Nasa's Dawn spacecraft is about to make history, nears historic arrival at dwarf planet Ceres

NASA spacecraft is about to make history on March 6, 2015 as the spacecraft will become the first ever to visit a dwarf planet. in addition it will also be the first spacecraft to visit Ceres.

See what we reported about Dawn when it was on its way to Ceres.

"Dawn is about to make history," said Robert Mase, project manager for the Dawn mission at NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California. "Our team is ready and eager to find out what Ceres has in store for us."

Mystery of white spot!

As seen In above image this white spot on Ceres has left scientists baffled. The mystery will be unfolded soon as Dawn takes closer shots. Since Jan. 25, Dawn has been delivering the highest-resolution images of Ceres ever captured, and they will continue to improve in quality.

Cnet in one of their report suggests 8 possible explanation for this bright spot -

1) A salt flat
2) Shiny metals
3) exposed ice
4) water vapour
5) Ice volcanoes
6) Aliens' solar concentrators
7) Genetically engineered colonists from another civilization
8) A spacecraft

Ceres is the most massive body in the asteroid belt, with an average diameter of 590 miles (950 kilometers). Ceres' surface covers about 38 percent of the area of the continental United States.

Dawn has already completed successfull observations of the protoplanet Vesta.

"By studying Vesta and Ceres, we will gain a better understanding of the formation of our solar system, especially the terrestrial planets and most importantly the Earth," said Raymond. "These bodies are samples of the building blocks that have formed Venus, Earth and Mars. Vesta-like bodies are believed to have contributed heavily to the core of our planet, and Ceres-like bodies may have provided our water." "We would not be able to orbit and explore these two worlds without ion propulsion,” Mase said. “Dawn capitalizes on this innovative technology to deliver big science on a small budget.”

In addition to the Dawn mission, NASA will launch in 2016 its Origins-Spectral Interpretation-Resource Identification- Security-Regolith Explorer (OSIRIS-REx) spacecraft. This mission will study a large asteroid in unprecedented detail and return samples to Earth.
