X MARKS THE SPOT: NASA SELECTS SITE FOR ASTEROID SAMPLE COLLECTION

December 12, 2019 - 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.

The OSIRIS-REx team spent the past several months evaluating close-range data fr om four candidate sites in order to identify the best option for the sample collection. The candidate sites – dubbed Sandpiper, Osprey, Kingfisher, and Nightingale – were chosen for investigation because, of all the potential sampling regions on Bennu, these areas pose the fewest hazards to the spacecraft's safety while still providing the opportunity for great samples to be gathered.

"After thoroughly evaluating all four candidate sites, we made our final decision based on which site has the greatest amount of fine-grained material and how easily the spacecraft can access that material while keeping the spacecraft safe," said Dante Lauretta, OSIRIS-REx principal investigator at the University of Arizona in Tucson. "Of the four candidates, site Nightingale best meets these criteria and, ultimately, best ensures mission success."

Site Nightingale is located in a northern crater 230 ft (70 m) wide. Nightingale's regolith – or rocky surface material – is dark, and images show that the crater is relatively smooth. Because it is located so far north, temperatures in the region are lower than elsewhere on the asteroid and the surface material is well-preserved. The crater also is thought to be relatively young, and the regolith is freshly exposed. This means the site would likely allow for a pristine sample of the asteroid, giving the team insight into Bennu's history.

Although Nightingale ranks the highest of any location on Bennu, the site still poses challenges for sample collection. The original mission plan envisioned a sample site with a diameter of 164 feet (50 m). While the crater that hosts Nightingale is larger than that, the area safe enough for the spacecraft to touch is much smaller – approximately 52 ft (16 m) in diameter, resulting in a site that is only about one-tenth the size of what was originally envisioned This means the spacecraft has to very accurately target Bennu's surface. Nightingale also has a building-size boulder situated on the crater's eastern rim, which could pose a hazard to the spacecraft while backing away after contacting the site.

The mission also selected site Osprey as a backup sample collection site. The spacecraft has the capability to perform multiple sampling attempts, but any significant disturbance to Nightingale's surface would make it difficult to collect a sample from that area on a later attempt, making a backup site necessary. The spacecraft is designed to autonomously "wave-off" from the site if its predicted position is too close to a hazardous area. During this maneuver, the exhaust plumes from the spacecraft's thrusters could potentially disturb the surface of the site, due to the asteroid's microgravity environment. In any situation wh ere a follow-on attempt at Nightingale is not possible, the team will try to collect a sample from site Osprey instead.

"Bennu has challenged OSIRIS-REx with extraordinarily rugged terrain," said Rich Burns, OSIRIS-REx project manager at NASA's Goddard Space Flight Center. "The team has adapted by employing a more accurate, though more complex, optical navigation technique to be able to get into these small areas. We'll also arm OSIRIS-REx with the capability to recognize if it is on course to touch a hazard within or adjacent to the site and wave-off before that happens."

With the selection of final primary and backup sites, the mission team will undertake further reconnaissance flights over Nightingale and Osprey, beginning in January and continuing through the spring. Once these flyovers are complete, the spacecraft will begin rehearsals for its "touch-and-go" sample collection event, which is scheduled for August. The spacecraft will depart Bennu in 2021 and is scheduled to return to Earth in September 2023.

NASA's Goddard Space Flight Center in Greenbelt, Maryland, provides overall mission management, systems engineering, and the safety and mission assurance for OSIRIS-REx. Dante Lauretta of the University of Arizona, Tucson, is the principal investigator, and the University of Arizona also leads the science team and the mission's science observation planning and data processing. Lockheed Martin Space in Denver built the spacecraft and provides flight operations. Goddard and KinetX Aerospace are responsible for navigating the OSIRIS-REx spacecraft. OSIRIS-REx is the third mission in NASA's New Frontiers Program, which is managed by NASA's Marshall Space Flight Center in Huntsville, Alabama, for the agency's Science Mission Directorate in Washington.

В NASA определили, с какого участка поверхности астероида Бенну будет взята проба грунта
Речь идет об участке, получившем обозначение Nightingale

НЬЮ-ЙОРК, 12 декабря. /ТАСС/. Специалисты Национального управления США по аэронавтике и исследованию космического пространства (NASA) определили участок поверхности астероида Бенну, с которого будет взята проба грунта. Об этом сообщил в четверг на конференции, транслировавшейся на сайте NASA, руководитель программы исследований американской межпланетной станции OSIRIS-REx  Данте Лауретта.

По его словам, после тщательного исследования поверхности астероида, диаметр которого достигает 500 м, ученые первоначально определили 50 участков, представляющих интерес, затем сократили число потенциальных мест забора грунта до четырех, а теперь выбрали один, наиболее подходящий.

