The new system improves the capabilities of NASA JPL’s Center for Near Earth Object Studies to assess the impact risk of asteroids that can come close to our planet.

PASADENA, Calif. (NASA PR) — To date, nearly 28,000 near-Earth asteroids (NEAs) have been found by survey telescopes that continually scan the night sky, adding new discoveries at a rate of about 3,000 per year. But as larger and more advanced survey telescopes turbocharge the search over the next few years, a rapid uptick in discoveries is expected. In anticipation of this increase, NASA astronomers have developed a next-generation impact monitoring algorithm called Sentry-II to better evaluate NEA impact probabilities.

FRASCATI, Italy (ESA PR) — The new heart of ESA’s Planetary Defence Office was inaugurated today, heralding a new chapter in the Agency’s work to protect Earth from dangerous near-Earth objects, aka asteroids.

For years, ESA has been dedicated to opening our eyes to hazards in space, and when it came to asteroids this meant ensuring Europe had the capability to detect, track and understand what’s out there.

WASHINGTON (NASA PR) — In a study released Wednesday, NASA researchers used precision-tracking data from the agency’s Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) spacecraft to better understand movements of the potentially hazardous asteroid Bennu through the year 2300, significantly reducing uncertainties related to its future orbit, and improving scientists’ ability to determine the total impact probability and predict orbits of other asteroids.

The study, titled “Ephemeris and hazard assessment for near-Earth asteroid (101955) Bennu based on OSIRIS-REx data,” was published in the journal Icarus.

Qorvo Provides Key Enabling Technology for Identifying, Mapping and Tracking Threats from Near-Earth Objects

The National Radio Astronomy Observatory (NRAO), Green Bank Telescope, and Raytheon Intelligence & Space (RI&S) are working in collaboration to improve planetary radar capabilities. With the addition of Qorvo’s Spatium power amplifier technology, the project now has the power to identify and characterize even small NEOs earlier with more precision. (Credit: NRAO/AUI/NSF, S. Dagnello)

GREENSBORO, NC (Qorvo PR) — Qorvo® (Nasdaq: QRVO), a leading provider of innovative radio frequency (RF) solutions that connect the world, today announced its Spatium® solid-state power amplifier (SSPA) technology will play a key role in a new planetary radar experiment using the Green Bank Telescope in West Virginia. Planetary radar is instrumental in characterizing Near-Earth Objects (NEOs) by providing precision measurement of shape, rotation, position, and an estimate of composition.

The infrared space telescope is designed to help advance NASA’s planetary defense efforts.

PASADENA, Calif. (NASA PR) — NASA has approved the Near-Earth Object Surveyor space telescope (NEO Surveyor) to move to the next phase of mission development after a successful mission review, authorizing the mission to move forward into Preliminary Design (known as Key Decision Point-B). The infrared space telescope is designed to help advance NASA’s planetary defense efforts by expediting our ability to discover and characterize most of the potentially hazardous asteroids and comets that come within 30 million miles of Earth’s orbit, collectively known as near-earth objects, or NEOs.

  • ESA’s second Test-Bed Telescope has seen ‘first light’.
  • It will help spot asteroids in space that could pose a risk to Earth.
  • This telescope is the latest step towards ESA’s planned Flyeye telescope network.
  • It is hosted at the European Southern Observatory’s La Silla Observatory in Chile.

COQUIMBO REGION, Chile (ESA PR) — ESA’s second Test-Bed Telescope, hosted at the European Southern Observatory’s (ESO) La Silla Observatory in Chile, has seen ‘first light’ – when a new telescope is first used to look up.

There are 3 key reasons why it is vital for NASA to develop better ways to locate and characterize Near Earth Objects (NEOs).

1: NEOs are an impact hazard to the Earth.

2: Measuring NEO population distributions will unlock the answers to critical questions dealing with the formation and evolution of the solar system.

3: Most importantly, low ∆V NEOs can be targets for human exploration and resource mining.

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.

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.
