NASA Announces Retirement of TRACE Satellite
NASA’s Transition Region And Coronal Explorer (TRACE) satellite, launched back on 1 April 1998 was officially retired by NASA as of this past Tuesday. TRACE has been allowing scientists to study the Sun, especially its corona. The work of TRACE will now be “carried out by NASA’s newest eye on the sun, the Solar Dynamics Observatory (SDO), a Goddard-built spacecraft managed by the Science Mission Directorate’s Heliophysics Division.” Learn more about the changing of the guard in solar studies online now here.
Solar Dynamics Observatory Launched
Today at 10:23 AM EST, NASA successfully launched its Solar Dynamics Observatory (SDO). As NASA puts it, “SDO is designed to help us understand the Sun’s influence on Earth and Near-Earth space by studying the solar atmosphere on small scales of space and time and in many wavelengths simultaneously.” Learn more about the mission and watch a video of the launch online here.
Solar Dynamics Observatory Now Set for Tomorrow Morning
The Solar Dynamics Observatory (SDO) was due to launch today, but was postponed until at earliest tomorrow at 10:30 AM (EST). The purpose of SDO as stated by Dr. Tony Phillips of NASA is “to probe solar variability unlike any other mission in NASA history.” Furthermore, “it will observe the Sun faster, deeper, and in greater detail than previous observatories, breaking barriers of time-scale and clarity that have long blocked progress in solar physics.” To learn more about SDO, read Dr. Phillips article online here. To monitor its launch tomorrow, check out the SDO website here.
Astrocast.TV Episode 2
- A new NASA spacecraft called the Solar Dynamics Observatory (SDO) will
deliver startling images of the sun with ten times more detail than HDTV. The
goal of the mission is to help scientists zoom in on solar activity such as
sunspots, solar flares and coronal mass ejections, thus improving forcasts of
solar storms.
- “NASA’s Cassini mission to Saturn
and its’ fabulous moons continues to make incredible discoveries. In our next
episode we will explore Saturn’s largest moon – Titan – with huge hydrocarbon
resources and a possible ocean beneath the surface, as well as the gushing
geyers of Enceladus.”
