Helios Aerospace

A fictional space company in Juno: New Origins dedicated to achieving cheap and reliable space travel for all.

Our mission control, rocket, and ground systems just went through the entire countdown of Tundra for the first time this morning to verify all systems. This test culminated with a successful 30 second static fire of all 7 engines on the booster.

History has been made today as on our very first attempt, a Helios lander launched about @kuiperaerospace ‘s Horizon has flawlessly soft landed near luna’s North Pole! Over its 3 month mission, Helios will conduct many experiments on the surface before shutting down in September.

[Helios Aerospace @Helios_JNO]

Horizon is on the pad preparing to launch our very first Helios lander to luna. The goal of this lander is to scout out potential crewed landing sites and conduct tests to verify the practicality of In-Situ Resource Utilization (ISRU) on the surface of Luna.

25 minutes until launch and me and my co-host, Kaden from @Helios_JNO, are out on the KSV Sparky and ready to cover today's historic launch!

Ultimum: Flying from a spaceport near you as early as this August.

Ultimum will be crucial in our endeavors to put boots on the surface of Luna by the end of the year as part of a joint mission between @Helios_JNO and @kuiperaerospace

[Helios Aerospace @Helios_JNO]

Back to Luna and beyond atop Ultimum!

Since you love Ultimum so much…I thought I’d give a more detailed follow-up with a cool spec sheet. Ultimum will be the key to large scale efforts outside of Low Droo orbit and I couldn’t be more excited to share it with everyone!

Introducing Barracuda, our first crewed capsule made for sending crew to Low Droo Orbit and our moons!

[Helios Aerospace @Helios_JNO]

@kuiperaerospace To Luna and beyond!

Arctica.
Coming 2027.
Taking droomanity where it has never been before.

Tundra rolls out to the pad ahead of a full wet dress rehearsal in preparation for launch, next time it leaves the launch pad will be under its own power as soon as may 2nd.

[Helios Aerospace @Helios_JNO]

Tundra is targeting may 2nd for its inaugural flight test carrying a mass simulator to verify performance on the rocket. This flight will also include an ocean-landing of tundra's first stage booster to test engine relight performance ahead of a return to launch site next mission

[Helios Aerospace @Helios_JNO]

Tundra Flight 1's booster has been rolled back to the HIF to allow for additional checks to ensure we have the highest chance of success on this mission and to allow @kuiperaerospace 's horizon to have a smooth testing campaign ahead of its earlier launch this month.

[Parker "Stickman" Miller @stickman_miller]

Horizon is at the Site 11 ahead of its Return to Flight. Pre Flight Static Fire today!

[Helios Aerospace @Helios_JNO]

Tundra booster B1002.1 has been rolled out to the launch pad for landing systems testing ahead of final integration with stage 2 and our payload to await flight 1 "It's A Sign Of The Times" later this month.

[Helios Aerospace @Helios_JNO]

Static fire complete! Next up is rollback for flight preparations. https://t.co/Ied9Xwy2jF

[Helios Aerospace @Helios_JNO]

Tundra is currently undergoing propellant load ahead of it's first static fire test. T-20 minutes

[Helios Aerospace @Helios_JNO]

Tundra has rolled out to Site 11 with all 7 Caelum engines installed for preflight testing ahead of launch later this month. Static fire is planned after several successful milestone tests and will occur within the week.

[Helios Aerospace @Helios_JNO]

Tundra will roll out tomorrow morning for preflight testing, updated launch date pending a successful static fire.

[Helios Aerospace @Helios_JNO]

Teams worked around the clock last night to get our first test article complete and testing at our remote site in preparation for Tundra

[Helios Aerospace @Helios_JNO]

Now launching no earlier than March 28th to provide our teams with more time to prepare and test this launch vehicle and have a more successful flight. Primary goal is orbit, with booster landing or splashdown being a secondary goal.
