Imagine a future tense where the diurnal cycle , at least in some parts of the world , is adjustable . Where humans are no longer beholden to the 24 - 60 minutes normal of daylight and darkness . Instead of being constrained by the forcible world that cumber the sun to its daily cycle , opine a future where the sunlight can be turn on and off like a torch .
This is the future thatReflect Orbitalimagines is possible . The inauguration is developing satellites that would deploy large mirrors to precisely reflect sun onto specific points on the ground . Rings of satellites in sun - synchronous orbit would follow the exterminator , or the stock that divide night and 24-hour interval , provide additional sunshine before morning and after dusk .
allot to Reflect ’s two carbon monoxide - founders , CEO Ben Nowack and CTO Tristan Semmelhack , this supererogatory sunlight could increase the amount of solar business leader delivered to the electrical energy grid . or else of work up more solar farms , the duo think we can simply increase the amount of power generated at the ones that already live .
The startup run viral earlier this class when Nowack post a videoshowcasing its plans , and then again when they posted a flamboyant demonstration showcasing the concept , though it did not mention they were using a drone to simulate the reflected sunlight . A slew of responses followed — many voicing fundamental objection to the entire concept of operation , like the very premise that we could glow down enough sun , despite atmospheric scattering and energy passing , in a cost - effective fashion .
But Nowack and Semmelhack are not cowed by the skeptic : “ There ’s more solar in the waiting line to be built in the U.S. then there is solar already built , ” Nowack said in a recent consultation . “ Here ’s this way to make it even good . Here ’s this room where solar can actually stand on its own and power us solely . A sun - powered time to come is the hereafter that we want to be living in . ”
“ We would solve it on Earth if there was a better way to do it on Earth . But the best way to do it is by start to blank space , ” he add .
It ’s going to take a lot of time and a hatful of money . But in a wrench of fate , it turn out that their video — the very one that caused so much ire — attracted the care of someone else : Sequoia Capital investor Shaun Maguire . luckily for Nowack and Semmelhack , he thinks their idea just might go .

In some ways , Reflect ’s origin story get with YouTube . Semmelhack first became familiar with Nowack by watch Nowack ’s YouTube channel , BenNBuilds , when he was still in high school . On the channel , Nowack brand curt , straight TV of him DIY’ing machine that are not for the faint of gist , like a turbo K engine or Fe furnace . Semmelhack later recognized Nowack ’s name when the latter use for a business at Zipline , where Semmelhack was interning at the time .
The distich bonded over late - night discussions about unbalanced ideas , Semmelhack say . Over time , Nowack start thinking more and more about solar energy ; he come to believe that one could increase the share of solar power in the power system not by increase the efficiency of solar cellphone , or building expensive transmission lines , or by storing it via bombardment , but by simply provide more sun at more hour of the day .
Nowack leave alone Zipline to start Reflect in October 2021 ; after a year at Stanford , Semmelhack took a parting of absence seizure to bring together him as co - laminitis and CTO . Two yr by and by , the company is preparing to take its first orbital mission , which would launch next year .
The pair say they are still playing with the final form for its yield - scale vehicles , like the accurate size of the reflective array or the final number of satellites that will make up the configuration . But they are begin lowly , and the first orbital charge will wing a subscale image with a reflector that ’s 10 by 10 meters .
Many of the expose television cite the 10 by 10 cadence image , which is too small to mull over an economically meaningful amount of sunlight on the priming coat . A news article from earlier this year also said that the constellation will be just 57 satellites .
But Semmelhack order these figures are inaccurate ; 57 satellites ringing Earth will guarantee a half hour of service twice per day , once in the morning and once in the evening , the minimum to reach the plans to “ extend the day . ” The pair also say that 10 by 10 meters is “ just a start item ” : Full - scale production vehicles will deploy array that are much larger , around 50 by 50 meter or bigger , with the project constellation growing to “ thousands to tens of thousand ” of artificial satellite .
