Locals in a rural area of California<\/a> were recently startled to see dazzlingly bright light shining down from nearby mountains at night, illuminating a swathe of the desert below.<\/p>\n

Unbeknown to them, the strange nocturnal illumination was the latest step in a company\u2019s plan to erect thousands of giant mirrors in space to reflect sunlight on to the Earth during night-time.<\/p>\n

The night-time light demonstration, near the town of Lone Pine in the Sierra Nevada region, was conducted by a US startup called Reflect Orbital<\/a>, which has an almost sci-fi aim to launch 50,000 satellites into space in the next decade to illuminate parts of the world at night.<\/p>\n

In July, the Federal Communications Commission (FCC) approved<\/a> Reflect Orbital\u2019s proposal to launch an initial demonstration satellite next year, which will orbit the Earth and, via a 59ft-diameter mirror, reflect sunlight in 3-mile-wide beams in strengths from moonlight up to the brightness of the sun at noon.<\/p>\n

The demonstration in California, undertaken earlier this month, showcased what this would look like on the ground, to the bewilderment of locals, one of whom called<\/a> the lights \u201cblinding\u201d. Large mobile lights were erected near Mount Whitney, with Reflect Orbital comparing the radiance to that of a full moon.<\/p>\n

This provided, the company said, a realistic simulation of one of the benefits of this technology: to help search-and-rescue teams and other emergency responders at night. Other planned uses include bathing crops in sunlight, replacing broken streetlights and even providing solar power for military operations, all summoned by the tap of a button on an app.<\/p>\n

\u201cSearch-and-rescue teams are expected to be our first customers, so this was a real-world test conducted alongside teams who would use our technology,\u201d said a spokesperson for Reflect Orbital, which partnered with a local search-and-rescue team for the demonstration.<\/p>\n

\u201cWe\u2019ll keep working closely with local communities and authorities wherever we operate, and are excited to show how this technology can help save lives.\u201d<\/p>\n

A coalition of environmentalists and astronomers are far less excited about Reflect Orbital\u2019s ambitions, however<\/a>. These groups have criticized the company and the FCC for threatening a harmful change to the separation of night and day that will affect everything from people\u2019s sleep to wildlife and the ability to see the stars from Earth.<\/p>\n

\u201cThis is an idiotic project,\u201d said Jan Hasselman, a senior attorney with Earthjustice, an environmental group. \u201cThere are a huge number of unresolved questions and significant potential impacts. Literally all of life on Earth evolved based on the rhythm of day and night and there is a ton of data showing that messing with this is not a good idea.\u201d<\/p>\n

\u201cThere needs to be some sort of discussion and analysis before we grant these people the right to fundamentally alter the night sky,\u201d he added. \u201cThe proposal for 50,000 of these satellite mirrors is crazy and would really end the night sky as we know it.\u201d<\/p>\n

In August, four groups represented by Earthjustice asked the FCC to reconsider its approval<\/a>, citing concerns that opening up the skies to mirrored satellites, which would ascend to about 400 miles (645km) above the Earth\u2019s surface before reflecting light back, would cause a litany of problems.<\/p>\n

Animals such as birds, insects and mammals rely on the reliable change between day and night to feed, shelter and mate, with any change to this being potentially disastrous for some species.<\/p>\n

Astronomers, meanwhile, have complained that this night-time glare would worsen existing light pollution and spur an overall rush to add more satellites to orbit \u2013 Elon Musk\u2019s SpaceX plans to place 1 million celestial datacenters around Earth<\/a> \u2013 that will obscure the stars and cause more space debris that could descend as pollution back to our world.<\/p>\n

There are also concerns that the scrambling of night and day will harm people\u2019s health<\/a> by disrupting their circadian rhythms as they sleep. Looking directly at the unusual glaring sunlight at night would also, much like doing so during a solar eclipse, harm people\u2019s eyes.<\/p>\n

Reflect Orbital has said its technology will actually aid the environment by boosting the energy output of solar panels when sunlight is pointed at them during night-time, thereby reducing reliance on fossil fuels.<\/p>\n

But some climate scientists have warned against meddling with the amount of sun\u2019s energy reaching Earth. Proposals for solar geoengineering<\/a>, in which particles are sprayed into the atmosphere to deflect sunlight away from Earth instead of toward it, have also prompted fierce opposition<\/a>.<\/p>\n

\u201cGlobal warming is happening because the Earth has a radiative imbalance due to the massive amounts of greenhouse gases we\u2019ve dumped into the atmosphere,\u201d said David Ho, a climate scientist at the University of Hawaii.<\/p>\n

\u201cSome people are promoting the already unhinged idea of installing space mirrors facing away from the Earth to reflect the sun\u2019s energy in order to decrease global warming. Imagine wanting to turn those mirrors around so that the Earth gets hotter.\u201d<\/p>\n

Reflect Orbital said it has had \u201csubstantive discussions\u201d with scientists and astronomers on the use of its technology so that areas such as astronomical sites, national parks and other wildlife-rich areas are avoided.<\/p>\n

\u201cWe welcome oversight and want to play a role in shaping it,\u201d a spokesperson said. \u201cWe believe it is our responsibility to work alongside governments, scientists and regulators rather than ahead of them.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"Locals in a rural area of California were recently startled to see dazzlingly bright light shining down from…\n","protected":false},"author":2,"featured_media":814480,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[23],"tags":[90,416,56,54,55],"class_list":["post-814479","post","type-post","status-publish","format-standard","has-post-thumbnail","category-space","tag-science","tag-space","tag-uk","tag-united-kingdom","tag-unitedkingdom"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts\/814479","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/comments?post=814479"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts\/814479\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/media\/814480"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/media?parent=814479"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/categories?post=814479"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/tags?post=814479"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
