PSLV-C38 Successfully Launches 31 Satellites in a Single Flight
ISRO's Polar Satellite Launch Vehicle PSLV-C38 successfully launched the 712 kg Cartosat-2 Series Satellite along with 30 co-passenger satellites today (June 23, 2017) from Satish Dhawan Space Centre SHAR, Sriharikota. This is the thirty ninth consecutively successful mission of PSLV.

PSLV-C38 lifted off at 0929 hrs (9:29 am) IST, as planned, from the First Launch Pad.  After a flight of about 16 minutes, the satellites achieved a polar Sun Synchronous Orbit of 505 km inclined at an angle of 97.44 degree to the equator (very close to the intended orbit) and in the succeeding seven and a half minutes, all the 31 satellites successfully separated from the PSLV in a predetermined sequence beginning with Cartosat-2 series satellite, followed by NIUSAT and 29 customer satellites. The total number of Indian satellites launched by PSLV now stands at 48.

After separation, the two solar arrays of Cartosat-2 series satellite were deployed automatically and ISRO's Telemetry, Tracking and Command Network (ISTRAC) at Bangalore took over the control of the satellite. In the coming days, the satellite will be brought to its final operational configuration following which it will begin to provide various remote sensing services using its panchromatic (black and white) and multispectral (colour) cameras.

One of the 30 co-passenger satellites carried by PSLV-C38 was the 15 kg NIUSAT, a University/Academic Institute satellite from Nurul Islam University, Tamil Nadu, India. The remaining 29 co-passenger satellites carried were international customer satellites from USA (10), United Kingdom (3), Belgium (3),  Italy (3),  Austria (1), Chile (1), Czech Republic (1), Finland (1), France (1), Germany (1), Japan (1), Latvia (1), Lithuania (1) and Slovakia (1).

With today's successful launch, the total number of customer satellites from abroad placed in orbit by India's workhorse launch vehicle PSLV has reached 209.

India's Polar Satellite Launch Vehicle lifted off fr om an island spaceport on the country's east coast Friday morning, quickly climbing into clear skies before navigating around the Island of Sri Lanka in a pre-programmed maneuver and then heading south over the Indian Ocean to drop an international assortment of 31 satellites off in orbit – including the first satellites for Latvia and Slovakia.

The four-stage PSLV lifted off from the First Launch Pad at the Satish Dhawan Space Center at 3:59 UTC under the power of its massive solid-fueled core stage and four boosters. Two more boosters joined in shortly after liftoff while PSLV was still heading south east, initiating a powered turn when the second stage's Vikas engine was burning and the rocket had cleared Sri Lanka.

PSLV dropped its fairing and fired its third stage ahead of a final push into a 500-Kilometer orbit by the rocket's fourth stage that set up for a fast-paced six-minute satellite deployment to send on the way a diverse group of satellites from 2.4 meters to ten centimeters in size.

Leading the way was India's 712-Kilogram CartoSat-2E Earth-Imaging satellite that made its way into orbit as the primary payload of Friday's flight, accompanied by four microsatellites from Japan, India, Italy and Latvia and 26 CubeSats ranging between one and ten Kilograms in mass for a cumulative secondary payload mass of 243 Kilograms.

Friday's launch marked India's fourth of the year, following in the footsteps of the record-setting PSLV mission in February that lifted a total of 104 satellites, the secretive delivery of India's South Asia Sat atop a GSLV Mk.II and the first orbital test flight of the country's most powerful rocket, the GSLV Mk. III just 18 days prior to PSLV's C38 mission – matching the country's previous record for the shortest turnaround time between orbital space shots.

Although Friday's launch did not set a new record, safely deploying 31 satellites into orbit is by no means a trivial task but one the Indian Space Research Organization has taken on to achieve a unique role on the international launch market for large rideshare missions that are among the most cost-effective ways to send a small satellite into orbit.

