Raczej nie wydaje mi się - kwestia orientacji sondy względem Słońca oraz odpowiedniego wprowadzenia na nową orbitę wydaje się być ważniejsza.

Atlas V wynosi Solar Orbiter

Dziesiątego lutego o godzinie 05:03 CET nastąpił start europejsko-amerykańskiej misji Solar Orbiter. Start nastąpił za pomocą rakiety Altas V z wyrzutni LC-41 na Florydzie. Lot przebiegł prawidłowo i sonda została skierowana na odpowiednią orbitę heliocentryczną. Zgodnie z harmonogramem lotu nastąpiło także rozłożenie paneli słonecznych oraz przesłanie potwierdzenia statusu sondy do centrum kontroli misji.

ULA team completes countdown practice run before Solar Orbiter launch
January 24, 2020 Stephen Clark

United Launch Alliance teams loaded super-cold liquid hydrogen and liquid oxygen into an Atlas 5 rocket Friday at Cape Canaveral during a countdown dress rehearsal for a planned launch next month with the Solar Orbiter mission, a robotic spacecraft to study the origins of the solar wind and image the sun’s poles for the first time.

The Atlas 5’s wet dress rehearsal Friday at Cape Canaveral’s Complex 41 launch pad served as a practice run of the launch day procedures ULA crews will perform during the real countdown.

The wet dress rehearsal is not part of standard Atlas 5 launch campaigns, but NASA requires the extra test for missions that have limited planetary launch windows. Solar Orbiter is such a mission, and has 19 daily launch opportunities next month beginning Feb. 5 to reach a flyby with Venus in December to use the planet’s gravity to slingshot closer to the sun.

Officials have delayed the launch of a United Launch Alliance Atlas 5 rocket with the European-built Solar Orbiter spacecraft from Cape Canaveral by two days to Feb. 7, a ripple effect from time spent fixing a minor issue last week during a launch vehicle countdown dress rehearsal.

The European Space Agency, which leads the Solar Orbiter mission in partnership with NASA, announced the two-day delay to Feb. 7 on Sunday. The new Solar Orbiter launch window opens at 11:15 p.m. EST on Feb. 7 and extends to 1:15 a.m. on Feb. 8 (0415-0615 GMT on Feb. 8). (...)

NASA, Europe space agency launch Solar Orbiter mission
by Paul Brinkmann Washington DC (UPI) Feb 09, 2020

(...) "It's called a hyperbolic escape trajectory," said Scott Messer, program manager for NASA programs at United Launch Alliance. "It actually leaves the gravitational field of the Earth and heads out. It has a couple of gravity assists, a slingshot around Venus, and then it comes back around Earth, and back to Venus."

The reason for the multiple gravity slingshots is that the Solar Orbiter ultimately has to escape the orbital plane of the planets, which circle the sun's equator.

"It's a highly optimized effort that goes on between the spacecraft team and the rocket team. It's a fairly big optimization problem," Messer said. (...)

LIFTOFF FOR SOLAR ORBITER, ESA'S MISSION TO FACE THE SUN UP CLOSE
10 February 2020

(...) "As humans, we have always been familiar with the importance of the Sun to life on Earth, observing it and investigating how it works in detail, but we have also long known it has the potential to disrupt everyday life should we be in the firing line of a powerful solar storm,

"By the end of our Solar Orbiter mission, we will know more about the hidden force responsible for the Sun's changing behaviour and its influence on our home planet than ever before."

"Solar Orbiter is going to do amazing things. Combined with the other recently launched NASA missions to study the Sun, we are gaining unprecedented new knowledge about our star,"
said Thomas Zurbuchen, NASA’s associate administrator for Science at the agency’s headquarters in Washington.

"Together with our European partners, we’re entering a new era of heliophysics that will transform the study of the Sun and help make astronauts safer as they travel on Artemis program missions to the Moon."

At its closest, Solar Orbiter will face the Sun from within the orbit of Mercury, approximately 42 million kilometres from the solar surface. Cutting-edge heatshield technology will ensure the spacecraft's scientific instruments are protected as the heatshield will endure temperatures of up to 500°C – up to 13 times the heat experienced by satellites in Earth orbit.

"After some twenty years since inception, six years of construction, and more than a year of testing, together with our industrial partners we have established new high-temperature technologies and completed the challenge of building a spacecraft that is ready to face the Sun and study it up close," adds César García Marirrodriga, ESA's Solar Orbiter project manager.

Pierwsze spodziewane w historii przejście sondy przez ogon komety za nami.
Trwa oczekiwanie na dane naukowe z tego przelotu


STEREO Watches Comet ATLAS as Solar Orbiter Crosses Its Tail
June 4, 2020

While STEREO recorded this footage, Solar Orbiter crossed one of comet ATLAS’s tails. Launched in February 2020, the spacecraft wasn’t scheduled to enter full science operations until June 15, but engineers adjusted Solar Orbiter’s testing schedule and turned on its four most relevant instruments for the encounter. It’s the first time a comet tail crossing by a spacecraft not designed to chase them was predicted in advance.

As material sheds from a comet’s nucleus, it leaves behind two tails: a thin ion tail, made of charged particles, and a more diffuse dust tail that reflects visible light. The ion tail always points away from the Sun regardless of the comet’s trajectory; the dust tail more closely follows the comet’s path. Solar Orbiter crossed the ion tail on May 31, some 27 million miles downstream and outside STEREO’s field of view. The team is still awaiting those results. It will fly through the remnants of the dust tail on June 6. (...)

Solar Orbiter to pass through the tails of Comet ATLAS
29/05/2020

(...) Serendipitously flying through a comet’s tail is a rare event for a space mission, something scientists know to have happened only six times before for missions that were not specifically chasing comets. All such encounters have been discovered in the spacecraft data after the event. Solar Orbiter’s upcoming crossing is the first to be predicted in advance. (...)

(...) Po starcie sonda została skierowana “ku Słońcu”. Pierwsze zbliżenie do Słońca (peryhelium orbity) nastąpiło 15 czerwca 2020. Wówczas Solar Orbiter znalazł się z odległości 77 milionów kilometrów od naszej Dziennej Gwiazdy. Po przejściu przez peryhelium rozpoczął się okres testowania instrumentów pokładowych sondy. Pierwsze dane z Solar Orbiter zostaną opublikowane przez NASA w połowie lipca. (...)

O różnych technicznych wyzwaniach, z którymi musiał zmierzyć się zespół misji.

Technical challenges of flying close to the Sun

Caveman’s solution

Enbio’s technique, called ‘Co-Blast’, originally developed for medical implants, involves grit-blasting away a metal’s surface oxide layer to chemically bond a new coating onto it. The coating effectively becomes part of the metal, so it never comes off.

The company tested different coatings, notes Enbio’s Managing Director John O’Donoghue: “I recalled cavemen used burnt bone for cave painting, along with charcoal – and its durability is proved by the fact the paintings survive to this day. We found a US company called Ebonex who produce a char bone pigment – they burn the bone in low oxygen, then crush it, so all the fat and tissue is gone. It turned out the pigment already had space heritage, having been employed by NASA.”

“For us, this effectively saved the project,” adds Claudio. “It meant the surface would retain constant ‘thermo-optical properties’ – maintain the same black colour despite years of exposure to extreme ultraviolet radiation – so we keep thermal stability throughout the mission, setting maximum surface temperature at 520 °C and no more.”

Known as ‘Solar Black’, this black coating ended up applied to other Sun-exposed parts of Solar Orbiter, so the spacecraft evolved from a largely white object with a few black surfaces to a largely black object with a few white surfaces.
