The original Explorer was the first Deep Space Vehicle constructed by the KSEA. While it was ultimately a flawed design in many respects, it was the start of the Explorer program to explore the solar system! The next true DSV was DSV-2 Discovery, the test bed for a truly reusable interplanetary space ship. Most of Discovery’s systems were implemented in the Horizon Class Deep Space Vehicle, named after DSV-3 Horizon – Horizon Class ships have become the workhorses of the Kerbal Space Program and comprise the bulk of the DSV Fleet! The Kerbal States now has four Deep Space Vehicles and will soon be adding a fifth!
Honoring the legacy of the DSV program, the next DSV will be named Explorer, and retain the DSV-1 number, but with an “A” indicating it’s the second ship to bear the name! Construction has already begun – and the next mission has already been chosen – a journey to Sarnus!
After an extended stay on the surface Mitster and Kimmy double check the science equipment on the surface of Eeloo is functional and blast off for orbit!
“All systems nominal, orbital velocity and trajectory tracks good…”
-Mitster
“Systems look good! No scientific equipment problems!”
-Kimmy
Mitster rendezvouses with Horizon!
“Looking good! Horizon is ready to dock!”
-Chrisnic
Very slowly, the lander moves in to dock with the interplanetary spacecraft!
As the lander is being left behind on Eeloo orbit, Mitster docks with the front docking port, as maneuvers are more complicated when entering the DDV cargo bay!
“Docking complete! Looks like a good seal!”
-Mitster
“Let’s start moving over all the scientific data and samples! We can still do a lot of science from orbit as well, before we leave!”
After weeks in orbit calibrating equipment and scouting out a new landing site, Mission Control gives the OK to land on Eeloo! Mitster and Kimmy board the lander and undock from Horizon’s payload bay!
“Good morning! Let’s get the systems ready for the approach to Slate!”
-Chrisnic, Mission Engineer
The crew rushes to the bridge – when Mitster spots Sarnus!
“Get a picture Kimmy!” -Mitster
“Wow! That’s the first picture Kerbals have ever taken of Sarnus!” -Kimmy
“…and look how small the sun looks from out here – wow!” -Kimmy
The crew starts powering up systems and verifies full communication with the Kerbin Deep Space Relay Network! After a time delay, a message comes back from Kerbin!
“Horizon – this is Gene at Mission Control, back on Kerbin! We’re reading your transmissions loud and clear – good luck!” -Gene, at Mission Control
The Horizon speeds toward Sarnus…
…and arrives at it’s close approach to Slate, the large moon of Sarnus!
“Main engine … firing! Reactor is showing full power!” -Chrisnic
The capture burn into orbit lasts nearly 2 minutes!
Finally, the ship is captured into orbit of Slate!
“Looks like we’ve got orbit! Good work everyone! Time to disconnect the communications probe!” -Mitster
The probe drifts away from DSV-3 Horizon! The satellite arrays should provide full communication with Kerbin for missions!
As horizon orbits around Slate, the crew starts reviewing data from the orbital insertion, as well as collecting tons of new data from the Sarnusian moon!
Horizon’s cargo bay opens, and the science equipment on the lander starts collecting data! However, Kimmy is the first to crunch the numbers and has some bad news!
“Uh oh! It looks like Slate is much more massive than we thought… this data says that we’re dealing with a lot more gravity than the lander was designed for!” -Kimmy
The crew discusses the situation with Mission Control, and a novel solution is found – change the mission parameters to land on the smaller Sarnusian moon of Eeloo!
“No problem – we can transit to Eeloo in 5 days! Plugging in the maneuver!” -Mitster
Before departing, Horizon collects information over many biomes as it circles the moon – Kimmy even climbs out and conducts visual surveys for several full orbits!
5 days later, on Day 89, Horizon begins it’s maneuver to Eeloo!
The nuclear engine fires…
… and the Horizon is propelled away from Slate, toward Eeloo!
Another 5 days later on Day 94, Horizon circularizes it’s orbit around Eeloo!
“Looks like orbit has been achieved! Eeloo is pretty similar to Mun – just a bit bigger – our lander shouldn’t have an problems!”
-Chrisnic
“We just need to find a good landing site. Maybe we can repurpose one of the survey sattelites in orbit of Slate? They should have enough deltaV to make it here!” -Kimmy
Mission Control agrees, and scientists begin working on maneuvers to bring the Slate Surveyor to Eeloo!
Sarnus Station is finally complete, and it’s rolled out just in time to launch on the first day of Year 22!