CartoSat-2E, only identified as a 'CartoSat-2 Series Satellite' by the Indian Space Research Organization, is India's sixth CartoSat Earth-imaging satellite and the third to launch in a period of 12 months, reinforcing the country's Earth-imaging capabilities both for military reconnaissance and civilian applications. Standing 2.4 meters tall, CartoSat-2E hosts a sharply-eyed instrument comprising a 70-centimeter telescope and a pair of detector modules to collect panchromatic black-and-white imagery with a ground resolution of 0.6 meters and multi-band color images at a two-meter resolution.

Per reports, CartoSat-2E will be directly operated by India's defence forces in a program that is designed for dual-use of all its satellites to enable quick-tasking and rapid revisit capability for both, civilian and military users. The last three CartoSat craft went into lower orbits than their predecessors to further boost their image resolution and bring out more detail of features on Earth's surface, whether man made or natural. Specific applications of CartoSat data are found in cartography, urban planning, environmental monitoring, resource management and disaster relief.

Riding shotgun with CartoSat-2E were a total of 30 secondary payloads of fifteen countries with four non-CubeSat small satellites separating after the primary payload followed by a flood of CubeSats. According to information received by the Indian Space Research Organization from the various sensors on the rocket, all payloads were released as planned – though it might take hours for all to check in with ground stations and possibly weeks to work through the cataloging process.

PSLV, India's flagship orbital launch vehicle since the 1990s, enjoyed a smooth 28-hour countdown ahead of a 9:29 a.m. local time liftoff on Friday on its 40th mission.

Burning 1,600 Kilograms of propellant per second, PSLV thundered off powered by its massive solid-fueled third stage and four of its six Solid Rocket Boosters, the other two joining 25 seconds into the flight to increase the rocket's thrust to 803 metric ton-force. As is customary for Sun Synchronous Missions out of Satish Dhawan, PSLV flew a Dogleg Trajectory – initially heading south east to clear the island of Sri Lanka before making a guided turn to fly south west to reach the planned orbital inclination of 97.44 degrees.

The ground-lit boosters burned out at T+50 and dropped away 20 seconds later, followed by the air-lits 92 seconds into the flight after each of the 13-meter long SRBs burned through 12.2 metric tons of propellant. The core stage consumed 138 metric tons of propellants in one minute and 50 seconds when thrust tailed off followed by the pyrotechnic separation of the 20-meter long stage and the ignition of the 81,500-Kilogram-force Vikas engine on the second stage 68 Kilometers in altitude.

PSLV entered closed loop steering during the second stage burn to dynamically adjust its flight profile based on measured navigation data. The two fairing halves dropped away two minutes and 37 seconds into the mission when PSLV had passed 120 Kilometers in altitude and the hypergolic-fueled second stage handed off to PS3 at 261 seconds with the third stage lighting up its solid rocket motor moments later to generate 25 metric tons of thrust for a 113-second burn.

Upon third stage tail-off, the vehicle completed two minutes of coasting before dropping the PS3 and firing up the twin L-2-5 engines of PS4 that fired for 456.4 seconds with a thrust of 1,500 Kilogram-force, burning over two metric tons of self-igniting propellants. Injection was reported to be on target, into an orbit a little over 500 Kilometers in altitude from wh ere CartoSat-2E will maneuver to a precise 505-Kilometer Sun Synchronous Orbit.

Impressive camera views came from the fourth stage as propulsive flight ended and the delicate satellite separation sequence began, starting with CartoSat-2E that was followed in close succession by NIUSAT and CE-Sat 1. The fourth stage then re-oriented for the release of the remaining two micro satellites and 26 CubeSats. Deployment of all 31 satellites was confirmed when the PS4 arrived within range of an Antarctica tracking station, marking another successful day for ISRO.

With the release of its 31 passengers, the PS4 stage headed off on an extended mission of ten orbits or 15 hours to demonstrate it is capable of executing advanced multi-orbit missions.

ISRO carried out its first multi-orbit mission last year and efforts are underway to prove PSLV can deliver satellites to more than two orbits in one go in order to make the launcher even more attractive on the international market that will see quite a number of new vehicles come on line in the coming years, including new additions as well as seasoned pros like Soyuz that are now available for rideshare missions.

