The Jool Surveyor continues its tour of the Jool system, flying by Tylo! Hopefully a future pass will provide a little better insight into this moon… this time the probe is just too far away to gather much interesting data! A small maneuver planned in a few days will allow another pass, 50 days from now!
Jool
Year 7, Day 294 (Jool Surveyor Performs Maneuvers to Encounter Tylo!)

The Jool Surveyor’s engines fire, altering the probes course and putting it on a path to encounter Tylo in 23 days!
Year 7, Day 264 (Jool Surveyor Pol Fly-By!)
Jool Surveyor approaches Pol!
Instruments record that Goo Scans are… unusual to say the least. Tentacles grow up from the goo, reaching up, then break off. Bizarre, but fascinating!

As the probe passes over Pol’s highlands, gravity scans indicate multiple layers on the world’s surface.

Electricity this far out is proving to be the mission’s main obstacle, transmissions require a great deal of the craft’s power!

The onboard multi-spectral scanner is also able to get the first close look at the surface! Future passes will hopefully add to the data and help create a full picture of the surface.
In all, a very successful start to the Jool Surveyor mission!
Year 7 Day 246 (Jool Surveyor Enters Jool’s Orbit)
The deep space probe Jool Surveyor 1’s engines fire and the probe enters orbit of Jool! KSEA engineers are hopeful that this probe will be able to conduct a general survey of the entire Joolian system… starting with the outer moon Pol!
Year 7, Day 206 (Jool Surveyor Arrives at Jool!)
The Jool Surveyor arrives in the gravitational influence of Jool! In 40 days the vehicle will circularize its orbit, and begin an exploration of the Jool system!
Year 6, Day 283 (Frontier 5 Laythe, Tylo Encounter!)

The Frontier 5 craft in orbit of Jool is instructed to maneuver so it encounters Laythe! 
If all goes to plan, the probe will soon do a flyby of Laythe… the maneuver should also allow for the closest ever flyby of Jool. Sadly, the scientific equipment on Frontier 5 is quite primitive compared to the gravitational scanners and other equipment on more recent probes, however an analysis of the atmosphere, temperature, and pressure should all be possible. 
Frontier 5 moves closer…

Finally Frontier 5 arrives at its closest point to Jool!
The first photographs of Laythe are transmitted back to Kerbin! The planet looks remarkably similair to Kerbin!
“Oh my – that looks just like Kerbin! Astonishing! In the distance you can see Tylo. Just amazing… I can’t wait to visit!”
-Orlas

Frontier 5 moves in close and closer….

Until finally, the probe drops below 50km… but just barely! The science transmitted on Laythe’s atmosphere is of incredible scientific importance, and has made Laythe one of the most intriguing desitnations for Kerbals in the future!

Finally, Frontier 5 moves on, leaving Jool and it’s amazing moon Laythe for future probes to investigate!
Frontier 5 soars past Tylo, its sensors only able to record some basic temperature and pressure readings in the space near the moon – researching Tylo is a job for a future explorer!
Year 5, Day 332 (Jool Surveyor Launches!)
The Jool Surveyor blasts off, heading to Jool! The trip will take just 1 year and 331 days!
Year 5, Day 92 (New Surveyor Probes Commissioned!)
KSEA commissions the development of several new Surveyor class deep space probes – Neidon Surveyor, Urlum Surveyor, Sarnus Surveyor, and the Jool Surveyor. Like Duna Surveyor, these deep space probes are designed to map the surface of deep space bodies to allow a more scientific approach to exploring space!
Year 3, Day 274 (Frontier 5 heads to Jool!)
Frontier 5’s computer is instructed to commence its burn to Jool! The probe will reach Jool around Year 6, Day 200, after a journey of 2 years and 370 days!
If calculations are right, specifically encounter Jool’s innermost moon, Laythe! After the Laythe flyby, an attempt will be made to circularize orbit in the Joolian system. Having never attempted such a thing, no one knows how it will go down!
Year 3, Day 269 (Frontier 5 Probe to Jool Launches)

Frontier 5 launches! Several of the Frontier Probes have now launched out of ‘order’ – however the numbers of the Frontier Probe missions match with construction, not launch date. Frontier 5’s mission to Jool will start in just 4 days!
