Cosmic detective story time 🕵️‍♂️🕵️‍♀️

Remember that @ESASolarOrbiter movie released yesterday, showing Venus, Earth, & Mars as the spacecraft cruised along last November? 🛰

Turns out there's a fourth planet in there: Uranus 🙂

The tale of how it was spotted is worth telling 👍

@ESASolarOrbiter The original movie, made from 22 hours of images taken by the SoloHI instrument on #SolarOrbiter clearly showed Venus, Earth, & Mars moving against the stellar background as the spacecraft & planets moved on their orbits.


@ESASolarOrbiter The movie was posted in several places, including on the Facebook page of @RAL_Space_STFC, one of @esa's partners in the mission. In a comment on that post, James Thursa posed an interesting question. He asked whether Uranus was also in the image.

22 hours cruising through the Solar System, courtesy of the SoloHI camera on the ESA/NASA #SolarOrbiter 🛰🌞

I’ve annotated the original movie to show Venus, Earth, & Mars, each moving on their own path relative to the Sun, the stars, & the spacecraft.

More info below 👇
Be sure to go & watch the original full-quality movie, free of Twitter's obnoxious compression here. (Be sure to select the 6MB MPG version.)…
FWIW, there are quite a few cosmic rays in the images, seen as flashing pixels. You'll also see a few elongated streaks which you might initially think are meteors, but they're just cosmic rays too, hitting the detector at a grazing angle. Besides, meteors need an atmosphere 😉

For many space missions first data usually comes after 6 months-1 year, but #SolarOrbiter is different: the time between data being received on Earth & it being released is at most 90 days!
#OpenESA #WeAreAllSolarOrbiters
#SolarOrbiter remote sensing instruments will only start nominal operations in Nov ’21, so their data will come later. But we already enjoyed a sneak peek earlier this year:…

Hoy la @esa_es ha hecho públicas las primeras imágenes de alta resolución que la sonda espacial #SolarOrbiter sacó del Sol a 77 millones de kilómetros de distancia el 30 de mayo y lo que han visto los científicos les ha dejado picuetos. ¿Qué han visto? #hilo
A primeros de febrero, como algunos recordaréis, asistí al lanzamiento de la sonda Solar Orbiter (SolO, en clara referencia a Star Wars) en las instalaciones de la Agencia Espacial Europea (ESA, por sus siglas en inglés) en Darmstadt (Alemania) a unos 20 min. a tren de Frankfurt.
Cubrí el evento para la web de la revista National Geographic y escribí este artículo sobre la misión.…

#SolarOrbiter Captures Closest Images of the Sun; Reveals Presence of Millions of 'Campfires'…


By @MrigakshiDixit Image
#NASA and #ESA have released the first images of the Solar Orbiter, including the closest pictures ever taken of the Sun. These images were captured when the spacecraft completed its first close pass of the Sun in mid-June this year
Launched on February 10, 2020, the Solar Orbiter mission has carried several cutting-edge instruments to monitor the environment of the Earth’s closest star.

📷The brand new #SolarOrbiter images that we are going to see today are already the closest ever images of the Sun, captured only 77 million km from our star's surface 👍


📽️Perihelion animation:…
While #SolarOrbiter is taking the closest images of the #Sun, @NASA’s Parker Solar Probe is actually flying much closer. The two missions will work together, collecting complementary data to investigate our nearest star

Launched in February, #SolarOrbiter performed its first close approach to the #Sun in mid June, getting just 77 million km from its surface and capturing the closest ever images of our parent star 🌞🛰️📷

These brand new views will be released tomorrow. Stay tuned #TheSunUpClose Image
An international collaboration between ESA and NASA, #SolarOrbiter lofted to space aboard the US Atlas V 411 rocket from Cape Canaveral, Florida at 05:03 CET on 10 February (23:03 EST on 9 February).

Relive the excitement of the launch:
The mission of #SolarOrbiter: to perform unprecedented close-up observations of the #Sun – including from high latitudes, obtaining views of the Sun's poles – and investigate the Sun-Earth connection.

Are you ready to see #TheSunUpClose?

