To guard against cyberattacks in space, researchers ask 'what if?'

If space systems such as GPS were hacked and knocked offline, much of the world would instantly be returned to the communications and navigation technologies of the 1950s. Yet space cybersecurity is largely invisible to the public at a time of heightened geopolitical tensions.
Cyberattacks on satellites have occurred since the 1980s, but the global wake-up alarm went off only a couple of years ago. An hour before Russia's invasion of Ukraine on Feb. 24, 2022, its government operatives hacked Viasat's satellite-internet services to cut off communications and create confusion in Ukraine.
I study ethics and emerging technologies and serve as an adviser to the U.S. National Space Council. My colleagues and I at California Polytechnic State University's Ethics + Emerging Sciences Group released a U.S. National Science Foundation-funded report on June 17, 2024, to explain the problem of cyberattacks in space and help anticipate novel and surprising scenarios.
Space and you
Most people are unaware of the crucial role that space systems play in their daily lives, never mind military conflicts.

A network of ground stations around the world, including two owned by ESA, will track the debut flight of Europe’s new Ariane 6 rocket. They will monitor key phases of the flight and gather telemetry and video that will be used to analyse the rocket’s performance and optimise future launches.
Firefly Aerospace aims to launch eight CubeSat satellites after scrub

Firefly Aerospace will try to get its Alpha rocket carrying eight CubeSat satellites into space on Tuesday night from California's Vandenberg Space Force Base after the mission was scrubbed on Monday.
The satellites are being put into space under NASA's Launch Services Program Venture. Officials blamed a "last minute" ground systems issues led to the mission's pause on Monday.
"O Crew inside NASA's Mars habitat simulator to exit after more than a year

The first volunteer crew, to live for more than a year inside NASA's Mars habitat at the Johnson Space Center in Houston, will exit the simulated Red Planet ground mission on Saturday.
Crew members Kelly Haston, Anca Selariu, Ross Brockwell and Nathan Jones will be greeted with a short welcome ceremony at about 5 p.m. EDT, which can be viewed on NASA+, NASA Television, the NASA app and Blue Origin, Stoke Space selected by U.S. Space Force to compete for small satellite missions

Technicians lift NASA's Orion spacecraft out of the Final Assembly and System Testing cell on June 28, 2024. The integrated spacecraft, which will be used for the Artemis II mission to orbit the moon, has been undergoing final rounds of testing and assembly, including end-to-end performance verification of its subsystems and checking for leaks in its propulsion systems.
A 30-ton crane returned Orion into the recently renovated altitude chamber where it underwent electromagnetic testing.
The spacecraft will now undergo a series of tests that will subject it to a near-vacuum environment by removing air, thus creating a space where the pressure is extremely low.
This results in no atmosphere, similar to the one the spacecraft will experience during future lunar missions.
The data recorded during these tests will be used to qualify the spacecraft to safely fly the Artemis II astronauts through the harsh environment of space.

Could we replace Ingenuity with a swarm of robotic bees?
Wednesday, 03 July 2024 16:43 Write a comment
Humans finally achieved controlled flight on another planet for the first time just a few years ago. Ingenuity, the helicopter NASA sent to Mars, performed that difficult task admirably. It is now taking a well-deserved rest until some intrepid human explorer someday comes by to pick it up and hopefully put it in a museum somewhere.
But what if, instead of a quadcopter, NASA used a series of flexible-wing robots akin to bees to explore the Martian terrain? That was the idea behind the Marsbee proposal by Chang-Kwon Kang and his colleagues at the University of Alabama at Huntsville. The project was supported by a NASA Institute for Advanced Concepts (NIAC) grant back in 2018—let's see what they did with it.
The concept was initially inspired by work at the University of Tokyo on a dragonfly-like micro aerial vehicle (MAV). It is one of the few drones able to fly in Earth's gravity using flexible wings that flap.

Proba-3’s new view on space weather

Space weather can affect satellites in orbit, trigger geomagnetic storms on Earth and interfere with ground infrastructure. We need to understand it better, and the best way to do that is look at where it comes from.
The Sun’s corona, its upper atmospheric layer, gives rise to the solar wind and is where coronal mass ejections are spawned: massive outward explosions of charged plasma. ESA’s Proba-3 double-satellite mission will use formation flying to open up sustained coronal views. Mimicking a total solar eclipse, one satellite will block out the fiery face of the Sun by casting a shadow onto the other.
