This Week @ NASA--April 14, 2017

Cassini and the Hubble Space Telescope, two of our long-running missions, are providing new details about the ocean-bearing moons of Jupiter and Saturn. Hubble’s monitoring of plume activity on Europa and Cassini’s long-term investigation of Enceladus are laying the groundwork for our Europa Clipper mission, slated for launch in the 2020s. Also, Shane Kimbrough returns home after 171 days aboard the Space Station, celebrating the first Space Shuttle mission and more!

Ocean Worlds

Our two long-running missions, Cassini and the Hubble Space Telescope,  are providing new details about “ocean worlds,” specifically the moons of Jupiter and Saturn. 

The details – discussed during our April 13 science briefing – included the announcement by the Cassini mission team that a key ingredient for life has been found in the ocean on Saturn’s moon Enceladus. 

Meanwhile, in 2016 Hubble spotted a likely plume erupting from Jupiter’s moon Europa at the same location as one in 2014, reenforcing the notion of liquid water erupting from the moon.

These observations are laying the groundwork for our Europa Clipper mission, planned for launch in the 2020s.

Welcome Home, Shane!

Shane Kimbrough and his Russian colleagues returned home safely after spending 173 days in space during his mission to the International Space Station.

Meet the Next Crew to Launch to the Station

Meanwhile, astronaut Peggy Whitson assumed command of the orbital platform and she and her crew await the next occupants of the station, which is slated to launch April 20.

Student Launch Initiative

We’ve announced the preliminary winner of the 2017 Student Launch Initiative that took place near our Marshall Space Fight Center, The final selection will be announced in May. The students showcased advanced aerospace and engineering skills by launching their respective model rockets to an altitude of one mile, deploying an automated parachute and safely landing them for re-use.

Langley’s New Lab

On April 11, a ground-breaking ceremony took place at our Langley Research Center for the new Systems Measurement Laboratory. The 175,000 square-foot facility will be a world class lab for the research and development of new measurement concepts, technologies and systems that will enable the to meet its missions in space explorations, science and aeronautics.

Yuri’s Night

Space fans celebrated Yuri’s Night on April 12 at the Air and Space Museum and around the world. On April 12, 1961, cosmonaut Yuri Gagrin became the first person to orbit the Earth.

Celebrating the First Space Shuttle Launch

On April 12, 1981, John Young and Bob Crippin launched aboard Space Shuttle Columbia on STS-1 a two-day mission, the first of the Shuttle Program’s 30-year history.

Smell That

I pass by this sign all the time. It’s pretty darn cool

The Last Billboard

A 36-foot-long billboard located at the corner of Highland and Baum in Pittsburgh, Pennsylvania. Every month, a different individual is invited to take over the billboard to broadcast personalized messages, which are spelt out using wooden letters that are changed by hand. 

Black (Hole) Friday!

It’s Black Friday, but for us, it’s the annual Black Hole Friday! Today, we’ll post awesome images and information about black holes.

A black hole is a place in space where gravity pulls so much that even light cannot get out. The gravity is so strong because matter has been squeezed into a tiny space…sort of like all of those shoppers trying to fit into the department stores today.

Because no light can get out, you can’t see black holes with the naked eye. Space telescopes with special tools  help find black holes (sort of how those websites help you find shopping deals).

How big are black holes? Black holes can be large or small…just like the lines in all of the stores today. Scientists think the smallest black holes are as small as just one atom. These black holes are very tiny but have the mass of a large mountain! 

So how do black holes form? Scientists think the smallest black holes formed when the universe began. Stellar black holes are made when the center of a very big star collapses. When this happens, it causes a supernova. 

A supernova is an exploding star that blasts part of its mass into space. 

Supermassive black holes are an altogether different story. Scientists think they were made at the same time as the galaxy they in they reside. Supermassive black holes, with their immense gravitational pull, are notoriously good at clearing out their immediate surroundings by eating nearby objects. When a star passes within a certain distance of a black hole, the stellar material gets stretched and compressed – or “spaghettified” – as the black hole swallows it. A black hole destroying a star, an event astronomers call “stellar tidal disruption,” releases an enormous amount of energy, brightening the surroundings in an event called a flare. In recent years, a few dozen such flares have been discovered.

Then there are ultramassive black holes, which are found in galaxies at the centers of massive galaxy clusters containing huge amounts of hot gas.

That’s how you start the Terminator movies, Keith.
