Sonification

• Non-speech audio to convey information or perceptualize data

Hayabusa-2 mission

• was launched in December 2014
• Japan Aerospace Exploration Agency’s (JAXA) 
• To study the asteroid Ryugu
• Ryugu is also classified as potentially hazardous asteroids (PHAs). and was discovered in 1999.
• The Hayabusa mission-1 brought samples from the asteroid Itokawa in 2010.

Asteroids

• Asteroids are rocky objects that orbit the Sun, much smaller than planets
• called minor planets

NASA

• NASA’s OSIRIS-REX mission collected samples from the asteroid Bennu in October 2020, which will be brought to Earth in 2023.

About

• second Lagrange point (L2)
• At L2, the gravitational pulls of the sun and the Earth keep Webb’s motion around the sun in synchronization with Earth’s.
• Infrared light

Aim

• to understand the Universe and our origins

Artemis(goddess of the moon) Mission: NASA

• NASA’s Artemis mission aims to put humans back on the moon
• Space Launch System (SLS), which will carry all the spacecraft part of Artemis missions.
• next generation of lunar exploration.

CAPSTONE

• Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment
• It will study a specific orbit where NASA plans to build a small space station for astronauts to stop at before and after going to the moon’s surface.
• about the size of a microwave oven
• Not Launched by Space-X or NASA

Halo orbit

• The orbits are those influenced by the gravity of two bodies
