Year milestone 1962

• 
  One of the most unique features of the Gateway is that it can be moved to other orbits around the Moon to conduct more research.
  
• 
  The Gateway will act as an airport, where spacecraft bound for the lunar surface of Mars can refuel or replace parts and resupply things like food and oxygen, allowing astronauts to take multiple trips to the Lunar surface and exploration of new locations across the Moon.
  

• 
  Astronauts will use the Gateway at least once per year and not stay around the year as they do on the International Space Station (ISS).
  
• 
  Compared to the ISS, the Gateway is much smaller (the size of a studio apartment), while the ISS is about the size of a six-bedroom house.
  

Dawn Mission

• 
  Dawn mission was launched by NASAdeploying spacecraft to study the asteroid Vesta and dwarf planet Ceres.
  
• 
  It is the only mission ever to orbit two extraterrestrial targets and will characterize the early solar system and the processes that dominated its formation.
  
• 
  Vesta and Ceres are celestial bodies believed to have accreted early in the history of the solar system.
  
• 
  Dawn orbited giant asteroid Vesta for 14 months from 2011 to 2012, then continued on to Ceres, where it has been in orbit since March 2015.
  
• 
  The spacecraft is likely to run out of a key fuel known as hydrazine which keeps it oriented and in communication with Earth.
  

Ceres and Vesta

• 
  Ceres is the earliest known and smallest of the dwarf planet.
  
• 
  It is also the largest object in the asteroid belt between Mars and Jupiter.
  
• 
  Thus Ceres is both a dwarf planet and an asteroid.
  
• 
  Vesta is the second most massive body in the asteroid belt, surpassed only by Ceres.
  

DART (Double Asteroid Redirection Test)

The DART is a planetary defense-driven test of technologies for preventing an impact of Earth by a hazardous asteroid.
