Awesome Eruptions

A new study suggests some of the biggest volcanic eruptions in the history of the Solar System happened on Mars over a period of 500 million years, ending about 3 billion years ago.

Such a period would have completely reshaped the planet.

Martian Dust Storm

The dust storm on Mars has become a global event.

Curiosity, which is nuclear powered, is fine, but Opportunity, which is solar powered, is shut down for now.

Hackers

According to reports, China has hacked into American satellites and defense contractors.

The hackers could possibly have changed the satellites' orbits.

Ceres

New analysis of data from the Dawn spacecraft suggests Ceres has a significantly larger amount of organic molecules than originally thought.

Ceres continues to be a fascinating little world.

Space Force

President Trump has begun the process of creating a U. S. space force.

He also said the U. S. will establish a permanent presence on the Moon and go to Mars.

Space Laser

Russia would like to solve the space junk problem by blasting junk to smithereens with a powerful laser.

Of course, such a laser could also destroy operational satellites.

Hawking

At the memorial for Stephen Hawking, his voice was beamed in the direction of a black hole.

It was meant as a tribute, but it was also ironic. Hawking warned against beaming signals into space lest we attract the attention of dangerous aliens.
