Planetary defence game


















Only problem i have is the font on the instructions seem like something from a commodore 64 Its a keeper for me. Seems like a decent and new take on the classic Missle Command. I like it as much as I like Missle Command. It's worth "it" to me, especially free. All of the complaints were a waste of time to read. This game installs easily, but you do have to hunt for the shortcut Icon inside the program file. The ease of installation is the only good thing you can say about this game.

I wish I could get back the three minutes it took to evaluate. There are absolutely no advantages to this game when comparing it to hundreds of other things you can do to waste your time. Works perfectly on Vista Home Premium, quite nice but not a keeper! Hey guys, where's my review?

I posted it over three hours ago and cecked that i had been received by trying to post it a second time where you get the message about having already posted that comment.

I will keep it though just to kill time every once in a while. Thanks anyways. This game installed easily, and actually works quite well on the older machine.

Many games don't work well on slower machines due to slower graphics processors. This is pretty much a circular version of the old "Missile Command" from the older arcade days, but with some updates.

Not bad at all. I'll enjoy it. I like games where I can blow stuff up. I think it should be a nice game. I don't know why don't like it, probably I am too young or too old for this type of games, I don't have patience for this type of slow moving missiles. If the game is in as nine bucks how is it that there could be any more than 1 or 3 people display on the character and the exact location when in the cockpit.

I am amazed at this action and wish it was changed so off to bed thanks goatotd. Thanks a lot. Just love these shoot 'm up games. Cant get enough. Big time, you guys still are working that hard for all of us Oh yeak You will find a shortcut in the start menu programs list, where you can right click on send to - shortcut to the desktop. It is fun for about 30 seconds I forgot to add some examples, lol. All rights reserved.

Lode Doomer. What are the different types of meteorites? What do most meteorites look like? Most meteorites found on Earth are pebble to fist size, but some are larger than a building.

Meteorites may look very much like Earth rocks, but some have the appearance of a burned exterior called a fusion crust. They may also have thumbprint-like depressions. This crust forms when the exterior of the meteoroid is melted by friction as it passes through the atmosphere. Scientists classify meteorites into three groups: stony meteorites, iron meteorites, and stony iron meteorites.

These have high amounts of iron and nickel. Scientists thought they knew the origins of the stony and stony iron meteorites, but new evidence has caused them to reconsider.

Stony-iron meteorites are in between the other two types of meteorites. Meteor showers occur when Earth passes through the trail of dust left by a comet along its highly elliptical orbit. The particles enter Earth's atmosphere and most burn up. Some meteor showers, such as the Perseids in August and the Geminids in December, occur annually when Earth's orbit takes it through the debris path left along the comet's orbit.

Comet Halley's trails are responsible for the Orionids meteor shower. What is an asteroid? Which is not an asteroid? Asteroid features. Asteroids are rocky bodies ranging from miles km wide down to dozens of meters, which orbit our Sun or another asteroid. Ceres is the largest of the asteroids, and Vesta is the second largest. Most asteroids are irregularly shaped and all have craters from impacts with other asteroids.

However, the largest asteroid, Ceres, has sufficient gravity to become nearly spherical, so it is also classified as a dwarf planet! Vesta, another large asteroid, has evidence of ancient lava flows on its surface. Some asteroids, such as Ceres, have large amounts of ice.

Asteroids are too small to have an atmosphere, so they cannot have storms. What are the types of asteroids? Asteroids are classified by their composition. These asteroids are composed of silicate rocks along with some organic compounds and hydrated minerals like clays.

Stony or silicate-rich S-type asteroids dominate the inner part of the asteroid belt, closest to the Sun. These asteroids are composed of rocky materials and small amounts of metallic iron.

M-type metallic asteroids are predominantly metallic iron and nickel. Where do most meteorites come from? Meteorites are ejected from a rocky body by an impact by an asteroid or comet. More than 50, meteorites have been found on Earth. Most come from asteroids; in particular, several different types of meteorites appear to be from the asteroid Vesta. A few meteorites originate from the Moon and Mars. Meteorites also fall on other solar system bodies.

What makes an impact crater? Craters are roughly circular, excavated holes made by impact events. When an asteroid or comet strikes the solid surface of a planet or another asteroid, a shock wave spreads out from the impact, creating a crater much bigger than the asteroid or comet. The asteroid or comet is shattered into small pieces and may melt or vaporize.

How long have asteroids been hitting the planets? Do large or small asteroids hit the Earth more frequently? Early in the formation of the solar system 4. Impacts still occur across our solar system, but at a reduced rate. Scientists estimate that Earth and the other terrestrial planets are struck by, on average, five asteroids less than 2 kilometers a little over 1 mile across every million years.

Larger impacts also still occur, but are more rare. Which is hit by the smallest particles from asteroids and comets? The Moon does not have an atmosphere to shield the surface from small particles; Earth, Venus, and Mars have atmospheres that burn up the smallest particles from asteroids and comets.
