60 years ago today, a small satellite ushered in the U.S. space program in a big way.
The U.S. is celebrating a milestone — 60 years in space today — with the anniversary of the launch of Explorer 1.
The small 6 foot, 9 inch, 31-pound satellite lifted off from launch complex 26A on Cape Canaveral at 10:48 p.m. Eastern Time (3:48 UT on February 1st). Explorer 1 used a four-stage Juno I rocket, a modified Army Jupiter-C rocket with an extra stage on top to reach orbit.

The Soviet Union had stunned the world just a few months prior with the launch of Sputnik 1 on October 4, 1957, closely followed by Sputnik 2 a month later. The launch of Explorer 1 finally put the United States in the space race.
The success of Explorer 1 followed a string of dramatic failures at the Cape in late 1957, including the explosion of the U.S. Naval Research Laboratory's Vanguard TV3 just seconds after liftoff on December 6, 1957. (The beleaguered Vanguard program finally got off the pad on March 17, 1958, and Vanguards 1, 2 and 3 are actually still in orbit around Earth today.) Explorer 1 reentered on March 31, 1970, after more than 58,000 orbits around Earth.
The launch required new innovations, among them the development of a fuel powerful enough to carry the rocket into orbit. Scientist Mary Sherman Morgan played a key role in the development of the Hydyne fuel used in the first stage of the Juno I rocket, George D. Morgan recounts in Rocket Girl.
Explorer 1 was the first mission to carry a scientific payload: a modified Geiger counter to detect cosmic rays, two micrometeorite detectors, and five temperature sensors. Legend has it that JPL engineer George Ludwig actually drove across the country to deliver the payload package to the Cape, stowed in the trunk of his 1956 Mercury sedan. Thanks to its cosmic-ray counter, Explorer 1 detected the Van Allen radiation belts surrounding Earth. The belts, named after James Van Allen (University of Iowa), who led the team that designed the instrument, were the first scientific discovery made in space.
Van Allen, Wernher von Braun, and William Pickering held a press conference in Washington D.C. shortly after the successful launch of Explorer 1, hoisting a model of the satellite over their heads in a now iconic image. Van Allen later became a key advocate for a civilian-led rather than a military-controlled space agency, Abigail Foerstner writes in her biography, The First Eight Billion Miles.
Amateur astronomers across the U.S. had been formally enlisted to keep an eye on satellites as part of Operation Moonwatch, a project that complemented professional tracking stations. Seasoned from the hunt for Sputnik 1, volunteers were at the ready to monitor Explorer 1 and the Vanguards. However, as W. Patrick McCray recounts in Keep Watching the Skies! The Story of Operation Moonwatch, the satellites were actually pretty faint and hard to find. 'Hells Bells,' one amateur exclaimed, 'couldn't they put a larger one up there?' By February 10th, some 200 teams worldwide had nabbed only 11 confirmed sightings of Explorer 1.
The U.S. space program grew quickly from those humble beginnings. NASA wasn't even 'NASA' yet when Explorer 1 launched: the National Advisory Committee for Aeronautics (NACA) wouldn't become the National Aeronautics and Space Administration until designated as such by President Eisenhower later that year on October 1, 1958. But just over a decade later, humans would walk on the Moon. Minitube for youtube 3 1.
What will the next 60 years in space bring? In 2018, watch for launches of the Parker Solar Probe billed as the first spacecraft to 'touch' the Sun, the next-generation exoplanet-hunting Transiting Exoplanet Survey Satellite (TESS), the Mars Insight geodesy mission, and much more — all continuing the legacy that started 60 years ago with Explorer 1.

Task Explorer is an advanced Task Manager tool with emphasis on, not just monitoring what applications are running, but on finding out what applications are doing. The UI focuses on expedience and getting real time data of what the processes are doing at any given moment. Relevant data are provided in easy to access (as less clicks as possible) panels, with no need to open windows or windows of sub windows, instead additional information's for selected entries are shown in the lower half of the panel. Allowing to browse the detailed information's using arrow keys. And most data are refreshed continuously, as seeing the dynamic of values often grants additional insight.
On Windows TaskExplorer is powered by the ProcessHacker library.
TaskExplorer features:
- The Thread Panel contains a stack trace for the selected thread giving even more insight in wat the selected application is doing right now. This is also very useful to debug deadlocks or performance issues.
- The processes memory can be viewed and edited from the Memory Panel, which provides an advanced memory editor and string search capability.
- In the Handles Panel all open handles are shown, with useful information's like file name the current file position and size, these allow to see what a program is actually working on right now disk wise.
- The Socket Panel shows all open connections/sockets per process providing also data rate information, in the settings one can enable the display of pseudo UDP connections created from ETW data. That is every destination endpoint for UDP packets will be shown as an own entry in the sockets panel allowing to monitor with whom a program is communicating.
- The Modules Panel shows all loaded dll's and memory mapped files, allowing to unload them as well as to inject a dll. And many more panels like Token, Environment, Windows, GDI, .NET, etc…. By double clicking on a process, the Task Info panels can be opened in a separate window enabling the viewing of properties of multiple processes simultaneously.
- The system monitor aspect of the application is also well developed. The toolbar provides decently sized graphs providing not just CPU usage but also usage of Objects, handles, network and IO/disk access.
- The system info panels show All Open Files in the system, All Open Sockets by programs, and the services Panel allows viewing and controlling all system services including drives.
- The performance panels for CPU, Memory, Disk I/O, Network and GPU provide large graphs showing the usage of system resources in a detailed manner. The System info panel can be collapsed completely providing more space for the Task info panels. So Instead being a panel of the main window, or additionally, the system info panels can be opened in an own window using the appropriate toolbar button.
