NASA reports large Asteroid 2001 FO32 to safely fly past Earth, March 21st

 

NASA - National Aeronautics and Space AdministrationPasadena, CA – The largest asteroid predicted to pass by our planet in 2021 will be at its closest on March 21st, providing astronomers a rare opportunity to get a good look at a rocky relic that formed at the dawn of our solar system.

Called 2001 FO32, the near-Earth asteroid will make its closest approach at a distance of about 1.25 million miles (2 million kilometers) – or 5 1/4 times the distance from Earth to the Moon. There is no threat of a collision with our planet now or for centuries to come.

This diagram depicts the elongated and inclined orbit of 2001 FO32 as it travels around the Sun (white ellipse). Because of this orbit, when the asteroid makes its close approach to Earth, it will be traveling at an unusually fast speed of 77,000 mph (124,000 kph). (NASA/JPL-Caltech)

NASA’s OSIRIS-REx spacecraft searches Asteroid Bennu’s surface for safe areas to land

 

NASA - National Aeronautics and Space AdministrationWashington, D.C. – This summer, the OSIRIS-REx spacecraft will undertake NASA’s first-ever attempt to touch the surface of an asteroid, collect a sample of it, and safely back away. But since arriving at asteroid Bennu over a year ago, the mission team has been tackling an unexpected challenge: how to accomplish this feat at an asteroid whose surface is blanketed in building-sized boulders.

Using these hazardous boulders as signposts, the mission team developed a new precision navigation method to overcome the challenge.

During the sample collection event, Natural Feature Tracking (NFT) will guide NASA’s OSIRIS-REx spacecraft to asteroid Bennu’s surface. The spacecraft takes real-time images of the asteroid’s surface features as it descends, and then compares these images with an onboard image catalog. The spacecraft then uses these geographical markers to orient itself and accurately target the touchdown site. (NASA/Goddard/University of Arizona)

NASA to test Planetary Defense Technology against Asteroid in 2022

 

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA’s first mission to demonstrate a planetary defense technique, the Double Asteroid Redirection Test (DART), will get one chance to hit its target, the small moonlet in the binary asteroid system Didymos.

The asteroid poses no threat to Earth and is an ideal test target: measuring the change in how the smaller asteroid orbits about the larger asteroid in a binary system is much easier than observing the change in a single asteroid’s orbit around the Sun.

NASA reports First Known Interstellar Object to enter our Solar System speeds up and changes directions

 

NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Using observations from NASA’s Hubble Space Telescope and ground-based observatories, an international team of scientists has confirmed ‘Oumuamua (oh-MOO-ah-MOO-ah), the first known interstellar object to travel through our solar system, got an unexpected boost in speed and shift in trajectory as it passed through the inner solar system last year.

“Our high-precision measurements of ‘Oumuamua’s position revealed that there was something affecting its motion other than the gravitational forces of the Sun and planets,” said Marco Micheli of ESA’s (European Space Agency) Space Situational Awareness Near-Earth Object Coordination Centre in Frascati, Italy, and lead author a paper describing the team’s findings.

This artist's illustration shows 'Oumuamua racing toward the outskirts of our solar system, and is annotated with the locations of the planetary orbits. As the complex rotation of the object makes it difficult to determine the exact shape, there are many models of what it could look like. (NASA)

NASA’S OSIRIS-REx Spacecraft uses Earth’s Gravity to Slingshot toward Asteroid Bennu

 

Written by Nancy Neal Jones
NASA’s Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – NASA’s asteroid sample return spacecraft successfully used Earth’s gravity on Friday to slingshot itself on a path toward the asteroid Bennu, for a rendezvous next August.

At 12:52pm EDT on September 22nd, 2017 the OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, and Security – Regolith Explorer) spacecraft came within 10,711 miles (17,237 km) of Antarctica, just south of Cape Horn, Chile, before following a route north over the Pacific Ocean.

NASA readies OSIRIS-REx spacecraft for September Launch

 

Written by Nancy Neal Jones
NASA’s Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – NASA’s first spacecraft designed to return a piece of an asteroid to Earth arrived Friday, May 20th, at the agency’s Kennedy Space Center in Florida, and has begun final preparations in advance of its September launch.

The Origins, Spectral Interpretation, Resource Identification, Security – Regolith Explorer (OSIRIS-REx) spacecraft will undergo final testing and fueling prior to being moved to its launch pad. The mission has a 34-day launch period beginning on September 8th.

After launch, the OSIRIS-REx spacecraft will travel to the near-Earth asteroid Bennu and retrieve at least 60 grams (2.1 ounces) of pristine surface material and return it to Earth for study.

NASA's OSIRIS-REx spacecraft is revealed after its protective cover is removed inside the Payload Hazardous Servicing Facility at Kennedy Space Center in Florida. The spacecraft traveled from Lockheed Martin's facility near Denver, Colorado to Kennedy to begin processing for its upcoming launch, targeted for Sept. 8 aboard a United Launch Alliance Atlas V rocket.
