USA Will Launch Satellite Without Rocket: ALASA Concept by Darpa
Witout rocket but with powerful US F-15 jet Plane. Airborne Launch Assist Space Access, or DARPA ALASA, a current program of the US defense technology agency DARPA "designed to produce a rocket capable of launching a 100-pound satellite into low Earth orbit for less than $1 million." The program was conceived, then announced in 2011, and funded development work began in 2012. Credit video: Darpa Traditional launch methods of satellites are too costly to put small payloads into orbit without a larger payload accompanying it to make the launch worth the expense. Current launches of sub-100-pound satellites are performed as "piggyback payloads" on launches of much larger spacecraft, usually headed for geostationary orbit, and are released at the altitude of the primary payload. In addition, range costs of operating from ground-based infrastructure have escalated as they have aged, accounting for up to 35 percent of the launch cost. This restricts the number of light satellite launches to 10-12 per year, which could be increased if small payloads could be launched into space affordably and without ground range constraints. Air-launching satellites was first seriously considered during the 1950s and 1960s, but small payloads in the 100-pound class at the time did not have effective capabilities, so the method was overlooked. The first air-launched rocket to put a satellite into orbit was the Orbital Sciences Corporation Pegasus on 13 June 1990, but it was deployed from a heavily modified and expensive Lockheed L-1011 airliner. The ALASA program's objective is to use an unmodified aircraft platform (except for software) that does not have to be dedicated to the mission to place a 100 lb satellite into orbit that requires only 24 hours notice to integrate and launch the payload, with the ability to re-plan the launch in flight and relocate the aircraft to any civilian airport or military airfield in a crisis situation, while using onboard GPS/inertial position reporting rather than ground-based radar tracking. In the first phase, Boeing, Lockheed Martin and Virgin Galactic were funded to explore different Alasa system concepts while Northrop Grumman, Space Information Laboratories and Ventions were contracted to work on enabling technologies that could be used by any or all of the system teams. In December 2012, DARPA announced that the ALASA program would provide the launch vehicle Booster for another DARPA program that is intending to release a "constellation of 24 micro-satellites (~20 kilograms (44 lb) range) each with 1-meter imaging resolution." In May 2013, DARPA requested US$40 million for a second year of ALASA program funding in spring 2013.

Beginnings of Skynet: The Best Robots in the World Meets in DARPA Robotics Challenge Finals 2015
The winner of this final is the Kaist Korean Team, that won 2 millions dollars. DARPA Robotics Challenge (DRC) is a competition funded by DARPA (Defense Advanced Research Projects Agency). The competition takes place from 2012 to June 2015. The stated aim is to develop semi-autonomous ground robots that can perform "complex tasks in hazardous environments, degraded and built by man" 1. The DRC following the DARPA Grand Challenge and the principle of the DARPA Urban Challenge. The competition began in October 2012. Originally, it was to be held for about 33 months with three competitions including a Virtual Robotics Challenge (HRV), which took place in June 2013 and two challenges "real" tests in December 2013 and the final in June 2015. Besides stimulating the development of semi-autonomous robots, the DRC also seeks to make the robotics software and the development of robotic systems more accessible in the future. To this end, the DRC funded the adaptation of the robot simulator GAZEBO by the Open Source Robotics Foundation (OSRF), and construction by Boston Dynamics ATLAS six robots that are given to teams that have performed the best scores in the Virtual robotics challenge (HRV).

DARPA testing jetpack for soldiers
DARPA and Arizona State University are testing a jetpack for US troops, but it has at least one major drawback. The device will not allow soldiers to fly, instead increasing the ground speed of the wearer, allowing them to run a four minute mile.
