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
(14 Nov. 2013) — Japan Aerospace Exploration Agency astronaut Koichi Wakata, Expedition 38 flight engineer, prepares to exercise in the Tranquility node of the International Space Station, using the advanced Resistive Exercise Device (aRED).

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.

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.

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
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
