Hijacked satellites, orbiting weapons: Space new battlefield in this era

As Russia held its Victory Day parade this year, hackers backing the Kremlin hijacked an orbiting satellite that provides television service to Ukraine. Instead of normal programing, Ukrainian viewers saw parade footage beamed in from Moscow: waves of tanks, soldiers and weaponry. The message was meant to intimidate, and it was also an illustration that 21st century war is waged not just on land, sea and air but also in cyberspace and the reaches of outer space. Disabling a satellite could deal a devastating blow without a single bullet, and it can be done by targeting the satellite's security software or disrupting its ability to send or receive signals from Earth. If you can impede a satellite's ability to communicate, you can cause a significant disruption, said Tom Pace, CEO of NetRise, a cybersecurity firm focused on protecting supply chains. He served in the Marines before working on cyber issues at the Department of Energy. Think about GPS, he said. Imagine if a population l

Nasa powers down two instruments on Voyager spacecraft to save energy

NASA is switching off two science instruments on its long-running twin Voyager spacecraft to save power. The space agency said Wednesday an instrument on Voyager 2 that measures charged particles and cosmic rays will shut off later this month. Last week, NASA powered down an instrument on Voyager 1 designed to study cosmic rays. The energy-saving moves were necessary to extend their missions, Voyager project manager Suzanne Dodd at the NASA Jet Propulsion Laboratory said in a statement. The twin spacecraft launched in 1977 and are currently in interstellar space, or the space between stars. Voyager 1 discovered a thin ring around Jupiter and several of Saturn's moons, and Voyager 2 is the only spacecraft to visit Uranus and Neptune. Each spacecraft still has three instruments apiece to study the sun's protective bubble and the swath of space beyond. Voyager 1 is over 15 billion miles (24.14 billion kilometers) from Earth and Voyager 2 is over 13 billion miles (20.92 billion ...

Crew of Nasa's earthbound simulated Mars mission emerge after a year

The crew of a NASA mission to Mars emerged from their craft after a yearlong voyage that never left Earth. The four volunteer crew members spent more than 12 months inside NASA's first simulated Mars environment at Johnson Space Center in Houston, coming out of the artificial alien enviroment Saturday around 5 p.m. Kelly Haston, Anca Selariu, Ross Brockwell and Nathan Jones entered the 3D-printed habitat on June 25, 2023, as the maiden crew of the space agency's Crew Health and Performance Exploration Analog project. Haston, the mission commander, began with a simple, Hello. It's actually just so wonderful to be able to say hello' to you all, she said. Jones, a physician and the mission medical officer, said their 378 days in confinement went by quickly. The quartet lived and worked inside the space of 1,700 square feet (157 square meters) to simulate a mission to the red planet, the fourth from the sun and a frequent focus of discussion among scientists and sci-fi fans alike ...

Nasa to soon provide advanced training to Indian astronauts: Garcetti

NASA will soon provide advanced training to Indian astronauts, with the goal of mounting a joint effort to the International Space Station, a top American diplomat said Friday.? US Ambassador to India Eric Garcetti made these remarks while speaking at the "US-India Commercial Space Conference: Unlocking Opportunities for US & Indian Space Startups," hosted by the US-India Business Council (USIBC) and the US Commercial Service (USCS) in Bangalore. NASA will soon provide advanced training to Indian astronauts, with the goal of mounting a joint effort to the International Space Station, hopefully, this year or shortly thereafter, which was one of the promises of our leaders' visit together. And soon we will launch the NISAR satellite from ISRO's Satish Dhawan Space Center to monitor all resources, including ecosystems, the Earth's surface, natural hazards, sea level rise, and the cryosphere, Garcetti said, according to a USIBC press statement issued here. You see whether it's the ...

Nasa satellite blasts off to survey oceans, atmosphere of a warming Earth

NASA's newest climate satellite rocketed into orbit Thursday to survey the world's oceans and atmosphere in never-before-seen detail. SpaceX launched the Pace satellite on its USD 948 million mission before dawn, with the Falcon rocket heading south over the Atlantic to achieve a rare polar orbit. The satellite will spend at least three years studying the oceans from 420 miles (676 kilometres) up, as well as the atmosphere. It will scan the globe daily with two of the three science instruments. A third instrument will take monthly measurements. It's going to be an unprecedented view of our home planet," said project scientist Jeremy Werdell. The observations will help scientists improve hurricane and other severe weather forecasts, detail Earth's changes as temperatures rise and better predict when harmful algae blooms will happen. NASA already has more than two dozen Earth-observing satellites and instruments in orbit. But Pace should give better insights into how atmospheric ...
