BANGALORE, India (ISRO PR) — In view of ever-growing population of space objects and the recent trend towards mega-constellations, Space Situational Awareness (SSA) has become an integral and indispensable part of safe and sustainable space operations.
For the last few decades, ISRO has been carrying out SSA activities, mainly focused on safeguarding India’s space assets. Recognising the need for dedicated efforts to tackle the emerging challenges of operating in an exceedingly crowded and contested space domain, Directorate of Space Situational Awareness and Management (DSSAM) has been established at ISRO.
The Directorate engages in evolving improved operational mechanisms to protect Indian space assets through effective coordination amongst ISRO/DOS Centres, other space agencies and international bodies, and establishment of necessary supporting infrastructures, such as additional observation facilities for space object monitoring, and a control centre for centralized SSA activities.
WASHINGTON (NASA PR) — On Nov. 18, NASA was informed by the National Science Foundation (NSF) that, after careful assessment and consideration, they have decided to decommission the 305m radio telescope at the Arecibo Observatory in Puerto Rico, which recently sustained structural damage from failed cables.
I looked a bit more into this memorandum of understanding (MOU) that was signed earlier this week by NASA and the U.S. Space Force (USSF) to deepen cooperation between the two agencies. And there’s a really fascinating aspect to it.
“With new U.S. public and private sector operations extending into cislunar space, the reach of USSF’s sphere of interest will extend to 272,000 miles and beyond — more than a tenfold increase in range and 1,000-fold expansion in service volume,” the MOU said.
NASA’s Planetary Science Division (PSD) faces a series of managerial, financial and personnel challenges as it prepares to conduct a series of ever more ambitious missions to the moon and planets, according to a new audit by the space agency’s Office of Inspector General (IG).
An SUV-size space rock flew past our planet over the weekend and was detected by a NASA-funded asteroid survey as it departed.
PASADENA, Calif. (NASA PR) — Near Earth Asteroids, or NEAs, pass by our home planet all the time. But an SUV-size asteroid set the record this past weekend for coming closer to Earth than any other known NEA: It passed 1,830 miles (2,950 kilometers) above the southern Indian Ocean on Sunday, Aug. 16 at 12:08 a.m. EDT (Saturday, Aug. 15 at 9:08 p.m. PDT).
NEW YORK (Springer PR) — Our planet exists within the vicinity of thousands of Near-Earth Objects (NEOs), some of which — Potentially Hazardous Asteroids (PHAs) — carry the risk of impacting Earth causing major damage to infrastructure and loss of life. Methods to mitigate such a collision are highly desirable.
BENGALURU, India (ISRO PR) — A Memorandum of Understanding (MoU) between Indian Space Research Organization (ISRO), Bengaluru and Aryabhatta Research Institute of Observational Sciences (ARIES), Nainital for cooperation in the field of Space Situational Awareness (SSA) and Astrophysics was signed by Shri.R. Umamaheswaran, Scientific Secretary, ISRO and Prof. (Dr.) Dipankar Banerjee, Director, ARIES through video at ISRO Headquarters and ARIES Headquarters on 4th June 2020.
TUCSON, Ariz. (University of Arizona PR) — The University of Arizona is spearheading work that would begin efforts to construct a space-based infrared telescope that could provide the capabilities NASA needs to search for asteroids and comets that pose impact hazards to Earth, called near-Earth objects, or NEOs.
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.
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.
PASADENA, Calif. (NASA PR) — A newly discovered comet has excited the astronomical community this week because it appears to have originated from outside the solar system. The object — designated C/2019 Q4 (Borisov) — was discovered on Aug. 30, 2019, by Gennady Borisov at the MARGO observatory in Nauchnij, Crimea. The official confirmation that comet C/2019 Q4 is an interstellar comet has not yet been made, but if it is interstellar, it would be only the second such object detected. The first, ‘Oumuamua, was observed and confirmed in October 2017.
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.
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.
