NASA's Dawn spacecraft recently discovered some of the best looks researchers have ever seen on the mysterious luminous spots of the planet Ceres.
The NASA / JPL flight team discovered a new orbit around the dwarf planet that would get the probe 22 miles (35 kilometers) from the nearest dive. This allowed the Dawn vessel to have a perfect view of the 92-mile (92 km) Occator crater – the site of the famous light points. The new photos of June 14 and June 22 could finally give researchers a better understanding of the bright spots by providing a more complete look at the Ceres crater floor.
The Occator Crater has been a point of interest for researchers looking to further explore Ceres. In 2015, the Dawn craft discovered that the floor of the camper contained surprisingly bright deposits. Subsequent observations of the probe made it possible to explain that the bright and mysterious sections consisted of sodium carbonate. The researchers explained that these deposits are the largest deposits of carbonates on the outside of the Earth, and that they are potentially larger than those found on Mars.
"The first views of Ceres obtained by Dawn have signaled to us only one blinding bright spot," said Carol Raymond of JPL, Dawn's chief investigator. "Discovering the nature and history of this fascinating dwarf planet during Dawn's long stay in Ceres has been fascinating, and it is particularly fitting that Dawn's latest act provides new data sets to test these theories. "
NASA and the Jet Propolision Laboratory hope that the observations could help answer the key questions that remain about carbonate deposition.
"The acquisition of these spectacular images was one of the biggest challenges of Dawn's extraordinary extraterrestrial expedition, and the results are better than we had hoped," says Marc Rayman, chief engineer and project manager at Dawn. in Pasadena, California, said in a statement. "Dawn is like a master artist, adding rich details to the beauty of another world in her intimate portrait of Ceres."
Launched in September 2007, the Dawn mission costs NASA about $ 467 million. The NASA team simply wanted the spacecraft to study Vesta and Ceres – two objects found between Mars and Jupiter. Why are researchers particularly interested in Vesta and Ceres? It is believed that the two dwarf planets are building blocks of the first era of the solar system. By studying Vesta and Ceres, NASA researchers hope to better understand how our solar system came about.
The Dawn probe began its orbit of Vesta in June 2011 and ended in September 2012. It then settled in Ceres and arrived there in March 2015. Successful arrival from Dawn to Ceres made the spacecraft the first orbit two objects other than the Earth and its moon.
Researchers are particularly fortunate to obtain these insightful images as Dawn's craft runs a lot low on fuel. Dawn is almost out of the hydrazine that powers the propellers of the craft. The end of hydrazine will mean the end of Dawn; the probe will no longer be able to return its instruments to the Earth to communicate or get closer to Ceres to collect information.
