** Look Back at Earth with NASA Astronaut Andrew Morgan

On Friday, April 6, 2020, NASA Astronaut Andrew Morgan began his day by taking a peaceful look back at our planet, out of the International Space Station’s cupola. The cupola serves as a place for astronauts to gaze back at Earth, and take photographs as a part of the Crew Earth Observations investigation. Images like the ones Morgan is taking here, can help us monitor how our planet is changing over time, and inform important scientific research. https://go.nasa.gov/2Vk48xC

A Pictorial & Verbal History of the Space Station

Make your own LEctenna like that used on the ISS to demo power-beaming

The Naval Research Lab (NRL) sent a simple device to the International Space Station (ISS) to demonstrate the reception of a Wi-FI signal and converting it to enough power to light up a LED: NRL power-beaming demonstrated on International Space Station – Naval Research Laboratory (NRL)

International Space Station astronaut Jessica Meir completed the first U.S. Naval Research Laboratory power-beaming demonstration [see video below] in orbit February 12, 2020, using relatively simple components suitable for STEM activities.

Meir showed how NRL’s LEctenna™, a light-emitting rectifying antenna, converted a wireless network signal, similar to home networks, into electric power. While the current generated and light emitted was a small amount, the setup proved the concept in space.

“While this is a cool device on its own, our collaborators [at NRL] have begun investigating the wide range of possible applications for this technology in the real world,” Meir said. “We could find ways to wirelessly charge our mobile devices or remotely power drones. But one of the most interesting applications that they’re looking into is space-based solar panel arrays.”

Led by electronics engineer Paul Jaffe, researchers at NRL are investigating space solar and power beaming as a potential source of clean energy for a variety of military and civilian applications.

Space solar is simply using solar panels in space to harvest the sun’s energy, where collecting rays would be unaffected by clouds or other interference. Power beaming would send the collected energy down to Earth, where it would be converted back – just like LEctenna™ did – to usable energy.

“Some people might know about power beaming, such as for their toothbrush, or putting their phones on a charging pad,” Jaffe said. “What’s really exciting about it though, is that power can be sent wirelessly over much larger distances.”

“NASA astronaut Jessica Meir demonstrates how the LEctenna™, a light-emitting rectifying antenna constructed by the U.S. Naval Research Laboratory, converts electromagnetic waves into electric current on the International Space Station. Similar technology could be used on the Earth’s surface to convert electromagnetic waves beamed from space-based solar arrays.” Credits NASA via NRL

The LEctenna™ demonstration proved the concept of power beaming in space, but was primarily a STEM project to inspire the next generation of innovators launched by the Department of Defense Space Test Program mission. Its simple, relatively low-cost design to convert electromagnetic waves to electric power can be replicated by students.

“LEctenna™ was a cool demonstration to raise awareness,” said Elias Wilcoski, an NRL research physicist. “We want to show students that this is technology that they can do themselves. If we can get them excited about it and space solar and power beaming, we can help bring more scientists and engineers into the fields to ensure the viability of our future.”

Here is a brief tutorial on making your own LEctenna:

Want to be able to see invisible electromagnetic waves? It’s easy to make your own LEctenna in just a few minutes to allow you to do just that! NRL’s Elias Wilcoski shows you how.

** Astronaut Moments: Chris Cassidy – NASA Johnson

Life on board the International Space Station may not be exactly what you’re imagining. But as he heads back for his third mission, astronaut Chris Cassidy says he’ll be savoring every minute of it.

 

** Expedition 63 Docking and Hatch Open – April 9, 2020 – NASA

Expedition 63 Soyuz Commander Anatoly Ivanishin of Roscosmos and Flight Engineers Ivan Vagner of Roscosmos and Chris Cassidy of NASA arrived at the International Space Station April 9, docking their spacecraft to the Poisk module on the Russian segment of the complex. They completed the six-hour journey after launching earlier in the day in their Soyuz MS-16 spacecraft from the Baikonur Cosmodrome in Kazakhstan. A few hours after docking, Ivanishin, Vagner and Cassidy opened hatches between the spacecraft and were greeted by station Commander Oleg Skripochka of Roscosmos and Flight Engineers Jessica Meir and Andrew Morgan of NASA. As the hatches were opened, the families of the newly arrived crew members and American and Russian space officials viewed the activities from Baikonur and offered their congratulations to the newest residents of the outpost.

** Expedition 62 Crew News Conference – April 10, 2020

Aboard the International Space Station, Expedition 62 Flight Engineers Chris Cassidy, Jessica Meir and Drew Morgan discussed the status of their respective missions on the orbital outpost during an-flight crew news conference April 10. Cassidy arrived at the station April 9 on the Soyuz MS-16 spacecraft with two Russian cosmonauts for a six-and-a-half month mission while Meir and Morgan are preparing to return to Earth on the Soyuz MS-15 spacecraft to wrap up their long duration flights on the complex.

**  NASA Live: Earth Views from the Space Station

Currently, live views from the International Space Station (ISS) are streaming from an external camera mounted on the ISS module called Node 2. Node 2 is located on the forward part of the ISS. The camera is looking forward at an angle so that the International Docking Adapter 2 (IDA2) is visible. If the Node 2 camera is not available due to operational considerations for a longer period of time, a continuous loop of recorded HDEV imagery will be displayed. The loop will have “Previously Recorded” on the image to distinguish it from the live stream from the Node 2 camera. After HDEV stopped sending any data on July 18, 2019, it was declared, on August 22, 2019, to have reached its end of life.
