Characteristics of the moons of Saturn

Saturn has 62 natural satellites. Here are some features of some of its moons, with mountains, valleys, and striking marks on their surfaces, often marked by asteroid bombardments causing small, huge craters.

Iapetus -  Equatorial ridge

Iapetus’s equatorial ridge was discovered when the Cassini spacecraft imaged Iapetus on 31 December 2004. Peaks in the ridge rise more than 20 km above the surrounding plains, making them some of the tallest mountains in the Solar System. The ridge forms a complex system including isolated peaks, segments of more than 200 km and sections with three near parallel ridges. 

Tethys - Odysseus crater

Odysseus is the largest crater on Saturn’s moon Tethys. It is 445 km across, more than 2/5 of the moon’s diameter, and is one of the largest craters in the Solar System.

Tethys - Ithaca Chasma

Ithaca Chasma is a valley (graben) on Saturn’s moon Tethys, named after the island of Ithaca, in Greece. It is up to 100 km wide, 3 to 5 km deep and 2,000 km long, running approximately three-quarters of the way around Tethys’ circumference, making it one of the longer valleys in the Solar System. Ithaca Chasma is approximately concentric with Odysseus crater. 

Tethys - Red arcs

Unusual arc-shaped, reddish streaks cut across the surface of Saturn’s ice-rich moon Tethys in this enhanced-color mosaic. The red streaks are narrow, curved lines on the moon’s surface, only a few miles (or kilometers) wide but several hundred miles (or kilometers) long.

Rhea - Inktomi crater

Inktomi, also known as The Splat, is a prominent rayed impact crater 47.2 kilometres (29.3 mi) in diameter located in the southern hemisphere of Saturn’s moon Rhea.

Mimas - Herschel Crater

Herschel is a huge crater in the leading hemisphere of the Saturnian moon Mimas, on the equator at 100° longitude. It is so large that astronomers have expressed surprise that Mimas was not shattered by the impact that caused it. It measures 139 kilometres (86 miles) across, almost one third the diameter of Mimas. If there were a crater of an equivalent scale on Earth it would be over 4,000 km (2,500 mi) in diameter – wider than Canada – with walls over 200 km (120 mi) high.

Enceladus - Surface with fractures

Close up of one of the ‘tiger stripes” or fissures called Baghdad Sulcus. Both heat and occasional geysers issue from this formidable crack. Some of the material coating the landscape may be snow condensed from vapor. This closeup of the surface of Enceladus on November 21, 2009, viewed from approximately 1,260 miles (2,028 kilometers) away. 

Dione - Contrasts

This image from NASA’s Cassini spacecraft shows a part of Dione’s surface that is covered by linear, curving features, called chasmata. One possibility is that this stress pattern may be related to Dione’s orbital evolution and the effect of tidal stresses over time. This view looks toward the trailing hemisphere of Dione.

Queens Park Savannah. Port of Spain. Trinidad and Tobago.

The Queen’s Park Savannah is Port of Spain’s largest open recreational space. Covered with low grass, the 3. 5 km (2 miles) perimeter of the Savannah, as it is called by locals, is lined with large beautiful samaan and poui trees. Originally part of the St. Ann’s Sugar Estate, the Savannah, now owned by the state, is Port of Spain’s main outdoor recreational park. On weekends and week day afternoons, the Savannah comes to life and is the destination for sports enthusiasts, health fanatics, joggers, family picnics, strolling couples and persons seeking to indulge in the sumptuous local street food served by vendors.

ONE HARRY, TWO HARRYS, THREE HARRYS, FOUR — When collectors of Native American artifacts are attacked by a meta named Mina Chayton (guest star Chelsea Kurtz) who can bring inanimate objects to life, Barry (Grant Gustin) turns to a surprising ally for help. Determined to crack the identity of The Thinker, Harry (Tom Cavanagh) enlists Cisco’s (Carlos Valdes) help to summon the ultimate think tank: “The Council of Wells’,” a roundtable of the brightest Harrison Wells’ from various Earths “

ZodSqd during recent patrol in full CBRN protective state. 

This video material shows some of the camouflage effects of the Zodiak protective ensemble and it’s olive colour. 

