or UFO, or perhaps it was a test of a space-based weapon or a directed-energy system?
Whatever it may have been, it remains a strange phenomenon, leaving many to wonder what truly streaked across the sky.

A science team has combined data from the NASA/ESA/CSA James Webb Space Telescope and the Keck II telescope to see evidence of cloud convection on Saturn’s moon Titan in the northern hemisphere for the first time. Most of Titan’s lakes and seas are located in that hemisphere, and are likely replenished by an occasional rain of methane and ethane. Webb also has detected a key carbon-containing molecule that gives insight into the chemical processes in Titan’s complex atmosphere.
