Do you know about NASA - CHIPS Mission. I bet you dont...

CHIPS (Cosmic Hot Interstellar Plasma Spectrometer) is an American (NASA) astrophysics spacecraft that was launched by a Delta 2 rocket from Vandenberg AFB at 00:45 UT on 13 January 2003. The 60 kg, triaxially-stabilized spacecraft has a spectrograph covering the 9-26 nm wavelength band at a resolution of 0.1 nm, scanning the entire sky in chunks of 5 degree x 27 degree segments during each orbit. The targets are the hot and diffuse nebulae at about a million degrees temperature. The band covers several strong emission lines. Launch Date:   2003-01 13     Launch Vehicle:  Delta II Launch Site:   Vandenberg AFB, United States Mass:   60 kg  CHIPS carried out an all-sky survey of the diffuse background at wavelengths from  90  to 260 Å at a spectral resolution between about λ / 150 and λ / 40, and a spatial resolution of 5 to 15 degrees. CHIPS detected diffuse emission near 170 Å, but this turned out to be associated with the earth’s thin outer atmosphere or its int

Snow Storms occur on Martian Surface. May prove fatal for future missions.

 There are various types of storms on Mars. The most famous are dust storms, made of mineral particles lifted from the ground. We report a different type of storm, made of water ice particles. Other studies have pointed to the existence of CO2 ice snow storms in the deep polar night of Mars, but no water ice storm has ever been suggested to exist on Mars until now.
 Most of the time, Martian cloud particles evaporate before they reach the surface, like virgas on Earth. Water-ice cloud particles form during the cold Martian night. Because they are able to cool the surrounding atmosphere—by losing heat through the emission of infrared radiation—they can lead to cold air over warmer air within the cloud. This unstable condition triggers a descending plume of snow. These turbulent storms, which can only form at night, act to vigorously mix the atmosphere, and in some places, deposit snow on the Martian surface.
We propose that Martian snowstorms are analogous to small localized storms on Earth called microbursts, in which cold dense air carrying snow or rain is rapidly transported downwards from a cloud.
Through a combination of numerical simulations performed with a Mars weather model, which are supported by temperature profile observations from previous missions. There has been no direct observation of a water ice snow storm, which I’m sorry to say means no pictures! But the predictions performed by the model show their existence, and this is corroborated by temperature measurements.
Also, some clouds close to the surface of the Martian north pole by the Phoenix mission, and while their discoverers initially suggested a different type of cloud formation, our article shows that they could also be explained by a local snow storm.
The associated winds found in the storm are rather vigorous. Since they occur in the lower part of the atmosphere, one might want to avoid these turbulent events to ensure a safe landing.
These data were reported by scientist Franck Montmessin in an interview with RG.