“What a fun way to start the new year!” -Samner, Viewing the launch from Mission Control
The Nova Rocket, KSEA’s most powerful heavy lifter, carries the station into space!
Most Kerbals around the Space Center will typically stop what they’re working on, and gather to watch Nova launches – the massive rockets are quite the sight to see, and launch very rarely!
The second stage separates, as the first stage heads back to a fiery reentry into Kerbin’s oceans! At a 2000 km apogee, the station circularizes!
“We’re showing all systems nominal. Let’s send the signal to start up the reactor.” -Gene, at Mission Control
The nuclear reactor starts up – and the boards all show green!
“Reactor at full output – I think we’re OK to go!” -Glenica, at the Science Station at Mission Control
The DSV-class engine fires… and alarm bells go off!
“That thing isn’t getting enough cooling! Let’s power it down to 50 percent power… otherwise it might explode!” -Glenica
The engine is cooled down, but engineers start scratching notes in their design books for the next Sarnus-bound rocket to use this design!
Sarnus Station speeds toward Sarnus… it will arrive in just over 3 years! Once in orbit, crews from visiting DSV’s will have a home to rest at when exploring around Sarnus!
“These nuclear engines have really opened up the solar system to exploration – a trip to Sarnus in just 3 years! Who would have thought it possible!” -Edan
Blueprints have been released for Sarnus Station, a new deep space research station to be placed in orbit of Sarnus! The station will be launched aboard one of the ultra-heavy Nova Rockets, and carried to Sarnus by a modified DSV class nuclear drive! Once at Sarnus the same nuclear reactor will provide the station with ongoing power. The new Life Support Cargo Modules add a significant amount of mass to the station, however they will hold up to 60 years of life support materials for a crew of 3!
“This is the first step to letting us conduct serious investigation of the Sarnus planetary system! Future expansions will eventually grow the station, and it may even be moved into a different orbit, depending on what we need in future years!” -Gene, at Mission Control
The new Sarnus/Slate Relay-Scanner probe arrives at the Sarnus system!
“We still have communication! All those communications dishes really do add up to create a better connection with Kerbin!” -Gene, at Mission Control
The Slate Probe performs an orbital capture maneuver…
… then captures into a 65 degree inclination Slate Orbit!
“We have enough deltaV to maneuver the probe again if need be – but good work everybody! This is our first probe around Slate!
Indeed, previous probes to the Sarnus system have all failed – either not enough power, or not enough communications capacity. This time – it looks like a proper scan of Slate can be completed!
The lens protector on the surface telescope opens!
“We’re recieving signal! We should have a complete scan of the surface just in time for the Horizon to arrive!” -Gene
The Relay-Scan probe continues it’s orbit around Slate! In 106 days it will be joined in the Sarnus system by DSV-3 Horizon!
Aurora 23 launches from Cape Kerman, carrying Mitster, Chrisnic, and Kimmy!
Once in out of the atmosphere, the protective fairing deploys, and the spacecraft starts burning to rendezvous with DSV-3 Horizon!
“There it is! Slowing us down to stationkeeping….” -Mitster
Once Aurora 23 has matched speeds exactly with Horizon, Mitster heads over to the Slate Lander!
“I’m outside the lander… it looks in good shape! So does the relay satellite we’ll be leaving in a wide orbit of Slate!” -Mitster
As the sun sets, Mitster climbs into the lander, detaches from Aurora 23, and moves closer to Horizon’s docking bay!
“This is going to be almost entirely by instruments… it’s dark in space!” -Mitster
Thankfully, Mitster is able to dock with Horizon… just as the sun comes up!
Shortly after that, Mission Control remotely pilots the Relay Satellite over to the nose of Horizon!
“OK —- powering up the basic systems… things seem good over here! I think you guys can come over to Horizon now!” -Mitster
First, Mitster EVA’s over…
…then Kimmy!
“Oh wow! Horizon is looking good! I can’t wait to wake up and be in orbit of Sarnus!” -Kimmy
Chrisnic does a full survey of Horizon to make sure every single component of the mission is ship-shape!
“OK – Horizon is OK to go! Powering up reactor…. Radiator systems are functioning… Main Engine is showing full power available! We’re good Mitster…. light that candle!” -Chrisnic
With that, Horizon’s massive engine fires, in a burn that lasts for several minutes, propelling the crew to Sarnus in just three years!
“Hold on tight everyone… once the burn is done, we’ll head to the cryo-section for a little space nap… and before you know it, we’ll be at Sarnus!” -Kimmy
