Propelled by its three “cores,” the Falcon Heavy is expected to make its maiden voyage in fall 2016. This behemoth will cement its credentials as the most powerful rocket in current operational status, overtaking the Delta IV Heavy. Image Credit: SpaceX The planned Feb. 5 launch of a United Launch Alliance (ULA) Atlas-V carrying […] NASA’s IBEX spacecraft has detected the four-leaf-clover-shaped pattern of our Solar System’s “tail.” Image Credit: NASA Three years of observations by NASA’s Interstellar Boundary Explorer (IBEX) have shown that the Solar System has a tail shaped like a four-leaf clover. The stream of particles that blows away from the Sun, known as […]
The Lockheed L-1011 aircraft departs Runway 12/30 at Vandenberg Air Force Base, Calif., at 6:27 p.m. PDT (9:27 p.m. EDT) on 27 June 2013. Almost an hour later, after reaching its required deployment position, Pegasus-XL was air-launched to begin its mission of deploying NASA’s IRIS solar observatory. Photo Credit: Robert C. Fisher / […] The planned launch of an Orbital Pegasus XL rocket has been delayed a day due to range power issues. Photo Credit: Randy Beaudoin, VAFB / NASA The launch of an Orbital Sciences Corporation Pegasus XL rocket with NASA’s Interface Region Imaging Spectrograph (IRIS) will have to wait a little longer. The launch is now […] Deployed from beneath the L-1011 aircraft, Pegasus-XL utilizes three solid-fuelled stages to deliver payloads weighing up to 980 pounds into low-Earth orbit. Wednesday’s flight will be the 42nd Pegasus mission since April 1990. Photo Credit: NASA / Orbital Sciences Corp. Orbital Sciences Corp. is ready to boost its 42nd Pegasus air-launched rocket aloft on […] Investigators believe that the TESS mission, which earlier failed to be accepted for further study in 2009, has a 98-percent probability of finding potentially-habitable transiting exoplanets, orbiting red dwarfs within 50 parsecs of Earth. Image Credit: European Southern Observatory NASA’s Astrophysics Explorer Program has selected two missions to be launched in 2017. The Transiting […] |
