Miniature satellite reaches orbit. Could CubeSats be the next frontier for NASA?

NASA's tiny satellite, CubeSat, is now orbiting Earth in a preliminary test of the satellite's laser technology.

An Atlas V rocket carrying 13 CubeSats launches from Space Launch Complex-3 on Thursday at Vandenberg Air Force Base, Calif. The payload is for the National Reconnaissance Office as part of its NROL-55 mission, as well as several mini-satellites for the NRO and NASA. The miniature satellites provide a low-cost platform for NASA missions, and provide an inexpensive means to engage students in satellite development, operation, and exploitation.

NASA’s tiny satellite has made it to space.

The space agency confirmed Friday that the Optical Communications and Sensor Demonstration (OCSD) CubeSat spacecraft is now in orbit.

Next, the miniature satellite will demonstrate use of its laser.

The arrival of this CubeSat in space is just the first of two flight demonstrations planned to test the tiny spacecraft. 

“This first OCSD demonstration will be very important,”  said Andres Martinez, deputy program manager for Small Spacecraft Technology at NASA’s Ames Research Center at Moffett Field in a news release.

The most compact object ever to be flown in space, the CubeSat will demonstrate high-speed optical transmission of data from the 6-watt laser mounted on the tiny satellite, sending the data from Earth’s orbit to receptors on the ground.

This test will provide NASA scientists with data to evaluate the precision of the laser. 

Two CubeSats will be launched in the second round of OCSD testing to further evaluate what is learned in the first mission and to test proximity operations.

“Laser communications is very important as it enables the transmission of data from high value science experiments, imaging and other sensors,” said Richard Welle, director of the Microsatellite Systems Department at The Aerospace Corporation.

Each CubeSat is small enough to hold in your hand. Weighing just 5 pounds, the tiny satellite is four inches by four inches by 6.7 inches. The laser is hard-mounted to the miniature spacecraft.

"Technology demonstration missions like OCSD are driving exploration," said Steve Jurczyk, associate administrator for the Space Technology Mission Directorate (STMD) in a news release. "By improving the communication capability of small spacecraft to support data-intensive science missions, OCSD will advance the potential to become a more viable option for mission planners."

But, said Mr. Martinez, “we need to learn how to crawl before we walk.”

OCSD may provide just such technical progress.

“I think the key value of small satellites is the way it encourages very rapid turnover of technology,” said Dr. Welle. “It’s kind of like the electronics revolution where you achieve next generation technology in a few months, instead of years.”

NASA already has big plans for the tiny satellites. The CubeSats could be going to Mars. Once near the Red Planet, the CubeSats would relay data back to Earth.

What is the Monitor difference? Tackling the tough headlines – with humanity. Listening to sources – with respect. Seeing the story that others are missing by reporting what so often gets overlooked: the values that connect us. That’s Monitor reporting – news that changes how you see the world.

Dear Reader,

About a year ago, I happened upon this statement about the Monitor in the Harvard Business Review – under the charming heading of “do things that don’t interest you”:

“Many things that end up” being meaningful, writes social scientist Joseph Grenny, “have come from conference workshops, articles, or online videos that began as a chore and ended with an insight. My work in Kenya, for example, was heavily influenced by a Christian Science Monitor article I had forced myself to read 10 years earlier. Sometimes, we call things ‘boring’ simply because they lie outside the box we are currently in.”

If you were to come up with a punchline to a joke about the Monitor, that would probably be it. We’re seen as being global, fair, insightful, and perhaps a bit too earnest. We’re the bran muffin of journalism.

But you know what? We change lives. And I’m going to argue that we change lives precisely because we force open that too-small box that most human beings think they live in.

The Monitor is a peculiar little publication that’s hard for the world to figure out. We’re run by a church, but we’re not only for church members and we’re not about converting people. We’re known as being fair even as the world becomes as polarized as at any time since the newspaper’s founding in 1908.

We have a mission beyond circulation, we want to bridge divides. We’re about kicking down the door of thought everywhere and saying, “You are bigger and more capable than you realize. And we can prove it.”

If you’re looking for bran muffin journalism, you can subscribe to the Monitor for $15. You’ll get the Monitor Weekly magazine, the Monitor Daily email, and unlimited access to
