I Talked About Spaghettification But Someone Did One Better And Made A Dang Cute Comic About It!

Will NASA send astronauts to the moon again or any other planet within the next ten years?

@nasaorion spacecraft will launch on the Space Launch system (the largest spacecraft every built, even bigger than the Saturn V rocket!).  Both are under construction @nasa currently, and this is the spacecraft that will take us beyond the low earth orbit of the International Space Station, whether that be the Moon, Mars, or beyond.  We will conduct test missions with astronauts on Orion in the early 2020s, and a first mission will take us 40,000 miles beyond the Moon!

It’s a long ways down. This is a view from the vantage point of astronaut Shane Kimbrough during his spacewalk last Friday outside the International Space Station. Shane posted this photo and wrote, “ View of our spectacular planet (and my boots) during the #spacewalk yesterday with @Thom_astro.” During the spacewalk with Kimbrough and Thomas Pesquet of ESA, which lasted just over six-and-a-half hours, the two astronauts successfully disconnected cables and electrical connections to prepare for its robotic move Sunday, March 26.

Two astronauts will venture outside the space station again this Thursday, March 30 for the second of three spacewalks. Kimbrough and Flight Engineer Peggy Whitson will begin spacewalk preparation live on NASA Television starting at 6:30 a.m. EST, with activities beginning around 8 a.m. Watch live online here.

The world's oldest story? Astronomers say global myths about 'seven sisters' stars may reach back 100,000 years

In the northern sky in December is a beautiful cluster of stars known as the Pleiades, or the "seven sisters." Look carefully and you will p

Holy shit, this is cool!

So many cultures call the Pleiades some variation of the "seven sisters" despite only having six visible stars. There only appear to be six because two of the stars are so close together as to appear as one.

The myths also mention one sister leaving or hiding to explain why there's only six. And based off observations and measurements, those two that are so close together used to be visibly separate. One literally has moved to hide.

And based off the similarities between the more commonly known Greek myth and the Aboriginal Australian myth, plus some other stuff, this myth could possibly even date back to when humanity still all resided in Africa!

A new study uses data from NASAs Spitzer Space Telescope and four ground-based telescopes to determine the distance from a star to the inner rim of its surrounding protoplanetary disk. Researchers used a method called photo-reverberation, also known as light echoes.

Until I get this show rolling, I’m going to be posting some of the things I’ve collected over the years that might make for interesting things to do podcasts about down the line!

Peak Perseid mornings: August 11, 12, 13 | EarthSky.org

When is the peak of the Perseid meteor shower in 2020? The greatest number of meteors is most likely to fall in the predawn hours on August 12, yet under the light of a wide waning crescent moon.

Where to look, and when.

I mention New Horizons in today’s podcast but here’s some more up-to-date info!

Solar System: Things to Know This Week

Time for a little reconnaissance. 

Our New Horizons spacecraft won’t arrive at its next destination in the distant Kuiper Belt—an object known as 2014 MU69—until New Year’s Day 2019, but researchers are already starting to study its environment thanks to a few rare observational opportunities this summer, including one on July 17. This week, we’re sharing 10 things to know about this exciting mission to a vast region of ancient mini-worlds billions of miles away.

1. First, Some Background 

New Horizons launched on Jan. 19, 2006. It swung past Jupiter for a gravity boost and scientific studies in February 2007, and conducted a six-month reconnaissance flyby study of Pluto and its moons in summer 2015. The mission culminated with the closest approach to Pluto on July 14, 2015. Now, as part of an extended mission, the New Horizons spacecraft is heading farther into the Kuiper Belt.

2. A Kuiper Belt refresher

The Kuiper Belt is a region full of objects presumed to be remnants from the formation of our solar system some 4.6 billion years ago. It includes dwarf planets such as Pluto and is populated with hundreds of thousands of icy bodies larger than 62 miles (100 km) across and an estimated trillion or more comets. The first Kuiper Belt object was discovered in 1992.

3. That’s Pretty Far

When New Horizons flies by MU69 in 2019, it will be the most distant object ever explored by a spacecraft. This ancient Kuiper Belt object is not well understood because it is faint, small, and very far away, located approximately 4.1 billion miles (6.6 billion km) from Earth.

4. Shadow Play 

To study this distant object from Earth, the New Horizons team have used data from the Hubble Space Telescope and the European Space Agency’s Gaia satellite to calculate where MU69 would cast a shadow on Earth’s surface as it passes in front of a star, an event known as an occultation.

5. An International Effort 

One occultation occurred on June 3, 2017. More than 50 mission team members and collaborators set up telescopes across South Africa and Argentina, aiming to catch a two-second glimpse of the object’s shadow as it raced across the Earth. Joining in on the occultation observations were NASA’s Hubble Space Telescope and Gaia, a space observatory of the European Space Agency (ESA).

6. Piecing Together the Puzzle 

Combined, the pre-positioned mobile telescopes captured more than 100,000 images of the occultation star that can be used to assess the Kuiper Belt object’s environment. While MU69 itself eluded direct detection, the June 3 data provided valuable and surprising insights. “These data show that MU69 might not be as dark or as large as some expected,” said occultation team leader Marc Buie, a New Horizons science team member from Southwest Research Institute in Boulder, Colorado.

7. One Major Missing Piece 

Clear detection of MU69 remains elusive. “These [June 3 occultation] results are telling us something really interesting,” said New Horizons Principal Investigator Alan Stern, of the Southwest Research Institute. “The fact that we accomplished the occultation observations from every planned observing site but didn’t detect the object itself likely means that either MU69 is highly reflective and smaller than some expected, or it may be a binary or even a swarm of smaller bodies left from the time when the planets in our solar system formed.”

8. Another Opportunity 

On July 10, the SOFIA team positioned its aircraft in the center of the shadow, pointing its powerful 100-inch (2.5-meter) telescope at MU69 when the object passed in front of the background star. The mission team will now analyze that data over the next few weeks, looking in particular for rings or debris around MU69 that might present problems for New Horizons when the spacecraft flies by in 2019. “This was the most challenging occultation observation because MU69 is so small and so distant,” said Kimberly Ennico Smith, SOFIA project scientist.

9. The Latest 

On July 17, the Hubble Space Telescope will check for debris around MU69 while team members set up another “fence line” of small mobile telescopes along the predicted ground track of the occultation shadow in southern Argentina.

10. Past to Present 

New Horizons has had quite the journey. Check out some of these mission videos for a quick tour of its major accomplishments and what’s next for this impressive spacecraft.

Spacewalk complete and new astronaut record set! Shane Kimbrough and Peggy Whitson of NASA successfully reconnected cables and electrical connections on an adapter-3 that will provide the pressurized interface between the station and the second of two international docking adapters to be delivered to the complex to support the dockings of U.S. commercial crew spacecraft in the future. The duo were also tasked with installing four thermal protection shields on the Tranquility module of the International Space Station.

 Having completed her eighth spacewalk, Whitson now holds the record for the most spacewalks and accumulated time spacewalking by a female astronaut. Spacewalkers have now spent a total of 1,243 hours and 42 minutes outside the station during 199 spacewalks in support of assembly and maintenance of the orbiting laboratory.

 Astronaut Thomas Pesquet of ESA posted this image and wrote, ’ Shane and Peggy on their way to their first #spacewalk tasks.’
