'Sloshing' Supernova Sheds Light on Star's Death

By tracing radioactive material in the remains of a nearby exploded star, scientists have a new understanding of what happened in the star’s final moments and how similar explosions create the calcium, gold, iron and other elements spread throughout the cosmos. Read more

Next time when you’re at the gym, complaining about the mess of the dumbbells, spare a thought for the ISS astronauts who NEED to work out to avoid the worst cases of muscle atrophy. 

The “before” and “after” shots of Curiosity’s wheels are pretty striking. Although the rover’s wheels are designed to sustain significant damage without putting the mission at risk, mission managers are assessing a recent acceleration in perforations and rips in the wheels’ aluminum.

Rough Roving: Curiosity’s Wheel Damage ‘Accelerated’

In May, Discovery News reported the dramatic signs of wear and tear on Mars rover Curiosity’s wheels. The aircraft-grade aluminum material appeared scratched, dented, even punctured. At the time, lead rover driver Matt Heverly said that the damage was to be expected. “The ‘skin’ of the wheel is only 0.75mm thick and we expect dents, dings, and even a few holes due to the wheels interacting with the rocks,” he said via email. Despite the assurances that the holes were just a part of Curiosity’s mission, there seems to be increasing concern for the wheels’ worsening condition after the one-ton robot rolled over some craggy terrain.

Mars Rover Finds Ancient Life-Supporting Lakebed

The site where NASA’s Mars rover Curiosity landed last year contains at least one lake that would have been perfectly suited for colonies of simple, rock-eating microbes found in caves and hydrothermal vents on Earth. Read more

The Right Stuff: Scott Carpenter’s Mission

Last week, we lost a NASA astronaut legend. Here is his legacy.

It’s Official: Voyager 1 is an Interstellar Probe

After a 35-year, 13-billion mile journey, NASA’s Voyager 1 spacecraft become the first human-made object to reach interstellar space, new evidence from a team of scientists shows.

“It’s kind of like landing on the moon. It’s a milestone in history. Like all science, it’s exploration. It’s new knowledge,” long-time Voyager scientist Donald Gurnett, with the University of Iowa, told Discovery News. Read more

Kraft to NASA: Get Out of this Solar System

During a powerful interview with the Houston Chronicle this week, NASA’s first manned spaceflight director Chris Kraft gave his unabashed opinion about the current state of NASA and its future plans. Read more.

NASA Probe to Solve Mars Atmosphere Mystery

The Mars Atmosphere and Volatile Evolution mission, nicknamed MAVEN, is designed to provide some answers as to why Mars’ atmosphere was stripped into space. From its orbital perch around Mars, MAVEN will track how the solar wind picks away at the planet’s thin atmosphere. The information will then be used to create computer models that move backward in time so scientists can determine when the planet was most suited for life and how long that period lasted. Read more

Year One: Mars Rover Curiosity’s Key Discoveries

Can you believe it’s been a year since Curiosity landed on Mars? Although its mission has only just begun, let’s take a quick look at some of the cool science the Mars Science Laboratory has been doing in the Mars dirt for the past 12 months.