Per the extended mission plan, PS4 will complete a pair of six-second main engine firings followed by a longer burn of 40 seconds to deliver detailed performance data with particular focus on the start-up characteristics of the twin engines and propellant management over extended coast phases. The three orbital maneuvers are expected to lower the fourth stage's perigee altitude to around 350 Kilometers.

ЦитироватьISIS Launches 23 CubeSats to low earth orbit on PSLV-C38
Posted on June 23, 2017 | News

Early this morning, a launch vehicle of the Indian Space Research Organisation ISRO has launched a total of 31 satellites into space. The PSLV-C38 launch carried the CartoSat-2E earth observation satellite as its main payload next to a number of small satellites. The Dutch nanosatellite company ISIS – Innovative Solutions In Space (ISISpace) was responsible for manifesting a total of 23 satellites on this particular launch.

Since 2007, ISIS has been carrying out numerous successful launch campaigns for small satellites through its launch services subsidiary Innovative Space Logistics (ISL) and it is one of the leading players in the small satellite launch business. During this ISILaunch19 launch campaign, ISISpace engineers were responsible for the integration of the 20 CubeSats onto the PSLV launch vehicle, using satellite deployer systems and sequencing electronics developed in Delft. In the last couple of weeks an ISISpace team took care of the final integration of all hardware on the launch vehicle at the launch site in India, resulting in the successful launch of this morning.

Launching a record breaking 101 satellites on the PSLV-C37 earlier this year, ISISpace continuous to bolster its launch services track record with this PSLV-C38 launch. Multiple launches to low earth orbit are scheduled for the second half of 2017 across multiple launch vehicles.



Among these 23 satellites, there are 8 CubeSats that will complement and complete the QB50 constellation for upper atmospheric research (www.qb50.eu). This project, sponsored by the European Commision's FP7 is managed by the Von Karmann Institute from Belgium and ISISpace has been one of the consortium partners of QB50 since the start. The CubeSats launched by ISISpace into polar orbit will work together with the CubeSats deployed from the International Space Station in May.

The ISILaunch19 manifest also includes several payloads that were initially scheduled for a launch on a Falcon 9 mission through Spaceflight's Sherpa mission, a launch that was significantly delayed due to various factors. Such a re-manifesting of payloads clearly shows the added value of the ISILaunch Services of ISISpace to serve the CubeSat community, offering access-to-space flexibility towards customers of launch services by operating across multiple launch vehicles and missions in parallel.

ЦитироватьИндия произвела успешный запуск ракеты с 31 спутником
МОСКВА, 23 июн — РИА Новости. Индия в пятницу произвела успешный запуск ракеты-носителя PSLV-C38 с 31 спутником, сообщает Индийская организация космических исследований (ISRO).
Сообщается, что ракета стартовала с космодрома на острове Шрихарикота, Бенгальский залив.
Основным грузом стал индийский спутник Cartosat-2, который весит 712 килограммов и предназначен для наблюдения за поверхностью Земли. Остальные 30 наноспутников в общей сложности весят 243 килограмма, при этом только один из них принадлежит Индии. Остальные 29 принадлежат 14 иностранным государствам: Австрии, Бельгии, Чили, Чехии, Финляндии, Франции, Германии, Италии, Японии, Латвии, Литвы, Словакии, Великобритании и США.
Цитировать"Поздравляю ISRO с сороковым по счету успешным запуском ракеты-носителя Polar c 31 спутником из 15 стран. Мы гордимся вами!" — написал на своей странице в Twitter премьер-министр Индии Нарендра Моди.
В свою очередь Вильнюсский университет сообщил, что с территории Индии в пятницу на орбиту был запущен третий по счету литовский спутник Lituanica SAT-2, созданный учеными вуза совместно с компанией Nano Avionics. В сообщении университета сказано, что литовцы участвуют в проекте QB50, цель которого — запустить в космос ряд небольших спутников. По информации вуза, спутники будут исследовать нижние слои атмосферы. Проектом руководит бельгийский Фон Кармановский институт гидродинамики, над проектом более шести лет работали ученые из 23 стран и 50 университетов.
Как сказал представитель факультета физики Вильнюсского университете Людас Тумонис, запуск нескольких небольших спутников вместо одного большого проводится из-за того, что разряженная в термосфере атмосфера останавливает большие спутники. "Благодаря использованию нескольких десятков небольших спутников в различных точках замеряют различные параметры термосферы. Если один спутник выйдет из строя — миссия сразу завершается, а если выйдут из строя несколько, как я их называю, миниатюрных спутников — мы сможем продолжать исследование. Кстати, все эти спутники вместе взятые стоят как один большой спутник", — приводятся в сообщении слова Тумониса.

