Context:

NASA has invited applications for astronauts under its next Lunar exploration program – Artemis.

About the Artemis(Acceleration, Reconnection, Turbulence, and Electrodynamics of the Moon's interaction with the Sun) Mission

  • It is the next exploration program of NASA which envisages landing of the first Woman and the next Man on moon by 2024.
  • Artemis is a three staged mission with the first two missions testing deep space exploration systems of the moon.

Artemis I mission

An uncrewed flight to test the SLS(Space Launch System) and Orion spacecraft together

Artemis II mission

The first SLS and Orion test flight with crew

 

Artemis III mission

NASA will land astronauts on the Moon by 2024 on the and about once a year thereafter.

  • ARTEMIS mission is derived from two erstwhile probes P1 and P2.
    • P1 and P2 were originally members of another successful mission THEMIS in Earth orbit .
    • The objective of THEMIS was to study Earth’s aurora.

Objectives:

  1. To study the state of the rocky Moon in the absence of the magnetic field when it is hit by Sun’s radiation.
  2. Scientists are also looking up to explore the Earth-moon Lagrange points, the solar wind, the Moon’s plasma wake and how the Earth’s magnetotail and the moon’s own weak magnetism interact with the solar wind.
  3. To explore water and other critical resources which are needed for long-term exploration.
  4. The mission also looks forward to demonstrating new technologies, capabilities and business approaches that will ultimately be needed for the future exploration of Mars.

Details of the Mission

  • The Space launch System, a powerful new rocket will be used to send astronauts aboard the Orion Spacecraft to lunar orbit.
  • The astronauts will be protected with newly designed spacesuits, named as Exploration Extravehicular Mobility Unit, or xEMU.

Aurora Lights

  • The bright dancing lights of the aurora are actually collisions between electrically charged particles from the sun that enter the earth's atmosphere. 
  • The lights are seen above the magnetic poles of the northern and southern hemispheres. They are known as 'Aurora borealis' in the north and 'Aurora australis' in the south.
  • Auroral displays appear in many colours although pale green and pink are the most common.
