Even after decades of observations and a visit by NASA's Voyager 2 spacecraft, Uranus held on to one critical secret -- the composition of its clouds. Now, one of the key components of the planet's clouds has finally been verified.

Any telescope that reaches the launch pad in the 2030s likely will look much different than the concepts four teams are currently studying to inform the 2020 Decadal Survey for Astrophysics, but the studies do offer a roadmap. Here’s a brief overview of each:

Many of NASA's most iconic spacecraft towered over the engineers who built them: think Voyagers 1 and 2, Cassini or Galileo -- all large machines that could measure up to a school bus. But in the past two decades, mini-satellites called CubeSats have made space accessible to a new generation. These briefcase-sized boxes are more focused in their abilities and have a fraction of the mass -- and cost -- of some past titans of space.

The German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) and the United States corporation Teledyne Brown Engineering (TBE) are announcing the completion of the development and manufacturing process of the DESIS hardware. Operating the DLR Earth Sensing Imaging Spectrometer (DESIS) on the International Space Station (ISS) makes DLR the first user of the revolutionary multiplatform system MUSES (Multi User System for Earth Sensing) that was installed on board the ISS in 2017. The launch of the DESIS joint venture is scheduled for summer 2018 from Cape Canaveral and will be lifted into space by a SpaceX Falcon 9 rocket.

Supermassive black holes, SMBHs, are thought to lurk at the hearts of many, if not all, large galaxies, including Earth’s Milky Way. But when galaxies merge, the smaller galaxy may leave its own SMBH in a wide orbit within the new host.

The Wide-field Infrared Survey Explorer (WISE) has been featured often in these pages, usually in terms of brown dwarfs and the possibility of uncovering a small star or brown dwarf closer than Proxima Centauri. But while we still have no evidence of such, we do have abundant data on brown dwarfs, as well as a useful compendium of objects that come close to the Earth. For WISE, launched in 2009 and placed into hibernation in 2011 upon completion of its primary mission, was reactivated in 2013 as NEOWISE. The goal is now the observation of asteroids and comets both near and far by way of characterizing their size and composition.

The wind on Mars is an artist, or at least it tries really hard to be one. It flutters up and down mountains, winding along valleys, dragging its wings in the sand and building up really amazing structures that could win any sand sculpture award.