ЦитироватьЛитва опробует в космосе экологическое топливо для наноспутников
ВИЛЬНЮС, 23 июня. /Корр. ТАСС Владимир Иванов/. Экологическое топливо для коррекции орбиты наноспутников, разработанное учеными Литвы, будет опробовано на миниатюрном аппарате LituanicaSat-2. Он был запущен в пятницу с помощью индийской ракеты с космодрома Шрихарикота (Индия).
LituanicaSat-2 участвует в международной миссии QB50 по изучению земной термосферы, находящейся на высоте 200-380 км. В проекте задействовано более 30 наноспутников. Однако литовский аппарат примечателен прежде всего тем, что заправлен экологическим топливом. "Конструкторы наноспутников - университеты, малые предприятия - сталкиваются с проблемой топлива для своих аппаратов. Как правило, в космической отрасли используют гидразин - ядовитое, канцерогенное вещество", - отметил руководитель проекта Витянис Бузас. Для заправки двигателей спутника гидразином необходимы дорогостоящая инфраструктура, скафандры.
Литовская экологическая разработка эту проблему снимает. "Наш наноспутник весом 3 кг представляет собой прямоугольник длиной 30 см. Аппарат оснащен ракетным микродвигателем, работающим на так называемом "зеленом" химическом топливе", - рассказал Бузас.
Оснащение микродвигателем позволит Lituanica Sat-2 пробыть на околоземной орбите значительно дольше, чем это удалось двум малым литовским спутникам, запущенным в 2014 году. На орбите они проработали всего по нескольку месяцев. Ожидается, что Lituanica Sat-2 пробудет в космосе до трех лет.

Литва символически вступила в "космический клуб" в феврале 2014 года. На околоземную орбиту тогда с Международной космической станции были выведены два литовских наноспутника - LitSAT-1 и LituanicaSat-1. Каждый из них представлял собой созданный учеными и студентами миниатюрный прибор в виде куба с гранью около 10 см и весом около 1 кг. LitSAT-1 продержался в космосе около трех месяцев, LituanicaSat-1 - более 150 дней. После входа в атмосферу спутники сгорели.

Space debuts

Among the 30 nanosatellites aboard Friday's PSLV-C38 launch are Aalto-1, a Finnish student sat, and D-Sat, a 3U CubeSat developed by D-Orbit of Italy, which will perform a controlled re-entry as part of experiments it hopes could lead to solutions to the growing issue of space debris.

Latvia, Venta-1, and Slovakia, skCube, sent their first satellites into orbit on the launch. A list and breakdown of the satellites can be found on Nasaspaceflight.com.

The others come from countries, including India, France, Germany, Belgium, Austria, US and the UK, with a total mass of 955 kg, including the 700 kg Cartosat-2E.

Cartosat-2E is an advanced remote sensing satellite with a multispectral optical imager and panchromatic camera, which will be used for urban planning, services, infrastructure development, traffic management and disaster management.

In February another Chinese cubesat, Chen Jiayong-1 (aka DIDO-2), was among the record 104 satellites successfully put into orbit by India's PSLV-C37.
