Solar Orbiter будет проводить наблюдения за Солнцем с дистанции около 60 R, или 0.284 а.е.  Аппарат будет находиться к светилу ближе, чем все предыдущие миссии в истории.

Особое внимание космический зонд уделит солнечному ветру, потоку заряженных частиц, ответственных за полярные сияния.
Согласно проекту, в задачи обсерватории входит сбор достаточного количества данных для прояснения механизмов влияния Солнца на близкое окружение. В частности, ученые рассчитывают получить ответ, как именно Солнце порождает и ускоряет поток заряженных частиц, в котором купаются планеты.

SRI International, working with specialty foundry leader TowerJazz, has delivered the first complementary metal-oxide semiconductor (CMOS) imager engineering units to the Naval Research Laboratory (NRL) for use on the Solar Orbiter Heliospheric Imager (SoloHI) optical telescope. With its large field of view, SoloHI will make high-resolution images of the corona and solar wind and be able to connect remote sensing observations of the corona to the plasma being measured in situ at the spacecraft.
"This first delivery of our SoloHI high-performance CMOS imager technology to NRL for the Solar Orbiter space mission is an important step toward deploying this technology in a wide range of aerospace applications," said Mark Clifton, vice president, Products and Services at SRI International. "TowerJazz's radiation-hardened CMOS image sensor manufacturing process helped us achieve this innovative solution."
The SoloHI imager is a CMOS image sensor (CIS) built using customized 0.18-um CMOS technology. The radiation-hardened 2k x 2k (4-megapixel) CMOS imagers have passed engineering testing by SRI and are now ready for NRL test bed integration. The full-flight SoloHI focal plane will incorporate a mosaic of four imagers providing a 4k x 4k (16-megapixel) format.
The manufacturing platform for the SoloHI CMOS imager is the TowerJazz 0.18-um process running in Newport Beach, California. TowerJazz has been working with SRI for several years to support U.S. government imaging applications by developing custom technology with advanced radiation hardness, optimization for low read-out noise, and tailored for both frontside and backside illumination.

The European Solar Orbiter project has taken another step towards launch-readiness, with Australia's CSIRO delivering the last of the optical filters that the orbiter needs to image the sun.
The filters have to be extremely robust to survive the Orbiter's 10 year mission in space. We had to design them to withstand the forceful vibration of the spacecraft's launch as well as the ongoing intense heat and high energy radiation fr om the sun.
The filters are now in the hands of the Max Planck Institute for Solar Systems Research, lead agency for this instrument, where they will be integrated into the spacecraft.

Solar Orbiter's STM will leave Airbus Defence and Space in UK on 23rd March., to be delivered to IABG, near Munich in Germany, for mechanical testing. This is an important step in the verification phase of the project. Scheduled to be launched in 2018, the Solar Orbiter mission will study in unprecedented detail how our Sun creates and controls the heliosphere, the bubble of space filled with particles and fields in which the Earth orbits.

At the end of this three-month test campaign, the STM will be shipped back to Airbus Defence and Space in Stevenage for the Stood-Off Radiator Assemblies (SORA) to be integrated. Later in the year, it will be shipped again to IABG for thermal testing.

Solar Orbiter launch moved to 2018

ЦитироватьThe launch of Solar Orbiter, an ESA mission to explore the Sun in unprecedented detail, is now planned to take place in October 2018. The launch was previously targeted for July 2017.

"The decision to postpone the launch was taken in order to ensure that all of the spacecraft's scientific goals will be achieved, with all the system's components adequately tested prior to sending the spacecraft to the launch site," said Philippe Kletzkine, ESA's project manager for Solar Orbiter.

"This will allow us to ensure that this complex mission will be able to meet all of its scientific objectives."

Цитировать#3: Good vibes for Solar Orbiter
01 April 2019 13:54
Having successfully completed its thermal-vacuum tests in December, Solar Orbiter has been subjected to a new series of arduous environmental tests at the IABG facility in Ottobrunn, Germany, including intense shaking of the spacecraft to ensure that it will survive the stress of launch.

The year began with alignment checks of all the instruments, thrusters and other critical components on the Solar Orbiter Protoflight Model (PFM). This was done to demonstrate the thermal stability of these sensitive components when exposed to the extreme temperature variations and vacuum conditions of deep space. The checks were passed with flying colours.
The spacecraft, in a stowed configuration as it will be within the shroud of the Atlas V launch vehicle, was then built up into a more complete representation of the flight model, prior to the start of the mechanical vibration test campaign.
Two solar arrays were fitted onto the spacecraft. These have been specially designed to ensure they provide sufficient electrical power and survive the intense solar heat, whilst minimising the influence of stray light and build-up of electrical charge on the platform and instruments during Solar Orbiter's close approaches to the Sun.
The instrument boom, fitted with its full suite of scientific instruments, was also integrated to the spacecraft's platform and further reference alignment measurements were carried out.
Now in its full flight configuration, but with all appendages still stowed, the spacecraft went through a number of pre-vibration manual deployment tests. These will be used as a reference for comparison with the final 'live-fire' deployment tests that will be conducted after the vibration test campaign.

