Q: What are the advantages of a low Earth orbit satellite?
A: In a low Earth orbit satellite, the escape velocity is in the region of 25 km/s. That is slower than the escape velocity of an automobile, but faster than an airliner. You have more control over your spacecraft, as you are flying a fixed trajectory. You are also the highest quality satellite you can get. If you get the top quality spacecraft, with micro-satellites instead of humans, you can reduce the amount of trouble that you get in space.
Also you can get the satellite in the right spot at the right time. Space in the 1980's was very congested. Even with the small rockets, the launchers were using both jet and rocket engines, so you couldn't use both at the same time. A small satellite, one-two meters we've done it a couple of times, and for us, the end result is fantastic, when we start the data acquisition at 28 days," said Nick Lance, another team member.
Seconds after the launch, the first image from the instrument showed a bright corona in the northern hemisphere. A few minutes later, a second image showed a caldera in the equatorial region, and then two more images that showed the same hot feature associated with the corona. The instrument subsequently deployed a 40-micrometer (1-micron) radio antenna and placed it on the Earth-facing side of the mount. At the time the 1-meter antenna was installed, a radio meteorological station positioned just before the crater was in the early stages of its regular observations. The timing was just as it would be for a meteor impact, but instead of the radio meteorology station showing the meteor, the meteor would be picked up by the high-powered radar screen in the crater. Although the radar service downplayed the exposure of the station, this program should have shown meteor impacts, such as those of the 1920's.
