Leaving Pluto in the dust: New Horizons probe gearing up for epic crossing of ‘termination shock’

NeRD

NASA’s New Horizons spacecraft conducted the first and only flyby of the Pluto system, culminating at the closest approach of that distant world in July 2015. Sailing onward, the probe carried out a Jan. 1, 2019 flyby of Arrokoth, a Kuiper Belt Object, or KBO, located in a region of space beyond Neptune called the Kuiper Belt. There are scads of other icy worlds residing in the Kuiper Belt, celestial leftovers from the formation of our solar system. For New Horizons, the gathering of more exploration science is, pun intended,…

In the Starlight: Portia Keyes Procures Mission-Critical Support

NeRD

One semester as a NASA Pathways intern was enough to inspire Portia Keyes to sign up for a Russian language class at college. After interning in the Johnson Space Center’s Office of Procurement, Keyes hoped to someday use her new language skills in support of the International Space Station Program. Now, 12 years later, Keyes is the deputy manager of the procurement office for the International Space Station and Commercial Low Earth Orbit Development Programs. That means she is responsible for implementing and overseeing acquisition solutions that enable the purchasing…

Black holes snacking on small stars create particle accelerators that bombard Earth with cosmic rays

NeRD

Using 16 years of data from NASA’s gamma-ray detecting Fermi spacecraft, astronomers have discovered that “microquasars,” systems in which a black hole is slowly devouring a star, may be small, but they pack one heck of a punch. Despite their diminutive nature, this research suggests even microquasars snacking on small stars can have an impressive cosmic influence, becoming powerful natural particle accelerators. This means black holes indulging in stellar meals of all sizes could be responsible for a higher-than-suspected amount of high-energy charged particles called “cosmic rays,” which are constantly…

5 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) Astronaut Jeanette Epps extracts DNA samples from bacteria colonies for genomic analysis aboard the International Space Station’s Harmony module. NASA In an effort to learn more about astronaut health and the effects of space on the human body, NASA is conducting a new experiment aboard the International Space Station to speed up the detection of antibiotic-resistant bacteria, thus improving the health safety not only of astronauts but patients back on Earth. Infections caused by antibiotic-resistant bacteria can be difficult…

Lego Marvel Logo & Minifigures set review

NeRD

Essential info: Price: $99.99/£89.99 Model number: 76313 Number of pieces: 931 Dimensions: 4 x 11 x 2.5 inches (11 x 28 x 7cm) Recommend age: 12+ I don’t think any other Lego set has been quite as ‘what you see is what you get’ as the Marvel Logo & Minifigures set. As the name suggests, this literally is a 3D box with the Marvel logo on the front. It’s not exactly inspiring. But it is a solid model, and with some interesting building techniques, it’s fairly fun to build too.…
