Death of Chrysalis…

Topics: Astronomy, Astrophysics, NASA, Planetary Science WASHINGTON, Sept 15 (Reuters) – Call it the case of the missing moon. Scientists using data obtained by NASA’s Cassini spacecraft and computer simulations said on Thursday the destruction of a large moon that strayed too close to Saturn would account both for the birth of the gas giantContinue reading “Death of Chrysalis…”

WASP-39b and CO2…

Topics: Astrophysics, Chemistry, ESA, Exoplanets, James Webb Space Telescope, NASA The James Webb Space Telescope — already famous for its mesmerizing images of the cosmos — has done it again. The telescope has captured the first unambiguous evidence of carbon dioxide in the atmosphere of a planet outside the Solar System. The finding not only provides tantalizingContinue reading “WASP-39b and CO2…”

Studying UAPs…

Topics: Astrophysics, NASA, SETI I was startled, to say the least, that this story appears in Scientific American, and that NASA and theoretical astrophysicist Avi Loeb is interested in it. The nut job “giggle factor” has given way to curiosity about things humans cannot explain, and that bothers us as a species. My concern isContinue reading “Studying UAPs…”

HETs…

Topics: Applied Physics, Computer Modeling, NASA, Space Exploration, Spaceflight Abstract Hall effect thrusters operating at power levels in excess of several hundreds of kilowatts have been identified as enabling technologies for applications such as lunar tugs, large satellite orbital transfer vehicles, and solar system exploration. These large thrusters introduce significant testing challenges due to theContinue reading “HETs…”

Uhura to Proctor…

Topics: NASA, Space Exploration, Spaceflight, SpaceX, Star Trek Dr. King revealed to Nichols that TOS was the only show that he and his wife, Coretta, allowed their little children to stay up and watch. Further, he told Nichols what the show meant to him personally and detailed the importance of her having created a character with “dignityContinue reading “Uhura to Proctor…”

J0030…

Topics: Astronomy, Astrophysics, NASA, Neutron Stars, Pulsars NASA’s NICER instrument reveals that neutron stars are not as simple as we thought. Pulsars are the lighthouses of the universe. These tiny, compact objects are neutron stars — the remnants of once-massive stars — that spin rapidly, beaming radiation into space. Now, for the first time, astronomersContinue reading “J0030…”

ISAAC…

Topics: International Space Station, NASA, Space Exploration, Spaceflight In April 2021, Bumble, one of the free-flying Astrobee robots aboard the International Space Station, was put to the test to investigate a simulated anomaly. In the simulation, the station’s life support systems detected a high concentration of carbon dioxide. A similar situation, in reality, could be very dangerousContinue reading “ISAAC…”

A Voyage In Her Lifetime…

Topics: International Space Station, Interstellar, NASA, Space Exploration, Spaceflight, Star Trek Light Sails were first mentioned in the year 1610 in a letter by astronomer Johannes Kepler to his friend, Galileo Galilei. “With ships or sails built for heavenly winds, some will venture into that great vastness.” Avery Brooks in his character of Benjamin SiskoContinue reading “A Voyage In Her Lifetime…”

Ganymede…

Topics: Astronomy, Astrophysics, NASA, Planetary Science, Space Exploration Ganymede, get ready for your close-up. No probe has gotten a good view of Jupiter’s largest moon since 2000, when NASA’s Galileo spacecraft swung past the strange world, which is the largest moon in the whole solar system. But on Monday (June 7),  at 1:35 p.m. EDT (1735 GMT),Continue reading “Ganymede…”

Sun Quake…

Topics: Astronomy, Astrophysics, ESA, Heliophysics, NASA For new Sun-watching spacecraft, the first solar eruption is always special. On February 12, 2021, a little more than a year from its launch, the European Space Agency and NASA’s Solar Orbiter caught sight of this coronal mass ejection, or CME. This view is from the mission’s SoloHI instrument —Continue reading “Sun Quake…”
