Launching Net Captures Orbital Space Debris
https://blog.adafruit.com/2018/09/26/launching-net-captures-orbital-space-debris/

via MOTHERBOARD

On Sunday, the University of Surrey’s Space Center made history when it successfully captured a piece of space junk in orbit. It is the first time an active debris removal system has ever been demonstrated in space.

The test was carried about by the RemoveDEBRIS satellite, an experimental space debris removal platform built by an international consortium of space companies and university research centers. There are tens of thousands of pieces of fast-moving space junk in orbit, which range from the centimeter-scale all the way to entire rocket stages. Some of these pieces are moving faster than a bullet and all of them pose a serious danger to other satellites and crewed capsules.

Ultrasound Patch Can Measure Blood Pressure Deep Inside Body #WearableWednesday
https://blog.adafruit.com/2018/09/26/ultrasound-patch-can-measure-blood-pressure-deep-inside-body-wearablewednesday/

via Wearable Technology

Scientists at the University of California San Diego created a new wearable ultrasound patch that non-invasively monitors blood pressure in arteries deep beneath the skin such as the jugular vein and carotid artery. The new patch could be helpful in detecting cardiovascular problems earlier on and with greater precision. In a proof-of-concept study, the patch performed as well as some invasive means to measure central blood pressure.

Kitty Yeung’s Made of Mars #WearableWednesday #CircuitPlaygroundExpress
https://blog.adafruit.com/2018/09/26/kitty-yeungs-made-of-mars-wearablewednesday-circuitplaygroundexpress/

Very cool project from Kitty Young on Hackster.io:

This project began as a design challenge when my friend, J.R. Skok (a planetary geologist at the SETI Institute), provided me a bunch of basaltic fabrics to make something fashionable. These fabrics were made of volcanic lava, which were mined, melted, pulled into threads and woven into fabrics. Basalt is the most common rock on Mars but is also found throughout the Earth in places like Hawaii and Iceland and on the volcanoes of most continents. Designing with fabrics made from volcanoes on Earth is a fascinating connection to our planet and a critical step toward learning how to build on other worlds. J.R. has been working with these fabrics for their potential to be made wherever basalt is common, but other fabrics are rare. Maybe one day when humans visit Mars, we’ll be using items made of these rocks.

While I was trying to master constructions using these fabrics, I couldn’t help but thinking when and why we would ever want to visit Mars. Apart from our scientific curiosity and exploration, could it be caused by in-habitability of the Earth environment? Thus, I embedded an optical dust sensor from DFRobot and used the temperature sensor on Adafruit Circuit Playground Express in the hope to make us be more aware of air pollution and global warming.

Hispanic Heritage Teacher Resources #HispanicHeritageMonth
https://blog.adafruit.com/2018/09/26/hispanic-heritage-teacher-resources-hispanicheritagemonth/

If you are a teacher or educator and are looking for ways to incorporate Hispanic Heritage Month into your curriculum The National Park Service has some great resources. There are complete Lesson plans and helpful links:

The National Register’s Teaching With Historic Places Lesson Plans along with resources offered by parks for teachers offer a wide array of resources of teachers and educators to learn more about Hispanic heritage in the United States.

October 9th Is Ada Lovelace Day – Spread the Word! #ALD18 @findingada
https://blog.adafruit.com/2018/09/26/october-9th-is-ada-lovelace-day-spread-the-word-ald18-findingada/

The second Tuesday of October is Ada Lovelace. Here at Adafruit ALD has a special significance, each year we spend the day highlighting a number of women who are pioneering their fields and inspiring women of all ages to make their voices heard.

Check back here on October 9 to get some inspirational stories of women in STEM and remember Ada Lovelace.

Finding Ada has some ways you can get involved and spread the word:

One of the most important things you can do to support Ada Lovelace Day is to help us spread the word. Here are some ideas to get you started:

Send a Tweet
Update Facebook
Add a link to FindingAda.com on LinkedIn
Write about Ada Lovelace Day on your blog
Email your friends and/or relevant mailing lists
Post an item on LinkedIn or Facebook Groups

Mapping NYC’s The Things Network with the Manhattan Mapper Build | #IoT #IoTuesday #LoRaWAN @thethingsntwrk
https://blog.adafruit.com/2018/09/25/mapping-nycs-the-things-network-with-the-manhattan-mapper-build/

Really rad project by Frank Leon Rose over at thethings.nyc:

The ManhattanMapper is a custom built mapping device used to measure network coverage from a car driving around New York City. It was constructed using Adafruit Feather boards with software written for the Arduino framework. The following describes the process of building the device and discusses the hardware and software involved.

The Things Network New York is one of 600 communities around the world collaborating to build a free and open LoRaWAN network that is owned and operated by its users. The first city covered by TTN was Amsterdam – it took 10 gateways to establish complete network coverage. With a city as large, dense, and tall as New York, it will take a few hundred gateways. How many will it take, exactly? We don’t know. Therefore, the process is going to be iterative – we deploy some gateways, measure the coverage, plan how to most efficiently fill in the gaps, and repeat.

Right now (June 2018) there are fewer than 20 gateways deployed around the city, many without rooftop antennas. Any new gateway not immediately next to an existing one will expand the coverage significantly.
