Saving humanity – is space up to the job?
... more viable than drilling a hole to the core of Mars and implanting millions of tons of iron to create a ‘natural’ magnetic field. EDDE Vehicle Schematic, Showing Arrays, Conductor, Emitters, and Net Managers Mitigating climate change While looking...

The next ‘unthinkable’ – global disruption from a solar storm
...mass ejections (CMEs), accompanied by solar energetic particles (SEPs). Because of the interaction of CMEs with the Earth’s magnetic field, a geomagnetic storm can be generated. Three main types of space weather events are typically recognised: radio...

Solar astronomers "listening" to the Sun can now predict future sunspots
... Earth, millions of sound frequencies also bounce freely throughout the Sun’s interior, but when regions of strong magnetic fields appear, these perturb the sound waves causing a change in the wave signal measurements recorded on our planet...

Defending Earth against cosmic hazards
... four-satellite Magnetospheric Multiscale (MMS) mission are providing us more and more information about how Earth’s magnetic field is changing. The geomagnetosphere is about 15 per cent less effective in warding off the supercharged ions in a CME...

Terraforming Mars: from CFCs to Total Recall
... cosmic rays) incident on the surface of Mars. Such radiation is almost entirely blocked on Earth by the combination of Earth’s magnetic field and its relatively thick atmosphere. Humans living in cities on Mars might need to spend much of their time...
