PASADENA, Calif. (NASA PR) — The December 2018 close approach by the large, near-Earth asteroid 2003 SD220 has provided astronomers an outstanding opportunity to obtain detailed radar images of the surface and shape of the object and to improve the understanding of its orbit.
The asteroid will fly safely past Earth on Saturday, Dec. 22, at a distance of about 1.8 million miles (2.9 million kilometers). This will be the asteroid’s closest approach in more than 400 years and the closest until 2070, when the asteroid will safely approach Earth slightly closer.
WASHINGTON (NASA PR) — NASA welcomed a new administrator, Jim Bridenstine, deputy administrator, Jim Morhard, and chief financial officer, Jeff DeWit, in 2018. Their focus is on firmly establishing the groundwork to send Americans back to the Moon sustainably, with plans to use the agency’s lunar experience to prepare to send astronauts to Mars.
GREENBELT, Md. (NASA PR) — Recently analyzed data from NASA’s Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) mission has revealed water locked inside the clays that make up its scientific target, the asteroid Bennu.
GREENBELT, Md. (NASA PR) — On Dec. 3, after traveling billions of kilometers from Earth, NASA’s OSIRIS-REx spacecraft reached its target, Bennu, and kicked off a nearly two-year, up-close investigation of the asteroid. It will inspect nearly every square inch of this ancient clump of rubble left over from the formation of our solar system. Ultimately, the spacecraft will pick up a sample of pebbles and dust from Bennu’s surface and deliver it to Earth in 2023.
Forbes takes a critical look at cryptocurrency/block chain guru Joe Lubin, whose ConsenSys company purchased asteroid mining company Planetary Resources. (Although given the headline, critical seems polite: Cryptopia In Crisis: Joe Lubin’s Ethereum Experiment Is A Mess. How Long Will He Prop It Up?)
So, how does asteroid mining fit into Lubin’s master plan?
Lubin insists ConsenSys is getting more selective in picking projects. But old habits die hard. In October it bought a nine-year-old asteroid-mining company called Planetary Resources. “We see it as a group of amazingly capable people who are interested in exploring how blockchain could ramify on space operations,” Lubin says abstrusely.
WASHINGTON (NASA PR) — NASA researchers will present new findings on a wide range of Earth and space science topics at the annual meeting of the American Geophysical Union (AGU), Dec. 10-14 in Washington. NASA-related briefings will stream live on the agency’s website.
Briefing topics include: the latest findings from the Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-Rex) mission to asteroid Bennu and the new Ice, Cloud and land Elevation Satellite-2 (ICESat-2) Earth-observing mission; the lingering impact of Hurricane Maria on Puerto Rico; and an update on Voyager 2 at the edge of the solar system.
Agency scientists, and their colleagues who use NASA research capabilities, also will present noteworthy findings during scientific sessions that are open to registered media.
Details on NASA presentations will be updated online throughout the week. For a complete and up-to-date schedule of briefings and media participation information, visit:
LITTLETON, Colo. (NASA PR) — NASA’s Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) spacecraft is scheduled to rendezvous with its targeted asteroid, Bennu, on Monday, Dec. 3 at approximately noon EST.
NASA will air a live event from 11:45 a.m. to 12:15 p.m. EST to highlight the arrival of the agency’s first asteroid sample return mission. The program will originate from OSIRIS-REx’s mission control at the Lockheed Martin Space facility in Littleton, Colorado, and will air on NASA Television, Facebook Live, Ustream, YouTube and the agency’s website. NASA TV also will air an arrival preview program starting at 11:15 a.m. EST.
OSIRIS-REx launched in September 2016 and has been slowly approaching Bennu. The spacecraft will spend almost a year surveying the asteroid with five scientific instruments with the goal of selecting a location that is safe and scientifically interesting to collect the sample. OSIRIS-REx will return the sample to Earth in September 2023.
