На "Веге" они есть, но итальянцы картинку не показывают. После первого пуска в Интернете были ролики с камер на РН, но потом все были убраны. Напрасно.

Первый эстонский спутник продолжает успешный космический полет

ТАЛЛИН, 14 мая — РИА Новости, Николай Адашкевич. Первый эстонский спутник ESTCube-1, запущеный на орбиту 7 мая с космодрома Куру во Французской Гвиане ракетой-носителем "Вега" Европейского космического агентства, успешно продолжает полет, посылая на Землю сообщения о состоянии электрических систем, бортового компьютера, системы связи и главной системы управления, сообщила во вторник газета Postimees.
По словам члена команды ESTCube-1 докторанта Тартуского университета Михкеля Паюсалу, утром 9 мая спутнику была отправлена первая команда и с тех пор двусторонняя связь проходит успешно. Фотокамера спутника уже сделала первые тестовые фото, тестировано обновление программного обеспечения, система электричества тоже заменена обновленной версией.
"Миссия первого эстонского спутника оказалась успешнее ожидаемого, поскольку все тестируемые системы отлично работают и отвечают на посылаемые команды. Установлена стабильная двусторонняя связь", — сказал Паюсалу, добавив, что спутник продолжает посылать сигнал маячка азбукой морзе, отчеты о том, что сигналы этого маяка были приняты, поступают в Тарту со всех материков, кроме Антарктиды.
Кроме того, самый крупный институт, отслеживающий объекты в космосе, — центр управления противовоздушной обороны NORAD (США) — присвоил спутнику официальный номер в регистре космических кораблей 2013-021C. Мини-спутник весом 1,3 килограмма был разработан и изготовлен эстонскими студентами и преподавателями Тартуского университета.

17 May 2013

Earth watcher Proba-V is in good health following its launch last week. The Vegetation imager has been switched on and the first image has been captured over western France.

The miniature satellite is designed to map land cover and vegetation growth across the entire planet every two days. The data can be used for alerting authorities to crop failures or monitoring the spread of deserts and deforestation.

The satellite's vegetation imager was switched on Wednesday in time to get a glimpse of France's coast along the Bay of Biscay and the lush interior. The data were then sent down to ESA's Redu centre in Belgium.

Launched by a Vega rocket fr om French Guiana in the early hours of 7 May along with two other satellites, Proba-V was the first of the three passengers to be deployed into its Sun-synchronous near-polar orbit at 820 km altitude, just 55 minutes after launch.

The effort to bring the minisatellite to life began immediately – known as the Launch and Early Operations Phase, or LEOP, overseen from Redu, wh ere the satellite is controlled from and monitored during its mission.

"The first LEOP milestone was to check the first signs of life from the satellite as it flew over the ESA ground station at Kourou 40 minutes after separation," explained Karim Mellab, Proba-V Project Manager.

"Then a full telemetry session confirmed the stabilisation of the satellite's attitude, or pointing direction. The onboard computer used 'magnetorquers' – basically magnets interacting with Earth's magnetic field – to control the satellite's attitude and compensate for the spin imparted by the separation.

"Since then, we have been checking the various subsystems one by one, confirming that they have made it through the stress of launch in working order.

"These initial checks are now being followed by a diligent commissioning of every single detail of the overall system platform, instrument and technology demonstration payloads, which will take the next few months."

This will include a careful cross-calibration of the Vegetation imager with the previous generation of the instrument, operating aboard France's Spot-5 satellite, to ensure data compatibility.

Less than a cubic metre in volume, Proba-V is a miniaturised ESA satellite tasked with a full-scale mission: to map land cover and vegetation growth across the entire planet every two days.

Proba-V is flying a lighter but fully functional redesign of the Vegetation imaging instruments previously flown aboard France's full-sized Spot-4 and Spot-5 satellites, which have been observing Earth since 1998.

The minisatellite will provide data to the instrument's worldwide user community of scientists and service providers as soon as its orbital commissioning – including cross-checks with Spot-5's Vegetation instrument – is complete and the mission is turned over from ESA's Directorate of Technical and Quality Management to the Agency's Earth Observation Programme.

13 June 2013

  ESA's Proba-V has become the first satellite to pick up aircraft tracking signals, allowing aircraft across the globe to be followed in flight from space.
 "We have succeeded in proving that these relatively low-powered air traffic control signals can indeed be detected from space as they are, without any need for upgraded aircraft equipment," explained Toni Delovski of the DLR German Aerospace Center, overseeing the experiment.
 "Now we want to go on and check how many aircraft we can actually observe in practice, and which types – different sized aircraft being assigned systems with differing signal strengths.
 "This research opens the way to operational space-based aircraft monitoring in future."

 Launched on 7 May, Proba-V's main task is to map vegetation growth, covering the whole world every two days. But the minisatellite – smaller than a cubic metre – also doubles as a miniature research lab, testing a number of promising technologies in space.
 These 'guest payloads' include an experiment to detect Automatic Dependent Broadcast – Surveillance (ADS-B) signals from aircraft, contributed to the mission by DLR in cooperation with Luxembourg's SES TechCom.
 ADS-B signals are regularly broadcast from equipped aircraft, giving flight information such as speed, position and altitude. All aircraft entering European airspace are envisaged to carry ADS-B in the years ahead.
 
