ЦитатаNASA's New Planet Hunter: TESS

Опубликовано: 28 мар. 2018 г.

NASA's Transiting Exoplanet Survey Satellite (TESS) will find undiscovered worlds around bright nearby stars, providing targets where future studies will assess their capacity to harbor life. TESS is a NASA Astrophysics Explorer mission, led and operated by MIT and managed by Goddard. With the help of a gravitational assist fr om the Moon, the spacecraft will settle into a 13.7-day orbit around Earth.
 Скрытый текст:
Four wide-field cameras will give TESS a field-of-view that covers 85 percent of the entire sky. Within this vast visual perspective, the sky has been divided into 26 sectors that TESS will observe one by one. The first year of observations will map the 13 sectors encompassing the southern sky, and the second year will map the 13 sectors of the northern sky.

The spacecraft will be looking for a phenomenon known as a transit, wh ere a planet passes in front of its star, causing a periodic and regular dip in the star's brightness. NASA's Kepler spacecraft used the same method to spot more than 2,600 confirmed exoplanets, most of them orbiting faint stars 300 to 3,000 light-years away

TESS will concentrate on stars less than 300 light-years away and 30 to 100 times brighter than Kepler's targets. The brightness of these target stars will allow researchers to use spectroscopy, the study of the absorption and emission of light, to determine a planet's mass, density and atmospheric composition. Water and other key molecules in its atmosphere can give us hints about a planet's capacity to harbor life.

NASA's Transiting Exoplanet Survey Satellite (TESS) is undergoing final preparations in Florida for its April 16 launch to find undiscovered worlds around nearby stars, providing targets where future studies will assess their capacity to harbor life.
 Скрытый текст:
"One of the biggest questions in exoplanet exploration is: If an astronomer finds a planet in a star's habitable zone, will it be interesting fr om a biologist's point of view?" said George Ricker, TESS principal investigator at the Massachusetts Institute of Technology (MIT) Kavli Institute for Astrophysics and Space Research in Cambridge, which is leading the mission. "We expect TESS will discover a number of planets whose atmospheric compositions, which hold potential clues to the presence of life, could be precisely measured by future observers."

On March 15, the spacecraft passed a review that confirmed it was ready for launch. For final launch preparations, the spacecraft will be fueled and encapsulated within the payload fairing of its SpaceX Falcon 9 rocket.

TESS will launch from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida. With the help of a gravitational assist from the Moon, the spacecraft will settle into a 13.7-day orbit around Earth. Sixty days after launch, and following tests of its instruments, the satellite will begin its initial two-year mission.

Four wide-field cameras will give TESS a field-of-view that covers 85 percent of our entire sky. Within this vast visual perspective, the sky has been divided into 26 sectors that TESS will observe one by one. The first year of observations will map the 13 sectors encompassing the southern sky, and the second year will map the 13 sectors of the northern sky.

The spacecraft will be looking for a phenomenon known as a transit, wh ere a planet passes in front of its star, causing a periodic and regular dip in the star's brightness. NASA's Kepler spacecraft used the same method to spot more than 2,600 confirmed exoplanets, most of them orbiting faint stars 300 to 3,000 light-years away

"We learned from Kepler that there are more planets than stars in our sky, and now TESS will open our eyes to the variety of planets around some of the closest stars," said Paul Hertz, Astrophysics Division director at NASA Headquarters. "TESS will cast a wider net than ever before for enigmatic worlds whose properties can be probed by NASA's upcoming James Webb Space Telescope and other missions."

TESS will concentrate on stars less than 300 light-years away and 30 to 100 times brighter than Kepler's targets. The brightness of these target stars will allow researchers to use spectroscopy, the study of the absorption and emission of light, to determine a planet's mass, density and atmospheric composition. Water, and other key molecules, in its atmosphere can give us hints about a planets' capacity to harbor life.

"TESS is opening a door for a whole new kind of study," said Stephen Rinehart, TESS project scientist at NASA's Goddard Space Flight Center in Greenbelt, Maryland, which manages the mission. "We're going to be able study individual planets and start talking about the differences between planets. The targets TESS finds are going to be fantastic subjects for research for decades to come. It's the beginning of a new era of exoplanet research."

