NASA Analysis: Earth Is Safe From Asteroid Apophis for 100-Plus Years

These images of asteroid Apophis were recorded by radio antennas at the Deep Space Network’s Goldstone complex in California and the Green Bank Telescope in West Virginia. The asteroid was 10.6 million miles (17 million kilometers) away, and each pixel has a resolution of 127 feet (38.75 meters). (Credits: NASA/JPL-Caltech and NSF/AUI/GBO)

The near-Earth object was thought to pose a slight risk of impacting Earth in 2068, but now radar observations have ruled that out.

PASADENA, Calif. (NASA PR) — After its discovery in 2004, asteroid 99942 Apophis had been identified as one of the most hazardous asteroids that could impact Earth. But that impact assessment changed as astronomers tracked Apophis and its orbit became better determined.

Now, the results from a new radar observation campaign combined with precise orbit analysis have helped astronomers conclude that there is no risk of Apophis impacting our planet for at least a century.

National Space Council Fact Sheet

By Establishing a National Strategy for Planetary Protection, the United States Continues to Lead in the Safe and Sustainable Exploration and Commercialization of Space

PLANETARY PROTECTION FOR THE 21ST CENTURY: The National Space Council released a strategy to ensure the protection of the Earth and other planetary bodies from harmful biological contamination from space exploration activities.

  • As the United States continues to lead in space exploration and commercialization, national policy must keep pace to accelerate our world-class commercial space sector and scientific enterprise, while appropriately avoiding biological contamination.
  • Many aspects of planetary protection policy have not been updated since the Apollo Era and do not reflect the increasing role and capabilities of the private sector.
  • Planetary protection against “forward contamination” ensures the validity of potential scientific discoveries in the search for extraterrestrial life.
  • Planetary protection against “backward contamination” ensures that the Earth’s biosphere is not adversely affected by the return of potentially hazardous microbes.

ADVANCING SPACE EXPLORATION LEADERSHIP: The National Strategy for Planetary Protection advances U.S. interests in science and exploration, commercial space activity, and international leadership.

  • This strategy outlines steps to implement direction from the 2020 National Space Policy for the White House Office of Science and Technology Policy to lead U.S. departments and agencies in the development of planetary protection operational guidelines.
  • Meeting the strategy’s objectives will ensure a cohesive national effort that balances scientific discovery, human exploration, and commercial activity in space, while meeting applicable international and domestic obligations.
  • The United States will continue to lead in the sustainable exploration of space by appropriately protecting the Earth and other celestial bodies.
  • Best practices developed by the United States that account for commercial and international partners will ensure safety, sustainability, and predictability in space for the benefit of all humankind.

NASA Perseveres Through Pandemic to Complete Successful 2020

WASHINGTON (NASA PR) — In 2020, NASA made significant progress on America’s Moon to Mars exploration strategy, met mission objectives for the Artemis program, achieved significant scientific advancements to benefit humanity, and returned human spaceflight capabilities to the United States, all while agency teams acted quickly to assist the national COVID-19 response.

ISRO Opens Space Situational Awareness Center

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.

NASA, U.S. Space Force Sign MOU to Deepen Cooperation

WASHINGTON (NASA PR) — While advancing plans for unprecedented lunar exploration under the Artemis program, NASA also is building on a longstanding partnership with the Department of Defense with a new memorandum of understanding announced today by NASA Administrator Jim Bridenstine and U.S. Space Force (USSF) Chief of Space Operations Gen. John “Jay” Raymond.

The agreement, discussed during a Sept. 22 Mitchell Institute virtual event, commits the two organizations to broad collaboration in areas including human spaceflight, U.S. space policy, space transportation, standards and best practices for safe operations in space, scientific research, and planetary defense.
