A new tech to cool down ❄️ microchips will be tested in zero gravity for the 1st time ever on a Blue Origin launch! 🚀https://go.nasa.gov/2InqOFp

Tightly-packed high-tech electronics easily overheat – especially in new 3-D circuitry where computer chips are literally stacked on top of each other. Thermal engineer Franklin Robinson's new technique is called "microgap cooling." This innovation removes heat by flowing a coolant through embedded, rectangular-shaped channels within or between the heat-generating devices.

Robinson’s flight experiment also features “flow boiling,” where, as its name implies, the coolant boils as it flows through the tiny gaps. According to Robinson, the technique offers a higher rate of heat transfer, which keeps devices cooler and, therefore, less likely to fail due to overheating.

Mr. Robotic Arm goes to Washington!

Earlier this week NASA's Satellite Servicing Projects Division attended NASA Tech Day on the Hill to talk NASA Technology.

LIVE from the International Space Station! Maryland students will chat with astronauts Ricky Arnold, a Maryland native, and Drew Feustel tomorrow at 10:35 a.m. ET: http://go.nasa.gov/2qGOGgj

Speaking with Anne Arundel County Public Schools (AACPS)'s South River High School in Edgewater, Maryland, the 20-minute, Earth-to-space call will air live on http://go.nasa.gov/ntv. The Expedition 55 astronauts will answer questions about life aboard the space station, NASA’s deep space exploration plans and conducting science in space.

Linking students and teachers directly to astronauts aboard the space station provides unique, authentic experiences designed to enhance learning, performance and interest in science, technology, engineering and mathematics (STEM). This in-flight education downlink is an integral component of NASA’s Year of Education on Station, which provides extensive space station-related resources and opportunities to students and educators. Astronauts living in space on the orbiting laboratory communicate with the Mission Control Center on Earth 24 hours a day through the Space Network's Tracking and Data Relay Satellites (TDRS).

Where do we go from here?

As NASA astrophysicists like Aki Roberge propose groundbreaking NEW science missions, NASA technologists will need to invent new instruments to DO the science.

Flown by the U.S. Air Force, the custom shipping container holding NASA's Parker #SolarProbe arrived in Florida on April 3 in advance of the mission’s launch to the Sun on July 31. https://www.nasa.gov/feature/goddard/2018/nasa-s-mission-to-touch-the-sun-arrives-in-the-sunshine-state

Parker Solar Probe is humanity’s first mission to the Sun. After launch, it will orbit directly through the solar atmosphere – the corona – closer to the surface than any human-made object has ever gone. While facing brutal heat and radiation, the mission will reveal fundamental science behind what drives the solar wind, the constant outpouring of material from the Sun that shapes planetary atmospheres and affects space weather near Earth.

Hubble shows the spiral galaxy NGC 5714 about 130 million light-years away in the constellation of Boötes (the Herdsman). Its spiral arms are hard to see as NGC 5714 presents itself at an almost perfectly edge-on angle.

Discovered by William Herschel in 1787, NGC 5714 was host to a fascinating and rare event in 2003. A faint supernova appeared about 8,000 light-years below the central bulge of NGC 5714. Supernovae are the huge, violent explosions of dying stars. It was particularly interesting because its spectrum showed strong signatures of calcium.

Calcium-rich supernovae are rare and hence of great interest to astronomers. Astronomers still struggle to explain these particular explosions as their existence presents a challenge to both observation and theory. In particular, their appearance outside of galaxies, their lower luminosity compared to other supernovae, and their rapid evolution are still open questions for researchers.

Move over Elsa. For the first time ever NASA scientists have created a 3-D model of a melting snowflake. How might this research improve predictions of hazardous heavy and wet snow? #LetItSnow