Through the TESS Guest Investigator Program, the worldwide scientific community will be able to participate in investigations outside of TESS's core mission, enhancing and maximizing the science return from the mission in areas ranging from exoplanet characterization to stellar astrophysics and solar system science.

"I don't think we know everything TESS is going to accomplish," Rinehart said. "To me, the most exciting part of any mission is the unexpected result, the one that nobody saw coming."

TESS is a NASA Astrophysics Explorer mission led and operated by MIT and managed by Goddard. George Ricker, of MIT's Kavli Institute for Astrophysics and Space Research, serves as principal investigator for the mission. TESS's four wide-field cameras were developed by MIT's Lincoln Laboratory. Additional partners include Orbital ATK, NASA's Ames Research Center, the Harvard-Smithsonian Center for Astrophysics, and the Space Telescope Science Institute. More than a dozen universities, research institutes and observatories worldwide are participants in the mission.

ЦитатаСША намерены 16 апреля вывести на орбиту телескоп для поиска экзопланет
ВАШИНГТОН, 28 марта. /ТАСС/. Американское космическое ведомство - NASA завершает последние приготовления для вывода на орбиту 16 апреля нового телескопа для поиска потенциально пригодных для жизни планет. Об этом сообщил в среду на пресс-конференции в штаб-квартире NASA Джордж Рикер, руководитель группы исследователей из Массачусетского технологического института, которая занимается реализацией данного проекта.
По его словам, специальная комиссия 15 марта подтвердила готовность к запуску аппарата под названием Transiting Exoplanet Survey Satellite (TESS, Спутник по исследованию планет, проходящих перед своей звездой). Для запуска с космодрома на мысе Канаверал (штат Флорида) будет использована ракета-носитель Falcon 9 производства компании SpaceX. Изначально отправка телескопа в космос была запланирована на март этого года.
"Мы ожидаем, что TESS откроет ряд планет, химический состав атмосферы которых может представлять интерес с биологической точки зрения", - отметил Рикер. Как указал, в свою очередь, представитель NASA Стивен Райнхарт, этот телескоп "открывает дверь для исследований на совершенно другом уровне". "Мы сможем изучать отдельные планеты и обсуждать различия между ними. Это новая эра в исследовании экзопланет", - подчеркнул он.
TESS во время своей двухлетней миссии сфокусируется на звездах, находящихся на расстоянии до 300 световых лет от Земли. Предполагается, что телескоп, оснащенный четырьмя широкоугольными камерами, изучит более 200 тыс. звезд с целью выявить на их ярком фоне крохотные пятна, которые могут оказаться планетами. Всего ученые рассчитывают обнаружить несколько тысяч экзопланет.
 Скрытый текст:
В ближайшие 10 лет NASA планирует вывести в космос еще два новых телескопа с целью поиска планетных систем, по своим параметрам в наибольшей степени сравнимых с нашей Солнечной системой. Основываясь на информации, полученной с помощью орбитальной обсерватории Hubble и других телескопов, эксперты NASA ранее высказали предположение, что только в галактике Млечный путь имеется по меньшей мере 11 млрд планет, сравнимых по размеру с Землей. С 1995 года было подтверждено существование 3,5 тыс. экзопланет, на которых потенциально возможна жизнь, и насчитывается еще около четырех тысяч "кандидатов".

ЦитатаNASA Discusses Upcoming Launch of Next Planet Hunter

NASA Video

Опубликовано: 28 мар. 2018 г.

During a press conference at NASA Headquarters in Washington, D.C., astrophysics experts discussed the upcoming launch of NASA's next planet hunter, the Transiting Exoplanet Survey Satellite (TESS).

Scheduled to launch April 16, TESS is expected to find thousands of planets outside our solar system, known as exoplanets, orbiting the nearest and brightest stars in our cosmic neighborhood. Powerful telescopes like NASA's upcoming James Webb Space Telescope can then further study these exoplanets to search for important characteristics, like their atmospheric composition and whether they could support life.