 After carefully checking the area intended for a short in-mission rest, ZodSqd performs a quick hydration from his carry-on water reservoir through his gas mask adapter. 

This video was taken after about 30 minutes in CBRN protective posture. In fact there were another 3.5 km to pass on the imposed patrol route and finally another 60 minutes inside the hermetically sealed Zodiak suit. At this point of the mission a first hydration was useful. This and the relatively moderate autumn temperatures helped the operator to conduct the rest of his patrol without major recreational stops.

The place where my heart is/// ASTRAKHAN, RUSSIA

i don’t own any of these photos. all the credits go to those who do!

Feeling a bit nostalgic tonight. So here’s my blogpost about the best city I have ever visited.

I’m not going to copy paste the history of the city from wikipedia - you can do it yourself :) I’ll just share my emotions and may be a few stories about Astrakhan.

I’ve been visiting Astrakhan as long as I can remember. The smell of junk food in the compartment sleeper, heartwarming conversations with strangers and breathtaking views out of the train’s windows - fields, old cottages, small towns, scarlet sunsets and semi desert steppes. I remember all of these since I was little and  it really has sunk into my mind. The most wonderful feeling I have when I observe the sunset and see how it gets dark, I see stars and small bright lights somewhere in the distance. I start to think about all these people out there - how do they live in such a place? Are they happy? Do they have cows or horses? I like to dream and imagine about their lives. 

Even my way to this city is always exciting so how can I subside my delight about the city itself? 

There is always hot weather and I like it very much. I like that nights are so warm in july you can wear just a summer dress. I like that Volga is near the city and you can have a swim anytime you like. There you can buy fresh fruit, vegetables and berries and be a happy little person you are. But above all, I like how multicultural this city is. I have russian, kazakh, tatar friends there! And they all live in peace. They celebrate together, they laugh together, they grieve together. I hardly face such a thing in Moscow(there everyone is a little xenophobic).

Now we’ve reached my fav part of the blogpost! I want to talk about the countryside where I spend most of my time in Astrakhan. The picture above shows the view in about 3-5 km from my village. My village is a wonderful little world. Everyone know each other, they help each other and have fun together. I have the best friends there. Tanya lives there as well ;) They’re so…simple, easy going people. This country has some hope if such people are still born and raised. It’s hard to put my admiration into words. I live my life there. I walk miles and miles around the village, I cycle, I run through the fields, I sing as loud as I can! I hug, I smile, I love! I cook, I cherish and I feel happy. Boy, I’m tearing up a little ;) 

The place where my heart truly is. My soul belongs there. See you soon…

Day 119 / April 24, 2015

Sorry for my absences this week. it’s midterm exam time again, and i have finals at the end of next month >.> but here’s a quick rundown of my activity the last few days:

Monday was a 5 km, 3 laps (1.5 km, approx) around the trails

Tuesday was a lazy day because my foot was acting up :(

Wednesday I did good… 2.5 laps on the figure 8 circuit (just under 3 km per lap) for 8 km

Thursday I had to work, but I walked both ways again and got some excercise in there :)

I also made some freaking delicious energy bars on wednesday, using seeds and nuts and agave syrup/honey. I have chia seed and mocha, almond and coconut and peanut butter and chocolate… they’re like KIND bars, except I made them at about 1/5 of the cost and more protein/fibre and micronutrients per bar :)

So what happens when she saunters up to the entrance of President Obama's summit? Is it an event anyone can attend? Is she going to surprise Harry again? Will the crowds part so she can do the looong slow walk up to where PH is speaking at the podium? I said before IG they needed a 5 km (3 mile) radius protection order. Maybe this time they'll listen to me. ; )

Secret service, RPO’s are you threatening him?  Who are you?