  ADS-B ground systems are currently deployed as an add-on to ground-based radar monitoring for air traffic management.
 "However, for most areas of the world, in particular oceans and remote regions, installing air traffic infrastructure based on radars or ADS-B stations is not economically or technically feasible," Mr Delovski added.
 "Instead, space-based ADS-B monitoring holds a lot of potential in terms of security and safety – including search and rescue for airspace not covered by ground-based surveillance. Filling in these gaps has obvious value.

 "Moreover, it may allow aircraft to traverse regions with decreased separation between them and on more efficient routes, boosting overall traffic capacity while cutting fuel consumption and carbon dioxide emissions."
 "This is another success for ESA's Proba series, dedicated to providing early flight opportunities to promising European technologies," added Frédéric Teston, overseeing the Proba series of satellites as part of ESA's Technology Flight Opportunities Programme.

10 July 2013

The first global map of vegetation from the recently launched Proba-V has been unveiled, demonstrating that the minisatellite is on track to continue a 15-year legacy of global vegetation monitoring from space.

Proba-V is designed to map land cover and vegetation growth across the entire planet every two days. The data can also be used for day-by-day tracking of extreme weather, alerting authorities to crop failures, monitoring inland water resources and tracing the steady spread of deserts and deforestation.

Slightly larger than a washing machine, the miniature satellite was launched from French Guiana in the early hours of 7 May. Just over a week later, its Vegetation imager was switched on in time to capture its first image over France's west coast along the Bay of Biscay.

While still being commissioned, the satellite continued to acquire images that have been stitched together to give us the mission's first, uncalibrated map of global vegetation – unveiled last week at the Probing Vegetation conference in Antwerp, Belgium.

"The results of these weeks of Proba-V commissioning give us confidence that the Vegetation users will not be disappointed and will benefit from the new higher performance Proba-V products," noted Alberto Tobias, Head of ESA's Systems, Software and Technology Department.

The commissioning phase includes a careful cross-calibration of the Vegetation imager with the previous generation of the instrument, operating on France's Spot-5 satellite, to ensure data compatibility.

The Spot-Vegetation mission, flown aboard both the Spot-4 and Spot-5 satellites, marked 15 years of service in May, but will come to an end after Proba-V takes over later this year. Achievements of the Vegetation imaging instruments were also highlighted at the conference.

Proba-V will also bridge the gap in vegetation monitoring between Spot-Vegetation and the future Sentinel-3 mission, being developed for Europe's Global Monitoring for Environment and Security programme.

ESTCube-1 Operating Smoothly, Mission to Start in August

Published: 09.07.2013 10:47

ESTCube-1, the student-built nanosatellite that was launched into space from French Guiana two months ago, is functioning as planned and its Earth-based team is set to begin the "solar sail" experiment in August.

The 10x10x11.35 cm cube, weighing in at 1.048 kg, is currently in polar orbit 650 kilometers above the Earth, with a speed of 7.46 km/s, according to fyysika.err.ee.

Several photographs from the on-board camera have been received. A single photo can take a full day to download.

Meanwhile, programmers continue working to make adjustments to the satellite's communication system. Mart Noorma, one of the project leaders, said the team is very content with the launch because nanosatellites especially tend to have problems with sending electrical signals.

ESTCube-1 aims to test an electric solar wind sail technology developed by Finnish researcher Pekka Janhunen. In August, the cube will be told to roll out long wires that should create an electric field capable of harnessing solar energy as a method for propulsion that researchers hope can be used for high-speed travel of spacecraft in the future.

A sequel to the experiment will be conducted by Finland's first satellite, Aalto-1, which will be launched later this year and whose wires will reach 100 meters in length, 10 times further than those of ESTCube-1.

Обломки российского военного спутника угрожают первому эстонскому спутнику
http://www.interfax.ru/world/news.asp?id=321328

Таллин. 1 августа. INTERFAX.RU - Первый эстонский спутник земли ESTCube-1 может столкнуться с обломками российского военного спутника связи.

В пятницу, как только спутник войдет в зону связи, студенты из Эстонии намерены связаться с ним и надеются, что он ответит. Тишина в эфире будет указывать на космическую катастрофу, сообщила в четверг эстонская газета Ohtuleht.

По ее данным, с создателями спутника связались военные с базы ВВС в Калифорнии и сообщили, что спутнику угрожает столкновение с обломками российского военного спутника. Они будут находиться на расстоянии 200 метров друг от друга. В космическом масштабе такая небольшая дистанция может быть погрешностью измерения, и не исключено столкновение космических объектов.

Студенческий спутник ESTCube-1 был запущен 7 мая этого года и в настоящее время вращается вокруг Земли на высоте 660 километров со скоростью 7,6 км в секунду. Спутник размером 10x10x10 сантиметров предназначен для исследования возможности создания "космического паруса".

И кто же на этот раз этот "российский военный спутник"?