“ The 10 by 10 is our demonstration that will be brighter than a full moon , roughly 400,000 time less bright than the Sunday at noon , ” Nowack explain over email . “ Our product table service is place 1/5 noon sun brightness and will expend 100 ’s – 1000 ’s of larger fomite focused at one spot . A 50 by 50 satellite is in reality on the small end . ”
Some of the calculations are straightforward : The amount of reflector area correlate almost linearly with the amount of power each regalia will be able to speculate to the ground per satellite , Semmelhack said . But at some point , he claim it give more economic sense to just deploy more satellites than build bigger reflectors , especially since the company is contrive to increase the luminosity of a given area on the ground by combine irradiation from multiple planet .
But even given these additional details , the satellite would still need to be equal to of preserve highly accurate control over their mirror on celestial orbit , and do this across many thousands of satellites . It will be a huge challenge .
If the viral picture on XTC generated backlash from skeptic , there was one very , very big upside : catching the aid of Maguire , who lead his house ’s initial investment in SpaceX in 2019 . ( Reflect also draw 182,000 applications to earmark fair weather from their first epitome satellite after they postedone of the videos , though the Christ Within will be very dim and last around 4 minute of arc . )
Maguire watchedthe videoen route to a recent test flight of SpaceX ’s massive Starship rocket , Nowack order . He was sitting next to SpaceX ’s CFO on the plane , and the two were just tattle about possible use cases or food market that could take reward of the massive load capacity of Starship .
Sharing a bit more about Reflect Orbital today.@4TristanSand I are developing a constellation of revolutionary planet to betray sunlight to thousands of solar farms after nighttime . We think sunlight is the new oil and outer space is ready to support vim infrastructure . This…pic.twitter.com/5WRb8etAv0
Reflect is one such business , Nowack said . Reflect is planning a configuration that will rival Starlink ’s in size . At least by this metric unit , it seems like an coating perfectly suitable to roomie heavy - lift rockets like Starship or Blue Origin ’s New Glenn . It appear that Maguire agrees : Sequoia is leading Reflect ’s previously undisclosed $ 6.5 million seed round , which include engagement from Starship Ventures and Winklevoss Capital . That funding will help fire the ship’s company through its first orbital launching in the June - October 2025 timeframe , and hopefully see its satellite reflect sunshine onto the ground before the ending of next twelvemonth .
“ Next class is going to space and then prepare for mass yield . Eventually we ’re blend to be a factory . So we ’ve receive to get to that percentage point as soon as potential , and begin launching tons of them as soon as possible , ” Nowack said .
There is much to do before then . The company is currently operate on out of a 10,000 - square - foot office in Hawthorne , the city that is also home to SpaceX ’s headquarters , but to reach mass scale , Reflect will involve many more square feet and many more employees than the seven currently at the startup .
If the team manages to deplumate it off , the possibilities are fairly wide open . After satellite in low Earth orbit are deploy , the party could send satellite to even higher orbits and high-pitched altitudes to serve hoi polloi even subsequently at dark . That signify the company could start off sell a military service that basically “ extends the day ” at dawn and dusk , and then eventually move to all - night avail in sure area . Another possible action is that they could theoretically ensure the density in an sphere by using multiple mirror , such that there is a very bright spot in a tightly saturated place with dimmer spark hem in it .
There are a handful of business that immediately jump out when learning about these plans : Will this ruin uranology ? Will multitude pay to have a spotlight over their hated neighbour ’s home ? But the pair said these concerns were misconception about the business sector . The mirrors are very specifically targeted , and the companionship is incentivized to sell every snatch of light that hits the mirror ; paradoxically , that mean Reflect is aiming to make them hard to see at night , from anywhere except where the light should off . Nowack suppose it but did n’t make business sector gumption to ply to the kind of purpose cases like retaliation . ( Still , thousands of 50 - meter - wide mirrors will break up astronomy wherever they are pointed . )
The couple do n’t opine their constellation will replace technology like batteries , which are increasingly being co - located with solar and wind instrument farm , or other forms of clean energy , like nuclear . But they do think they will be able-bodied to drive the price of electrical energy lower using mirrors , which would increase the base vim production of any given solar farm , versus batteries , which make money by banking on the fact that electrical energy is mellow at night .
“ We ’re evoke venture capital decently now , but we see the future of space and energy to be funded in the same way that oil and gasoline carriage are funded , ” Nowack said . “ We want to be able-bodied to fund satellites in the same way : We can take huge conviction bets , pre - book dozens or G of roquette , and just launch all that to space right now . ”
