PARIS (ESA PR) — Asteroid 2006 QV89, a small object 20 to 50 metres in diameter, was in the news lately because of a very small, 1-in-7000 chance of impact with Earth on 9 September 2019.

In the first known case of ruling out an asteroid impact through a ‘non-detection’, ESA and the European Southern Observatory have concluded that asteroid 2006 QV89 is not on a collision course this year – and the chance of any future impact is extremely remote.

TOKYO (JAXA PR) — Today (July 11), the Hayabusa2 spacecraft performed a second touchdown on the surface of asteroid Ryugu. The touchdown occurred at 10:06 JST at the on board time and was successful.

From the data sent from Hayabusa2, it has been confirmed that the touchdown sequence, including the discharge of a projectile for sampling, was completed successfully. Hayabusa2 is functioning normally, and thus the second touchdown ended with success.

Below we show images taken before and after the touchdown. As this is a quick bulletin, more detailed information will be given in the future.

TOULOUSE, France (ESA PR) — ESA’s Hera mission for planetary defence, being designed to survey the smallest asteroid ever explored, is really three spacecraft in one. The main mothership will carry two briefcase-sized CubeSats, which will touch down on the target body. A French team has been investigating what might happen at that initial instant of alien contact.

“We’ve customised an existing drop tower and rigged it up with a system of pulleys and counterweights in order to simulate a low gravity environment,” explains researcher Naomi Murdoch of the Institut Supérieur de l’Aéronautique et de l’Espace (ISAE-Supaero), part of the University of Toulouse.

Managing Editor

NASA selected two projects for funding focused on developing in-space welding technologies as part of its recent round of Small Business Innovation Research (SBIR) awards.

The space agency selected Busek Company of Natick, Mass., and Made in Space of Jacksonville, Fla., for phase 1 awards worth up to $125,000 apiece for six months.

“Busek proposes to initiate the development of a semi-autonomous, teleoperated welding robot for joining of external (or internal metallic uninhabited volume at zero pressure) surfaces in space,”according to the proposal summary. “This welding robot will be an adaptation of a versatile Busek developed system called SOUL (Satellite On Umbilical Line) with a suitable weld head attached to it.

Tunguska Revisited: 111-Year-Old Mystery Impact Inspires New, More Optimistic Asteroid Predictions

Trees flattened by the intense shock wave created in the atmosphere as the space rock exploded above Tunguska on June 30, 1908. The photograph was taken by the Soviet Academy of Science 1929 expedition led by Leonid Kulik. 500,000 acres, the size of a large metropolitan city, were flattened. Flattening trees requires an immense shock wave. #WorldAsteroidDay is held every June 30 as a global awareness campaign where people around the world come together to share knowledge about asteroids and learn how to protect our planet.

Every single day, many tons of tiny rocks – smaller than pebbles – hit the Earth’s atmosphere and disintegrate. Between frequent shooting stars we wish on in the night sky and the massive extinction-level asteroids that we hope we never see, there is a middle ground of rocks sized to make it through the atmosphere and do serious damage to a limited area. Now, new research from NASA indicates that the impacts of these mid-size rocks may be less frequent than previously thought.

MOFFETT FIELD, Calif. (NASA PR) — The research revealed that such relatively small but regionally devastating impacts happen on the order of millennia – not centuries, as previously thought. In addition, the new research has pushed forward our knowledge about the complex processes that determine how large rocks from space break up when entering Earth’s atmosphere.

DENVER  (Lockheed Martin PR) — Lockheed Martin (NYSE: LMT) has been selected to design dual small deep space spacecraft to visit near-earth asteroids in a mission called Janus, led by the University of Colorado Boulder.

One of NASA’s Small Innovative Mission for Planetary Exploration (SIMPLEx) finalists, Janus is designed to fly by two binary asteroids, or asteroids orbiting a common center of mass, to image the system using both visible and infrared cameras. These small satellites will launch in 2022 to reach the asteroid system in 2026.

This is a composite of 28 images taken at 7 second intervals starting from 10:58 JST (upper left) to 11:01 (lower right) using the Optical Navigation Camera – Telescopic (ONC-T). The image altitude is about 52m at the start and 108m at the end. The white point in the upper-left center is the target marker. You can see that detailed images have been acquired continuously from the target marker to the edge of the artificial crater, located in the lower-right of the image.

TOKYO (JAXA PR) — Our first touchdown took place this year on February 22. Then as a new challenge for the Hayabusa2 Project, we succeeded in creating an artificial crater using the Small Carry-on Impactor (SCI) on April 5.

The last big operation left at asteroid Ryugu is the collection of subsurface material exposed with the creation of the artificial crater. In order to collect this material, we need a second touchdown for which the project has been steadily preparing. At this point, it has not yet been decided whether or not to go ahead with a second touchdown, but here we will introduce our preparations in the “Approach to the second touchdown”.

New NAS Report Recommends NASA Build Space-Based Infrared Telescopes to Detect Near-Earth Asteroids

WASHINGTON (NAS PR) — The likelihood of a large asteroid hitting Earth in any given year, or even over one’s lifetime, is very small. However, the consequences of such a strike would be great. Detecting near-Earth objects (NEOs), determining their orbits, and estimating their mass is critical knowledge necessary to quantify their destructive potential.

A new report titled, Finding Hazardous Asteroids Using Infrared and Visible Wavelength Telescopes , from the National Academies of Sciences, Engineering, and Medicine analyzes the advantages and disadvantages of telescope capabilities in detecting NEOs and says that space-based infrared NEO survey telescopes are more effective than visible wavelength telescopes, provide diameter information that visible wavelength telescopes cannot provide, and do not cost significantly more than in-space visible wavelength telescopes.

The report also says that if NASA develops a space-based infrared NEO survey telescope, it should also continue to fund both short- and long-term ground-based observations to refine estimates of the orbits and physical properties of NEOs, which helps to assess the risk they might pose to Earth.
