Lucy Spacecraft’s Second Slingshot of Earth - YouTube - NASA Goddard - solar system studies

Lucy is a NASA space probe that is on a twelve year mission to eight different asteroids.It is slated to visit two Main Belt Asteroids,as well as six Trojan asteroids that share Jupiter's orbit around the Sun.All encounters will be flyby encounters.The mission is named for the Lucy hominim fossils,because the study of the Trojans could reveal the fossils of planetary formation:materials that clumped together in the early history of the solar system to form planets and other bodies.*Lucy's instruments are:Long Range Reconaissance Imager (L'LORRI);Optical and Near-Infrared Imaging Spectrometer (L'RALPH) and Thermal Infrared Spectrometer( L'TES).Principal Investigator is Harold F. Levison of the Southwest Research Institute in Boulder,Colorado.Simone Marchi of SRI is the Mission's Deputy Principal Investigator.NASA Goddard Spaceflight Center in Greenbelt,Maryland executes the mission under the direction of the Planetary Mission Program Office at NASA Marshall Space Flight Center.*The Lucy spacecraft was launched from what is now Cape Canaveral Space Force Station's Space Launch Complex-41 on a United Launch Alliance Atlas V 401 rocket on 16 October 2021.*United Launch Alliance is a joint venture of Boeing Space and Defense and Lockheed Martin Space.Boeing (BA),Lockheed Martin (LMT)

Fixing Voyager: How NASA Restored Communications with Voyager 1 from Across the Solar System - YouTube - solar system studies/interstellar studies

with Gregory Smith,communications and education directorate,NASA/JPL;Calla Colfield,media relations specialist,NASA/JPL;Kareem Badaruddin,Voyager mission manager;and Dr.Linda Spilker,Voyager project scientist*Both Voyager spacecraft are now in interstellar space,doing groundbreaking research on the interstellar medium.*The software engineering was needed to correct a hardware failure due to a part failure or cosmic radiation.There are five instruments on each Voyager that are still working:1.the magnetometer,measuring the intensity and direction of the magnetic field;2.the plasma wave detector,that actually measures the radio signals in space;3.the low energy charged particle instrument,measuring low energy cosmic rays,protons,electrons and molecules-it actually can step and measure in eight different directions;4.the plasma spectrometer,which measures the composition,temperature and density of the plasma in the interstellar medium;and 5.the cosmic ray spectrometer that measures the higher energy cosmic rays,the cosmic rays and particles coming from supernova explosions.

Mission to Psyche: One Year Into the Spacecraft’s Journey to a Metal-Rich Asteroid - YouTube - solar system studies

All of Psyche's instruments are working:the magnetometer;the gamma ray spectrometer;the neutron spectrometer;the imagers;and the gravity experiment.The Hall thruster engine will be the first such engine used outside the Earth/Moon system.The Hall thruster is an ion thruster engine.An ion is an atom or molecule with an electric charge due to the loss or gain of one or more electrons.Hall thrusters use a magnetic field to limit their electrons' axial motion and then use them to ionize propellant.The most common propellants used are Xenon and Krypton.Psyche could reveal some of the early history of the solar system.Some asteroids are believed to be planetesimals,chunks of material left over from the planet formation process.The definition of a planetesimal is a minute planet,a body that could or did come together with many others under gravitation to form a planet. *Credit:NASA/Jet Propulsion Laboratory-California Institute of Technology/ASU

🌎 LIVE Asteroid Apophis Near Earth Countdown ☄️ NASA Eyes - YouTube - WorldCam - solar system studies

It all began late one night in June 2004 with a small dot swimming into view through the optics of NSF Kitt Peak National Observatory in the Arizona mountains.Astronomer Fabrizio Bernardi and two colleagues flagged the dot as a possible newly discovered asteroid and confirmed its space rock status in short order.9942 Apophis was intriguing but unremarkble-an object the width of a few hundred meters (now estimated at 340 m/1000 ft across) about 770 million km/478,455,818 mi from Earth.Calculations in recent years have proven the asteroid will safely glide past Earth in 2029 and 2036.In 2029,9942 Apophis should pass Earth at a nominal distance of 31,000,000 km/19,662,000 mi from Earth.*According to NASA,asteroids are small space rocks that orbit the Sun.They are remanants from the early formation of the solar system.They are classified as C-type (carbonaceous);M-type (metallic);or S-type (silicaceous).Asteroids are found primarily between the orbits of Mars and Jupiter in the main asteroid belt.They are rocky bodies with no atmosphere.*Notes by WorldCam and edited and augmented by Andrew Taylor

Mysteries of the Moon | The Moon | BBC Earth Science - YouTube - planetary science

Dr.Gary Lofgren is a senior planetary scientest and Lunar Curator at NASA,where he oversees the preparation of lunar material for distributions for scientests to study;for museums to display;and for educational purposes.He has been a research scientest and principal investigator in the NASA Cosmochemistry Program since 1968.He trained Apollo astronauts how to do geology on the Moon.Perhaps the Artemis Missions will help to solve the mysteries of the Moon.

A journey to Proxima Centauri and its planet - YouTube - ESO - astrophysics

This video (silent) shows an artist's impression of a trip from Earth to Proxima b,the closest planet to our Solar System.As we leave our Solar System,we see the familiar constellation figures,including the Southern Cross (Crux) and the bright stars Alpha and Beta Centauri.We gradually close on a faint red star,Beta Centauri,the closest star to Earth and the faintest component of a triple star system.The final part shows the planet Proxima b,the closest exoplanet to our Solar System. ESO edited by Andrew Taylor Credit:ESO,/L. Calcada/Nick Risinger (sky survey.org) Located in Atacama,Chile,the ESO is supported by a consortium of EU member states.

NASA's building a solar sail to propel space exploration - YouTube - Space.com

It's the early days of solar sail technology,which has been mentioned as a way to reach another star within a human lifetime.NASA's vision is to send solar sails to destinations within our solar system.