Caro Firewalker, ho ricominciato a fare sport in modo un po' più serio del divano. Nuoto in una squadra master 2/3 volte a settimana per diaciamo a regime una 3.5/4 di km ad allenamento. C'è gente di tutte le età dai 30 ai 90 anni. L'allenatore, ragazzo giovane, ha detto che abbiamo uno sconto su certi integratori e consiglia amminoacidi ramificati, un beverone di sali e carboidrati ed eventualmente proteine per integrazione. - continua -

- continuazione - Ora, quando da ragazzino nuotavo seriamente tutti i giorni 2,5 ore per 6-7 km il massimo dell'integrazione alimentare ad una dieta cmq equilibrata era un cucchiaino di pappa reale il giorno della gara o al più le vescichette di miele. Ho 34 anni, discretamente in forma, alimentazione direi bilanciata anche se non maniacale… ma davvero mi serve “integrare”? chè a me prendere roba in pillole fa sempre un po’ strano.


no, non ti serve. Considera che tra i miei pazienti ho un ragazzo nuotatore agonista (roba da due allenamenti al giorno per un totale di… boh, non mi ricordo quante decine di ore settimanali) e non ho dato nulla nemmeno a lui. Ovviamente per lui la situazione potrebbe cambiare: è un atleta e potrebbe avere più necessità di quante siano fisicamente raggiungibili con il cibo, ma per quel che mi descrivi tu… bevi un bicchiere di latte a fine allenamento e va benissimo così.

Shipwreck of the Gratitude on Macquarie Island. Photographed by Frank Hurley in 1911. During the first Australasian Antarctic Expedition in Antarctica. .


Macquarie Island is a large island in the Southern Ocean. It is about 1,500 km (932 mi) south east of Tasmania, and about half way between Australia and Antarctica. The island became a UNESCO World Heritage Site in 1992. Macquarie Island is about 34 km (21 mi) long and 5 km (3 mi) wide. It was first discovered in July 1810, by Captain Hasselburgh, who was searching for places to hunt whales and seals. No people live there now. The only way to get to the island is by sea and there are no harbors to dock a ship.

Solar System: 10 Things to Know This Week

Real-life space travel across the solar system’s vast expanse is not for the impatient – it can take many years to reach a destination. The positive side is that our hardy robots are well engineered to take the abuse that the harsh space environment dishes out. This means they can return good science over the course of many years, sometimes for decades.

This week, we take a look at a few of our longest-lived planetary missions. All of them have been returning deep space dispatches to Earth for more than five years. Combined, their flight time adds up to more than a century and a half. The legacy of their exploration is likely to endure even longer.

1. Lunar Reconnaissance Orbiter (LRO) - Launched June 18, 2009

LRO captures crystal-clear views of the lunar landscape on almost a daily basis – and has been doing it for years. Thanks to LRO, we’ve nearly mapped the entire surface now at very high resolution. Learn more about LRO HERE.

2. Dawn – Launched Sept. 27, 2007

The Dawn mission has been exploring the dwarf planet Ceres for just over a year now — but the Dawn spacecraft’s journey began long before that. After a trek from Earth to the asteroid belt, it made a stop at the giant asteroid Vesta before moving on to Ceres.

3. New Horizons – Launched Jan. 19, 2006

With its ongoing discoveries based on the July 2015 Pluto flyby, the New Horizons mission is in the news all the time. It’s easy to forget the mission is not new — the spacecraft has been traversing the dark of space for more than a decade. New Horizons is now more than 3 billion miles (5 billion km) from Earth as it delves deeper into the outer solar system.

4. Mars Reconnaissance Orbiter (MRO) – Launched Aug. 12, 2005

MRO recently marked a decade of returning spectacular images from Mars, in many more colors than just red. Peruse 10 years of MRO discoveries at Mars HERE.

5. Cassini – Launched Oct. 15, 1997

As it circles through the Saturn system, the Cassini spacecraft is currently about 975 million miles (1.57 billion km) from Earth, but its total odometer reads much more than that. This long, spectacular mission is slated to end next year. In the meantime, it’s about to enter the “Grande Finale” stage.

Pyramid-Like Mountain Discovered on Ceres

New NASA images from the Dawn spacecraft have found that there’s a 5 km (3-mile) high mountain rising from the otherwise relatively smooth surface of Ceres.

The dwarf planet continues to rack up the mysteries as the white spots in the images grow larger with Dawn’s gradual descent and evidence of geological activities like landslides and flows are evident.
