A recent picture by NASA can leave us wondering. The aerial shot shows a vast expanse of Mars surface and is taken by NASA’s Ingenuity Mars Helicopter on its 11th flight on the planet. Look close into the photo. Can you see NASA’s Perseverance Rover amidst the seemingly monochrome desert of the Red Planet? It’s right there and NASA’s scientists are all gaga to see their newest rover on the planet at work from a distance of 1,600 feet and a height of 39 feet. Ingenuity snapped many photos of Mars on its recent flight. Most of the pictures showed geographical features like sand dunes, boulders, and rocky lands in the South Séítah region of Jezero Crater. But a few of the photos, when zoomed in, can show Perseverance working on its first science campaign.

On NASA’s website, Robert Hogg, Senior Systems Engineer at NASA, was quoted saying, “Ingenuity’s aerial images are awesome – but even better when you get to play ‘Where’s Perseverance?’ with them.” He added, “Once you find our rover and zoom in, you can make out some details, like the wheels, remote sensing mast, and the MMRTG (Multi-Mission Radioisotope Thermoelectric Generator) on the aft end.”

But where do we find the tiny speck amidst the sand dunes? Any guesses where Perseverance might be? If we look at one photo, we distinctly see Ingenuity’s shadow. Straight up from it, just beyond and right of South Seitah’s dune we see a “bright white speck”. If we zoom in on that speck, that’s the Mars Rover we are looking for.

According to NASA’s website, Ingenuity’s 11th flight was designed to keep it ahead of the rover. Its goal was to photograph geological features where the rover couldn’t get.

Meanwhile, Mars 2020 Perseverance mission rover was doing its work related to astrobiology, searching for signs of ancient microbial life on the planet. The rover is meant to collect data about the planet’s geology and past climate. NASA’s website says the Perseverance mission will be “the first mission to collect and cache Martian rock and regolith”.

NASA's Perseverance Rover Observes Googly Eye Eclipse on Mars

NASA’s Perseverance rover which is positioned in the Jezero Crater on Mars, recently observed a remarkable celestial event as the moon Phobos drifted across the Sun. Captured on September 30, this moment offered a rare glimpse into Mars’ sky, where the unique “googly eye” effect of the eclipse unfolded for the rover’s Mastcam-Z camera. The video, released by NASA, illustrates the interplay of Martian moon orbits and provides valuable information on Phobos’ trajectory and its gradual shift towards Mars.

Unexpected Eclipse Creates ‘Googly Eye’ View on Mars

Perseverance, which has been observing Mars’ surface and sky since 2021, recorded the silhouette of Phobos moving rapidly across the Sun’s face from Mars’ western Jezero Crater. Phobos, the larger of Mars’ two moons, created a distinct “googly eye” visual effect as it partially blocked sunlight, a phenomenon not typically visible from Earth. The eclipse, captured on the mission’s 1,285th sol (Martian day), highlights Phobos’ swift orbit, which takes just 7.6 hours to complete a full circle around Mars. Due to its close orbit, Phobos regularly crosses Mars’ sky, allowing for these brief transits which last only about 30 seconds each.

Phobos’ Eerie Path and Future on Mars

Phobos, named by astronomer Asaph Hall in 1877 after the Greek deity associated with fear, measures about 27 kilometres at its widest. Unlike Earth’s larger moon, Phobos appears far smaller in the Martian sky. Its orbit brings it closer to Mars with time, which scientists predict will eventually cause Phobos to collide with the Martian surface within the next 50 million years. Past eclipses of Phobos, also recorded by other Mars rovers like Curiosity and Opportunity, continue to contribute essential data for understanding Mars’ moons and their shifting orbits.

Perseverance’s Mission and Future Mars Exploration

As part of NASA’s Mars 2020 mission, Perseverance focuses on exploring Martian geology and astrobiology. The mission, managed by NASA’s Jet Propulsion Laboratory (JPL), is the first to collect samples of Mars’ surface material, which are intended to be retrieved in future joint missions with the European Space Agency (ESA). Perseverance’s Mastcam-Z, developed with support from Arizona State University, Malin Space Science Systems, and the Niels Bohr Institute, plays a crucial role in gathering high-resolution imagery to support geological studies. This mission aligns with NASA’s broader objective of preparing for human exploration on Mars, beginning with the Artemis missions to the Moon.

