Life cycle design

Life cycle design, also called environmentally conscious design or ecodesign, is an engineering method that minimizes a product's environmental impact across its entire life cycle.

Life in the Atacama

Life in the Atacama was a NASA-funded project, running from 2003 to 2005, in which autonomous rovers searched for microbial life in Chile's Atacama Desert as a test bed for future life-detection missions to Mars.

Life-cycle assessment

Life-cycle assessment (LCA), also called life cycle analysis or cradle-to-grave analysis, is a method for evaluating a product's environmental impacts from raw material extraction through disposal.

Life-cycle cost analysis

Life-cycle cost analysis (LCCA) is an economic method that totals an asset's acquisition, operating, maintenance, and disposal costs over its life, discounted to present value for comparing alternatives.

Life-support system

A life-support system, also called an Environmental Control and Life Support System, keeps humans alive where the environment cannot, providing oxygen, removing carbon dioxide, and managing water, waste, pressure, and temperature.

Life360

Life360 is a freemium family location-sharing and safety app launched in 2008 by Chris Hulls and run from the San Francisco Bay Area, with about 95.8 million monthly users.

Lifeboat (shipboard)

A shipboard lifeboat is a rigid survival craft carried on a ship's deck to evacuate crew and passengers in an emergency, regulated under the SOLAS convention.

Lift (data mining)

Lift, first described under the name "interest", is a data mining measure for association rules that compares observed co-occurrence of items with what statistical independence would predict.

Lift-off process

The lift-off process is an additive microfabrication technique that patterns evaporated metal films by dissolving a sacrificial resist stencil, used for contacts and interconnects in semiconductor and MEMS manufacturing.

Liftback

A liftback is a car body style with a single top-hinged rear door incorporating the rear window, combining fastback-like proportions with hatchback cargo access; Toyota coined the term in 1973.

Lifting body

A lifting body is a wingless aircraft or spacecraft that generates lift from its fuselage shape, allowing a returning space vehicle to maneuver and land on a runway.
