Oumuamua – What We Are Learning

Remember Oumuamua the interstellar visitor that whizzing through the solar system at over 315,000 km per hour? The thing was kind of strange at first because it wasn’t anywhere near a roundish shape rather it was like a giant spike or chip.

I could imagine this thing being chipped off from a larger object or maybe this was all that was left after such an event. Now there is a new theory and I didn’t see this one coming. Gravity stretching? Yeah, weird. The other thing about Oumuamua is it is giving insight into planetary formation.

Here’s the scoop from NASA – he first interstellar object ever seen in our solar system, named ‘Oumuamua, is giving scientists a fresh perspective on the development of planetary systems. A new study by a team including astrophysicists at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, calculated how this visitor from outside our solar system fits into what we know about how planets, asteroids and comets form.

On Oct. 19, 2017, astronomers working with the NASA-funded Panoramic Survey Telescope and Rapid Response System (Pan-STARRS1) at the University of Hawaii spotted an object zipping through our solar system at a very high speed. Scientists at the Minor Planet Center, funded by NASA’s Near-Earth Object Observations Program, confirmed it was the first object of interstellar origin that we’ve seen. The team dubbed it ‘Oumuamua (pronounced oh-MOO-ah-MOO-ah), which means “a messenger from afar arriving first” in Hawaiian — and it’s already living up to its name.

“This object was likely ejected from a distant star system,” said Elisa Quintana, an astrophysicist at Goddard. “What’s interesting is that just this one object flying by so quickly can help us constrain some of our planet formation models.”

Student Projects Go To Space

Utterly fantastic! It’s a great time to be a student.

NASA – Four university student projects were successfully launched at 6:51:30 a.m. EDT, March 25, 2018, on a NASA suborbital sounding rocket from the agency’s Wallops Flight Facility in Virginia.

The two-stage Terrier-Improved Malemute sounding rocket carried the projects to an altitude of 107 miles. The projects then descended by parachute, landing in the Atlantic Ocean. The projects were recovered and will be returned to the students for analysis.

The undergraduate student teams’ projects from Utah State University, Logan; the University of Nebraska – Lincoln; the University of Kentucky, Lexington; and the Florida Institute of Technology, Melbourne, were launched through the NASA Undergraduate Student Instrument Project or USIP.

“USIP gave students the opportunity to experience working in a research and development environment and learn about different aspects of taking an engineering project from conceptual design through fabrication and testing. Students gained skills in project management, design analysis and selection, fabrication, and assembly. The Nebraska USIP team also honed its interpersonal and writing skills through design reviews, monthly status reports, and required grant reporting,” said Amy Price, a senior mechanical engineering student and team lead.

She said, “The University of Nebraska-Lincoln USIP team is comprised of multidisciplinary students providing a well-rounded project team. Throughout the two-year duration of the USIP project, 29 undergraduate students have worked on the project. This includes students from various disciplines within the College of Engineering such as biological systems, chemical, computer, electrical, and mechanical engineering majors. In addition, there are math, physics, finance, and economics majors on the team.”

“USIP has been a fantastic experience for the more than 46 University of Kentucky students who have been able to work on the project. The KRUPS Operational Re-entry Experimental Vehicle for Extensive Testing has been a great opportunity for participating in the NASA systems engineering process and for obtaining hands-on experience designing, building, integrating and testing the capsule’s ejection mechanism and communication systems. A highlight so far was presenting the project to the NASA Deputy Administrator at the Spring 2018 Space Grant Conference,” said Gabriel Myers, a senior mechanical engineering and physics major.

Myers added, “Through cooperation with engineers at NASA Wallops and elsewhere, the group has been able to gain a degree of engineering intuition aiding the students in drawing connections between their classes and applying that knowledge.”

Wallops managers serve as USIP technical advisors for these four cooperative agreements on behalf agency’s Office of Education and the Science Mission Directorate. In 2016 NASA selected an additional 43 university experiments to fly on orbital and suborbital vehicles including rockets, aircraft, balloons and CubeSats through a cooperative agreement competition for members of NASA’s 52 Space Grant Consortia and other eligible higher education institutions.

Liberty One Launch – A Must See

You may remember hearing about “Mad” Mike Hughes. He was the individual who was going to launch himself in a “Do It Yourself” rocket. Well he did it!

He did get some sort of back injury according to reports. That second parachute maybe ought to have opened a bit sooner.

Reports say he went 1,875 feet into the air trying to prove the Earth is flat? Let’s see 1,875 feet is 571.5 meters, seems like an airplane might be a better choice but hey, what fun would that be – lol.

Hey, if you are trying to prove the Earth is flat you have to do it right. Right = rocket, and how much better can it get than in a home-made rocket? It can’t and my hat is off to Mike and I hope he has a speedy recovery and continues his efforts! He is going to try and get to the 109 km mark in the rocket he is calling the “Rockoon”.

The launch site was about 325 km east of Los Angeles California. The ramp was constructed by the 61 year-old Hughes from an old mobile home and the launch angle was set so he would not land on public land, a serious issue for the US government.

You can see MUCH more about all this at the Noize TV site.

Hey, There’s STEVE

STEVE is spectacular!

Who’s STEVE? STEVE is not a who, rather STEVE is a what. STEVE is short for Strong Thermal Emission Velocity Enhancement.

Part of the story from NASA:

NASA == Notanee Bourassa knew that what he was seeing in the night sky was not normal. Bourassa, an IT technician in Regina, Canada, trekked outside of his home on July 25, 2016, around midnight with his two younger children to show them a beautiful moving light display in the sky — an aurora borealis. He often sky gazes until the early hours of the morning to photograph the aurora with his Nikon camera, but this was his first expedition with his children. When a thin purple ribbon of light appeared and starting glowing, Bourassa immediately snapped pictures until the light particles disappeared 20 minutes later. Having watched the northern lights for almost 30 years since he was a teenager, he knew this wasn’t an aurora. It was something else.

From 2015 to 2016, citizen scientists — people like Bourassa who are excited about a science field but don’t necessarily have a formal educational background — shared 30 reports of these mysterious lights in online forums and with a team of scientists that run a project called Aurorasaurus. The citizen science project, funded by NASA and the National Science Foundation, tracks the aurora borealis through user-submitted reports and tweets.

The Aurorasaurus team, led by Liz MacDonald, a space scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, conferred to determine the identity of this mysterious phenomenon. MacDonald and her colleague Eric Donovan at the University of Calgary in Canada talked with the main contributors of these images, amateur photographers in a Facebook group called Alberta Aurora Chasers, which included Bourassa and lead administrator Chris Ratzlaff. Ratzlaff gave the phenomenon a fun, new name, Steve, and it stuck.

But people still didn’t know what it was.

Scientists’ understanding of Steve changed that night Bourassa snapped his pictures. Bourassa wasn’t the only one observing Steve. Ground-based cameras called all-sky cameras, run by the University of Calgary and University of California, Berkeley, took pictures of large areas of the sky and captured Steve and the auroral display far to the north. From space, ESA’s (the European Space Agency) Swarm satellite just happened to be passing over the exact area at the same time and documented Steve.

For those who might be looking for a launch today, I messed up my calendar and had the wrong date for the launch I referenced yesterday with the Expedition 55 crew is on 21 March. I have corrected the reference to it in a previous post. Where the confusion came in is there is Soyuz Satellite launch (four broadband internet satellites) WAS to have launched tomorrow but that has been delayed until Friday. Whew. . .