South Korea teams up with NASA to send solar research tool to ISS

South Korea’s space agency announced plans on Friday to launch a solar coronagraph to the International Space Station (ISS) in a collaborative mission with NASA. Developed as part of the Coronal Diagnostic Experiment (CODEX), this instrument is set to observe and gather data on the Sun’s corona and the solar wind as well as the stream of charged particles that flows from the Sun’s outer atmosphere. The CODEX device is scheduled to be launched aboard SpaceX’s Falcon 9 from Florida’s Kennedy Space Center on Monday, as reported by Yonhap News Agency.

Bilateral Project to Examine Solar Atmosphere

The CODEX project represents a very important collaboration between the Korea Aerospace Research Institute (KASA) and NASA, with CODEX marking a pioneering achievement as the world’s first coronagraph equipped to measure temperature, velocity, and density within the solar wind. Once aboard the ISS, CODEX will be mounted on the station’s express logistics carrier, allowing for approx 55 minutes of solar observation in each 90-minute orbit around Earth. This data is expected to enhance researchers’ understanding of the solar wind, potentially aiding in space weather forecasting efforts.

South Korea’s Expanded Cooperation with NASA

Alongside the CODEX project, South Korea and the United States have broadened their partnership in space exploration. KASA and NASA signed a statement of cooperation, focusing on research initiatives including the Artemis lunar exploration programme. KASA’s involvement with the Artemis project includes studies on sustainable lunar exploration and advancements in Mars mission preparations. With this agreement, South Korea has become the fifth nation to officially collaborate with NASA on such initiatives.

Pioneering Studies and Technological Advancements

Under the framework of this agreement, South Korea and the US will work together on a variety of feasibility studies related to lunar landers, as well as advancements in communication, navigation, and astronaut support systems. In addition, collaborative efforts will span lunar surface science, autonomous power, robotic systems, and cis-lunar space operations—the area between Earth and the Moon.

NASA's satellite reveals fascinating tsunami data in Greenland

An unprecedented nine-day tsunami following a significant rockslide in Greenland’s Dickson Fjord was recently recorded by the international Surface Water and Ocean Topography (SWOT) satellite, a collaborative mission by NASA and France’s Centre National d’Études Spatiales (CNES). The event, which took place in September 2023, saw a unique pattern of seismic waves resonate around the world, marking one of the rare instances where satellite data captured a prolonged natural phenomenon with such clarity.

Satellite’s Breakthrough Detection in Remote Fjord

As per a report by NASA, the rockslide unleashed over 25 million cubic meters of rock and ice into the fjord, displacing the water and creating a massive wave that moved rhythmically between the fjord walls every 90 seconds for nine consecutive days. NASA’s Jet Propulsion Laboratory scientist Josh Willis highlighted this as a first, saying, “SWOT’s technology allowed us to see the wave contours, something we couldn’t achieve before.” The water levels on the northern side of Dickson Fjord rose as high as 1.2 metres in contrast to the southern side, emphasising the powerful impact of the rockslide.

Advanced Technology for Global Hazard Monitoring

At an altitude of around 900 kilometres, SWOT utilises a Ka-band Radar Interferometer (KaRIn) to measure surface water height with precision. This technology captured the event’s effects in the confined fjord setting, which conventional altimeters could not do due to their larger footprint. Nadya Vinogradova Shiffer, a scientist at NASA Headquarters, noted that this capability highlights SWOT’s potential for monitoring hazards, contributing to preparedness and disaster risk reduction.

Innovative Partnership in Satellite Research

Since its launch in December 2022, SWOT has been instrumental in mapping global water levels. Developed with contributions from the Canadian and UK space agencies, NASA leads the mission’s U.S. operations, including the KaRIn instrument, with CNES managing various onboard systems and support. The data collected promises ongoing contributions to scientific understanding of Earth’s water dynamics.
