NASA’s OSIRIS-REx spacecraft makes closest flyover of landing site Nightingale on asteroid Bennu

 

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – Preliminary results indicate that NASA’s OSIRIS-REx spacecraft successfully executed a 0.4-mile (620-m) flyover of site Nightingale yesterday as part of the mission’s Reconnaissance B phase activities. Nightingale, OSIRIS-REx’s primary sample collection site, is located within a crater high in asteroid Bennu’s northern hemisphere.

To perform the pass, the spacecraft left its 0.75-mile (1.2-km) safe home orbit and flew an almost 11-hour transit over the asteroid, aiming its science instruments toward the 52-ft (16-m) wide sample site before returning to orbit.

During the OSIRIS-REx Reconnaissance B flyover of primary sample collection site Nightingale, the spacecraft left its safe-home orbit to pass over the sample site at an altitude of 0.4 miles (620 m). The pass, which took 11 hours, gave the spacecraft’s onboard instruments the opportunity to take the closest-ever science observations of the sample site. (NASA/Goddard/University of Arizona)

What’s NASA Scientists Favorite Christmas Gift? Box Apollo Moon Soil

 

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – Fortunately for NASA scientists today, Apollo-era leaders had the foresight to save much of the 842 pounds (382 kilograms) of Moon soil and rocks retrieved by NASA astronauts 50 years ago for future generations. They figured new crops of scientists, using instruments of their time, would be able to probe the samples with unprecedented rigor.

Now, the future that Apollo-era scientists envisioned has come. Their successors, many of whom weren’t even born when the last astronauts scooped up the Moon samples they’ll now be probing in their labs, are ready to take a giant leap towards answering long-standing questions about the evolution of our solar system.

The scientists who work in this lab analyze amino acids in Apollo samples, meteorites, and comet dust — in other words, in well-preserved remnants of the early solar system.

NASA picks spot on Asteroid Bennu to collect Samples

 

NASA - National Aeronautics and Space AdministrationWashington, D.C. – After a year scoping out asteroid Bennu’s boulder-scattered surface, the team leading NASA’s first asteroid sample return mission has officially selected a sample collection site.

The Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer (OSIRIS-Rex) mission team concluded a site designated “Nightingale” – located in a crater high in Bennu’s northern hemisphere – is the best spot for the OSIRIS-REx spacecraft to snag its sample.

NASA’s OSIRIS-REx Spacecraft offers insight into Particles being ejected from Asteroid Bennu

 

NASA - National Aeronautics and Space AdministrationPasadena, CA – Shortly after NASA’s OSIRIS-REx spacecraft arrived at asteroid Bennu, an unexpected discovery by the mission’s science team revealed that the asteroid could be active, or consistently discharging particles into space. The ongoing examination of Bennu – and its sample that will eventually be returned to Earth – could potentially shed light on why this intriguing phenomenon is occurring.

The OSIRIS-REx team first observed a particle-ejection event in images captured by the spacecraft’s navigation cameras taken on January 6th, just a week after the spacecraft entered its first orbit around Bennu.

This view of asteroid Bennu ejecting particles from its surface on Jan. 6, 2019, was created by combining two images taken by the NavCam 1 imager aboard NASA's OSIRIS-REx spacecraft: a short exposure image, which shows the asteroid clearly, and a long-exposure image (five seconds), which shows the particles clearly.

NASA’s OSIRIS-REx Spacecraft has Four Possible Sites to gather samples on Asteroid Bennu

 

NASA - National Aeronautics and Space AdministrationWashington, D.C. – The team leading NASA’s first asteroid sample return mission has selected four potential sites for the Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) spacecraft to “tag” its cosmic dance partner after months grappling with the rugged reality of asteroid Bennu’s surface.

Since its arrival in December 2018, the OSIRIS-REx spacecraft has mapped the entire asteroid in order to identify the safest and most accessible spots for the spacecraft to collect a sample. These four sites now will be studied in further detail in order to select the final two sites – a primary and backup – in December.

Pictured are the four candidate sample collection sites on asteroid Bennu selected by NASA’s OSIRIS-REx mission. Site Nightingale (top left) is located in Bennu’s northern hemisphere. Sites Kingfisher (top right) and Osprey (bottom left) are located in Bennu’s equatorial region. Site Sandpiper (bottom right) is located in Bennu’s southern hemisphere. In December, one of these sites will be chosen for the mission’s touchdown event. (NASA/University of Arizona)

NASA lists 10 Things You Should Know About Planetary Defense

 

NASA Headquarters 

NASA - National Aeronautics and Space AdministrationWashington, D.C.1. Why Asteroids Impact Earth: Why do asteroids and meteoroids collide with Earth?

NASA says these objects orbit the Sun just like the planets, as they have been doing for billions of years, but small effects such as gravitational nudges from the planets can jostle the orbits, making them gradually shift over million-year timescales or abruptly reposition if there is a close planetary encounter.

These three radar images of near-Earth asteroid 2003 SD220 were obtained on Dec. 15-17, by coordinating observations with NASA's 230-foot (70-meter) antenna at the Goldstone Deep Space Communications Complex in California and the National Science Foundation's (NSF) 330-foot (100-meter) Green Bank Telescope in West Virginia.

NASA’s OSIRIS-REx spacecraft discovers plumes erupting on asteroid Bennu

 

NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – A NASA spacecraft that will return a sample of a near-Earth asteroid named Bennu to Earth in 2023 made the first-ever close-up observations of particle plumes erupting from an asteroid’s surface. Bennu also revealed itself to be more rugged than expected, challenging the mission team to alter its flight and sample collection plans, due to the rough terrain. 

Bennu is the target of NASA’s Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) mission, which began orbiting the asteroid on December 31st. Bennu, which is only slightly wider than the height of the Empire State Building, may contain unaltered material from the very beginning of our solar system.

This view of asteroid Bennu ejecting particles from its surface on January 19 was created by combining two images taken on board NASA’s OSIRIS-REx spacecraft. Other image processing techniques were also applied, such as cropping and adjusting the brightness and contrast of each image. (NASA/Goddard/University of Arizona/Lockheed Martin)