CALLING ALL MEDIA: We will reveal the first images taken by #SolarOrbiter, only 77 million km from the surface of the #Sun, during an online press briefing on 16 July 14:00 CEST / 13:00 BST.

👉Details + registration:…
“The first images are exceeding our expectations,” says Daniel Müller, ESA #SolarOrbiter Project Scientist. “We can already see hints of very interesting phenomena that we have not been able to observe in detail before.”

Bonus #science opportunity for #SolarOrbiter, which will cross through the tails of #Comet ATLAS in the next few days. The mission's 4 in-situ instruments will be switched on and collecting data during the encounter 👍 #weareallsolarorbiters

More details:…
The commissioning of #SolarOrbiter has been proceeding over the past three months to ensure the spacecraft and instruments will be fully functional for the 1st close pass of the #Sun, to take place on 15 June, around 77 million km from our parent star.
Meanwhile, @einionyn noticed that #SolarOrbiter would pass through the ion tail of Comet ATLAS on 31 May-1 June + through the dust tail on 6 June. Fortuitously, the 4 in-situ instruments that measure the conditions around the spacecraft are also great for studying #comet tails! Image

DÍA 6 - Darmstadt, Frankfurt, Madrid, Bilbao
MARTES 11 DE FEBRERO (Día de la mujer y la niña en la ciencia)
Habitualmente ese día suelo tener preparado algo relacionado con mujeres en ciencia. Este año no ha sido así porque tuve que andar entre aviones de vuelta a casa.
Al final Ciara cesó momentáneamente su actividad, por lo que los vuelos no se vieron cancelados.
Puestos a pagar penalizaciones de vuelos -ya iba dos- elegí el horario que me permitiera salir más tarde y no tener que pegarme la madrugada padre.

DÍA 5 - DARMSTADT - Lunes 10 de febrero de 2020
El gran día, o mejor dicho, la gran madrugada. A las 5.03h si todo iba bien, la sonda #SolarOrbiter despegaría desde Cabo Cañaveral y yo estaba allí para ver qué se vive en un centro de operaciones aerospaciales. #hilo
Caí rendido pasada la medianoche.
Las 3.00 am llegarían demasiado pronto.

First data from #SolarOrbiter science instruments have reached the ground! What did we learn from them? And what's next for our science teams? Check our latest news!… #WeAreAllSolarOrbiters
As the #SolarOrbiter boom was deployed last week, the @SolarOrbiterMAG data first reflected mostly the spacecraft magnetic field, eventually providing a first glimpse of the much weaker field in the surrounding environment 👍 #weareallsolarorbiters

@SolarOrbiterMAG The first #SolarOrbiter Magnetometer measurements of the interplanetary magnetic field, taken after the instrument boom deployment, more than one million km away from Earth, look good 👇 #weareallsolarorbiters

We are now on-site, ready for the @ESASolarOrbiter Atlas V launch. Goodness know how long we have to wait. #SolarOrbiter @Dr_Lucie Image
@Dr_Lucie We are now in the final 14 minute hold before the last four minutes of the countdown commences. The atmosphere* is electric*. [*metaphorically, thank goodness] #SolarOrbiter Image
@Dr_Lucie IT LAUNCHED! It exploded in all of the good ways and none of the bad ways. What a day. We are done. Goodnight! #SolarOrbiter @Dr_Lucie Image

2/19 NASA’s @ParkerSunProbe goes even closer than @ESASolarOrbiter but samples particles, plasma & the solar wind – it doesn’t image the Sun’s surface, only snapping images looking away, while #SolarOrbiter peers forward – the 2 complement each other…
3/19 At its closest to the Sun, @ESASolarOrbiter must withstand sunshine 13 times more intense than Earth orbit. Imagine having to stand out under a cloudless sky filled with 13 separate Suns – the trick is to bring a sunshade with you #SolarOrbiter…
4/19 So @ESASolarOrbiter has taken shape as a largely ‘normal’ spacecraft, because it can take shelter behind an extremely powerful multi-layered heat shield, designed by @Thales_Alenia_S in Italy #SolarOrbiter…
