Earendil-1
Launch Date
Eärendil-1, the world's first commercial space mirror, originally targeted April 2026 and has slipped to later in 2026. The FCC granted the licence on 9 July 2026, clearing the last regulatory gate — a confirmed launch date is now the only thing missing. 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. The FCC would grant approval on 9 July 2026.
Current Target — FCC Approved
FCC approval was granted 9 July 2026 and Falcon 9 is already booked, so launch could follow quickly once a date is set.
The Blocking Factors
FCC LICENCE GRANTED
Granted 9 July 2026. 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 its decision, which it granted on 9 July 2026.
LAUNCH VEHICLE SECURED
SpaceX Falcon 9 already booked. With FCC approval granted (9 July 2026), launch could happen within weeks of a date being set — 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
The FCC gate is cleared. Approval was granted on 9 July 2026 (docket SAT-LOA-20250701-00129). The FCC dismissed the constellation-based objections, reasoning that this licence covers a single, short-duration test satellite rather than the proposed larger fleet. That removes the one hard blocker that had held the launch since the April target slipped.
What is left is timing, not permission. Falcon 9 is already booked, and the FCC granted approval calling the technology “potentially groundbreaking” in the public interest. What remains is Reflect Orbital confirming a specific rideshare slot and completing final integration. Because Falcon 9 rideshare cadence to 88° near-polar orbit runs roughly every couple of months, a slot should not be a long wait once the satellite is flight-ready.
The realistic risk now is slippage, not denial. This launch has already moved from April to “later in 2026,” and deploying a large thin-film mirror is unproven in flight. A further slip toward late 2026 or early 2027 is plausible — not because of regulators, but because novel space hardware tends to take longer than hoped. Reflect also committed to independent impact research and NSF/NASA coordination, which it will carry out alongside launch preparation.
