• Scientists propose Ceres sample return mission

  Laurel KornfeldSeptember 14th, 2022

  Planetary scientists have recommended NASA send a sample return mission to Ceres, the only dwarf planet located in the asteroid belt between Mars and Jupiter.

• Ceres may have formed in the outer solar system

  Laurel KornfeldApril 3rd, 2022

  Ceres is located in the asteroid belt, but its makeup and large water content suggest it formed in the outer solar system where other dwarf planets orbit.

• Remnants of ancient subsurface ocean observed on Ceres

  Laurel KornfeldOctober 5th, 2020

  The bright spots in Ceres’s Occator Crater, which mystified scientists when first observed by the Dawn spacecraft in 2015, indicate the dwarf planet may harbor remnants of what was once a global subsurface ocean.

• Ceres’ surface found to contain building blocks for life

  Laurel KornfeldDecember 14th, 2018

  The surface of the dwarf planet Ceres holds high levels of organic material, according to a new study of images returned by NASA's Dawn spacecraft. This provides a tantalizing glimpse into the possibility of life throughout our solar system.

• A spaceflight era closes with end of Dawn and Kepler missions

  Laurel KornfeldNovember 3rd, 2018

  The Kepler and Dawn spacecraft both ran out of fuel, marking the end of an era that transformed our understanding of both our solar system and others.

• Dawn’s voyage of discovery comes to a close

  Jason RhianNovember 1st, 2018

  After 11 years and 4.3 billion miles, NASA's Dawn mission has come to an end. How has the spacecraft revolutionized our understanding of the solar system and space hardware?

• Study finds Ceres has history of cryovolcanism

  Laurel KornfeldSeptember 18th, 2018

  A study of surface features on Ceres as revealed by NASA's Dawn spacecraft indicates the dwarf planet experienced cryovolcanism in its past, with individual ice volcanoes having spewed large amounts of material onto the dwarf planet's surface.

• Dawn mission approaches end as spacecraft runs out of fuel

  Laurel KornfeldSeptember 10th, 2018

  NASA's Dawn mission, after 11 years is drawing to a close, but during the years it has explored worlds and forever altered our understanding of the solar system.

• Dawn spacecraft captures new images of Ceres’ Occator Crater

  Jason RhianJuly 4th, 2018

  NASA's Dawn spacecraft has entered into its final planned orbital position from which it will study the dwarf planet Ceres, the lowest the probe has descended to the tiny world since it arrived in orbit on March 6, 2015.

• Dawn will enter lowest ever orbit around Ceres

  Laurel KornfeldJune 2nd, 2018

  NASA's Dawn spacecraft has begun maneuvers that should bring it to its lowest and final orbit around the dwarf planet Ceres.

• Dawn observations indicate Ceres is geologically active

  Laurel KornfeldMarch 17th, 2018

  NASA's Dawn spacecraft, which has been orbiting Ceres for three years, has observed changes on the dwarf planet's surface indicating it is a dynamic, geologically active world. Two separate studies published in the journal Science Advances discuss these changes with one centering on the changing amounts of water ice and the other discussing the formation and distribution of carbonates.

• Bright spots on Ceres indicate geologic activity

  Jim SharkeyDecember 16th, 2017

  Since NASA's Dawn spacecraft arrived at Ceres in March 2015, both scientists and the general public have been able to see the hundreds of bright spots on the dwarf planet's surface. Dawn mission scientists reported their most recent research about these bright areas at the American Geophysical Union meeting in New Orleans, Louisiana, on Tuesday, Dec. 12, 2017. The team's findings indicate that Ceres is an active, evolving world.

• Ancient interior activity likely formed features on Ceres’ surface

  Laurel KornfeldNovember 15th, 2017

  A new analysis of surface features on Ceres sent back by NASA's Dawn spacecraft indicates that at least some of those features were created by the ancient movement of materials in the dwarf planet's interior.

• NASA gives Dawn mission second extension

  Laurel KornfeldOctober 22nd, 2017

  NASA's Dawn spacecraft, which has been orbiting Ceres since March 2015, has just been given a second extension, which will be used to bring the probe into the closest orbit yet around the dwarf planet.

• NASA’s Dawn spacecraft experiences reaction wheel malfunction

  Jim SharkeyApril 28th, 2017

  During preparations for observing Ceres' Occator Crater, NASA's Dawn spacecraft's remaining reaction wheels stopped functioning. The probe controls its orientation in space by changing the speed these gyroscope-like devices spin.
