What carved this long, winding line on Mars? NASA has the answer
A stunning image captured by NASA's Mars Reconnaissance Orbiter (MRO) has unveiled a long and winding trail on the Martian surface, marking the path of Curiosity, NASA's rover. The photograph, taken on February 28, 2025, showcases the rover in action, leaving behind tracks as it heads toward a region believed to reveal signs of ancient groundwater activity. The trail, extending approximately 1,050 feet (320 meters), is expected to remain visible for months before Martian winds gradually erase it. This image, taken from orbit, also marks the first-ever mid-drive photo of Curiosity.
NASA Captures Curiosity rover in motion across Mars for the first time
NASA's Curiosity rover is often seen in images taken from the surface or from space, but this latest photograph is the first to capture the rover while it is actively driving across Mars. The image, taken by the HiRISE camera aboard the Mars Reconnaissance Orbiter, shows the rover as a small speck in the distance, with a visible trail marking its journey over the terrain.

Features of the winding trail
The trail left by Curiosity's wheels is a remarkable feature in the Martian landscape. Spanning over 1,050 feet, the tracks are the result of 11 separate rover drives that began on February 2, 2025. As Curiosity moves at a top speed of 0.1 mph (0.16 kph), these tracks are expected to remain visible for months before the harsh Martian winds gradually erase them. The rover's journey is a testament to the long-term impact of its exploration on the surface of the Red Planet.
What is the destination of Curiosity
Curiosity is heading toward a scientific target believed to hold critical clues about Mars' past. The rover is en route to a region featuring "boxwork" rock formations, which scientists suspect may have been shaped by ancient groundwater activity billions of years ago. By studying this area, Curiosity's team hopes to gain a better understanding of Mars' ancient environment and the possibility of past life on the planet.
Challenges of navigating Mars
Mars presents unique challenges for Curiosity's daily operations, particularly with its unpredictable terrain. The rover's speed and path are determined by a combination of terrain difficulties and pre-planned commands from engineers at NASA's Jet Propulsion Laboratory. Every day, the rover's movements are meticulously planned to ensure it makes steady progress toward its scientific objectives while dealing with the challenges of Mars' surface.

A milestone in Curiosity's mission
Launched in 2011, Curiosity has been exploring Mars since its landing in 2012. As part of NASA's broader Mars Exploration Program, the rover has provided invaluable data about the planet's geology, climate, and habitability. This latest image captured by the Mars Reconnaissance Orbiter highlights not only the rover's impact on the Martian landscape but also its ongoing role in uncovering the mysteries of Mars, helping to pave the way for future exploration and human missions.

Gp Capt. Shukla shares experience of life aboard ISS with students
Group Captain Shubhanshu Shukla, who is aboard the International Space Station (ISS) had a brief interaction with students who had gathered at the U.R. Rao Satellite Centre (URSC) here on Friday. He interacted with the student community via ham radio which lasted about 10 minutes. The interaction overseen by the Amateur Radio on the ISS (ARISS) saw the participation of approximately 70 students who posed questions on the Indian astronauts journey to the space station and daily routine in the orbiting laboratory. 'One-and-a-half days (journey to the ISS) and thereafter you get to see the ISS... It was very exciting to see and the entire process of how the capsule approaches the station and then positions itself right in line with the docking port and thereafter goes ahead and docks into the port. It was a very, very exciting moment for me,' Gp Capt. Shukla said replying to a question. His Axiom-4 mission (Ax-4) to the International Space Station (ISS) was launched on June 25, 2025, from NASA's Kennedy Space Center in Florida. After a 28-and-a-half-hour journey on the ISS Dragon spacecraft, Gp Capt. Shukla and other crew members reached ISS. He also spoke about the complex docking process. 'So when we landed in the space station, there were two crew members who were able to reach the docking port. And thereafter you get to see the International Space Station, which is going to be your home for the next 14 days,' he said. The Gp Capt. also spoke about the experiments he has been conducting in the space station and how sleeping is a challenge there. 'We have to tie our sleeping bags,' he said.

