1. The Original Science Robot
Sixty years ago this week, the United States sent its first satellite into space on Jan. 31, 1958. The spacecraft, small enough to be held triumphantly overhead, orbited Earth from as far as 1,594 miles (2,565 km) above and made the first scientific discovery in space. It was called, appropriately, Explorer 1.

2. Why It's Important
The world had changed three months before Explorer 1's launch, when the Soviet Union lofted Sputnik into orbit on Oct. 4, 1957. That satellite was followed a month later by a second Sputnik spacecraft. All of the missions were inspired when an international council of scientists called for satellites to be placed in Earth orbit in the pursuit of science. The Space Age was on.
- Explorer 1 became the first successfully launched satellite by the United States when it was sent to space on January 31, 1958. A quick response to the Soviet Union's launch of Sputnik 1, Explorer 1's success marked the beginning of the U.S.
- Internet Explorer is Microsoft's venture into the Web Browser market. The initial version of Explorer was incarnated from Spyglass Mosaic which Microsoft licensed for a modest quarterly fee and a share of the non-Windows product revenues. As Microsoft decided to distribute Internet Explorer 'free of charge' with their Windows operating system, they were able to avoid most royalties.

3. It … Wasn't Easy
When Explorer 1 launched, NASA didn't yet exist. It was a project of the U.S. Army and was built by Caltech's Jet Propulsion Laboratory in Pasadena, California. After the Sputnik launch, the Army, Navy and Air Force were tasked by President Eisenhower with getting a satellite into orbit within 90 days. The Navy's Vanguard Rocket, the first choice, exploded on the launch pad Dec. 6, 1957.

4. The People Behind Explorer 1
University of Iowa physicist James Van Allen, whose proposal was chosen for the Vanguard satellite, had made sure his scientific instrument – a cosmic ray detector – would fit either launch vehicle. Wernher von Braun, working with the Army Ballistic Missile Agency in Alabama, directed the design of the Redstone Jupiter-C launch rocket, while JPL Director William Pickering oversaw the design of Explorer 1 and other upper stages of the rocket. JPL was also responsible for sending and receiving communications from the spacecraft.
5. All About the Science
Explorer 1's science payload took up 37.25 inches (95 cm) of the satellite's total 80.75 inches (2.05 meters). The main instruments were a cosmic-ray detector; internal, external and nose-cone temperature sensors; a micrometeorite impact microphone; a ring of micrometeorite erosion gauges; and two transmitters. There were two antennas in the body of the satellite and its four flexible whips formed a turnstile antenna that extended with the rotation of the satellite. Electrical power was provided by batteries that made up 40 percent of the total payload weight.
6. At the Center of a Space Doughnut
The first scientific discovery in space came from Explorer 1. Earth is surrounded by radiation belts of electrons and charged particles, some of them moving at nearly the speed of light, about 186,000 miles (299,000 km) per second. The two belts are shaped like giant doughnuts with Earth at the center. Data from Explorer 1 and Explorer 3 (launched March 26, 1958) led to the discovery of the inner radiation belt, while Pioneer 3 (Dec. 6, 1958) and Explorer IV (July 26, 1958) provided additional data, leading to the discovery of the outer radiation belt. The radiation belts can be hazardous for spacecraft, but they also protect the planet from harmful particles and energy from the Sun.

Today, these belts are known as the Van Allen Belts; two NASA spacecraft, the Van Allen Probes, have been exploring this region since 2012.
7. 58,376 Orbits
Explorer 1's last transmission was received May 21, 1958. The spacecraft re-entered Earth's atmosphere and burned up on March 31, 1970, after 58,376 orbits. From 1958 on, more than 100 spacecraft would fall under the Explorer designation.

10. What's Next?
All NASA missions can trace a lineage to Explorer 1. This year alone, we're going to expand the study of our home planet from space with the launch of two new satellite missions (GRACE-FO and ICESat-2); we're going back to Mars with InSight; and the Transiting Exoplanet Survey Satellite (TESS) will search for planets outside our solar system by monitoring 200,000 bright, nearby stars. Meanwhile, the Parker Solar Probe will build on the work of James Van Allen when it flies closer to the Sun than any mission before.
EXE Explorer is an interesting tool which can tell you everything you could ever need to know about the structure of a Windows executable file. (PE32, PE32+ (64-bit), NE, VxD and .NET executables are supported.)
Just open your target file and EXE Explorer provides quick access to all its internal structures. The full list: DOS, File, Optional and CLR headers, CLR Metadata streams, Sections, Directories, Imports, Exports, Resources, ASCII and Unicode Strings, .NET Metadata, Load Config, Debug, Thread Local Storage, Exceptions, Units, Forms, Packages, Classes, Flags and Version Info, with a hexadecimal view of file content as well.
If that seems technical, then it is: the program is aimed squarely at developers and other expert Windows users. But despite this there are a few elements which can be occasionally useful for every level of PC user.
If you're trying to figure out what a particular executable file is, or does, for example, then open it in EXE Explorer, click the Strings tab, and you'll see all the text strings it contains. These can include user prompts, URLs, file names, Registry keys, all kinds of interesting data which may tell you a lot more about the program itself. On1 photo 10 10 5 0 download free.
Or, if you'd like to extract an icon or image embedded within the executable, then open it with EXE Explorer, click the Resources tab, and browse to the item you need. Choose an icon, say, right-click it and select Save Resource, and EXE Explorer will extract it for you to an external ICO file.
What's New: WOW64 bug fixed
Verdict:
EXE Explorer has its limitations; viewing some resources seems a little difficult than it needs to be, for instance. The program is free, portable, and barely 1MB in size, though, so we probably shouldn't expect too much, and if you ever need to know more about EXE structures then it's definitely worth a try.