These preliminary tests were completed for the instrument boom and both solar arrays, as well as the high-gain and medium-gain antennas. The manual deployment tests confirmed that no snags could occur during the initial deployment.
Since the various appendages are not designed for deployment under Earth gravity, the procedure required a series of specially designed off-load rigs. These allow near frictionless deployment of the suspended parts, while simulating the weightlessness of space.
To enable each off-load rig to protect the deployable hardware, the spacecraft had to be orientated during each test so that the plane of the deployment was parallel to the ground.
Once the tests were completed, all of the deployed items were re-stowed and small hold-down-and-release devices were attached to them, ready to be fired after completion of the vibration test campaign.
Shaking All Over
The mechanical vibration test phase is designed to confirm and verify the suitability of the spacecraft to survive the lift-off and journey to reach its operational orbits around the Sun. The testing was divided into two parts.
The first of these, the sine vibration test campaign, replicated the powerful thrust of the Atlas V launcher, sudden engine cut-offs and lateral wind shear events throughout the launch and ascent, by mounting the spacecraft on an electro-mechanical shaker.
The sine vibrations were applied separately up to a frequency of 100 Hz in three axes. A series of low-level signature runs was made before and after the main qualifying events, to determine whether the PFM's structural integrity had changed. These proved that the spacecraft was able to survive the heavy shaking to which it was exposed.

This mechanical shaking was followed by acoustic tests, which covered the frequency spectrum from just below 100 Hz all the way up to 8 kHz. The largest excitations in the acoustic chamber existed in the approximate range of 100 to 500 Hz.
A number of tests were undertaken as the acoustic noise pressure was steadily increased toward the final qualification levels required by the Solar Orbiter PFM.
Once the major segments of vibration testing were completed, the electrical health of the spacecraft was checked, in order to confirm survivability of all electrical systems.

After the successful completion of the mechanical vibration tests, the team has re-measured the alignments of all instruments and other critical items. The data demonstrated very good alignment stability, in particular for the remote-sensing optical instruments.
Meanwhile, all the deployable appendages on the spacecraft are being deployed again, using the off-load rigs. This time, however, the various hold-down devices are all being fired to simulate post-launch deployment of both antennas, the solar arrays and the instrument boom. The boom has two phases of deployment, but only the first can be effectively deployed on the ground.
These deployed structures will then be returned to their stowed configuration and the hold-down release mechanisms will be re-commissioned, ready for flight.
A set of measurements of the spacecraft's mass properties in its stowed configuration will also be completed by the end of March. For this, the spacecraft will be mounted on a mass property measurement rig that performs a series of tilt and rotation operations. This determines the inertia, mass and centre of gravity of the spacecraft, characteristics that are important to enable the attitude/orientation control system to control Solar Orbiter's orientation once in space.
Later in the year, a new series of tests is planned to determine the magnetic signature of the spacecraft. These checks will be carried out in a facility that is largely made of non-magnetic materials like wood and aluminium and has a minimum metallic content, enabling the spacecraft's magnetic characteristics to be measured in isolation from external influences.
About Solar Orbiter
Solar Orbiter's mission is to perform unprecedented close-up observations of the Sun. Its unique orbit will allow scientists to study the Sun and its corona in much more detail than previously possible, and to observe specific features for longer periods than can ever be reached by any spacecraft circling the Earth. In addition, Solar Orbiter will measure the solar wind close to the Sun, in an almost pristine state, and provide high-resolution images of the uncharted polar regions of the Sun.
It will carry 10 state-of-the-art instruments. Remote-sensing payloads will perform high-resolution imaging of the Sun's atmosphere – the corona – as well as the solar disk. Other instruments will measure the solar wind and the solar magnetic fields in the vicinity of the orbiter. This will give us unprecedented insight into how our parent star works, and how we can better predict periods of stormy space weather, which are related to coronal mass ejections (CMEs) that the Sun throws our way from time to time.
Scheduled for launch in February 2020, Solar Orbiter will take just under two years to reach its initial operational orbit, taking advantage of gravity-assist flybys of Earth and Venus, and will subsequently enter a highly elliptical orbit around the Sun.
Solar Orbiter is an ESA-led mission with strong NASA participation.

The Solar Orbiter spacecraft is undergoing important pre-launch tests at the IABG National Space Centre in Ottobrunn, Germany, ahead of its launch, scheduled for February 2020.
The mission will study the Sun, but first the spacecraft must pass vibration, acoustic and shock tests. This will ensure the spacecraft can withstand the stresses of lift off and the extreme environments it will encounter while in orbit around the Sun – from the coldness of space, 150 million km away, to temperatures up to 500 ºC reached when it will be a mere 46 million km away, closer than Mercury.
Solar Orbiter is an ESA-led mission with strong NASA participation. The spacecraft was built and is being tested by Airbus.
