This Week @NASA: Critical Preflight Test for Artemis I, DART Planetary Defense, New Webb Images

A critical preflight test for Artemis I …

The first trip to space for a NASA astronaut …

And new Webb Space Telescope images of neighbors in our solar system … a few of the stories to tell you about – This Week at NASA!

A Critical Preflight Artemis I Demonstration Test

On September 21, teams at NASA’s Kennedy Space Center conducted a cryogenic demonstration test with the Space Launch System, or SLS rocket for NASA’s upcoming uncrewed Artemis I flight test around the Moon. The demonstration test was designed to allow teams to confirm the repair of a hydrogen leak that cropped up during a previous launch attempt in early September, evaluate updated procedures for loading the rocket with propellant, and conduct additional evaluations. Keep up with the latest Artemis I updates on NASA’s Artemis blog.

NASA Astronaut Frank Rubio Launches to the Space Station

Also on September 21, NASA astronaut Frank Rubio launched to the International Space Station (ISS) from Kazakhstan with two other members of the station’s Expedition 68 crew. Later that same day, they docked to the station’s Rassvet module and were welcomed aboard by the Expedition 67 crew, including NASA’s Bob Hines, Kjell Lindgren, and Jessica Watkins. This is Rubio’s first spaceflight.

Webb Image Captures Clearest View of Neptune’s Rings in Decades

NASA’s Webb Space Telescope’s first image of Neptune includes the clearest view of Neptune’s rings since the images Voyager 2 captured during its 1989 flyby of the distant planet. Webb also captured seven of Neptune’s 14 known moons including Triton, which orbits Neptune in an unusual retrograde, or backward direction. Additional studies by Webb of both Triton and Neptune are planned in the coming year.

Webb’s First Observations of The Red Planet

The Webb Space Telescope recently used its infrared capability to capture its first images and spectra of Mars. Images of the planet’s eastern hemisphere captured by Webb’s Near-Infrared Camera show surface features, such as craters and dust layers, as well as thermal emission, or light given off by the planet as it loses heat. Meanwhile, data from the telescope’s first near-infrared spectrum of Mars could give astronomers additional details about the planet’s surface and about its atmosphere.

InSight Detects an Impact for the First Time: These craters were formed by a September 5, 2021, meteoroid impact on Mars, the first to be detected by NASA’s InSight. Taken by NASA’s Mars Reconnaissance Orbiter, this enhanced-color image highlights the dust and soil disturbed by the impact in blue in order to make details more visible to the human eye.

InSight “Hears” Its First Meteoroid Impacts on Mars

That strange noise is what a space rock crashing into Mars sounds like to NASA’s InSight lander. InSight detected seismic waves from four meteoroid impacts on the Red Planet in 2020 and 2021. This includes an impact on September 5, 2021, that made these craters (see image above). Not only are these the first impacts detected by InSight’s seismometer since the spacecraft landed in 2018, but they also mark the first time seismic and acoustic waves from an impact have been detected on Mars.

DART was approximately 16 million miles (26 million km) from Earth when the image was taken, with Jupiter approximately 435 million miles (700 million km) away from the spacecraft.

DART Uses Jupiter and Europa to Test Navigation System

NASA’s DART spacecraft is on track to intentionally crash into the asteroid moonlet Dimorphos on September 26. The views in this composite image of the Jupiter system were captured during recent testing with the spacecraft’s imager and guidance systems to target and track Jupiter’s moon Europa as it emerged from behind the planet, similar to how Dimorphos will visually separate from Didymos, the larger asteroid it orbits. DART, the world’s first planetary defense test mission, is designed to deflect and alter the course of an asteroid should one ever be discovered that is a threat to Earth. Neither Dimorphos nor Didymos is a threat to Earth.

That’s what’s up this week @NASA …

  • Mathematics is the language in which human beings write the universe.The nature of space-time motion is the interaction of topological vortex fields.If there are no physical environment with dark matter and dark energy topological vortexes, there can be neither all kinds of celestial bodies and microscopic particles nor the interaction of them.That's all!
