Impact (novel)

Impact is a science fiction thriller novel by American writer Douglas Preston, published on January 5, 2010 by Forge Books. The novel is the third book in the Wyman Ford series. The book was reviewed on All Things Considered in February 2010.

Plot summary

Ex-CIA agent Wyman Ford returns to Cambodia to investigate the source of radioactive gemstones and uncovers an unusual impact crater. A young woman on the other side of the world photographs a meteoroid's passage in the atmosphere with her telescope and deduces that it must have struck on one of the islands just offshore from Round Pond, Maine. A NASA scientist analyzing data from the Mars Mapping Orbiter (MMO) spots unusual spikes in gamma ray activity. These threads intersect with discovery of an alien device that has apparently been on Deimos, one of the two moons of Mars, for at least 100 million years. Something has caused it to activate and fire a strangelet at Earth, setting off the events in the novel.

Timeline

The events in this novel follow those of The Codex, Tyrannosaur Canyon, and Blasphemy. As such, Wyman Ford is the protagonist once again (having appeared in Tyrannosaur Canyon and Blasphemy), and the character of Stanton Lockwood III (who debuted in Blasphemy) also returns.

Free fall

In Newtonian physics, free fall is any motion of a body where gravity is the only force acting upon it. In the context of general relativity, where gravitation is reduced to a space-time curvature, a body in free fall has no force acting on it and moves along a geodesic. The present article only concerns itself with free fall in the Newtonian domain.

An object in the technical sense of free fall may not necessarily be falling down in the usual sense of the term. An object moving upwards would not normally be considered to be falling, but if it is subject to the force of gravity only, it is said to be in free fall. The moon is thus in free fall.

In a uniform gravitational field, in the absence of any other forces, gravitation acts on each part of the body equally and this is weightlessness, a condition that also occurs when the gravitational field is zero (such as when far away from any gravitating body). A body in free fall experiences "0 g".

The term "free fall" is often used more loosely than in the strict sense defined above. Thus, falling through an atmosphere without a deployed parachute, or lifting device, is also often referred to as free fall. The aerodynamic drag forces in such situations prevent them from producing full weightlessness, and thus a skydiver's "free fall" after reaching terminal velocity produces the sensation of the body's weight being supported on a cushion of air.

Charles "Nish" Bruce

Sergeant Charles Christian Cameron "Nish" Bruce QGM (8 August 1956 – 8 January 2002) was a former British Army soldier and freefall expert of high altitude military parachuting who served in 22 (SAS) Special Air Service (1982–88). He served with the 22 SAS in the Falklands War, on anti-drug operations in South and Central America and in Northern Ireland during Operation Banner for which he was awarded the Queen's Gallantry Medal in 1986.

He received the South Atlantic Medal in 1982 with B Squadron of the 22 Special Air Service and the General Service Medal with the 2nd Battalion, Parachute Regiment for services in Northern Ireland during The Troubles.

Family & Early Life

Bruce was born in Chipping Norton in 1956, middle son of Ewen Anthony Guy Cameron Bruce. He was the paternal grandson of Major Ewen Cameron Bruce (of Blaen-y-cwm).

Military career

Bruce joined the Parachute Regiment in 1973 at age 17 and in 1978 spent 4 years with The Red Devils Display Team participating in test jumping, international exhibitions and competitions before passing SAS selection and joining 22 SAS in April 1982.

Free fall (disambiguation)

Free fall is the ability to achieve the sensation of weightlessness (for example to be falling freely in an atmosphere, or to be in zero-g). In skydiving, the term freefall is also used for the portion of the skydive prior to the deployment of a parachute, even though significant portions of it are at terminal velocity rather than freely accelerating in gravity.
