Here’s looking at you: remote sensing from space

Those eyes in the sky are seeing plenty. Researchers are finding more and more ways to use that data to solve the world’s great challenges and even save lives.

An article in the latest issue of The Scientist detailed several recent projects. Among them:

“With funding from NASA, Frank Muller-Karger, director of the Institute for Marine Remote Sensing at the University of South Florida, and his colleagues purchased more than 1,400 Landsat 7 images acquired between 1999 and 2003 in order to outline and classify the world’s shallow-reef ecosystems. Completed in 2007, the Millennium Coral Reef Mapping Project produced the first uniform map of all the coral reefs around the world at a 30-meter-pixel resolution. The United Nations’ World Conservation Monitoring Centre is now refining the map in order to use it for global conservation efforts.”

The information the team has gathered is also useful for fish and wildlife managers and others with interests in monitoring ocean water quality. Muller-Karger is one of the authors of a paper to be presented next month at SPIE Defense, Security, and Sensing in Baltimore on new products using satellite data for monitoring the Deepwater Horizon oil spill in the Gulf of Mexico in 2010.

A recent article in the SPIE Newsroom detailed another USF team’s work in monitoring the Deepwater spill. See images from their work here:


The Scientist article also describes using tracking of ocean temperatures off the Horn of Africa and of greening vegetation inland that enabled prediction and control of an outbreak of deadly Rift Valley fever in Kenya, Somalia, and Tanznaia; studies of the impact of invasive goats and vegetation on native birds and plants in Hawai’i; and a chance study of ocean grazing halos with valuable applications in managing fish stocks.

There are some common threads throughout these stories. One of them is NASA, in the news this week in connection with a new book by Hayden Planetarium Director Neil deGrasse Tyson, who also is an advisor to NASA and other space organizations, and next year will host the revived television series “Cosmos.”

Tyson wants people in general to get excited about space exploration, and would like to see increased funding for NASA programs along with that. But part of his ultimate goal isn’t about space research in particular. Just as space exploration accelerated science and technological progress during the so-called “space race” of the 1960s, Tyson sees scientific exploration and discovery as the driver for progress in the 21st century.

“The nations that embrace innovation in science and technology are the ones who will lead the world,” he said in an interview posted yesterday in the Cosmic Log. Noting the many spin-offs from spaceflight -- from satellite weather forecasting to to Tang and Teflon -- he said, "Spin-offs are great, but that's not even what I'm talking about. I'm talking about a culture that wants to dream about tomorrow, and make tomorrow happen today.”

And, he noted in an interview on The Daily Show last night, “Scientists and engineers are the ones who enable tomorrow to happen today.”

#FacesofPhotonics: Inspired

Guest blogger: Emily Power is a Winter Quarter graduate in communications from Western Washington University, and most recently social media intern for SPIE, the international society for optics and photonics. She is blogging on responses to the SPIE #FacesofPhotonics campaign, to share the stories of SPIE students around the globe.
It is a commonly known fact: students are the future. Around the world, students with ideas, opinions, and innovative minds are preparing for their opportunities to conceptualize and create the next advances for the ever-changing world in which we live.
In the field of optics and photonics, students are making a difference even now, sharing their work and building their networks through conferences such as SPIE Photonics West, coming up next month in San Francisco.
The SPIE campaign #FacesofPhotonics was developed as a showcase across social media to connect students from SPIE Student Chapters around the world, highlighting similarities, celebrating differ…

Grilling robot takes over backyard barbecue

Photonics has already made profound contributions to such areas as medicine, energy, and communications to make our everyday lives more efficient. (Hence the name of this blog.) People in all walks of life benefit from the incorporation of photonics technologies. We look forward to future advancements when the technology may help find a cure for cancer, monitor and prevent climate change, and pave the way to other advancements we can’t even visualize yet.
But here’s a photonics-based invention -- already demonstrated – that breaks ground in a new area: the backyard barbecue. Talk about hot fun in the summertime!
The BratWurst Bot made its appearance at the Stallwächter-Party of the Baden-Württemberg State Representation in Berlin. It’s made of off-the-shelf robotic components such as the lightweight Universal Robots arm UR-10, a standard parallel gripper (Schunk PG-70) and standard grill tongs. A tablet-based chef’s face interacted with party guests.
Two RGB cameras and a segmentatio…

UPDATE! Gravitational waves ... detected!

Update, 11 February: A hundred years after Einstein predicted them, gravitational waves from a cataclysmic event a billion years ago have been observed.
For the first time, scientists have observed gravitational waves, ripples in the fabric of spacetime arriving at Earth from a cataclysmic event in the distant universe. This confirms a major prediction of Albert Einstein's 1915 general theory of relativity and opens an unprecedented new window to the cosmos.
The discovery was announced on 11 February at a press conference in Washington, DC, hosted by the National Science Foundation, the primary funder of the Laser Interferometer Gravitational Wave Observatory (LIGO).
The gravitational waves were produced during the final fraction of a second of the merger of two black holes to produce a single, more massive spinning black hole. This collision of two black holes had been predicted but never observed.
The event took place on 14 September 2015 at 5:51 a.m. EDT (09:51 UTC) by both of…
