If you heart Pluto, you’ll love the sharpest, closest close-up of the dwarf planet, just sent back by NASA’s New Horizons probe.
The images, captured from a distance of 10,000 miles during the July 14 flyby, include a heart-shaped block of nitrogen-rich ice right on the edge of the big heart-shaped region known informally as Tombaugh Regio.
You can also see the craggy blocks of water ice that form the al-Idrisi mountains, bull’s-eye impact craters on Sputnik Planum, and ripples and layers in Pluto’s icy crust. The pictures have a maximum resolution of 250 feet per pixel, which is less than the length of a football field.
“It’s really exciting to see SpaceX and Boeing with hardware in flow for their first crew rotation missions,” Kathy Lueders, manager of NASA’s Commercial Crew Program, said today in a news release. “It is important to have at least two healthy and robust capabilities from U.S. companies to deliver crew and critical scientific experiments from American soil to the space station throughout its lifespan.”
Even though the first order went to Boeing, it has not yet been determined whether Boeing’s CST-100 Starliner capsule or SpaceX’s Crew Dragon capsule will go first. The contracts required NASA to put in its orders early, but the scheduling decisions and required certifications will be made at a later time.

The bright heart of Pluto has been burned into our consciousness, thanks to scads of high-resolution pictures. But a new set of images from NASA’s New Horizons mission provides an all-around view of the dwarf planet, including the splotchy shapes that went out of view days before the time of closest approach on July 14.

The imagery was captured over the course of a full Plutonian day, which is 6.4 Earth days long. New Horizons’ Long Range Reconnaissance Imager and the Ralph / Multispectral Visible Imaging Camera were trained on the icy worlds as the distance to Pluto decreased from 5 million miles on July 7 to 400,000 miles on July 13.

NASA has released new artwork that reflects the latest look for its Orion deep-space crew vehicle – and it’s highly reflective.
Orion’s shiny back shell isn’t just for show: In Thursday’s update, NASA explains that the silvery, metallic-based thermal control coating is designed to reduce heat loss when the spacecraft is pointed toward the dark chill of outer space, and limit high temperatures when it’s exposed to the sun.
“You’re trying to hit this sweet spot because when you’re looking at the sun, you don’t want to get too hot, and then when you’re not looking at the sun and instead in darkness, you don’t want to lose all the heat that the spacecraft generates,” John Kowal, NASA’s thermal protection system lead for Orion, explained in the update.

JOINT BASE LEWIS-McCHORD, Wash. – I’ve looked at clouds from both sides now – from below, on the receiving end of an all-day rain; and from above, where NASA’s flying laboratory is dissecting those rain clouds.
For more than six hours on a rainy Saturday, I rode along as a DC-8 jet bristling with electronic gear took radar and microwave measurements of the clouds hanging over the Olympic Peninsula. The flight is part of a months-long campaign called the Olympic Mountain Experiment, or OLYMPEX, which is being conducted by NASA and the University of Washington.
OLYMPEX is aimed at fine-tuning the algorithms that scientists use to translate the data coming from on-the-ground weather installations and satellites like the recently launched Global Precipitation Measurement Mission Core Observatory into weather and climate projections.
In the process, they’re addressing a scientific problem we’ve known about since Judy Collins first sang about clouds in the ’60s: We really don’t know clouds at all.

JOINT BASE LEWIS-McCHORD, Wash. — The weather forecast for the Olympic Peninsula is dark and rainy, and that’s putting the scientists behind NASA’s OLYMPEX campaign in a sunny mood.
“The really exciting thing that everyone’s talking about is, there’s this huge rain event that’s coming in,” says Rachael Kroodsma, an atmospheric scientist from NASA’s Goddard Space Flight Center, helping to get a specially outfitted DC-8 plane ready to fly into the storm this week. “There’s a lot of buzz about that. … It’s a good start to the campaign.”
Usually, bad weather is bad news.
Not for OLYMPEX, the Olympic Mountain Experiment.
Under the leadership of NASA and the University of Washington, the months-long effort is using aerial observations as well as a bevy of radars and rain gauges to validate orbital data from the Global Precipitation Measurement satellite, also known as GPM. The $3 million campaign is the latest of several field studies aimed at making sure the satellite readings reflect ground truth.

Scientists with NASA’s New Horizons mission say that at least a couple of the miles-high mountains on Pluto look as if they’re ice-belching volcanoes, providing further evidence that the dwarf planet is geologically active.
Although the case for cryovolcanoes isn’t yet rock-solid, it’s the “least weird explanation” for the observations of 2-mile-high Wright Mons and 3-5-mile-high Piccard Mons, said Oliver White of NASA’s Ames Research Center, a member of the mission’s geology team.
If the mountains’ status is confirmed, “that would be one of the most phenomenal discoveries of New Horizons,” White told reporters. “Whatever they are, they’re definitely weird.”

Pluto’s potential status as a volcanic world was just one of the revelations that came to light on Monday during a review of New Horizons’ latest discoveries at the annual meeting of the American Astronomical Society’s Division for Planetary Sciences in National Harbor, Md.
“The New Horizons mission has taken what we thought we knew about Pluto and turned it upside down,” Jim Green, director of planetary science at NASA Headquarters, said in a news release about the findings.

Boeing says it’s out of the running for NASA’s next contract to deliver cargo to the International Space Station, but it’ll still be sending up cargo as well as astronauts on its CST-100 Starliner spaceship under the terms of different deal.
The update came as NASA said that its selection of contractors for the second round of commercial resupply services for the space station, previously scheduled to be announced today, would have to wait.
“CRS2 is a complex procurement,” NASA said in an emailed statement. “The anticipated award date has been revised to no later than January 30, 2016, to allow time to complete a thorough proposal evaluation and selection. Since the agency is in the process of evaluating proposals, we are in a procurement communications blackout. For that reason, NASA cannot answer questions about this procurement at this time.”
The CRS2 contracts are likely to be worth billions of dollars, and would cover a period running from 2018 to 2024.

Scientists studying Mars’ atmosphere say solar storms probably played a big role in transforming the Red Planet from the warm, hospitable place it was billions of years ago to the cold world it is today.
The mission’s name is an acronym that stands for Mars Atmosphere and VolatileEvolutioN. Its aim is to measure the current dynamics of the Martian atmosphere – and then factor those measurements into models to figure out how Mars lost much of its air billions of years ago.

NASA is opening its doors to recruit a fresh batch of astronauts – and by the time the candidates finish training, they just might be able to ride shiny new space taxis into orbit.
That’s close to the time when Boeing’s CST-100 Starliner and SpaceX’s Dragon V2 are expected to start ferrying astronauts to and from the International Space Station, representing the first crewed spaceships to be launched into orbit from U.S. soil since the shuttle fleet retired in 2011.