World's Largest Mars Rock Ever Found Could Sell For $4 Million At Sotheby's
A massive Martian meteorite, believed to be the largest ever discovered on Earth, is set to go under the hammer at a Sotheby's auction later this month. The rock, officially named NWA-16788, weighs an impressive 24.67 kilograms (54.39 pounds), making it approximately 70% larger than the previous record-holder, Taoudenni 002, which was found in Mali in 2021 and weighed 14.51 kg. The rare meteorite was discovered in November 2023 by a meteorite hunter in the Agadez region of Niger, an area typically known for dinosaur fossils rather than space rocks. A sample of the meteorite was sent to the Shanghai Astronomy Museum, which confirmed its Martian origin. Experts now estimate that this one-of-a-kind specimen could sell for up to US$4 million, attracting interest from collectors and scientific institutions alike. The sale offers a unique opportunity to own a piece of Mars without leaving Earth. "NWA 16788 is covered in a reddish-brown fusion crust, giving it an unmistakable Martian hue. 'Regmaglypts', or surface depressions formed by frictional heating during rapid descent through Earth's atmosphere, are also visible on the surface of the meteorite,' the Sotheby's listing explains."NWA 16788 shows minimal terrestrial weathering, indicating that its physical and chemical makeup have not been significantly altered since its arrival in the Sahara Desert. In other words, NWA 16788 is likely a relative newcomer here on Earth, having fallen from outer space rather recently." The meteorite will go under the hammer at Sotheby's New York on July 16. For some, the fact that the meteorite is being sold rather than donated to science is cause for concern. "It would be a shame if it disappeared into the vault of an oligarch. It belongs in a museum, where it can be studied, and where it can be enjoyed by children and families and the public at large," Steve Brusatte, a professor of paleontology and evolution at Scotland's University of Edinburgh, told CNN on Wednesday. But for Julia Cartwright, a planetary scientist and Independent Research Fellow in the Institute for Space/School of Physics & Astronomy at the University of Leicester, England, there is a balance to be struck. "Ultimately, if there was no market for searching, collecting and selling meteorites, we would not have anywhere near as many in our collections - and this drives the science!" she told CNN on Wednesday, describing a "symbiotic relationship" between researchers and collectors.

Shubhanshu Shukla says excitement to do more experiments posing difficulty to fall asleep
Shubhanshu Shukla, the first Indian astronaut to reach the International Space Station (ISS), Friday spoke with Indian students during his first ham radio interaction from onboard the space laboratory. 'The most difficult task is to go to sleep, because of the excitement and wanting to do more and more experiments…,' he said. 'I am doing a lot of experiments and these are challenging and exciting. All of these experiments have been planned by ISRO-NASA. But there are a few that I particularly like, especially the one on stem cells. We know there is limited time (onboard the ISS) but we want to do more and more (experiments). But we need to get rest to do the experiments,' said Shukla, along with demonstrating maneuvers and space-moves to be done to get tasks done. He also showed students his sleeping bag. Shukla was live on ham radio for less than ten minutes when the ISS was passing close to the horizon around 3.47pm on Friday, July 4. The ham radio communication was made to the UR Rao Satellite Centre in Bengaluru via telebridge (partly phone-partly ham connection), with the ground station located in Greenbelt, Maryland, US. Shukla was given a set of select questions prepared by students from all over India, who were shortlisted under three categories. Nearly 145 students joined live from Thiruvananthapuram and a similar number connected from Lucknow and Bengaluru. As the ISS orbits the Earth at an average speed of over 27,000 km/hr making 16 orbits/day, the best possible bandwidth for establishing ham radio communication generally lasts for just five to eight minutes. Shukla's voice was filled with excitement as he took on the questions and gave quick, short answers each ending with 'over' — hinting at the next question he was proceeding to take up. Shukla spoke about the ride onboard SpaceX's Crew Dragon on June 25, the tiny capsule, the accelerating speeds and the one-and-a-half days of 'floating' in space till docking at the ISS and how his body faced hardships in adapting to the new conditions in space. The Axiom-4 mission is led by NASA, in partnership with ISRO and the European Space Agency. On the role of this international collaboration, Shukla said: ' I think international collaboration is the key for the success of a mission to the ISS and space. Even for our mission, Axiom-4, ISRO, NASA and ESA… everyone came together to make this mission happen. I have realised the power of global collaboration. Working with many people of different nationalities is an entirely exciting experience. So definitely, global collaboration is the key and I look forward to more such missions.' Indian food also touched 'new heights' with Shukla's Ax-4. He is carrying with him three delicacies – aamaras, moong dal halwa, and gajar halwa. 'These foods were prepared by ISRO in collaboration with the Defence Research and Development Organisation (ISRO). I shared these foods with everybody and they loved and appreciated it.' The Earth's view from space, Shukla said, was the most beautiful one from onboard the ISS. 'The most exciting part about being in space is looking back at earth from the vantage point. It is big, very beautiful and reminded me of how fortunate we are to be on this planet. It is also a realisation of how important this planet is with everything we have.' Shukla will make the second and final communication using ham radio at 2.08pm on July 8 with the Human Spaceflight Center at the North Eastern Space Applications Centre (NESAC) in Meghalaya.
