With its NROL-67 mission currently grounded at Cape Canaveral Air Force Station, due to ongoing problems in the aftermath of a radar tracking system fire, United Launch Alliance (ULA) is continuing its preparations for another Atlas V mission from the West Coast. The company will launch the 19th Defense Meteorological Satellite Program (DMSP) spacecraft, atop an Atlas V 401 vehicle, from Space Launch Complex (SLC)-3E at Vandenberg Air Force Base, Calif., within a 10-minute “window” which opens at 7:46 a.m. PDT Thursday, 3 April. When operational in a Sun-synchronous, near-polar orbit of about 450 nautical miles (830 km), the so-called “DMSP Block 5D3 Flight 19″ will join a network of satellites whose heritage extends back over five decades to provide strategic and tactical weather prediction in order to aid the U.S. military in planning operations at sea, on land, and in the air.

CAPE CANAVERAL AIR FORCE STATION, FL — Piece by piece, fabrication of all the major hardware elements for NASA’s inaugural unmanned Orion test flight, dubbed EFT-1, are coming together at Cape Canaveral and the Kennedy Space Center.
Orion is a state-of-the-art spacecraft and NASA’s next step in manned deep space exploration aimed at sending American astronauts back to the Moon and then beyond on voyages to Asteroids and Mars over the coming decades, if funding continues.

NASA released Thursday an image of a comet that, on Oct. 19, will pass within 84,000 miles of Mars — less than half the distance between Earth and our moon.

NASA achieved a major milestone this month in its effort to transform the agency’s Kennedy Space Center in Florida into a multi-user spaceport by successfully completing the initial design and technology development phase for the Ground Systems Development and Operations (GSDO) Program.

One of the biggest aviation events in the world kicks off this week in central Florida, headlined by air show demonstrations by performers such as Rob Holland, the GEICO Skytypers, the USAF F-22 Raptor demo team, and the U.S. Navy Blue Angels. Photos Credit: AmericaSpace / Mike Killian
Central Florida is known for space, whether it’s launching rockets with spacecraft on missions to enhance national security, support operations on the International Space Station, or explore worlds such as Mars. This week, however, the attention turns to one of the biggest, and most popular, aviation events in the world, one which promises to wow onlookers old and young alike. The 40th annual Sun N’ Fun International Fly-In and Expo, which takes place in Lakeland, Fla. (between Orlando and Tampa), will host a variety of air show performers and aviation-enthusiasts from across the country and will be headlined next weekend with the return of the U.S. Navy Blue Angels in their first Florida air show appearance since federal budget cuts (sequestration) grounded the team in 2013.

The closest the shuttle ever came to a launch at the time of abort was T-1.9 seconds, on 18 August 1994. So close was the shuttle to launch, the on-board General Purpose Computers had already moded to their 102 ascent software configuration at the time of the abort. Photo Credit: NASA
In the pre-dawn gloom of 18 August 1994, Space Shuttle Endeavour sat on her seaside launch pad at the Kennedy Space Center, Fla., bathed in million-candlepower xenon floodlights, as the final seconds of the countdown to her voyage into orbit evaporated. Although STS-68 would be her seventh flight, it was in many ways a repeat of her sixth, for the orbiter carried the massive Space Radar Laboratory for observations of the Home Planet. Barely four months earlier, on STS-59, Endeavour had flown SRL-1, and on STS-68 she would monitor changes between late spring and late summer. For astronaut Tom Jones, who flew both, the second flight offered him the chance to seize a new record for the shortest span—just 120 days—between a pair of missions. Alas, for Jones, today would bring him cruel fortune … and for his crewmate, Dan Bursch, it would be crueler still.

This mosaic shows Opportunity’s view while looking back to vast Endeavour crater from atop Murray Ridge by summit of Solander Point. Opportunity captured this photomosaic view on Feb. 16, 2014, (Sol 3579) from the western rim of Endeavour Crater, where she is investigating outcrops of potential clay minerals formed in liquid water.

A series of Martian wind events over the past few months has given NASA’s long-lived Opportunity rover a big power boost during its current explorations atop a Red Planet mountain that’s a scientific goldmine.
Altogether, Opportunity has received about a 70-percent boost in power since early January, due to a combination of multiple wind-cleaning events and the advent of spring and more daily hours of sunshine in Mars’ southern hemisphere.

The discovery images of 2012 VP113. Three images of the night sky, each taken about two hours apart, were combined into one. The first image was artificially colored red, the second green, and the third blue. 2012 VP113 moved between each image as seen by the red, green, and blue dots. The background stars and galaxies did not move and thus their red, green, and blue images combine to show up as white sources. Image Credit/Caption: Scott Sheppard/Carnegie Institution for Science
A team of astronomers has announced the discovery of a new dwarf planet candidate called 2012 VP113 at the outermost edges of the Solar System, possibly confirming the existence of the Oort Cloud, the hypothetical vast reservoir of trillions of icy minor planetary bodies where comets are thought to originate. More interestingly, this discovery leaves the door open for the possibility of a bigger, more massive planet orbiting beyond the known reaches of the Solar System.

Throughout its 30-year career—consciously or unconsciously—the space shuttle was acknowledged to be one of the most dangerous piloted space vehicles ever brought to operational status. Although its first four teams of astronauts had ejection seats, their usefulness and survivability were questioned from the outset, and from STS-5 and the increase in crew size their inclusion became so impractical that they were done away with. Little escape capability of substance was available until after the separation of the Solid Rocket Boosters (SRBs), two minutes into flight, and NASA engineers worried constantly about the dangers of a failure of the shuttle’s three main engines. On five occasions, between June 1984 and August 1994, a handful of shuttle crews heard over the intercom a four-letter acronym that shook them to the very core: RSLS, denoting a Redundant Set Launch Sequence, indicative of a harrowing engine shutdown on the pad, right before launch.
