Ryugu Impact Crater Data Analysis Illuminates Complicated Geological History

Figure 1: Size and location of craters on Ryugu (Figure from the Journal paper): The craters are numbered in order of size.

KOBE, Japan (Kobe University PR) — Analysis of the impact craters on Ryugu using the spacecraft Hayabusa 2’s remote sensing image data has illuminated the geological history of the Near-Earth asteroid.

A research group led by Assistant Professor Naoyuki Hirata of the Department of Planetology at Kobe University’s Graduate School of Science revealed 77 craters on Ryugu. Through analyzing the location patterns and characteristics of the craters, they determined that the asteroid’s eastern and western hemispheres were formed at different periods of time.

Germany Invests 3.3 Billion Euros in European Space Exploration, Becomes ESA’s Largest Contributor

  • Three years after the last ESA Council Meeting at Ministerial Level, held in Lucerne, Switzerland, government representatives from the 22 Member States met in Seville, Spain, on 27 and 28 November 2019 and committed a total of almost 14.4 billion euro [$15.87 billion] for space programmes over the next few years.
  • Germany is contributing 3.3 billion euro [$3.6 billion] to ESA programmes focusing on Earth observation, telecommunications, technological advancement and commercialisation / NewSpace.
  • At 22.9 percent, Germany is now ESA’s largest contributor, followed by France (18.5 percent, 2.66 billion euro), Italy (15.9 percent, 2.28 billion euro) and the United Kingdom (11.5 percent, 1.65 billion euro).
  • The ESA Council Meeting at Ministerial Level is the highest political decision-making body, and it defines the content and financial framework for ESA’s space programmes every two to three years.

Ministers Approve ESA’s Hera Asteroid Mission

SEVILLE, Spain (ESA PR) — Europe’s space ministers gathered at Space19+ in Seville, Spain in November 2019 have approved ESA’s Hera asteroid mission for construction and launch, as part of the Agency’s broader planetary defence initiatives that aim to protect European and world citizens.

Hera will be humanity’s first-ever spacecraft to visit a double asteroid, the Didymos binary system. First, NASA will crash its DART spacecraft into the smaller asteroid – known as Didymoon – before ESA’s Hera comes in to map the resulting impact crater and measure the asteroid’s mass.

Hera will carry two CubeSats on board, which will be able to fly much closer to the asteroid’s surface, carrying out crucial scientific studies, before touching down. Hera’s up-close observations will turn asteroid deflection into a well-understood planetary defence technique.

Italy Boosts Contribution to ESA Budget

SEVILLE, Spain (ASI PR) — In Seville, Spain, the institutional representatives and heads of the countries that make up the European Space Agency (ESA) have set the course towards new spatial horizons in the coming years. The share of the Italian contribution rises, while Samantha Cristoforetti will return to orbit.

An increase of almost one billion euros [$1.1 billion] compared to the previous Ministerial is what the Italian delegation to the ESA Ministerial Council 2019 has destined as a contribution of our country to the budget of the ESA for the next three to four years.

Ministers approved funding lunar Gateway, space station operations until 2030, Mars Sample Return and Hera asteroid missions

SEVILLE, Spain (ESA PR) — ESA’s Council at Ministerial Level, Space19+, has concluded in Seville, Spain, with the endorsement of the most ambitious plan to date for the future of ESA and the whole European space sector. The meeting brought together ministers with responsibility for space activities in Europe, along with Canada and observers from the EU.

The Member States were asked to approve a comprehensive set of programmes to secure Europe’s independent access to and use of space in the 2020s, boost Europe’s growing space economy, and make breakthrough discoveries about Earth, our Solar System and the Universe beyond, all the while making the responsible choice to strengthen the efforts we are making to secure and protect our planet.

First Detection of Sugars in Meteorites Gives Clues to Origin of Life

GREENBELT, Md. (NASA PR) — An international team has found sugars essential to life in meteorites. The new discovery adds to the growing list of biologically important compounds that have been found in meteorites, supporting the hypothesis that chemical reactions in asteroids – the parent bodies of many meteorites – can make some of life’s ingredients. If correct, meteorite bombardment on ancient Earth may have assisted the origin of life with a supply of life’s building blocks.

LITTLETON, Colo. (NASA PR — NASA’s Lucy mission successfully completed its Critical Design Review on Oct. 18. 

During this review, Lucy team members presented the completed mission design, demonstrating that the team has met all the technical challenges of the mission and is ready to begin building hardware. After the review completion, NASA’s independent review board provided a green light for proceeding into the fabrication/manufacturing stage of the mission.

NASA announced on Monday that it is planning to spend $500 to $600 million to develop the NEO Surveillance Mission that would begin hunting for large asteroids and comets that could strike Earth.

Thomas Zurbuchen, associate administrator for the Science Mission Directorate, made the announcement during a meeting of the Planetary Science Advisory Committee held in Washington, D.C. NASA’s Jet Propulsion Laboratory (JPL) would lead the project, which would launch around 2025.

Two Asteroids to Safely Fly by Earth

WASHINGTON, DC (NASA PR) — Two relatively medium-sized asteroids will fly safely past Earth overnight Sept. 13-14 (Eastern U.S. time). NASA is tracking the objects, but orbit calculations ruled out any chance that the objects could pose a threat to our planet.

ROME (ESA PR) — Asteroid researchers and spacecraft engineers from the US, Europe and around the world will gather in Rome next week to discuss the latest progress in their common goal: an ambitious double-spacecraft mission to deflect an asteroid in space, to prove the technique as a viable method of planetary defence.

This combined mission is known as the Asteroid Impact Deflection Assessment, or AIDA for short. Its purpose is to deflect the orbit of the smaller body of the double Didymos asteroids between Earth and Mars through an impact by one spacecraft. Then a second spacecraft will survey the crash site and gather the maximum possible data on the effect of this collision.
