Earendil-1
Launch Date
The world's first commercial space mirror originally targeted April 2026. The date has slipped to mid-2026, with the FCC licence still pending. Here's the full picture.
Founded
Ben Nowack (ex-SpaceX) and Tristan Semmelhack (ex-Zipline, Stanford dropout) found Reflect Orbital in Santa Monica.
Hot Air Balloon Demo
6m² mirror on a balloon at 3km redirects sunlight onto solar panels during twilight. Attracts major VC attention.
$6.5M Seed — Sequoia
Sequoia's first space investment since SpaceX in 2010. Baiju Bhatt participates. Company relocates to Hawthorne, CA.
$20M Series A + Air Force Contract
Lux Capital leads. US Air Force SBIR Phase II $1.25M contract. Total funding: $35.2M. Earendil-1 officially announced.
FCC Application Filed
SAT-LOA-20250701-00129 filed. Launch target stated as April 2026. Comment period opens.
SpaceX Selected
Falcon 9 confirmed for Earendil-1 and a second mission. Launch "no later than 2026."
AAS Petition to Deny
American Astronomical Society files formal petition to deny the FCC application, citing catastrophic interference with federally funded astronomy.
Comment Period Closes
1,800+ public comments filed. DarkSky International classifies Earendil-1 as Risk Group 3 (High Risk). FCC enters evaluation phase.
Original Target Missed
April 2026 passes without launch. FCC decision still pending.
Current Target — Pending FCC
Realistic if FCC approves in coming weeks. Falcon 9 already booked — launch could follow quickly.
The Blocking Factors
FCC LICENCE NOT YET GRANTED
The primary blocker. No US satellite can legally launch without FCC approval. The AAS petition to deny and DarkSky's Risk Group 3 classification have created a substantial regulatory record the FCC must formally address.
1,800+ OPPOSITION COMMENTS
The volume and quality of scientific objection is unusually high for a single-satellite demonstration. The FCC must work through all of them before reaching a decision, with no deadline to do so.
LAUNCH VEHICLE SECURED
SpaceX Falcon 9 already booked. Once FCC approval comes, launch could happen within weeks — this is not a bottleneck.
FULLY FUNDED
The demonstration mission is fully funded per the FCC application. The delay is regulatory, not financial.
What Happens Next
FCC approves: Launch within weeks. Mid-2026 still achievable. Earendil-1 deploys, illuminates ten test locations globally, and Reflect Orbital moves toward commercial constellation planning.
FCC denies: Reflect Orbital appeals in federal court. At minimum a year's delay. Serious impact on Series B fundraising. The programme survives but the timeline shifts significantly.
FCC approves with conditions: The most likely outcome given the current administration's deregulatory posture. Conditions might include observatory exclusion zones, brightness limits during astronomical twilight, and mandatory coordination with dark-sky organisations. Reflect Orbital has indicated willingness to cooperate with astronomers.
