The 7 Rocky TRAPPIST-1 Planets May Be Made of Similar Stuff

Measuring the mass and diameter of a planet reveals its density, which can give scientists clues about its composition. Scientists now know the density of the seven TRAPPIST-1 planets with a higher precision than any other planets in the universe, other than those in our own solar system. (Credits: NASA/JPL-Caltech)

Precise measurements reveal that the exoplanets have remarkably similar densities, which provides clues about their composition.

PASADENA, Calif. (NASA PR) — The red dwarf star TRAPPIST-1 is home to the largest group of roughly Earth-size planets ever found in a single stellar system. Located about 40 light-years away, these seven rocky siblings provide an example of the tremendous variety of planetary systems that likely fill the universe.

SpaceX Dragon Returns ISS National Lab-sponsored Payloads to Earth

KENNEDY SPACE CENTER, Fla., April 7, 2020 (ISS National Lab PR) – SpaceX’s Dragon spacecraft successfully splashed down today off the coast of California, bringing back dozens of research investigations sponsored by the International Space Station (ISS) U.S. National Laboratory.

The successful splashdown and science return marks the completion of SpaceX’s 20th commercial resupply services (CRS) mission to the space station (contracted by NASA) to send critical research and supplies to the orbiting laboratory. The Dragon spacecraft spent approximately 30 days berthed to the space station before returning to Earth.

Greenland and Antarctica are melting – but how quickly and which areas are most affected? Nearly 20 years of satellite data provide key insights into these questions.


PASADENA, Calif. (NASA PR) — During the exceptionally warm Arctic summer of 2019, Greenland lost 600 billion tons of ice – enough to raise global sea levels by nearly a tenth of an inch (2.2 millimeters) in just two months, a new study shows.

CASIS, NIH Sponsor Human Physiology & Disease Experiments on ISS

KENNEDY SPACE CENTER, Fla., June 20, 2017 (CASIS PR The Center for the Advancement of Science in Space (CASIS) and the National Center for Advancing Translational Sciences (NCATS), part of the National Institutes of Health (NIH), today announced five grants have been awarded in response to a funding opportunity focused on human physiology and disease onboard the International Space Station (ISS) U.S. National Laboratory. Data from this research — which will feature “tissue chips” (or “organs-on-chips”) — will help scientists develop and advance novel technologies to improve human health here on Earth.

With CubeSats and other types of small satellites are being launched in increasing numbers, there’s a race on to develop new technologies to vastly improve their capabilities and extend their range to the moon, Mars and other deep space destinations.

NASA has been at the leading edge of this technology development effort. Last week, the space agency announced its plans to fund four small-satellite research projects. The projects include phase II funding for three Small Business Technology Transfer (STTR) Program proposals and one NASA Innovative Advance Concepts (NIAC) proposal.
