NASA's Perseverance rover is tackling a steep new challenge on Mars. The six-wheeled rover has spent the last 3 1/2 years roaming around the bottom of a crater. On Tuesday, it began climbing to the top. The rover will go up 1,000 feet (305 meters) to the rim of Jezero Crater to dig up rock samples. Since landing on the red planet in 2021, Perseverance has collected 22 rock core samples from the floor of the crater, which was once filled with water. The rover's samples may help scientists piece together what the planet's climate looked like billions of years ago and learn whether any ancient Martian life lurked. NASA is exploring ways to bring the rock samples to Earth. The bedrock at the rim of the crater might yield clues as to how rocky planets like Mars and Earth came to be, said Steven Lee with NASA's Jet Propulsion Laboratory in California. But the road ahead won't be easy. Perseverance will scale rocky terrain and slopes of up to 23 degrees on the months-long ...
ISRO on Saturday successfully demonstrated a new technology with Inflatable Aerodynamic Decelerator (IAD) that it said is a game-changer with multiple applications for future missions including to Mars and Venus. An IAD, designed and developed by ISRO's Vikram Sarabhai Space Centre (VSSC), was successfully test flown in a 'Rohini' sounding rocket from Thumba Equatorial Rocket Launching Station (TERLS). The IAD was initially folded and kept inside the payload bay of the rocket, according to the Bengaluru-headquartered Indian Space Research Organisation (ISRO). At around 84 km altitude, the IAD was inflated and it descended through atmosphere with the payload part of sounding rocket. The pneumatic system for inflation was developed by ISRO's Liquid Propulsion Systems Centre (LPSC), it said. The IAD has systematically reduced the velocity of the payload through aerodynamic drag and followed the predicted trajectory. "This is the first time that an IAD is designed specifically for spe
The United Arab Emirate's Mars Mission (EMM) and NASA's MAVEN probe have found "patchy" proton auroras in Mars' skies, providing new insights into the red planet's atmosphere. An aurora is a natural light display in a planet's sky, predominantly seen in high-latitude regions such as the northern lights, or the aurora borealis, seen from the Earth. The new aurora found by the team is formed when the solar wind directly impacts Mars' upper atmosphere and emits ultraviolet light as it slows down. It was discovered in snapshots of the dayside disk obtained by the Emirates Mars Ultraviolet Spectrometer (EMUS), which observes the planet's upper atmosphere. When the aurora occurs, small regions of the planet become much brighter, signifying intense localised energy in the atmosphere. "Our discovery of these patchy proton aurora adds a new kind of event to the long list of those currently studied by EMM and challenges our existing views of how the proton aurora on Mars' dayside are formed
