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.
TOULOUSE, France (Airbus PR) — As the world observes International Asteroid Day – established by the United for global awareness about asteroids – Airbus continues its leadership in a multinational European programme that could help humanity to protect itself from future impact hazards posed by these space objects.
Tassreports that Russia’s state nuclear corporation, Rosatom, is exploring ways to blow up asteroids before they blow us up.
“Our study is only a part of the quest to create an asteroid protection system. The priorities here are detection, classification and high-precision monitoring of a celestial body. After that, a bomb should be designed, which would be safe enough during the launch. A carrier rocket will have to be designed, too,” said Vladimir Rogachev, the deputy head of the laser physics institute at the Russian Federal Nuclear Center (VNIIEF), part of the Rosatom corporation.
“This is an international task of impressive scope. We have something to offer. But there are also things that we need to borrow,” he went on.
“Regretfully, international politics and the current state of international relations necessitate a different format of communications, so we have to wait. But we should not procrastinate: when a dangerous asteroid approaches the Earth, it will be too late,” the researcher added.
Rogachev said that VNIIEF scientists have “baked” an artificial chondrite, the most popular type of asteroids, to study its qualities. According to their calculations, if a 200-meter asteroid approaches the Earth, a rocket should be launched approximately a month before the planned impact, to smash the celestial body into small parts that would burn upon entering the atmosphere.
“Yes, some parts will reach the surface of the planet, but, due to their small size, there will be no apocalypse,” he said. “This technology would be sufficient to destroy an object similar to the Tunguska meteor.”
NASA’s ambitious effort to redirect a small asteroid has run into challenges with its financing, technology and foreign partner that could delay its launch and reduce its scientific return, according to a new assessment by the Government Accountability Office (GAO).
The Double Asteroid Redirection Test (DART) will impact the smaller of the binary near-Earth asteroid Didymos. Scientists will study how the asteroid is deflected to learn how similar systems might be used on potentially hazardous near-Earth objects.
Despite a last minute threat of a veto, President Donald Trump signed an $1.3 trillion omnibus spending bill on Friday that boosts NASA spending by about $1.1 billion to $20.7 billion.
So, with the fiscal year nearly half over, let’s take a closer look at NASA’s FY 2018 budget, which the Administration had tried to cut. The table below lays out the numbers from the omnibus bill, the Administration’s request and the FY 2017 budget.
PASADENA, Calif. (NASA PR) — NASA’s Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) mission has released its third year of survey data, with the spacecraft discovering 97 previously unknown celestial objects in the last year. Of those, 28 were near-Earth objects, 64 were main belt asteroids and five were comets.

In 2005, the Hayabusa spacecraft developed by the Japan Aerospace Exploration Agency (JAXA) landed on Itokawa, a small near-Earth asteroid named after the famous Japanese rocket scientist Hideo Itokawa. The aim of the unmanned mission was to study the asteroid and collect a sample of material to be returned to Earth for analysis. Contrary to scientific predictions that small asteroids are barren nuggets of rock, photographs taken by the Hayabusa spacecraft revealed that the surface of Itokawa is strewn with different sized particles. Even more puzzling was the lateral separation of small and large particles – with large boulders occupying the highlands and small pebbles occupying the lowlands.

The National Near-Earth Object Preparedness Strategy (Strategy) and the forthcoming National Near-Earth Object Preparedness Action Plan (Action Plan) together seek to improve our Nation’s preparedness to address the hazard of near-Earth object (NEO) impacts by enhancing the integration of existing national and international assets and adding important capabilities that are currently lacking. The Strategy and Action Plan build on efforts at the National Aeronautics and Space Administration (NASA) to better detect and characterize the NEO population as well as recent efforts at the Department of Homeland Security (DHS) to prepare for and respond to a NEO impact. Together, they aim to foster a collaborative effort in which the Nation can better understand, prevent, and prepare for the effects of a NEO impact. The Nation must continue to leverage existing networks of expertise and capabilities, both public and private, and pursue targeted enhancements to improve the ability to manage the risks associated with NEOs.
BERLIN, Germany, 14 November 2016 (Press Release) – During a press event today at the Museum für Naturkunde (MfN) (Museum of Natural History) in Berlin, a major campaign was launched to support scientific missions designed to increase our knowledge of asteroids and near Earth objects (NEOs), in particular ESA’s Asteroid Impact Mission.
The campaign, “I Support AIM (www.isupportaim. com) was initiated by the co-founders of Asteroid Day, the global movement to protect the world from dangerous Asteroids, and the Observatoire de la Côte D’Azur, one of the most important research institutions worldwide in the areas of biological and geological evolution and biodiversity.
LUXEMBOURG CITY (Luxembourg Government PR) — The Luxembourg Government forges ahead with the SpaceResources.lu initiative by presenting an overall strategy to be implemented progressively for the exploration and commercial utilization of resources from Near Earth Objects (NEOs), such as asteroids. Amongst the key actions undertaken is the establishment of an appropriate legal and regulatory framework for space resource utilization activities to provide private companies and investors with a secure legal environment.
WASHINGTON (NASA PR) — The global space economy is growing, generating more than $300 billion a year in space-related activities, and attracting new, diverse participants and investors. A recent study also found more private money invested in commercial space development in 2015 than in the previous 15 years combined.
NASA has selected six new research proposals to understand the effective drivers of investments in the space economy.
Somewhere out there in the cosmos, there’s a giant rock with Earth’s name on it. Despite the danger, NASA’s effort to identify potentially dangerous near Earth objects and figure out what to do about them is disorganized and poorly managed, an internal audit has found.
“NASA has organized its NEO Program under a single Program Executive who manages a loosely structured conglomerate of research activities that are not well integrated and lack overarching Program oversight, objectives, and established milestones to track progress,” according to an audit issued Monday by NASA’s Office of Inspector General (OIG).
Aviation Week reports that European space officials will spend the summer reviewing the prospects of NASA’s asteroid retrieval mission even as the proposal struggles to gain support in Congress:
Jean Jacques Dordain, director general of the European Space Agency (ESA), told Bolden he has set up a multi-agency working group headed by ESA human-spaceflight chief Thomas Reiter “tasked to elaborate a coherent approach with regard to your new initiative.”
Representatives of the national space agencies of France, Germany, Italy and the U.K. will participate in the working group, with a report due from ESA to NASA in September, Dordain told Bolden in a June 20 letter.
“[W]e welcome this new initiative and are ready to support discussions on potential cooperation that would strengthen ongoing and future space exploration activities to be performed in an international framework,” Dordain wrote.
However, he noted that ESA’s human spaceflight strategy includes the International Space Station in low Earth orbit, the Moon and Mars. NASA’s idea is to capture a small near-Earth asteroid, nudge it into high retrograde lunar orbit with solar electric propulsion, and send astronauts in an Orion crew vehicle to study it.