"Мы остановились на участке поверхности, получившем обозначение Nightingale, - сообщил он. - Это кратер диаметром около 20 м в северной части астероида. Его дно покрыто мелкими обломками, но у стены кратера есть и несколько крупных глыб, размеры которых превышают 7 м".

В начале 2020 года дистанционный манипулятор станции должен осуществить забор грунта массой около 60 г, затем капсула с образцом направится к Земле. Согласно расчетам, аппарат совершит посадку на территории американского штата Юта в конце сентября 2023 года.

Станция OSIRIS-REx была запущена в космос в сентябре 2016 года в рамках миссии по сближению с астероидом Бенну (1999 RQ36) и сбору образцов с его поверхности. Она достигла небесного тела в начале декабря прошлого года и осуществила съемку всей поверхности астероида.

Asteroid Bennu Sample Site: Nightingale

NASA Goddard

13 дек. 2019 г.

The main science goal of NASA's OSIRIS-REx mission is to briefly touch down on near-Earth asteroid Bennu and collect a sample of fine-grained material, but the asteroid's unexpected roughness could pose a hazard to the spacecraft.

Flyover of Sample Site Nightingale

January 22, 2020 - 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.


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

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. Science observations fr om this flyover are the closest taken of a sample site to date.

The primary goal of the Nightingale flyover was to collect the high-resolution imagery required to complete the spacecraft's Natural Feature Tracking image catalog, which will document the sample collection site's surface features – such as boulders and craters. During the sampling event, which is scheduled for late August, the spacecraft will use this catalog to navigate with respect to Bennu's surface features, allowing it to autonomously predict wh ere on the sample site it will make contact . Several of the spacecraft's other instruments also took observations of the Nightingale site during the flyover event, including the OSIRIS-REx Thermal Emissions Spectrometer (OTES), the OSIRIS-REx Visual and InfraRed Spectrometer (OVIRS), the OSIRIS-REx Laser Altimeter (OLA), and the MapCam color imager.

A similar flyover of the backup sample collection site, Osprey, is scheduled for Feb. 11. Even lower flybys will be performed later this spring – Mar. 3 for Nightingale and May 26 for Osprey – as part of the mission's Reconnaissance C phase activities. The spacecraft will perform these two flyovers at an altitude of 820 feet (250 m), which will be the closest it has ever flown over asteroid Bennu's surface.

OSIRIS-REx совершил первое сближение с поверхностью астероида Бенну
Он детально сфотографировал предположительное место своей будущей посадки

ТАСС, 23 января. Межпланетный зонд OSIRIS-REx вечером в среду успешно сблизилась с поверхностью астероида Бенну в той точке, где специалисты NASA планируют собрать образцы грунта в конце лета этого года. Об этом сообщается на официальном сайте миссии.

"Главная цель пролета над точкой Найтингейл заключалась в том, чтобы получить высококачественные фотографии, которые нужны для того, чтобы каталогизировать все кратеры, булыжники и прочие препятствия, которые есть в этой области астероида. В конце августа OSIRIS-REx будет использовать этот каталог для того, чтобы автономно ориентироваться на поверхности Бенну и определять положение той точки, где будет произведен забор грунта", - говорится в сообщении NASA.

По словам представителей агентства, зонду предстоит еще три подобных пролета над поверхностью астероида. Один из них состоится в середине февраля, а два других - в марте и мае 2020 года. В первом случае он получит фотографии резервной зоны посадки, а два последующих сближения, во время которых аппарат пролетит на расстоянии в 250 метров от поверхности астероида, помогут научной команде миссии определиться с выбором точки, где OSIRIS-REx соберет первые пробы грунта.

Зонд OSIRIS-REx был успешно выведен на орбиту в сентябре 2016 года в рамках миссии по сближению и сбору образцов с поверхности астероида Бенну (1999 RQ36). В недавнем прошлом его считали одной из главных космических угроз для существования жизни на нашей планете. Зонд достиг небесного тела в начале декабря 2018 года и тогда же передал на Землю первые фотографии астероида.

Оказалось, что по форме и окраске Бенну очень похож на еще одно небесное тело, астероид Рюгю, который японская миссия "Хаябуса-2" изучала на протяжении последних полутора лет. В отличие от сухого и безводного Рюгю, в породах Бенну астрономы нашли рекордные количества воды, что сделало его еще более интересным объектом с точки зрения того, как формировалась Солнечная система.

[свернуть]

Сейчас OSIRIS-REx заканчивает составлять карту поверхности Бенну. После этого ученые выберут место, откуда будет взят образец вещества массой около 60 грамм. Специалисты NASA планируют сделать это ориентировочно в конце августа 2020 года, если этому не помешают булыжники, которые усеивают поверхность Бенну.

После забора грунта OSIRIS-REx должен запустить капсулу с первичной материей Солнечной системы в сторону Земли. Если все пройдет удачно, она упадет на территории американского штата Юта в конце сентября 2023 года.
