So on the same week that the highly-anticipated film “The Martian” opens in U.S. theaters (you are going to go see it, I assume) NASA revealed the latest discovery regarding the Red Planet: there is water on the surface there, salty rivulets that periodically run down steep slopes in Hale Crater and stain its sands with dark streaks.
It might not be something that Mark Watney would want to guzzle a glassful of, but it is a major finding for planetary scientists!
It’s over halfway through 2015 and perhaps it’s high time for an all-new, updated, knock-your-socks-off “blue marble” photo of our beautiful planet Earth. And so earlier this week NASA delivered just that, courtesy of the high-definition EPIC camera (yes, that’s a real acronym) aboard the DSCOVR spacecraft positioned nearly a million miles away toward the Sun. The image above was captured on July 6, 2015, using the camera’s visible-light channels… it’s how Earth would appear to our eyes were we there (with the help of a telephoto lens, that is.)
And it really is a “blue marble” image, of the kind previously only captured by departing (or approaching) planetary exploration spacecraft or from inside Moon-bound Apollo capsules (see below)… you simply can’t get a shot like this from low-Earth orbit!
“This is the first true blue marble photo since 1972.”
– John Grunsfeld, NASA, July 24, 2015
A new image from New Horizons has emerged, showing a new, smaller mountain range on the southwestern border of Pluto’s “heart” region. The image was captured during the July 14 flyby, during which time the spacecraft passed less than 8,000 miles from the planet’s surface.
At 3 p.m. EDT today, July 15 2015, from the Johns Hopkins University’s Applied Physics Laboratory in Laurel, Maryland, the New Horizons team revealed to the world the first high-resolution image acquired of the surface of Pluto. This was obtained during the historic July 14 flyby with New Horizons’ “Ralph” camera, and it’s our very first close-up view of this distant world’s fascinating, beautiful, and surprisingly crater-free surface! Of course more will be coming as the days, weeks, and months pass, and many further studies will be done to determine the nature of all of the features revealed, but for now – enjoy.
This is truly an amazing time in space exploration!
It’s happened! At 7:49 a.m. EDT (11:49 UTC) this morning, July 14 2015, NASA’s New Horizons spacecraft performed its close pass of Pluto and, fourteen minutes later, its moon Charon. While we won’t receive a signal from New Horizons until about 9 p.m. tonight (and image data from the flyby won’t arrive until July 15th) NASA did share this gorgeous image this morning just before the flyby. it was taken by New Horizons on July 13th and has a resolution of about 4 km (2.4 miles) per pixel, and shows the distant world in approximate true-color. It’s highly-publicized “heart” feature is seen front-and-center – proof that Pluto loves ya!
And, according to New Horizons PI Dr. Alan Stern, this is but a teaser for the “data waterfall” that’s to begin arriving tomorrow! What an amazing day for science.
“The New Horizons team is proud to have accomplished the first exploration of the Pluto system. This mission has inspired people across the world with the excitement of exploration and what humankind can achieve.”
– Dr. Alan Stern, New Horizons PI, SwRI
The spacecraft is now moving away from the Pluto system at over 30,000 mph. It will spend the next 16 months transmitting data from the flyby back to Earth so scientists can fill in the long-missing gaps on our knowledge of Pluto and its family of moons.
Check back at the New Horizons site for updates.
“It’s truly amazing that humankind can go out and explore these worlds.”
– Alice Bowman, New Horizons Mission Operations Manager
Update: I had a chance to talk about Pluto with Nerdist.com writer Sarah Keartes – check out her article here.
Also, there was a funny segment by Stephen Colbert and Neil deGrasse Tyson (whom I do not completely agree with regarding Pluto) on the night of the flyby about these images of Pluto – check that out below!
This is Pluto, imaged by New Horizons’ LORRI camera on July 12. It’s (once again) the best view yet, captured from a distance of 2.5 million km / 1.5 million miles. Check out all that geology – craters, depressions, chaos terrain of some sort… at no time in human history has anyone ever seen this world in such detail.* And tomorrow, the spacecraft will pass within a scant 7,767 miles of its surface at 7:49 a.m. EDT / 11:49 UTC, its high-resolution Ralph camera firing away.
So… WHO’S EXCITED??
NASA and JHUAPL will be hosting media broadcasts tomorrow morning starting at 7:30 a.m. EDT during the flyby events (although “live” footage won’t be possible due to the fact that the spacecraft is four and a half hours of light-travel time away.) See the schedule here, and of course you can always tune in to watch NASA TV with the link in the header bar above.
*Although artist Don Dixon pretty much nailed Pluto’s appearance in some illustrations he made in 1979 – check those out here.