Participants in the arrival coverage event include:
Michelle Thaller, moderator, NASA’s Goddard Space Flight Center, Greenbelt, Md
Rich Burns, OSIRIS-REx project manager, NASA’s Goddard Space Flight Center, Greenbelt, Md
Heather Enos, OSIRIS-REx deputy principal investigator, University of Arizona, Tucson

A little over 4 billion years ago, the planets in our solar system coexisted with vast numbers of small rocky or icy objects orbiting the Sun. These were the last remnants of the planetesimals – the primitive building blocks that formed the planets. Most of these leftover objects were then lost, as shifts in the orbits of the giant planets scattered them to the distant outer reaches of the solar system or beyond. But some were captured in two less-distant regions, near points where the gravitational influence of Jupiter and the Sun balance, and have remained trapped there, mostly untouched, for billions of years.
DENVER, Nov. 16, 2018 (Lockheed Martin PR) — TAGSAM, or Touch-and-Go Sample Acquisition Mechanism, completed a successful practice deployment in space on Nov. 14—an important milestone in the OSIRIS-REx mission to the asteroid Bennu. TAGSAM is the first-of-its-kind robotic arm and sampling head invented by Lockheed Martin.
Luxembourg Economy Minister Etienne Schneider has disclosed to Parliament that the nation lost €12 million ($13.7 million) investing in the asteroid mining company Planetary Resources, the Luxembourg Times reports.
In October, Luxembourg sold its stake in the company, which was acquired by the block chain management firm ConsenSYS.
The SNCI set up the SAAM Luxembourg, a company created with €13.75 million [$15.7 million], of which €12 million [$13.7 million] was directly invested in Planetary Resources for the 10% stake in its shares.
“This decision to sell results, among other things, from an analysis of the particular American legal context and prudent management which intends to limit the potential exposures of SAAM Luxembourg, or even of SNCI as sole shareholder of SAAM Luxembourg,” Schneider explained.
“The realised capital loss corresponds roughly to the value adjustment (of 100% of the sums invested in Planetary Resources) in the accounts in SAAM Luxembourg’s 2017 annual results,” he added.
COPENHAGEN (University of Copenhagen PR) — An international team lead by researchers from the Centre for GeoGenetics at the Natural History Museum of Denmark, University of Copenhagen have discovered a 31-km wide meteorite impact crater buried beneath the ice-sheet in the northern Greenland. This is the first time that a crater of any size has been found under one of Earth’s continental ice sheets. The researchers worked for last three years to verify their discovery, initially made in the 2015. The research is described in a new study just published in the internationally recognized journal Science Advances.
The entire history of human existence is a tiny blip in our solar system’s 4.5-billion-year history. No one was around to see planets forming and undergoing dramatic changes before settling in their present configuration. In order to understand what came before us — before life on Earth and before Earth itself — scientists need to hunt for clues to that mysterious distant past.
NASA will host a live Science Chat at 2 p.m. EST Wednesday, Nov. 7, to discuss upcoming encounters of two of the agency’s planetary missions – the arrival of the Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) at the asteroid Bennu, on Dec. 3, and New Horizons’ historic flyby of Kuiper Belt object 2014 MU69, on Jan. 1, 2019.
Topics will include the critical clues these objects hold to the formation of the solar system, complementary mission science goals and much more.

Media may submit questions before and during the event by emailing JoAnna Wendel at email@example.com. The public may ask questions on Twitter by using the hashtag #askNASA or by leaving a comment on the livestream of the event on the NASA Solar System page.
The OSIRIS-REx spacecraft will initiate an intricate dance with Bennu, mapping and studying it in preparation for sample collection in July 2020. OSIRIS-REx will deliver the sample to Earth in September 2023.
New Horizons will fly by its target, nicknamed Ultima Thule, approximately four billion miles from Earth – the farthest space probe flyby in history. This encounter complements the discoveries still coming from the mission’s July 2015 exploration of the Pluto system. However, this time, the spacecraft will come three times closer to Ultima than it did to Pluto.
