California startup Reflect Orbital received clearance to launch its first satellite, aiming to build a constellation to illuminate dark areas with in-space mirrors.<\/p>\n

The Federal Communications Commission (FCC) granted approval for the launch of Reflect Orbital\u2019s prototype satellite, which will test the ability to reflect sunlight down to Earth after dark. The satellite is set to launch to low Earth orbit later this year, where it is designed to deploy a 59-foot (18-meter) film reflector.<\/p>\n

If proven successful, Reflect Orbital has plans to deploy up to 50,000 in-space mirrors mounted on satellites to create sunlight after dark. Its proposed constellation raises concerns over disrupting astronomers\u2019 views of the cosmos.<\/p>\n

Sunlight after dark<\/h2>\n

The California-based startup applied to launch a 59-foot-long (18-meter-long) prototype satellite named Earendil-1 to test its idea: bouncing sunlight off a mirror and reflecting it onto a designated area.<\/p>\n

Through its proposed constellation, Reflect Orbital envisions being able to\u00a0illuminate areas up to 3 miles (5 kilometers) at a time with intensities ranging between 0.8 and 2.3 lux. By comparison, a full Moon provides an illumination of around 0.05 to 0.3 lux on a clear night.<\/p>\n

Why, you might ask? Well, the company wants to use its technology to illuminate disaster zones and search-and-rescue missions, extend working hours for industrial sites, boost agricultural yields and extend cycles, reduce light pollution by replacing city lights, and provide light for defense operations, according to Reflect Orbital\u2019s website.<\/p>\n

Orbital disruption<\/h2>\n

Ahead of the launch of its first satellite, Reflect Orbital\u2019s proposed constellation has already drawn criticism from astronomers who fear the in-space mirrors will impact their ability to capture the night skies.<\/p>\n

The European Southern Observatory (ESO) released a recent report that measured the extent to which bright constellations, such as the one proposed by Reflect Orbital, would affect ground-based observations. The report found that the full fleet of Reflect Orbital\u2019s satellites, when illuminated by the Sun, would lead to the loss of every image from a camera like that of the Rubin Observatory.<\/p>\n

DarkSky International also issued a statement\u00a0in response to the proposed constellation, advocating for \u201ctransparency, environmental review, and public accountability before any such systems are approved or deployed.\u201d<\/p>\n

Reflect Orbital stated that the company is a member of the International Astronomical Union\u2019s Centre for the Protection of the Dark and Quiet Sky and works closely with astronomers to mitigate the effects of its satellites. The company claims that it will \u201csystematically avoid redirecting light near observatories,\u201d Reflect Orbital wrote in an emailed statement.<\/p>\n

\u201cOur satellites\u2019 default will be \u201coff\u201d and we will retain full control to turn them off, dim the light and relocate the spot at any stage,\u201d the company wrote. \u201cEvery spot of light we deliver will be requested, approved and contained. We will only provide redirected sunlight when it is signed off by the appropriate authorities in the relevant jurisdiction.\u201d<\/p>\n

In response to Reflect Orbital\u2019s application, the FCC stated that concerns over the impact of E\u00e4rendil-1 on astronomy were out of its jurisdiction and \u201care not a basis for denial of or additional conditions on Reflect Orbital\u2019s operations.\u201d<\/p>\n<\/div>\n<\/article>\n
