GREENBELT, Md. (NASA PR) — Captured on Apr. 14 during the first rehearsal of the OSIRIS-REx mission’s sample collection event, this series of images shows the navigation camera’s (NavCam 2) field of view as the NASA spacecraft approaches and moves away from asteroid Bennu’s surface.

The rehearsal brought the spacecraft through the first two maneuvers of the sampling sequence to a point approximately 213 feet (65 meters) above the surface, after which the spacecraft performed a back-away burn.

Checkpoint: OSIRIS-REx Practices Sample Collection

GREENBELT, Md. (NASA PR) — In August, the robotic spacecraft will make NASA’s first-ever attempt to descend to the surface of an asteroid, collect a sample and ultimately bring it safely back to Earth.

In order to achieve this challenging feat, the mission team devised new techniques to operate in asteroid Bennu’s microgravity environment – but they still need experience flying the spacecraft in close proximity to the asteroid in order to test them.

So, before touching down at sample site Nightingale this summer, OSIRIS-REx will first rehearse the activities leading up to the event.

On Apr. 14, the mission will pursue its first practice run – officially known as “Checkpoint” rehearsal – which will also place the spacecraft the closest it’s ever been to Bennu. This rehearsal is a chance for the OSIRIS-REx team and spacecraft to test the first steps of the robotic sample collection event.

There will be a four-hour social media campaign on @OSIRISREx and @NASASolarSystem.

OSIRIS-REx Swoops Over Sample Site Nightingale

On Mar. 3, the OSIRIS-REx spacecraft performed a low-altitude flyover of site Nightingale. During the pass, science observations of asteroid Bennu took place from a distance of approximately 820 ft (250 m) – the closest the spacecraft has ever been to the asteroid’s surface.

OSIRIS-REx Mission Update
March 4, 2020

NASA’s first asteroid-sampling spacecraft just got its best look yet at asteroid Bennu. Yesterday, the OSIRIS-REx spacecraft executed a very low pass over sample site Nightingale, taking observations from an altitude of 820 feet (250 m), which is the closest that OSIRIS-REx has flown over the asteroid so far. Nightingale, OSIRIS-REx’s primary sample collection site, is located within a crater in Bennu’s northern hemisphere.

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.

NASA’s OSIRIS-REx Mission Explains Bennu’s Mysterious Particle Events

This view of asteroid Bennu ejecting particles from its surface on January 6 was created by combining two images taken by the NavCam 1 imager onboard NASA’s OSIRIS-REx spacecraft: a short exposure image (1.4 ms), which shows the asteroid clearly, and a long exposure image (5 sec), which shows the particles clearly. Other image processing techniques were also applied, such as cropping and adjusting the brightness and contrast of each layer. (Credits: NASA/Goddard/University of Arizona/Lockheed Martin)

GREENBELT, Md. (NASA PR) — 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.

NASA Funds Research into Food Production on Deep Space Missions

As NASA contemplates deep space missions to the moon and Mars, the space agency faces increasing challenges in keeping its astronauts physically and mentally healthy.

One of the key elements in that challenge is fresh food. Currently, fresh produce is supplied periodically to astronauts aboard the International Space Station (ISS) on resupply ships. Crew members have also grown small quantities of vegetables on board.

Resupply becomes a more difficult task on deep space missions due to distance. Thus, astronauts will need to grow more of their own food. Last week, NASA announced three Small Business Technology Transfer (STTR) awards to advance that goal.

Asteroid Bennu’s Features to be Named After Mythical Birds

Greenbelt, Md. (NASA PR) — Working with NASA’s OSIRIS-REx team, the International Astronomical Union’s Working Group for Planetary System Nomenclature (WGPSN) approved the theme “birds and bird-like creatures in mythology” for naming surface features on asteroid (101955) Bennu.

UA College of Medicine

PHOENIX (UA PR) — Researchers at the University of Arizona College of Medicine – Phoenix are partnering with Space Tango, a private aerospace company that designs, builds and operates facilities on the International Space Station, to develop an easy way to test astronauts’ health in space.

Led by Frederic Zenhausern, director of the UA Center for Applied NanoBioscience and Medicine, the project has received three independent NASA grants. The latest funding will allow researchers to develop a diagnostic tool – a miniature syringe-like device that can detect bioagents and hundreds of biomarkers in blood or saliva – and test it in space.

A Region of Bennu’s Northern Hemisphere Close Up

This trio of images acquired by NASA’s OSIRIS-REx spacecraft shows a wide shot and two close-ups of a region in asteroid Bennu’s northern hemisphere. The wide-angle image (left), obtained by the spacecraft’s MapCam camera, shows a 590-foot (180-meter) wide area with many rocks, including some large boulders, and a “pond” of regolith that is mostly devoid of large rocks.

The two closer images, obtained by the high-resolution PolyCam camera, show details of areas in the MapCam image, specifically a 50-foot (15 meter) boulder (top) and the regolith pond (bottom). The PolyCam frames are 101 feet (31 meters) across and the boulder depicted is approximately the same size as a humpback whale.

The images were taken on February 25 while the spacecraft was in orbit around Bennu, approximately 1.1 miles (1.8 km) from the asteroid’s surface. The observation plan for this day provided for one MapCam and two PolyCam images every 10 minutes, allowing for this combination of context and detail of Bennu’s surface.











NASA’s OSIRIS-REx Spacecraft Enters Close Orbit Around Bennu, Breaking Record

TUCSON (University of Arizona PR) — At 2:43 p.m. EST on December 31, while many on Earth prepared to welcome the New Year, NASA’s OSIRIS-REx spacecraft, 70 million miles (110 million kilometers) away, carried out a single, eight-second burn of its thrusters – and broke a space exploration record. The spacecraft entered into orbit around the asteroid Bennu, and made Bennu the smallest object ever to be orbited by a spacecraft.

OSIRIS-REx Captures ‘Super-Resolution’ View of Bennu

Asteroid Bennu (Credit: Credit: NASA/Goddard/University of Arizona)

This “super-resolution” view of asteroid Bennu was created using eight images obtained by NASA’s OSIRIS-REx spacecraft on Oct. 29, 2018, from a distance of about 205 miles (330 km). The spacecraft was moving as it captured the images with the PolyCam camera, and Bennu rotated 1.2 degrees during the nearly one minute that elapsed between the first and the last snapshot. The team used a super-resolution algorithm to combine the eight images and produce a higher resolution view of the asteroid. Bennu occupies about 100 pixels and is oriented with its north pole at the top of the image.

OSIRIS-REx Captures Rotation of Asteroid Bennu

This set of images, taken with OSIRIS-REx’s PolyCam camera on Oct. 23, 2018, shows three views of asteroid Bennu as it rotates over a span of five hours. At the time the images were taken, Bennu was about 1,800 miles (3,000 km) away from the spacecraft and appears about 13 pixels across in the camera’s field of view. In this set of images, the spacecraft’s camera is beginning to detect noticeable differences on each side of Bennu as the asteroid rotates.

PASADENA, Calif. (NASA/JPL/Caltech PR) — These six infrared images of Saturn’s moon Titan represent some of the clearest, most seamless-looking global views of the icy moon’s surface produced so far. The views were created using 13 years of data acquired by the Visual and Infrared Mapping Spectrometer (VIMS) instrument on board NASA’s Cassini spacecraft. The images are the result of a focused effort to smoothly combine data from the multitude of different observations VIMS made under a wide variety of lighting and viewing conditions over the course of Cassini’s mission.
