Here's a wonderful feature about my favorite constellation and the galaxy's most awesome telescope (at least one of them!) from NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California.
The HiRise imager in orbit around Mars shoots a continuous stream of data about its surface our way. Nasa's posted 44,000 images so far, each available in all sorts of formats and projections. You could have one a day as your desktop background and never run out.
This is cool as hell. “While thousands turned out to watch NASA’s Space Launch System (SLS) recently complete a full-scale test of its booster, few were aware of the other major test occurring simultaneously.” NASA’s High Dynamic Range Stereo X (HiDyRS-X) camera project captured the test like we've never seen before, and recorded propulsion video data in unprecedented detail.

The color changes have become common in the spring and early summer due to seasonal precipitation and climate patterns. Spring is the wettest season in northwestern Iran, with rainfall usually peaking in April. Snow on nearby mountains within the watershed also melts in the spring. The combination of rain and snowmelt sends a surge of fresh water into Lake Urmia in April and May. By July, the influx of fresh water has tapered off and lake levels begin to drop.
The fresh water in the spring drives salinity levels down, but the lake generally becomes saltier as summer heat and dryness take hold. That’s when the microorganisms show their colors, too. Careful sampling of the water would be required to determine which organisms transformed the lake in 2016, but scientists say there are likely two main groups of organisms involved: a family of algae called Dunaliella and an archaic family of bacteria known as Halobacteriaceae.
While Lake Urmia has shifted from green to red and back several times in recent years, trends suggest that a red Urmia could become increasingly common.
One million miles from Earth, hanging in space between Earth's gravitational pull and the sun's, is the DSCOVR satellite and NASA's incredible EPIC camera. Every two hours, EPIC takes a photo of Earth "to monitor ozone and aerosol levels in Earth’s atmosphere, cloud height, vegetation properties and the ultraviolet reflectivity of Earth." The above video combines one year of those images.
From the NASA Goddard Space Flight Center:
The primary objective of DSCOVR, a partnership between NASA, the National Oceanic and Atmospheric Administration (NOAA) and the U.S. Air Force, is to maintain the nation’s real-time solar wind monitoring capabilities, which are critical to the accuracy and lead time of space weather alerts and forecasts from NOAA.
Having successfully slipped into orbit around Jupiter, Juno sent its first image back to Earth.

NASA on Tuesday released an image taken by the satellite on Sunday from a distance of 2.7 million miles; it even shows the Great Red Spot, though the famous storm has been shrinking in recent decades and may not be as great as it once was.
“We’re quite pleased that we survived going through Jupiter orbit insertion,” said Candice Hansen-Koharcheck, a scientist at Planetary Science Institute in Tucson who is responsible for the operation of the camera. “The fact it’s a beautiful image is already a good thing.”

This picture provides a vivid illustration that Jupiter's atmosphere has more color contrast than any other atmosphere in the solar system, including Earth's. Data obtained from these and other New Horizons images taken during the encounter will provide valuable insight into the processes occurring on this gas giant.
Hey Jupiter, I hope you're ready for your close-up.
Recently, I was granted the rare privilege of stepping inside one of the largest cleanrooms at NASA's Jet Propulsion Laboratories. I was there to learn about this year's blockbuster space mission, Juno, and chat with some super smart science and engineering people who worked on the project.
