Venus Parker Solar Probe toward record-setting flights around the Sun
Laurel MD (SPX) Aug 24, 2023 NASA's Parker Solar Probe zoomed past Venus on Aug. 21, using the planet's gravity to aim toward a record-setting series of flights around the Sun that start next month. At just before 8:03 a.m. EDT, moving approximately 15 miles (more than 24 kilometers) per second, Parker Solar Probe passed 2,487 miles (4,003 kilometers) above the Venusian surface as it curved around the planet toward the inner solar system. The mission operations team at the Johns Hopkins Applied Physics Laboratory (APL) in Lau ... read more |

Course correction keeps Parker Solar Probe on track for Venus flybyLaurel MD (SPX) Aug 11, 2023 NASA's Parker Solar Probe executed a short maneuver on Aug. 3, 2023, that kept the spacecraft on track to hit the aim point for the mission's sixth Venus flyby on Monday, Aug. 21, 2023. Operat ... more 
What keeps Venus looking so young? A powerful jolt early on, perhapsNew Haven CT (SPX) Jul 31, 2023 Researchers at Yale and the Southwest Research Institute may have discovered the secret to Venus's youthful appearance: a high-energy, rejuvenating boost it received in its earliest years. For decad ... more 
SwRI-led team finds ancient, high-energy impacts could have fueled Venus volcanismSan Antonio TX (SPX) Jul 21, 2023 A Southwest Research Institute-led team has modeled the early impact history of Venus to explain how Earth's sister planet has maintained a youthful surface despite lacking plate tectonics. The team ... more 
Venus atmosphere in 3D prepares future observations of rocky exoplanetsLisbon, Portugal (SPX) Jun 15, 2023 The Venus atmosphere may be used as a natural laboratory to understand the evolution of Earth-like planets, according to a study led by the Instituto de Astrofisica e Ciencias do Espaco (IA) Venus ... more |

BepiColombo and Solar Orbiter compare notes at VenusAmsterdam, Netherlands (SPX) Jan 27, 2023 The convergence of two spacecraft at Venus in August 2021 has given a unique insight into how the planet is able to retain its thick atmosphere without the protection of a global magnetic field. ... more
Massive Volcanism May Have Altered Ancient Venus' ClimateGreenbelt MD (SPX) Nov 18, 2022 Volcanic activity lasting hundreds to thousands of centuries and erupting massive amounts of material may have helped transform Venus from a temperate and wet world to the acidic hothouse it is toda ... more 
NASA instrument to measure temperature, pressure, and wind on VenusGreenbelt MD (SPX) Oct 21, 2022 The VASI (Venus Atmospheric Structure Investigation) instrument aboard NASA's Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging, or DAVINCI, mission to Venus, together with ... more 
JPL's Venus Aerial Robotic Balloon Prototype Aces Test FlightsPasadena CA (JPL) Oct 11, 2022 A scaled-down version of the aerobot that could one day take to the Venusian skies successfully completed two Nevada test flights, marking a milestone for the project. The intense pressure, he ... more 
Coronal mass ejection hits Solar Orbiter before Venus flybyParis (ESA) Sep 06, 2022 In the early hours of Sunday, 4 September, Solar Orbiter flew by Venus for a gravity-assist manoeuvre that alters the spacecraft's orbit, getting it even closer to the Sun. As if trying to get the o ... more |

New analysis shows how sulfur clouds can form in Venus' atmosphere
Tucson AZ (SPX) Aug 10, 2022 Scientists using sophisticated computational chemistry techniques have identified a new pathway for how sulfur particles can form in the atmosphere of Venus. These results may help to understand the long sought-after identity of the mysterious ultraviolet absorber on Venus. "We know that the atmosphere of Venus has abundant SO2 and sulfuric acid particles. We expect that ultraviolet destruction of SO2 produces sulfur particles. They are built up from atomic S (sulfur) to S2, then S4 and finally S8 ... read more 
Readying spacecraft to surf Venus' atmosphereParis (ESA) Jul 28, 2022 ESA's EnVision mission to Venus will perform optical, spectral and radar mapping of Earth's sister planet. But before getting down to work the van-sized spacecraft needs to 'aerobrake' - lowering it ... more |

NASA's DAVINCI Mission To Take the Plunge Through Massive Atmosphere of VenusGreenbelt MD (SPX) Jun 03, 2022 In a recently published paper, NASA scientists and engineers give new details about the agency's Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging (DAVINCI) mission, which w ... more 
Student-Built, Dime-Sized Instrument Is Venus-bound on NASA's DAVINCIGreenbelt MD (SPX) Jun 03, 2022 Venus Oxygen Fugacity (VfOx) is a small, button-sized sensor aboard NASA's DAVINCI mission to Venus' atmosphere that will be designed, fabricated, tested, operated, ... more 
Why Venus rotates, slowly, despite sun's powerful gripRiverside CA (SPX) Apr 22, 2022 If not for the soupy, fast-moving atmosphere on Venus, Earth's sister planet would likely not rotate. Instead, Venus would be locked in place, always facing the sun the way the same side of the moon ... more 
Aerial antenna for Venus mission testParis (ESA) Mar 07, 2022 How can you accurately test a space antenna down here on Earth when it has been scaled up to penetrate the subterranean depths of another planet? This was the question faced by SENER in Spain, curre ... more 
The secret of Venus may be hidden in the heat of the nightLisbon, Portugal (SPX) Feb 23, 2022 Despite being close to Earth and having nearly the same size, Venus is another world. Underneath its thick mantle of acid sulfuric clouds, at the surface 460 degrees Celsius are the rule. This tempe ... more |
