Launch services for small satellites

Your payload in orbit, on schedule.

Aphelion flies satellites from 1 to 300 kg to low Earth orbit on a published monthly manifest. See your price range now, hold a slot this week, and plan your mission around a date that holds.

Next rideshare: APH-07 Kestrel, no earlier than 14 Nov 2026 (fictional) Scroll to run the countdown

Launch sequence Simulated

A simulated count from T minus 10 seconds through liftoff and stage separation. Scrolling advances the sequence.

Drag to orbit

Released at the altitude you booked.

The fairing opens once the second stage reaches your target orbit. Your satellite leaves the dispenser, separation is confirmed on telemetry, and your operations team receives the first orbit data.

Liftoff from Pad 2

  1. T+00:00

    Liftoff

    The vehicle clears the tower and rolls onto its southbound heading for a polar orbit.

    0 km, 0.00 km/s
  2. T+01:04

    Max-Q

    Peak aerodynamic load on the vehicle. Thrust is eased back through it, then restored.

    12 km, 0.46 km/s
  3. T+02:30

    Stage separation

    The first stage shuts down and drops away. The second stage engine lights for the climb to orbit.

    74 km, 2.31 km/s
  4. T+03:10

    Fairing separation

    Above the dense atmosphere the fairing halves open and fall away. Your payload is exposed for the first time.

    118 km, 2.95 km/s
  5. T+08:40

    Second-stage cutoff

    The stage coasts on a 210 by 550 km transfer orbit toward the release point.

    210 km, 7.88 km/s
  6. T+54:10

    Circularization burn

    A short burn at the high point of the transfer orbit rounds it out at your target altitude.

    550 km, 7.59 km/s
  7. T+55:00

    Payload separation

    Your satellite is released. Separation confirmation and orbit data go straight to your team.

    550 km, 7.59 km/s

Two ways to fly.

Share a rocket and pay for the mass you fly, or book the whole vehicle and choose the orbit and the date.

Gold: your satellite. Blue: other payloads on the same flight.

Rideshare

Your satellite flies with others to a shared orbit. You pay for your mass, not the rocket.

Mass per slot
1 to 200 kg
Orbits
Sun-synchronous 500 to 600 km, or mid-inclination 45° to 53°
Schedule
Monthly manifest. Your slot is held from the day you sign.
Illustrative rate
$6,500 per kg plus a $40,000 integration fee

Gold: your orbit. Dashed: other orbits you could choose.

Dedicated

The whole vehicle flies for you. You set the altitude, the inclination and the launch window.

Capacity
Up to 300 kg to 550 km sun-synchronous
Orbit
Any altitude and inclination the vehicle can reach
Schedule
You choose the launch window
Illustrative price
$7.5M per vehicle plus $150,000 mission integration

Reserve a payload slot.

Send the mass, the orbit and the month you need. We hold the slot and reply with a draft launch agreement within two business days.

Holding a slot is free until an agreement is signed. This is a concept site, so the form does not send anything.
