Editor’s Note:
As the Planetary Defense Conference gets underway in Flagstaff, Ariz., NASA reports progress on a sensor designed to detect asteroids and comets.

PASADENA, Calif. (NASA PR) – An infrared sensor that could improve NASA’s future detecting and tracking of asteroids and comets has passed a critical design test.

The test assessed performance of the Near Earth Object Camera (NEOCam) in an environment that mimicked the temperatures and pressures of deep space. NEOCam is the cornerstone instrument for a proposed new space-based asteroid-hunting telescope. Details of the sensor’s design and capabilities are published in an upcoming edition of the Journal of Optical Engineering.

SANTA MONICA, CALIF. (DSI PR) –
Deep Space Industries announced today that it will send a fleet of asteroid-prospecting spacecraft out into the solar system to hunt for resources to accelerate space development to benefit Earth.  These “FireFly” spacecraft utilize low-cost cubesat components and get discounted delivery to space by ride-sharing on the launch of larger communications satellites.

Move over, Peter D! You’ve got company!

Former Astrobotic Technology President David Gump has resurfaced with a new company, Deep Space Industries, which will announce the “world’s first fleet of commercial asteroid-prospecting spacecraft” during a press conference at the Santa Monica Museum of Flying on Tuesday, Jan. 22.

Deep Space Industries is the second asteroid mining company to make a public announcement in the past year. Planetary Resources — founded by Peter Diamandis and Eric Anderson — is aiming for the same market.

Eric Berger over at Space News has more information on the company.

Russia Eyes New Agency to Monitor NEOs, Space Debris

Comment

Asteroid Ida

Roscosmos held a meeting last week during officials reviewed a plan for meeting threats to Russia from both near Earth objects (NEOs) and space debris. One of the key recommendations was the establishment of a new agency to oversee the effort:

“Proposed the creation of a single (national) Monitoring Space Administration (SMC) to integrate information from the space control system (SKKP) Russian Defense Ministry and a set of specialized tools to detect and monitor hazardous space objects operated by industry organizations (Roscosmos, Russia Ministry of Industry) and the Russian Academy of Sciences.”

A Roscosmos press release that outlines the recommendations is reproduced below via Google Translate.

B612 Foundation Get Support for Asteroid Hunting Spacecraft

Comments

MOUNTAIN VIEW, CA, September 19, 2012 (B612 PR) – The world’s first privately funded deep space mission – SENTINEL – received major support this week from prominent members of the business and financial community who joined the B612 Foundation’s Founding Circle. Founding Circle Members not only contribute substantial funding to the mission, but also pledge continued support in multiple areas of finance, technology and science.

Sentinel Overview and Specifications

Comments


Sentinel Overview

Sentinel is a space-based infrared (IR) survey mission to discover and catalog 90 percent of the asteroids larger than 140 meters in Earth’s region of the solar system. The mission should also discover a significant number of smaller asteroids down to a diameter of 30 meters. Sentinel will be launched into a Venus-like orbit about the sun which significantly improves the efficiency of asteroid discovery during its 5.5 year mission.

B-612 Plans Infrared Asteroid Seeking Telescope

Comments

The B-612 Foundation is set to unveil plans for its privately-funded asteroid hunting orbital telescope on Thursday at noon EDT (9 a.m. PDT; 1600 GMT) during a press conference in San Francisco.

Bill Nye the Science Guy provided some early intel on the project for about 40 attendees at the monthly LA Space Salon on Wednesday. Nye, who is scheduled to fly up to San Francisco for the press conference on Thursday morning, described the plan as follows:

The foundation will place an infrared telescope (originally called Sentinel but since renamed) into space at approximately the orbit of Venus (.7 AU). It will look out at the solar system with the sun at its back. An infrared instrument is being used because asteroids reflect well in this spectrum. It is believed that there are as many as 100,000 Earth-crossing asteroids.

Funding for the telescope is coming from investors in Silicon Valley. Nye mentioned that officials had met with Elon Musk of SpaceX, although he wasn’t clear on whether the company had agreed to launch the telescope.

UPDATE:  The telescope is indeed called SENTINEL and plans call for launching it on a SpaceX Falcon 9.

B612 Foundation to Announce First Privately Funded Deep Space Mission

Comment

B612 FOUNDATION TO ANNOUNCE
FIRST PRIVATELY FUNDED DEEP SPACE MISSION

Who: The B612 Foundation

What: Press Conference to Launch the B612 Foundation and Sentinel Space Telescope Mission-the first privately funded deep space mission.

When: Thursday, June 28, 2012 — 8:30 AM – 11:00 AM (PT)

Where: Morrison Planetarium, California Academy of Sciences, 55 Music Concourse Drive, San Francisco, CA, in Golden Gate Park. (Pay Parking in CA Academy Garage)

Announcement: On June 28, 2012, the B612 Foundation will announce its plans to build, operate and launch the world’s first privately funded deep space mission–a space telescope to be placed in orbit around the Sun. We will create the first comprehensive dynamic map of our inner solar system showing the current and future locations and trajectories of Earth-crossing asteroids, paving the way to protect the Earth from future impacts and opening up the Solar System to future exploration.

Speakers at the June 28 Press Conference:

  • Ed Lu, Chairman & CEO,former Space Shuttle/ISS/Soyuz Astronaut
  • Rusty Schweickart, Chairman Emeritus,Lunar Module Pilot, Apollo 9
  • Scott Hubbard, Project Architect,Stanford University, former Dir., NASA Ames
  • Harold Reitsema, Mission Director,former Dir. Science Mission Dev., Ball Aerospace

The B612 Foundation (www.b612foundation.org) aims to build, launch, and operate the world’s first privately funded deep space telescope mission to create the first comprehensive dynamic map of our inner solar system, identifying the current and future locations and trajectories of Earth crossing asteroids. Mapping the great unknown of the inner solar system is the first step to opening up this next frontier. The B612 Foundation believes that humanity can harness the power of science and technology to protect the future of civilization on this planet, while extending our reach into the solar system.

Killer Asteroids: A Lot More Than We Thought

New results from NASA's NEOWISE survey find that more potentially hazardous asteroids, or PHAs, are closely aligned with the plane of our solar system than previous models suggested. Image credit: NASA/JPL-Caltech

WASHINGTON (NASA PR) — Observations from NASA’s Wide-field Infrared Survey Explorer (WISE) have led to the best assessment yet of our solar system’s population of potentially hazardous asteroids. The results reveal new information about their total numbers, origins and the possible dangers they may pose.

Potentially hazardous asteroids, or PHAs, are a subset of the larger group of near-Earth asteroids. The PHAs have the closest orbits to Earth’s, coming within five million miles (about eight million kilometers) and they are big enough to survive passing through Earth’s atmosphere and cause damage on a regional, or greater, scale.

The new results come from the asteroid-hunting portion of the WISE mission, called NEOWISE. The project sampled 107 PHAs to make predictions about the entire population as a whole. Findings indicate there are roughly 4,700 PHAs, plus or minus 1,500, with diameters larger than 330 feet (about 100 meters). So far, an estimated 20 to 30 percent of these objects have been found.
